How the Calculation Works
The calculator applies the verified federal QPVLI rules. No estimates are fabricated — the formulas below match IRS guidance and the statute.
Step 1 — Eligibility (USA final assembly):
If assembly country = United States → eligible
If annual interest = $0 → not eligible (nothing to deduct)
Otherwise → eligible (subject to income phase-out)
Step 2 — $10,000 interest cap:
Capped Interest = min(Annual Interest, $10,000)
Step 3 — Income phase-out:
Threshold = $100,000 (Single, HOH, MFS) or $200,000 (MFJ)
If MAGI ≤ Threshold → Reduction = $0
If MAGI > Threshold → Reduction = floor((MAGI − Threshold) ÷ $1,000) × $200
Reduction capped at $10,000
Step 4 — Final deductible & savings:
Final Deductible = max($0, Capped Interest − Reduction)
Estimated Tax Savings = Final Deductible × Marginal Tax Rate
VIN Assembly Check
When you enter a VIN, the tool queries the official NHTSA vPIC decoder (a free US government API) to retrieve the vehicle's plant country. If the API is unavailable, the tool falls back to the ISO 3779 first-character rule used by the IRS and tax professionals:
| First Character | Assembly Region |
|---|---|
| 1, 4, 5 | United States |
| 70 – 7Z | United States |
| 2 | Canada |
| 3 | Mexico |
| J | Japan |
| K | South Korea |
| L | China |
| W | Germany |

How the $10,000 Car Loan Deduction Works (2025–2028)
The OBBBA QPVLI Deduction Explained
The Qualified Passenger Vehicle Loan Interest (QPVLI) deduction was created by the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. It allows individual taxpayers to deduct interest paid on a loan used to purchase a new qualified passenger vehicle for personal use, up to $10,000 per year.
The deduction applies to interest paid on loans incurred after December 31, 2024, for tax years beginning after December 31, 2024 and before January 1, 2029. In practical terms, this means tax years 2025, 2026, 2027, and 2028. The deduction is scheduled to expire after tax year 2028 under current law.
Unlike itemized deductions such as mortgage interest, QPVLI is an above-the-line deduction. This means you can claim it whether you take the standard deduction or itemize. It reduces your taxable income before the standard or itemized deduction is applied.
Key Eligibility Requirements
To qualify for the QPVLI deduction, your vehicle and loan must meet all of the following requirements:
| Requirement | Details |
|---|---|
| New vehicle only | The original use of the vehicle must begin with you. Used vehicles do not qualify. |
| USA final assembly | The vehicle's final assembly must have occurred in the United States. This is verified through the VIN. |
| Gross vehicle weight | The vehicle must have a gross vehicle weight rating (GVWR) of less than 14,000 pounds. Most sedans, SUVs, and pickup trucks fall below this limit. |
| Personal use | The vehicle must be used primarily for personal use (more than 50% of the time). Commercial vehicles and lease financing do not qualify. |
| First lien | The loan must be secured by a first lien on the vehicle. |
| Loan timing | The indebtedness must have been incurred after December 31, 2024. |
| VIN reporting | You must include the vehicle's VIN on your tax return (Schedule 1-A, Part IV). |
Eligible vehicle types include cars, minivans, vans, sport utility vehicles, pickup trucks, and motorcycles. The statutory definition excludes vehicles with final assembly outside the United States.
Check Your VIN: Is Your Car Assembled in the USA?
How VIN Decoding Works
Every vehicle has a 17-character Vehicle Identification Number (VIN). The first character of the VIN indicates the country or region where the vehicle was assembled. For vehicles assembled in the United States, the first character is typically 1, 4, or 5. Some VINs beginning with 7 (specifically 7F through 7Z and 70) also indicate US assembly, though these are less common.
The Internal Revenue Service has encouraged taxpayers to use the National Highway Traffic Safety Administration's (NHTSA) VIN decoder to confirm the final assembly location of their vehicle. The NHTSA vPIC decoder is a free public tool that returns the plant country from a VIN.
The final regulations clarify that taxpayers can determine the location of final assembly by either (1) the plant of manufacture as reported in the VIN, or (2) the final assembly point reported on the label affixed to the vehicle.
