To a first approximation, no one actually takes advantage of the mortgage tax deduction any more because the standard deduction is so high and the cap on state tax/property taxes is so low that most people don’t itemize.

Only about 10% itemize.

And the majority of those make more than $500K. The deductions are probably mostly some combination of mortgages on very expensive properties or very large charitable contributions, probably often tax-shielded in some manner.

  • You can’t deduct interest on personal income tax for mortgages over $750,000, so it seems somewhat unlikely that such deductions make up any significant amount of the deductions: https://www.irs.gov/publications/p936#en_US_2023_publink1000...

    • The $750,000 amounts to a cap on the deduction. If your mortgage is in excess of that amount, you would pro-rate the deductible interest accordingly.

      I think it's reasonable to say that the folks with the largest mortgages are the ones most likely to itemize mortgage interest, even if they are capped.
