When do I receive Form 1098-VLI?

Lenders are required to send Form 1098-VLI by January 31 of the following year. So for 2025 tax year interest, you should receive it by January 31, 2026.

Can I deduct auto loan interest from state taxes too?

It depends on your state. The federal deduction is on Schedule 1-A. Some states conform to federal tax changes automatically, while others don't. Check your state tax authority's guidance.

What if I paid off my auto loan early?

You can deduct the interest you actually paid during the tax year, even if you paid off the loan early. The deduction covers interest paid, not interest owed.

Can both spouses claim the deduction?

If filing jointly, the $10,000 cap applies to your combined return. If filing separately, each spouse can claim up to $10,000 for their own qualifying vehicle loans, but the income phase-out threshold drops to $100,000 each.

Step-by-Step: Calculating Your Auto Loan Interest Deduction

Step 1 — Determine your annual interest paid. Check Form 1098-VLI from your lender, or calculate it using our tool above.

Step 2 — Apply the $10,000 cap. If you paid less than $10,000, your full interest amount is potentially deductible. If more, cap it at $10,000.

Step 3 — Check for income phase-out. Compare your MAGI to the threshold for your filing status. If you're under the threshold, skip to Step 4. If over, calculate the reduction: (MAGI - threshold) ÷ 1,000 × $200.

Step 4 — Subtract the phase-out reduction from your capped amount. This is your final deduction.

Step 5 — Multiply by your marginal tax rate to determine your actual tax savings.

Common Mistakes to Avoid

Claiming the deduction for a used vehicle — only new vehicles qualify
Forgetting the U.S. assembly requirement — not all new cars qualify
Missing the Form 1098-VLI — if your lender doesn't send it by February, contact them
Confusing business and personal use — if you use the vehicle for business, you may need to choose between this deduction and business vehicle deductions
Not accounting for the phase-out — higher-income taxpayers often overestimate their deduction
