These guides explain the OBBBA car loan interest deduction (tax years 2025–2028) in plain English. It is a deduction, not a credit, worth up to $10,000 of loan interest a year (IRS: Section 70203 of H.R.1). You qualify on two tests: US final assembly and an income limit. Read them in order: shop, finance, verify, file, refinance.
The two tools give you a yes-or-no. The guides give you the why and the how. Start with a tool, then read the guide behind the answer.
Start with a tool
Does my car qualify?
Enter your VIN. The checker reads your assembly plant and country from NHTSA vPIC. It screens the US final-assembly test — free, no signup.
How much is it worth?
Enter your income and interest. The calculator applies the $100,000 single / $200,000 joint phase-out (IRS). It estimates your savings.
Guides by stage
Follow the deduction from the lot to the tax return. Each stage answers one question. The directory below links every guide.
Shop. Does a used car or a lease qualify? No. The shopping guide gives the exact IRS rule for lease-buyouts and dealer demos.
Finance. The pillar guide covers the rules for a new-loan purchase. It walks the $10,000 interest cap and the date test for loans after 12/31/2024. The income phase-out starts at $100,000 single, $200,000 joint.
Verify. Form 1098-VLI is the statement your lender sends. The verify guide reads it line by line. The checker confirms the car cleared US final assembly.
File. Schedule 1-A is where the deduction goes. The filing guides walk it onto Form 1040. That covers the VIN line down to the phase-out math.
Refinance. A refi keeps the deduction when the original loan started after 12/31/2024. The guide shows what survives and what breaks it.
Follow the deduction from the lot to the tax return, one stage at a time.
