Who gets it, and how much?

Who qualifies

  • Interest on a loan for a new car, minivan, van, SUV, pickup or motorcycle under 14,000 pounds, bought for personal use, with its final assembly in the United States.
  • The loan must be taken out after December 31, 2024, and secured by the vehicle. Used cars and leases do not count; a qualifying loan you refinance still does.
  • You put the vehicle’s VIN on your return.
  • You get it whether you take the standard deduction or itemize.

How much

  • Up to $10,000 of interest a return.
  • It shrinks by $200 for each $1,000 (or part of $1,000) of income over $100,000 ($200,000 married filing jointly), so it is gone at $150,000 ($250,000).

When

  • Tax years 2025 to 2028 only, unless Congress extends it.
