To claim the no tax on car loan interest deduction, get an interest statement from your lender (Form 1098-VLI or an equivalent monthly or annual statement), confirm your vehicle and loan meet the qualification rules, then report the eligible interest on the new Schedule 1-A (Form 1040), which carries the deduction to line 13b of your 1040 and reduces your adjusted gross income.1Internal Revenue Service. Schedule 1-A, Additional Deductions – What to Know About the New Form The deduction is capped at $10,000 of interest per year, phases out at higher incomes, and is available whether you itemize or take the standard deduction.2Internal Revenue Service. Topic No. 505, Interest Expense
Confirm Your Vehicle and Loan Qualify
Before you put a number on the return, run through the five requirements. Miss one and the interest is not qualified, even if your lender sent you a statement.3Internal Revenue Service. One, Big, Beautiful Bill Act – Tax Deductions for Working Americans and Seniors
- The vehicle must be brand new. Your original use has to be the first use. Used, certified pre-owned, and end-of-lease buyouts do not qualify.
- Final assembly must occur in the United States. The dealer’s window sticker shows this, and you can cross-check the plant-of-manufacture digit in the VIN through the NHTSA VIN decoder.
- You must have intended more than 50% personal use at the time you took out the loan. It is a one-time test at purchase, not something you recompute each year.
- The loan must be secured by a first lien on the vehicle. Leases do not count.
- The loan must have originated after December 31, 2024. A loan taken out in 2024 or earlier is disqualified, and refinancing it after the cutoff will not fix that.
Cars, minivans, vans, SUVs, pickups, and motorcycles all qualify as long as they have a gross vehicle weight rating under 14,000 pounds and are built primarily for public roads.4Office of the Law Revision Counsel. 26 USC 163 – Interest Salvage-title vehicles, parts or scrap purchases, fleet buys, and purely commercial vehicles are out.
If you refinanced a qualifying loan, you can keep deducting the interest so long as the new loan is still a first lien on the same vehicle and the new principal does not exceed the outstanding balance on the original loan at the time of refinancing. Cash-out amounts above that balance are not eligible.
Figure Out How Much You Can Deduct
The deduction is capped at $10,000 of qualifying interest per year. On top of that, it phases out based on income. You get the full amount only if your modified adjusted gross income stays under $100,000 (single) or $200,000 (joint). Above those thresholds, the deduction drops by $200 for every $1,000 of additional MAGI, reaching zero at $150,000 single and $250,000 joint.4Office of the Law Revision Counsel. 26 USC 163 – Interest
Here is how the math plays out. A single filer with $120,000 in MAGI is $20,000 over the threshold. Twenty times $200 is a $4,000 reduction, leaving a maximum $6,000 deduction that year. For most people filing a purely domestic return, MAGI equals AGI; the only add-backs are foreign earned income and possessions income exclusions.
The Filing Steps
Get Your Interest Statement
Lenders that collect $600 or more of interest on a qualifying loan are required to report it on the new Form 1098-VLI (Vehicle Loan Interest Statement). Box 1 shows the total interest received during the year. For the 2025 tax year, the IRS is allowing lenders to satisfy the reporting requirement through an online portal, monthly statements, or an annual statement in place of the 1098-VLI itself.5Internal Revenue Service. Instructions for Form 1098-VLI If nothing has arrived by tax time, call your lender.
The number your lender reports is the starting point, not the finished deduction. The $10,000 cap and the income phase-out both apply after that.6Internal Revenue Service. Form 1098-VLI Vehicle Loan Interest Statement
Complete Schedule 1-A
Schedule 1-A (Form 1040) is where the calculation happens. Part I works out your MAGI so the phase-out can be applied. The vehicle loan interest section asks for total interest paid, any portion already claimed as a business expense elsewhere on your return, and the net amount eligible for this deduction.1Internal Revenue Service. Schedule 1-A, Additional Deductions – What to Know About the New Form The result flows to line 13b of Form 1040 as an adjustment to income, so it lowers AGI directly. That in turn can improve outcomes on other AGI-sensitive calculations on your return.
