Substantial Income of Wealthy Households Escapes Annual Taxation Or Enjoys Special Tax Breaks

Policymakers should reconsider how the tax code treats the most well-off. Here is a closer look.

With the nation’s income and wealth highly concentrated at the top and growing more so in recent decades, policymakers should reconsider how the tax code treats the most well-off. High-income, and especially high-wealth, filers enjoy a number of generous tax benefits that can dramatically lower their tax bills. Eliminating or limiting these preferences would make the tax code more progressive and push back against inequality. It also would raise significant revenue that could be used to fund key priorities and help address the nation’s fiscal challenges.

A critical tax advantage for wealthy households is that much of their income doesn’t appear on their annual tax returns because the tax code doesn’t consider it “taxable income.” For example, taxes on capital gains (the increase in the value of assets such as stocks, real estate, or other investments) are effectively voluntary to a substantial extent: high-wealth filers may accumulate capital gains every year as their investments appreciate, but they don’t owe tax on those gains until — or unless — they “realize” the gain, usually by selling the appreciated asset. Wealthy individuals can wait to sell until it makes the most sense for them, such as a year in which they will have large capital losses to offset the gain. And, if a wealthy individual opts instead to pass on her appreciated assets to her son when she dies, neither she nor her son will ever owe capital gains tax on the assets’ growth in value during her lifetime. In contrast, people who earn their income from work (for example, from wages or salaries) typically have income and payroll taxes withheld from every paycheck; if their tax liability for the year exceeds those withheld taxes, they must pay the balance by the following April 15.

Further, a significant part of the income that does show up on wealthy households’ annual tax returns is taxed at preferential rates. Capital gains and dividends are taxed at a maximum income tax rate of 20 percent, far below the 37-percent top rate on wages and salaries.[1] Also, the 2017 tax law created a new 20-percent deduction for certain pass-through business income (income that the owners of businesses such as partnerships, S corporations, and sole proprietorships report on their individual tax returns), which lowers the tax rate on this income by up to 7.4 percentage points. The deduction disproportionately benefits wealthy people: 61 percent of the benefit will ultimately flow to the top 1 percent of households, the Joint Committee on Taxation (JCT) estimates. The 2017 law also slashed the corporate rate from 35 percent to 21 percent, which disproportionately benefits wealthy shareholders.

The amount of the nation’s income and wealth flowing to the most well-off has increased sharply in recent decades. (See Figure 1 and box.) Tax policy choices benefiting wealthy filers have contributed to these disparities. By the same token, new approaches to tax policy can push back against these trends.

Policymakers have a number of ways to raise more revenue from the most well-off. They fall into two broad categories:[2]

  • Expanding the types of income considered taxable. For example, instead of waiting to tax capital gains until assets are sold, the tax code could impose a “mark-to-market” system, which would impose tax annually on the gain in value of assets that high-income individuals hold, whether or not they are sold. Policymakers also could repeal the “stepped-up basis” tax break, which enables wealthy people who have avoided capital gains taxes on the growth of assets during their lifetimes to pass them to their heirs free of capital gains tax.
  • Improving taxation of income already taxed under the current system. For example, policymakers should repeal the 20 percent pass-through deduction. They also could end or scale back the preferential rates for capital gains and dividend income by raising their rates to match or come closer to the prevailing rates on ordinary income, such as wages and salaries. And they could broaden the tax base by narrowing or eliminating various unproductive tax breaks used primarily by large corporations and wealthy individuals, described later in this report.

Policymakers also should pursue a parallel effort to rebuild the IRS’ enforcement division and strengthen tax compliance efforts, which have been dramatically underfunded in recent years. The agency has fewer revenue agents (auditors who tend to audit the most complex returns) than in 1954, when the economy was roughly one-seventh its current size. As a result, the IRS in 2018 audited just 3.2 percent of tax returns showing incomes above $1 million, down from 8.4 percent of such returns in 2010. Rebuilding the IRS’ enforcement function will require a multi-year funding commitment to hire and train auditors and other staff. A reasonable initial goal would be to return funding to its inflation-adjusted 2010 level over four years.

Income, Wealth Are Highly Concentrated and Growing More So

Income and wealth are highly concentrated at the top and have grown more so in recent decades. The highest-income 1 percent of households received 12.3 percent of total household income after taxes and government transfers in 2016, up from 7.4 percent in 1979, according to the Congressional Budget Office (CBO).a The share going to the bottom 80 percent fell over that period, from 58.4 percent to 53.1 percent.b In other words, most of the decline in the bottom 80 percent’s share of household income mirrored the increase in the top 1 percent’s share.

The CBO data only go back to 1979, but estimates from economists Thomas Piketty, Emmanuel Saez, and Gabriel Zucman show that the top 1 percent’s share of after-tax income has reached a level not seen since before World War II.c Their data also show that the growth of the top 1 percent’s share of income has largely occurred among households at the very top: the top 0.1 and 0.01 percent.

Wealth inequality, which is even more pronounced than income inequality, has also grown in recent decades, according to the Federal Reserve’s Survey of Consumer Finances, the main source of data for the distribution of household wealth. The wealthiest 1 percent of households held 39.6 percent of wealth in 2016, up from 33.8 percent in 1983 — an increase representing trillions of dollars. The bottom 80 percent’s share fell from 18.7 percent to 10.1 percent over that period.d Data from Saez and Zucman also show that wealth inequality has reached levels not seen since before World War II and has been driven by a rapidly escalating share of wealth for households in the top 0.5 percent.e

The heavy concentration of income and wealth has an important racial dimension, because households of color are overrepresented at the lower end of the income and wealth distributions while white households are overrepresented among the wealthy. For example, 25 percent of all households were Latino or Black in 2016, but they represented 34 percent of the least wealthy 60 percent of households and less than 10 percent of the wealthiest 1 percent.f These inequities are rooted in policies that have been shaped by historic and ongoing racism and limit opportunity for households of color.g

This study measures income inequality differently than the CBO estimates. For instance, CBO uses Census data and IRS tax return data to estimate household income both before and after taxes. The Piketty, Saez, and Zucman estimates incorporate the portion of national income not captured in tax or survey data into the analysis of income inequality. That is, Piketty, Saez, and Zucman look at income flows in the broader economy and attempt to assign those income flows to households even if they don’t show up on tax returns or in survey data.

