If I purchased a new car in December 2025 (traded in), but have not had any monthly payments yet , can it still be added to 2025 taxes?

There is a new deduction for car loan interest, but if you did not make any payments in 2025 there is nothing to put on your 2025 tax return because you did not pay any interest in 2025. If the car meets the requirements for the deduction, then on your 2026 tax return you will be able to deduct the interest that you pay in 2026, up to a maximum of $10,000. Note that the deduction is only for the portion of your payments that is interest, not the entire payment. You will also be able to claim the deduction on your 2027 and 2028 tax returns for interest that you pay in those years.

The $10,000 maximum is gradually reduced if your Modified Adjusted Gross Income (MAGI) is over $100,000 (over $200,000 for Married Filing Jointly). The deduction is completely eliminated if MAGI is $150,000 ($250,000 MFJ) or more.
