Frequently asked questions

What is Oregon's state income tax rate for self-employed workers?
Oregon uses progressive brackets topping out at 9.9%. Most full-time gig workers sit in the 8.75% bracket on the bulk of their profit.
Do Portland freelancers owe extra local income taxes?
Often yes. The Metro Supportive Housing Services tax (1%) and Multnomah County Preschool for All tax (2.6% and up) apply above income thresholds, and Portland/Multnomah charge a business license tax on net self-employment profit.
When are Oregon estimated tax payments due in 2026?
April 15, June 15, September 15, 2026 and January 15, 2027 — the same dates as federal 1040-ES. Pay through Revenue Online if you expect to owe $1,000 or more of Oregon tax.
How much should an Oregon gig worker save for taxes?
Plan on 30% to 35% of net profit statewide, and closer to 35% to 40% inside Portland once Metro SHS, PFA and the business license tax are included.
Does Oregon allow the standard mileage deduction?
Yes. Oregon starts from federal adjusted gross income, so $0.70 per business mile for 2026 reduces your Oregon and Portland-area bills as well as your federal one.
Do I need a business license to freelance in Oregon?
The state does not require a general license, but Portland and Multnomah County require business tax registration, and Eugene applies its Community Safety payroll tax to self-employment earnings sourced there.
