How Oregon taxes wages
Oregon income tax in 2026, explained
Oregon is one of only a handful of states with no sales tax, and it makes up the difference with an income tax whose top rate — 9.9% — is among the highest in the country. The rate gets the headlines, but the way Oregon actually computes withholding means most people pay far less than the headlines suggest.
The state uses a four-step formula published by the Department of Revenue (150-206-436): start with your wages, subtract the federal income tax you paid (capped at $8,750), subtract the state standard deduction, and only then apply the bracket table. Finally it subtracts a $263 credit for each allowance you claim. That sequence — federal tax subtracted first — is the single biggest reason Oregon's effective rate undercuts its nominal rate.
The brackets
Oregon tax rates for 2026
| Rate | Single (base wage) | Married (base wage) |
|---|---|---|
| 4.75% | $0 – $4,550 | $0 – $9,100 |
| 6.75% | $4,550 – $11,400 | $9,100 – $22,800 |
| 8.75% | $11,400 – $125,000 | $22,800 – $250,000 |
| 9.9% | Over $125,000 | Over $250,000 |
Notice the shape of the table: the 8.75% bracket is enormous, spanning from roughly $11,400 up to $125,000 of base wage for singles. That means the overwhelming majority of Oregon workers sit in the same marginal bracket — and the 9.9% top rate only ever applies to high earners, and only on the dollars above the threshold, never on their whole income.
The subtraction
Why the federal tax subtraction matters so much
Federal income tax withheld on a $75,000 single paycheck is about $7,670 for 2026. Oregon lets you deduct up to $8,750 of that before it computes state tax, which lowers the base that its brackets apply to by nearly $7,700 — a deduction worth roughly $670 in state tax that most generic calculators simply ignore.
The subtraction phases out above $125,000 for singles and $250,000 for married filers, dropping by $1,750 per $5,000 of wages until it reaches zero. That phase-out acts like a hidden extra tax on income between those ranges — worth planning around if you're negotiating a raise near the cliff. This calculator applies the phase-out automatically.
What you'll owe
Oregon state tax at common salaries
Single filer, one allowance, no pre-tax deductions, outside Portland's local-tax districts. Figures are annual Oregon withholding for 2026:
| Wages | Single | Married / joint | Single effective state rate |
|---|---|---|---|
| $50,000 | $3,204 | $2,809 | 6.4% |
| $75,000 | $5,054 | $4,746 | 6.7% |
| $100,000 | $7,147 | $6,671 | 7.1% |
| $150,000 | $12,805 | $10,949 | 8.5% |
| $200,000 | $17,755 | $15,324 | 8.9% |
| $300,000 | $27,655 | $25,611 | 9.2% |
Across every income level, the effective state rate is well under the 9.9% headline — usually 60% to 90% of it. And the single-vs-married gap is visible everywhere: at $100,000 the married filer pays $476 less because the married standard deduction and wider lower brackets push more income into the lower rates.
The formula step by step
How the calculator reaches your number
- Annualize your pay based on the frequency you choose.
- Compute federal withholding from the 2026 IRS brackets and standard deduction, minus $2,000 for each dependent child.
- Subtract federal tax (capped at $8,750, phased out by income) and the state standard deduction ($2,910 single / $5,820 married) to get your base wage.
- Apply the bracket table to the base wage.
- Subtract $263 per allowance (allowances are zeroed above $100,000 single / $200,000 married).
Pre-tax deductions change the inputs at step 2 and step 3: 401(k) and 403(b) contributions reduce both federal and Oregon taxable wages (but not FICA), while HSA/FSA/insurance premiums reduce all three.
The kicker
Oregon's surplus refund
When Oregon collects more revenue than the state budget forecast, the Oregon Constitution requires the surplus to be returned. The result is the kicker — a credit on your state return (or a direct refund, which triggered the kicker check many Oregonians received). It is applied at filing time, never through withholding, so it won't appear in this calculator. It typically works out to a meaningful percentage of your prior-year liability when it fires.
Single vs married
Married, head of household, and allowances
Your filing status changes three numbers: the state standard deduction, the bracket thresholds, and the phase-out starting points for the federal tax subtraction. Married filing jointly gets the $5,820 standard deduction and double-width brackets; head of household is treated like single for Oregon withholding. The allowance count also matters — each is worth $263 — but the law zeroes them out entirely for high earners, which is why this calculator's Oregon tax jumps at $100,000 single / $200,000 married even though the brackets don't change there.
