How This Calculator Works
This tool estimates your federal tax savings under the auto loan interest deduction created by the One Big Beautiful Bill Act (OBBBA), effective for tax years 2025 through 2028. It also estimates your total monthly cost of ownership and compares it to an equivalent gas car.
Monthly Loan Payment
Standard amortization formula:
Deduction Calculation
The deduction equals the lesser of (a) actual interest paid on the loan during the tax year, or (b) $10,000. The deduction applies only to the first 48 months of the loan and only to interest on a new, US-assembled vehicle acquired after Dec 31, 2024.
Income Phase-Out
The deduction is fully phased out at $150,000 (Single/HOH) or $250,000 (MFJ). Married Filing Separately does not qualify.
Note: The exact rounding method for the phase-out ($200 per full $1,000 vs. per fraction thereof) may be clarified in final IRS regulations. Consult a tax professional for your specific situation.
Tax Savings
Tax savings = final deduction × your estimated federal marginal tax rate. This is an estimate — your actual benefit depends on your complete tax situation, other deductions, credits, and state taxes. Tax savings shown are based on 2025 federal marginal brackets as an approximation; current-year brackets may differ.
Total Cost of Ownership
- Loan payment — calculated from your inputs
- Insurance — state-level estimate (national average adjusted by state)
- Charging — annual miles ÷ EV efficiency × electricity rate
- Gas car fuel — annual miles ÷ MPG × gas price
- Gas car insurance — estimated at ~18% lower than EV insurance
Data Sources
- Deduction rules — Federal Register / IRS guidance on OBBBA §70203
- Tax brackets — IRS published marginal rates (2025, used as approximation)
- US assembly — NHTSA VIN Decoder reference (verify every vehicle)
- State incentives — DOE Alternative Fuels Data Center (verify current status)
- Electricity & gas prices — U.S. Energy Information Administration (EIA)
- Insurance — industry national averages, state-adjusted (estimate)
Limitations

Frequently Asked Questions
What is the EV loan interest deduction?
The OBBBA created a federal income tax deduction of up to $10,000 per year for interest paid on a loan used to purchase a new, US-assembled vehicle. It applies to tax years 2025 through 2028 and is available whether you itemize or take the standard deduction.
How much can I deduct?
Up to $10,000 per year in interest paid, subject to income phase-outs. The deduction applies only to interest paid during the first 48 months of the loan.
Does my EV qualify?
The vehicle must be new (not used), have final assembly in the United States, and be acquired after December 31, 2024. Verify US assembly with the NHTSA VIN Decoder at vpic.nhtsa.dot.gov.
What is the income limit?
The deduction phases out starting at $100,000 MAGI (Single/HOH) or $200,000 MAGI (MFJ). It is fully phased out at $150,000 (Single/HOH) or $250,000 (MFJ). Married Filing Separately does not qualify.
Can I claim it with the standard deduction?
Yes. This is an above-the-line deduction claimed on Schedule 1-A. You do not need to itemize.
Does a used EV qualify?
No. The vehicle must be new. Used vehicles do not qualify for this deduction (though a separate up-to-$4,000 used EV credit may apply under §25E — verify current status).
Does a lease qualify?
No. The deduction applies only to interest paid on a loan for a purchase. Leases are not eligible.
What if I'm married filing separately?
You do not qualify for the deduction if you file as Married Filing Separately.
How does the phase-out work?
For every $1,000 (or fraction thereof) that your MAGI exceeds the threshold ($100,000 Single/HOH or $200,000 MFJ), your deduction is reduced by $200. At $150,000 Single or $250,000 MFJ, the deduction is fully eliminated.
What form do I use?
The deduction is reported on Schedule 1-A (Form 1040) using the auto loan interest information reported by your lender.
How does this compare to the old $7,500 credit?
The $7,500 federal EV tax credit (§30D) ended for vehicles acquired after September 30, 2025. The new deduction is up to $10,000 per year for 4 years but is worth your marginal tax rate, not the full $10,000. For a buyer in the 22% bracket, a full $10,000 deduction is worth ~$2,200 per year — roughly $8,800 over four years, though actual interest paid is usually lower.
Is this tax advice?
No. This calculator provides estimates only. Consult a qualified tax professional about your specific situation.
EV Loan Interest Deduction Calculator: How to Calculate Your $10,000 Federal Tax Savings (2026–2028)
If you financed a new electric vehicle — or are about to — the One Big Beautiful Bill Act (OBBBA) created a federal income tax deduction of up to $10,000 per year for auto loan interest. The prior $7,500 federal EV tax credit ended for vehicles acquired after September 30, 2025, and this loan interest deduction is what replaced it for buyers who finance.
