USA CAR Act

Introduced: May 7, 2025
Economy & Taxes
Standard Summary
Comprehensive overview in 1-2 paragraphs

The USA CAR Act would create a new tax deduction for interest paid on loans used to buy certain automobiles. Specifically, individuals could claim an above-the-line deduction (i.e., a deduction that reduces adjusted gross income) for the portion of interest paid on indebtedness incurred after enactment that is used to acquire a “qualified automobile,” with the loan secured by the automobile. A “qualified automobile” is an automobile whose final assembly occurs in the United States, as defined by the Automobile Information Disclosure Act. The deduction would be in addition to other deductions and would apply to interest on new debt (incurred after enactment). The bill sets up the definition of qualified automobile interest and narrowly ties eligibility to US-assembled vehicles. In short, if enacted, the bill would lower the after-tax cost of buying certain US-assembled cars by allowing taxpayers to deduct the interest paid on the car loan from their gross income, starting with loans incurred after the law’s enactment.

Key Points

  • 1Creates a new above-the-line deduction (Section 62(a)(22)) for qualified automobile interest, starting with debt incurred after enactment.
  • 2Defines “qualified automobile interest” as interest paid or accrued in the tax year on indebtedness that (a) is incurred after January 1, 2025, (b) is used to acquire a qualified automobile, and (c) is secured by that automobile.
  • 3Defines a “qualified automobile” as a car that is, per the Automobile Information Disclosure Act, manufactured such that the final assembly occurs in the United States. Final assembly is described as the process by which the car is produced at a plant or facility from which it is delivered to a dealer with all necessary mechanical components.
  • 4The deduction applies only to individuals (not corporations) and is limited to the portion of interest attributable to qualified automobile indebtedness.
  • 5Effective date specifies the amendments apply to amounts paid or accrued on indebtedness incurred on or after the enactment date.

Impact Areas

Primary group/area affected: Individual taxpayers who take out loans to purchase US-assembled automobiles and want to reduce their taxable income.Secondary group/area affected: U.S. automobile manufacturers and domestic assembly facilities, which may benefit if the policy increases demand for cars with US final assembly.Additional impacts: Potential revenue impact to the U.S. Treasury from reduced taxable income, incentives for lenders and borrowers around auto loans, and a possible shift in consumer behavior toward vehicles that qualify under the US final-assembly criterion. The rule could create incentive to purchase vehicles that qualify under the specified definition, potentially affecting the mix of imported versus domestically assembled cars.
