Tax Break on U.S.-Built Cars Aims to Boost Domestic Auto Sales and Save You Money!

New cars have gotten very expensive. So, if you’re looking for one, you might have run into a lot of frustration. Fortunately, there seems to be a light at the end of the tunnel with a new tax break. 

Starting in 2025 and lasting through 2028, the One Big Beautiful Bill Act allows individuals to deduct up to $10,000 of interest paid annually on auto loans. However, there are certain conditions to apply. 

The deduction is only for new cars that were finally assembled in the U.S., irrespective of whether they’re gasoline, hybrid, or electric vehicles. That’s a surprising factor, because EVs were affected by the ending of the $7,500 rebate from the previous administration. 

This is good news not only for the automotive industry, but also for you, the buyer. So, if you’re interested, here are the details of who can apply.

Who can qualify for the tax break on new cars? 

Here’s the list of people who can apply for the tax break on new cars. 

• Individuals with a modified adjusted gross income (MAGI) of up to $100,000 (or $200,000 jointly) can take the full deduction; beyond that, it phases out completely by $150K (single) and $250K (joint).
• Vehicles must be new (2025–2028), for personal use, and have been finally assembled in the U.S.
• The VIN must be reported, and the loan must be secured and not for used cars

Why it matters:

With the new car market changing so much, it’s crucial for prospective buyers to understand how they can take advantage of all these benefits. Not only that, but knowing which are the short and long-term benefits. 

The average interest on new car loans is hovering at around 8% (on a great deal) to 9% (on the market average). So, with this new tax break, buyers could see up to $400 in annual savings if they have a $2,000 interest bill. 

This situation also corresponds to policies that were promised during the campaign. As we’ve covered before, the idea is to prioritize domestic assembly while also providing benefits to the working class. This tax break checks both of these items. However, there is debate as to whether this could further increase federal deficits. 

There’s also another point of discussion and that is whether this tax deduction will offset the tariff impact on new cars. This ITEP analysis finds that this deduction won’t fully offset new tariffs on U.S. assembled vehicles. For a 5% price hike (about $2,000 on a $40K car), working‑class buyers would recover just 25% ($500).

Not only that, but the most impacted vehicles will be affordable cars. Most affordable cars are built overseas; as many as 80% of cars under $30K won’t qualify for the benefit. 

After all, finance costs, vehicle price, insurance, fees, and upkeep still matter immensely when evaluating total purchase cost.

So, having said all that, how does this deduction work for buyers?

How It Works for Buyers

Step	What to Know
1. Choose Car	Must be new, U.S.-assembled. Galvanizes support for auto‑makers like Ford, GM, Tesla, Stellantis.
2. Finance Loan	Ensure the loan is standard, secured, and VIN is recorded on tax return .
3. Claim on Taxes	Use the deduction even if you take the standard deduction—no itemizing needed .
4. Phase-out Brackets	Full benefit up to $100K/$200K MAGI; reduced beyond, gone by $150K/$250K .

Real-World Impact for Prospective Buyers 

This is great news for middle‑income buyers in their 30s and 40s who want American‑made trucks, SUVs, or pickups. For example, financing a $50,000 U.S.-built Ford or Chevy could yield hundreds in annual savings—an attractive win if paired with dealer incentives.

But given that tariffs on auto parts could raise prices by thousands, this tax break is more of a buffer than a full relief. Plus, the eligibility rules mean the benefit favors new, domestic vehicles, leaving out many affordable used and imported options.

So, what’s the bottom line? 

• Smart move? Yes, if you’re financing a new, U.S.-assembled vehicle and fall within income limits.
  
• Not a windfall: At best, it trims financing costs—won’t offset trade-driven price surges fully.
  
• Consider the bigger picture: Loan terms, total cost, and long-term ownership should still guide decisions—this isn’t a green light to buy beyond your budget. You can read our article on how to get the best rates here.
