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.