The challenge: eligibility depends on several overlapping rules — the vehicle must be new, must have had its final assembly in the United States, and your income determines how much you can actually deduct. This guide walks through every rule, shows the math, and helps you estimate your total monthly cost of ownership when you factor in the deduction alongside insurance and charging.
Use the calculator on this page to enter your specific loan and income details and get an estimate. Then read on to understand exactly how the numbers are derived and what can change them.
Key Takeaways
- Deduction cap: Up to $10,000 per year in qualified passenger vehicle loan interest (QPVLI), available for tax years 2025–2028. The cap is $10,000 per return, regardless of filing status.
- Vehicle requirements: The vehicle must be new (used vehicles do not qualify), purchased for personal use, and have had its final assembly in the United States. Leased vehicles also do not qualify.
- Income phase-out: The deduction phases out starting at $100,000 MAGI (Single/HOH) or $200,000 MAGI (MFJ), reduced by $200 per $1,000 above the threshold.
- Filing status: Married Filing Separately does not qualify for the deduction.
- Claimed above-the-line: You can claim this deduction whether you itemize or take the standard deduction. It is reported on Schedule 1-A.
- Interest only, not principal: The deduction applies only to the interest portion of your loan payments — not the entire payment or vehicle price.
How the EV Loan Interest Deduction Works
What Is the OBBBA Auto Loan Interest Deduction?
The OBBBA added a new provision to the Internal Revenue Code (Section 163(h)(4)) that allows taxpayers to deduct qualified passenger vehicle loan interest for taxable years beginning after December 31, 2024, and before January 1, 2029.
In plain terms: if you take out a loan to buy a new, US-assembled car or light truck for personal use, the interest you pay on that loan during the tax year can be deducted from your taxable income — up to $10,000 per year.
This is an above-the-line deduction, meaning you claim it regardless of whether you itemize. It is available to individuals, decedents' estates, and non-grantor trusts.
How Much Can You Deduct?
The maximum deduction is $10,000 per taxable year, per return — regardless of filing status. However, three factors typically reduce the actual amount:
- Actual interest paid: Most car buyers pay less than $10,000 in interest per year, so the deduction equals actual interest paid.
- Income phase-out: Starting at $100,000 MAGI (Single) or $200,000 MAGI (MFJ), the deduction is reduced by $200 for every $1,000 your income exceeds the threshold.
- 48-month interest window: The deduction applies only to interest paid during the first 48 months of the loan.
Eligibility Requirements
New Vehicle Requirement
The vehicle must be brand new — its original use must begin with you as the taxpayer. Used vehicles and certified pre-owned vehicles do not qualify. Leased vehicles also do not qualify; the loan must be a purchase financing loan.
US Assembly Requirement
The vehicle's final assembly must have occurred in the United States. The IRS final regulations clarify the rules for determining whether final assembly occurred domestically. The most practical way to verify is to check the first character of the Vehicle Identification Number (VIN). A VIN starting with 1, 4, or 5 indicates the vehicle was assembled in the United States.
You can verify any specific vehicle using the National Highway Traffic Safety Administration (NHTSA) VIN Decoder at vpic.nhtsa.dot.gov.

Assembly locations are based on available information and may change by model year. Always verify the specific vehicle's VIN before purchase.
Income Limits (MAGI Phase-Out)
The deduction phases out for higher-income taxpayers. The phase-out thresholds are based on Modified Adjusted Gross Income (MAGI):
| Filing Status | Full Deduction Below | Fully Phased Out Above | Reduction Rate |
|---|---|---|---|
| Single | $100,000 | $150,000 | $200 per $1,000 over threshold |
| Head of Household | $100,000 | $150,000 | $200 per $1,000 over threshold |
| Married Filing Jointly | $200,000 | $250,000 | $200 per $1,000 over threshold |
| Married Filing Separately | Does not qualify | ||
Filing Status Restrictions
Taxpayers filing as Married Filing Separately (MFS) are not eligible for this deduction. All other filing statuses — Single, Head of Household, and Married Filing Jointly — can qualify if they meet the vehicle and income requirements.
How the Deduction Is Calculated (Step by Step)
The calculation follows a specific sequence:
- Calculate annual interest paid. Generate an amortization schedule for your loan. Sum the interest portion of each monthly payment for the tax year. Interest is front-loaded — Year 1 interest is higher than Year 2, and so on.
