1. The Big Picture: What Changed and Why It Matters

For nearly four decades — since the Tax Reform Act of 1986 — personal car loan interest was simply not deductible on your federal tax return. You could deduct mortgage interest. You could deduct student loan interest. But the interest on the car you drove to work every morning? That was gone.

That changed in 2025. The “No Tax on Car Loan Interest” provision of the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, brought this new deduction to American taxpayers.For nearly 40 years, personal car loan interest had been off-limits as a tax deduction. That changed with the One Big Beautiful Bill Act (P.L. 119-21, 7/4/2025), which temporarily allows the deduction under IRC Sec. 163(h)(4). For tax years 2025–2028, up to $10,000 of qualified passenger vehicle loan interest per year is deductible — whether you itemize or take the standard deduction.

For tax year 2026, this deduction is fully active, and for the first time, your lender is officially required to send you a brand-new tax document — Form 1098-VLI — to help you claim it. This makes filing the deduction on your 2027 return more straightforward than it was during the 2025 transition year.

2. The Law Behind It: OBBBA and IRC § 163(h)(4)

The car loan interest deduction is a temporary federal tax benefit that allows eligible taxpayers to deduct interest paid on qualifying new vehicle loans. Congress enacted this provision to encourage domestic vehicle manufacturing and ease the financial burden of purchasing a new car.

This provision contains proposed amendments to the Income Tax Regulations under sections 163 and 6050AA of the Internal Revenue Code, as amended and enacted by section 70203(a) and (c)(1) of Public Law 119-21 (July 4, 2025), related to the allowance of a federal income tax deduction under section 163(a) and (h)(4) for qualified passenger vehicle loan interest (QPVLI) and certain information reporting requirements under section 6050AA.

In plain English: Congress wrote a brand-new rule into the tax code that says car loan interest — specifically on new, US-assembled vehicles used for personal purposes — is now allowed as a deduction, starting with loans taken out after December 31, 2024, and running through December 31, 2028.

The Treasury and IRS provided guidance on the “No Tax on Car Loan Interest” provision enacted under the One Big Beautiful Bill. The proposed regulations relate to a new deduction for interest paid on vehicle loans incurred after Dec. 31, 2024, to purchase new made-in-America vehicles for personal use. This new tax benefit applies to both taxpayers who take the standard deduction and those who itemize deductions.

3. Who Qualifies? Full Eligibility Breakdown

This is not a deduction that everyone with a car loan gets automatically. There are specific boxes you must check. It does not automatically provide a tax break for interest on every car loan. Instead, only new car buyers who meet a specific set of qualifications can benefit.

Here is a clear checklist of the requirements you must meet for your 2026 tax year return filed in 2027:

• ✅ The vehicle must be brand new — used vehicles do not qualify.
• ✅ The vehicle’s final assembly must have occurred in the United States.
• ✅ The vehicle must be a qualifying passenger vehicle (car, minivan, van, SUV, pickup truck, or motorcycle with a GVWR under 14,000 lbs).
• ✅ The loan must have been originated after December 31, 2024.
• ✅ The loan must be a first lien secured by the qualifying vehicle.
• ✅ The vehicle must be used for personal purposes — not commercial or fleet use.
• ✅ You must be below the MAGI income limits (or accept a partial deduction if you’re within the phase-out range).
• ✅ You must report the VIN of the vehicle on your tax return.

Individuals may deduct interest paid on a loan used to purchase a qualified vehicle, provided the vehicle is purchased for personal use and meets other eligibility criteria. Lease payments do not qualify. The maximum annual deduction is $10,000. The deduction phases out for taxpayers with modified adjusted gross income over $100,000 ($200,000 for joint filers).

4. Which Vehicles Qualify? The US Assembly Requirement Explained

This is the part where many taxpayers get tripped up. Just because a car brand is American doesn’t mean it was built in America.

Ford builds the Maverick pickup and Bronco Sport SUV in Mexico, while Dodge’s Charger Daytona EV is manufactured in Canada, so none of those vehicles would qualify for this tax break.

