About Oregon state taxes (Tax year 2026)
Oregon's 2026 ordinary income-tax rates are 4.75%, 6.75%, 8.75% and 9.9%. Filing status, Oregon deductions, the separate federal-tax subtraction and eligible credits affect the estimate. The calculator identifies its official rate-chart method and the difference between the DOR and LRO single-filer charts.
Oregon has no state or local sales tax. This applies to all purchases made in the state.
Oregon's top rate of 9.9% is far above the national average, but the complete absence of sales tax makes its total tax burden more moderate than the income tax rate alone suggests.

Tax type on this return: Progressive. Top marginal rate: 9.9%. State sales-tax rate: 0%. For the most current contact info, see the Federation of Tax Administrators directory.

Methodology
These pages estimate annual state income tax for the selected 2026 jurisdiction and filing status. The route's coverage panel identifies the supported income basis, deductions, credits and exclusions.
Assumptions
- Enter the income basis and eligible pre-tax deductions requested by the calculator; gross wages, federal AGI and state AGI are not interchangeable.
- Some methods require confirmed state facts or explicit projection assumptions. An unavailable component is not zero tax.
Limitations
- The estimate excludes unmodeled income, adjustments, local taxes and special filing situations. Utah's indexed-credit assumptions remain provisional while final 2026 instructions are pending.
- Annual liability differs from withholding and paycheck take-home. Confirm the current official forms and source versions for a complete return.
