Oregon Income Tax: Graduated Brackets Up to 9.9%
Oregon uses a progressive income tax system with 4 brackets. Rates range from 4.75% to 9.9%, with higher income taxed at higher rates. Oregon has no sales tax, so income tax is the primary revenue source. The top rate of 9.9% is among the highest in the US.
Like federal taxes, Oregon's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), Oregon residents can face a total marginal rate of up to 46.9% on their highest dollars of income.
Oregon Tax Brackets for 2026 (Single Filer)
The Oregon income tax brackets for single filers are:
- 4.75% on income from $0 to $4,050
- 6.75% on income from $4,050 to $10,200
- 8.75% on income from $10,200 to $125,000
- 9.9% on income over $125,000
Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your Oregon Tax
Maximize pre-tax retirement contributions to reduce both federal and Oregon taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). If Oregon conforms to federal deductions, your standard deduction and itemized expenses also reduce your state tax liability.
