What Is the OBBBA Car Loan Interest Deduction?
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, introduced a brand-new federal income tax deduction for interest paid on auto loans for vehicles assembled in the United States. Starting with the 2026 tax year, qualifying taxpayers can deduct up to $10,000 per year in auto loan interest from their federal taxable income.
This provision joins the no-tax-on-tips and no-tax-on-overtime deductions as one of the OBBBA's signature tax relief measures. While those provisions target specific types of workers, the car loan interest deduction is available to any taxpayer who finances a US-assembled vehicle — regardless of occupation.

Who Qualifies for the Car Loan Interest Deduction?
To claim the deduction, you must meet all of the following criteria:
- US-assembled vehicle: The car, truck, or SUV must have been final-assembled in the United States, verified by the Vehicle Identification Number (VIN)
- Bona fide auto loan: The vehicle must be financed through a qualifying auto loan — not a lease, personal loan, or home equity line
- Income under the phase-out ceiling: MAGI below $110,000 (single) or $210,000 (married filing jointly) for any benefit
- Loan must be in your name: You or your spouse (if filing jointly) must be the borrower on the loan
Who does NOT qualify:
- Taxpayers who lease their vehicle (lease payments are not interest)
- Owners of vehicles assembled outside the US (imported vehicles)
- Taxpayers who paid cash (no loan = no interest to deduct)
- Borrowers using personal loans, HELOCs, or credit cards to finance a vehicle
- Single filers with MAGI above $110,000 or MFJ filers above $210,000
Which Vehicles Are Assembled in the US?
The fastest way to check is the first character of your VIN:
| VIN Starts With | Assembly Country | Qualifies? |
|---|---|---|
| 1, 4, or 5 | United States | Yes |
| 2 | Canada | No |
| 3 | Mexico | No |
| J | Japan | No |
| K | South Korea | No |
| W | Germany | No |
Popular US-Assembled Vehicles
| Vehicle | Assembly Location | Starting MSRP |
|---|---|---|
| Ford F-150 | Dearborn, MI | $36,000 |
| Toyota Camry | Georgetown, KY | $29,500 |
| Honda Accord | Marysville, OH | $29,300 |
| Tesla Model 3 | Fremont, CA | $38,990 |
| Tesla Model Y | Austin, TX | $44,990 |
| Chevrolet Silverado | Fort Wayne, IN | $38,600 |
| BMW X5 | Spartanburg, SC | $63,200 |
| Hyundai Santa Fe | Montgomery, AL | $34,500 |
| Honda CR-V | Greensburg, IN | $32,400 |
| Toyota RAV4 | Georgetown, KY | $31,400 |
Always confirm with the NHTSA VIN decoder or the window sticker, as assembly locations can change between model years.
How Much Can You Save? Savings by Loan Scenario
The following table shows estimated first-year federal tax savings for common loan scenarios, assuming single filing status and income below the phase-out threshold:
| Loan Amount | APR | Term | Year 1 Interest | Tax Bracket | Annual Savings |
|---|---|---|---|---|---|
| $20,000 | 6.5% | 48 months | $1,220 | 12% | $146 |
| $25,000 | 7.0% | 60 months | $1,650 | 12% | $198 |
| $30,000 | 7.5% | 60 months | $2,120 | 22% | $466 |
| $35,000 | 7.0% | 60 months | $2,310 | 22% | $508 |
| $40,000 | 8.0% | 60 months | $3,020 | 22% | $664 |
| $50,000 | 7.5% | 72 months | $3,540 | 22% | $779 |
| $60,000 | 8.0% | 72 months | $4,530 | 24% | $1,087 |
| $80,000 | 8.5% | 72 months | $6,410 | 24% | $1,538 |
Higher interest rates and longer terms mean more deductible interest in the early years of the loan. Workers in higher tax brackets save more per dollar of interest.

