Senator Elizabeth Warren has proposed a wealth tax equal to 2 percent of net worth above $50 million and 6 percent of net worth above $1 billion, which her campaign estimates would raise $3.75 trillion over 10 years.
PWBM estimates that the proposal would raise about $2.7 trillion over fiscal years 2021-2030, not including macroeconomic effects. Including macroeconomic effects, PWBM estimates that the proposal would raise about $2.3 trillion over the same period.
PWBM projects that the proposal would reduce GDP by 0.9 percent in 2050 under the standard budget scoring convention that additional revenues reduce the deficit. If the revenues were instead spent on public investments, PWBM projects GDP in 2050 would fall between 1.0 and 2.1 percent, depending on the productivity of the investment. Average hourly wages in the economy in 2050, including wages earned by households not directly subject to the wealth tax, would fall between 0.8 and 2.3 percent due to the reduction in private capital formation.
We estimate the budgetary and economic effects of increasing the top rate on long-term capital gains and qualified dividends from 20 percent to 24.2 percent, which is enacted on January 1st, 2021. We project that it will raise around $60 billion of additional revenue on a conventional basis over the 10-year budget window and increase GDP by 0.1 percent by 2050.
We estimate the budgetary and economic effects of a new broad-based 1 percent value-added tax (VAT) with a progressive universal rebate calculated based on earnings, which is enacted on January 1st, 2021. We project that it will raise $700 billion of additional revenue on a conventional basis over the 10-year budget window and increase GDP by 0.8 percent by 2050.
We estimate the budgetary and economic effects of a new carbon tax of $30 per ton of emissions, which is enacted on January 1st, 2021, rising by inflation plus 5 percent through 2050. We project that it raises $1.6 trillion of additional revenue on a conventional basis over the 10-year budget window and increases GDP by 2.2 percent by 2050.
We analyze the budgetary and economic effects of three very different illustrative policy bundles that reduce federal budget deficits over time without shrinking the economy relative to current law with rising debt. The results also demonstrate how federal debt falls short of measuring the true fiscal burden being shifted to future generations.

We report estimates from the Penn Wharton Budget Model (PWBM) that exempting employment-based green cards from statutory limits for applicants (and their families) who have earned a doctoral or master’s degree in a STEM field---similar to Section 80303 in H.R. 4521---would reduce federal budget deficits by $129 billion from 2025 to 2034. In contrast, a conventional budget estimate, which would include projected increases in federal spending but not the effect of a larger population on federal tax revenues, shows an increase in federal deficits of $4 billion.
PWBM estimates that exempting from immigrants with advanced STEM degrees from numerical limitations on green cards would reduce deficits by $129 billion over the 2025-2034 period and by $634 billion over the 2035-2044 period.
PWBM estimates that---even under myopic expectations---financial markets cannot sustain more than the next 20 years of accumulated deficits projected under current U.S. fiscal policy. Forward-looking financial markets are, therefore, effectively betting that future fiscal policy will provide substantial corrective measures ahead of time. If financial markets started to believe otherwise, debt dynamics would “unravel” and become unsustainable much sooner.
Debt ceiling debates would become less frequent if Congress adopted fiscal measures that limited the growth of federal government debt relative to the size of the economy. Without changes in fiscal policy, we project that the debt-to-GDP ratio will grow from 100 percent in 2024 to 190 percent in 2050. Contrary to conventional thinking, there exists a wide range of policy options that can reduce the growth of debt while growing the economy.
PWBM estimates that Title I of the Build It in America Act would add $76 billion to the budget deficit over the next decade and reduce deficits by $18 billion during the subsequent second decade. It would temporarily boost business investment and GDP during the next two years while lowering GDP in subsequent years. If lawmakers made the extensions permanent, the budgetary cost would rise to $1.25 trillion over the next two decades and GDP would largely remain unchanged, as the tax incentive effects and debt effects mostly offset.
We estimate the Fiscal Responsibility Act (“FRA”) of 2023 will reduce noninterest spending by $1.3 trillion over the 10-year budget window using standard scoring assumptions. If discretionary spending in Fiscal Year 2026, after sequestration is no longer in effect, deviates from standard scoring assumptions, the spending reduction could be as low as $234 billion or as high as $1.8 trillion.
The deadline to raise the nation’s debt ceiling is closer than previously thought because tax receipts in April fell below projections. PWBM estimates that receipts are running $150 billion below government projections for fiscal year 2023, most likely due to a decline in capital gains income and weakening corporate profit margins.
Several revenue and spending provisions in The Tax Cuts and Jobs Act (TCJA) are scheduled to expire (“sunset”) by the end of 2025. We estimate that “extenders” (“no sunset”) would increase the federal debt held by the public from 226.0 percent of GDP to 261.1 percent of GDP by 2050.
We estimate President Biden’s newly proposed Income-Driven Repayment (IDR) Plan will cost between $333 to $361 billion over the 10-year budget window, more than twice as much as the cost estimate released by the Biden Administration. These costs are in addition to the one-time cost of direct loan forgiveness that we previously estimated at $469 billion.
Under current law, we project that national debt will rise to 225% of GDP by 2050 and continue to rise thereafter. Changing demographics will reduce future economic growth.
President Biden’s new student loan forgiveness plan includes three major components. We estimate that debt cancellation alone will cost up to $519 billion, with about two-thirds of the benefit accruing to households making $88,000 or less. Loan forbearance will cost another $16 billion. The new income-driven repayment (IDR) program would cost another $70 billion, increasing the total plan cost to $605 billion under strict “static” assumptions. However, depending on future IDR program details to be released and potential behavioral (i.e., “non-static”) changes, total plan costs could exceed $1 trillion.
We estimate that forgiving federal college student loan debt will cost between $300 billion and $980 billion over the 10-year budget window, depending on program details. About 70 percent of debt relief accrues to borrowers in the top 60 percent of the income distribution.
PWBM estimates that the Senate-passed version of the Inflation Reduction Act would reduce non-interest cumulative deficits by $264 billion over the budget window. The impact on inflation is statistically indistinguishable from zero. GDP falls slightly within the first decade while increasing slightly by 2050. Most, but not all, of the tax increases fall on higher income households.
PWBM and CBO find an almost identical impact of the Inflation Reduction Act of 2022 (“IRA”) on the budget, with small differences stemming from the timing of the corporate minimum tax revenue. The impact on inflation is statistically indistinguishable from zero for either estimate.
PWBM estimates that the Inflation Reduction Act would reduce non-interest cumulative deficits by $248 billion over the budget window with no impact on GDP in 2031. The impact on inflation is statistically indistinguishable from zero. An illustrative scenario is also presented where Affordable Care Act subsidies are made permanent. Under this illustrative alternative, the 10-year deficit reduction estimate falls to $89 billion.

We estimate that the U.S. federal government faces a permanent fiscal imbalance equal to over 10 percent of all future GDP under current law where future federal spending outpaces tax and related receipts. Federal government debt will climb to 236 percent of GDP by 2050 and to over 800 percent of GDP by year 2095 (within 75 years).
We estimate that each new preschooler for a universal pre-K program requires about $21,000 in new construction costs for facilities expansion. Including non-construction costs, a universal pre-K program for three- and four-year-olds will cost about $351 billion over the 10-year budget window. If made permanent after 10 years, this program will have essentially no impact on long-run GDP. A pre-K program for just four-year-olds reduces the 10-year cost to $196 billion and slightly increases long-run GDP, if that program is made permanent.