Income From Wealth Is Taxed More Lightly Than Income From Work

To understand how the tax code taxes income from wealth more lightly than income from work, one must first distinguish between labor income (such as wages, salaries, and employer-provided benefits), which flows from work, and capital income (such as dividends, interest, rental income, and capital gains), which flows from ownership of assets.

Most Americans primarily earn labor income; it constitutes at least 80 percent of the total income for each of the four bottom income quintiles, according to CBO.[3] (See Figure 2.) The vast majority of this labor income is wages and salaries, which are taxed at ordinary income rates.

For the top 1 percent of households, in contrast, capital income — most of which enjoys preferential tax rates[4] — constitutes 41 percent of their taxable incomes, while labor income makes up just 34 percent, according to CBO.[5] Most of the remaining 25 percent is pass-through business profits,[6] which are usually a combination of labor and capital income and also enjoy special tax preferences.[7] This means that most of the taxable income of the top 1 percent receives favorable tax rates. Moreover, these figures omit unrealized capital gains, which as noted, often don’t face income tax for years, if ever, and are highly concentrated in the top 1 percent.

The importance of capital income for households at the top not only helps explain why the tax code contains so many provisions that tilt in their favor, but also has important implications for designing effective policies to raise revenue in a progressive manner, as discussed below.

Tax Code Allows Wealthy to Exclude Much of Their Income from Tax Returns

Much of the income of the very well off never appears on their tax returns. Workers typically have income and payroll taxes withheld from every paycheck; this withheld income shows up on their tax returns when they reconcile how much they owe by April 15 each year. But that’s not the case for the investment income for wealthy households, because policymakers have given them several ways to delay income tax or even avoid it altogether.

Deferral of Capital Gains Income

Unlike other types of income, like wages, the amount of capital gain claimed on a tax return is often effectively voluntary due to the “realization principle,” which means that a capital gain is only taxed when the capital gain is “realized,” typically when the asset is sold. Only part of capital gains are realized in any given year. The rest are deferred, and no tax is immediately due, even if the unrealized capital gain makes up a significant share of a household’s income as reflected in the growth of its net worth.

The ability to defer capital gains taxes confers three benefits on taxpayers who can take advantage of this tax break:

  • Instead of paying taxes each year on their capital gains, they can continue earning returns on the money that they would have paid in tax, and these returns compound over time. Delaying by decades the day when taxes are due is a large benefit.
  • They can wait to sell assets until doing so is beneficial for other tax reasons. They may wait, for example, until a year in which they will be in a lower tax bracket or will have large capital losses to offset the gains, or they may hold on to assets in hopes of a future capital gains tax-rate cut. Wage earners typically do not have this option since they owe tax on their income in the year they receive it.
  • They can take advantage of many of the other tax benefits for capital gains discussed below, such as stepped-up basis.

This deferral option disproportionately benefits wealthy households. Not only do they receive the large bulk of capital gains (see discussion below), but unrealized capital gains make up 34 percent of the assets of the wealthiest 1 percent of households, which held $6.6 million in unrealized capital gains apiece, on average, in 2013. The comparable figures for households in the bottom 90 percent are just 6.1 percent and $9,000, respectively.[8]

Not surprisingly, many wealthy households take advantage of this very generous tax break. Research in the 1980s by Eugene Steuerle (now with the Tax Policy Center) found that less than one-third of overall capital income (including unrealized gains) was reported on individual tax returns.[9] And an important 2018 paper by Jenny Bourne, Steuerle, and others found that over the 2002-2006 period, when the stock market was delivering annual returns of 7-8 percent after adjusting for inflation, wealthy people were reporting taxable returns on their wealth of “less than 3 percent and the predominant rate was in the 1 to 2 percent range.”[10] The authors concluded that “these results are consistent with earlier work . . . indicating that in aggregate most capital income is not reported on tax returns.”[11]

The latter study also found that the share of income that households report on their tax returns declines as one moves up the wealth scale.[12] Berkshire Hathaway Chairman Warren Buffett is one example.[13] The value of Buffett’s main asset, Berkshire Hathaway stock, rose over 17 percent in 2010, from approximately $34.8 billion to $42 billion.[14] These figures imply income of roughly $7.2 billion. Yet in his tax returns for 2010 (which he made public via a letter to former Congressman Tim Huelskamp), Buffet’s adjusted gross income was $62.8 million, or less than 1 percent of that amount.[15]

Or consider Jeff Bezos, the founder of Amazon. The company’s filings with the Securities and Exchange Commission (SEC) show that he receives an annual salary of $81,840,[16] which is subject to ordinary income taxes each year.[17] As founder, however, Bezos owns a significant share of Amazon stock.[18] The value of Bezos’s Amazon holdings grew by more than $100 billion over the last decade, making him the world’s wealthiest person.[19] This $100 billion in income is only taxed when — or if — Bezos decides to sell some of his stock. This ability to defer tax on one’s primary source of income effectively makes the income tax largely voluntary for most of the income that people like Bezos receive, unlike for the salary income that middle-income people live on. Bezos sold Amazon shares worth roughly $6.3 billion between 2009 and 2018, according to SEC filings,[20] but the tax code ignores the rest of his $100 billion gain. Thus, his tax bill on a decade of stock sales likely was about $1.5 billion, or less than 1.5 percent of his increase in wealth due to the appreciation of his Amazon stock.

Wealthy owners of profitable corporations can choose to never sell their valuable stock and therefore avoid paying tax throughout their lives. If they need access to large amounts of cash, they have plenty of options besides selling their shares. Larry Ellison, the CEO of Oracle and one of the world’s richest people, pledged a portion of his Oracle stock as collateral for a $10 billion credit line.[21] In other words, he can borrow up to $10 billion, and if he fails to repay the debt, the bank can seize his Oracle shares. This lets him obtain cash without selling his shares; thus, he avoids paying taxes, and the stock can continue growing in value. Though he must pay interest on the debt and eventually pay back amounts borrowed, this is often a much cheaper strategy than selling stock and paying capital gains taxes, particularly when interest rates are low.

These examples show that, as a recent study explained, “[i]t is a simple fact that billionaires in America can live very extraordinarily well completely tax-free off their wealth. It is equally a simple fact that people who live off paid wages cannot do so.”[22]

Targeted Capital Gains Tax Breaks

The tax code contains other ways to defer or avoid capital gains tax. These special tax breaks are often targeted to a specific industry, such as real estate, or are intended to encourage certain types of supposedly socially beneficial investments, but instead often reward wealthy investors for making investments they likely would have made anyway.

