Car Loan Interest Deduction: What Texas Buyers Should Know

The short answer

There's a new federal tax deduction for interest on a car loan, but it's narrower than the headlines suggest. According to the IRS, you may deduct up to $10,000 a year of interest on a loan to buy a new vehicle for personal use, if the loan originated after December 31, 2024, the vehicle had final assembly in the United States, and your income is under the phase-out limits. Used vehicles don't qualify. Lease payments don't qualify. It applies to tax years 2025 through 2028. I'm the Sales and Social Media & Marketing Manager at Kramer Autoplex, not a tax professional, so use this to ask better questions, and check with a tax preparer about your return.

I read the IRS fact sheet on the new deductions (FS-2025-03), IRS Publication 6126, and the final regulations the Treasury and IRS published in the Federal Register on September 8, 2026, which take effect on November 9, 2026, for this article.

What qualifies

From the IRS fact sheet and Publication 6126:

• A loan originated after December 31, 2024.
• A new vehicle. The IRS says the original use of the vehicle must start with you, and "used vehicles do not qualify."
• Personal use, not business or commercial use.
• Secured by a lien on the vehicle. The final regulations say a first lien.
• An eligible type of vehicle: a car, minivan, van, SUV, pickup truck, or motorcycle with a gross vehicle weight rating under 14,000 pounds.
• Final assembly in the United States.

The IRS says the location of final assembly is listed on the vehicle information label attached to each vehicle on a dealer's lot. You can also use the plant of manufacture in the VIN.

How much, and who gets it

• The maximum deduction is $10,000 a year. The final regulations say the limit is per return, regardless of filing status.
• It phases out when modified adjusted gross income is over $100,000 ($200,000 for joint filers). The final regulations describe the reduction as $200 for each $1,000 over the threshold.
• It's available to people who take the standard deduction as well as those who itemize.
• You must include the vehicle's VIN on your return in any year you claim it.
• If you refinance a qualifying loan, interest on the refinanced amount is generally still eligible.

What the final regulations clarify

A few points that matter for buyers, from the Federal Register document:

• Personal use means that, when you take out the loan, you expect the vehicle to be used for personal use by you, your spouse, or certain relatives for more than 50 percent of the time you expect to own it.
• The loan can include more than the vehicle's price. The regulations define the qualifying debt to include the cost of warranties, service plans, and other amounts customarily financed in a vehicle purchase and directly related to the vehicle.
• Interest recipients (lenders) that receive $600 or more of interest in a year on a covered loan have to report it. The regulations refer to Form 1098-VLI, and say that statement includes a legend noting you may not be able to deduct the full amount shown.
• Original use generally begins with the first person who takes delivery after the vehicle is sold, registered, or titled. For a loan, the loan paperwork must treat the vehicle as new.
• The IRS and Treasury declined requests to extend the deduction to used or nearly new vehicles, saying the statute requires original use to start with the taxpayer.
• A lease buyout generally doesn't qualify: the regulations say the original use of a leased vehicle commonly starts with the lessor, and the loan paperwork generally doesn't treat it as new.

What it means if you're shopping

Here's how I'd use it:

1. Ask where it was assembled. If you're buying new and want to know if it could qualify, look at the window label's final assembly point or the VIN, as the IRS describes. Treasury's own analysis in the final regulations estimates that about 60 percent of new vehicles sold in the U.S. undergo U.S. final assembly, so don't assume a given model qualifies.

2. Don't count on it for a used car. If you're buying used, the deduction doesn't apply, so build your budget without it.

3. Don't let it set your payment. A deduction reduces taxable income. It doesn't lower your monthly payment, and the savings depend on your income and tax situation. Compare loans on total cost, not a tax angle. Our guides on five numbers to check before signing a car loan and what you can negotiate on a car loan are good starting points.

4. Keep your records. You'll need the VIN, the purchase date, the loan documents, and the year-end interest statement from your lender.

5. Talk to a tax preparer about your own return, especially if your income is near the phase-out or the vehicle might see business use.

What this article isn't

• It isn't tax advice, and I don't know your tax situation. Deductions depend on your return.
• I'm not telling you any specific vehicle qualifies, and I'm not promising approval, a rate, or a monthly payment on any loan.
• Rules can change, and the final regulations are new. Confirm details with the IRS or a tax professional.

Bottom line

The car loan interest deduction exists, and it can be worth up to $10,000 a year, but only for qualifying new, U.S.-assembled, personal-use vehicles with a loan originated after 2024, and only if your income is under the limits. It doesn't help with used-car loans or leases. If you're financing a car, shop on the total cost of the loan first, and treat any tax benefit as a bonus you confirm with your preparer.

A same-day answer on where you stand, including what you qualify for and the monthly payment, is typical, not a guarantee of approval. The first step is just your name plus phone or email, about 20 seconds, with no credit check yet. The full application, which does involve a credit check, comes after.
