Frequently Asked Questions
Can I deduct interest on a bad-credit car loan?
Yes — the deduction doesn't grade your credit. Interest on a qualified vehicle loan is deductible up to $10,000.
Buy-here-pay-here financing — does it count?
If the interest is stated and reported (1098 or loan statement), yes. Verify you receive loan documents showing interest paid.
