How This Calculator Works
Calculation methodology and assumptions
The "No Tax on Car Loan Interest" deduction (26 U.S.C. Sec. 163(h)(4)), added by the One Big Beautiful Bill Act (Pub. L. 119-21, Sec. 70203) for tax years 2025 through 2028, lets eligible borrowers deduct up to $10,000 per year of interest on a qualifying new-vehicle loan -- whether or not they itemize. To qualify, the loan must have originated after December 31, 2024, be a first lien securing the vehicle (lease payments never qualify), and finance an "applicable passenger vehicle": one whose original use begins with you (used vehicles don't qualify), with at least 2 wheels, that is a car, minivan, van, SUV, pickup truck, or motorcycle, has a gross vehicle weight rating under 14,000 lbs, and underwent final assembly in the United States (check the vehicle's window sticker or run the VIN through NHTSA's VIN decoder). The vehicle must also be for personal use -- you must expect it to be used more than 50% of the time for personal (non-business, non-investment) purposes. The deduction (after the $10,000 cap) is reduced, but not below zero, by $200 for every $1,000 -- rounding UP any partial $1,000 -- that your Modified Adjusted Gross Income (MAGI) exceeds $100,000 ($200,000 if married filing jointly), fully eliminating it at $150,000 MAGI (single/HOH/MFS) or $250,000 MAGI (joint). Unlike the tips, overtime, and senior deductions in this same cluster, there is no requirement that married taxpayers file jointly to claim this one -- Married Filing Separately uses the same $100,000 threshold as Single/Head of Household. Neither the $10,000 cap nor the $100,000/$200,000 phase-out thresholds are inflation-indexed -- they're fixed dollar amounts through 2028. You must report the vehicle's VIN on your return to claim the deduction, and lenders issue Form 1098-VLI reporting the interest paid.

What Affects Your Results
State-Specific Inputs
Each state has unique rates, fee schedules, and regulatory requirements that can affect results. This page's methodology and source card identify which inputs are sourced, modeled, or user-adjustable.
Income Level
Many calculations are income-dependent due to progressive tax brackets, phase-outs, or income-based eligibility thresholds. Higher income doesn't always mean proportionally higher costs.
Local Variations
State averages may not reflect your specific city or county. Local taxes, fees, and market conditions can vary ±20% from state averages.
Annual Changes
Tax rates, fee schedules, and regulations change. Check the recorded source-review date and verify critical numbers with the relevant agency.
Tips & Best Practices
- Always verify pre-filled values against your actual data. State averages are a good starting point but your situation may differ significantly.
- Run multiple scenarios by adjusting key inputs to see how changes affect your results. This helps with planning and decision-making.
- Compare your results across states using the related calculators linked below — especially valuable if you're considering relocating or doing business in another state.

Our editorial standardsFrequently Asked Questions
How much car loan interest can I deduct?
Up to $10,000 per year for tax years 2025 through 2028, per 26 U.S.C. Section 163(h)(4). The deduction is reduced by $200 for every $1,000 (rounding any partial $1,000 up) your MAGI exceeds $100,000 ($200,000 if married filing jointly), reaching zero at $150,000 MAGI (single) or $250,000 MAGI (joint).
Does the vehicle have to be new?
Yes. The vehicle's "original use" must commence with you -- a used vehicle, even one new to you, does not qualify. It must also be assembled in its final form in the United States, have a gross vehicle weight rating under 14,000 lbs, and be a car, minivan, van, SUV, pickup truck, or motorcycle with at least 2 wheels.
Does leasing a car qualify for this deduction?
No. Only interest on a loan used to purchase a qualifying vehicle counts -- lease payments are explicitly excluded under 26 U.S.C. Section 163(h)(4)(B)(ii), no matter how the lease is structured.
Do I need to file jointly with my spouse to claim this deduction?
No -- this is a key difference from the tips, overtime, and senior deductions in this same OBBBA package. Section 163(h)(4) has no joint-filing requirement, so Married Filing Separately taxpayers can still claim it, using the same $100,000 MAGI phase-out threshold as single filers (not a reduced amount).
What if the vehicle is used partly for business?
You must expect the vehicle to be used for personal purposes more than 50% of the time. If you use it mostly for business, delivery, rideshare driving, or another trade or business, it does not qualify as being "for personal use" under the statute, even if you also drive it personally sometimes.
