DETROIT — A new federal tax break aimed at helping Americans afford new cars is now in effect—but for Michigan drivers, the fine print may come as a shock.

The 2025 tax law allows buyers to deduct up to $10,000 a year in interest on auto loans, but only if the vehicle meets strict requirements—including one that is already tripping up many shoppers:

The car must be assembled in the United States.

That rule was designed to boost American manufacturing. But in a global auto industry—even in Michigan—it creates confusion and unexpected exclusions.

Michigan Reality Check: Which Cars Qualify

Here’s where it gets interesting—and where your story gets real traction.

Likely to Qualify (U.S.-assembled models)

These vehicles are assembled in the U.S. and generally meet the key requirement:

  • Ford F-150 (Michigan-built)

  • Ford Mustang (gas version) (Michigan-built)

  • Chevrolet Silverado (U.S. plants)

  • Cadillac lineup (largely U.S.-assembled)

  • Tesla Model Y / Model 3 (U.S.-built)

  • Honda Civic (select U.S.-built versions)

  • Toyota Camry (Kentucky-built)

Even some “foreign” brands qualify—because what matters is where the car is built, not who owns the company.

May NOT Qualify (even from Detroit automakers)

Here’s the twist—and your strongest hook:

  • Ford Mustang Mach-E (built in Mexico)

  • Many Chevrolet models (less than half are U.S.-assembled)

  • Most Buick vehicles (majority built outside the U.S.)

  • Numerous entry-level or lower-cost cars (often imported)

That means a Michigan buyer could walk into a dealership, pick a Detroit brand—and still miss out on the tax break.

Why This Matters More in Michigan

Michigan isn’t just another state—it’s the heart of the U.S. auto industry.

But today’s vehicles are built through global supply chains:

  • Some “American” cars are assembled overseas

  • Some “foreign” cars are built in U.S. factories

The result: buyers must check the window sticker—not the logo.

The IRS says eligibility is determined by the vehicle’s final assembly location listed on the label.

How Much Will You Actually Save?

The $10,000 figure grabs attention—but here’s the reality:

  • It applies only to interest, not the full loan

  • Average savings: a few hundred dollars per year

  • Typical estimate: about $400 annually depending on loan terms

So yes—it helps. But it’s not a game-changer.

Who Qualifies Financially

Not everyone gets the full benefit:

  • Full deduction under $100K income (single)

  • $200K for couples

  • Phases out above that

The program runs from 2025 through 2028.

This isn’t a blanket tax break—it’s a targeted industrial policy.

And for Michigan drivers, the takeaway is blunt:

Not every Detroit car qualifies—and some “foreign” cars do.

If you’re buying a new vehicle this year, one simple step could save—or cost—you money:

👉 Check where it’s assembled before you sign.
