A new tax deduction lets you write off up to $10,000 per year in car loan interest. Most people buying a car right now have no idea this exists. If you financed a new vehicle in 2026 and you are under the income threshold, this is real money – potentially $1,500 to $2,200 back in your pocket depending on your tax bracket.
The deduction comes from the One Big Beautiful Budget Act, signed into law in 2025. According to IRS OBBBA guidance 2026, it allows taxpayers to deduct interest paid on loans for new, qualifying passenger vehicles. It runs through the 2028 tax year, then sunsets. After that, it is gone unless Congress acts.
The vehicle has to be assembled in the United States. That is not negotiable. A car built in Mexico or Canada does not qualify, even if it is a major American brand. You can verify assembly location using the VIN lookup tool at FuelEconomy.gov before you buy. This one requirement knocks out a significant portion of the new car market.
The income phase-out starts at $100,000 for single filers and $200,000 for joint filers, according to IRS OBBBA guidance 2026. The deduction does not disappear immediately at those numbers – it phases out gradually above those thresholds. But if you are well above them, run the math before assuming you qualify for the full amount.
Here is what the deduction is actually worth. The average new car loan payment hit $736 per month in 2026, per FinanceBuzz OBBBA tax changes reporting. In year one of a loan, the interest portion of that payment runs roughly $180 to $300 per month depending on rate and loan size. That is $2,160 to $3,600 in annual interest. At a 22 percent federal tax rate, deducting $3,600 saves you roughly $792. At the full $10,000 cap, you save $2,200 at the 22 percent bracket.
To claim it, you need the annual interest statement from your lender, similar to a mortgage Form 1098. Not all lenders are issuing this automatically yet, according to Empower financial planning guide 2026. Call your lender and ask for your total interest paid for the year before you file. Use the Ohio take-home pay calculator to model how the deduction changes your effective net income after taxes.
This deduction is available right now, it has a hard expiration date, and a meaningful slice of buyers who qualify are not claiming it. Check your VIN, check your income, call your lender, and keep the paperwork.
