If you financed a new vehicle in 2025 or later, you might be able to write off up to $10,000 a year in loan interest. But there’s a catch. That car has to have rolled off a U.S. assembly line. The new car loan interest deduction sounds simple on paper. In practice, the fine print knocks out a surprising number of popular models, including plenty with American badges on the hood.
This deduction comes from the One Big Beautiful Bill Act, signed into law on July 4, 2025. It lets eligible buyers deduct interest paid on a qualifying auto loan. That’s true whether they itemize or take the standard deduction. It’s a real change. Personal car loan interest hasn’t been deductible in nearly 40 years.
What exactly is the car loan interest deduction?
It’s a temporary federal tax break. It lets you deduct up to $10,000 of interest paid on a new vehicle loan each year, from 2025 through 2028. You claim it on Schedule 1-A of your Form 1040. You’ll need the vehicle’s VIN handy when you file.
The deduction only covers interest. It doesn’t touch your loan’s principal or your monthly payment as a whole. Lenders have to send you a statement showing how much interest you paid. It works a lot like the mortgage interest form homeowners get every January.
Which vehicles actually qualify for the car loan interest deduction?
A vehicle must meet several rules to qualify. It has to be new, bought for personal use, and financed with a loan rather than a lease. Its final assembly also has to happen in the United States. On top of that, it needs a gross vehicle weight rating under 14,000 pounds. That covers nearly every car, SUV, minivan, pickup, and motorcycle sold today.
That “final assembly in the U.S.” rule is where things get messy. Plenty of vehicles from Honda, Hyundai, Nissan, and Toyota are built overseas or in Mexico and Canada. Some industry voices have pointed out this requirement could shut out many popular imports entirely. That includes models with a familiar American nameplate.
Here’s a rough breakdown of what tends to qualify versus what doesn’t. It’s based on where 2026 model-year production actually happens:
| Likely Qualifies (U.S.-assembled) | Likely Does Not Qualify (imported) |
|---|---|
| Tesla Model 3 / Model Y (Fremont, CA or Austin, TX) | Many compact sedans built in Japan or South Korea |
| Toyota Camry, Tundra, Corolla Cross Hybrid (Kentucky plants) | Vehicles assembled in Mexico or Canada, including some Ram, Chevy, and Buick models |
| Honda Accord, Passport, Odyssey, Ridgeline (Ohio/Indiana/Alabama) | Used vehicles of any brand or origin |
| Jeep Grand Cherokee, Jeep Gladiator | ATVs, trailers, and campers |
| Ford Explorer, Lincoln Aviator, Lincoln Navigator | Vehicles bought for business or commercial use |
Notice that Tesla’s entire U.S. lineup makes the cut. The company builds domestically, so there’s no ambiguity.

How do you check if your specific car qualifies?
Don’t trust the badge or the brand name. Trust the VIN instead. The IRS and NHTSA both recommend running your Vehicle Identification Number through the NHTSA VIN Decoder. Do this before you sign any loan paperwork.
A VIN starting with 1, 4, or 5 generally signals U.S. assembly. A 2 points to Canada, a 3 to Mexico, J to Japan, and K to South Korea. Dealerships often don’t flag this for you. It pays to check it yourself. The same model can be built in different countries depending on trim or model year.
Who actually gets to claim the full $10,000?
Not everyone qualifies for the maximum amount. The deduction phases out once your modified adjusted gross income tops $100,000 for single filers, or $200,000 for joint filers. It shrinks by $200 for every $1,000 you earn above that line. It disappears entirely around $150,000 for single filers, or $250,000 for joint filers.
So a single filer earning $105,000 loses $1,000 off the top. That caps their deduction at $9,000 instead of $10,000. Middle-income buyers get the full benefit. Higher earners see it shrink fast.
Should the deduction change what you buy?
I wouldn’t let a tax deduction alone talk you into a car you don’t actually want. But say you’re already cross-shopping two similar vehicles. One is built in Kentucky, the other ships in from overseas. This deduction tips the scale toward the domestic one. That’s especially true paired with rising tariff-driven price increases on imported models.
It also matters more than ever given how car payments have climbed to record highs in 2026. Shaving a few hundred dollars off your tax bill won’t fix an underwater loan. But it’s a real, if modest, offset against rising financing costs.
You can read the official rules straight from the IRS guidance on the car loan interest deduction. It’s worth a look before you file.
FAQ
Does leasing a car qualify for this deduction?
No. The deduction only applies to loans secured by a lien on the vehicle. Lease payments don’t count, even on an otherwise eligible, U.S.-built model.
Can I claim the deduction for a used car?
No. Only new vehicles qualify. The original use of the vehicle must start with you as the buyer. A used Tesla or used Camry won’t qualify, no matter how American-built it is.
Do I need to itemize my taxes to claim this?
No. This is available whether you take the standard deduction or itemize. That makes it accessible to far more taxpayers than traditional itemized deductions like mortgage interest.
How long will this deduction be available?
It applies to qualifying loans originated between January 1, 2025, and December 31, 2028. That’s unless Congress acts to extend or change it before then.
