Biden Budget Taxes: Details & Analysis

President Biden’s Fiscal Year 2024 Budget outlines several major tax increases that would bring U.S. tax rates far out of step with international norms. Some of the proposals may be familiar, recycled from prior budgets and failed legislative attempts, but some are new, like the proposed tax hikes for Medicare funding.

In total, they would add up to almost $4.7 trillion in new taxes targeted at businesses and high-income individuals. The major changes include higher marginal tax rates on corporate, individual, and capital gains income; a complicated new minimum tax on high-net-worth individuals; and increases to Medicare taxes. The negative effects of higher tax rates on saving, investment, and entrepreneurship would have economy-wide repercussions, ultimately harming workers, international competitiveness, and domestic investment.

The Biden budget would also expand and create several tax credits, including a one-year extension of the American Rescue Plan Act Child Tax Credit (CTC) and a permanent expansion of CTC refundability. The tax credits would offset the $4.7 trillion in gross taxes by about $900 billion, resulting in $3.8 trillion of net tax increases. After about $1 trillion of additional new spending on top of expanded tax credits, the FY2024 Budget would reduce the deficit by $2.8 trillion over the next decade

The Biden budget pays lip service to continuing at least some of the individual income tax cuts included in the 2017 Tax Cuts and Jobs Act (TCJA) that will expire after 2025, but offers no concrete proposal for doing so. As such, the cost of TCJA extensions is not factored into the budget. Nor is the cost of continuing the one-year expansion of the CTC. Together, such extensions would likely offset the projected deficit reductions.

The Biden budget would increase Internal Revenue Service (IRS) funding by 15 percent, or about $1.8 billion, to $14.1 billion in FY 2024. This includes $642 million for taxpayer services and $290 million for business systems modernization. The budget would also expand the drug pricing provisions enacted in the Inflation Reduction Act (IRA) by increasing the timeframe and number of drugs subject to government price setting. The budget proposes several major changes to the current international tax system that would move the U.S. closer to global minimum tax rules.

The Biden budget proposal would move top tax rates in the U.S. beyond international norms. The higher marginal tax rates on work, saving, and investment would reduce competitiveness and economic growth.

Under current law, the top combined marginal rate on individual income is 43.1 percent,  consisting of the top federal rate (37 percent) and the average of state and local income tax rates. Biden’s proposal would raise it to 45.7 percent by increasing the top rate from 37 percent to 39.6 percent.

The top combined marginal rate on capital gains income under current law is 29.1 percent, consisting of the 20 percent capital gains tax rate, the 3.8 percent Net Investment Income Tax (NIIT), and the average of state and local income tax rates on capital gains. Biden’s proposal would raise it to 49.8 percent by increasing the NIIT from 3.8 percent to 5 percent and taxing capital gains at ordinary income tax rates for taxpayers with more than $1 million in income. That would be the highest capital gains tax rate in the OECD (Organisation for Economic Co-operation and Development), currently levied by Denmark at 42 percent.

The top combined marginal rate on corporate income under current law is 25.7 percent, consisting of the federal corporate tax rate of 21 percent and the average percent state and local corporate income tax rate. Biden’s proposal would increase it to 32.2 percent—the second highest corporate tax rate in the OECD (behind Columbia at 35 percent)—by raising the corporate tax rate to 28 percent.

The combined integrated rate on corporate income reflects the two layers of tax corporate income faces: first at the entity level and again at the shareholder level. Under current law, it is 47.3 percent. Under Biden’s proposals, it would rise to a jaw-dropping 66.0 percent.

Biden Budget for FY 2024 Would Put Combined Marginal Tax Rates Further Above OECD Averages

	Current Law	FY 2024 Budget	OECD Average (Excluding U.S.)
Top Combined Marginal Rate on Individual Income	43.1%	45.7%	42.6%
Top Combined Marginal Rate on Corporate Income	25.7%	32.2%	22.8%
Top Combined Marginal Rate on Capital Gains Income	29.1%	49.8%	18.9%
Combined Integrated Rate on Corporate Income	47.3%	66.0%	41.4%
Note: Estimates include average state and local taxes. Sources: State and local tax statutes; OECD; Tax Foundation calculations.

The proposed Biden budget tax increases would put upward pressure on combined top tax rates at the state and local levels. For example, Biden’s FY 2024 Budget would yield combined top marginal rates in excess of 50 percent in five states and D.C.: New York (54.4 percent), Oregon (53.5 percent), California (52.9 percent), New Jersey (51.4 percent), Hawaii (50.6 percent), and D.C. (50.4 percent). Marginal rates would also exceed 50 percent in New York City (54.4 percent).
