⚠️ This calculator provides estimates for informational and educational purposes only. It is not tax advice. Results are based on the One Big Beautiful Bill Act (OBBBA) and IRS Schedule 1-A. Consult a qualified tax professional for your specific situation.
Qualification Rules That Decide It
Straight answer: the statute covers qualifying vehicles, and the interpretive question is whether your bike's classification falls in the covered class of motor vehicles. US-assembled cruisers with proper vehicle titles are the strongest case; run the numbers here, then confirm with your tax pro before counting on it. The dollar stakes are small, which is why the honest answer is worth more than a hopeful one.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Dex financed a US-assembled Harley and pays about $900 a year in interest.
- • Deductible amount: $900
- • Federal income tax savings: $108 (at the 12% marginal rate)
- • Per biweekly paycheck: $4
That repeats every year of the loan — interest deducts annually, which is why the loan-vs-lease math changed under OBBBA.

Frequently Asked Questions
Do motorcycle loans qualify for the OBBBA deduction?
It depends on the vehicle class: the deduction targets qualifying motor vehicles as defined in the statute, and many motorcycles fall outside the covered class. US assembly alone does not guarantee qualification — verify your bike's classification before claiming.
Do I need to itemize deductions to claim the car loan interest deduction?
No. Like the other OBBBA deductions, vehicle loan interest is an above-the-line adjustment on Schedule 1-A — it stacks on top of the standard deduction.