VIN First-Character Quick Reference
| First Character | Assembly Region | QPVLI Eligible? |
|---|---|---|
| 1, 4, 5 | United States | Yes |
| 70 – 7Z | United States | Yes (less common) |
| 2 | Canada | No |
| 3 | Mexico | No |
| J | Japan | No |
| K | South Korea | No |
| L | China | No |
| W | Germany | No |
Important note: The first-character rule is a quick reference, not a definitive eligibility determination. The statutory requirement is final assembly in the United States. Some vehicles assembled in the US may have VINs that do not follow the standard first-character convention. Always confirm with the NHTSA decoder or the vehicle's assembly label.
What to Do If Your Car Doesn't Qualify
If your VIN indicates assembly outside the United States, your vehicle does not qualify for the QPVLI deduction. This is a statutory requirement. You should not claim the deduction on your tax return. However, you may still be eligible for other deductions or credits. Consult a qualified tax professional about your specific situation.
Calculate Your Deduction After Income Phase-Outs
The $200 per $1,000 Reduction Formula
The QPVLI deduction is subject to an income-based phase-out. For every $1,000 (or portion thereof) that your Modified Adjusted Gross Income (MAGI) exceeds the threshold, your deduction is reduced by $200. The reduction cannot bring the deduction below zero.
The formula is:
Reduction = floor((MAGI − Threshold) / $1,000) × $200 Final Deductible = max($0, min(Annual Interest, $10,000) − Reduction)
The threshold is $100,000 for single filers, head of household, and married filing separately. For married filing jointly, the threshold is $200,000.
For the purposes of this phase-out, MAGI is defined as adjusted gross income plus any amount excluded from gross income under sections 911, 931, or 933 of the Internal Revenue Code.
Single vs Married Filing Jointly Thresholds
| Filing Status | Phase-Out Begins | Fully Phased Out |
|---|---|---|
| Single | $100,000 | $150,000 |
| Head of Household | $100,000 | $150,000 |
| Married Filing Separately | $100,000 | $150,000 |
| Married Filing Jointly | $200,000 | $250,000 |
The deduction is fully phased out when MAGI reaches $150,000 for single filers and $250,000 for joint filers.
Phase-Out Examples
Example 1: Single filer, MAGI $110,000
- MAGI exceeds threshold by $10,000
- Reduction = (10,000 / 1,000) × $200 = $2,000
- If annual interest was $3,500, capped at $10,000 = $3,500
- Final deductible = $3,500 − $2,000 = $1,500
Example 2: Married filing jointly, MAGI $225,000
- MAGI exceeds threshold by $25,000
- Reduction = (25,000 / 1,000) × $200 = $5,000
- If annual interest was $4,200, capped at $10,000 = $4,200
- Final deductible = $4,200 − $5,000 = $0 (reduced to zero)
Example 3: Single filer, MAGI $85,000
- MAGI below threshold of $100,000
- No reduction
- If annual interest was $3,200, final deductible = $3,200
What Your Tax Savings Look Like by Bracket
Deduction vs Credit: The Key Difference
A tax deduction reduces your taxable income. A tax credit reduces your tax owed dollar-for-dollar. The QPVLI deduction is a deduction, not a credit. This means the actual dollar savings depends on your marginal tax rate.
For example, a $3,200 deduction saves a taxpayer in the 22% bracket approximately $704 in federal income tax. The same deduction saves a taxpayer in the 32% bracket approximately $1,024. The deduction amount is the same; the savings depends on your bracket.
Savings at 12%, 22%, 24%, 32%, 35%
| Marginal Tax Rate | Savings on $3,200 Deduction | Savings on $10,000 Deduction |
|---|---|---|
| 12% | $384 | $1,200 |
| 22% | $704 | $2,200 |
| 24% | $768 | $2,400 |
| 32% | $1,024 | $3,200 |
| 35% | $1,120 | $3,500 |
| 37% | $1,184 | $3,700 |

Who Qualifies (and Who Doesn't)
New Vehicles Only
The original use of the vehicle must begin with you. The final regulations provide that original use generally commences with the first person who takes delivery of the vehicle after it is sold, registered, or titled. If you purchased a vehicle that was previously titled or registered to another person, it is a used vehicle and does not qualify.