Meanwhile, a number of foreign brands that sell vehicles in the United States have factories in America. Honda produces the Accord in Marysville, Ohio, while Toyota assembles the Camry, RAV4, and Lexus ES in Georgetown, Kentucky, to name a few.

How to Check If Your Vehicle Was Assembled in the USA:

1. Check the window sticker (Monroney label): The final assembly location is listed on the vehicle’s window sticker or in sales material.
2. Check the VIN: Check the car’s vehicle identification number (VIN). A VIN beginning with 1, 4, 5, 7F–7Z, or 70 came from a U.S. assembly plant.
3. Use Online Tools: Use AutoCheck or Carfax to learn more about the history of the car in question, or use the VIN Decoder from the National Highway Traffic Safety Administration (NHTSA) to confirm the car’s assembly location.

Qualifying Vehicle Types: Eligible vehicles include cars, SUVs, vans, pickups, and motorcycles under 14,000 lbs GVWR, with final assembly in the U.S.

5. Loan Requirements: What Kind of Loan Qualifies?

Not just any auto loan qualifies. The IRS has specific rules about the type of loan and how it must be structured.

• The loan must be used to purchase the qualifying vehicle — not a personal loan, home equity loan, or line of credit used for the same purpose.
• The loan must be a first lien on the vehicle. Do not file Form 1098-VLI unless the loan was secured by a first lien on the APV (applicable passenger vehicle) at the time the loan was made.
• The loan must have originated after December 31, 2024. Loans taken out before that date do not qualify, even if you’re still paying interest on them in 2026.
• The vehicle must be new at the time of purchase — meaning the original use of the vehicle must start with the taxpayer; used vehicles do not qualify.
• Lease payments do not count. The vehicle must be purchased for personal use. Lease payments do not qualify.

What About Refinanced Loans? If you refinanced your qualifying car loan, you may still be able to claim the deduction. If you refinance a car loan, you still may be able to deduct interest paid on the new loan. However, you can only deduct the interest from a refinanced loan if both the original loan and the related vehicle met all of the deduction’s requirements. The new loan also must be secured by a first lien on the same vehicle. However, you can only deduct interest paid on the outstanding balance of the new loan as of the date of the refinancing.

Can You Use Any Lender? Yes. There are no restrictions on the lender type — bank, credit union, manufacturer financing, or other.

---

6. Income Limits and Phase-Out: Does Your Salary Affect the Deduction?

Yes. How much you can deduct depends on your Modified Adjusted Gross Income (MAGI). Think of MAGI as your total income after certain deductions — it’s close to your regular adjusted gross income (AGI) in most cases, but check with your tax professional for your exact number.

Here are the income thresholds for the 2026 tax year:

Filing Status	Full Deduction (Up to $10,000)	Phase-Out Begins At	Deduction Fully Gone At
Single / Head of Household	MAGI ≤ $100,000	MAGI > $100,000	MAGI ≥ $150,000
Married Filing Jointly	MAGI ≤ $200,000	MAGI > $200,000	MAGI ≥ $250,000

Your deduction would be reduced by $200 for every $1,000 that your MAGI is above the phase-out’s lower threshold.

The deduction is reduced by $200 for every $1,000 above the threshold, and is completely phased out at $150,000 for single filers and $250,000 for married filing jointly filers.

7. Real-Life Examples With Actual Numbers

Let’s look at how this deduction plays out in three real-world situations for tax year 2026.

Example 1: Full Deduction — Under the Income Limit

Maria, Single filer in Ohio

• Bought a 2026 Honda Accord (assembled in Marysville, Ohio) in March 2025
• Loan amount: $35,000 at 7% APR over 60 months
• Total interest paid in 2026: approximately $2,200
• MAGI: $72,000
• Deductible Amount: $2,200 (full amount — no phase-out applies)
• At a 22% tax bracket: Tax savings = $484

Example 2: Partial Deduction — Within the Phase-Out Range

James, Single filer in Texas

• Bought a 2026 Ford F-150 (assembled in Dearborn, Michigan) in July 2025
• Loan amount: $55,000 at 6.5% APR over 72 months
• Total interest paid in 2026: approximately $3,400
• MAGI: $120,000
• MAGI exceeds $100,000 threshold by $20,000
• Phase-out reduction: $20,000 ÷ $1,000 = 20 units × $200 = $4,000 reduction
• Since the actual interest paid ($3,400) is less than the $4,000 reduction, James’s deduction is $0. His income puts him just over the line for this amount of interest paid. However, if his interest were higher — say $8,000 — his allowed deduction would be $8,000 − $4,000 = $4,000.

