Home › Portland & Salem › Moving from Idaho
If you’re leaving Idaho for the Willamette Valley, be honest with yourself about one thing: on retirement-income taxes, Idaho is hard to beat, and Oregon is not an upgrade. The reasons to move are real — they’re just not about income tax.
Idaho runs a flat income tax of about 5.7% — well below Oregon’s 9.9% top rate — and, crucially, offers a large retirement-income deduction for residents 65+ (recently up to about $47,935 single / $95,870 married) that can zero out state tax on moderate pension and retirement-account income. Social Security is exempt, property taxes are among the lowest in the country (~0.5%), and there’s no estate tax. For a retiree with moderate withdrawals, Idaho can be effectively a no-income-tax state.
Don’t fool yourself on income tax. Moving from Idaho to Oregon means trading a low flat rate with a generous senior deduction for one of the highest top rates in the country — and Oregon has no equivalent broad senior retirement deduction. If your retirement income is substantial, your state income-tax bill will very likely go up in Oregon. This is the opposite of a California or New York move. Go in clear-eyed.
| Factor | Idaho | Oregon |
|---|---|---|
| Income tax | ~5.7% flat | 4.75%–9.9% graduated |
| Senior retirement deduction | Large (65+, up to ~$48K/$96K) | Modest credit/subtraction only |
| Social Security | Exempt | Exempt |
| State sales tax | 6% (groceries partly offset by credit) | None |
| Property tax (effective) | ~0.5% (very low) | ~0.84%–1.05%, capped by Measure 50 |
| Estate tax | None | $1M exemption |
Oregon’s lack of a sales tax is a genuine, everyday saving Idaho can’t match — meaningful if you spend heavily, especially on vehicles, appliances, and big-ticket items. For a high-spending retiree it can offset a chunk of the income-tax difference.
The Willamette Valley offers a milder, greener climate than much of Idaho, with the Oregon Coast about an hour from Salem and wine country at the doorstep. For buyers who want water, forests, and fewer hard winters, that’s the draw — not the tax code.
If Boise’s run-up has priced you out of the home you want, the Salem corridor — Woodburn in particular — can offer single-level living and bundled golf at prices that compete well, while putting you near Portland’s airport and medical centers.
Favor communities outside the Portland local-tax zones (every community we cover except Summerplace qualifies), consider the timing of large retirement-account withdrawals, and look at older resales to inherit a compressed Measure 50 assessed value. Start with the Oregon retirement tax guide and the Measure 50 guide.
