Why Upper Income Americans Are Bearing Larger Tax Burden?

The question of who should shoulder the nation’s tax burden has long been a contentious and deeply political issue in the United States. While debates about "fairness" and "equity" dominate public discourse, the reality, as reflected in tax data and policy changes over the years, is clear: upper-income Americans are paying a growing share of the country’s taxes. This trend has intensified over the past few decades and was further solidified during President Barack Obama’s tenure, particularly with the passage of the fiscal cliff deal and healthcare reforms that targeted high earners with new tax obligations.

A Promise Made and Kept

When President Obama campaigned in 2008, he pledged to make the wealthiest Americans pay their "fair share" of taxes. His administration argued that during the George W. Bush years, tax policies disproportionately favored high-income earners. This message—calling for the rich to contribute more—is a recurring theme among politicians because it appeals to the broader public and makes those of us who aren't "wealthy" feel better about the fairness of the system. Upon taking office, Obama worked to reverse that trend. The fiscal cliff deal, formally known as the American Taxpayer Relief Act of 2012, enacted at the start of 2013, was a cornerstone of that effort.

The deal allowed tax cuts for middle- and lower-income Americans to remain in place while allowing rates on the wealthiest to rise. The top marginal tax rate increased from 35% to 39.6% for individuals making more than $400,000 and couples making more than $450,000. This marked a significant tax hike on top earners—the first such increase in nearly two decades—and it represented a pivot toward progressive tax reform.

A Closer Look at Tax Distribution

To appreciate the significance of recent tax policy changes, it's essential to understand the current distribution of federal income tax burdens.

• Top 10% of Earners: As of the latest data, individuals in the top 10% of income earners contribute approximately 71% of all federal income taxes, while earning about 48% of total adjusted gross income (AGI).

• Bottom 50% of Earners: Conversely, the bottom 50% of taxpayers pay only around 2% of the total federal income tax burden.

• Top 1% of Earners: The top 1%—those with incomes exceeding approximately $663,000—earn about 22.4% of total AGI and are responsible for 40.4% of all federal income taxes paid.

These figures highlight the progressive nature of the U.S. federal income tax system, where higher earners pay a disproportionately larger share of taxes. Even before the tax reforms of the Obama era, top earners were already contributing significantly to federal revenues.

Zero Federal Tax Liability for Many Americans

An equally important part of this story is what’s happening at the other end of the income spectrum. Nearly half of Americans paid no federal income tax at all, largely due to refundable tax credits and deductions such as the Earned Income Tax Credit (EITC), the Child Tax Credit, and education-related benefits. In many cases, individuals not only avoided paying taxes, but they also received refunds larger than the amount they paid in, effectively receiving income support from the government.

This approach is rooted in the concept of social equity and support for lower-income households, but it also complicates conversations around tax fairness. It underscores how the tax system serves not only to fund government services but also to redistribute wealth through the tax code itself.

Health Care Reform and Additional Tax Burdens

The fiscal cliff deal wasn’t the only policy initiative that increased tax obligations for high-income earners. The Affordable Care Act (ACA)—commonly known as Obamacare—also introduced several tax provisions specifically targeting wealthier Americans to help fund expanded health care coverage.

Key Tax Changes Under the ACA:

• 0.9% Medicare Surtax: This additional tax applies to wages, compensation, and self-employment income exceeding $200,000 for individuals and $250,000 for married couples filing jointly. It affects high earners who already contribute the standard Medicare tax but are now subject to this surtax on income above the threshold.

• 3.8% Net Investment Income Tax (NIIT): This applies to the lesser of a taxpayer’s net investment income or the amount by which their modified adjusted gross income exceeds the same thresholds ($200,000/$250,000). It targets income from capital gains, dividends, interest, rental income, and passive business activities.

Together with the increase in the top marginal income tax rate from 35% to 39.6% (implemented as part of the American Taxpayer Relief Act of 2012), these ACA-related provisions significantly increased the effective tax liability for the wealthiest Americans.

According to updated figures from the Tax Policy Center and IRS data as of 2024, the top 1% of earners—those with incomes averaging around $1.7 million in 2023—now face a combined federal tax burden exceeding 36% of their income when accounting for income taxes, payroll taxes, and ACA-related surcharges. This reflects a marked increase in their contribution to federal revenues compared to pre-ACA and pre-fiscal cliff levels.

Ongoing Debate and Economic Impacts

While these measures have generated substantial revenue, they’ve also sparked ongoing debates. Critics argue that high marginal tax rates may discourage investment and productivity among top earners, while supporters claim these provisions enhance fairness and fiscal sustainability by ensuring the wealthiest pay a proportionate share of national obligations.

The conversation around taxing high earners continues to evolve, with newer proposals—such as wealth taxes, minimum income taxes for billionaires, or expanded capital gains reforms—circulating in political circles as of 2025. These would build on the legacy of ACA-era changes to maintain or increase progressivity in the tax code.