One example is the “like-kind exchange” loophole, which allows people to sell certain types of assets and still avoid paying tax on the realized capital gain in the year of the sale. Originally meant to exempt small-scale and barter transactions (such as farmers trading horses) from taxation, like-kind exchanges are now used extensively in the commercial real estate industry.

For example, suppose an investor buys a small office building for $10 million and its value rises over time to $15 million. She thinks it has little additional potential to gain in value and wishes to invest in real estate somewhere else. If she sells the building for $15 million, she’ll owe tax on the $5 million capital gain. But if she exchanges it for a ski lodge, for example, the $5 million won’t be subject to tax until she sells the ski lodge — and she could continue deferring tax by exchanging that property for yet another.

The 2017 tax law eliminated like-kind exchanges for certain assets (such as vehicles, equipment, and artwork) but retained them for real estate, so wealthy real estate investors can continue to sell buildings without claiming the gains from those sales on their income tax returns. In fact, they can buy and sell properties throughout their lives and never pay tax on the gains — and then combine this tax avoidance with stepped-up basis at death to avoid tax liability completely, as the next section of this paper explains.

Another example is the opportunity zone tax break created by the 2017 tax law, which lets investors defer taxes that they would otherwise owe on capital gains if they invest in designated low-income areas. If investors hold on to their opportunity zone investments for a certain number of years, they can qualify for additional tax breaks — including a permanent capital gains tax exemption on future gains on their opportunity zone investments. The opportunity zone tax break was promoted as a measure that would encourage substantial new investment in low-income areas, but it doesn’t require investors to make investments that actually produce public benefits. This raises questions about whether its main effect will be simply to boost investors’ profits. [23]

Yet another example is the tax break for investing in so-called “qualified small business stock,” which allows early investors in corporations to avoid capital gains taxes when they sell their stock. This tax break often fails to target truly small businesses (which are typically organized as pass-through entities rather than corporations and thus do not qualify for this tax break). Instead, it often serves as a large tax break for investors in successful tech startups, which likely could have attracted sufficient capital even without qualified small business stock.[24] Furthermore, the combination of the qualified small business stock tax break and the 2017 tax law’s large corporate rate cut created what one accounting firm called a “supercharged tax planning opportunity”[25] that may cause more companies to form as corporations in order to benefit from the tax break.

Stepped-Up Basis

One of the tax code’s largest subsidies for capital gains is the stepped-up basis tax break. If an investor holds on to an asset (such as stock) and passes it on to an heir instead of selling it, neither she nor her heir owes capital gains tax on its increase in value during her lifetime. (Technically, the asset’s basis — or the price paid for it — is “stepped up” to its fair market value at the time of inheritance.) Stepped-up basis encourages wealthy people to turn as much of their income into capital gains as possible and hold on to assets until death, when a lifetime of gain becomes permanently exempt from tax. (The asset, however, may be subject to the estate tax, as explained below.)

Combined with the benefits of deferral and the other targeted capital gains tax breaks discussed above, stepped-up basis allows large corporate stockholders and other wealthy investors to pay no income tax on the increase in assets’ value during their lifetimes and then pass the assets on to their heirs, who pay no income tax on those inheritances. For example, Steve Jobs, the former Apple CEO, received an annual salary of $1, as reported on the company’s SEC filings.[26] Instead of a traditional salary, he received shares of Apple stock worth $75 million in the early 2000s.[27] He likely paid ordinary income tax on the value of those shares when he received them as income. But because he never sold the shares during his lifetime, he never paid tax on the subsequent massive gain as Apple’s stock skyrocketed.[28] At his death, Jobs’ Apple stock was worth roughly $2 billion, and all of that gain was permanently exempt from income tax.

Weakened Estate Tax

Many people may assume that all income faces the income tax, meaning that wealthy people pay tax on their income throughout their lives. But that’s not how it works. As explained above, wealthy people can permanently avoid federal income tax on capital gains, one of their main sources of income, and heirs pay no income tax on their windfalls.

The estate tax provides a last opportunity to collect some tax on income that has escaped the income tax. The amount of income involved is considerable: more than half of the value of the largest estates is unrealized capital gains income that has never been taxed. (See Figure 3.) The estate tax, therefore, serves as an important backstop to the income tax.

In addition, the estate tax could push back against inequality by imposing some tax on the windfall an heir receives. Though levied on the estate, the tax effectively falls on heirs, research shows.[29] Large inheritances play a significant role in the concentration of wealth: they represent roughly 40 percent of all wealth and account for more than half of the correlation between parents’ wealth and that of their children.[30]

Despite the need for a robust estate tax, a decades-long political effort to undermine the estate tax has severely weakened it.[31] Most recently, the 2017 tax law doubled the amount that a wealthy couple can pass tax-free to their heirs, from $11 million to $22 million, and indexed these thresholds for inflation going forward. Today, fewer than 1 in 1,000 estates are expected to owe any estate tax.[32]

Moreover, the few estates large enough to potentially face the tax can use loopholes to reduce or eliminate their estate tax liability, such as by artificially valuing their assets at less than their true value. (For example, the “minority ownership discount” allows an estate that owns a minority share of a business to value — and therefore pay estate taxes on — the estate’s share of the business below its fair market value.[33]) IRS researchers analyzing the estate tax returns of deceased prior members of Forbes magazine’s annual list of the 400 wealthiest Americans concluded that on average, their wealth as reported for tax purposes was roughly half of Forbes’ estimate of their wealth.[34]

Another common planning technique is to use grantor retained annuity trusts (GRATs) to pass along considerable assets tax-free. Under this tax break, a wealthy individual puts assets such as stock or real estate into a trust in return for a stream of fixed payments, typically over two years, that total the initial value of those assets plus interest at a rate set by the Treasury. If the assets in the trust rise in value by more than the Treasury rate, the gain goes to the trust beneficiary (such as the trust owner’s child) tax-free. If the assets don’t rise in value by more than the Treasury rate, the assets still go back to the trust owner through the fixed payments received. Such techniques have been described as a “heads I win, tails we tie” bet.[35] The Walton family successfully fought the IRS in court to exploit this loophole,[36] and casino owner Sheldon Adelson was estimated at one point of having used multiple GRATs that will ultimately allow him and his heirs to bypass the estate tax on $7.9 billion in wealth.[37] This device reportedly is also popular among wealthy Silicon Valley and Wall Street financiers.[38]

Putting all these tax breaks together, wealthy people can escape taxation on much of their capital income throughout their lives and have their income tax liability on these gains wiped out at death. They also can use loopholes to reduce or eliminate their estate tax liability. And their heirs owe no income tax on those inheritances — even though other types of earned and unearned income, such as lottery or gambling winnings, face income taxes. Thus, massive fortunes can accumulate across generations largely tax-free.

