An equally important pivot that got eclipsed by the EV tax credit’s removal has suddenly resurfaced online. A new provision in President Trump’s One Big Beautiful Bill Act (OBBBA) signed into law in 2025 lets qualifying taxpayers deduct up to $10,000 per year in interest paid on a car loan for a new vehicle assembled in the United States.
The media hasn’t played as much attention to this provision as the discontinued EV tax credit. Perhaps that’s because, unlike Biden’s EV tax credit, this provision means you subtract that amount from your taxable income before calculating your tax bill. It does not work like a direct rebate or credit that reduces your tax bill dollar for dollar like the old federal electric vehicle credits did.
This deduction goes into effect for tax years 2025 through 2028 and is structured as an above-the-line deduction, meaning you can claim it even if you take the standard deduction instead of itemizing.
How This Differs from a Tax Credit
A tax credit, like the old EV credit, directly reduces the amount of tax owed. A deduction reduces your taxable income, so the taxpayer’s actual dollar benefit depends on how much interest was paid and the individual’s tax bracket.
For example, if someone paid $4,000 in qualifying auto loan interest and was in a 22% tax bracket, the deduction might reduce their taxes by around $880, not $4,000.
That’s the key distinction that was missing in the original headline shared on social media.
We want investments in America, not China.
The Trump Administration wants you to buy brand new cars made here which is why we are giving a 💲TEN THOUSAND DOLLAR tax credit to you if you buy a car made in the USA 🇺🇸 🚘 pic.twitter.com/QyAfFInmB5

The misinterpretation stems from a video posted on X by US transportation secretary Sean Duffy implying that the US government is offering $10,000 tax incentives for American auto shoppers to buy made in America. The post reads:
“The Trump Administration wants you to buy brand new cars made here which is why we are giving TEN THOUSAND DOLLAR tax credit to you if you buy a car made in the USA.”
X’s reader’s context pointed out the misrepresentation in Duffy’s claim.
Who Qualifies and What Vehicles are Eligible?
To benefit from the deduction:
- The vehicle must be new and assembled in the United States, with the buyer as the first owner. This excludes used or leased vehicles.
- The loan must be for personal use and secured by the vehicle.
- The final assembly must have been in the U.S. (often verified through the VIN or manufacturer data).
Eligible vehicles generally include cars, trucks, SUVs, vans, and motorcycles that weigh less than 14,000 pounds.
Furthermore, the benefit is not automatic for everyone. There are income phase-outs: as modified adjusted gross income (MAGI) rises above certain thresholds, the deduction shrinks and eventually goes away. For single filers, the phase-out begins around $100,000 and for joint filers around $200,000, with full phase-outs at higher levels.
This means someone with higher income might not get the full $10,000 deduction even if they qualify on the vehicle and loan requirements.
Real Impact for Car Shoppers
For many car buyers, the actual tax benefit will be modest relative to the cost of purchasing a new vehicle. Because the deduction only applies to interest paid, not the principal, and because most buyers pay much more toward principal than interest each year, a $10,000 cap doesn’t mean a $10,000 tax break in practice. Estimates suggest many buyers will see a few hundred dollars in tax savings per year rather than thousands.
The deduction will likely matter most to buyers who:
- Finance a significant portion of the vehicle cost at higher interest rates,
- Buy relatively expensive new cars that meet the U.S. assembly rule, and
- Are in tax brackets where deductions actually change their taxable income meaningfully.
Even then, it’s not a cash incentive at the point of sale. The savings come later when filing a tax return, and they depend heavily on personal tax situations.
Why the Story Spread So Fast
At press time, Duffy’s post has generated over 578,000 views and retweeted 2,700+ times. The confusion stems from how appealing a “$10,000 tax break” sounds in a headline. But the nuance matters: it’s a deduction on loan interest, not a tax credit on the purchase price. When amplifying this story, it’s important to emphasize the distinction to help audiences understand the real economic benefit — and set realistic expectations for car shoppers.
