When my spouse purchased a brand new Subaru Outback in March, the producer provided particular financing at 3.9% APR. We didn’t take it as a result of whereas we might hold our money in a cash market fund incomes 4%, the curiosity is taxable. The curiosity paid on the mortgage could be after-tax. It might be net-negative if we financed.
The brand new 2025 Trump tax regulation — One Large Stunning Invoice Act — made automobile mortgage curiosity deductible (with {qualifications} and limits). Had we identified this was coming, we’d’ve financed, however we will’t return now to get a mortgage and deduct the curiosity.
Solely New Automobiles Assembled within the U.S.
Not all automobile loans qualify for the brand new tax deduction. It have to be for a brand new automobile, not for a used automobile. It have to be for private use, not a business automobile.
Each electrical and gasoline-powered autos qualify. Automobiles, minivans, SUVs, pickup vans, and bikes all qualify, however the automobile should have had its last meeting within the U.S.
Her Subaru Outback would’ve certified as a result of it was assembled in Indiana. Some manufacturers and fashions have vehicles assembled each within the U.S. and out of doors the U.S. It will depend on the precise automobile you get from the dealership. You’ll be able to inform by the VIN. It was assembled within the U.S. if the VIN begins with a 1, 4, or 5.
Timing
The mortgage have to be taken out on the time of buy after December 31, 2024. Refinancing an present mortgage taken out earlier than January 1, 2025 doesn’t depend. Taking out a brand new mortgage now on a automobile you already personal free and clear doesn’t depend both.
We’re disqualified as a result of we already paid money on the time of buy.
In case your mortgage qualifies, refinancing it continues to qualify, however the brand new mortgage should not exceed the excellent stability of the earlier mortgage. In different phrases, no money out.
Revenue Restrict
You’re allowed to deduct as much as $10,000 in automobile mortgage curiosity in case your modified adjusted gross earnings (MAGI) is $100,000 or much less ($200,000 or much less for married submitting collectively). Married submitting individually nonetheless qualifies. The deduction phases out by 20% as your earnings goes up towards $150,000 (or $250,000 for married submitting collectively).

The $10,000 deduction restrict is ample for most individuals. A 5-year mortgage of $50,000 at 3.9% APR would incur lower than $2,000 in curiosity within the first yr and fewer but in subsequent years. There’s no restrict on the variety of vehicles or any most worth so long as the loans in any other case qualify.

Momentary Deduction
In case your automobile buy qualifies, your timing qualifies, and your earnings qualifies, you’re allowed to deduct automobile mortgage curiosity as much as the restrict every year between 2025 and 2028 (inclusive). In case you’re planning to purchase a brand new automobile in 2026, then you’ve solely three years left.
It’s a tax deduction, not a tax credit score. Deducting $2,000 in automobile mortgage curiosity reduces your taxable earnings by $2,000. It reduces your federal earnings tax by just a few hundred {dollars}, relying in your tax bracket.

Dealerships additionally lowered their low cost to the MSRP. We must pay $4,000 extra if we have been to purchase the identical automobile right this moment.
Paying the next worth prices far more than the tax financial savings from deducting the curiosity on a automobile mortgage.