Even Taxable Income Often Enjoys Advantages

Even the income that wealthy people have to include on their annual tax returns often enjoys favorable tax treatment. This includes a top tax rate that’s low by historical standards, a substantially lower rate for capital gains than for wages and salaries, and a new deduction for certain pass-through income.

Top Tax Rate

The top income tax rate — which applies not only to wages and salaries but also interest, stock options, and some pass-through business income — is 37 percent, which is well below the post-World War II average of 59 percent.[39] During the early postwar decades, a time of both robust economic growth and broadly rising living standards, the top rate was 70 percent or higher, although much income escaped that rate. (See Figure 4.) In recent decades, a period of surging incomes at the top and stagnant working-class incomes,[40] it has been considerably lower. Most recently, the 2017 tax law reduced it from 39.6 percent to 37 percent for married couples with taxable incomes above $600,000, exclusively benefiting the top 1 percent.

In addition, the income threshold at which the top bracket kicks in does an increasingly poor job of differentiating between the wealthy and the extremely wealthy. Between 1913 and 1970, the income level at which the top rate took effect was usually well above the threshold for the top 0.1 percent (and in most years, even the top 0.01 percent), a recent analysis by The Washington Post found.[41] Yet, starting in the 1970s, the top bracket threshold began to fall relative to the incomes of those extremely wealthy groups. Today, the top bracket begins at $600,000 for a married couple, which is modestly above the threshold for the top 1 percent (roughly $480,000 in adjusted gross income in 2015[42]) but well below the $2 million threshold for the top 0.1 percent.

Someone making $600,000 has a high income by any reasonable measure, but that is still much smaller than $7 million or $70 million. Yet the tax code fails to distinguish between these different levels of affluence by imposing gradually higher marginal tax rates on them.

Capital Gains Rate

Much of wealthy households’ taxable income is taxed at lower rates than ordinary income. A prime example is long-term capital gains, which today are taxed at 20 percent, plus a 3.8 percent surtax known as the Net Investment Income Tax (NIIT).[43] This means that not only is the tax on capital gains largely voluntary (since it is only paid when taxpayers sell assets), but when investors actually pay it, they get a special low rate.

This rate is particularly important to the wealthiest households because capital gains are so concentrated. The top 1 percent received 69 percent of the taxable long-term capital gains in 2018 (see Figure 5), according to the Tax Policy Center. More than half went to the top 0.1 percent alone. And while 3 in 4 households in the top 0.1 percent reported taxable capital gains income in 2018, fewer than 1 in 20 households in the bottom 60 percent did.[44] (These figures omit unrealized capital gains, which likely are even more concentrated at the top.)

Dividends Rate

A special tax rate for capital gains income is a longstanding tax break for investors; the low tax rate on dividends is much more recent. Historically, dividends were taxed at the same rates as wage and salary income, as well as most interest income. This changed in 2003, when policymakers temporarily cut the top rate on qualified dividends[45] from 38.6 percent to 15 percent; they later set a permanent rate of 20 percent. Like capital gains, dividends are subject to the 3.8 percent NIIT. Therefore, qualified dividends are taxed at the same special low rate as long-term capital gains.

Proponents argue that a low tax rate on dividends promotes investment and job creation, but a landmark study by University of California, Berkeley Professor Danny Yagan found that the 2003 dividend tax rate cut “caused zero change in corporate investment and employee compensation”[46] while providing a windfall to high-income people. Dividend income is highly concentrated: 46 percent of qualified dividend income flows to the top 1 percent of households, and 28 percent flows to the top 0.1 percent.[47] Nearly 89 percent of the top 0.1 percent of households have dividend income, compared to just 7.9 percent of the bottom 60 percent of households.[48]

The combination of lower rates on both dividends and capital gains creates a large subsidy for wealthy investors. More than half of the tax benefits from these lower rates go to the top 0.1 percent of households; less than 5 percent go to the bottom 60 percent of households.[49] In 2018, the lower rates raised after-tax incomes for the top 0.1 percent by $554,000 apiece (7.4 percent), on average, the Tax Policy Center estimates, compared to less than $30 for households in the bottom 60 percent.[50] (See Figure 6.)

Pass-Through Deduction

Historically, pass-through businesses — including partnerships, S corporations, and sole proprietorships — have offered a major tax advantage over corporations. The federal government taxes corporate income twice: profits are taxed first at the business level (through the corporate income tax), and after-tax profits are taxed a second time to the extent that shareholders receive them as dividends. Pass-through income, on the other hand, “passes through” the business and is taxed only once, on the returns of the business’s owners — at the same rates that would apply if the owners earned the income directly.

Thus, before the 2017 tax law sharply cut the corporate rate, the combined federal tax rate on corporate income (including the corporate tax and the tax rate on dividends) was significantly higher than the top rate on pass-through income.[51] Largely as a result, pass-through businesses have replaced corporations as the dominant form of business, earning more than 52 percent of all business income in 2012, up from less than 20 percent in 1980.[52]

Proponents of tax cuts for pass-through businesses often hold up small businesses as the intended beneficiaries. Most pass-through businesses are indeed small and typically make modest profits, but pass-through income is highly concentrated. Partnerships, a common pass-through structure, are one example: 69 percent of partnership income flows to the top 1 percent of households.[53] Many large, profitable businesses are structured as pass-throughs — including financial firms such as hedge funds and private equity firms, real estate businesses, oil and gas companies, and large multinational law and accounting firms — and they generate the bulk of pass-through income.

