## What’s New: Car-Loan Interest Deduction under OBBB
Starting for loans incurred **after December 31, 2024**, the One, Big, Beautiful Bill (OBBB) allows taxpayers to deduct interest paid on certain passenger-vehicle loans. Eligible vehicles must have undergone final assembly in the U.S., be for personal use, with a loan secured by the vehicle.

Thresholds apply: modified adjusted gross income (MAGI) must be under $100,000 (single) or $200,000 (filing jointly), with the deduction capped at $10,000 annually.

## Transition Relief for 2025
Lenders and interest recipients have temporary relief: for 2025, they meet reporting requirements if they simply make available to borrowers the total interest amount via an online portal, statement, annual summary or similar means. Penalties for information returns or statements won’t apply if these rules are followed.

## Planning Tips: What You Should Do Now
- **Check eligibility before purchasing**: Ensure the vehicle’s final assembly was in the U.S. (info found on the label or via VIN). Vehicles above 14,000 lbs or used vehicles don’t qualify.

- **Track interest paid in 2025**: Even if full compliance isn’t yet required from lenders, keep good records—monthly statements, online portals—so you have verifiable summaries when filing.
- **Mind your income limits**: If your MAGI is close to or above the thresholds, understand how phase-out rules work. If you expect higher income in later years, the deduction in those years may shrink.
- **Use the deduction with non-itemizers**: This deduction applies even if you don’t itemize—meaning standard deduction users can still benefit.
## Example Scenario
Suppose you’re a single filer with MAGI $90,000. You borrow $25,000 in 2025 for a new SUV (assembled in Michigan). Interest paid for the year: $1,500. You record monthly statements with interest paid and make sure your lender’s portal shows total interest. When you file your 2025 tax return, you subtract $1,500 as the car-loan interest deduction—saving tax at your marginal rate. There’s no need to itemize.
If instead your MAGI was $110,000, because of phase-out rules, your deduction would be reduced; knowing your MAGI early could influence whether you accelerate or delay such vehicle purchases.
## Risks & Common Missteps
- Buying a used vehicle or a vehicle assembled abroad: *no deduction*.
- Forgetting to include the VIN or proof of assembly.
- Lenders forgetting to provide accurate statements—during 2025 the relief is generous, but documentation must still be good enough for IRS review.
## Take-Action Checklist
- Confirm the vehicle’s eligibility via VIN or manufacturer label.
- Gather your statements or portal summaries showing total interest paid.
- Track your MAGI to see if the full deduction or a reduced amount applies.
- Include VIN and any required information on your tax return.
**Bottom line**: If you plan a car purchase in 2025, this new provision offers meaningful savings—especially if under the income thresholds. Act soon and document everything to make sure you qualify.
