Oregon taxes self-employment profit as ordinary income. Oregon has four brackets from 4.75% to 9.9%. The 8.75% and 9.9% breakpoints sit at $125,000 (single) and $250,000 (married), so most middle earners top out at 8.75%. Oregon has no sales tax.
The Portland area adds its own local income taxes on top of the state tax: Multnomah County (Preschool for All) and Metro (Supportive Housing Services), which are not included here.
Note on 2026 figures: Oregon rates and the $125,000/$250,000 breakpoints are fixed, but the Department of Revenue indexes the two lowest bracket thresholds and the standard deduction each year and had not posted 2026 charts at build. The latest official (2025) figures are shown and will be updated when 2026 charts are released.
