Auto Loan Interest Deduction 2026: The $10,000 "No Tax on Car Loan Interest" Explained
Quick Answer
For 2025 through 2028, you can deduct up to $10,000 per year in interest on a loan for a new, US-assembled, personal-use vehicle — whether or not you itemize. The deduction phases out between $100,000-$150,000 MAGI ($200,000-$250,000 joint). Used cars, leases, and business vehicles don't qualify.
How the $10,000 Deduction Works
Personal auto loan interest hasn't been deductible since 1986. The OBBBA carved out a narrow, temporary exception (OBBBA §70203; IRS final regulations T.D. 10054): for tax years 2025 through 2028, interest on a qualifying passenger vehicle loan is deductible up to $10,000 per year.
It's an above-the-line deduction — claim it on top of the 2026 standard deduction ($16,100 single / $32,200 married) without itemizing. Over the four years, that's up to $40,000 in total deductions.
Does Your Vehicle Qualify? (6 Requirements)
- New: you must be the original owner — used vehicles are excluded.
- US final assembly: check the VIN at nhtsa.gov/vin-decoder; you report the VIN on your return.
- Personal use: business or commercial vehicles use separate depreciation rules instead.
- Under 14,000 lbs gross vehicle weight; at least 2 wheels; manufactured for street use.
- Loan originated after December 31, 2024, secured by a lien on the vehicle, not from a related party.
- No lease: leased vehicles are explicitly excluded.
Also excluded: campers, RVs, fleet sales, salvage-title vehicles, and — importantly — negative equity rolled over from a trade-in. If you owed more than your old car was worth, interest on that rolled-in balance doesn't qualify.
Income Limits: The $100,000 / $200,000 Phaseout
This phaseout starts lower than other OBBBA provisions — middle-income households benefit most. The deduction shrinks by $200 for every $1,000 of MAGI above $100,000 single / $200,000 joint.
| Single Filer MAGI | Max Deduction |
|---|---|
| Under $100,000 | $10,000 (full) |
| $120,000 | $6,000 |
| $140,000 | $2,000 |
| $150,000+ | $0 |
Worked Example: $468 in Real Tax Savings
James buys a new US-assembled SUV for $38,000 in 2026: $5,000 down, $33,000 financed at 7% for 60 months. First-year interest: about $2,129.
| Item | Amount |
|---|---|
| Year-1 interest paid | $2,129 |
| Deduction (under $10K cap) | $2,129 |
| James's marginal bracket (22%) | × 22% |
| Federal tax savings | $468 |
At higher rates the savings grow fast: the same loan at 9% generates ~$2748 in first-year interest → $605 saved at the 22% bracket. A buyer maxing the $10,000 cap at the 24% bracket saves $2,400/year.
What Counts as Deductible Interest?
Per T.D. 10054, qualifying interest isn't just the stated rate — it can include points, origination charges, capitalized interest, prepayment penalties, and late-payment charges, as long as they're treated as interest for federal tax purposes and reported by the lender. Your lender must issue an annual statement (Form 1098-VLI) showing total interest paid.
How to Claim It
- Confirm US assembly via the NHTSA VIN decoder before you buy.
- Keep the loan originated after 12/31/2024 and secured by the vehicle.
- Report the VIN on your federal return and use the lender's Form 1098-VLI interest statement.
- Refinanced loans: interest qualifies only up to the original loan's amount and term.
Frequently Asked Questions (FAQ)
Does my used car qualify?
No. Only new vehicles where you are the original owner qualify. Used cars and leases are explicitly excluded.
Do I need to itemize?
No. It's an above-the-line deduction — claim it with the $16,100 single / $32,200 married standard deduction.
What if I trade in a car I'm upside-down on?
Interest on the negative-equity portion rolled into the new loan does NOT qualify — only debt used to buy the new vehicle counts.
How do I prove US assembly?
Use the NHTSA VIN decoder (nhtsa.gov/vin-decoder) to confirm the manufacturing plant, and report the VIN on your return.

Tax years 2025 through 2028. It expires December 31, 2028 without new legislation.
