1Check your vehicle
Your 17-character VIN is on your registration, insurance card, loan paperwork, or the driver-side dashboard.
2Check your loan
The vehicle is only half of it. All five of these need to be "Yes."
3Estimate your deduction
Use the interest from your lender's year-end statement (Form 1098-VLI).
Common questions
What exactly does the vehicle need?
It must be new (original use starts with you), bought for personal use, a car, minivan, van, SUV, pickup or motorcycle made primarily for public roads, with a gross vehicle weight rating under 14,000 lbs, and with final assembly in the United States. Brand doesn't matter: plenty of foreign-brand vehicles are assembled here, and some American-brand vehicles are not.
How does the IRS want me to verify U.S. assembly?
IRS Publication 6126 lists three ways: the information label on the vehicle at the dealer, the VIN, or NHTSA's VIN Decoder. This tool reads the plant location from NHTSA's database. If it comes back blank, check the window sticker or your purchase paperwork.
How much can I deduct?
Up to $10,000 of interest per year for 2025 through 2028. The cap is reduced by $200 for every $1,000, or part of $1,000, that your modified AGI is over $100,000 ($200,000 if married filing jointly). It reaches zero at $150,000 single or $250,000 joint.
Is the deduction the same as money back?
No. A deduction lowers your taxable income; your actual savings is roughly the deduction times your tax bracket. $3,000 of deductible interest in the 22% bracket saves about $660.
Do I need to itemize?
No. It goes on Schedule 1-A and works with the standard deduction. You'll need to report the VIN on your return.
Does a used car, lease, or loan from a family member count?
Used vehicles and leases don't qualify. The loan must be taken out after December 31, 2024 to buy the vehicle and be secured by a first lien on it. Loans from related parties generally don't qualify.
What about refinancing?
A refinance of a qualifying loan generally still qualifies if it's secured by a first lien on the vehicle and the new starting balance doesn't exceed the old loan's ending balance. Interest on any cash-out above that doesn't count.
I use the vehicle partly for business. Can I double up?
No. Interest you deduct as a business expense can't also be claimed under this deduction. Self-employed people sometimes come out ahead claiming the business share as a business expense; that's a question for your tax preparer.
