To claim the OBBBA car loan interest deduction on your 2026 return, get your year-end interest statement from your auto lender, confirm the vehicle was new and US-assembled at time of purchase, and enter the interest amount (up to $10,000) on Schedule 1 of Form 1040. No itemizing required. The deduction phases out above MAGI $100,000 (single) or $200,000 (married filing jointly).
KEY TAKEAWAYS
- Deduction cap: $10,000 of auto loan interest paid in 2026. Above-the-line, no itemizing needed.
- Vehicle must have been new and US-assembled at the time of purchase. Used vehicles and foreign-assembled models do not qualify.
- MAGI phase-out: $100,000 single / $200,000 joint (-$100 per $1,000 over threshold through $200k/$300k).
- Your documentation is the lender’s annual interest statement, similar to the Form 1098 you get for mortgage interest. The IRS may issue a specific auto interest form; verify at irs.gov in fall 2026.
- The deduction covers interest paid in 2026 only, not principal, fees, or interest from prior years.
- Business vehicles use a different deduction method (Section 179 / depreciation). This deduction is for personal-use vehicles only.
Does Your Vehicle Qualify?
Three conditions must all be true. Check each one before you pull your lender statement:
| Condition | Qualifies | Does Not Qualify |
|---|---|---|
| Vehicle type | New passenger car, SUV, truck, or van purchased for personal use | Used vehicle, leased vehicle, motorcycle, RV |
| Assembly location | Final assembly in the United States | Vehicle assembled outside the US (even US brands assembled abroad) |
| Use | Personal use | Business vehicle (deduct via Section 179 or depreciation instead) |
The new/used and personal-use conditions are straightforward. The assembly location requirement takes one extra step.
How to Confirm Your Car Was US-Assembled
Assembly location is determined by the final assembly plant, not the brand’s home country. A Toyota Camry assembled in Kentucky qualifies. A Ford Explorer assembled in Canada does not. Here is how to check:
- Window sticker (Monroney label): The sticker that came with your new car lists the final assembly point. If you kept it, look for “Final Assembly Point” or “Country of Origin.” A US city and state means it qualifies.
- VIN decoder: The first character of your Vehicle Identification Number (VIN) indicates the country of manufacture. “1,” “4,” or “5” indicates the United States. You can also use the free NHTSA VIN decoder at vpic.nhtsa.dot.gov to confirm the plant address.
- Dealer documentation: Your purchase agreement or certificate of origin may also list the assembly location.
Check this before you file, not after. If your vehicle was not US-assembled, no other conditions matter, the deduction does not apply.
Does Your Loan Qualify?
The loan must be a retail installment loan or auto loan used to purchase the qualifying vehicle. Conditions:
- The loan was taken out for the purpose of buying the new US-assembled vehicle, not a personal loan used to buy a car, and not a cash-out refinance.
- The vehicle must have been purchased new. If you bought a certified pre-owned vehicle even from a dealership, it does not qualify as “new.”
- Dealer financing, bank auto loans, and credit union auto loans all qualify as long as the vehicle does.
- The deduction covers only interest paid in tax year 2026, not the principal portion of your payments, not origination fees, and not interest that accrued in prior years.
Step 1: Get Your Year-End Lender Interest Statement
Your auto lender should send you an annual statement showing the total interest you paid on your loan in 2026. For mortgage loans, this is the familiar Form 1098. Auto loan interest reporting is newer, and the IRS may issue a standardized form for 2026, check irs.gov in fall 2026 and contact your lender if you have not received a statement by late January 2027.
What to look for on the statement:
- Total interest paid in 2026, the dollar figure you will enter on your return.
- Loan account number and vehicle VIN, keep these with your tax records in case the IRS asks for documentation.
If your lender does not provide an annual interest statement, you can calculate your 2026 interest from your monthly payment statements. Add up the “interest” line from each 2026 payment. Your loan amortization schedule (available from your lender or through your online account) also shows the interest breakdown by payment.
Step 2: Calculate Your Deduction Amount
Cap: You can deduct a maximum of $10,000 of auto loan interest paid in 2026, regardless of how much you actually paid. If your lender statement shows $12,000 in interest paid, you deduct $10,000.
