Only new vehicles assembled in the United States qualify for the $10,000 auto loan interest deduction. That single rule knocks out roughly half the cars on dealer lots today. If you’re financing a new car and hoping to write off the interest, where that car was bolted together matters more than the badge on the hood.
This tax break sounds generous on paper. But the eligibility rules are narrower than most car shoppers realize. Here’s exactly which vehicles make the cut and which ones don’t.
What is the auto loan interest deduction, exactly?
It’s a new federal tax deduction, created by the One Big Beautiful Bill Act. It lets eligible buyers deduct up to $10,000 a year in interest paid on a new vehicle loan. It applies to tax years 2025 through 2028. You can claim it whether you itemize or take the standard deduction.
The law is codified as a temporary addition to the tax code. Taxpayers claim it on a new form called Schedule 1-A. According to CNBC’s reporting on the rule, the loan must have originated after December 31, 2024. It also must be secured by the vehicle itself. Lease payments don’t count. Leasing isn’t borrowing against ownership — it’s rent.
Which cars actually qualify for the auto loan interest deduction?
A vehicle qualifies only if it’s new, for personal use, and weighs under 14,000 pounds. It must also have final assembly in the United States. That last requirement eliminates many popular models, even ones built by American brands, if they happen to roll off a line in Mexico or Canada.
Final assembly location is the whole ballgame here. It’s not where the company is headquartered. It’s not even what badge is on the trunk. A Honda built in Ohio qualifies. A Chevy built in Mexico doesn’t.
Here’s a snapshot of popular models and where they currently stand, based on recent assembly-plant data:
| Model | Final Assembly Location | Qualifies? |
|---|---|---|
| Toyota Camry | Georgetown, Kentucky | Yes |
| Honda Accord | Marysville, Ohio | Yes |
| Honda CR-V | Greensburg, Indiana / East Liberty, Ohio | Yes |
| Tesla Model 3 / Model Y | Fremont, CA / Austin, TX | Yes |
| Jeep Gladiator / Grand Cherokee | Toledo, Ohio | Yes |
| Toyota Tacoma | Tijuana, Mexico | No |
| Chevrolet Equinox | Ramos Arizpe, Mexico | No |
| Ford Maverick | Hermosillo, Mexico | No |
| Honda HR-V | Celaya, Mexico | No |
| Toyota RAV4 (gas) | Woodstock, Ontario, Canada | No |
Notice the pattern. Some of the best-selling models in America — the Tacoma, the Maverick, the HR-V — don’t make the list. Meanwhile, plenty of foreign-badged vehicles do qualify, because they’re built in American plants. As one analysis found, of the 25 most popular new car models sold domestically in 2024, 14 underwent final assembly in the United States.
How do you check if your specific car qualifies?
You check the VIN, not the brand name or trim level. Assembly plants can vary by model year. They can even vary by individual production run. The safest method is the NHTSA’s free VIN Decoder tool. It shows the exact plant where your car was built.
You can also look at the window sticker still on new cars at the dealership. It lists the final assembly point in plain text. Don’t assume — verify before you sign the loan paperwork. The IRS requires you to report the VIN on your return every year you claim the deduction.
Who actually benefits from the auto loan interest deduction?
The deduction phases out starting at $100,000 of modified adjusted gross income for single filers. For joint filers, it starts at $200,000. It disappears entirely at $150,000 and $250,000 respectively. That leaves a fairly narrow band of middle-income buyers as the real beneficiaries.
Even for buyers who qualify, the dollar savings are modest. A $50,000 loan at a typical rate generates a few thousand dollars in interest during the first year. Since this is a deduction, not a credit, it only reduces taxable income. It doesn’t cut your tax bill dollar for dollar. Most qualifying buyers should expect tax savings in the hundreds of dollars annually, not thousands.
Is this deduction a reason to buy a new car right now?
No. A few hundred dollars in annual tax savings shouldn’t be the deciding factor in a five-figure purchase. It’s a nice bonus if you were already planning to finance a qualifying new vehicle. But it shouldn’t push you toward a car you wouldn’t otherwise choose.
If you’re cross-shopping a US-built model against an import with similar pricing and features, this deduction can be the tiebreaker.

And if you’re shopping EVs specifically, our decision framework for buying an EV in 2026 walks through how incentives like this one factor into the real math.
Worth noting too: used cars, certified pre-owned vehicles, and leases are completely excluded from this deduction. It doesn’t matter where they were assembled. If you’re weighing a CPO purchase against new, that’s one more data point tilting toward financing new — assuming the car you want is actually built domestically.
FAQ
Does the auto loan interest deduction apply to used cars?
No. The deduction only applies to new vehicles where you are the first registered owner. Used cars, certified pre-owned vehicles, and cars purchased at lease-end don’t qualify under any circumstances.
Can I claim this deduction if I lease my car?
No. Lease payments are treated as rent, not loan interest. Lessees can’t claim this deduction even if the vehicle itself is US-assembled.
Do electric vehicles qualify for the auto loan interest deduction?
Yes, as long as they meet the same rules as gas vehicles: new, for personal use, under 14,000 pounds, and assembled in the US. The deduction doesn’t care about powertrain. EVs, hybrids, and gas vehicles are all treated identically.
How do I find my car’s final assembly location?
Enter your 17-character VIN into the National Highway Traffic Safety Administration’s VIN Decoder tool. It will show the exact plant and country where the vehicle was built. You can also check the window sticker on a new vehicle at the dealership.
