President Donald Trump's "big beautiful bill" increases the SALT deduction limit to $40,000 for 2025
However, there's a phaseout, or benefit reduction, between $500,000 and $600,000 of income
Those individuals could face a "SALT torpedo," or artificially high tax rate, said certified public accountant Jeff Levine

But the phaseout, or income-based benefit reduction, could trigger a tax surprise for some higher earners, experts say
If you itemize tax breaks, you can claim the SALT deduction, which includes state and local income taxes and perty taxes
Trump's legislation raises the SALT deduction limit to $40,000 starting in 2025, with a 1% yearly increase through 2029, before reverting to $10,000 in 2030
However, the $40,000 SALT cap starts to phase out once modified adjusted gross income, or MAGI, exceeds $500,000
The SALT limit drops to $10,000 once MAGI reaches $600,000
MAGI is adjusted gross income with some tax breaks added back in
This phaseout can create a "SALT torpedo" — an artificially high tax rate — when MAGI falls between $500,000 and $600,000, certified public accountant Jeff Levine said in a LinkedIn post this week
In some cases, you could pay a 45. 5% federal tax rate on earnings between those thresholds, experts say

How the SALT deduction phaseout worksUnder Trump's legislation, the SALT deduction limit for 2025 is now $30,000 higher
But a 30% phaseout kicks in once MAGI exceeds $500,000 for 2025
Between $500,000 and $600,000, "you're losing 30% for every dollar" of benefit between those thresholds, said certified financial planner Jim Guarino, managing director at Baker Newman Noyes in Woburn, Massachusetts
At $600,000, if you multiply the extra $100,000 of income by 30%, that's a $30,000 benefit reduction, which drops the $40,000 SALT cap back to $10,000
A 'quirky' phaseout boosts tax rateWith the 30% SALT deduction phaseout between $500,000 and $600,000 MAGI, some individuals could pay higher-than-expected tax on earnings between those thresholds, according to Robert Keebler, a CPA with tax advisory firm Keebler & Associates in Green Bay, Wisconsin
Between $500,000 to $600,000, you're increasing taxable income while losing part of the SALT deduction, which raises your effective tax rate — the percent of taxable income you pay
If taxable income rises while the SALT deduction falls, your effective tax rate on income between $500,000 to $600,000 could far exceed your regular income tax rate, Keebler said in a LinkedIn post last week. "It's definitely a quirky little phaseout vision," Andy Whitehair, a CPA and a director with Baker Tilly's Washington tax council practice, told CNBC. "When people start actually crunching numbers, they might be in for some surprises. "Whitehair also d a basic example of the phaseout on LinkedIn this week
If your income is $500,000 and you subtract $75,000 of itemized deductions (including $40,000 for SALT), your taxable income is $425,000
By contrast, $600,000 of income would drop the SALT deduction to $10,000, which reduces itemized deductions to $45,000, and raises taxable income to $555,000
In this simplified example, there is $45,500 more federal tax owed by earning $100,000 more, which is 45. 5%, Whitehair said
If your 2025 earnings could be near $500,000, you should run jections with a tax advisor and weigh strategies to reduce MAGI, experts say
With the steep tax penalty between $500,000 and $600,000, you may reconsider Roth individual retirement conversions, incurring large capital gains or other moves that could boost your income, according to Keebler