Cars purchased at the end of a lease do not qualify. The purchase of a vehicle that was previously leased by someone else is a used vehicle purchase.
Lease Exclusion
Leased vehicles do not qualify for the QPVLI deduction. The deduction applies only to interest paid on a loan used to purchase a vehicle, not to lease payments. If you are leasing a vehicle, you cannot claim this deduction.
Personal Use Requirement
The vehicle must be purchased for personal use. The final regulations define personal use as use by the taxpayer, the taxpayer's spouse, or a related individual for more than 50% of the time the taxpayer expects to own the vehicle. Financing for commercial vehicles does not qualify.
Other Exclusions
- Vehicles with a gross vehicle weight rating of 14,000 pounds or more
- Vehicles with final assembly outside the United States
- Indebtedness not secured by a first lien on the vehicle
- Interest on loans for trailers, boats, or other non-passenger vehicles
How to Claim on Schedule 1-A
VIN Entry Requirements
To claim the QPVLI deduction, you must include your vehicle's VIN on Schedule 1-A (Form 1040), Additional Deductions, Part IV. The VIN is a 17-character identifier that allows the IRS to verify the vehicle meets the USA final assembly requirement.
The final regulations require taxpayers to include the VIN of the applicable passenger vehicle on the tax return. The deduction cannot be claimed without reporting the VIN.
Form 1098-VLI
Lenders that receive $600 or more in qualified passenger vehicle loan interest during a calendar year must file Form 1098-VLI, Vehicle Loan Interest Statement, with the IRS and furnish a statement to the borrower. The $600 threshold applies separately to each specified passenger vehicle loan.
Form 1098-VLI reports the total vehicle loan interest received during the year. This form helps taxpayers substantiate the interest paid when claiming the deduction. Not all lenders may have been required to file Form 1098-VLI for 2025 due to transitional relief; however, the reporting requirement is in effect for subsequent years.
Common Filing Mistakes
- Forgetting the VIN: The deduction cannot be claimed without reporting the VIN on Schedule 1-A. Double-check that the VIN is entered correctly.
- Claiming for a used vehicle: Only new vehicles qualify. If the vehicle was previously titled or registered, it does not qualify.
- Claiming for a lease: Lease payments are not loan interest and do not qualify.
- Exceeding the $10,000 cap: The maximum deduction is $10,000 per return per year, regardless of how much interest was actually paid.
- Ignoring the phase-out: If your MAGI exceeds the threshold, your deduction is reduced. Calculate the phase-out before claiming the full amount.
EV vs Gas: Does the Deduction Apply to Both?
Why QPVLI Is Not EV-Specific
The QPVLI deduction is not an electric vehicle deduction. It applies to any new qualified passenger vehicle with final assembly in the United States, whether that vehicle is powered by gasoline, diesel, hybrid, plug-in hybrid, or electricity.
A Tesla Model Y assembled in the United States qualifies. A Ford F-150 assembled in the United States qualifies. A Toyota Camry assembled in the United States qualifies. An imported EV does not qualify. An imported gas vehicle does not qualify.
The determining factor is final assembly location, not powertrain type.
What EV Buyers Need to Know After the Credit Expiration
The federal Clean Vehicle Credit (Section 30D) expired September 30, 2025, under the OBBBA. No new EV purchased after that date is eligible for the $7,500 credit. The QPVLI deduction was created as a separate provision and is not a replacement for the EV credit.
EV buyers who financed a new vehicle assembled in the United States may qualify for QPVLI. However, EV buyers should not assume eligibility based on the fact that their vehicle is electric. Eligibility depends entirely on final assembly location.
The Bipartisan Policy Center has reported that approximately 57% of the top 25 best-selling vehicles in the United States have final assembly in the country. This means a significant number of vehicles — both gas and electric — do not qualify.
What Happens After 2028
Under current law, the QPVLI deduction expires after tax year 2028. The statute applies to taxable years beginning after December 31, 2024 and before January 1, 2029. No extension has been enacted at the time of publication.
