For nearly forty years, personal car loan interest was not deductible. The 2025 tax law changed that — up to $10,000 per year, and you don't have to itemize. But the requirements are strict enough that many Maryland car buyers won't qualify, and the single most important one has to be checked before you sign at the dealership, not after.
The One Big Beautiful Bill Act created a temporary federal deduction for interest paid on qualifying vehicle loans — up to $10,000 per year, for tax years 2025 through 2028. Like the tips and overtime deductions, it's available whether you itemize or take the standard deduction, and it's claimed on the new Schedule 1-A of Form 1040.
This is a genuine break for Frederick County families financing a new vehicle. But "no tax on car loan interest" is a headline, not a description — the actual rules are narrow. For the full picture of the 2025 law, see our complete OBBBA guide.
Key details: up to $10,000 of qualified interest per year, tax years 2025–2028. Available with or without itemizing. Loan must originate after December 31, 2024. Vehicle must be NEW, for personal use, and assembled in the United States. Phases out above $100,000 modified AGI (single) / $200,000 (joint). The VIN must be reported on your return every year you claim it.
Miss any one of these and the deduction is gone entirely — there's no partial credit for coming close:
| Requirement | Qualifies | Does NOT Qualify |
|---|---|---|
| Vehicle condition | New — original use begins with you | Used, certified pre-owned, or "new to you" |
| Final assembly | United States | Assembled anywhere else — regardless of brand |
| Loan date | Originated after December 31, 2024 | Existing loans from 2024 or earlier |
| How you acquired it | Financed purchase, secured by a first lien on the vehicle | Leases, cash purchases, home equity loans, personal/unsecured loans |
| Use | Personal | Business, commercial, or fleet vehicles |
| Vehicle type | Car, minivan, van, SUV, pickup, or motorcycle under 14,000 lbs GVWR | Heavy commercial vehicles |
Assembly location has nothing to do with the badge on the hood. A Honda built in Ohio qualifies. A Ford assembled in Mexico does not. Buyers routinely assume "American brand" means "American made" — and it doesn't. Check the actual vehicle before you sign: the Final Assembly Point is printed on the window sticker, and the VIN encodes it too (you can confirm with NHTSA's free VIN decoder). Assembly location can vary by trim and model year for the same nameplate, so verify the specific car on the lot, not the model in general.
This is the single most actionable thing in this article. If the deduction matters to your budget, make U.S. final assembly part of your shopping criteria from the start — not a question you ask your CPA in April, when it's too late to do anything about the answer.
The deduction shrinks by $200 for every $1,000 of modified AGI above the threshold:
That's a steep ramp. A single Frederick County professional earning $125,000 has already lost half the benefit; at $150,000, it's gone entirely.
Here's the reality check most coverage skips: the $10,000 cap is far larger than what a typical buyer's interest actually is. On a roughly $48,000 new vehicle financed over 60 months at prevailing rates, first-year interest runs in the neighborhood of $3,000 — well under the cap. The deduction is limited by your actual interest paid, not by the headline number.
At a 22% federal bracket, $3,000 of deductible interest is about $660 in federal tax savings in year one — and it shrinks each year as your loan amortizes and the interest portion of each payment falls. Real, worth claiming, and not the four-figure windfall the "$10,000" framing implies. Analyses of the provision put typical savings in the several-hundred-dollar range for most qualifying buyers.
The paperwork differs depending on the year:
Either way, the VIN goes on your tax return every year you claim the deduction. Keep your purchase documents, window sticker, and lender statements together — this is a deduction with a documentation trail, and it's one the IRS can verify against the vehicle itself.
As with the other new OBBBA deductions, this one is federal only — Maryland has not conformed, so your car loan interest remains fully non-deductible on your Maryland return. Don't adjust Maryland withholding on the strength of a federal deduction; that's how a pleasant April surprise turns into an unpleasant one. Our guide to Maryland vs. federal tax differences covers the pattern in full.

Book a ConsultationIt depends entirely on where that specific vehicle was assembled, not on the brand. Many Toyotas, Hondas, and other foreign-brand vehicles are assembled in the U.S. and qualify; some American-brand vehicles are assembled abroad and don't. Check the Final Assembly Point on the window sticker or run the VIN through NHTSA's decoder — and do it for the exact car, since it can vary by trim and model year.
No. Leases are excluded from this deduction entirely — the law requires a loan secured by a first lien on a vehicle you own. If the deduction matters to you, that's a factor to weigh in the lease-versus-buy decision on your next vehicle.
Unfortunately not — the vehicle must be new, meaning its original use begins with you. Certified pre-owned, demo units with meaningful prior use, and any "new to you" vehicle are all excluded, no matter how good the deal was.
Yes, though reduced. At $110,000 as a single filer you're $10,000 into the phaseout, which cuts the allowable deduction by $2,000 — you still deduct the rest of your qualified interest, which for a typical loan is likely under the reduced ceiling anyway. It's worth running the actual numbers rather than assuming you're out.
