What This Means for Your Payment

If you itemize and your total deductions exceed $29,200, the government effectively subsidizes your mortgage interest. Your monthly tax refund (spread over the year) of $589 reduces the true after-tax cost of your mortgage.

Assumptions & Limitations

  • Uses 2024 federal income tax brackets and standard deduction amounts.
  • Mortgage interest is estimated as balance × rate (first-year, maximum estimate). Actual interest decreases each year as you pay down principal.
  • Assumes you have no other itemized deductions (charity, medical, etc.). If you do, your actual savings may be higher.
  • SALT deduction is capped at $10,000/year ($5,000 for Married Filing Separately) per current law.
  • Mortgage interest is fully deductible on balances up to $750,000 ($375,000 for MFS).
  • State income taxes are not modeled. Some states offer additional deductions.
  • Does not account for the Alternative Minimum Tax (AMT), which can reduce or eliminate this benefit.

The short answer

Is mortgage interest still tax deductible?

Yes, but far fewer people benefit than assume they do. Interest is deductible on up to $750,000 of mortgage debt and property tax falls under the $10,000 SALT cap — and you only gain if those combined itemized deductions exceed the standard deduction ($14,600 single / $29,200 married filing jointly for 2024). Below that you take the standard deduction and the mortgage saves you nothing at tax time.
