Sen. Bernie Sanders’ proposal for an annual tax on billionaire wealth could have meant an estimated $11 billion tax bill for Jeff Bezos under the valuation used when the legislation was introduced. That figure is an illustration from Sanders’ office, not a tax assessment or a payment Bezos has made.
Sanders and Rep. Ro Khanna introduced the Make Billionaires Pay Their Fair Share Act on March 2, 2026. It would impose a 5% annual tax on the net value of assets held by a person or trust whose wealth exceeds $1 billion. The proposal remains legislation under consideration; it is not current tax law.
Where the $11 Billion Figure Comes From
At the bill’s introduction, Sanders’ office estimated Bezos’ net worth at $218 billion. Five percent of $218 billion is $10.9 billion, which the office rounded to approximately $11 billion.
That calculation depends on the value assigned to Bezos’ assets at a particular time. His wealth is not a fixed bank balance. Estimates can change as the values of company shares and other holdings change. The actual amount owed, if Congress enacted the bill, would depend on the law’s final text and the valuation rules applied to his assets.
The bill would tax the full net value of an eligible taxpayer’s assets at 5%, rather than only the amount above $1 billion. It would direct the Treasury Department to establish methods for valuing assets, including holdings whose value cannot easily be observed in a market.
What Sanders Wants the Revenue to Fund
Sanders and Khanna say the tax would help pay for a first-year affordability rebate of $3,000 per eligible person, including qualifying dependents, in households meeting the proposal’s income rules. Their broader plan includes health care, housing, child care, teacher pay and home care measures.
Economists Emmanuel Saez and Gabriel Zucman estimated that the tax could raise about $4.4 trillion over a decade. Their analysis used an estimate of 938 American billionaires with combined wealth of about $8.2 trillion at the start of 2026. It assumed that avoidance and evasion would reduce collections by 10%.
Those numbers are forecasts based on assumptions. They are not money the government has collected or a guarantee of what it would collect if the bill passed.
Why Economists Disagree
The Tax Foundation, which analyzed the proposal separately, argues that taxpayers could respond more strongly to an annual wealth tax than Saez and Zucman assumed. Using a higher avoidance assumption, it estimated revenue of about $3.3 trillion over 10 years.
The disagreement matters because the tax would cover assets that may be difficult to value, including privately held businesses. The bill proposes reporting requirements and audits to enforce the tax, but the size of future collections would remain uncertain until a tax was implemented and assessed.
Supporters see the proposal as a way to fund services and reduce the concentration of wealth. Critics question its effects on investment, its administrative demands and whether it would raise the projected amount. Neither side’s forecast establishes that the proposal would, by itself, repair or damage the overall U.S. economy.
What Happens Next
The Senate bill was introduced and referred to the Senate Finance Committee. It would need to advance through Congress and be signed into law before anyone owed tax under it.
For now, the accurate takeaway is narrower than the claim on the graphic: Sanders’ office estimated that Bezos would have owed roughly $11 billion using its March valuation and the proposed 5% rate. Whether the plan becomes law, how much it would collect and how it would affect the economy remain open questions.
