U.S. Representative Josh Gottheimer (D-NJ) speaks during a press conference about the SALT Caucus outside the United States Capitol on Wednesday February 08, 2023 in Washington, DC. As debates ramp up for President Donald Trump's policy agenda, changes to a key tax provision could benefit higher earners, experts say. Enacted via the Tax Cuts and Jobs Act, or TCJA, of 2017, there's a $10,000 limit on the federal deduction on state and local taxes, known as SALT, which will sunset after 2025 without action from Congress.

Currently, if you itemize tax breaks, you can't deduct more than $10,000 in levies paid to state and local governments, including income and property taxes. Raising the SALT cap has been a priority for certain lawmakers from high-tax states like California, New Jersey and New York. With a slim House Republican majority, those voices could impact negotiations.

Lawmakers have floated several updates, including a complete repeal, which seems unlikely with a tight budget and several competing priorities, experts say.
