No Tax on Car Loans: The OBBBA Auto Loan Interest Deduction Explained
The One Big Beautiful Bill Act (OBBBA) added a new above-the-line deduction for domestic auto loan interest — up to $10,000 per year, no itemizing required. Here is what qualifies, which vehicles count, and how to claim it on Schedule 1-A Part IV.
What Is the Car Loan Interest Deduction?
Before the OBBBA, personal auto loan interest was not deductible on federal taxes. The mortgage interest deduction existed, but car loans were treated as personal expenses with no tax benefit.
The OBBBA changed that. Starting with the 2025 tax year (returns filed in 2026), taxpayers can deduct interest paid on a personal auto loan for a domestically assembled vehicle — up to $10,000 per year. The deduction is claimed on the new Schedule 1-A, Part IV, which attaches to Form 1040.
Critically, this is an above-the-line deduction. You do not need to itemize. Every qualifying taxpayer can claim it — whether they take the standard deduction or itemize on Schedule A.
Who Qualifies?
Three requirements must all be met:
1. You Have a Loan, Not a Lease
Only loan interest qualifies. A lease payment is not interest — it is a rental fee. If you are leasing your vehicle, Part IV does not apply. If you purchased your vehicle with a loan from a bank, credit union, dealer financing, or any other lender, you are in the right category.
2. The Vehicle Has Final Assembly in the USA
The statute requires final assembly to occur in the United States. Brand country of origin does not matter. A Toyota assembled in Georgetown, KY qualifies. A Chevrolet assembled in Mexico does not. See the section below on verifying your vehicle.
3. Personal Use Vehicle
The deduction is for personal auto loans. Vehicles used exclusively for business should still go through Schedule C or Form 4562. A vehicle used for both personal and business use may be subject to allocation rules — consult a tax professional if this applies to you.
There is no income limit for Part IV, unlike the tips and overtime deductions (which phase out at $150,000/$300,000). Any taxpayer with a qualifying loan can claim it regardless of income.
Which Vehicles Count as "Domestic"?
"Domestic" under the OBBBA means final assembly in the United States — not brand headquarters, not where components are made, but where the vehicle is put together as a finished product.
Confirmed Domestic Brands (Most Models)
The following brands assemble the majority of their US-sold vehicles in American plants: Ford, Chevrolet, GMC, Buick, Cadillac, Lincoln, Chrysler, Dodge, Jeep, Ram, Tesla, Rivian, and Lucid. For these brands, most — but not all — models qualify. Always confirm the specific model year.
Foreign Brands with US Plants
Several foreign-headquartered manufacturers assemble vehicles in the United States. These models qualify even though the brand is not American:
- Toyota Camry, Avalon (Georgetown, KY)
- Toyota Tundra, Sequoia (San Antonio, TX)
- Honda Accord, CR-V, Passport (Marysville / East Liberty, OH)
- BMW X3, X4, X5, X6, X7 (Spartanburg, SC)
- Mercedes GLE, GLS (Vance, AL)
- Volkswagen Atlas, ID.4 (Chattanooga, TN)
How to Verify Your Specific Vehicle
Two fast methods: (1) Check the Monroney window sticker for the line labeled "Final Assembly Point." (2) Run your 17-character VIN through the free NHTSA VIN decoder. VINs starting with 1, 4, or 5 indicate US assembly; starting with 2 is Canada; starting with 3 is Mexico.
How Much Can You Deduct?
You deduct the actual interest you paid during the tax year, up to $10,000. Your lender reports the total interest paid on Form 1098 or an equivalent annual statement.

How to Claim — Schedule 1-A Part IV
The process is straightforward if you have the right documents:
- Collect your interest statement. Auto lenders are required to provide an annual statement (often Form 1098 or a year-end account summary) showing total interest paid during the year.
- Verify domestic assembly. NHTSA VIN lookup or window sticker, as described above.
- Complete Schedule 1-A Part IV. Enter your qualifying interest (capped at $10,000). If you have two domestic auto loans, combine their interest before applying the cap.
- Attach to Form 1040. The Schedule 1-A total flows through Schedule 1, Part II into your adjusted gross income calculation — reducing your taxable income directly.

Can You Combine with Other OBBBA Deductions?
Yes — and this is one of the most valuable aspects of Schedule 1-A. All four OBBBA deductions are claimed on the same form and stack on top of each other:
- Part I: No Tax on Seniors (age 65+, income limits apply)
- Part II: No Tax on Tips (up to $25,000, tipped workers)
- Part III: No Tax on Overtime (FLSA-covered employees)
- Part IV: No Tax on Car Loans (up to $10,000, domestic vehicles)
A tipped worker with a qualifying car loan can claim both Part II and Part IV on the same Schedule 1-A. An overtime worker who is also 65+ can claim Parts I, III, and IV simultaneously.

Frequently Asked Questions
Is there an income limit for the car loan deduction?
No. Unlike the tips and overtime deductions (which phase out at $150,000 for single filers), Part IV has no income limit. A taxpayer earning $300,000 with a qualifying domestic auto loan can still claim the full $10,000 deduction.
Does refinancing my car loan affect the deduction?
No — the deduction is based on interest actually paid during the tax year, regardless of how many times the loan has been refinanced. Interest paid to the new lender after refinancing counts just as the interest paid to the original lender did. Gather year-end statements from each lender to capture all interest paid during the year.
What if I paid off my car loan mid-year?
You can deduct all interest paid during the portion of the year the loan was active. If you paid $1,800 in interest before paying off the loan in June, you claim $1,800. The $10,000 cap rarely comes into play in this scenario.
