What is the Oregon state income tax rate?
Oregon has one of the higher state income tax burdens in the US, with rates from 4.75% to 9.9%. Oregon has no sales tax — the income tax is the primary state revenue source. The $125,000 threshold for the 9.9% top rate is lower than many high-tax states.
| Taxable income (single) | Rate |
|---|---|
| $0 – $4,050 | 4.75% |
| $4,050 – $10,200 | 6.75% |
| $10,200 – $125,000 | 8.75% |
| Over $125,000 | 9.9% |
How to reduce your Oregon income tax bill
Oregon's top rate of 9.9% means every dollar you move into a pre-tax account reduces both your federal and Oregon state tax simultaneously. The combined federal + state marginal rate for a middle-income earner in Oregon can easily reach 30–35%, so pre-tax contributions are particularly valuable.
Max your 401k or 403b ($24,500 in 2026)
Traditional 401k contributions reduce your federal and Oregon state taxable income dollar-for-dollar. At the 22% federal bracket plus 9.9% state, each $1,000 contributed saves $319 in current-year taxes. If your employer matches, prioritise contributing at least enough to capture the full match before any other savings goal.
Contribute to an HSA ($4,400 self-only in 2026)
HSA contributions are the only triple-tax-advantaged account in the US code: pre-tax in, tax-free growth, tax-free qualified withdrawals. Available to those enrolled in an eligible high-deductible health plan (HDHP). HSA balances roll over with no use-it-or-lose-it rule and can be invested in index funds for long-term tax-free growth.
Take the federal standard deduction
The 2025 federal standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Most taxpayers (about 90%) are better off taking the standard deduction rather than itemising. Compare your deductible expenses (mortgage interest, state taxes, charitable gifts) to these thresholds before deciding.
Harvest tax losses in taxable investment accounts
Tax-loss harvesting — selling investments that are down to realise a capital loss — can offset capital gains and up to $3,000/year of ordinary income. The wash-sale rule prohibits repurchasing the same or substantially identical security within 30 days, but you can immediately buy a similar (not identical) fund to maintain market exposure while locking in the loss.
Filing your Oregon income tax return: key facts
Federal and Oregon state income tax returns are due on April 15 each year (or the next business day if April 15 falls on a weekend or holiday). An automatic six-month extension can be filed by April 15 — but the extension delays the filing deadline, not the payment deadline. If you expect to owe tax, you must pay an estimate by April 15 to avoid underpayment penalties even if you file later.
Oregon residents file both a federal Form 1040 and a Oregon state income tax return each year. The state return typically starts with federal Adjusted Gross Income (AGI) and applies state-specific additions and subtractions. Free filing options include the IRS Free File program (income under $84,000) and Oregon's own free e-file portal for qualifying residents.
Self-employed workers and independent contractors in Oregon who expect to owe $1,000 or more in federal tax must make quarterly estimated tax payments (due April 15, June 15, September 15, and January 15). Missing these payments triggers an underpayment penalty calculated at the federal short-term rate plus 3%. Use Form 1040-ES to calculate and submit quarterly payments.

Debt Settlement vs Bankruptcy: Which Is Better?
Bankruptcy eliminates eligible debt through a federal court process (3–6 months for Chapter 7); debt settlement negotiates a lump-sum payoff of 25–60 cents on the dollar but takes 2–4 years, does not stop lawsuits, and leaves you with a tax bill. Here is how to choose between them.
