How the mileage deduction works in Oregon for 2026
The mileage deduction is taken on Schedule C under IRC §162. For 2026, the IRS standard rate is 72.5 cents per mile (IRS Notice 2026-10). Alternatively, you can deduct the business-use percentage of your actual vehicle costs.
Federal savings cascade: The deduction reduces Schedule C net profit, which lowers SE tax (15.3% on 92.35% of net profit). The reduced SE tax also lowers the deductible half of SE tax, which further reduces federal AGI and federal income tax.
Oregon taxes federal AGI minus the Oregon standard deduction. The mileage deduction reduces your Schedule C net profit, which reduces federal AGI and therefore reduces Oregon taxable income at your marginal Oregon rate.
Which method saves more?
The standard method wins when 72.5 cents per mile exceeds your actual cost per mile (common with fuel-efficient or low-cost vehicles and high business mileage). The actual method wins when your real vehicle costs per business mile exceed 72.5 cents (common with trucks, luxury vehicles, or high-cost leases with relatively few business miles).
Recordkeeping requirement
The IRS requires a contemporaneous mileage log with the date, destination, business purpose, and miles for each trip. Commuting miles from home to a regular office are not deductible. Keep receipts for all vehicle costs if you use the actual method.

Frequently asked questions
What is the mileage deduction for freelancers?+
Freelancers and self-employed people can deduct business driving costs on Schedule C under IRC §162. The 2026 IRS standard mileage rate is 72.5 cents per mile (IRS Notice 2026-10). Alternatively, you can deduct a business-use percentage of your actual vehicle costs. The deduction reduces your Schedule C net profit, which lowers SE tax, federal income tax, and most state income taxes.
Does the mileage deduction reduce self-employment tax?+
Yes. The mileage deduction is a Schedule C deduction, which reduces net profit before SE tax is calculated. SE tax is 15.3% on 92.35% of net profit. A $7,250 deduction (10,000 miles at the standard rate) saves roughly $1,024 in SE tax in addition to federal and state income tax savings.
What records are required for the mileage deduction?+
The IRS requires a contemporaneous mileage log recording the date, destination, business purpose, and miles for each business trip. Commuting miles to a regular office are not deductible. Apps, spreadsheets, or a paper logbook all satisfy the requirement as long as they are maintained at or near the time of each trip.
Does Oregon follow the federal mileage deduction?+
Yes. Oregon conforms to federal Schedule C treatment. Oregon has graduated income tax rates from 4.75% to 9.9%, with a top rate of 9.9% above $125,000 single ($250,000 MFJ) for 2026. Oregon taxable income is federal AGI minus the Oregon standard deduction ($2,420 single / $4,840 MFJ for 2026). The mileage deduction reduces Oregon taxable income at your marginal Oregon rate.
What Oregon income tax rate applies to mileage savings?+
Oregon's four brackets range from 4.75% to 9.9%. For 2026, the 8.75% rate applies to income between $18,401 and $125,000 for single filers. Most freelancers earning $60,000 to $125,000 pay a marginal Oregon rate of 8.75%, making Oregon one of the higher-tax states where mileage deductions generate meaningful state savings.
