SALT Cap 2025 Boost Could Cut Taxes for Florida Filers
Florida homeowners may qualify for thousands in federal tax savings starting with 2025 returns, thanks to a sharp increase in the SALT (State and Local Tax) deduction cap. The One Big Beautiful Bill Act raises the limit from $10,000 to $40,000, offering a new chance to benefit from itemized deductions—even in a state with no income tax.
The updated SALT deduction cap allows up to $40,000 in state and local tax deductions for both joint and single filers. For married taxpayers filing separately, the limit is $20,000. These caps apply to paid property taxes, sales taxes, and state income taxes—though Florida filers primarily benefit from deducting property taxes due to the absence of a state income tax.
To take advantage of the new deduction cap, taxpayers must itemize on Schedule A of Form 1040. This benefit only applies to individuals whose deductible expenses exceed the standard deduction, which increases in 2026 to $32,200 for joint filers and $16,100 for single filers. If total deductions fall below those thresholds, the standard deduction will offer more value.
The higher SALT cap takes effect with the 2025 tax year, which is reported on tax returns filed in 2026. It will rise slightly each year through 2029, based on an inflation adjustment formula. Without further legislative action, the cap will return to $10,000 in 2030, as initially outlined in the Tax Cuts and Jobs Act.
Consider a married couple in Broward County who pay $21,000 in annual property taxes. In addition, they contribute $7,000 to charity and pay $10,500 in mortgage interest. Under the previous SALT limit, only $10,000 of those property taxes could be deducted, totaling $27,500 in itemized deductions. With the expanded cap, the full $21,000 becomes deductible, pushing their itemized deductions to $38,500.
This $11,000 increase could reduce their federal income tax bill by over $2,600, assuming a 24% tax bracket. These savings are only available to those who itemize, and homeowners near the threshold may now find it worthwhile to run the numbers.
The expanded cap phases out for higher earners. For taxpayers with modified adjusted gross income over $500,000, the deduction is reduced at a rate of 30% of the excess income. By design, this means the highest earners may only receive a partial benefit or none at all.
“Many Florida homeowners who previously defaulted to the standard deduction should reassess in 2025,” said an IRS spokesperson. “These changes create tax planning opportunities that didn’t exist under the old cap.”
Florida taxpayers should start preparing now. First, review property tax assessments and year-end mortgage interest totals to estimate 2025 deductions. Second, compare those figures against the new standard deduction to determine whether itemizing is a sensible option.
Those planning home improvements should also consider how changes to property value might affect future tax bills and deductions. For filers close to the phaseout threshold, it’s essential to work with a tax professional who can help project income levels and estimated payments.
Because Florida has no income tax, residents may also elect to deduct sales tax. However, for most homeowners, property tax deductions under the new SALT cap will offer far more significant savings.