MAGI phase-out: The phase-out thresholds for this deduction are lower than for the tips and overtime deductions:
| Filing Status | Full Deduction If MAGI ≤ | Phase-Out Rate | Fully Phased Out At |
|---|---|---|---|
| Single / Head of Household | $100,000 | –$100 per $1,000 over | $200,000 |
| Married Filing Jointly | $200,000 | –$100 per $1,000 over | $300,000 |
Example: You file single, your MAGI is $130,000, and you paid $8,500 in qualifying auto loan interest in 2026. You are $30,000 over the $100,000 threshold, so your deduction is reduced by $3,000 (30 × $100). You deduct $5,500.
If your MAGI is at or below the threshold, you deduct the full amount (up to $10,000) with no reduction.
Step 3: Enter the Deduction on Schedule 1 / Form 1040
Like the tips and overtime deductions, the car loan interest deduction is reported as an adjustment to income on Schedule 1 (Form 1040), Part II. The IRS will designate a specific line for the 2026 return when it releases the updated Schedule 1 in fall 2026, verify the line number at irs.gov before filing.
Do not confuse this with the mortgage interest deduction, which is an itemized deduction on Schedule A. The OBBBA auto loan deduction is above-the-line and goes on Schedule 1 regardless of whether you itemize.

What If You Bought the Car in 2025 or Earlier?
The deduction applies to interest paid in the tax year, not the year the car was purchased. If you bought a qualifying US-assembled new vehicle in 2023 and are still making payments in 2026, the interest portion of your 2026 payments qualifies for the deduction, as long as the vehicle was new and US-assembled when you bought it. You do not need to have bought the car in 2026.
The deduction runs through tax year 2028 under current law (IRS, 2025). As long as you are still paying interest on a qualifying loan, you can claim it each year through 2028.
Frequently Asked Questions
It depends on where it was assembled, not the brand or powertrain. A Tesla Model Y assembled at the Fremont, California factory qualifies. A Tesla Model 3 assembled in Shanghai does not. Check your VIN’s first character (must be “1,” “4,” or “5” for US assembly) or use the NHTSA VIN decoder at vpic.nhtsa.dot.gov to confirm the final assembly location of your specific vehicle.
The OBBBA car loan interest deduction is specifically for personal-use vehicles. If you use your car for business, you typically deduct auto expenses, including loan interest, through your business deductions (Schedule C or Schedule E), not through this deduction. Mixing personal and business use in a single vehicle creates a more complex tax situation; consult a CPA to determine the most advantageous approach for your split-use vehicle.
You can calculate your 2026 interest by adding up the interest portion of each monthly payment from your 2026 payment statements. Most lenders show the interest and principal breakdown on each statement. Alternatively, log in to your lender’s online portal, most provide an annual summary. Keep whatever documentation you use in case the IRS requests it. If you cannot get any documentation from your lender, contact them directly and request a year-end interest summary before you file.
Yes, they use different deduction methods and do not conflict. The OBBBA car loan interest deduction is an above-the-line adjustment to income on Schedule 1. The mortgage interest deduction is an itemized deduction on Schedule A. You can take both in the same year: the car loan deduction regardless of whether you itemize, and the mortgage deduction if you itemize rather than taking the standard deduction.
Pickup trucks, SUVs, and vans qualify as long as they meet the new and US-assembled requirements and are used for personal purposes. The deduction is not limited to passenger cars. Very large vehicles classified as heavy-duty commercial trucks may be treated differently, check with a tax professional if your vehicle has a GVWR (gross vehicle weight rating) over 6,000 lbs, as that classification can affect available deductions.
Bottom line: The car loan interest deduction is the most documentation-intensive of the four new OBBBA deductions, but it is straightforward if your vehicle was new and US-assembled. Get your lender’s interest statement, confirm the VIN, and enter up to $10,000 on Schedule 1. Tax software handles the phase-out math.

IRS documentation requirements and form numbers for tax year 2026 are not yet finalized, verify at irs.gov before filing and consult a CPA or tax professional for your specific situation, especially for mixed personal/business vehicle use.
