Does the Mazda CX-30 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 Mazda CX-30 is built and what it means for your loan interest.

FAIL — assembled outside the USA
The Mazda CX-30 does not qualify 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
North American CX-30s are built at Mazda's Salamanca plant in Guanajuato, Mexico, with other markets served from Hiroshima, Japan. Neither is a US plant, so the CX-30 fails the OBBBA final-assembly test.
Where the Mazda CX-30 is assembled
The Mazda CX-30 is imported for the US market — its final assembly point is outside the United States, so it fails the assembly test regardless of the brand.
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 Mazda CX-30 made in America?
No. CX-30s for the US come from Salamanca, Mexico. Mazda's only US plant, in Huntsville, Alabama, builds the CX-50 instead.
What's the difference from the CX-50 here?
The CX-50 is assembled at Mazda Toyota Manufacturing in Huntsville, Alabama and clears the US assembly test. The CX-30 is Mexican-built and does not.
Does the turbo CX-30 change the answer?
No. All CX-30 trims sold in the US come from the same Mexican plant, so every version fails the assembly test.
