Home › Portland & Salem › Vancouver vs. Portland Tax
The Columbia River is the most consequential state line in the country for retirees. One side has no income tax; the other has no sales tax. “Best of both worlds” is the pitch — here’s the honest version, including the catches nobody mentions.
Washington has no income tax. Oregon has no sales tax. Both are true, and both are why people obsess over this border. But for a retiree, the decision isn’t a slogan — it’s a calculation that depends on how much income you draw, how much you spend, what you own, and what you’ll leave behind. Five tax categories decide it.
| Tax | Washington (Vancouver / Clark Co.) | Oregon (Portland metro) |
|---|---|---|
| Income tax | None — SS, pension, 401(k)/IRA all untaxed | 4.75%–9.9%; SS exempt, the rest taxable |
| Sales tax | ~8.4% (groceries & meds exempt) | None |
| Property tax | ~0.85–0.95% of market value, annual; no cap | ~0.84–1.08%, capped by Measure 50 |
| Capital gains | 7% only on gains above ~$262K/yr; retirement accounts & real estate exempt | Taxed as ordinary income up to 9.9% |
| Estate tax | Yes, exemption ~$2.2M+ | Yes, exemption just $1M |
The headline for most retirees: if you draw meaningful taxable income from pensions and retirement accounts, Washington’s zero income tax usually wins by a wide margin — often $5,000–$10,000+ a year versus Oregon’s up-to-9.9%. Washington also shelters large estates far better ($2.2M+ vs. Oregon’s $1M) and taxes big capital gains more gently. The Oregon advantages — no sales tax, the Measure 50 property cap — matter most to modest-income, heavy-spending retirees.
Vancouver retirees really do cross the river to make big purchases sales-tax-free in Portland, and for everyday goods, furniture, and electronics that works cleanly. But be honest about the limits: a vehicle you register in Washington owes Washington’s use/sales tax regardless of where you buy it, and the strategy is about spending, not a loophole on titled property. The durable win isn’t the shopping trips — it’s simply living in a no-income-tax state while still having Oregon’s sales-tax-free retail a bridge away.
This one is easy to miss. Oregon’s Measure 50 caps assessed-value growth at 3% a year and lets you inherit an older home’s compressed value, so an established Oregon home can be taxed on far less than it’s worth. Washington reassesses at full market value every year — no cap, no inherited compression. So Oregon’s property-tax structure is genuinely friendlier on an older home, partially offsetting its income tax. Washington does freeze assessed value for senior/disabled owners under an income limit (around $58,000), which is worth claiming if you qualify. The mechanics are on the Clark County property tax guide and the Measure 50 guide.
Washington recently enacted a 9.9% tax on income above $1 million, slated for 2028 and facing legal challenges, and its capital-gains tax (since 2022) is still developing in the courts. For the vast majority of retirees — well under $1M of income and under the ~$262K capital-gains threshold — none of this applies, and the practical answer remains zero income tax. But high-net-worth households should track it.
On the Washington side, the flagship is Fairway Village in Vancouver. On the Oregon side, the closest equivalents are Summerfield and King City in Washington County (which, despite the name, is in Oregon and avoids the Multnomah income tax). We put the two flagships head to head on the Fairway Village vs. Summerfield comparison.