Income Phase-Out Rules
The deduction is not available to all income levels. The OBBBA phases out the benefit for higher earners:
| Filing Status | Full Deduction | Phase-Out Begins | Fully Eliminated |
|---|---|---|---|
| Single | MAGI ≤ $100,000 | $100,001 | $110,000 |
| Married Filing Jointly | MAGI ≤ $200,000 | $200,001 | $210,000 |
| Married Filing Separately | MAGI ≤ $100,000 | $100,001 | $110,000 |
| Head of Household | MAGI ≤ $100,000 | $100,001 | $110,000 |
The phase-out is dollar-for-dollar. For every $1 of MAGI above the threshold, the $10,000 cap is reduced by $1. This means a single filer at $105,000 has a reduced cap of $5,000, and a single filer at $110,000 or above gets zero deduction.
Phase-Out Example
A single filer earning $103,000 with a $40,000 auto loan at 7.5% APR:
- Annual interest: ~$2,830
- MAGI exceeds threshold by $3,000
- Adjusted cap: $10,000 - $3,000 = $7,000
- Deductible interest: $2,830 (actual interest is under the adjusted cap)
- At 24% bracket: $2,830 × 24% = $679 savings
In this case, the phase-out does not materially affect the taxpayer because their actual interest is well below even the reduced cap.
How to Claim the Deduction on Your 2026 Tax Return
- Receive Form 1098-AUTO: Your lender will issue this new IRS form by January 31, 2027, reporting the total interest paid on your qualifying auto loan during 2026.
- Verify VIN qualification: Confirm your vehicle was final-assembled in the US using the NHTSA VIN decoder. You will need to enter the VIN on your tax return.
- Complete Schedule 1 (Form 1040): Enter the deductible auto loan interest amount as an above-the-line adjustment to income.
- No itemization required: This is an above-the-line deduction — you benefit whether you take the standard deduction or itemize.
- Keep documentation: Save your 1098-AUTO, loan agreement, and vehicle purchase documents (including the window sticker or VIN confirmation) in case of an IRS inquiry.
Car Loan Interest Deduction vs. Mortgage Interest Deduction
The OBBBA car loan interest deduction works differently from the familiar mortgage interest deduction:
| Feature | Car Loan Interest (OBBBA) | Mortgage Interest |
|---|---|---|
| Annual Cap | $10,000 | Interest on up to $750K debt |
| Requires Itemizing? | No (above-the-line) | Yes (Schedule A) |
| Income Phase-Out | $100K/$200K | None |
| Vehicle/Property Requirement | US-assembled only | Primary or secondary home |
| Permanent? | No (2026-2028) | Yes (ongoing) |
| Form Reported On | 1098-AUTO | 1098 |
The key advantage of the car loan deduction is that it is above-the-line — you do not need to itemize. This makes it accessible to the roughly 90% of taxpayers who take the standard deduction and cannot benefit from the mortgage interest deduction.
Combining With Other OBBBA Deductions
The car loan interest deduction stacks with every other OBBBA provision. Here is how a worker could potentially benefit from multiple deductions:
- No tax on tips: Up to $25,000 in tips exempt (income under $160K)
- No tax on overtime: Up to $12,500 in overtime premium deductible
- Car loan interest: Up to $10,000 deductible (income under $100K/$200K)
- SALT cap increase: Up to $40,400 (was $10,000)
- Child tax credit: $2,500 per child (was $2,000)
- Senior bonus: $4,000 additional deduction (age 65+)

Should You Buy a US-Assembled Vehicle to Get the Deduction?
The deduction should not be the primary reason to buy a car. Consider the math:
- A $35,000 loan at 7% produces about $2,300 in first-year interest
- At the 22% bracket, that saves $506 in taxes
- Over 3 years (before sunset), total savings are approximately $1,300
- The total interest paid over the life of the loan is $6,500+
You are still paying significantly more in interest than you are saving in taxes. The deduction reduces the cost of borrowing — it does not make borrowing free. If you are already planning to buy a vehicle and are choosing between a US-assembled and imported model, the deduction could tip the scale. But taking on a car loan solely for the tax benefit is rarely a sound financial decision.
Common Misconceptions
"All car loan interest is deductible"
Only interest on loans for US-assembled vehicles qualifies. Imported vehicles, even from US brands, do not qualify if assembled outside the US.
"The deduction eliminates all taxes on my car payment"
The deduction only applies to the interest portion of your payment, not the principal. And it only reduces federal income tax — not sales tax, registration fees, or state income tax.
"Lease payments count as interest"
Leases do not qualify. You must hold title to the vehicle and pay interest on a qualifying auto loan.
"The deduction is permanent"
No. It applies only to tax years 2026-2028 and will sunset unless Congress acts. Plan your vehicle purchase timing accordingly.
"I need to itemize to claim this"
No. The car loan interest deduction is above-the-line. You can claim it alongside the standard deduction.

Bottom Line
The OBBBA car loan interest deduction is a new tax benefit for millions of Americans who finance US-assembled vehicles. While the savings are more modest than the tips or overtime deductions for most borrowers — typically $200 to $1,500 per year depending on loan size, rate, and tax bracket — the above-the-line treatment makes it accessible to nearly every qualifying taxpayer.
The biggest benefits go to borrowers with larger loans, higher interest rates, and incomes in the 22-24% bracket range below the phase-out threshold. If you already have a qualifying vehicle and an auto loan, the deduction is essentially free money — just claim it when filing your 2026 return.
