Does the Mazda CX-90 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-90 is built and what it means for your loan interest.

FAIL — assembled outside the USA
The Mazda CX-90 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
Mazda's three-row CX-90 is assembled at the Hofu plant in Yamaguchi, Japan and shipped to the US, so it fails the OBBBA final-assembly test. Its smaller sibling the CX-50 is the Mazda that's actually US-built.
Where the Mazda CX-90 is assembled
The Mazda CX-90 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
Where is the Mazda CX-90 built?
At Mazda's Hofu plant in Yamaguchi Prefecture, Japan. Every US-market CX-90, including the PHEV, is imported.
Does the CX-90 PHEV qualify?
No. Plug-in or not, the CX-90 is assembled in Japan, and the deduction depends on US assembly rather than the powertrain.
Is the CX-70 built anywhere different?
The CX-70 shares the CX-90's Japanese production base, so it doesn't clear the assembly test either. Confirm any specific vehicle by decoding its VIN — a J prefix means Japan.
