Oregon taxes individual income with four progressive brackets from 4.75% up to 9.9% — and has no general sales tax, which is why its income rates run high. Portland-area residents may also owe the Metro Preschool For All tax. This free calculator estimates both.
How it works
Oregon income tax is computed in steps:
- Start from your Oregon taxable income (Oregon begins from federal taxable income with state adjustments).
- Apply the four brackets — 4.75%, 6.75%, 8.75%, and 9.9% — where each rate hits only the income inside its band.
- If you live in Multnomah County (Portland), add the Metro PFA tax:
1%on income above$125,000single or$200,000joint.
The total is your combined Oregon-area income tax. Your effective rate sits below the 9.9% marginal rate because only the top slice is taxed at the highest rate.
Example
A single Portland resident with $200,000 taxable income pays Oregon state tax across all four brackets (roughly $17,800), plus the Metro PFA tax of 1% × ($200,000 − $125,000) = $750, for about $18,550 total — an effective rate near 9.3%.
Notes
This estimate covers Oregon state income tax and the optional Metro PFA surtax only — not federal tax, FICA, the Multnomah County personal income tax (SHS), or local credits. Bracket thresholds are indexed annually, so use the figures for the year you are filing.
