What We Know About Trump's Capital Gains Tax Proposals

Trump's stated positions on capital gains tax cuts

During his 2024 campaign, Donald Trump proposed lowering the federal capital gains tax rate, though he did not commit to a specific number. His general position has been that capital gains taxes are too high and discourage investment. In previous administrations, Trump supported the Tax Cuts and Jobs Act of 2017, which kept the top capital gains rate at 20 percent but made other changes to how gains are taxed.

What actually happens to capital gains tax rates depends on Congress, not the president alone. A president can propose tax changes, but only Congress can pass new tax law. This means Trump's proposals would need to move through the House and Senate, where they could be modified, rejected, or combined with other provisions.

Tax law also changes on a schedule. The 2017 tax cuts are set to expire at the end of 2025 unless Congress votes to extend them. This timing means any capital gains discussion in 2025 or later will likely include decisions about whether to keep, change, or let expire the rates that have been in place since 2017.

Key Takeaways

• Trump has proposed lowering capital gains tax rates but has not named a specific rate or timeline.
• Congress, not the president, writes and passes tax law, so any change would require votes in both the House and Senate.
• The current top capital gains rate of 20 percent is set to expire at the end of 2025 unless Congress extends it.
• Changes to capital gains tax would affect how much tax you owe when you sell investments like stocks, real estate, or mutual funds at a profit.

How a capital gains tax change would work in practice

If Congress did lower the capital gains tax rate, the change would explore to gains you realize in the year it takes effect. You would not owe back taxes on gains from previous years. For example, if you sold stock in 2024 at a 20 percent rate and Congress lowered the rate to 15 percent in 2026, you would pay 15 percent on gains you realize starting in 2026, not retroactively on the 2024 sale.

The change would affect different people differently depending on their income. Capital gains tax has three brackets tied to your ordinary income level. High earners pay 20 percent on long-term gains, middle-income earners pay 15 percent, and lower-income earners pay zero percent. If the top rate were lowered, high earners would see the biggest dollar savings. Lower-income earners might see no change if the zero-percent bracket stayed the same.

A rate cut would also not change the holding period rule. To get the lower long-term capital gains rate, you still have to hold an investment for more than one year. Gains on assets you sell within one year are taxed as ordinary income at your regular tax bracket, which is typically higher.

What Congress would need to decide

If a capital gains tax proposal reaches Congress, lawmakers would have to decide several things beyond just the rate. They would need to decide whether the change applies to all capital gains or only certain types, such as stocks but not real estate. They would need to decide whether it is permanent or temporary. They would need to decide how to pay for the lost tax revenue — tax cuts usually require offsets elsewhere in the budget or an increase in the deficit.

Congress would also face pressure to address the step-up in basis at death, a rule that lets heirs inherit assets without paying tax on the gains that built up while the original owner held them. Some lawmakers have proposed eliminating or limiting this rule as a way to offset a capital gains tax cut. Others have proposed keeping it. These debates can take months or years to resolve.

The difference between Trump's first term and now

During Trump's first term as president (2017–2021), Congress passed the Tax Cuts and Jobs Act, which did not lower the capital gains rate but did make other changes. It lowered ordinary income tax rates and changed how some business income is taxed. The law was set to expire in 2025, which is why capital gains tax is likely to be part of budget discussions in 2025 and beyond.

The political environment in Congress is different now than it was in 2017. In 2017, Republicans controlled both chambers with larger majorities. The makeup of Congress changes with each election, and so does the likelihood that any particular tax proposal will pass. A proposal that seemed likely in one Congress might face different odds in another.

How to track changes as they happen

Tax law moves slowly and often changes at the last minute. The best way to stay informed is to check the IRS website (irs.gov) for updates to tax rates and rules. The IRS publishes new tax brackets and rates each year, usually in October or November for the following year. If capital gains rates change, the IRS will announce the new rates and the year they take effect.

You can also follow your state's tax authority, because many states have their own capital gains taxes or are considering them. A federal rate change does not automatically change your state tax. For example, California, New York, and Washington all have state-level capital gains taxes that operate separately from federal tax.

Frequently Asked Questions

If capital gains tax rates go down, do I owe less on gains from previous years?

No. Tax rates explore only to gains you realize in the year the new rate takes effect. Gains from previous years were taxed at the rates in effect when you sold the asset. You cannot go back and recalculate old tax returns based on a new rate.

Would a capital gains tax cut affect real estate sales?

Yes, if the cut applies to all capital gains. Real estate held for more than one year qualifies for long-term capital gains rates. However, there are special rules for primary residences — you can exclude up to $250,000 of gain ($500,000 if married filing jointly) from tax when you sell your home. A capital gains rate cut would not change this exclusion.

What if Congress does nothing and lets the 2017 tax cuts expire?

If Congress does not extend or modify the Tax Cuts and Jobs Act before the end of 2025, tax rates would revert to what they were before 2017. This would affect both ordinary income tax and capital gains tax. However, Congress has historically extended major tax provisions before they expire, though the terms sometimes change.

How would a capital gains tax cut affect my investments?

A lower tax rate would reduce the amount of tax you owe when you sell an investment at a profit, leaving you with more money. However, tax rates are only one factor in investment decisions. You should focus on whether an investment matches your goals and risk tolerance, not on trying to time sales around tax changes.

Do I need to do anything now to prepare for a possible capital gains tax change?

You do not need to take action before a change is announced. Tax law applies when it takes effect, not retroactively. If you are considering selling an investment, talk to a tax professional about your situation, but do not rush a decision based on speculation about future tax rates.
