Car Loan Interest Deduction 2026
Deduct up to $10,000 of interest paid on a loan for a new, U.S.-assembled personal vehicle — even if you don't itemize.
Quick answer
Interest on a loan for a new personal-use vehicle with final assembly in the United States is deductible up to $10,000 for tax years 2025 through 2028. The deduction falls by $200 for every $1,000, or part of $1,000, of modified AGI above $100,000, or $200,000 on a joint return, reaching zero just past $149,000 and $249,000. Used vehicles and leases do not qualify, and payroll tax is unaffected.

What the phase-out actually does
A single filer claiming the full $10,000 of qualified interest. Note that the reduction rounds UP: one dollar over the threshold costs a whole $200 step. Every row is produced by the same calculation the estimator above uses, at a 22% marginal rate.
| Modified AGI | Interest paid | Before phase-out | Phase-out | Deduction | Tax saved |

| $99,999$1 below the phase-out start — still the full amount | $10,000 | $10,000 | — | $10,000 | $2,200 |

The two shaded rows at the top are the ones worth noticing: the deduction is still whole at the threshold, so reaching it costs nothing. The rows at the bottom show where it finally runs out.
What the car loan interest means in plain English
The One Big Beautiful Bill Act revives a deduction for personal car loan interest — something that hadn't been allowed since the 1980s. For tax years 2025 through 2028, you can deduct up to $10,000 of interest paid on a qualifying auto loan, claimed on Schedule 1-A whether you itemize or claim the standard deduction.
To qualify, the loan must be for a new (not used) personal-use vehicle whose final assembly took place in the United States, and the loan generally must have originated after December 31, 2024. The vehicle must be secured by the loan (a first-lien purchase loan), and lease financing does not qualify.
The deduction reduces income tax only and phases out at higher incomes — beginning at $100,000 MAGI for single filers and $200,000 for married couples filing jointly, reduced by $200 for every $1,000 above the threshold. You can verify U.S. final assembly using the NHTSA VIN decoder.
Guides & tools for the car loan interest
Who qualifies
- The loan financed a new (not used) vehicle for personal use, originated after December 31, 2024.
- The vehicle underwent final assembly in the United States (confirm with the NHTSA VIN decoder).
- The loan is secured by the vehicle as a first lien — leases and unsecured loans do not qualify.
- Your MAGI is below the phase-out ceiling for your filing status.
Common mistakes to avoid
- Claiming interest on a used vehicle or a lease — only new, financed purchases qualify.
- Assuming any car qualifies — the vehicle must have final assembly in the U.S.
- Deducting interest on a loan that originated on or before December 31, 2024.
- Including interest on a business-use vehicle, which is handled under separate business rules.

Which vehicles qualify for the car loan interest deduction?
The vehicle must be new (not used), for personal use, and have undergone final assembly in the United States. You can confirm U.S. final assembly using the vehicle's VIN through the NHTSA VIN decoder. The loan must be secured by the vehicle and generally must have originated after December 31, 2024.
Does leasing a car qualify?
No. The deduction applies to interest on a purchase loan secured by the vehicle. Lease payments and lease-financing charges do not qualify.
Can I claim this if I take the standard deduction?
Yes. Unlike home mortgage interest, the car loan interest deduction is claimed on Schedule 1-A, so you can take it whether you itemize or use the standard deduction.
