Home / Washington / Oregon
Same $100,000 single salary on opposite banks of the Columbia. Federal ($13,170) and FICA ($7,650) identical — everything else is the state line.
| Washington $100,000 | Oregon $100,000 | |
|---|---|---|
| Federal | $13,170 | $13,170 |
| FICA | $7,650 | $7,650 |
| State | $0 | $8,176 (2026 brackets 4.75–9.9%) |
| Take-home / year | $79,180 | $71,004 |
| Take-home / month | $6,598 | $5,917 |
Oregon's 8.75% middle band does the damage — at $100k most of the salary sits in it, and the 9.9% top rate starts at just $125,000. The classic arbitrage (live in Vancouver WA, work in Portland OR) fails on residency rules: Oregon taxes work performed in Oregon. Washington has no income tax but the nation's highest sales tax pushes the other way at the register.
About $79,180 a year single ($6,598/month) — no state income tax.
About $71,004 a year single ($5,917/month) after ~$8,176 state tax on real 2026 brackets.

Same salary, same federal tax, same FICA — and an $8,176 a year difference. Oregon's income tax is genuinely steep: 4.75% on the first band, 8.75% across the middle, and 9.9% above roughly $125,000 of taxable income. A $100,000 salary sits almost entirely in that middle band.
The popular idea is to live in Vancouver, Washington and work in Portland, Oregon. It does not work the way people hope. Oregon taxes wages for work performed in Oregon regardless of where you sleep, so a Portland-based employee who crosses the river still owes Oregon income tax on those wages — while also paying Washington sales tax at the till. Moving to Washington pays off when the job is in Washington, or when you work remotely for an out-of-state employer that does not withhold Oregon tax.
Over ten years it is roughly $81,760 — a meaningful down payment in most Oregon and Washington markets. It also equals about three years of the average Oregon household's grocery spending. At the till, Washington claws some of it back: the state has no income tax but one of the highest combined sales-tax rates in the country, and vehicle registration fees are notably high. Oregon has no sales tax at all, which makes everyday spending cheaper for everyone regardless of income.
Effective property-tax rates in both states are close to the national middle (roughly 0.8%–1.1% depending on county), so a house at the same price costs roughly the same. Where they diverge is assessment limits: Oregon caps assessed-value growth for long-term owners, Washington is closer to market value with a 1% annual levy limit. Long tenures tend to favour Oregon; recent buyers usually see little difference.
About $79,180 a year single ($6,598/month) — no state income tax on wages.
About $71,004 a year single ($5,917/month) after roughly $8,176 in state income tax on 2026 brackets.
No. Oregon taxes wages for work performed inside Oregon, so a Portland job is taxed by Oregon even if you reside in Washington.
Income-tax-wise yes, by about $8,176 at $100,000. Washington's combined sales tax is among the highest in the country, so heavy spenders narrow the gap.
Effective property-tax rates are similar. Oregon's assessment-growth cap tends to reward long-term owners; recent buyers see little difference.