As noted, the 2017 tax law created a 20 percent deduction for certain pass-through income. The deduction is worth much more, per dollar deducted, to high-income business owners than to small business owners with modest incomes because the former are in higher tax brackets. And because high-income households receive the bulk of pass-through income, the deduction’s overall tax benefits are heavily tilted to the top as well: 61 percent of the tax benefits from the deduction will go to the top 1 percent of households in 2024, JCT estimates, while just 4 percent will go to the bottom two-thirds of households.[54]

The deduction gives wealthy business owners a new incentive to recharacterize their labor compensation as pass-through profits. Such incentives exist even apart from the deduction; for example, many S corporation shareholders — who receive both wage or salary income from the company and a share of the company’s profits but pay Medicare taxes only on the wage or salary portion — underreport the share of their income that comes from wages and salaries and overstate the share that is pass-through business income in order to reduce their Medicare taxes. A 2009 Government Accountability Office report found that 13 percent of S corporations underpaid wage compensation in 2003 and 2004, resulting in $23.6 billion in underreported wages and salaries — and roughly $3 billion in lost Medicare tax revenues during those years.[55]

On top of the ability to minimize Medicare taxes, pass-through owners now benefit from the 2017 tax law’s pass-through deduction, which gives qualifying filers a 7.4 percentage point tax rate reduction on certain pass-through income. As a result, the top income-tax rate is 37 percent for wages and salaries but just 29.6 percent for pass-through income that qualifies for the deduction.[56] This further encourages pass-through owners to recharacterize their labor compensation as pass-through profits, which can allow them to avoid the top rate on even more of their labor income.

Corporate Tax Rate

The centerpiece of the 2017 tax law was a cut in the corporate tax rate from 35 percent to 21 percent. Corporate rate cuts largely benefit wealthy corporate shareholders; one-third of the benefits ultimately flow to the top 1 percent of households, according to TPC.[57]

Before the 2017 tax law, there was bipartisan support for reducing the corporate rate while expanding the corporate tax base to keep the changes revenue neutral. President Obama, for example, proposed lowering the rate to 28 percent and broadening the base to fully offset the cost.[58] The 2017 tax law, however, cut the rate by twice as much as the Obama proposal and lacked significant base-broadeners. As a result, the corporate provisions will cost $668 billion over the first ten years, JCT estimated.[59] Corporate tax payments, which neared $300 billion in 2017 (before the law took effect), plummeted to $205 billion the following year, well below CBO’s prediction of $243 billion.[60]

Not only did the 2017 law’s corporate rate cut disproportionately benefit wealthy shareholders, but the wide gap it created between the 37-percent top individual tax rate and the 21-percent corporate rate gives wealthy individuals an incentive to shelter their income in corporations.[61] For example, a wealthy bond investor owning several million dollars of bonds can transfer them to a new corporation that she has created solely to hold these assets — and potentially pay tax on the interest income at roughly half the rate she would pay if this income faced the individual income tax rate.[62] She might eventually have to pay taxes on dividends or capital gains on the wealth that accrues in the corporation, but she could defer that second layer of tax for decades and even avoid it altogether by passing the corporation on to her heirs. Before the 2017 law took effect, the corporate and top individual rates were close enough to each other that this type of sheltering didn’t make sense for most wealthy taxpayers.

Several Options Exist to Tax High Incomes, Large Fortunes More Effectively

The tax code’s approach to taxing the income of wealthy people and the transfer of large fortunes is deeply flawed. Much of the income of wealthy people doesn’t show up on their tax returns, and much of what does show up enjoys special breaks.

There are a number of sound proposals to tax high incomes and large fortunes more effectively, which could mitigate income inequality while also raising new revenue that could help address various national policy priorities. Some proposals expand the types of income considered taxable; others improve taxation of income already taxed under the current system. The options below do not constitute a single agenda; some are complementary (such as eliminating both stepped-up basis and preferred rates on capital gains), while others are alternatives (such as strengthening the estate tax or creating an inheritance tax). Nor is the set of options below intended to provide an exhaustive list of possible ways to raise substantial revenue in a progressive manner. For example, another such option, not covered in this paper, would be to impose a very small percentage tax — often referred to as a financial transactions tax (FTT) — on the sale of securities such as stocks and bonds.[63]

Expanding the Types of Income Considered Taxable

Adopting Mark-to-Market Taxation of Capital Gains

Instead of waiting to tax capital gains until assets are sold, the tax code could institute a mark-to-market system that applies to households with considerable wealth and levies tax annually on the gain in value of those households’ assets whether or not the assets have been sold.[64] For example, if a wealthy investor bought publicly traded stock on January 1 for $1,000 a share and the stock’s trading price was $1,100 on December 31, she would pay capital gains tax on the $100 increase per share even if she didn’t sell the stock that year. As discussed more below, policymakers could design a mark-to-market tax to ensure that it applies only to wealthy households.

Since wealthy taxpayers would no longer have a tax incentive to defer asset sales, they would sell assets when it made economic sense to do so. And eliminating this tax incentive would significantly increase capital gains tax collections.

A related reform that would also raise capital gains revenue collections would be to raise the capital gains tax rate. Under current law, the rate that would raise the most revenue is approximately 30 percent, according to JCT. At rates above 30 percent, JCT believes that revenue would begin falling because taxpayers would substantially increase tax avoidance, such as by delaying asset sales.[65] Under a strong mark-to-market system that largely eliminates such incentives, however, wealthy taxpayers could no longer avoid capital gains taxes by deferring asset sales. Thus, policymakers could generate further significant revenue, primarily from the very top of the income distribution, by raising capital gains rates to match the prevailing rates on ordinary income.

One challenge of a mark-to-market tax on capital gains is the need to value assets and impose tax each year. For certain types of assets, like a work of art or an ownership interest in a closely held company, annual valuations could impose administrative burdens on taxpayers and lead to tax avoidance, as taxpayers shop around for the lowest appraisal. To address this problem, the tax code could treat non-publicly-traded assets differently: instead of imposing an annual capital gains tax on unrealized gains in those assets, it could continue to defer taxes on them until realization, but impose a one-time “deferral charge” when the asset is eventually sold, comprising the amount of capital gains tax plus an amount similar to interest that would be based on how long the asset was held before it was sold. This would still reduce the incentive to defer sales of capital assets compared to the current tax code. It would also make other complementary reforms we discuss here, such as raising capital gains rates and closing other loopholes that allow some capital gains to go untaxed, more effective and efficient.

Policymakers have several design alternatives to ensure that a mark-to-market system applies only to wealthy investors. They could, for instance, exempt all capital gains for taxpayers who are below a specified income or wealth threshold (these taxpayers would only owe capital gains tax when the gains are realized), or grant all taxpayers a lifetime exemption of a specified dollar amount of capital gains, above which they would have to use the mark-to-market system.

