SALT Cap Increase? What to Expect in 2025 Tax Reform

Some lawmakers say it’s past time to increase the $10,000 cap on state and local tax deductions, and President Trump seems to agree.

Discussions about the state and local tax deduction (SALT) are back.

One reason? Lawmakers are negotiating 2025 tax reform since Republicans control the White House, and both chambers of Congress, President Trump, and several GOP lawmakers would like to see adjustments to the SALT cap.

  • The SALT deduction allows taxpayers who itemize to deduct state and local taxes from their federal taxable income.
  • The deduction was capped at $10,000 by the Tax Cuts and Jobs Act (TCJA), ushered in by Donald Trump in his first stint as president.
  • Since then, the SALT cap has been a point of contention for many in high-tax states who argue the deduction limit disproportionately affects them.

But it’s important to note that the state and local tax deduction isn’t just an issue for people in so-called “blue states.”

Several Republican lawmakers have said they won’t support 2025 tax reform that doesn’t significantly lift the cap, while the U.S. House of Representatives has just proposed a SALT write-off as high as $30,000, with some income limits.

Here’s what all this could mean for you and your tax bill.

SALT deduction: Key points

The SALT cap was originally introduced to offset tax cuts in the TCJA, signed into law during Trump's first term in 2017. However, the $10,000 cap has faced criticism for placing an undue burden on residents of states with higher taxes, which tend to lean Democratic.

However, the dynamics surrounding the SALT deduction cap are complex, particularly when it comes to how some Republican lawmakers see its impacts.

  • The SALT cap is often seen as penalizing residents in "blue states" with high state and local taxes. Data show California, Illinois, New Jersey, New York, and Pennsylvania account for most SALT deduction claims. (However, Texas, a "red state," is included in that data set.)
  • For example, before the SALT cap, the average SALT deduction in Connecticut was around $20,900 according to the National Association of Realtors. Just after the $10,000 limit was enacted, the average SALT deduction in CT dropped to about $9,700. So, some Connecticut taxpayers saw a nearly 58% deduction decrease.
  • However, some Republicans representing those states have become vocal about the need to raise or eliminate the cap. The urgency is heightened because the SALT deduction limit is set to expire at the end of 2025, if Congress doesn't act.

The cost of a SALT cap repeal (more on that below) and questions surrounding who benefits most (Tax Policy Center says high-income earners) are also key issues to be addressed in 2025.

GOP stance on SALT cap: Will "No SALT, No Deal" hold?

Rep. Mike Lawler (R-N.Y.) emerged as a key figure in this debate late last year. During an appearance on Bloomberg’s "Balance of Power," Lawler stated he wouldn’t support any tax proposal that doesn’t include the removal of the SALT cap.

He has emphasized that his backing and support from other representatives from New York, New Jersey, and California are essential for passing tax legislation. Lawler remarked, "I’ve been very clear. I will not endorse a tax proposal that does not remove the cap on SALT."

It’s also worth noting that Rep. Tom Suozzi (D-N.Y.), also known as "Mr. SALT," has been a prominent advocate for the restoration of the SALT Deduction for some time.

His mantra, "No SALT, no deal," became a rallying cry among some lawmakers from high-tax states.

Suozzi has consistently said he would oppose any tax legislation that doesn't address the SALT cap, arguing that it represents "double taxation" and is a significant financial burden for Long Island and Queens residents.

What's happening with the SALT Cap?

Former President Donald Trump has also weighed in. As Kiplinger reported, Trump called for lifting the SALT cap during his 2024 presidential campaign events, stating an intention to "get SALT back."

At the time, those comments brought mixed reactions. Some viewed it as a necessary pivot for constituents in high-tax states, while others criticized him for previously supporting the very legislation that imposed the cap.

Since then, lawmakers and Trump affirmed that some adjustment to the SALT cap is a priority in what he hopes will be one big reconciliation bill addressing tax, border security, and more.

Update: The House GOP’s draft legislation, released May 12, proposes raising the SALT deduction cap to $30,000 for married couples earning up to $400,000. For single filers, the cap would be $15,000, applying to those making up to $200,000.

  • For incomes above those limits, the deduction would gradually phase down by 20% for every dollar over the threshold.
  • But it wouldn’t drop below the current $10,000 cap for joint filers or $5,000 for singles.
  • Note: These details could still change as the bill moves through Congress.

Also worth noting: A few weeks ago, Bloomberg reported that Rep. Jeff Van Drew (R-N.J.) thought House Republicans could approve a $30,000 SALT cap., saying, “$30,000 is fine for me,” adding, "That’s where I think it ends up, by the way."

However, some in the caucus have already expressed concern that $30,000 isn't high enough.

In a press statement, Lawler and several other House lawmakers criticized the proposal, calling the $30,000 cap “woefully inadequate,” adding, "We reject this offer."

Cost of repealing or modifying the SALT cap

What about the cost? Eliminating the SALT cap could cost an estimated $1.2 trillion over ten years, according to the Committee for a Responsible Budget. That price tag raises concerns among some fiscal conservatives about federal revenue and deficit reduction.

So, this underscores another key issue in the upcoming debate over tax reform: fiscal responsibility. The Congressional Budget Office (CBO) has estimated that just making the TCJA permanent (a big item on Trump’s tax wish list) could cost more $4 trillion over ten years.

Potential changes to the SALT deduction

As negotiations and positioning begin in Congress regarding potential new tax legislation, it remains to be seen whether the House version of the SALT cap will be part of any final product.

Several options to deal with the SALT deduction have floated around this year with varied projected budget impacts.

Lawler and other SALT caucus members have reportedly pushed for caps as high as $62,000 for individuals or double that for couples. Some have referenced proposals to raise the cap to $100,000 for individuals and $200,000 for married couples.

The debate continues as the House works to get a version of its bill through the budget committee.

Remember: Any changes to the SALT deduction could impact taxpayers nationwide, particularly those in states with higher tax burdens, so keep an eye on tax changes involving this and other key deductions.
