Key takeaways
- Billionaires pay an average effective tax rate of around 23%–25%. This reflects the top 400 wealthiest Americans, but rates vary dramatically even among the ultra-rich.
- Middle-class households typically pay 10–15% in federal income taxes, or about 24–28% when including all federal, state, and local taxes.
- The gap between billionaire and middle-class tax rates exists largely because much of billionaire wealth comes from unrealized capital gains, which aren’t taxed until assets are sold.
- Corporate tax cuts, pass-through business structures, and borrowing against assets all help reduce taxable income for the ultra-wealthy.
- While billionaires contribute enormous sums in absolute dollars, their share of total income paid in taxes has declined over the past decade.
- Policy proposals like a minimum billionaire tax, wealth taxes, or higher capital gains rates aim to close this gap.
- The world’s billionaires often make headlines for their immense wealth, but just how much of that wealth goes to taxes? It’s a question that sparks debate, shapes tax policy, and influences how people view fairness in the economy. While billionaires face some of the highest marginal tax rates on paper, studies show their effective tax rates, what they actually pay, are often far lower than those of average Americans.
This article explains how billionaires are taxed, why their effective tax rates differ, what the data shows about their real contributions, and how tax policy changes continue to affect what they pay.
Understanding Billionaire Taxation
Before exploring how much billionaires pay in taxes, it’s important to understand how the U.S. tax system works, and how the ultra-wealthy earn and report income differently from most people.
What Is a Tax Bracket and an Effective Tax Rate?
A tax bracket is the range of income taxed at a specific rate. In the U.S., the tax system is progressive, meaning that higher portions of income are taxed at higher rates. For example, as of 2025, the top marginal income tax rate is 37% for individuals earning over $626,351.
However, this does not mean someone in that bracket pays 37% of their total income in taxes. Each income segment is taxed at different rates, and deductions further reduce taxable income.
That’s where the effective tax rate (ETR) comes in. The effective rate represents the percentage of total income actually paid in taxes. It provides a clearer picture of someone’s true tax burden.
For most middle-class households, the effective federal income tax rate falls between 10% and 20%. For billionaires, surprisingly, research finds it can be around 20% to 25%, despite their vast wealth.
What Counts as Income for the Ultra-Wealthy?
For most Americans, income comes from wages, salaries, and bonuses- money earned through work. For billionaires, it’s slightly more complex.
Billionaires often make money through:
- Capital gains: Profit from selling assets such as stocks, businesses, or real estate.
- Dividends: Payments from investments.
- Business ownership: Income from corporations, partnerships, or trusts.
- Wealth appreciation: Increases in the value of assets they haven’t sold (known as unrealized gains).
Since unrealized gains aren’t taxed until assets are sold, much of a billionaire’s wealth growth remains untaxed year after year. This difference in how income is defined and recognized is key to understanding why their effective tax rates are often lower.
What the Data Shows: How Much Do Billionaires Really Pay?
Recent research gives a clearer picture of how much billionaires actually pay in taxes, and how those rates compare to other groups.
Understanding Different Tax Rate Calculations: Why Numbers Vary
Before comparing billionaire tax rates, it’s important to understand why studies often report very different numbers. The variation comes down to how “income” and “taxes paid” are defined.
- Traditional Effective Tax Rate (23–26% range): This is the standard measure used by most researchers. It counts only realized income—money that billionaires actually receive and report to the IRS, such as wages, dividends, business income, and capital gains from sold assets.
- Wealth-Based Effective Rates (8–10% range): Some analyses include unrealized gains—wealth increases from stock or business growth not yet sold. For example, a $1 billion portfolio gain counts as income under this method, even if nothing is sold, producing much lower rates. Critics note this isn’t current law, while supporters say it shows how billionaires access wealth without paying taxes.
- Global Tax Burden (44–60% range): A third approach adds up all taxes tied to billionaire-owned corporations—like U.S. and foreign corporate taxes, estate taxes, and state, local, and payroll taxes. Using this method, the richest 0.0002% face a total tax burden of 44–60% of their income, since they are considered to share in their companies’ tax payments.
Key Findings from the Latest Studies
- The top 400 wealthiest Americans, roughly the richest 0.0002% of the population, paid an average effective tax rate of about 23.8% from 2018–2020.
- By comparison, the overall U.S. population had an average tax rate of around 14.5%, or roughly 24-28% when all federal, state, and local taxes were included.
- The top 0.01% of income earners (not just billionaires) paid around 25%, down from roughly 30% a decade earlier.
In other words, while billionaires often face top statutory tax rates on paper, their actual share of income paid in taxes has declined over time.
