The Vancouver-to-Portland move is classic — but crossing the river flips your tax situation in a way that surprises a lot of Washington retirees. Here's the honest math.
Washington and Oregon are tax mirror images. Washington has no state income tax but a sales tax (~6.5%–10%+ with local add-ons). Oregon has no sales tax but a state income tax of 4.75%–9.9% that applies to retirement withdrawals. Many Washington retirees living off a 401(k) assume Oregon will be cheaper because of "no sales tax" — and then discover Oregon taxes the withdrawals they've never paid state income tax on before. It can be a real shock.
You likely win in Oregon if: you live mostly on Social Security (exempt in both states) and Roth withdrawals (untaxed), and you spend enough that escaping Washington's sales tax matters. No income tax on your draw, no sales tax on your spending.
You may pay more in Oregon if: you draw heavily from a traditional 401(k), IRA, or pension. Those become Oregon-taxable income you never paid in Washington — and the sales-tax savings often don't fully offset a 8.75%–9.9% income-tax bite.
This is income tax Washington never charged you. Married filing jointly, standard deduction applied:
| Annual withdrawal (401k / IRA / pension) | Oregon income tax / yr | Monthly equivalent |
|---|---|---|
| $40,000 | $2,386 | $199/mo |
| $60,000 | $4,136 | $345/mo |
| $80,000 | $5,886 | $490/mo |
| $100,000 | $7,636 | $636/mo |
Married filing jointly, 2025 standard deduction applied; the $8,500 federal tax subtraction is not modeled and would reduce these figures. Social Security and qualified Roth withdrawals are exempt. In Multnomah County, add local surtaxes above $125K single / $200K joint.
If you settle in Multnomah County (e.g., Summerplace), add the local surtaxes for higher incomes — the Metro 1% and Multnomah Preschool-for-All 1.5%–3% above $125K single / $200K joint. Salem (Marion/Polk) communities avoid those entirely, which is one reason tax-sensitive Washington retirees often look south to Salem rather than into Portland.
If you want to stay near the river and the city, Summerplace (NE Portland) or the Westside communities (Summerfield in Tigard, Claremont in NW Portland) keep you close to what drew you to the area. If the tax math pushes you to minimize income-tax exposure, Salem's communities — Woodburn, Salemtowne, Ceres Gleann, and the affordable Salem land-lease parks — sit outside the Portland local surtaxes and carry lower property-tax dollar bills. And don't overlook the estate tax: Oregon's $1M exemption is far lower than you may be used to, so bring significant assets into your planning conversation.
