Work in Oregon, Live in Washington: Taxes Explained

Oregon taxes nonresidents on all income from Oregon sources. When you physically work in Oregon, your wages are Oregon-source income. Washington's lack of income tax is irrelevant — it does not create an exemption from other states' taxes. There is no reciprocity agreement and no credit mechanism because Washington has no tax against which to give you credit.

Do Portland's local taxes apply to Washington commuters?

This is where it gets complicated. Portland's Metro Supportive Housing Services (SHS) tax and Multnomah County Preschool For All (PFA) tax can apply to nonresidents who work within the relevant jurisdictions, not just residents. If you commute from Vancouver, WA to a job in Portland, you may owe these taxes on your Portland-earned income.

The specific rules — including income thresholds, nonresident applicability and filing requirements — are set by the Portland Revenue Division. Check their current guidance for nonresident workers.

Would working remotely from Washington avoid Oregon tax?

If you work remotely from your Washington home for an Oregon employer, the days worked in Washington are not Oregon-source income. Oregon can only tax income from days you physically work in Oregon. Tracking workdays by location is critical — it directly affects how much of your wages Oregon can tax.

This makes remote and hybrid work arrangements particularly valuable for WA residents with OR employers. Every day worked from WA instead of OR reduces your Oregon tax liability with no offsetting increase in WA tax.

How does this compare to the reverse — OR residents working in WA?

The reverse crossing is different: Oregon residents working in WA pay Oregon tax on all income regardless (because OR taxes residents on worldwide income). For them, working in WA provides no tax savings. For WA residents working in OR, the situation is worse — you pay OR tax with no offset. The Portland-Vancouver corridor is unique in that commuters going in either direction pay Oregon tax.

How does day-count apportionment work for WA residents in OR?

Oregon apportions nonresident wages based on the ratio of Oregon workdays to total workdays. If you work 260 days in the year and 200 of those are physically in Oregon, roughly 77% of your wages are OR-source. The remaining 60 days worked from your Washington home are not OR-source and are not taxed by Oregon (or anyone, since WA has no income tax).

This makes hybrid and remote work arrangements especially valuable for WA residents with OR employers. Every day shifted from the Oregon office to your Washington home reduces your taxable income with no offsetting tax increase. Track workdays meticulously — it directly affects your tax bill.

What if my Oregon employer withholds OR tax on all my wages?

Many Oregon employers withhold Oregon tax on the full paycheck without adjusting for WA-based workdays. If this happens:

1. File Oregon Form 40N (nonresident return) at year-end, reporting only OR-source wages based on your actual workday apportionment.
2. Claim a refund for the over-withheld Oregon tax on days you worked in Washington.
3. Ask your employer if they can adjust withholding based on your anticipated work split. Some larger employers with cross-border employees can accommodate this.

What if I moved from Washington to Oregon mid-year?

You file Oregon Form 40P as a part-year resident. During your WA residency period, only OR-source income is taxed by Oregon. After becoming an OR resident, all income is taxed by Oregon regardless of source. Washington has no return to file for either period. Notify your employer at the time of the move so withholding adjusts to full OR resident rates.

Does Oregon have any local income taxes besides Metro and Multnomah?

Oregon itself does not levy a statewide local income tax. However, the Portland Metro SHS tax and Multnomah County PFA tax are relatively new local income taxes that apply to workers and residents in the Portland metro area. Outside of Portland, Oregon does not have significant local income tax obligations. If you work in an Oregon city outside the Metro district (such as Salem, Eugene or Bend), these Portland-area local taxes do not apply.

For WA residents who commute to non-Portland Oregon locations, the tax picture is simpler: Oregon state nonresident tax only, with no local layer. The Portland-area crossing is uniquely complex due to these additional local taxes.
