Does Your Car Qualify for the $10,000 Interest Deduction?

The New Car Loan Interest Deduction: Credit vs. Deduction

The OBBBA replaced the old $7,500 EV tax credit (which expired September 30, 2025) with a broader $10,000 annual interest deduction for qualifying auto loans. The key difference: the old benefit was a credit (dollar-for-dollar tax reduction) limited to EVs. The new benefit is a deduction (reduces taxable income) available for any new US-assembled vehicle — gas, hybrid, or electric.

This means the actual tax savings depend on your marginal tax bracket. A $5,000 deduction saves $1,100 for someone in the 22% bracket, but only $600 for someone in the 12% bracket. The old $7,500 credit was worth exactly $7,500 regardless of bracket.

The VIN Test: How to Know If Your Car Qualifies

The vehicle must have final assembly in the United States. The fastest way to check: look at the first character of your VIN (Vehicle Identification Number). VINs starting with 1, 4, or 5 indicate US assembly. VIN starting with 2 = Canada, 3 = Mexico, J = Japan, W = Germany, K = South Korea — none of these qualify.

Important: the brand does not determine eligibility. A Toyota Camry assembled in Georgetown, Kentucky (VIN starts with 4) qualifies. A Ford Maverick assembled in Hermosillo, Mexico (VIN starts with 3) does not. Always check the VIN, not the brand name.

You can verify assembly location through the NHTSA VIN Decoder (nhtsa.gov) or by checking the "Final Assembly Point" on the vehicle's window sticker (Monroney sticker) at the dealership.

Income Phase-Out Rules

The deduction phases out for higher earners. For single filers, it begins reducing at $100,000 MAGI and is fully eliminated at $150,000. For married filing jointly, phase-out begins at $200,000 and ends at $250,000. The reduction is $200 for every $1,000 over the threshold. A single filer earning $125,000 loses 50% of the deduction.

How Much Interest Do Car Buyers Actually Pay?

The average new car price in 2026 is approximately $48,000. At a 6.5% interest rate on a 60-month loan, you pay roughly $3,100 in interest in year one, declining each year. Most buyers will not reach the $10,000 cap unless they purchased a luxury vehicle with a higher interest rate. The deduction is most valuable for buyers financing $40,000+ at rates above 7%.

How to Claim the Deduction

Report the deduction on Schedule 1-A, Part IV of your federal tax return. You will need your VIN (17 characters) and the total interest paid during the tax year (provided by your lender on Form 1098-VLI or a year-end statement). The deduction is above-the-line — you can claim it whether you take the standard deduction or itemize. It applies to tax years 2025 through 2028.

⚡ CalcWolf Insight

According to the Bipartisan Policy Center, of the 25 most popular new cars sold in the US, only about 57% had final assembly in the United States. A Toyota Camry (Kentucky) qualifies, but a Ford Maverick (Mexico) does not. Always check the VIN — the brand name is irrelevant for this deduction.

Frequently asked questions
Does my car qualify if the VIN starts with 1?
Yes. VINs starting with 1, 4, or 5 indicate final assembly in the United States. Your vehicle is likely eligible if it also meets the other requirements: new (not used), personal use, passenger vehicle under 14,000 lbs, and your income is below the phase-out threshold.
Can I deduct interest on a used car loan?
No. The OBBBA deduction applies only to new vehicles where you are the original purchaser. Used vehicles, certified pre-owned, and lease agreements do not qualify. The vehicle must be for "original use" by the taxpayer.
What happened to the $7,500 EV tax credit?
The Inflation Reduction Act EV credit expired on September 30, 2025. It was replaced by the OBBBA auto loan interest deduction, which is broader (covers all fuel types) but works differently (deduction vs. credit). If you purchased a qualifying EV before October 2025, you can still claim the old credit on your 2025 return.
Is a Tesla Model 3 eligible for the deduction?
If your Tesla Model 3 was assembled at the Tesla factory in Fremont, California (VIN starts with 5), yes. Tesla also assembles Model Y at Gigafactory Texas (VIN starts with 7 in some cases). Always verify your specific VIN through the NHTSA decoder.
Can I claim this deduction AND use the car for business?
The vehicle must be used primarily (over 50%) for personal purposes. If you claim Section 179 depreciation or business-use deductions on the same vehicle, you cannot also claim the OBBBA personal interest deduction. Choose the more beneficial option with your tax advisor.
