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 maintain our money in a cash market fund incomes 4%, the curiosity is taxable. The curiosity paid on the mortgage can be after-tax. It could be net-negative if we financed.

The brand new 2025 Trump tax regulation — One Huge Stunning Invoice Act — made automotive mortgage curiosity deductible (with {qualifications} and limits). Had we identified this was coming, we might’ve financed, however we are able to’t return now to get a mortgage and deduct the curiosity.
Solely New Vehicles Assembled within the U.S.
Not all automotive loans qualify for the brand new tax deduction. It should be for a brand new automotive, not for a used automotive. It should be for private use, not a business automobile.
Each electrical and gasoline-powered autos qualify. Vehicles, minivans, SUVs, pickup vehicles, and bikes all qualify, however the automobile should have had its ultimate 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 automobiles assembled each within the U.S. and out of doors the U.S. It is dependent upon the precise automotive 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 should be taken out on the time of buy after December 31, 2024. Refinancing an current mortgage taken out earlier than January 1, 2025 doesn’t depend. Taking out a brand new mortgage now on a automotive 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.

Revenue Restrict
You’re allowed to deduct as much as $10,000 in automotive 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).
