Your state income tax is set by where you are a resident, not where your employer is. To stop paying Oregon tax you must genuinely establish residency in Washington - register to vote, change your driver's license and car registration, move your primary home, and spend more than half the year there. High-tax states like Oregon audit departing high earners, so keep records of your move date.
In the year you move you typically file a part-year resident return in both states: Oregon taxes income earned while you lived there, Washington taxes the rest. Remote workers should note that a handful of states tax income sourced to the state even for non-residents - check before assuming a clean break.
Washington has NO state income tax - one of nine states with no wage income tax.
