Oregon Bonus Tax Calculator
Data compiled and maintained by Edmond Daher · Updated 2026-06-16
A Oregon bonus feels heavily taxed, but the missing chunk is withholding, not a bonus tax. Oregon adds a flat 8% on top of the 22% federal prepayment and FICA. Run your numbers to see the "now" withholding next to the "at tax time" total, and how much comes back or is still owed. Everything runs in your browser.
Short version: in Oregon, a bonus paid on its own is withheld at the flat federal 22%, 8% for Oregon, and 7.65% FICA. Those are withholding rates, not the tax itself; your bonus settles at your marginal rate on your return — the tool below shows by how much.
Estimate only, not tax advice — terms.
The three cuts on a Oregon bonus: federal, state, and FICA
Federal withholding on a bonus. The IRS default holds back a flat 22% for federal income tax when the bonus is separate from your regular pay (IRS Pub 15). A mandatory 37% hits supplemental pay beyond $1,000,000 a year; neither figure is a special "bonus" rate, both are withholding defaults.
Oregon: a set 8%. Oregon applies one flat supplemental rate — 8% of the bonus — for state withholding (EY 2026 supplemental-rate chart).
FICA is the real tax. Social Security (6.2% to the wage base) and Medicare (1.45%, +0.9% above $200,000) are owed at the same rate they're withheld. That's why the calculator shows the same FICA under "withheld now" and "what it really costs" — there's nothing to refund; only the income-tax portion trues up.

Oregon bonus withholding across three bonus sizes
For a single filer on a $70,000 salary, here's the Oregon withholding at three bonus amounts:
| Bonus | Federal | Oregon | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $400 | $383 | $1,883 | 37.6% |
| $25,000 | $5,500 | $2,000 | $1,913 | $9,413 | 37.6% |
| $100,000 | $22,000 | $8,000 | $7,650 | $37,650 | 37.6% |
Watch the percentage fall once Social Security maxes out; the income-tax slice trues up when you file regardless.
Oregon vs. Washington, California and Idaho: bonus withholding compared
The same $10,000 bonus and $70,000 salary, in Oregon and its neighbors Washington, California and Idaho:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| Oregon | flat 8% | $800 | $3,765 |
| Washington | no state income tax | $0 | $2,965 |
| California | 10.23% / 6.6% | $1,023 | $3,988 |
| Idaho | flat 5.3% | $530 | $3,495 |
Figures are the 22% federal plus state plus FICA for a single filer; the income tax you owe reconciles on your return.
A $6,500 bonus on a $47,000 Oregon salary: withheld vs. actually owed
Picture a Oregon worker on a $47,000 salary handed a $6,500 bonus, paid on its own:
- Withheld now: $1,430 federal (22%) + $520 Oregon + $497 FICA = $2,447 held back, leaving about $4,053 in hand — a 37.6% bite.
- What it actually costs: the true income tax on the bonus is about $1,349 (federal $780 + Oregon $569), plus the same $497 FICA.
- The gap: about $601 of income-tax over-withholding comes back as a refund when you file. The $497 FICA doesn't move — that part is owed no matter what.
Example single-filer numbers from the calculator above; your own refund or bill shifts with your total income and filing status.
The "Oregon bonus tax" myth, and what's really withheld
The flat 22% federal figure (and your state's rate) is a withholding default — not a tax that applies only to bonuses. A bonus is ordinary income, taxed at your true marginal rate when the year runs through the brackets. Most people's real rate is under 22%, so the extra returns; higher earners above 22% owe more. In this page's $6,500 example, about $601 of what's withheld is really over-payment you'd get back. The lone exception is FICA (7.65%), which is a real tax rather than a prepayment.
Oregon bonus tax FAQ
Is there a special bonus tax rate in Oregon?
No. The 22% federal and the state supplemental rate are withholding defaults, not rates that apply only to bonuses. Your real tax is your ordinary marginal rate.
Does a bonus push my Oregon income into a higher bracket?
No. Brackets are marginal — only the dollars above each threshold are taxed higher. A bonus never re-taxes income you already earned.
Does my Oregon bonus ever come back at tax time?
The income-tax part can. If the flat 22% over-withheld relative to your real marginal rate, the excess is refunded; if you're a high earner above 22%, you pay more. FICA is never refunded.
What is the Oregon bonus tax rate in 2026?
Oregon withholds 8% on a separately paid bonus, on top of the flat 22% federal rate (37% above $1,000,000/yr) and 7.65% FICA. That's withholding, not your final tax.
