Quick Answer: Is Auto Loan Interest Tax Deductible in 2026?
Yes. The One Big Beautiful Bill Act (P.L. 119-21) created a new federal above-the-line deduction for interest paid on qualifying new-vehicle loans:
- Annual cap: Up to $10,000 in qualified vehicle loan interest per year
- Tax years: 2025 through 2028 (loans originated after December 31, 2024)
- Vehicle: Must be new, assembled in the U.S., and under 14,000 lbs GVWR
- Income limits: Phases out above $100,000 MAGI ($200,000 MFJ)
Because this is a deduction (not a credit), it reduces your taxable income rather than your tax bill directly. Your actual savings equal the deducted amount times your marginal tax rate. Most buyers will save under $750 in the first year.

Key Takeaways
- Deduction, not a credit. This reduces your taxable income, not your tax bill dollar-for-dollar. Your actual savings depend on your marginal federal tax bracket.
- Up to $10,000 per year. The annual cap on deductible vehicle loan interest is $10,000 for tax years 2025 through 2028, regardless of filing status.
- New, U.S.-assembled vehicles only. The vehicle must be new (original use starts with you), assembled in the U.S., and weigh under 14,000 pounds GVWR. Used cars, leases, and imports assembled abroad are excluded.
- Income phaseout is steep. The deduction starts phasing out at $100,000 MAGI ($200,000 MFJ) and disappears entirely at $150,000 ($250,000 MFJ). You lose $200 of the cap for every $1,000 over the threshold.
- Available without itemizing. It's an above-the-line deduction, so you can claim it alongside the standard deduction on the new Schedule 1-A.
- Replaces the EV credit as the main vehicle tax break. The $7,500 EV tax credit (Sec. 30D) ended for vehicles purchased after September 30, 2025. The auto loan interest deduction is now the primary federal tax benefit for car buyers.
What Is the Auto Loan Interest Deduction?
Before the One Big Beautiful Bill Act, interest on a personal car loan was classified as nondeductible personal interest under IRC Section 163(h). That changed on July 4, 2025.
Section 70203 of P.L. 119-21 amended the tax code to exclude "qualified passenger vehicle loan interest" from the definition of nondeductible personal interest. The result: interest you pay on a qualifying auto loan now reduces your federal taxable income.
Key characteristics
- Above-the-line deduction: Available whether you take the standard deduction or itemize. You do not need to file Schedule A.
- Annual cap: $10,000 per year, regardless of filing status.
- Temporary: Effective for tax years 2025 through 2028 only, for loans originated after December 31, 2024.
- Claimed on Schedule 1-A: Part IV of the new Schedule 1-A (Additional Deductions), flowing to Form 1040 line 13b.
Deduction vs. credit: why the distinction matters
A deduction reduces your taxable income. A credit reduces your tax bill dollar-for-dollar. The auto loan interest provision is a deduction, which means your actual federal tax savings equal the deduction amount multiplied by your marginal tax rate.
If you deduct $3,000 in car loan interest and you are in the 22% bracket, your savings are approximately $660, not $3,000. Worth keeping in mind, since headlines promising "no tax on car loans" can create unrealistic expectations about how much you will actually save.
Who Qualifies: Vehicle, Loan, and Income Requirements
You need to clear three hurdles: the vehicle itself, the loan terms, and your income level.
Vehicle requirements (all must be met)
- New vehicle only: Original use must commence with you. Used cars do not qualify.
- Type: Car, minivan, van, SUV, pickup truck, or motorcycle.
- Weight: Gross vehicle weight rating (GVWR) under 14,000 pounds.
- Final assembly in the United States. Many foreign-brand vehicles qualify if they are assembled in U.S. plants (for example, Toyota Camry from the Kentucky plant or BMW X5 from South Carolina).
- Personal use: The vehicle must be for personal, non-commercial use.
- No salvage-title or scrap vehicles.
How to check if your vehicle was assembled in the U.S.
Check the dealer window sticker (Monroney label), use the NHTSA VIN Decoder at nhtsa.gov/vin-decoder, or look at the first characters of the VIN. VINs starting with 1, 4, or 5 indicate U.S. manufacturing. You will need the VIN on your tax return.
Loan requirements
- Originated after December 31, 2024. Loans taken out before 2025 do not qualify, even if you are still making payments.
- Secured by a first lien on the vehicle.
- Not a lease. Lease financing is explicitly excluded. Only purchase loans qualify.
- Not from a related party. Loans from family members or related entities under IRC Sections 267(b) or 707(b)(1) do not qualify.
Income limits (MAGI phaseout)
The deduction phases out based on your modified adjusted gross income (MAGI):
- Single: Phaseout begins at $100,000 MAGI, fully eliminated at $150,000
- Married filing jointly: Phaseout begins at $200,000 MAGI, fully eliminated at $250,000
The reduction formula: the $10,000 cap is reduced by $200 for every $1,000 (or portion thereof) of MAGI above the threshold.
