Check your VIN
Your VIN stays in your browser. Nothing is sent to our servers - it goes only to NHTSA's public VIN decoder.
Model-year note. The deduction depends on the loan date and the vehicle, not on the model year. A new GLS bought in 2026 with a 2026 loan still qualifies for 2026, 2027 and 2028 interest, however old the design is.
Why we say that
The interest on a car loan is deductible only if the vehicle was finally assembled in the United States. Our answer for the 2026 Mercedes-Benz GLS comes from the manufacturer's own Part 583 (American Automobile Labeling Act) filing to NHTSA, which states the final assembly countries for each carline. The MY2026 report lists the United States .
Because NHTSA's filing lists the United States, the final-assembly test is met for this carline. That still leaves the "new vehicle", "personal use", "loan date" and "first lien" tests, which depend on you and your paperwork - use the VIN checker for the vehicle tests and the six-point checklist for the rest.
What you must still confirm yourself
- New. Your use has to be the first use after it is sold, registered or titled.
- The loan. Taken out after December 31, 2024, for the purchase, secured by a first lien.
- Personal use. More than 50% of the expected use, personal.
- Filing. The VIN must appear on Schedule 1-A, Part IV - otherwise no deduction.