Why Billionaire Tax Rates Have Fallen
There are several reasons billionaire tax rates have decreased in recent decades:
- Corporate tax cuts: The 2017 Tax Cuts and Jobs Act (TCJA) lowered the corporate income tax rate from 35% to 21%. Because many billionaires earn income through corporations, this dramatically reduced their overall burden.
- Growth of unrealized wealth: Much of billionaire wealth growth now comes from stock appreciation and private company valuations; forms of income that aren’t taxed until realized.
- Increased use of pass-through entities: Many ultra-rich individuals earn business income through LLCs or partnerships, which can report negative taxable income while still being profitable on paper.
- Declining estate and gift tax impact: The effective estate tax rate is approximately 0.6–0.8% of wealth for married decedents and can reach up to about 7% for single decedents.
These factors, combined with sophisticated tax planning, have pushed billionaire effective tax rates well below those faced by high-income wage earners.
Comparing Billionaire Tax Burdens to Other Groups
To grasp the scope of the disparity, it helps to compare billionaire tax burdens with those of other income levels.
Billionaires vs. High-Income Earners
High-income wage earners, such as executives, doctors, and lawyers, often pay effective tax rates of 35% to 45%, including payroll taxes and state taxes. They receive most of their income as salaries, which are taxed immediately and at higher marginal rates.
By contrast, billionaires often derive most of their wealth from assets, which are taxed at much lower capital gains rates (currently up to 20%) and only when sold. This means that, proportionally, many billionaires pay lower effective rates than top-earning professionals.
Billionaires vs. the Average Taxpayer
The average U.S. household pays an overall effective tax rate of about 30% when accounting for income, payroll, and state taxes. That’s roughly 6 percentage points higher than the average for the top 400 billionaires.
In other words, while billionaires pay enormous sums in absolute dollars, the percentage of their income that goes to taxes can be lower than that of many middle-class families.
Why Do Billionaires Pay Lower Effective Tax Rates?
Understanding the mechanics behind billionaire taxation helps explain why their effective rates are so low compared to their incomes. It’s a common misconception that billionaires all pay similar tax rates. In reality, there is enormous variation—even among people with similar incomes. Yale University’s Budget Lab shows that within the top 1% of earners, effective tax rates range from 3% to 45%. About 80% of high-income filers fall between 16% and 37%, but others face far higher or lower rates depending on how their income is structured.
Income Source Determines Tax Burden
Two billionaires with identical net worths can have vastly different tax bills. For example:
- Wage-heavy billionaires (e.g., CEOs taking large salaries) may pay 37–45% when payroll and state taxes are included.
- Investment-heavy billionaires—whose wealth comes primarily from stock appreciation—may pay 0–20% depending on whether they sell shares.
- Business-structure billionaires using partnerships or LLCs may legally report negative taxable income, even while becoming richer.
The Partnership Advantage
Structuring income through partnerships and LLCs can significantly reduce the tax burden by:
- Deducting business losses
- Passing business tax credits to personal returns
- Avoiding the 3.8% Net Investment Income Tax through “active participation” designations
- Shifting assets between entities without triggering tax events
For example, $2 million in wage income would generate roughly $695,000 in federal taxes. The same amount run through a partnership can reduce the tax bill to under $200,000 through legal deductions.
The Role of Business Structures
Many billionaires own companies through pass-through entities, such as limited liability companies (LLCs) or S-corporations. These structures allow profits (or losses) to “pass through” to the owner’s personal tax return.
However, some businesses report negative taxable income by using accounting techniques like depreciation and loss carryforwards, even when the company is profitable in reality. Research found that for the top 400 wealthiest Americans, pass-through business income was negative on average from 2010–2020, effectively reducing their tax liabilities.
Corporate Tax Allocation
Billionaires who hold large shares in corporations indirectly bear part of the corporate tax burden. When corporate tax rates fell from 35% to 21% in 2017, the taxes attributed to these owners dropped sharply.
According to researchers, this corporate tax reduction alone accounted for about 9 percentage points of the decline in effective tax rates for the wealthiest individuals between 2010 and 2020.
Estate Taxes and Charitable Deductions
Estate and gift taxes play a minimal role in billionaire taxation today. The share of total taxes paid from these sources is less than 1% of billionaire economic income.
Charitable donations, however, can make a notable difference. When including the value of charitable contributions as a “voluntary tax,” the effective rate for the top 400 rises from roughly 24% to about 35%. Still, those contributions are discretionary and often serve both philanthropic and tax-planning purposes.