Phaseout math, step by step
Suppose you are a single filer with $120,000 in MAGI:
- Amount over the $100,000 threshold: $20,000
- Number of $1,000 increments: 20
- Reduction: 20 x $200 = $4,000
- Reduced cap: $10,000 - $4,000 = $6,000
If your qualifying interest for the year is $4,200, you deduct the full $4,200 (it falls below the $6,000 reduced cap). If your qualifying interest is $8,000, you deduct only $6,000.
At $150,000 MAGI, the reduction reaches $10,000 (50 increments x $200), and the deduction is fully eliminated.
How Much Will You Actually Save?
Your federal tax savings come down to two things: how much qualifying interest you can deduct and what tax bracket you are in.
Federal tax savings = Deductible interest x Marginal tax rate
Quick savings reference
| Interest Deducted | 10% Bracket | 12% Bracket | 22% Bracket | 24% Bracket |
|---|---|---|---|---|
| $2,000 | $200 | $240 | $440 | $480 |
| $3,500 | $350 | $420 | $770 | $840 |
| $5,000 | $500 | $600 | $1,100 | $1,200 |
| $10,000 (max) | $1,000 | $1,200 | $2,200 | $2,400 |
According to CNBC analysis, typical first-year savings are under $750 for most buyers. Average new car loan rates sit around 7% for a 60-month term, and most loan balances simply do not generate enough interest to hit the $10,000 cap.
The savings compound over time
Interest payments shrink as you pay down the loan, but the deduction is available each tax year through 2028. Someone who finances a vehicle in 2025 could claim it for up to four tax years, adding up to a few thousand dollars in total savings.
How this compares to the old EV credit
The $7,500 EV tax credit (IRC Sec. 30D) was a credit that reduced your tax bill dollar-for-dollar. It was terminated for vehicles purchased after September 30, 2025. The auto loan interest deduction is a deduction, so the per-dollar benefit is smaller. For someone in the 22% bracket, even the maximum $10,000 deduction saves only $2,200, versus the full $7,500 the credit provided.
On the other hand, the auto loan interest deduction covers a much wider range of vehicles (not just EVs), so more buyers can actually use it. An estimated 4 million car owners may benefit from the deduction, according to CBS News reporting.
How to Claim It on Your Tax Return
You will need a new form from your lender and a new section on your tax return.
Step 1: Get your Form 1098-VLI
Starting with tax year 2026, lenders must send you Form 1098-VLI by January 31 if you paid $600 or more in qualified vehicle loan interest during the year. The form shows:
- Total interest paid during the tax year
- Outstanding principal balance
- Loan origination date
- Vehicle year, make, model, and VIN
For TY 2025 filers: Lenders were not required to send Form 1098-VLI for the 2025 tax year. Use your year-end loan statement or add up interest from your monthly statements. Contact your lender's customer service line if you need a year-end summary. Keep this documentation as backup.
Step 2: Complete Schedule 1-A, Part IV
Schedule 1-A is the new form the IRS created for all four temporary OBBBA deductions (tips, overtime, car loan interest, and seniors). Part IV is specifically for the auto loan interest deduction. You will:
- Enter the total qualifying interest paid (from Form 1098-VLI or your own records)
- Apply the $10,000 cap if your interest exceeds it
- Calculate the MAGI phaseout reduction, if applicable
- Enter your vehicle's VIN (required to claim the deduction)
The resulting deduction amount flows to Form 1040, line 13b.
Step 3: Consider adjusting your W-4
You do not have to wait until filing season to see the benefit. If you know you will qualify, update your W-4 using Worksheet 4(b) to reduce federal withholding throughout the year. That puts more money in each paycheck instead of making you wait for a bigger refund.
Tax software support
All major tax software providers (TurboTax, H&R Block, FreeTaxUSA, and others) support Schedule 1-A for the 2026 filing season. The software will walk you through eligibility questions, import your Form 1098-VLI if available, and calculate the phaseout automatically.
Edge Cases: Refinancing, Business Use, and What Does Not Qualify
A few common situations have specific rules worth knowing about.
Refinancing
If you refinance a qualifying auto loan, interest on the new loan remains deductible, but only up to the outstanding principal balance at the time of refinancing. The new loan must also be secured by a first lien on the same vehicle. If you do a cash-out refinance for more than the remaining balance, interest on the extra amount does not qualify.
Business-use vehicles
The OBBBA deduction is for personal-use vehicles only. Self-employed individuals and business owners who use a vehicle for business can already deduct vehicle costs through Schedule C (actual expenses or standard mileage rate). You cannot claim both the OBBBA personal deduction and a business deduction on the same vehicle.
