Car Loan Interest Deduction Calculator (No Tax on Car Loans)

Good to know: Scope: the federal deduction for qualified passenger vehicle loan interest (“no tax on car loans”) on Schedule 1-A (Form 1040), Part IV, for tax years 2025 through 2028. It follows the IRS form lines: the qualifying interest you paid in the year, minus any interest you already deduct on Schedule C, E or F, is capped at $10,000 per return; then for every $1,000 (or part of $1,000) that your modified adjusted gross income (MAGI) is over $100,000 ($200,000 if married filing jointly), $200 is taken off, not below $0. To qualify, the loan must be taken out after December 31, 2024 to buy a new vehicle for personal use (its original use starts with you), be secured by a first lien on that vehicle, and the vehicle must be a car, minivan, van, SUV, pickup truck or motorcycle with a gross vehicle weight rating under 14,000 pounds and final assembly in the United States. Leases, used vehicles, loans from a related person and business vehicles don’t qualify. The IRS list of deductions married couples filing separately can’t take names the tips, overtime and senior deductions but not this one, so separate filers use the $100,000 threshold here. Not included: checking a VIN for you, splitting a loan that also paid for negative equity, add-on insurance or cash back (only the vehicle part counts), how to figure MAGI beyond your adjusted gross income plus excluded foreign and territory income, state income tax, and the tips, overtime and senior deductions on the same schedule. The interest estimate uses a standard fixed-rate monthly loan schedule; your lender’s year-end statement is the number to file with. The tax saving is a rough estimate from the bracket you type. Nothing you enter is sent or saved. Independent ToolsKo estimate, not tax advice. Sources reviewed November 14, 2026.
