This tax season introduces a new deduction that might catch some people’s attention. Starting in 2025, those purchasing a new car could deduct the interest on their auto loans in certain situations. It’s, um, interesting for many buyers, I think.
The creation of this credit comes from the One Big Beautiful Bill Act, which also did away with taxes on tips and overtime for eligible workers. However, it also eliminated the tax credit for electric vehicle purchases for new buyers. It’s, well, a mixed bag for sure.
This deduction only applies to new cars bought after December 31, 2024.
If you took out your loan before then, unfortunately, you won’t qualify for this benefit. And, if you’re looking at buying a used car, you’re out of luck as well. It’s a shame, particularly since those with poor credit tend to face the highest interest rates when buying used cars—so, yes, it feels a bit unfair.
On the bright side, if you do manage to buy a new car in 2025, there’s still more to explore.
Not everyone can benefit.
This deduction phases out for single taxpayers with a modified adjusted gross income (MAGI) exceeding $100,000. For those married and filing together, the phaseout starts at $200,000. However, hitting those numbers doesn’t entirely exclude you. Depending on your MAGI and certain deductions, you might still see some benefit, which is, well, something to hang onto.
Your vehicle must be assembled in the U.S.
To qualify for this deduction, it’s essential that your vehicle be assembled in the U.S. Mark Gallegos, who’s a tax partner at Port Brown Wealth Management, often has to remind his clients that buying a “Made in the USA” car can be risky. Global companies may have assembly plants here, but that doesn’t necessarily mean the car was fully made domestically. Checking the VIN is crucial, he advises.
Plus, the vehicle must be for personal use, not for a business. Just keep that in mind.
If all conditions align, you can deduct up to $10,000 in interest.
This tax season, it’s imperative to look through your auto loan documents closely and note the total interest paid in 2025. Interestingly, your lender won’t send you separate tax info, which could catch some off guard.
Gallegos emphasizes that a deduction is distinct from a tax credit. A tax credit reduces the taxes you owe directly, whereas a deduction just lowers your taxable income. So, if you deduct $1,000 in interest, it doesn’t mean you’ll pocket that entire amount—how much you save depends on your tax bracket.
You can get this deduction even with the standard deduction.
Unlike some tax credits that don’t apply if you take the standard deduction—like the mortgage interest deduction—this new provision is inclusive. Gallegos thinks that’s a significant benefit, opening the door for more taxpayers.
Don’t expect this to radically boost domestic manufacturing.
During the Biden administration, considerable efforts went into encouraging domestic manufacturing, especially for electric vehicles. While hefty tax deductions for American-made EVs motivated companies to establish plants in North America, those tax credits have now vanished. The Trump administration has introduced high tariffs on international car parts, which creates pressure, but will this new tax credit bring much change? Probably not, says Ivan Drury, who heads insights at an automotive data firm.
Yes, it’s geared toward U.S.-assembled cars, but Drury argues it doesn’t move the needle significantly, especially since it won’t benefit those who lease or those who secured 0% financing. For some buyers, it might be helpful, but Drury points out it’s more of a nice addition than a deciding factor when comparing U.S. manufactured cars with foreign options.
Ultimately, manufacturers aren’t likely to shift production plans dramatically for this tax credit alone. Yet, Drury notes, this could provide a slight economic boost for certain buyers, which, well, isn’t such a bad outcome overall. Even if one doesn’t qualify, it’s not as though the overall situation worsens.
