@SteamTrain ,
Thanks for the excellent summary. That is essentially what I had anticipated but couldn't find it clearly documented anywhere.
Yes it is all W2 income.
As I thought, I really get not benefit for any time working in WA as CO will tax all my income less where I am taxed by another state.
And they are a pretty small company (less than 100 employees) so entirely sure how they run their payroll (internal, via ADP, Gusto or others). So I will press them on setting up my withholding for the correct states/amounts. Probably the best outcome is to withhold CO income tax and then for me to pay OR and get any refund due from CO.
Thanks!
