The 1098-Auto Alert: Why Your Car Lender is Required to Send This New Tax Form by January 31st

If you’ve been checking your mailbox for your usual W-2s and 1099s, keep an eye out for a newcomer this January: Form 1098-Auto (officially appearing in some systems as Form 1098-VLI). This brand-new tax document is a direct result of the One Big Beautiful Bill Act (OBBBA), and for millions of Americans who financed a vehicle in 2025, it is the golden ticket to a significantly lower tax bill.

Under the new federal mandates, any commercial lender that received $600 or more in interest on a qualified vehicle loan during the 2025 calendar year is legally required to furnish a statement to the borrower by January 31, 2026. If you financed an American-made car last year, this form is the proof you need to claim the OBBBA’s landmark $10,000 car loan interest deduction. Here is why this form is hitting your mailbox this week and what you need to do with it.

The “1098-Auto” vs. “1098-VLI” Confusion

As with many new laws, the nomenclature is still settling. While consumer advocacy sites and banks are referring to it as the 1098-Auto, the IRS draft forms are labeled 1098-VLI (Vehicle Loan Interest). Regardless of the heading, the purpose is the same: it functions exactly like the Form 1098 you receive for your mortgage interest.

According to IRS Notice 2025-57, the government provided “transition relief” for the 2025 tax year. This means that while some lenders may send you a formal, government-looking form, others are permitted to send a “simple statement” or provide the data via their online portal. As long as the document clearly states the total interest paid and the VIN of the vehicle, it is valid for your 2026 filing.

Why $600 is the “Magic Number”

You might be wondering why you received a form for your truck but not for your spouse’s sedan. The OBBBA reporting requirement only triggers when a borrower pays at least $600 in interest during the tax year. As noted by EY Tax Services, with 2025 interest rates hovering between 6% and 9% for many buyers, it doesn’t take a massive loan to hit that $600 threshold.

If you had a $30,000 loan at 7% interest, you likely paid over $2,000 in interest in your first year alone. If your interest was under $600, your lender isn’t required to send the form, but you may still be able to deduct the interest—you’ll just have to calculate it yourself using your monthly statements.

The 3 Crucial Boxes to Check

When your 1098-Auto arrives, don’t just hand it to your tax preparer. You need to audit three specific boxes to ensure you don’t trigger an automatic IRS flag:

Box 1 (Interest Received): This is the amount you will enter on your return. It should only reflect interest, not principal or late fees.
Box 2d (VIN): The 17-digit Vehicle Identification Number must be present. The IRS uses this to verify that the car was “finally assembled” in the United States.
Box 3a (Origination Date): The loan must have originated after December 31, 2024. If your lender accidentally reports a loan from 2024, the IRS AI will reject the deduction.

“Above-the-Line” Power

The reason the 1098-Auto is so valuable is that the car loan interest deduction is “above-the-line.” Unlike most deductions that require you to have a massive pile of receipts to beat the standard deduction, this one is available to everyone. According to H&R Block, you can claim this even if you take the standard deduction.

By using the information on your 1098-Auto to fill out Schedule 1-A, you lower your Adjusted Gross Income (AGI) directly. This can have a “waterfall effect,” potentially making you eligible for other credits—like the Child Tax Credit or the Earned Income Tax Credit—that you might have otherwise phased out of.

What if the Form Doesn’t Arrive?

Lenders have until midnight on January 31st to postmark these forms. If you haven’t seen yours by February 10th, your first step should be to log in to your auto lender’s website and check the “Tax Documents” or “Statements” section. Because 2026 is the first year for this requirement, many smaller credit unions and regional banks are struggling with the new software.

As Jackson Hewitt advises, if your lender fails to provide a form, you can still claim the deduction by using your final December 2025 monthly statement, which should show the “Year-to-Date Interest Paid.”

Don’t File Too Early

The 1098-Auto is a powerful tool for middle-class savings in 2026, but it’s also a brand-new system. If you file your taxes in mid-January before this form arrives, you might miss out on a deduction worth thousands of dollars. Wait for the 1098-Auto, verify the VIN, and make sure your lender hasn’t left you in the lurch. This little piece of paper is the key to turning your car payment into a tax refund.
