For nearly 40 years, personal car loan interest has been completely off-limits as a federal tax deduction. The One Big Beautiful Bill Act changed that — but the new break comes with enough conditions that it helps a narrower slice of freelancers than the headlines suggest.
What the deduction actually offers
Starting with the 2025 tax year and running through 2028, eligible taxpayers can deduct up to $10,000 per year of interest paid on a loan used to buy a new, personal-use vehicle — a car, SUV, minivan, van, pickup truck, or motorcycle under 14,000 pounds gross vehicle weight. It's an above-the-line deduction, meaning you can claim it whether you itemize or take the standard deduction, reported on a new Schedule 1A.
The requirements that trip people up
The vehicle must be new (you're the first owner), must undergo final assembly in the United States, and the loan must have originated after December 31, 2024, secured by a first lien on the vehicle itself — not a lease, a HELOC, or another line of credit. Used vehicles and leased vehicles are explicitly excluded entirely, regardless of where they were assembled.
Why 'personal-use' is the catch for freelancers
This deduction is specifically for a personal-use vehicle, determined by a more-than-50%-personal-use test at the time the loan is signed. A freelancer who finances a vehicle used mostly for business generally doesn't qualify for this particular deduction on that vehicle — though the business-use portion of the same loan's interest may already be deductible separately as an ordinary business expense on Schedule C, under the existing rules that predate OBBBA.
Splitting interest for a mixed-use vehicle
If you use the vehicle for both personal driving and self-employed business trips, you generally allocate the loan interest by your actual business-use percentage: the business-use share is deducted as a Schedule C expense (unaffected by this deduction's income limits), while the personal-use share may qualify for the new $10,000 deduction, subject to its own income phase-out described below.
The income phase-out
The deduction phases out for taxpayers with modified adjusted gross income above $100,000 (single, head of household, or married filing separately) or $200,000 (married filing jointly), reduced by $200 for every $1,000 (or part of $1,000) of MAGI above the threshold. Because the reduction is a flat dollar amount rather than scaled precisely to the interest paid, the deduction can shrink to zero before income reaches the level that would mathematically zero out the full $10,000 cap.
Frequently asked questions
How do I know if a vehicle was assembled in the United States?
Check the vehicle's information label or decode its VIN — the same VIN you'll need to report on your return each year you claim the deduction. Assembly location can vary by trim level or model year for the same nameplate, so confirm the specific vehicle you're financing, not just the model name.
Does this deduction replace the standard mileage rate or actual vehicle expense deduction for my business?
No — this is a separate, personal-use deduction. Business-use vehicle expenses, including a business-use share of loan interest, continue to follow the existing standard mileage rate or actual expense rules on Schedule C.
Is this deduction permanent?
No — it's currently scheduled to apply only for tax years 2025 through 2028, and IRS guidance on some details was still proposed rather than final as of when this guide was last updated.
