Top drawbacks
- ✕State income tax at 9.9% (top bracket, kicking in at ~$125K) is among the highest in the US. High earners considering Oregon should compare against Washington's 0% and factor $10,000+/year state tax hit.
- ✕Portland has real livability concerns downtown that haven't fully resolved. Outside central downtown, residential neighborhoods are fine, but the downtown office/retail core is struggling.
- ✕PNW cloud cover runs October-April just like Seattle — 150+ cloudy days per year. Seasonal affective disorder is real for transplants from sunny climates.
