Quick Answer
Freelancers can deduct auto loan interest proportional to business use starting in 2026. If you use your financed car 70% for business and pay $3,000 in annual interest, you can deduct $2,100. This works alongside mileage deductions but requires detailed records.

How the 2026 auto loan interest deduction works for freelancers
The auto loan interest deduction, added as part of the One Big Beautiful Bill Act, allows self-employed individuals to deduct vehicle loan interest proportional to business use. If you financed a car and use it for business, you can now deduct the business portion of your loan interest payments.
Example: $30,000 car loan with 70% business use
Let's say you're a freelance graphic designer who bought a $30,000 car with a 5-year loan at 7% APR. Your annual interest payment is approximately $2,100. If you use the car 70% for client meetings and business errands:
This deduction reduces your taxable income by $1,470, saving you roughly $225-$515 in taxes depending on your tax bracket (15.3% self-employment tax plus 12-35% income tax).
How it works with other vehicle deductions
You have two main options for vehicle expenses:
Option 1: Standard Mileage Rate
Option 2: Actual Expense Method
Business use percentage calculation
You must track business vs. personal miles to determine your business use percentage:
Record-keeping requirements
To claim the auto loan interest deduction, maintain:
According to IRS Publication 535, inadequate records are the #1 reason vehicle deductions get disallowed during audits.
When this deduction makes sense
The auto loan interest deduction typically benefits freelancers who:
What you should do
Start tracking your business mileage immediately if you haven't already. Use your freelance dashboard to log trips and calculate your business use percentage. Compare the standard mileage method vs. actual expenses (including loan interest) to see which gives you a larger deduction.
Key takeaway: The 2026 auto loan interest deduction can save full-time freelancers $200-$500+ annually, but only if you use the actual expense method and maintain detailed mileage records showing significant business use.

Key Takeaway: Full-time freelancers with financed vehicles can deduct loan interest proportional to business use, potentially saving $200-$500+ annually when using the actual expense method.
Auto loan interest deduction savings by business use percentage
| Business Use % | Annual Interest Paid | Deductible Interest | Estimated Tax Savings |
|---|---|---|---|
| 20% (typical side hustler) | $2,400 | $480 | $180-$220 |
| 50% (moderate freelancer) | $2,400 | $1,200 | $450-$540 |
| 80% (rideshare driver) | $2,400 | $1,920 | $720-$870 |

Auto loan interest deduction for side hustlers
As a side hustler with both W-2 and 1099 income, the auto loan interest deduction can still benefit you, but your business use percentage will likely be lower than full-time freelancers.
Typical side hustler scenario
Most side hustlers use their vehicle:
If you pay $2,400 in annual auto loan interest with 20% business use, you can deduct $480 in interest. Combined with the 15.3% self-employment tax and your marginal tax rate (likely 22% bracket), this saves you roughly $180 per year.
Documentation challenges for side hustlers
Side hustlers face unique record-keeping challenges:
The IRS requires you to allocate mixed-use trips. If you drive from your day job to a client meeting, only the additional miles beyond your normal commute count as business miles.
Standard mileage vs. actual expenses for side hustlers
For most side hustlers with lower business use percentages, the standard mileage rate (67 cents per mile) often provides a larger deduction than actual expenses plus loan interest.
Example comparison:
Only consider the auto loan interest deduction if your actual expenses significantly exceed the mileage rate.
What side hustlers should do
Start with simple mileage tracking for your freelance activities. Calculate both methods at year-end to see which gives you the larger deduction. Most side hustlers benefit more from the standard mileage rate's simplicity.
Key takeaway: Side hustlers with lower business vehicle use (under 40%) typically save more with the standard mileage rate than claiming auto loan interest, but track both options to maximize your deduction.
Key Takeaway: Side hustlers typically save more with the standard mileage rate due to lower business use percentages, but should track both options to maximize deductions.

Auto loan interest for rideshare and delivery drivers
Rideshare and delivery drivers often have the highest business vehicle use among freelancers, making the auto loan interest deduction particularly valuable for those who financed their cars.
High business use percentage advantage
Unlike other freelancers, rideshare drivers typically use their vehicle 70-90% for business:
With such high business use, the actual expense method (including loan interest) often beats the standard mileage rate.
Real driver example
Sarah drives for Uber and DoorDash with these numbers:
This $2,688 deduction saves Sarah approximately $410-$940 in taxes, depending on her total income and tax bracket.
Platform-specific considerations
Uber/Lyft drivers:
Delivery drivers (DoorDash, Grubhub):
Combining with other vehicle expenses
Rideshare drivers using the actual expense method can also deduct:
Record-keeping for drivers
Use driver apps that automatically track mileage, or maintain a simple log with:
Most successful drivers track mileage automatically through apps like MileIQ or Stride.
What rideshare drivers should do
Calculate both the standard mileage deduction and actual expenses (including loan interest) for a few months to see which method saves more. With high business use percentages, actual expenses often win.
Key takeaway: Rideshare and delivery drivers with financed vehicles and 70%+ business use often save significantly more using actual expenses plus loan interest versus the standard mileage rate, potentially saving $500-$1,000+ annually.
Key Takeaway: Rideshare drivers with high business use often save $500-$1,000+ more annually by deducting actual expenses plus loan interest rather than using the standard mileage rate.