Example 3: Married Couple — Joint Filers Close to Phase-Out

The Garcias — Married Filing Jointly in California

• Bought a 2026 Toyota Camry (assembled in Georgetown, Kentucky) in January 2026
• Loan amount: $42,000 at 6% APR over 60 months
• Total interest paid in 2026 (full year): approximately $2,400
• Combined MAGI: $210,000
• MAGI exceeds $200,000 threshold by $10,000
• Phase-out reduction: $10,000 ÷ $1,000 = 10 × $200 = $2,000 reduction
• Allowed deduction: $2,400 − $2,000 = $400 deductible
• At 22% tax bracket: Tax savings = $88

The takeaway: The deduction delivers the most value to single filers earning under $100,000 and joint filers earning under $200,000. The further your income climbs above those limits, the less you benefit.

8. How to Claim This Deduction on Your 2026 Return (Filed in 2027)

This is an above-the-line deduction, which is one of the best types of deductions you can get. The new car loan interest write-off is an “above-the-line” deduction. That means you can claim the deduction to reduce your income before calculating your adjusted gross income (AGI), even if you choose to take the standard deduction instead of itemizing.

Here is exactly how to file it on your 2027 return for tax year 2026:

Step 1: Collect Your Form 1098-VLI

Starting with the 2026 tax year, your lender is required to send you a Form 1098-VLI if you paid at least $600 of qualified interest during the tax year. The form will show the amount of interest paid during the year and other information you may need to claim the car loan interest deduction.

Your lender must mail or electronically deliver Form 1098-VLI to you by January 31, 2027. Unlike the 2025 transition year when lenders could use a simple statement, for tax year 2026 onwards, the official Form 1098-VLI is required.

Step 2: Verify the VIN on Your Form 1098-VLI

When you receive Form 1098-VLI, verify that the VIN reported matches your vehicle and that the interest amount is accurate before entering it on Schedule 1-A.

Step 3: Complete Schedule 1-A

To claim the vehicle loan interest deduction, complete Form 1040, Schedule 1-A (Additional Deductions), Part IV — titled “No Tax on Car Loan Interest.” Confirm the vehicle underwent final assembly in the U.S. and enter its VIN. Enter the total vehicle loan interest paid for the tax year. Apply the phase-out calculation to arrive at your allowable deduction amount.

Step 4: Attach Schedule 1-A to Your Form 1040

Schedule 1-A totals flow to Form 1040, just like other adjustments to income.Submit Schedule 1-A together with your Form 1040 when you file your 2026 return in 2027.

Step 5: Apply the Phase-Out if Applicable

If your MAGI is above $100,000 (single) or $200,000 (joint), you’ll need to calculate your reduced deduction using the $200 per $1,000 formula before entering the final number on Schedule 1-A. Your tax software should handle this calculation automatically.

9. The New Form 1098-VLI: What to Expect From Your Lender in 2027

The IRS created a brand-new tax form specifically for this deduction. The IRS created Form 1098-VLI (Vehicle Loan Interest) specifically for IRC § 163(h)(4) reporting. Lenders originating qualifying motor vehicle loans are required to file Form 1098-VLI and provide a copy to the borrower starting with Tax Year 2026.

Here’s what your Form 1098-VLI will show when you receive it in early 2027:

• Box 1: Total vehicle loan interest received by lender during 2026
• Box 2a/2b/2c: Year, Make, and Model of the vehicle
• Box 2d: VIN (Vehicle Identification Number)
• Box 3a: Loan origination date
• Box 4: Outstanding principal balance
• Box 5: Refund of overpaid interest (if any)

Borrowers have never received a Form 1098-VLI before. Many will not recognize it, and lenders should expect questions unless expectations are set in advance.So when you see this new form in your mailbox or in your online banking portal in January 2027, don’t be surprised — that’s your documentation for the car loan interest deduction on your 2026 return.