Senate Finance Committee Ranking Member Ron Wyden recently released a white paper calling for a mark-to-market tax system for capital gains along with an increase in the capital gains rate to the same rates as apply to ordinary income.[66] Under Senator Wyden’s proposal, large capital gains on corporate stock and other securities that wealthy households own would be taxed annually, while non-publicly traded assets would be subject to a deferral charge at the time of sale. Wyden estimates that his proposal could raise $1.5 trillion to $2 trillion over ten years.[67]

Addressing Other Provisions Encouraging Capital Gains Tax Avoidance

President Obama proposed limiting the amount of capital gain that a taxpayer can defer through “like-kind exchanges” to $1 million per year and disallowing the like-kind exchange loophole for sales of artwork or other collectibles.[68] This would have raised more than $47 billion over 2017-2026. In contrast, the 2017 tax law’s reform of the like-kind provision, which retained the loophole for real estate, is expected to raise $31 billion over 2018-2027.[69] The like-kind exchange tax break remains costly and unwarranted, costing roughly $9 billion a year in lost revenue.[70] The best course of action here would be simply to eliminate this tax break.

Furthermore, because the opportunity zone and qualified small business stock tax breaks directly benefit wealthy investors and may fall well short of producing socially beneficial investment on a substantial scale, policymakers should reconsider and, at a minimum, substantially reform and tighten them — and devote the freed-up resources to investments more directly benefiting low- and moderate-income people and communities.

Ending Stepped-Up Basis

Policymakers should repeal stepped-up basis by taxing the unrealized capital gains of affluent households when appreciated assets are transferred to heirs. Since future tax liability on unrealized capital gains would no longer be eliminated at death, affluent owners of valuable assets would have less incentive to defer tax by waiting to sell them; instead, they would be more likely to sell the assets when it made economic sense to do so. (As noted, this change also would allow policymakers to raise substantial revenue by raising capital gains tax rates, since investors could not avoid those taxes by holding more assets until death.)

Such a measure can be designed to shield most or all middle-class households. President Obama proposed repealing stepped-up basis for most capital gains over $350,000 (including $250,000 for personal residences and $100,000 of other gains). Such thresholds could be set where policymakers want to place them. President Obama’s proposal also would have retained rules allowing taxpayers to donate property to charitable organizations tax-free while allowing a deduction equal to the property’s fair market value, thereby exempting from federal income tax the appreciation that occurred while the taxpayer held the assets. JCT estimated that the Obama proposal, along with an increase in the maximum rate on capital gains and dividends to 28 percent, would have raised $250 billion over ten years.[71]

Adopting a mark-to-market system would partially address the problem of stepped-up basis by eliminating (for wealthy investors) capital gains deferral until death, at least for publicly traded assets whose gains would be taxed annually. For other asset classes, however, repeal of stepped-up basis would be beneficial even if a deferral charge is imposed. Stepped-up basis should also be repealed for gains accrued by wealthy investors before imposition of a mark-to-market system if those gains aren’t taxed upon transition to the new system.

Imposing a Wealth Tax on Very Wealthy Households

Annually taxing wealth — whether via a wealth tax or changes to the income tax that have a similar effect — would fundamentally change the way the federal tax code treats wealthy taxpayers and raise substantial revenue while reducing inequality.

A wealth tax would apply to a wealthy taxpayer’s overall stock of capital without regard to her actual gains or losses from that wealth. This would be analogous to the annual state and local property tax that millions of homeowners across the country pay each year on the value of their homes.[72] For instance, Senator Elizabeth Warren has proposed a 2 percent tax on the wealth of households with more than $50 million in net assets and a 3 percent tax on households worth more than $1 billion. Economists Emmanuel Saez and Gabriel Zucman estimate that the proposal would affect fewer than 0.1 percent of households and would raise around $2.75 trillion over ten years,[73] although their cost estimate has been questioned and may be too high.[74] The Institute on Taxation and Economic Policy estimates that a lower wealth tax rate of 1 percent on households with more than about $32.2 million (that is, the top 0.1 percent of households in 2020) could raise $1.3 trillion over ten years.[75]

An alternative would be an “imputed income tax,” which would assume that a taxpayer’s stock of wealth generates a specified, standard rate of return as a proxy for income and require taxpayers to claim those assumed returns as part of their income on their annual tax returns. This is designed to address gaps in the current system under which much of the income of wealthy people does not show up on their tax returns.

The Netherlands, for example, imposes a tax that is formally part of its income tax but operates similarly to a wealth tax by taxing an assumed return on a taxpayer’s publicly traded stock and some other forms of wealth. Likewise, Professor Ari Glogower has proposed adjusting key parameters of the existing federal income tax — such as deductions, credits, or tax rates — to account for significant wealth holdings.[76] In both cases, taxpayers with great wealth would increase the income tax they pay as a result of that wealth, much like their rates and tax benefits are currently adjusted for characteristics such as marital status, age, and investment income.

As with any tax policy proposal, these options have advantages and disadvantages. As noted, performing valuations annually of certain hard-to-value assets like artwork could create administrative challenges. Senator Warren’s plan would both dramatically increase the IRS budget, enabling it to devote more staff to audits, and make the valuation process somewhat less complex and prone to avoidance.

Structuring a wealth tax as a part of the existing income tax could mitigate concerns about the constitutionality of a wealth tax. The Constitution requires so-called “direct taxes” to be “apportioned” among the states in proportion to their populations, meaning that a tax needs to raise revenue from each state in proportion to that state’s share of the U.S. population.[77] As a result of this constitutional requirement, the Supreme Court held in 1895 that a federal income tax was unconstitutional;[78] it took enactment and ratification of the 16th Amendment to the Constitution in 1913 to enable a federal income tax to be instituted. Legal scholars debate which taxes are “direct taxes” under the Constitution and whether a wealth tax like the Warren proposal would in fact be an unconstitutional direct tax,[79] but many have expressed concern that the current Supreme Court could rule that a wealth tax violates the Constitution. Though there are strong legal arguments for the constitutionality of a wealth tax, policymakers might be able to avoid the debate by structuring the tax through the existing income tax.

Taxes on wealth — whether structured as a wealth tax or an imputed income tax, or whether pursued through the capital gains, dividends, and estate tax reforms discussed here, which are other ways of taxing wealth — would help counter the decades-long increase in wealth inequality and provide a significant source of new progressive revenue at a time when our nation sorely needs it.

