How to calculate Oregon income tax
Use the calculator above for an instant result. Here is how the calculation works step by step:
- Start with gross income - your total wages or salary before any deductions
- Subtract pre-tax deductions - 401(k) contributions, HSA, health insurance premiums paid pre-tax. This reduces both income tax and FICA
- Apply the federal standard deduction ($15,000 for single in 2026) or your itemized deductions, whichever is larger, to get federal taxable income
- Calculate federal income tax by applying the 2026 bracket rates (10-37%) to your federal taxable income
- Calculate Oregon state income tax - subtract the state standard deduction from AGI, then apply the state brackets
- Add FICA taxes - 6.2% Social Security (capped at $176,100) + 1.45% Medicare (uncapped) + 0.9% additional Medicare above $200,000
- Subtract post-tax deductions - Roth 401(k), union dues, etc.

FICA: Social Security and Medicare (2026)
FICA taxes are separate from income tax and fund Social Security and Medicare. Employees pay:
| Tax | Rate | Wage base |
|---|---|---|
| Social Security | 6.2% | First $176,100 of wages |
| Medicare | 1.45% | All wages (no cap) |
| Additional Medicare surtax | 0.9% | Wages over $200,000 (single) / $250,000 (MFJ) |
Employers match the 6.2% Social Security and 1.45% Medicare contributions, so the total FICA contribution is 15.3% of wages up to the wage base. Self-employed individuals pay the full 15.3% (the "self-employment tax") but can deduct half as a business expense.

What is the difference between marginal and effective tax rate?
Your marginal rate is the rate applied to your last dollar of income - the highest bracket you've reached. Your effective rate is total tax divided by gross income - what you actually pay on average. Your effective rate is always lower than your marginal rate in a progressive tax system, because only income within each bracket is taxed at that rate.
Can I reduce my Oregon income tax?
Yes. Key strategies: maximize pre-tax retirement contributions (401k, IRA), contribute to an HSA if on a high-deductible health plan, and check whether itemizing deductions exceeds your standard deduction. Pre-tax contributions reduce both income tax and FICA taxes. Contributions to a traditional IRA reduce federal taxable income but may not reduce state income tax in all states.