10. What Does NOT Qualify — Common Pitfalls

Knowing what doesn’t qualify can save you from a future IRS problem. Here are the most common situations where people wrongly think they qualify:

• ❌ Used vehicles: Used vehicles don’t count.The original use of the vehicle must start with you.
• ❌ Lease payments: Lease payments do not qualify.You must own the vehicle through a purchase loan.
• ❌ Business or commercial vehicles: Vehicles used for commercial, fleet, or business purposes (other than as an employee) generally do not qualify.
• ❌ Vehicles assembled outside the US: If the vehicle’s final assembly did not happen in the United States, the deduction is zero — regardless of what brand it is.
• ❌ Loans originated before January 1, 2025: Interest on car loans taken out before this date is not deductible under this provision.
• ❌ Cash-out refinancing above the original balance: The deductible interest is limited to interest on the original qualified indebtedness. Interest attributable to cash taken out above the original loan balance in a cash-out refinance does not qualify.
• ❌ Dealer “loaner” or courtesy vehicles: Courtesy transportation vehicles are not eligible for interest tax deductions because the “original use” of the vehicle must “commence with the taxpayer.

11. How Much Can You Actually Save?

Let’s be honest about the math. While a $10,000 write-off sounds like a lot, it’s important to keep in mind that most buyers aren’t paying $10,000 in annual auto loan interest to begin with.

In 2024, the average cost of a new vehicle purchased in the U.S. was $47,640. Most interest-rate estimates place prime auto loan rates at around 6.6%. A person with a 60-month loan on this amount would pay approximately $3,100 of interest in the first year, far less than the $10,000 limit.

Here’s a simple savings calculator guide:

Annual Interest Paid	Tax Bracket	Estimated Tax Savings
$2,000	22%	$440
$3,000	22%	$660
$5,000	24%	$1,200
$8,000	24%	$1,920
$10,000	24%	$2,400

Remember — it’s still interest. A $10,000 deduction at 22% only saves $2,200. You still paid $10,000 of interest, so your net cash out is $7,800.The deduction softens the blow, but doesn’t eliminate it. Don’t finance a car you wouldn’t otherwise buy just to get this deduction.

12. State Tax Impact: Don’t Assume Your State Follows Federal Rules

Here’s something many people overlook: this is a federal deduction. Your state may not honor it. IRC § 163(h)(4) is a federal income tax provision. As of March 2026, most states have not enacted a conforming deduction. If your state has not conformed, your state taxable income remains unchanged by this deduction and you receive no state income tax benefit from the vehicle loan interest.

However, there is a silver side effect: lower federal AGI may reduce state income taxes in conforming states.Check your state’s department of revenue website or ask your tax professional whether your state follows federal rules on this new deduction.

---

13. Documents You Should Keep for Your 2026 Return

Good documentation is your best protection if the IRS ever asks questions. For your 2026 return (filed in 2027), keep the following:

• 📄 Form 1098-VLI from your lender (issued by January 31, 2027)
• 🚗 Vehicle purchase agreement or bill of sale showing the vehicle is new
• 🏭 Window sticker (Monroney label) or manufacturer’s certificate of origin confirming US final assembly
• 🔢 Vehicle Identification Number (VIN) documentation
• 📑 Loan agreement showing the loan is secured by a first lien on the vehicle
• 📊 Monthly or annual loan statements for 2026 showing interest paid

Keep your loan documents, lender interest statements, and proof of U.S. final assembly. This documentation will substantiate your deduction if the IRS questions it.

Keep the Form 1098-VLI with your tax records for at least three years after filing.

Frequently Asked Questions (FAQ)

Q1: I bought my car in 2025. Can I still deduct the interest on my 2026 return?

Yes. The deduction is available annually through 2028. That means as long as you continue to pay interest on a qualifying loan and meet the income and vehicle criteria, you’ll be able to claim this benefit on your taxes.If your loan was originated after December 31, 2024, and the vehicle qualifies, you can deduct the interest you pay on that loan each year through 2028.