Taxpayers considering a vehicle purchase near the end of 2028 should be aware that interest paid in 2029 and later years would not be deductible under current law. Future legislation could change this, but no such legislation has been enacted.
Frequently Asked Questions
What is the car loan interest deduction?
The Qualified Passenger Vehicle Loan Interest (QPVLI) deduction is a federal tax deduction that allows eligible taxpayers to deduct up to $10,000 of interest paid on a loan for a new vehicle assembled in the United States. It applies to tax years 2025 through 2028 and is claimed on Schedule 1-A (Form 1040).
Who qualifies for the car loan interest deduction?
Taxpayers who financed a new vehicle assembled in the United States after December 31, 2024, for personal use, and whose MAGI is below the phase-out threshold ($100,000 single / $200,000 married filing jointly) may qualify. The vehicle must weigh less than 14,000 pounds GVWR and the loan must be secured by a first lien.
How do I check if my car was assembled in the USA?
You can check by looking at the first character of your VIN (1, 4, or 5 typically indicates US assembly) or by using the NHTSA VIN decoder. The final regulations also allow verification through the final assembly point reported on the label affixed to the vehicle.
Does a lease qualify for the car loan interest deduction?
No. Leased vehicles do not qualify. The deduction applies only to interest paid on a loan used to purchase a vehicle, not to lease payments.
Does a used car qualify for the deduction?
No. The QPVLI deduction applies only to new vehicles where the original use begins with the taxpayer. Used vehicles and vehicles purchased at the end of a lease do not qualify.
What is the income limit for the car loan interest deduction?
The deduction begins to phase out at MAGI above $100,000 for single filers and $200,000 for married filing jointly. It is fully phased out at $150,000 for single filers and $250,000 for joint filers.
How does the income phase-out work?
For every $1,000 that your MAGI exceeds the threshold, your deduction is reduced by $200. The reduction cannot bring the deduction below zero. The phase-out threshold is $100,000 for single filers and $200,000 for married filing jointly.
Is the deduction available if I take the standard deduction?
Yes. The QPVLI deduction is an above-the-line deduction reported on Schedule 1-A. It is available whether you itemize or take the standard deduction.
Does my Tesla qualify for the car loan interest deduction?
It depends on where your specific Tesla was assembled. Tesla vehicles assembled in the United States (such as Model Y and Model 3 produced at US factories) may qualify if purchased new and financed. Verify your VIN to confirm assembly location.
Does refinancing affect eligibility for the car loan interest deduction?
In most cases, refinancing does not disqualify the deduction as long as the original loan and vehicle meet the eligibility requirements. The final regulations address refinancing treatment. Consult a tax professional for your specific situation.
Can I claim the deduction for multiple vehicles?
The $10,000 cap applies per return, regardless of how many qualifying vehicles you financed. There is no limit on the number of loans you may claim, but the total deduction cannot exceed $10,000 per year.
What is Form 1098-VLI?
Form 1098-VLI is the Vehicle Loan Interest Statement that lenders use to report qualified passenger vehicle loan interest of $600 or more to the IRS and the borrower. It helps taxpayers substantiate the interest paid when claiming the deduction.
When does the car loan interest deduction expire?
Under current law, the deduction applies to tax years 2025 through 2028 and expires after tax year 2028. No extension has been enacted at the time of publication.

Methodology and Sources
Methodology: This article and the accompanying calculator apply the verified statutory and regulatory rules for the Qualified Passenger Vehicle Loan Interest deduction. The deduction is capped at $10,000 per return per year. The income phase-out is calculated as $200 per $1,000 (or portion thereof) by which MAGI exceeds $100,000 (single) or $200,000 (married filing jointly). The phase-out cannot reduce the deduction below zero. Tax savings estimates are calculated by multiplying the final deductible amount by the user's marginal tax rate; actual savings depend on individual tax circumstances.
Assumptions: The calculator assumes the vehicle is new, assembled in the United States, used for personal use, and financed with a first-lien loan. It assumes the user's MAGI is accurately entered. It does not account for state income tax treatment, alternative minimum tax, or other tax provisions that may affect the actual deduction or savings.
