President Trump is considering a proposal to index capital gains taxes for inflation and increase the amount of home sale profits exempt from taxation. The plan aims to address housing supply shortages and lower costs for homeowners by reducing the tax burden associated with selling property.
Current federal tax law allows single filers to exclude up to $250,000 in profit from a home sale, while married couples can exclude $500,000. These thresholds were established in 1997 and have not been adjusted since, despite median home prices nearly tripling during that period. Michael Faulkender, co-chairman of the America First Policy Institute’s Center for American Prosperity, reports that 34% of homeowners now exceed the $250,000 cap, a figure projected to reach 70% by 2035.
The proposal would also index the original purchase price of assets like stocks and personal property for inflation. This change would mean taxpayers only pay capital gains tax on "real gains" rather than value increases driven by inflation. Proponents argue this would mirror other parts of the tax code, such as income tax brackets and Social Security benefits, which are already adjusted for inflation.
The scale of the current housing challenge involves an estimated shortage of nearly 5 million units. By raising the exclusion limits and indexing for inflation, the administration seeks to address the "lock-in effect," where owners avoid selling to prevent triggering capital gains taxes. This shift is intended to help first-time homebuyers, who reached a median age of 40 in 2025, by increasing the availability of existing housing inventory. The policy would also alter how individual investors calculate tax liabilities on various assets, potentially changing day-to-day decisions regarding when to sell stocks or property.
Critics of the policy typically argue that such tax cuts reduce government revenue and primarily benefit wealthier individuals. However, historical data cited in the report suggests that past reductions in capital gains rates—such as the 1981 cut from 28% to 20% and the 2003 cut to 15%—were followed by significant increases in tax realizations. While the administration is reportedly floating these ideas, specific dates for formal legislation or effective implementation have not been reported. Moving forward, the proposal would likely require Congressional action to amend the tax code established in 1997.