Q2: Do I have to itemize deductions to claim this?

No. A taxpayer can deduct a maximum of $10,000 in interest paid per year. The claimant does not have to itemize their return to qualify for the deduction.This is an above-the-line deduction, meaning it lowers your AGI whether you take the standard deduction or itemize.

Q3: I refinanced my car loan in 2026. Do I still qualify?

Possibly. If you refinance a qualified vehicle, you are generally eligible to deduct interest you’ve paid on the refinanced amount, as long as the original loan was for personal use on a new, eligible vehicle originated after December 31, 2024. You can only deduct interest paid on the balance of the original loan. If you borrow any amount above the original balance, that interest does not qualify. The refinanced loan must be secured by a lien on the vehicle.

Q4: My car was assembled partly in the US and partly in Canada. Does it qualify?

The key requirement is where the final assembly occurred. The new provision requires that eligible vehicles must have their final assembly in the United States.If the final assembly happened in Canada, even if some parts came from the US, the vehicle generally would not qualify. Always verify using the vehicle’s VIN or window sticker.

Q5: I use my car for both work and personal purposes. Can I still claim this?

It depends. You can’t double-dip on the same dollars, but you do have a choice: Option 1 — Keep it simple: Deduct all of the qualifying interest as vehicle loan interest, up to the $10,000 annual cap (subject to the income phase-out). Option 2 — Split it strategically: Deduct the business-use portion of the interest as a business expense, and claim the remaining personal-use portion as vehicle loan interest. The amount of vehicle loan interest available for deduction is reduced dollar-for-dollar by the amount claimed as a business expense.

Q6: What if I have two qualifying car loans? Can I deduct both?

Yes, but there is a combined cap. There is no limit on the number of auto loans that a taxpayer may claim, so long as the vehicles in question meet all prior requirements.However, the total deduction across all qualifying loans is still capped at $10,000 per year per return.

Q7: What form will I get from my lender for the 2026 tax year?

Starting with the 2026 tax year, your lender will have to send you a Form 1098-VLI if you paid at least $600 of qualified interest during the tax year. The form will show the amount of interest paid during the year and other information you may need to claim the car loan interest deduction.You should receive this form by January 31, 2027.

Q8: Is this deduction permanent?

No. The deduction is available annually through 2028.Unless Congress acts to extend or make it permanent, the last tax year you can claim it is 2028 (on a return filed in 2029). You don’t lose the deduction because the loan extends beyond 2028 — you just can’t deduct the interest once the window closes at the end of tax year 2028.

Q9: Does it matter which lender I use — bank, credit union, or dealer financing?

No. You may use any qualified lender, including dealership financing, credit unions, or banks. The key is that your loan includes clear interest terms and is used to finance a new qualifying vehicle.

Q10: What if my state doesn’t conform to this federal deduction? Does it change my federal benefit?

No. Your federal deduction is unaffected by what your state does. If your state has not conformed, your state taxable income remains unchanged by this deduction and you receive no state income tax benefit from the vehicle loan interest.But your federal tax savings still apply regardless of your state’s treatment.

Final Thoughts: Should You Make the Most of This Deduction?

The car loan interest deduction 2026 is a real, meaningful benefit for millions of American families who financed a new, US-assembled vehicle. Because it’s above-the-line, you don’t have to itemize, so the benefit is more broadly available.

For tax year 2026 (return filed in 2027), the big improvement over the prior year is that your lender will issue the official Form 1098-VLI, making the documentation process much cleaner. You simply receive the form, enter the information on Schedule 1-A, attach it to your Form 1040, and you’re done.

The bottom line: if you financed a new, US-assembled personal vehicle after December 31, 2024, and your income falls within the qualifying range, do not leave this deduction on the table. It is one of the clearest, most accessible tax breaks introduced in recent years for everyday working Americans.

As always, review your specific situation with a qualified CPA or enrolled agent before filing. Tax rules can be complex, and your individual circumstances — including income, vehicle usage, and state of residence — can all affect your final result.
