Can I Write Off Mortgage Interest?

Short answer: Yes, if you itemize: interest on up to $750,000 of mortgage debt on your main and second home is deductible.

Loans from before December 16, 2017 keep the old $1 million limit.

Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
