Car Loan Interest Deduction Now Tied to U.S. Final Assembly

New tax guidance now allows car buyers to deduct interest on auto loans, but only for vehicles that were finally assembled in the United States. The provision is designed to encourage domestic production, though it may surprise shoppers who assumed the deduction applied to any new car regardless of where it was built.

Eligibility is not based on a brand’s country of origin. Rather, the rule looks at where the specific vehicle’s final assembly took place. Buyers should not rely on a nameplate alone, since many models are built in multiple plants across different countries. The requirement is straightforward: the final assembly must have occurred within the U.S.

To check a car’s eligibility, the VIN is the most reliable tool. The 11th character of the VIN identifies the assembly plant, and the window sticker also lists the final assembly point. Additionally, dealerships can confirm this information, and buyers can look up VIN details online. It’s a quick step that can prevent a tax surprise later.

Before planning a purchase around the deduction, confirm that the car meets the final-assembly requirement. Even a popular domestic-brand model may not qualify if it was assembled overseas. For clarity on how the deduction applies to your specific situation, consult a tax professional. The rule is new, so ensure you have the latest guidance.
