Does the GMC Sierra 2500HD 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 2500HD is built and what it means for your loan interest.

PASS — assembled in the USA
The GMC Sierra 2500HD qualifies on the assembly test. 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 2500HD/3500HD is built exclusively at GM's Flint Assembly plant in Michigan — GM's only other heavy-duty line, Oshawa in Ontario, builds the Chevrolet Silverado HD, not the GMC Sierra. So every US-market Sierra HD is US-assembled and clears the OBBBA final-assembly test. Financed new for personal use and under the income cap, its loan interest can be deductible.
Where the GMC Sierra 2500HD is assembled
| Assembly plant | Location | Assembly test |
|---|---|---|
| Flint Assembly | Flint, MI | ✓ United States |
Confirm the other three tests
A US-assembly PASS 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 2500HD made in the USA?
Yes. The Sierra 2500HD and 3500HD are built at GM's Flint Assembly plant in Michigan — a US final-assembly point that meets the assembly test.
Isn't some GM heavy-duty production in Canada?
GM builds Chevrolet Silverado HD trucks at Oshawa, Ontario, but the GMC Sierra HD comes from Flint, Michigan. So the Sierra HD itself is US-built — the Canadian line makes the Chevy, not the GMC.
Does using a 2500HD for work affect the deduction?
The OBBBA deduction is for personal use. A heavy-duty truck used mainly for business falls under separate business rules, not this one.
