As of April 7, 2026, American car owners have just 8 days left before the April 15, 2026 tax deadline to claim the new IRS OBBB $10,000 car loan interest deduction introduced under the One Big Beautiful Bill Act. If you purchased a US-assembled vehicle in 2025 and financed it, you may be able to deduct up to $10,000 in auto loan interest directly on your federal return — potentially saving $2,200–$3,700 in taxes at the 22–37% brackets. Here is everything you need to check eligibility, verify your VIN, and file before the deadline.
What Is the OBBB $10,000 Car Interest Deduction?
The One Big Beautiful Bill (OBBB) Act, signed into law in late 2025, introduced a new above-the-line deduction allowing taxpayers to deduct up to $10,000 of interest paid on auto loans for new vehicles assembled in the United States. Unlike the mortgage interest deduction, this car loan deduction applies whether you itemize or take the standard deduction — making it available to virtually every qualifying taxpayer.
The deduction applies to interest paid during tax year 2025 on loans originated on or after January 1, 2025. If you financed a US-made vehicle in early 2025, your 2025 interest paid could be anywhere from $1,200 to $4,800 depending on loan size and rate — and all of it may be deductible up to the $10,000 cap.
Do You Qualify? The 3-Part OBBB Car Deduction Test
1. Vehicle Assembly — VIN Check for US Origin
The vehicle must be final-assembled in the United States. The fastest way to verify: look at the first character of your VIN. VINs starting with 1, 4, or 5 indicate US assembly. VINs beginning with J (Japan), W (Germany), or K (South Korea) do not qualify for this deduction regardless of brand.
Common qualifying vehicles include the Ford F-150 (built in Dearborn, MI), Tesla Model Y and Model 3 (Fremont, CA and Austin, TX), Chevrolet Silverado (Fort Wayne, IN), and Toyota Camry (Georgetown, KY). You can confirm assembly location using the NHTSA VIN decoder at nhtsa.gov.
2. Income Limits — $100k–$200k Phase-Out
The $10,000 deduction begins phasing out at $100,000 MAGI for single filers and $200,000 for married filing jointly. The deduction reduces by $1 for every $2 of income above these thresholds and is completely eliminated at $120,000 (single) / $220,000 (MFJ). If your income falls within the phase-out range, calculate your partial deduction amount before filing.
3. Loan Must Be a Consumer Auto Loan
The interest must be on a loan specifically for vehicle purchase — not a home equity loan used to buy a car, a business vehicle loan (which follows different rules under Section 179), or a lease. Dealership financing, bank auto loans, and credit union vehicle loans all qualify as long as the vehicle meets the assembly test.
How Much Will You Actually Save?
Your tax savings depend on your marginal bracket and how much interest you paid in 2025. Here are realistic estimates for a $45,000 vehicle financed at 7.5% over 72 months (approximately $2,900 in year-1 interest):
- 22% bracket ($47k–$100k income): $2,900 deduction × 22% = $638 saved
- 24% bracket ($100k–$191k): $2,900 × 24% = $696 saved
- 32% bracket ($191k–$243k, partial phase-out): Reduced deduction applies
For higher-balance loans — say $75,000 at 8.5% for a truck or luxury SUV — year-1 interest can exceed $6,000, pushing your savings close to $1,400–$2,200 depending on bracket.
Step-by-Step: How to Claim the OBBB Car Deduction on Form 1040
- Get your 1098 or lender interest statement: Your auto lender should have issued a 2025 interest statement. If you haven't received one, log into your lender portal — most banks (Chase Auto, Wells Fargo, Capital One Auto) show annual interest paid in the account summary.
- Verify VIN eligibility: Use the NHTSA decoder or your vehicle's title — confirm first VIN digit is 1, 4, or 5 and that the manufacturing plant listed is in a US state.
- Complete the OBBB Vehicle Interest Worksheet: This IRS worksheet (included with the 2025 Form 1040 instructions, page 34) calculates your deductible amount after applying the income phase-out.
- Enter on Schedule A (or Form 1040 Line 20b): The OBBB auto interest deduction is entered on Schedule A if itemizing, or on the newly added Line 20b if taking the standard deduction. Both paths reduce your adjusted gross income for the purposes of this deduction.
- File by April 15, 2026: No extension available for this deduction on 2025 returns — the filing deadline is the claim deadline. If you file an extension, you can still claim it on the extended return, but any tax owed is still due April 15.

Frequently Asked Questions
Can I claim the OBBB car deduction if I already filed?
Yes — file an amended return using Form 1040-X. You have up to 3 years from the original due date to amend. However, if you haven't filed yet for 2025, include the deduction in your original return before April 15 to avoid the amendment process entirely.
Does a used car purchase qualify for the OBBB deduction?
No — the OBBB auto interest deduction applies only to new vehicles purchased on or after January 1, 2025. Used car loans, even for US-assembled vehicles, do not qualify under the current statutory language.
What if I refinanced my auto loan in 2025?
Interest paid on a refinanced auto loan qualifies as long as the vehicle itself meets the US-assembly requirement and was originally purchased new. The refinance date does not reset the purchase eligibility — use your original purchase date and the assembly location of the vehicle.
With only 8 days remaining before April 15, there is still enough time to verify your VIN, pull your interest statement, and claim this deduction — potentially putting hundreds to thousands of dollars back in your pocket.