Unrealized Wealth and Borrowing
Another common strategy among billionaires is borrowing against assets instead of selling them. For instance, if a billionaire needs $100 million in liquidity, they can take out a loan secured by their stock holdings. Loans aren’t taxable, so they can maintain their lifestyle without triggering capital gains taxes.
This “borrow-don’t-sell” strategy allows wealth to grow untaxed while avoiding realized income. It’s a key reason effective tax rates at the top remain far below statutory rates.
Why Billionaire Taxation Matters
The question of how much billionaires pay in taxes isn’t just about numbers; it’s about fairness, public trust, and the design of the entire tax system.
Revenue and Fiscal Policy
When the wealthiest individuals pay lower effective rates, governments collect less revenue relative to economic growth. That can limit funding for infrastructure, education, and public services, or shift the tax burden to middle-income households.
According to estimates from the Congressional Budget Office, closing high-end loopholes or adding a small tax on unrealized gains could raise hundreds of billions in revenue over a decade, without changing top marginal rates.
Policy Options on the Table
Several ideas have been proposed to address the gap between paper tax rates and real-world outcomes for billionaires:
- Minimum billionaire tax: Some proposals call for a minimum effective tax of 20% on total income, including unrealized gains, for households worth over $100 million.
- Wealth taxes: A small annual tax (e.g., 1–2%) on net worth above a certain threshold could capture wealth growth that currently escapes taxation.
- Higher capital gains rates: Aligning capital gains with income tax rates would reduce the advantage of earning through investments rather than wages.
- Closing pass-through loopholes: Limiting deductions and loss offsets that allow profitable companies to report negative taxable income.
Each approach has trade-offs; balancing fairness, efficiency, and economic competitiveness. Policymakers continue to debate which path best aligns with long-term fiscal and social goals.
Limitations and the Challenge of Measuring Billionaire Taxes
It’s important to note that measuring billionaire taxes precisely is difficult. The IRS does not publicly disclose individual taxpayer data, and much of billionaire wealth is held in private assets.
Researchers rely on estimates that combine tax filings, Forbes wealth rankings, and corporate records. While recent studies represent the most comprehensive efforts yet, they still face limitations, such as:
- Incomplete reporting: Some offshore assets or trusts may be excluded.
- Timing effects: One-time realizations or losses can skew short-term rates.
- Valuation uncertainty: Privately held companies are hard to value accurately.
These challenges mean that effective tax rate estimates should be viewed as best approximations rather than exact figures. Still, they provide valuable insight into broad trends in how wealth and taxes interact.
The Future of Billionaire Taxation
As the gap between paper tax rates and effective rates continues to widen, lawmakers are re-evaluating how to ensure the wealthiest Americans pay their fair share.
Several key developments to watch include:
- Post-2025 tax reforms: Many provisions of the 2017 Tax Cuts and Jobs Act are set to expire, potentially increasing top rates unless extended.
- Global minimum tax frameworks: The OECD’s ongoing work could influence individual and corporate taxation across borders.
- IRS enforcement funding: Increased resources for auditing high-income taxpayers may improve compliance and data accuracy.
- New valuation and reporting rules: Future policies could require more transparent reporting of asset values and unrealized gains.
Regardless of policy direction, billionaire taxation will remain a focal point in debates over fiscal responsibility, and economic fairness in the years ahead.
So, how much do billionaires pay in taxes?
According to the most detailed data available, U.S. billionaires pay an average effective tax rate of about 23% to 25%; lower than the rate paid by many middle-class families and far below the top statutory rate of 37%.
This gap stems from how wealth is generated and taxed: through unrealized gains, business structures, and policy choices that allow deferral or reduction of taxable income.
While billionaires contribute enormous sums in absolute dollars, the share of their income subject to tax is shrinking; raising important questions about fiscal sustainability, and what a “fair share” really means in a modern economy.
Frequently Asked Questions
Why are billionaire tax rates lower than average taxpayers?
Their wealth is largely in investments and unrealized gains, which are taxed only when sold, and they use structures like LLCs or corporations that reduce taxable income.
How do corporate tax cuts affect billionaire taxes?
Reductions in corporate tax rates lower the overall tax burden on billionaire-owned businesses, indirectly reducing the effective taxes owed by individual shareholders.
Can billionaire taxes be increased?
Yes, policymakers propose options like minimum taxes, wealth taxes, or higher capital gains rates to ensure billionaires pay a larger share of their income.
Why is measuring billionaire taxes difficult?
Accurate measurement is challenging due to private holdings, unrealized gains, offshore assets, and the lack of publicly available individual tax data.
