Assembly
US final assembly is required for the qualified passenger vehicle loan
Free VIN check · US assembly
Free VIN check — was it assembled in the US?
Paste the 17-character VIN. This reads NHTSA PlantCountry. It is a data check, not tax advice, and it does not decide whether any loan is deductible.
The Internal Revenue Service and the 2026 Internal Revenue Code both treat final assembly in the United States as a gate for the qualified passenger vehicle loan. IRS Topic 505 says the vehicle’s “final assembly must occur in the United States.” 26 U.S.C. § 163(h)(4)(A)(ii) says a qualified passenger vehicle must have had “its final assembly occur within the United States.”
What “final assembly” means in this context
The Code and Topic 505 use final assembly, not “designed in America,” “union-built,” or “has a U.S. headquarters.” A vehicle can carry a U.S. brand and still have been assembled in Canada, Mexico, or another country. A vehicle can carry a foreign brand and still have been assembled in a U.S. plant.
AssemblyAlert’s official-record check is plant of manufacture from NHTSA’s Product Information Catalog and Vehicle Listing (vPIC). That is the same public decoder the National Highway Traffic Safety Administration publishes for VIN lookups. It is not an IRS ruling that your particular loan is a qualified passenger vehicle loan.
What it means for filers
If you are assembling records for a possible 2025–2028 return:
- Run the VIN through an official-record decoder.
- Read Plant Country / plant of manufacture. AssemblyAlert maps that field to a sealed assembled-in-the-United-States or not assembled in the United States verdict.
- Keep the VIN for the return. Schedule 1-A asks for the VIN in Part IV.
- Do not treat a U.S. plant result as “you qualify.” Income, original use, lien, personal use, GVWR, and the tax year still sit with you and a tax professional.
Common misconceptions
“Made in America” window stickers settle it. Marketing copy, content percentages, and union-plant ads are not the statutory test. The statute says final assembly.
“Import brand means foreign assembly.” Many nameplates assemble vehicles in U.S. plants. Decode the VIN.
“AssemblyAlert decides my deduction.” No. The sealed verdict is assembly-only. See how we read Plant Country.
“I can skip the VIN if I have a window sticker.” The IRS form still wants the VIN. See VIN on the return.
How AssemblyAlert’s VIN checker and calculators relate
The free checker on this page and the homepage checker call `/api/decode`, which queries NHTSA vPIC. Paid VIN reports add a downloadable official-record PDF. They still do not say a loan is deductible.
The interest / MAGI calculators assume you already know the assembly and other statutory pieces. They do not replace a vPIC decode.
If you are comparing two VINs from the same shopping trip, decode both. Plant country can differ across trims and model years of the same nameplate.