- Apply the $10,000 cap. If your annual interest exceeds $10,000, cap the deductible amount at $10,000.
- Apply the income phase-out. If your MAGI exceeds the threshold for your filing status, reduce the deduction. The reduction is calculated as: Phase-out = (MAGI − Threshold) ÷ $1,000 × $200.
- Calculate tax savings. Multiply the final deduction by your federal marginal tax rate to estimate your actual tax savings.
Example Calculation
Scenario: $45,000 EV, $5,000 down payment, $40,000 loan at 7% APR for 60 months, Single filer with $75,000 MAGI, purchased in California.
| Metric | Value |
|---|---|
| Loan amount | $40,000 |
| Monthly payment | ~$792 |
| Year 1 interest paid | ~$2,688 |
| Deductible (under $10K cap) | ~$2,688 |
| Income phase-out | $0 (MAGI below $100K) |
| Estimated tax savings (22% bracket) | ~$591 in Year 1 |
| 4-year total deduction | ~$7,952 |
| 4-year total tax savings | ~$1,750 |
Tax savings are estimates based on 2025 marginal brackets. Your actual benefit depends on your complete tax situation. Monthly payment and interest calculations use standard amortization.
Use the EV Loan Interest Deduction Calculator above to run your own numbers with your specific loan amount, APR, income, state, and EV model.
Federal Deduction + State EV Incentives
The federal deduction is not the only incentive available in 2026. Several states offer their own EV rebates or tax credits that can significantly reduce your purchase cost — and in some cases, you can stack them with the federal deduction.
California
California now offers $3,500 off at the dealership for first-time zero-emission vehicle buyers, and $1,750 off used EVs sold for up to $25,000. This program is funded through the 2026–27 state budget. Income eligibility requirements apply.
Colorado
Colorado's state EV tax credit was $3,500 for vehicles purchased in 2025, but dropped to $750 for the 2026 tax year. It is scheduled to further reduce in future years. Verify the current amount before purchase.
New Jersey
New Jersey offers a point-of-sale rebate of up to $4,000 through the Charge Up New Jersey program, plus a sales tax exemption on qualifying EVs. The amount is now tied more closely to the vehicle's list price.
Other States
Many other states — including Massachusetts, New York, Oregon, and Connecticut — offer their own EV rebates or point-of-sale incentives. The U.S. Department of Energy's Alternative Fuels Data Center (AFDC) at afdc.energy.gov/laws/search maintains a comprehensive, searchable database by state and incentive type.
Important: State programs are funding-limited and can change without notice. Always verify current eligibility, amounts, and application windows directly with the state agency before relying on a specific incentive.
Old $7,500 Tax Credit vs. New $10,000 Deduction
The $7,500 federal EV tax credit (Section 30D) ended for vehicles acquired after September 30, 2025. The loan interest deduction is what replaced it — but the two work very differently.
| Feature | Old $7,500 EV Credit (30D) | New $10,000 Deduction (OBBBA) |
|---|---|---|
| Type | Tax credit (dollar-for-dollar reduction) | Above-the-line tax deduction |
| Maximum value | $7,500 (full value if tax liability ≥ $7,500) | $10,000 deduction × your marginal tax rate |
| Approximate value at 22% bracket | $7,500 | ~$2,200/year (if full $10,000 interest paid) |
| Duration | One-time at purchase | Annual for up to 4 years |
| Vehicle requirement | New EV meeting specific criteria | New, US-assembled vehicle (any fuel type) |
| Income limits | Yes (AGI-based) | Yes (MAGI-based phase-out) |
| Status | Expired Sept 30, 2025 | Active 2025–2028 |
The key difference: the old credit was a direct dollar-for-dollar reduction of your tax bill. The new deduction reduces your taxable income, so its actual value depends on your marginal tax rate. A buyer in the 22% bracket who pays $10,000 in interest would save approximately $2,200 per year — about $8,800 over four years, which can exceed the old credit's one-time $7,500 if they finance a sufficiently large amount. But if you pay less interest, or your income phases you out, the total benefit shrinks.
Total Cost of Ownership: What the Deduction Means for Your Monthly Budget
The deduction is one piece of the puzzle. To get a realistic picture of what an EV costs you monthly, you need to factor in the loan payment, insurance, and charging costs together.