Historical Context: Then and Now

It’s also instructive to examine how today’s tax burden compares with historical norms. Prior to the Tax Reform Act of 1986, high-income individuals had access to a variety of legal tax shelters, including real estate depreciation loopholes and preferential capital gains treatment, which allowed them to drastically reduce their effective tax rates.

Post-1986 reforms simplified the tax code and eliminated many of these shelters, thereby broadening the tax base but also making it harder for wealthy individuals to shield their income. In some ways, this made later increases in tax rates more impactful, since there were fewer legal avenues for avoiding taxes.

The Rising Share Paid by the Top 20%

As of 2025, the pattern remains consistent with earlier trends: families in the top 20% of income earners continue to shoulder a significant share of the federal tax burden. According to updated projections from the Congressional Budget Office (CBO), this group pays an average effective federal tax rate of approximately 27.2% of their income—reinforcing the narrative that higher earners fund a disproportionately large portion of government revenue.

Meanwhile, families in the bottom 20% typically receive more in federal tax credits and benefits than they pay in taxes. This results in a net negative tax liability, meaning many low-income households effectively gain more from the tax system than they contribute, through mechanisms like the Earned Income Tax Credit and the Child Tax Credit.

This reinforces the observation that the U.S. federal tax system, especially when including refundable tax credits, is one of the most progressive among developed nations.

The Politics of Taxation

The debate over whether the wealthy pay enough in taxes is largely ideological. Democrats and liberal economists argue that rising income inequality justifies more aggressive taxation of the wealthy. They point to research suggesting that economic growth has not been equitably distributed and that top earners are disproportionately benefiting from globalization and capital markets.

On the other side, Republicans and fiscal conservatives argue that high tax rates discourage investment, innovation, and job creation. They contend that the wealthy already pay more than their fair share and that government spending, not insufficient taxation, is the real issue driving deficits and national debt.

Notable Voices

President Obama captured the moral tone of the debate when he stated:

“I am prepared to do hard things and to push my Democratic friends to do hard things. But what I can’t do is ask middle-class families, ask seniors, ask students to bear the entire burden of deficit reduction when we know we’ve got a bunch of tax loopholes that are benefiting the well-off and the well-connected. It’s not fair. It’s not right.”

This view resonates with many Americans who believe that the tax code should be used to address economic disparities and ensure equal opportunity.

Speaker of the House John Boehner, however, offered a sharp contrast:

“Let’s make it clear that the president got his tax hikes on Jan. 1. This discussion about revenue, in my view, is over.”

This underscores a fundamental disagreement—not just over numbers, but over principles.

The Case for a Wealth Tax

Some economists and progressive thinkers believe that income taxes alone are insufficient to address wealth concentration. Income can be hidden, deferred, or minimized, but wealth is a more permanent marker of inequality.

Ronald I. McKinnon, a respected economist, suggested in a Wall Street Journal op-ed that the U.S. consider implementing a wealth tax. His plan would:

• Require all households to list domestic and foreign assets annually.

• Provide a $3 million exemption to protect the middle class.

• Impose a flat 3% tax on wealth above the exemption threshold.a

This would affect only the top 5% of households, but the implications would be profound. Critics argue that wealth taxes are difficult to enforce and can lead to capital flight, but proponents see it as a necessary evolution in tax policy.

International Comparisons

Many European countries have experimented with wealth taxes, with mixed results. France, for example, repealed its wealth tax in 2018 after it was blamed for driving high-net-worth individuals out of the country. However, countries like Norway and Switzerland still maintain versions of the tax.

The U.S., with its relatively low taxation of capital and wealth compared to Europe, remains an outlier. Proposals for wealth taxes are gaining traction, but implementation would face legal and logistical challenges.

The Future of Tax Policy

As the U.S. continues to grapple with rising deficits, an aging population, and economic inequality, the question of who should pay more is not going away. Future tax reforms may include:

• Adjustments to capital gains and dividend tax rates.

• Closing corporate loopholes and offshore tax havens.

• Reassessing deductions and exemptions for high earners.

• Broader adoption of consumption-based taxes (e.g., value-added taxes).

Each of these proposals comes with trade-offs. Striking a balance between revenue generation, economic growth, and social equity will remain the central challenge of U.S. tax policy.

Bottom Line

The data is unequivocal: upper-income Americans are bearing an increasingly large share of the nation’s tax burden. Through legislative changes like the fiscal cliff deal and provisions in the Affordable Care Act, the federal government has increased the tax liability of the wealthiest households significantly. These changes reflect shifting societal attitudes about fairness, responsibility, and economic justice.

However, the debate over taxation is far from settled. While many believe the rich should pay more, others caution against punishing success and undermining the very economic dynamism that has made the U.S. prosperous. Moving forward, this debate will shape not only tax policy but also the broader fabric of American democracy.
