Taxpayers who purchased a new vehicle in 2025 can look forward to a new tax deduction on their next tax return. This new tax benefit allows taxpayers who bought and financed a qualifying vehicle after December 31, 2024, to deduct up to $10,000 of car loan interest from their taxable income.
This new car loan deduction is effective through 2028.
Does the Deduction Apply to Any Financed Vehicle?
No, only new vehicles that meet certain criteria qualify for the tax deduction. Used vehicle loans are not eligible. Qualifying new vehicles must:
- Be a qualified passenger vehicle (car, minivan, van, SUV, pickup truck, or motorcycle)
- Have a gross vehicle weight rating of less than 14,000 pounds
- Be purchased for personal use, not business
- Undergo final assembly in the U.S.
To verify a vehicle’s final assembly, use the National Highway Traffic Safety Administration (NHTSA) VIN Decoder. All you need is the vehicle label at the dealership and the vehicle identification number (VIN).
Who Qualifies for the Car Loan Interest Deduction?
Not all taxpayers are income-eligible for the full auto loan deduction. Filers must have a modified adjusted gross income (MAGI) of less than:
- $100,000 for single tax filers
- $200,000 for joint filers
Keep in mind that your MAGI is what’s left after certain deductions, like student loan interest and eligible retirement contributions. This means even high earners may still be eligible for the deduction.
The Internal Revenue Service (IRS) also phases out the deduction gradually—so even if you exceed the income limits above, you may still be able to deduct some of your auto loan interest. For every $1,000 above the MAGI limit, the deduction shrinks by $200. For example, a single filer with a MAGI of $120,000 would see their allowable deduction reduced by $4,000.
The deduction is available regardless of whether you itemize or use the standard deduction.
Are There Any Other New Tax Breaks This Year?
The Trump Administration’s Big Beautiful Bill introduced other tax savings as well. Other changes, in addition to the auto loan interest deduction, boosted take-home pay for some filers and simplified how certain types of income are taxed.
Other notable updates taxpayers can benefits from in the 2025 and 2026 tax years include:
- Increased the standard deduction to $15,750 for singles and $31,500 for married couples (effective for tax year 2026)
- New senior deduction of $6,000 for single filers or $12,000 for married couples who are 65+ (effective for tax year 2026)
- No federal income tax on tips, up to $25,000 for single filers
- No federal income tax on overtime pay, up to $12,500 for single filers
- Boosted the child tax credit to $2,500
- Added a $1,000 government‑funded deposit into a tax‑advantaged account for eligible children born January 1, 2025 — December 31, 2028
On the flip side, some clean‑energy credits were eliminated or phased out. Credits for electric vehicles are no longer available for vehicles purchased after September 30, 2025. Tax year 2025 was the last year homeowners could receive a 30% tax credit for rooftop solar, geothermal heat pumps, or battery storage.
Like Everything Else, Tax Rules Are Always Evolving
The auto loan interest deduction and other changes give many taxpayers new ways to lower their tax bill in 2025 and beyond. As always, staying aware of which rules apply in which tax year can help you make the most of every new credit and deduction available. It also doesn’t hurt to have a good tax professional on your side to help maximize your savings.