EVs and the deduction
Electric vehicles assembled in the United States do qualify for the auto loan interest deduction. However, the $7,500 EV tax credit under IRC Sec. 30D was terminated for vehicles purchased after September 30, 2025. If you bought an EV before that date and claimed the credit, you cannot also claim the loan interest deduction for the same loan unless the loan was originated after December 31, 2024.
For anyone buying an EV after the credit sunset, the auto loan interest deduction is the main federal tax benefit left for vehicle purchases.
What does NOT qualify
- Used cars: Original use must commence with you. Certified pre-owned vehicles are still used vehicles.
- Leased vehicles: Lease payments are not loan interest. Only purchase loans qualify.
- Vehicles assembled outside the U.S.: Even if the brand is American, the specific vehicle must be assembled domestically. Check the VIN or window sticker.
- Fleet purchases: Vehicles acquired for commercial fleet use are excluded.
- Salvage-title or scrap/parts vehicles.
- Loans from related parties: Family loans or loans from related entities under IRC Sec. 267(b) or 707(b)(1).
- Loans originated before January 1, 2025.

Common questions about the auto loan interest tax deduction for 2026.
Auto Loan Interest Deduction: Savings Examples
These examples use 2026 tax rates and typical auto loan terms. Your numbers will differ based on your full tax situation. Use the Tax Calculator US app to calculate your specific federal tax impact.
A single filer in Georgia earning $65,000 finances a $30,000 new sedan at 7.0% for 60 months.
- First-year interest paid: ~$1,950
- MAGI: $65,000 (below the $100,000 phaseout threshold)
- Deduction claimed: $1,950 (full amount, under the $10,000 cap)
- Marginal tax bracket: 22%
- Federal tax savings: $1,950 x 22% = ~$429
No phaseout applies, so the full interest amount is deductible. Georgia state taxes are unaffected because most states have not adopted this deduction.
A married couple filing jointly in Texas with $140,000 combined income finances a $45,000 new SUV at 8.5% for 72 months.
- First-year interest paid: ~$3,600
- MAGI: $140,000 (below the $200,000 MFJ phaseout threshold)
- Deduction claimed: $3,600 (full amount)
- Marginal tax bracket: 22%
- Federal tax savings: $3,600 x 22% = ~$792
No phaseout applies. Texas has no state income tax, so this is purely a federal benefit.
A single filer earning $120,000 finances a $48,000 new truck at 9.5% for 72 months.
- First-year interest paid: ~$4,200
- MAGI: $120,000 ($20,000 over the $100,000 threshold)
- Phaseout calculation: 20 increments x $200 = $4,000 reduction
- Reduced cap: $10,000 - $4,000 = $6,000
- Deduction claimed: $4,200 (under the $6,000 reduced cap)
- Marginal tax bracket: 24%
- Federal tax savings: $4,200 x 24% = ~$1,008
Even though the phaseout cuts the cap, this buyer's interest falls below it, so the full $4,200 is deductible. At $140,000 MAGI, the cap would drop to just $2,000.
A single filer earning $80,000 finances a $60,000 new vehicle at 10% for 60 months.
- First-year interest paid: ~$5,700
- MAGI: $80,000 (well below the $100,000 threshold)
- Deduction claimed: $5,700 (full amount, under the $10,000 cap)
- Marginal tax bracket: 22%
- Federal tax savings: $5,700 x 22% = ~$1,254
This is near the ceiling for a typical buyer. Hitting the full $10,000 cap would require a very large loan balance or a very high interest rate. Over three more years of deductions (through TY 2028), total savings could reach several thousand dollars.
Frequently Asked Questions
Tips for Maximizing Your Auto Loan Interest Deduction
- Verify U.S. assembly before you buy. Use the NHTSA VIN Decoder or check the window sticker before finalizing your purchase. Some models from the same manufacturer are assembled in different countries depending on the trim level or production year. Checking this upfront avoids a surprise at tax time.
- Keep your loan documents and interest statements. For TY 2025, your lender is not required to send Form 1098-VLI. Save your monthly statements or request a year-end interest summary from your lender. For TY 2026 and later, verify that your Form 1098-VLI matches your records.
- Check whether refinancing makes sense for the deduction. If you refinance, only interest on the outstanding balance at refinancing time qualifies. Avoid cash-out refinancing if you want to maximize the deductible amount. The new loan must maintain a first lien on the same vehicle.
- Adjust your W-4 to benefit now instead of waiting. Use W-4 Worksheet 4(b) to account for the expected deduction. This lowers your federal withholding throughout the year, putting more in each paycheck rather than making you wait for a bigger refund.
- Do not confuse this with the old EV credit. The $7,500 EV tax credit ended for purchases after September 30, 2025. The auto loan interest deduction has a smaller impact (it reduces taxable income, not your tax bill directly) but covers a wider range of vehicles.
- Use the Tax Calculator US app to model your savings. Enter your income and estimated loan interest to see how the deduction affects your federal tax before you file. That way you can decide whether adjusting your W-4 is worth it.