Strengthening the Estate Tax

Policymakers also should bolster the estate tax to ensure that wealthy heirs pay their fair share in tax. For example, they could restore the tax to the parameters that were in place in 2009 — that is, a $3.5 million exemption (effectively $7 million for a couple) and a 45 percent top estate tax rate. Doing so could raise about $160 billion over ten years.[80]

Policymakers could also enact rules to prevent abuses associated with GRATs and excessive valuation discounts, such as through use of the minority ownership discount. Obama Administration proposals to address these abuses would have raised $14 billion over ten years if the 2009 estate tax parameters were also restored.[81] Going beyond the Obama proposals to close these loopholes entirely could raise still more.

Enacting an Inheritance Tax

An alternative to strengthening the estate tax would be to replace it with an inheritance tax, which is levied on the income that heirs receive rather than on the value of the estate itself. This reform would complement repeal of stepped-up basis at death: repealing stepped-up basis would tax unrealized gains that accrued tax-free during the deceased person’s lifetime, and the heirs — who are considered separate legal persons from their parents — would then pay inheritance tax on very large windfalls.

The tax code defines taxable income broadly to include items such as lottery and gambling winnings, forgiven debt, and fringe benefits from employers like paid moving expenses. In each case, tax is imposed on an economic gain. Taxing heirs on their economic gains (their inheritances) would subject them to the same standards that apply to everyone else.

Moreover, inheritance taxes encourage work, unlike taxes on labor. Inheritances can make people much richer, which may encourage them to work less. Treasury Department economist David Joulfaian found that “an inheritance of $1 million, other things equal, reduces labor force participation by about 11 percent.”[82] By reducing the windfall, an inheritance tax encourages heirs to work more than they otherwise would. Similarly, a recent European study concluded that every euro of inheritance taxes is “accompanied by an additional nine cents of labour tax payments from heirs” due to increased work.[83]

New York University Law Professor Lily Batchelder, a noted expert on this topic, has proposed key parameters for an inheritance tax that would replace the estate tax. Her proposals would exempt inheritances up to a certain amount (ranging from $1.25 million to $2.1 million per person) from the tax; inheritances above this threshold would be subject to income tax at ordinary rates plus a surcharge (as a proxy for payroll taxes, from which inherited income is exempt) ranging from 10 percent to 15 percent. Based on IRS data and prior JCT analyses, she estimated that replacing the prevailing estate tax with her proposal would have raised between $199 billion and $670 billion more over the 2016-2026 period, depending on the exemption amount and the rate applied.[84]

Improving Taxation of Income Already Taxed Under the Current System

Increasing the Top Rate and/or Enacting an AGI Surtax

Policymakers can raise the current top income tax rate and design the rate increase so it applies to a broad swath of income that includes not only ordinary income but also capital gains, dividends, and pass-through income. They also can enact a surtax on taxpayers with very high adjusted gross incomes (AGI) to help prevent wealthy filers who benefit from preferential rates and other tax avoidance strategies from largely escaping the top income tax rate.

Although the final version of the Affordable Care Act did not include an AGI surtax, the House of Representatives passed a 5.4 percent surcharge on couples’ AGI above $1 million as part of its original version of the Affordable Care Act in 2009. CBO estimated that the surtax would have raised $461 billion over ten years.[85] More recently, the Economic Policy Institute has estimated that a 10 percent surtax on incomes over $2 million could raise $850 billion over ten years.[86]

Ending Preferential Rates for Capital Gains and Dividends

One of the simplest ways to ensure that the tax code does not reward wealth over work is to end the preferential rates for capital gains and dividend income by raising their rates to match the prevailing rates on ordinary income.

This step is advisable for another reason as well: raising the top income tax rate without addressing the tax preferences for capital gain income would increase the relative tax advantages of capital gains income, likely causing wealthy filers to recharacterize even more of their labor income as capital income.

If policymakers also adopted the reforms to stepped-up basis and capital gains deferral mentioned above, wealthy taxpayers would have fewer ways to avoid capital gains taxes, and an increase in the capital gains rate above about 30 percent would become feasible substantively and raise more revenue. This underscores the importance of those reform proposals: they raise revenue not only directly but also indirectly by reducing incentives for tax avoidance.

Dividends, too, should be taxed as ordinary income. As discussed above, dividends have historically been taxed at ordinary rates, and creating a special low tax rate on dividends did not increase corporate investment.

Eliminating Preferences for Pass-Through Businesses

The 2017 tax law’s 20 percent pass-through deduction lacked a solid policy rationale, and its arbitrary design concerning which income types and industries can qualify for the deduction invites rampant tax avoidance. New York University Law Professor Daniel Shaviro has described it as “the worst provision ever even to be seriously proposed in the history of the federal income tax.”[87] Repealing it and taxing pass-through business income at the same rates as wages and salaries would end the current incentive to game the deduction and recharacterize labor income as pass-through profits. Moreover, raising the top rate on wages and salaries without eliminating the pass-through break would enlarge the gap between the tax rates for qualifying pass-through income and for wage and salary income, encouraging even more wealthy taxpayers to recharacterize their labor compensation as pass-through profits.

Accordingly, policymakers should repeal the pass-through deduction. They should also ensure that all pass-through income faces either the Medicare tax or the NIIT. Eliminating the deduction would save $387 billion over ten years (effectively ending it for 2019-2025, since it is set to expire in 2026).[88] Closing the loophole around Medicare taxes and the NIIT would raise up to $200 billion.[89]

Another policy that warrants consideration is an entity-level tax on large pass-through businesses — either a separate tax or a requirement that these entities be treated as corporations for tax purposes. The Obama Administration proposed a similar reform in 2012.[90] The Congressional Research Service has estimated that subjecting pass-through businesses with more than $50 million in receipts to the corporate income tax would only affect 0.3 percent of S corporations and 0.2 percent of partnerships.[91] But because pass-through income is heavily tilted to these high-earning entities, the proposal would affect much larger shares of S corporation and partnership receipts: 30 percent and 41 percent, respectively.[92] Thus, it could raise significant revenue, particularly if paired with an increase in the corporate rate.

Raising the Corporate Tax Rate

Many of the reforms above would reduce or eliminate wealthy taxpayers’ incentive to use corporations as a tax shelter for their labor and interest income. Mark-to-market taxation of capital gains, eliminating stepped-up basis, ending preferred rates on capital gains and dividends, and a wealth tax all would make this avoidance strategy less attractive.

