How Oregon State Income Tax Works
Oregon uses a progressive tax system with 4 tax brackets. As your income increases, different portions are taxed at higher rates. Only the income within each bracket is taxed at that bracket's rate.
Tips for Oregon Taxpayers

- Consider itemizing deductions if they exceed the standard deduction
- Make estimated quarterly payments if you're self-employed or have significant investment income
- Keep detailed records of all income, deductions, and tax payments
- Consider contributions to tax-advantaged accounts like 401(k)s and IRAs to reduce taxable income