Monthly Payment Breakdown
Your loan payment depends on the amount financed, APR, and term. Average new car loan rates were 6.35% in Q2 2026, with super-prime borrowers (credit scores 781+) averaging 4.41% and deep subprime borrowers (300–500) averaging 16.11%. Manufacturer promotional rates can be significantly lower — the 2027 Chevy Bolt, for example, is offered with financing as low as 0.9% APR for 36 months or 2.9% for 60 months.
Insurance Costs
EV insurance premiums vary significantly by state, model, and driver profile. As a general planning estimate, EV insurance tends to run higher than comparable gas vehicle coverage — often by 15–25% nationally. For accurate state-level estimates, consult your insurance provider or use a comparison tool before purchase.
Charging Costs
Home charging cost depends on your electricity rate and your vehicle's efficiency. A typical calculation:
Annual charging cost = (Annual miles ÷ EV efficiency in mi/kWh) × Electricity rate ($/kWh)
For example, 12,000 miles ÷ 3.5 mi/kWh × $0.15/kWh = approximately $514 per year, or about $43 per month. Public DC fast charging costs significantly more per kWh and can double or triple this figure.
Total Monthly Cost vs. Gas Car
When you combine loan payment + insurance + charging (or fuel), an EV's total monthly cost is often competitive with a comparable gas car — particularly when the loan interest deduction is applied. But this depends heavily on your specific electricity rate, insurance premium, and the gas car you're comparing against.
The calculator on this page estimates all three cost components side by side so you can see the full picture.

Methodology & Data Sources
Calculation Formulas
Monthly loan payment (amortization):
M = P × [r(1+r)n] ÷ [(1+r)n − 1]
Where P = loan amount (vehicle price − down payment − trade-in), r = monthly interest rate (APR ÷ 12 ÷ 100), and n = loan term in months.
Deduction: min(annual interest paid, $10,000) minus phase-out reduction.
Phase-out reduction: (MAGI − threshold) ÷ $1,000 × $200, capped at zero (cannot be negative).
Tax savings: final deduction × estimated marginal tax rate.

Frequently Asked Questions
Does a used EV qualify for the loan interest deduction?
No. The vehicle must be new — its original use must begin with you as the taxpayer. Used vehicles and certified pre-owned vehicles do not qualify. A separate used EV tax credit (Section 25E) may apply in some cases, but it also ended for vehicles acquired after September 30, 2025. Verify current status with the IRS or a tax professional.
Can I claim the deduction if I leased my EV?
No. Leased vehicles do not qualify. The deduction applies only to interest paid on a loan for a purchase.
What form do I use to claim the EV loan interest deduction?
The deduction is reported on Schedule 1-A (Form 1040). Your lender is required to report the interest you paid on a specified passenger vehicle loan if it aggregates $600 or more for the calendar year.
How does the phase-out work exactly?
For every $1,000 (or fraction thereof) that your MAGI exceeds the threshold, the deduction is reduced by $200. For example, if you're a Single filer with $105,000 MAGI, you're $5,000 over the $100,000 threshold — a reduction of $1,000. If your deductible interest was $3,500, it would be reduced to $2,500.
Is the deduction available if I take the standard deduction?
Yes. This is an above-the-line deduction, meaning you can claim it whether you itemize or take the standard deduction. It is available to individuals, decedents' estates, and non-grantor trusts.
Does the vehicle have to be electric?
No. The deduction applies to any new, US-assembled passenger vehicle purchased for personal use — including gasoline, hybrid, and electric vehicles. However, the EV context is particularly relevant because the prior $7,500 EV tax credit expired and this deduction is the primary federal incentive replacement for EV buyers who finance.
What if I'm married filing separately?
Married Filing Separately taxpayers do not qualify for the deduction. Only Single, Head of Household, and Married Filing Jointly filers can claim it.
How do I know if my EV was assembled in the United States?
Check the first character of your VIN. A VIN beginning with 1, 4, or 5 indicates US assembly. You can verify any specific VIN using the NHTSA VIN Decoder at vpic.nhtsa.dot.gov. Dealership documentation should also confirm the final assembly location.
Can I combine the federal deduction with state EV incentives?
Yes, in many cases you can. State rebates and the federal deduction operate independently — the federal deduction reduces your taxable income, while state programs typically provide direct rebates or point-of-sale discounts. Check your state's specific program rules for any stacking restrictions.
What happens if I sell the vehicle before the loan is paid off?
The deduction applies to interest you paid during the tax year while the loan was active. If you sell the vehicle and pay off the loan, you can still deduct interest paid during that tax year, up to the applicable limits.