Increasing the corporate rate and broadening the corporate tax base are also important steps for reducing wealth inequality and raising revenue. The corporate income tax is one of the most progressive parts of the tax code, and it accounted for roughly 10 percent of federal tax revenue before the 2017 tax law.[93] Much of the capital income of wealthy households escapes individual taxation through trusts, stepped-up basis, and various forms of tax avoidance or evasion; the corporate income tax helps ensure that this income faces some layer of tax. Raising the rate to 28 percent or somewhat higher, broadening the base through policies such as strengthening rules preventing offshore profit shifting, and limiting interest deductibility would make the corporate tax a more effective form of wealth taxation.

Policymakers Should Bolster IRS Enforcement

The U.S. tax system relies on voluntary compliance, high levels of societal trust, and IRS enforcement as a backstop and deterrent. Historically, compliance has been relatively high compared to other countries,[94] but there is an urgent need to rebuild the IRS’ enforcement function, particularly its ability to ensure that wealthy people pay the taxes they owe.

Policymakers have cut overall IRS enforcement funding by 25 percent since 2010, after adjusting for inflation, and the enforcement division has lost roughly 30 percent of its workforce.[95] These cuts have taken a severe toll. For example, the IRS audited just 3.2 percent of millionaires in 2018, down from 8.4 percent in 2010.[96] (See Figure 7.)

The cuts in IRS enforcement occurred even as highly publicized scandals underscored the lengths to which some wealthy individuals will go to evade taxes. As a report from the Senate’s Permanent Subcommittee on Investigations noted in 2008:

Each year, the United States loses an estimated $100 billion in tax revenues due to offshore tax abuses. Offshore tax havens today hold trillions of dollars in assets provided by citizens of other countries, including the United States. The extent to which those assets represent funds hidden from tax authorities by taxpayers from the United States and other countries outside of the tax havens is of critical importance.[97]

A recent Government Accountability Office report found that funding constraints have severely hampered IRS implementation of the Foreign Account Tax Compliance Act, which was enacted in 2010 to reduce tax evasion by increasing the transparency of offshore accounts. Congress should examine whether the IRS has the resources it needs to vigorously pursue this important area of tax compliance.

ProPublica recently reported that the IRS had only about the same number of revenue agents in 2018 as in 1953, when the economy was one-seventh its current size[98] and wealthy households’ financial arrangements were far less complex. The proliferation of convoluted multi-tiered partnership structures and shell corporations, complicated financial instruments, and foreign bank accounts in low-tax countries has created serious enforcement problems. For instance, the federal indictment of former Trump campaign officials Paul Manafort and Richard Gates lists 17 pass-through entities established in the United States and a dozen entities established in Cyprus, and states that Manafort and Gates “hid the existence of foreign companies and bank accounts, falsely and repeatedly reporting to their tax preparers and to the United States that they had no foreign bank accounts.”[99]

Understanding and uncovering sophisticated tax fraud of this magnitude requires significant time and expertise. It’s worth noting that Manafort’s foreign tax evasion was discovered not through a typical tax audit but through a separate criminal investigation; this suggests that considerable tax evasion goes unnoticed by traditional IRS enforcement mechanisms and underscores the urgency of rebuilding the IRS enforcement division, focusing on tax compliance by very high-income households.

Rebuilding the IRS’ enforcement function will require a multi-year funding commitment because the IRS must hire and train a significant number of auditors and other staff, which requires time and some funding certainty. A reasonable initial goal would be to return funding for the enforcement account itself (plus the related operations support account, which includes office space, information services, and other functions that support the enforcement division) to its inflation-adjusted 2010 level over four years.

Funding for the enforcement account fell by 25 percent between 2010 and 2019, after adjusting for inflation, from $6.5 billion to $4.9 billion (in 2019 dollars). Operations support fell by 22 percent, from $4.8 billion to $3.7 billion.[100] (See Figure 8.) To return to the 2010 inflation-adjusted levels by 2023, funding would need to rise (relative to the 2019 level) by $970 million per year each year for the next four years, with $575 million going for enforcement and $395 million for operations support.

This is especially true for the pass-through business income of owners who work for the companies they own, because their compensation is, by definition, a mixture of capital and labor. The owner of a major beer distributor, for example, invests capital in warehouses and trucks, and some of the profits reflect the return on that investment. But she may also contribute labor to the business — recruiting employees, managing the accounting records, and seeking new business opportunities, for example. These activities also help generate the company’s profits but reflect a return on her labor rather than on her investment. When she reports her profits on her individual tax return, she will enjoy special privileges on the total profit, even though a large share of it likely reflects her labor.

[33] For purposes of estate and gift taxes, taxpayers may value minority ownership interests in closely held businesses at below their fair market value, on the grounds that such ownership interests are presumably less valuable than a controlling interest. The Treasury Department under President Obama proposed a regulation that would have restricted this tactic for avoiding the estate tax, but the Treasury Department under President Trump withdrew it.

[51] Corporations previously faced a 35 percent top tax rate, plus a 23.8 percent top tax rate on dividends paid to shareholders, for a total blended tax rate of 50.47 percent. The 2017 law lowered the top corporate tax rate to 21 percent, so the combined rate on corporate income is now 39.8 percent. It also lowered the top individual tax rate (that is, the top rate paid on a wealthy business owner’s pass-through business income) from 39.6 percent to 37 percent, plus in some cases, the 3.8 percent Medicare tax, though some pass-through owners are exempt from that tax. Furthermore, with the 20 percent pass-through deduction, a pass-through owner’s tax rate can be reduced to 29.6 percent (or 33.4 percent, if the Medicare surtax applies).

In any case, anti-abuse rules rely on a strong IRS that can enforce these rules, but the IRS enforcement budget has significantly declined in recent years, undermining its ability to combat tax sheltering activity.

Professors Lily Batchelder and David Kamin, however, estimate that even with a 30 percent tax avoidance rate (double the avoidance rate that Saez and Zucman anticipate), a wealth tax similar to Senator Warren’s proposal would likely raise approximately $2 trillion over ten years.

This clause was part of the framers’ so-called “compromise” over slavery, which included the infamous requirement (since superseded) that each slave count as three-fifths of a free person for apportioning those direct taxes and determining the state’s number of House seats. A number of historians, constitutional scholars, and judges have argued that the requirement for direct taxes to be apportioned was intended to protect southern states from the federal government levying taxes on the ownership of slaves, including by making it harder to levy such taxes at rates sufficiently high as to effectively tax slavery out of existence.
