President Donald Trump’s “Big Beautiful Building” temporarily raised the limits of federal state and local tax deductions known as salt from $10,000 to $40,000 in 2025.
However, according to a Redfin report released last week, some residents of certain states could see greater tax benefits.
Chen Zhao, head of economic research at Redfin, said the results were “in line with what you might expect” and “there are substantial benefits to residents of certain states.”

Trump’s 2017 tax cuts limit the salt deduction to $10,000. Prior to 2018, salt deductions were unlimited, including state and local income taxes and property taxes. However, the so-called alternative minimum tax reduced the profits of some wealthy homeowners.
To benefit from salt, you should itemize your tax deductions rather than claiming a standard deduction. During the 2022 tax year, the latest IRS data showed that in 2022, only 10% of the deductions were likely to be deductibles and those taxpayers to be higher incomes.
It’s where taxpayers can see the biggest profits of the $40,000 salt deduction cap in 2025.
The biggest salt saving state
Trump’s law temporarily increased the salt deduction limit to $40,000 from 2025. Its benefits begin phase-out or decline of consumers making more than $500,000. Both figures will increase by 1% per year through 2029, with a higher deduction limit returning to $10,000 in 2030.
However, according to a Redfin report, certain state items could have greater benefits. Here are five states where residents can see their biggest savings from the new law.
New York: $7,092California: $3,995NEW JERSEY: $3,897Massachusetts: $3,835Connecticut: $3,133
Meanwhile, these five states are where Imager sees the smallest savings from Trump’s law.

To estimate savings, Redfin calculated how much a typical affected homeowner could deduct under the new salt law. They then applied a marginal tax rate of 24% to the amount more than the previous $10,000 salt cap.
However, this is “very simulated” and there are many assumptions, including property values, property tax estimates, and state income tax estimates, Zhao said. The report does not take into account local income taxes. This may vary widely from jurisdiction to jurisdiction.
Other measurements for salt deduction
Another report released in May by the Center for Bipartisan Policy analyzed the states that benefit most from salt deductions, based on the number of residents paying salt and where taxpayers have the largest salt deduction.
The average salt deduction for 2022 was nearly $10,000 in states such as Connecticut, New York, New Jersey, California and Massachusetts. The bottom five were Wyoming, Tennessee, Nevada, North Dakota and South Dakota.
These higher averages suggest the majority of taxpayers who claim that the deduction has approached the $10,000 cap, the researchers wrote.
Meanwhile, the states and districts with the highest proportion of salt claimants were Washington, DC, Maryland, California, Utah and Virginia. The bottom five were West Virginia, South Dakota, North Dakota, Ohio and Wyoming.
However, “Neither of these measures are perfect proxy for how states benefit from salt deductions, or they are affected by salt caps,” the researchers said.
