Crossing a state line into or out of Oregon

Oregon taxes its residents on income earned anywhere, and taxes non-residents on work done inside it. Which return you file depends on which direction you commute.

Oregon borders 5 states. They fall into 2 different situations, and which one applies decides whether you file one return or two.

Where you file a nonresident return and claim a credit

Oregon has no agreement with Arizona, California and Idaho. Work in one of these and you file a nonresident return there, report the same income again to Oregon, and claim a credit for what you already paid. The credit is capped at your Oregon liability, so you are not taxed twice, the combined bill lands at roughly the higher of the two rates.

Work state	Its tax	Oregon after credit	Total	Rate that governs
Arizona	$1,750	$3,083	$4,833	Oregon
California	$2,786	$2,047	$4,833	Oregon
Idaho	$3,710	$1,123	$4,833	Oregon

Where the work state takes nothing

Nevada and Washington levy no personal income tax, so there is no return to file there and no credit to claim. But Oregon still taxes the wages as a resident. The catch is withholding: an employer in Nevada or Washington has no state income tax to withhold, so nothing is taken out for Oregon either. The liability is real and nothing is being set aside against it, which usually means Oregon estimated payments.

What Oregon itself takes across a salary range

A single filer, taking the standard deduction. This is the figure every arrangement above is measured against, the tax Oregon charges a resident, whether the work happened inside the state or over a line:

Wages	Oregon tax	Effective rate
$45,000	$2,670	5.93%
$70,000	$4,833	6.90%
$120,000	$9,208	7.67%

Coming the other way: living in a no-income-tax state, working in Oregon

Nevada and Washington border Oregon and levy no personal income tax of their own. A resident of Nevada or Washington who works in Oregon has the simplest arrangement on this page and the least room to improve it: Oregon taxes the wages earned inside it, $4,833 on $70,000, there is no home-state return, and so there is nothing to claim a credit against. Living across a border that charges nothing does not reduce the Oregon bill by a cent.

Reciprocity cannot help either, even where Oregon has agreements: reciprocity shifts the income to the home state's return, and a state with no income tax has no return to shift it to.

What Oregon charges as your home state

Oregon taxes income on 4 graduated brackets for 2026, from 4.75% up to 9.9%. Because wages stacks on top of any other income, a second source can push part of it into the next bracket.

Oregon is also one of five states with no general sales tax, so the total tax picture is lighter than the income tax line alone suggests.

State income tax on wages only, 2026 rates. Not tax advice, what this does and doesn't cover.
