Does the GMC Sierra 1500 qualify for the car loan interest deduction?

The 2025–2028 deduction turns on where a vehicle is finally assembled — not the badge. Here's where the 2025–2026 GMC Sierra 1500 is built and what it means for your loan interest.

DEPENDS — assembly varies by VIN

The GMC Sierra 1500 may qualify, depending on your VIN. Assembly is one of four gates — you also need a new vehicle, personal use, a 2025–2028 loan, and income under the phase-out.

The short answer

The GMC Sierra 1500 rolls out of US plants in Indiana and Michigan, but — like the Chevrolet Silverado it shares a line with — some are built in Mexico and Canada. Because a given truck could come from either side of the border, the Sierra only clears the OBBBA assembly test when your VIN decodes to a US final-assembly point.

Where the GMC Sierra 1500 is assembled

Assembly plant	Location	Assembly test
Fort Wayne Assembly	Roanoke, IN	✓ United States
Flint Assembly	Flint, MI	✓ United States

⚠️ Sierra 1500s are built at US plants (Fort Wayne, IN and Flint, MI) but also in Mexico and Canada, mirroring its Silverado twin. Final assembly varies by unit, so the VIN decides.

Confirm the other three tests

A US-assembly result is only the first gate. Each remaining condition has its own guide:

New & personal-use — used cars and leases don't qualify→ Loan dated 2025–2028 — refinancing keeps eligibility→ Income under the phase-out — run the MAGI calculator→

Frequently asked questions

Is the GMC Sierra 1500 made in the USA?

Some are. Fort Wayne, Indiana and Flint, Michigan build Sierras, but others are assembled in Mexico and Canada. The VIN tells you which applies to your truck.

Which Sierra 1500 VINs pass the assembly test?

VINs whose final-assembly country decodes to the United States pass; Mexican- or Canadian-built units fail. Our checker reads this straight from the VIN.

Does the Sierra's cab or trim affect where it's built?

Plant assignment can vary by cab and trim, which is exactly why you shouldn't assume — decode the specific VIN before relying on the deduction.