Include the VIN
Your vehicle identification number has to appear on the return for the year you claim the deduction. The statute treats missing-VIN interest as not qualified, and the IRS will disallow the deduction on review if it is left off.4Office of the Law Revision Counsel. 26 USC 163 – Interest
If You’re Self-Employed, Split the Interest
Self-employed filers who use the car for both business and personal driving can claim interest in two places on the same return. The business-use portion goes on Schedule C as an interest expense; the personal-use portion goes on Schedule 1-A under the new provision.7Internal Revenue Service. Instructions for Schedule C (Form 1040) The 2025 Schedule C instructions call out this split explicitly.
The allocation runs on your business-use percentage. Paid $2,000 in interest and drove the car 60% for business? Then $1,200 goes on Schedule C, and the remaining $800 is eligible for Schedule 1-A (still subject to the $10,000 cap and the income phase-out). Schedule F filers follow the same logic with the business portion on Schedule F.8Internal Revenue Service. Instructions for Schedule F (Form 1040)
Load the business side first when you have the choice. Interest on Schedule C reduces net self-employment income, which lowers self-employment tax as well as income tax. The 2026 self-employment tax rate is 15.3% on net earnings, made up of 12.4% Social Security (on income up to $184,500) and 2.9% Medicare on all earnings.9Social Security Administration. Contribution and Benefit Base A dollar shifted to Schedule C saves more than the same dollar on Schedule 1-A, which only touches income tax.
One caveat on method choice: under the actual expense method, business-use loan interest is reported as a separate interest line on Schedule C rather than being folded into vehicle operating costs.10Internal Revenue Service. Topic No. 510, Business Use of Car Under the 2026 standard mileage rate of 72.5 cents per mile, the IRS does not explicitly address loan interest, so check current guidance or a tax professional before claiming interest alongside the per-mile rate.
Records to Keep
The deduction only survives an audit if you can back it up. Hold on to:
- Your Form 1098-VLI or equivalent lender statement showing interest paid.
- The original loan agreement showing origination date, first-lien status, and the vehicle.
- Proof of U.S. final assembly: the window sticker, vehicle information label, or a screenshot from the NHTSA VIN decoder.
- The bill of sale or purchase agreement showing the vehicle was new.
If you’re also splitting interest onto Schedule C, keep a contemporaneous mileage log with date, start and end points, business purpose, and miles for each trip, plus your odometer readings at the start and end of the year.10Internal Revenue Service. Topic No. 510, Business Use of Car Entries need to be made at or near the time of travel, not reconstructed in April.
Keep everything for at least three years from the filing date, the standard IRS assessment window.11Internal Revenue Service. How Long Should I Keep Records If you underreport income by more than 25%, the window stretches to six years.
Deadlines and Expiration
The deduction applies only for tax years 2025 through 2028.4Office of the Law Revision Counsel. 26 USC 163 – Interest Unless Congress extends it, interest paid in 2029 and later reverts to non-deductible personal interest. Your loan can run longer than that; only the interest accruing inside the four-year window qualifies. And the loan origination date is a hard line: loans dated on or before December 31, 2024, are out, and refinancing after that date will not rescue them because the original indebtedness predates the cutoff.
Situations Where the Deduction Does Not Apply
W-2 employees who drive a personal car for work cannot deduct the business-use portion of the loan interest on a federal return. The Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee expenses starting in 2018, and the new law did not restore it. The personal-use deduction on Schedule 1-A is still available regardless of employment status.2Internal Revenue Service. Topic No. 505, Interest Expense Statutory employees are the exception: if the “Statutory employee” box is checked on your W-2, you can file Schedule C and split the interest the same way a self-employed filer does.12Internal Revenue Service. Statutory Employees
Claiming interest you do not qualify for carries the ordinary accuracy-related penalty of 20% of the resulting underpayment for negligence or substantial understatement.13Internal Revenue Service. Accuracy-Related Penalty If the IRS finds the claim was fraudulent, the civil fraud penalty is 75% of the underpayment.14Internal Revenue Service. Avoiding Penalties and the Tax Gap The common trip-ups are inflating a business-use percentage or claiming interest on a vehicle that fails the new-vehicle or American-assembly test.
