Does the Kia K4 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 Kia K4 is built and what it means for your loan interest.

FAIL — assembled outside the USA
The Kia K4 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
The Kia K4, which replaced the Forte, is built at Kia's Pesquería plant in Nuevo León, Mexico for the US and global markets — including the newer hatchback body style. Mexican assembly means the K4 fails the OBBBA US-assembly test.
Where the Kia K4 is assembled
The Kia K4 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 Kia K4 built?
At Kia México's Pesquería plant in Nuevo León, Mexico. Both the sedan and the hatchback are produced there.
Was the Forte built in the same place?
Yes, the outgoing Forte also came from Kia's Mexican plant, so the K4 didn't change the answer on US assembly.
Which Kia sedan is US-assembled?
The K5 is built at Kia Georgia in West Point, GA. Confirm any specific car with the VIN — a 3 prefix means Mexico and a 5 means the US.
