Oregon income tax goes up to 9.9% at the top bracket. Calculate your combined federal + state effective tax rate for 2026. Formula shown, sources cited — no account required.
Oregon's income tax is one of the steepest in the country, with a top marginal rate of 9.9% that affects a wider range of earners than the label suggests. The bracket structure means median earners at $85,220 typically face effective state rates of 7–8% after standard deductions. At the federal level, the same earner likely falls into the 22% marginal bracket, pushing combined effective rates into the high 20s or low 30s. Oregon's high tax rate pairs with no state sales tax — a notable trade-off that benefits spenders and disadvantages higher earners who do not spend all of their income. Oregon fully taxes all retirement income with no exemptions for Social Security, pensions, or IRAs, which is unusual among states and significantly affects retirement planning. There is no capital gains preference in Oregon — gains are taxed as ordinary income at the full marginal rate. The tax bracket calculator helps you understand where your Oregon income lands across the bracket structure and what strategies might reduce your effective rate.
Oregon's High State Taxes: Federal + State Brackets Explained (2026)
Oregon has a state income tax with a top marginal rate of 9.9%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 40% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Oregon earns $85,220/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 18–21%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Oregon has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
