Oregon Tax Brackets Guide – Oregon’s state income tax uses a progressive bracket system with rates ranging from 4.75% to 9.90%. Whether you’re a full-year resident, part-year resident, or planning a move to the Beaver State, understanding the Oregon tax brackets helps you estimate your liability, plan withholdings, and avoid surprises when filing Form OR-40. This guide covers the latest 2026 brackets, how they compare to federal taxes, deductions, credits, and practical filing advice for U.S. taxpayers.
What Are Oregon Tax Brackets?
Oregon imposes a graduated (progressive) individual income tax on taxable income after federal adjustments and state-specific modifications. The state starts with your federal adjusted gross income (AGI), applies additions and subtractions (including a subtraction for federal income taxes paid), then subtracts the standard deduction or itemized deductions to arrive at Oregon taxable income.
The four brackets mean higher-income earners pay a higher marginal rate only on the income falling into each bracket. Oregon adjusts most brackets annually for inflation, though the top bracket is not fully indexed.
2026 Oregon Income Tax Brackets
Here are the official 2026 Oregon income tax brackets for the most common filing statuses. These apply to tax year 2026 (returns filed in 2027). Rates and thresholds are confirmed by the Tax Foundation and align with Oregon Department of Revenue (DOR) guidelines.
Single Filers & Married Filing Separately

Oregon Standard Deduction & Personal Exemption Credit for 2026
Oregon offers its own standard deduction (separate from federal):
- Single / Married Filing Separately: $2,910
- Married Filing Jointly: $5,820
Oregon also provides a nonrefundable personal exemption credit of $256 per taxpayer/dependent (or $512 for a couple). This credit phases out completely if federal AGI exceeds $100,000 (single) or $200,000 (joint).
How Oregon Tax Brackets Work (Marginal vs. Effective Rate)?
Oregon taxes income progressively. Only the income within each bracket is taxed at that rate. Your marginal rate is the rate on your last dollar earned, while your effective rate is usually lower (total tax divided by total income).
Example (Single filer, $80,000 taxable income in 2026):
- First $4,550 → 4.75%
- Next $6,850 ($4,551–$11,400) → 6.75%
- Remaining $68,600 ($11,401–$80,000) → 8.75%
Most Oregon residents fall into the 8.75% or lower brackets. Use the free Oregon Personal Income Tax Calculator on the DOR website for exact figures.
Oregon vs. Federal Income Tax Brackets (2026)
Oregon brackets are independent of federal brackets. Federal rates for 2026 range from 10% to 37% with much higher thresholds (e.g., 24% starts around $105,700 for single filers). Oregon’s top rate of 9.90% kicks in at $125,000 single / $250,000 joint—making the combined federal + state burden significant for higher earners.
Oregon residents also benefit from no state sales tax, which helps offset the income tax load compared to high-sales-tax states.
