Starting in 2025, taxpayers can finally deduct up to $10,000 per year in interest paid on personal auto loans.

1️⃣ Overview of the 2025 Auto Loan Interest Deduction
This new deduction allows taxpayers to separately claim interest paid on a qualified personal auto loan.
Here are the essential points:
- Maximum annual deduction: $10,000 (interest only, not principal)
- Applies for tax years 2025–2028
- Available whether you claim the standard deduction or itemized deductions
- Subject to a MAGI-based phase-out
- Applies to personal-use vehicles such as cars, SUVs, vans, pickup trucks, and motorcycles
- Loan must be a first-lien, qualified auto loan
In short: if you finance a personal vehicle during 2025–2028, keeping track of your annual interest could produce up to a $10,000 tax deduction.
2️⃣ Annual Limits, Eligible Years, and MAGI Phase-Out
- Eligible years: 2025, 2026, 2027, 2028
- Annual deduction cap: $10,000
- MAGI thresholds:
• Single: phase-out begins above $100,000
• MFJ: phase-out begins above $200,000
Your deduction decreases by $200 for every $1,000 your MAGI exceeds the threshold.
Thresholds:
- Single: over $100,000
- MFJ: over $200,000
So every $1,000 above the limit → $200 deduction reduction.
Example:
If a Single filer has MAGI of $120,000:
→ Exceeds threshold by $20,000
→ $20,000 ÷ 1,000 = 20 increments
→ 20 × $200 = $4,000 reduction
If the original deductible interest was $9,000, the final deduction becomes $5,000.
The deduction can never be reduced below zero.
3️⃣ What Counts as an “Eligible Vehicle”?
A vehicle must satisfy all of the following criteria to qualify for the Auto Loan Interest Deduction:
- Original use must begin with the taxpayer
— Most used vehicles will not qualify because prior owners have already placed them in service. - Manufactured for use on public roads
- Acceptable vehicle types: passenger cars, minivans, vans, SUVs, pickup trucks, motorcycles
- GVWR under 14,000 lbs
- Must meet the U.S. environmental definition of a “motor vehicle”
- Final assembly must occur in the United States
— a critical qualification requirement - Leased vehicles do NOT qualify
— lease payments do not contain deductible interest - Business-use vehicles are excluded
— interest is already deductible under Schedule C/E/F rules
• Use a manufacturer VIN decoder or the NHTSA VIN lookup to confirm the assembly plant.
• Save screenshots or documentation in the client file for potential IRS inquiries.
• Many imported vehicles will automatically fail this requirement.
• The deduction applies only to interest on a loan — not lease payments.
• A lease is legally a rental contract, not a financing arrangement.
• Therefore, no portion of a lease payment can be claimed as “auto loan interest.”
• Business-use vehicle interest is already deductible on Schedule C/E/F.
• The new rule prevents duplicate deductions.
• For mixed-use vehicles, only the personal-use portion may qualify.
• “Original use” means the taxpayer must be the first person to place the vehicle in service.
• Most used cars fail this requirement because prior registration already occurred.
• Exception: new but not titled dealer inventory may qualify even if test-driven.
• Always check Carfax or AutoCheck for prior registration history.
4️⃣ What Interest Qualifies — and What Doesn’t
✅ Qualifying Interest
- Interest paid on or after January 1, 2025
- Interest from a qualified auto loan entered into on or after January 1, 2025
- Loan must be a first-lien secured loan on a qualified vehicle
- Refinanced loans qualify only for the remaining principal of the original qualified loan
❌ Non-Qualifying Interest
- Interest paid to related parties
- Any amount embedded in lease payments
- Interest from loans originated before 2025
- Business-use vehicle interest already deductible elsewhere
5️⃣ Step-by-Step Calculation Examples
• Filing status: Single
• MAGI: $120,000
• Annual auto loan interest: $9,000
Phase-out:
($120,000 − $100,000) ÷ 1,000 × $200 = $4,000 reduction
Final deduction: $5,000
• Filing status: MFJ
• MAGI: $180,000
• Interest paid: $7,500
MAGI is below the $200,000 threshold.
Final deduction: $7,500
6️⃣ EA-Style Practical Tax Tips
• This deduction is separate from the standard/itemized deduction, making it valuable for low- and middle-income taxpayers.
• Maintain copies of the loan agreement, payment history, and annual interest statements.
• Incorrect VIN entry can invalidate the deduction — double-check numbers and letters.
• Auto loans originated in 2024 generally do not qualify.
• Combine this deduction with others introduced in 2025 (overtime deduction, senior deduction, etc.) for strategic tax planning.
