Schedule 1-A phrasing
No tax on car loan interest
Direct answer: “No tax on car loan interest” is the IRS Schedule 1-A label for the federal deduction of qualified passenger vehicle loan interest for tax years 2025–2028—up to $10,000 per return, with a MAGI phase-out—not a separate credit or a blanket rule that all auto loan interest is untaxed.
