A Democratic bill to roll back but not fully repeal the GOP tax law's cap on the state and local tax (SALT) deduction would lower federal revenue by $223 billion over 10 years, according to an analysis released Monday by the right-leaning Tax Foundation.

The GOP tax law imposes a cap of $10,000 for both single and married filers.

Republicans included the SALT deduction cap in their 2017 law in order to raise revenue to help pay for tax cuts in the measure. But lawmakers on both sides of the aisle from high-tax states have expressed concerns that the provision will disproportionately hurt their constituents.

The Tax Foundation estimated that Underwood and Casten's bill would cost more than $200 billion from 2020 to 2029, and that all of that revenue impact would take place from 2020 to 2025. That's because the cap, along with most other individual tax provisions in the 2017 law, expires after 2025, the group said.

The think tank estimated that Underwood and Casten's bill has a smaller price tag than other bills lawmakers from high-tax states have introduced in recent months to completely eliminate the SALT deduction cap.

Kyle Pomerleau, who wrote the Tax Foundation's report, said on Twitter that Underwood and Casten's proposal is "much more workable" than other proposals on the SALT deduction.

Underwood and Casten said when they introduced their bill that they assume some sort of pay-for would be attached to their bill if it moved through Congress. They also said that they proposed legislation to raise the SALT deduction cap rather than fully repeal it so that they could focus tax relief on the middle class.

However, the Tax Foundation estimated that those in the top 10 percent of income would benefit the most from the bill. The group estimated that those in the bottom three-fifths of income wouldn't be affected by the bill, because those taxpayers typically are utilizing the 2017 tax law's larger standard deduction rather than itemizing their deductions.

Casten and Underwood said Monday in a statement: “The Republican tax law failed to put middle class families first. Our legislation would help Illinois families disproportionately burdened by the changes to the State and Local Tax deduction to ensure middle class families aren’t excessively burdened with an unfair double-tax.”

Democrats have frequently criticized the Tax Foundation, which is generally supportive of the GOP tax law.

Trump said in a tweet Monday that New Yorkers "didn’t even put up a fight against SALT - could have won." Democratic lawmakers responded to the tweet by saying they did fight against the SALT deduction cap and that if Trump wants to restore the full deduction, he should work with them.
