Can I write off my car payment in 2026?
Short answer: no — but you may deduct the interest. The new deduction is real, and much narrower than the headlines: only the interest (never the principal), only a new, US-assembled vehicle, capped at $10,000, and it phases out by income. Check if your loan qualifies and what it's actually worth.

Methodology & data sources
The One Big Beautiful Bill Act created a temporary deduction (tax years 2025–2028) for interest on a qualifying vehicle loan, claimed above-the-line on the new Schedule 1-A — you don't have to itemize. It is capped at $10,000 of interest per year and phases out by $200 for every $1,000 of income (MAGI) above $100,000 (single) / $200,000 (married filing jointly), disappearing at $150,000 / $250,000. To qualify, the vehicle must be new (original use begins with you — no used cars), have its final assembly in the United States (determined by the VIN, not the brand — verify with the NHTSA decoder), be a car, minivan, van, SUV, pickup or motorcycle under 14,000 lbs GVWR, be for personal use (leases and business/fleet vehicles don't qualify), and the loan must be taken out after December 31, 2024 and secured by a first lien on the vehicle. Only the interest counts — never the principal — and the VIN must be reported on your return. We estimate your first-year interest by amortizing the loan amount, rate and term you enter; your actual deductible interest is what your lender reports and it falls each year. Unlike the tips, overtime and senior deductions, current IRS guidance does not list an SSN-for-employment requirement here; confirm on the final Schedule 1-A instructions. Our Freshness Keeper re-checks these rules against the IRS and Treasury.

Frequently asked questions
Can I write off my whole car payment?
No — only the interest portion, never the principal, up to $10,000 a year, and only on a qualifying new, US-assembled vehicle.
Does my "American" brand automatically qualify?
No. It's about where the vehicle's final assembly happened, not the badge. Some US brands are assembled abroad; some Toyota/Honda/BMW models are assembled here and qualify. Check the VIN.
Do used cars or leases qualify?
No. The vehicle must be new (original use begins with you), and leases don't qualify — only a purchase financed with a loan.
How much will I really save?
Usually a few hundred dollars. Typical first-year interest on a ~$40k loan is ~$2,000–$3,000, and the deduction shrinks as income rises past $100k/$200k.
