GMC Sierra HD car loan interest deduction

Up to $10,000/yr

Does the Sierra HD Qualify for Car Loan Interest Deduction?

Short answer: Only some do: Flint, Michigan, and plants outside the U.S. both build the Sierra HD, so check the window sticker or a VIN starting with 1, 4, or 5 for U.S. assembly.

The loan must be for a new vehicle for personal use, taken out after 2024, and secured by the car. The deduction phases out above $100,000 of income ($200,000 joint); leases and used cars don't qualify.

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.
