Boat loan interest

Varies

Can You Write Off Boat Loan Interest?

Short answer: Yes when the boat has a sleeping berth, galley, and head: it can count as a second home for the mortgage interest deduction.

The loan must be secured by the boat.

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.
