Car Loan Interest Deduction Calculator
As of April 1, 2026, the old $7,500 new EV credit and $4,000 used EV credit are gone for vehicles acquired after September 30, 2025. The main federal replacement for households is a temporary deduction of up to $10,000 of qualifying car-loan interest per year on a new vehicle that meets the federal rules.

This is not another EV credit calculator. It is a reality check on the replacement rule that now matters most for many buyers: whether your car-loan interest is deductible under the post-September 30, 2025 framework.
The deduction is helpful, but it is narrower than the old EV credit. It depends on the loan, your income, and the vehicle facts. It is a deduction, not a dollar-for-dollar credit.
The old EV credits are gone. This calculator estimates the temporary replacement deduction for qualifying new-vehicle loan interest and can optionally use your VIN to check the U.S. final-assembly rule.
It focuses on the federal car-loan interest deduction, not on dealer credits, lease incentives, or state rebates. You enter the interest paid for the year, your income, and the key qualification facts, then refine the estimate with a VIN lookup if you have one.
How PRIA Approached This
This calculator was written by Jon Ragsdale and reviewed by David Duley. PRIA treats tools like this as household policy-risk explainers, not generic widgets. We separate current law from proposals when relevant, translate public rules into plain English, and present the output as an educational estimate rather than personalized advice.

Frequently Asked Questions
- Is car loan interest deductible in 2026?
- Sometimes. For tax years 2025 through 2028, individuals can deduct up to $10,000 per year of qualified passenger vehicle loan interest if the loan and vehicle meet the federal rules. The vehicle must be new, for personal use, and have final assembly in the United States.
- Does this replace the old EV tax credit?
- For many households, yes. The old new and used EV credits ended for vehicles acquired after September 30, 2025. The replacement is not another credit. It is an above-the-line deduction for qualifying vehicle-loan interest on an eligible new vehicle.
- Is the car loan interest deduction a tax credit?
- No. Many people search for a car loan tax credit, but the current federal benefit is a deduction, not a credit. That means it reduces taxable income rather than reducing your tax bill dollar for dollar. One of the core rules is that the vehicle must have final assembly in the United States.
- How does the income phaseout work?
- The deduction begins phasing out once modified adjusted gross income goes above $100,000 for most filers or $200,000 for married couples filing jointly. The reduction is $200 for each $1,000 above the threshold, using the IRS worksheet rounding rule that rounds the excess up to the next whole thousand.
- Do used vehicles qualify?
- No. The vehicle’s original use must begin with the taxpayer. Used vehicles do not qualify for the car-loan interest deduction, even though a separate used EV credit existed before September 30, 2025.
- Do lease payments qualify?
- No. Lease payments are not qualified passenger vehicle loan interest. The deduction applies to interest on a qualifying loan, not to lease payments.
- Do I have to itemize to claim it?
- No. The deduction is available to both itemizing and non-itemizing taxpayers. It is claimed on Schedule 1-A rather than as part of Schedule A itemized deductions.
- Can I deduct more than $10,000 if I have multiple loans?
- No. The annual cap is $10,000 per return. Even if you have more than one qualifying vehicle loan, the total deduction is capped at $10,000 for the year before the MAGI phaseout is applied.
- What if part of the interest was already deducted for business use?
- You cannot deduct the same interest twice. If part of the interest was already deducted on Schedule C, Schedule E, or Schedule F, only the remaining eligible amount can be claimed on Schedule 1-A.
- What else can disqualify the deduction besides income?
- The loan generally must be secured by the vehicle, the vehicle must be new and for personal use, final assembly must be in the United States, and the gross vehicle weight rating must stay under 14,000 pounds. This calculator asks about those higher-signal qualification issues, but it is still an educational estimate rather than a document review.
The EV credit is gone, but a new vehicle-loan deduction took its place. See whether your purchase qualifies before you count on the tax break.

If your loan qualifies, you may be able to deduct up to $10,000 of interest per year for tax years 2025 through 2028. But the deduction begins to phase out above $100,000 of MAGI for most filers and above $200,000 for married couples filing jointly.
Since year-end 2025, the IRS and Treasury have added more detail to how this rule works in practice. That includes IRS Notice 2025-57 for transitional reporting guidance and a January 2, 2026 proposed Treasury/IRS rule that spells out definitions around qualifying loans, vehicle use, liens, VIN reporting, and other edge cases.
Made in America Car Loan Tax Credit: What People Usually Mean
Many people are searching for a “Made in America Trump car loan tax credit,” but the current federal benefit is more limited than that phrase suggests. It is not a dollar-for-dollar credit. It is a temporary deduction for qualifying passenger-vehicle loan interest, and one of the key rules is that the vehicle must have final assembly in the United States.
That is why the VIN step matters. If you have the VIN, this updated calculator can now help you check the final-assembly question instead of making you guess.
Why This Is Smaller Than The Old EV Credit
The old EV credit reduced your tax bill directly. This rule only lets you deduct qualifying interest from income. That usually means the cash value is far smaller than the old $7,500 headline amount unless you are paying a lot of interest and remain below the phaseout threshold.
Who This Calculator Helps Most
- Households deciding between buying and leasing a new vehicle.
- Buyers comparing a qualifying U.S.-assembled vehicle with a nonqualifying one.
- Filers close to the MAGI phaseout who need a quick planning estimate.
- People who keep hearing that there is still an “EV tax break” and want to know what that really means now.
What This Calculator Does Not Do
It now helps with VIN-based final-assembly checking, but it still does not determine every tax fact by itself. It does not confirm whether the vehicle is new to you, whether the VIN will be reported correctly on the return, or what state rebates, dealer lease cash, or charging economics may apply.
It also cannot verify lender-side reporting or every document-level fact from your deal jacket. The loan generally must be secured by the vehicle, and the vehicle must stay under the 14,000-pound GVWR limit. Most ordinary passenger vehicles fit those rules, but some edge cases do not.
