Deteriorating Federal Budget to Run $1.4 Trillion Deficit in 2023, CBO Projects

4 min readBy: Erica York

The federal government is on track to run a $1.4 trillion deficit in fiscal year 2023, according to new projections from the Congressional Budget Office (CBO). Across the next decade (2024 through 2033), deficits will total more than $20 trillion, reaching an annual budget deficit of nearly $2.9 trillion in 2033. Completely balancing the budget over the next decade would be a tall order; instead, lawmakers should stabilize the fiscal situation while maintaining a competitive, pro-growth tax code and avoiding budget gimmicks.

The ongoing deficits are the result of a mismatch between government spending and taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. revenue, depicted in the table below. While revenue and spending as a share of GDP will meet or exceed their historical averages, spending growth outpaces revenue growth, leading to persistent deficits. Growing costs for interest, health-care programs, and Social Security drive the relative rise in spending.

In 2023, revenues will equal 18.3 percent of GDP, compared to a 50-year average of 17.4 percent, while spending will equal 23.7 percent of GDP, compared to a 50-year average of 20.1 percent. Interest costs will grow from 2.4 percent of GDP in 2023 to 3.6 percent of GDP over the next decade. Debt held by the public will reach its highest level ever recorded by 2033—118 percent.

The Congressional Budget Office (CBO) baseline assumes upcoming changes to tax and spending laws will occur as scheduled, including the expiration of nearly every aspect of the Tax Cuts and Jobs Act (TCJA) individual income tax changes. The TCJA expirations explain much of the anticipated jump in revenue from 2025 and 2027, boosting individual income taxAn individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns. The U.S. imposes a progressive income tax where rates increase with income. The Federal Income Tax was established in 1913 with the ratification of the 16th Amendment. Though barely 100 years old, individual income taxes are the largest source of tax revenue in the U.S. receipts by 0.8 percentage points as a share of GDP from 2025 to 2033. The expirations would also create a drag on economic growth. If, instead, lawmakers extend the TCJA individual income tax provisions, it would boost economic growth but further increase the deficit.

House Republicans have expressed the desire to balance the federal budget over the next decade. The Committee for a Responsible Federal Budget (CRFB) estimates doing so without tax increases would require an approximate 25 percent reduction in all government spending. Excluding certain programs, such as Social Security, Medicare, defense, and veterans, lifts the required cuts to 85 percent.

Similarly, closing the next decade’s budgetary gap without spending cuts would entail eye-popping tax increases with steep economic costs. Consider the following examples, modeled with the Tax Foundation’s Taxes and Growth model. Note the options are modeled under the previous baseline, running from 2023 through 2032, over which deficits will total $18.9 trillion.

  • Raising individual income tax rates by 50 percent across the board would increase revenue by $13.3 trillion from 2023 through 2032 on a conventional basis. From 2023 to 2025, the rates would range from 15 percent to 55.5 percent. From 2026 on, the rates would range from 15 percent to 59.4 percent. On a dynamic basis, it would raise about $9 trillion, as higher marginal tax rates on labor and capital discourage economic activity. Accordingly, long-run living standards would fall by 4.9 percent, measured by GDP.
  • Raising the corporate income taxA corporate income tax (CIT) is levied by federal and state governments on business profits. Many companies are not subject to the CIT because they are taxed as pass-through businesses, with income reportable under the individual income tax. rate to 35 percent, the rate that prevailed prior to the TCJA reforms, would increase revenue by $2.6 trillion from 2023 through 2032 on a conventional basis. On a dynamic basis, it would raise $2.1 trillion, as the higher marginal tax rateThe marginal tax rate is the amount of additional tax paid for every additional dollar earned as income. The average tax rate is the total tax paid divided by total income earned. A 10 percent marginal tax rate means that 10 cents of every next dollar earned would be taken as tax. on capital discourages investment. Accordingly, long-run living standards would fall by 1.5 percent, measured by GDP.

Even combined, the two examples would raise $15.8 trillion on a conventional basis, falling short of entirely closing the gap and coming at the expense of a 6.3 percent drop in long-run GDP. Accordingly, the combined revenue raised totals $10.9 trillion on a dynamic basis.

Adding base broadeners could raise additional revenue. For instance, combining the two tax increases with the elimination of the itemized deductionItemized deductions allow individuals to subtract designated expenses from their taxable income and can be claimed in lieu of the standard deduction. Itemized deductions include those for state and local taxes, charitable contributions, and mortgage interest. An estimated 13.7 percent of filers itemized in 2019, most being high-income taxpayers. s for mortgage interest and state and local taxes paid would raise $18.1 trillion from 2023 to 2032 on a conventional basis. In the long run, GDP would fall by 7.8 percent, and the combination would raise a smaller $11.9 billion on a dynamic basis.

Hiking marginal tax rates on labor and capital income cannot be reasonably relied upon to close the budget gap—and attempting to do so would jeopardize economic growth. Likewise, targeting tax increases at wealthy households, as President Biden’s proposed “billionaire minimum tax” does, would raise little revenue compared to significant administrative and economic trade-offs.

The CBO report warns the coming decade will be one fraught with budget challenges, including rising deficits, growing interest costs, and expiring tax provisions. Immediately balancing the $20 trillion budget shortfall would take drastic, unwanted policy changes. It’s an unrealistic goal. Instead, lawmakers should target a more achievable goal, such as stabilizing debt and deficits with an eye toward comprehensive tax reform that can produce sufficient revenue with minimal economic harm.
