How to Claim Mileage on Your 2026 Taxes (Schedule C)

Self-employed drivers claim the mileage deduction on Schedule C, line 9, of their federal tax return. The math is total business miles times 72.5 cents per mile for 2026. The hard part is having the log to back the number up.

Who Can Claim the Mileage Deduction

Self-employed workers, independent contractors, and small-business owners who file Schedule C can claim the mileage deduction. Examples: gig drivers (Uber, Lyft, DoorDash), 1099 sales reps, freelance trades, real-estate agents, owner-operators.

W-2 employees cannot claim the mileage deduction on the federal return. The Tax Cuts and Jobs Act of 2018 suspended the unreimbursed-employee-expense deduction, and the One Big Beautiful Bill made that suspension permanent. If you are a W-2 employee, your remedy is employer reimbursement, which is mandatory in a handful of states.

Step 1: Calculate Your Deduction

Two methods. Pick one for the year. More on choosing in the methods guide.

• Standard mileage rate. Total business miles times 72.5 cents. That is the entire calculation. 12,000 business miles equals an $8,700 deduction.
• Actual expenses. Total your year's gas, oil, insurance, registration, repairs, lease payments or depreciation, then multiply by your business-use percentage (business miles divided by total miles).

Most self-employed drivers use the standard mileage rate because the math is simpler and the recordkeeping burden is much lower. Actual expenses can be larger for high-cost vehicles, especially in the first few years when depreciation is highest.

Step 2: Fill Out Schedule C

Schedule C, Part II "Expenses," has line 9 labeled "Car and truck expenses." That is where the mileage deduction goes.

Schedule C, Part IV asks four questions about your vehicle: when you placed it in service, total business miles, total commuting miles (which is zero for most self-employed drivers because there is no fixed office), and total other miles. You need these numbers ready.

If you used the actual-expense method, you also fill out Form 4562 for depreciation. Standard-rate filers skip 4562.

Step 3: The Self-Employment Tax Win

The mileage deduction is unusual because it reduces both income tax AND self-employment tax. Self-employed workers pay 15.3% in self-employment tax (Social Security plus Medicare) on top of income tax. A $1,000 mileage deduction saves you whatever your marginal income tax bracket is, plus 15.3 cents on the dollar in SE tax.

For a driver in the 22% bracket, a $1,000 deduction saves $220 in income tax plus $153 in SE tax: $373 total. That is more than 1.5x what the same deduction is worth to a W-2 employee even when they could claim it.

Step 4: State Returns

Most states use your federal adjusted gross income as the starting point for state tax. That means your federal mileage deduction reduces your state tax automatically, with no extra form. Forty-one states have an income tax. Nine do not, and Schedule C filers in those states benefit only at the federal level. See your state's breakdown.

Step 5: Keep Your Log

You do not file your mileage log with your tax return. You keep it in case the IRS asks. Keep it for at least seven years. See what the IRS requires in a log.

Common Mistakes

• Claiming commuting miles as business miles. Driving from home to a regular workplace is commuting, not business. Driving from home to a temporary job site can be business. The distinction matters in an audit.
• Mixing methods within the year. You pick one method per vehicle per year. You can switch in a future year, but only if you used the standard rate the first year.
• Switching to actual expenses too late. If you used actual expenses the first year you placed a vehicle in service, you cannot switch to standard for that vehicle. Pick carefully in year one.
• Forgetting to track expenses if you use actual. The actual method requires documentation for every gas receipt, repair, and insurance payment. The recordkeeping is much heavier than the standard method.

FAQ

Where on Schedule C does mileage go?

Part II, line 9, "Car and truck expenses." Vehicle details (date placed in service, miles by category) go in Part IV.

Do I file my mileage log with my tax return?

No. You file Schedule C with the deduction amount. The log stays with your records in case of audit.

Can I claim mileage if I take the standard deduction?

Yes. Schedule C deductions reduce business income before AGI is calculated, so they are independent of whether you itemize or take the standard deduction on your personal return.

What if I drove for two different gigs?

If both are self-employment income reported on the same Schedule C (e.g., Uber and Lyft are both ride-hailing), combine miles. If they are separate businesses on separate Schedule Cs (e.g., Uber driving plus a freelance writing business), allocate miles to whichever business they served.

Do I need to file estimated quarterly taxes?

If you expect to owe more than $1,000 in federal tax for the year, the IRS expects quarterly estimated payments. The mileage deduction reduces the income you base estimates on. Many self-employed drivers file Form 1040-ES four times a year.
