Under current law, the 2017 Tax Cuts and Jobs Act (TCJA) will expire at the end of 2025, raising personal income tax rates back to 2017 levels. Some lawmakers propose extending the TCJA but with higher rates for high-income households. We consider three options.
Treasury data through April 28 shows that tax receipts are broadly in line with government projections made earlier this year, before the downsizing of the IRS was announced. Receipts from tariffs have significantly exceeded projections.
Many trade models fail to capture the full harm of tariffs. PWBM projects Trump’s tariffs (April 8, 2025) will reduce long-run GDP by about 6% and wages by 5%. A middle-income household faces a $22K lifetime loss. These losses are twice as large as a revenue-equivalent corporate tax increase from 21% to 36%, an otherwise highly distorting tax.
We evaluate two immigration policies that shift 10 percent of future low-skilled immigration toward either: (i) high-skilled immigrants (“ HSI ”) that otherwise maintains the current share of STEM workers within the high-skilled group, or (ii) only high-skilled STEM workers (“ HSI STEM ”) that increases the share of STEM relative to other high-skill workers. The number of total immigrants remains the same under both policies. Both policies grow the economy, reduce federal debt, and increase wages across all income groups: lower-skilled, higher-skilled non-STEM workers, and higher-skilled STEM workers. In fact, this policy change affords the rare opportunity of a “Pareto improvement” benefitting all groups.

Cohabitation rates have increased significantly during the last two decades. Cohabiting individuals appear to have weaker workforce engagement and earnings. With changing U.S. demographics, the trend toward favoring cohabitation over marriage appears likely to continue.
Eliminating taxes on Social Security benefits reduces incentives to save and work while increasing federal debt. Wages and GDP fall over time. The policy primarily benefits high-income households nearing or in retirement while harming households under thirty and all future generations across the entire income distribution.
Treasury debt held by the public is an explicit pay-as-you-go obligation. The government also runs implicit pay-as-you-go obligations, such as Social Security and Medicare Part A, which are twice as large. Both types of obligations require tax increases and spending cuts to balance the budget over time.
The deduction for pass-through income under section 199A provides a benefit in excess of 20 percent (“excess benefit”) for some taxpayers due to its interaction with the progressive tax rate system. As Congress considers extending 199A beyond 2025, options to remove the excess benefit while maintaining the 20 percent tax benefit could raise between $46B and $178B over the 10-year budget window, depending on design.
A package of 13 major tax and spending reforms, based on standard public economics design principles, is shown to reduce federal debt, increase social insurance, and expand the economy more than any previously analyzed policies by PWBM.
