California: California has the highest state income tax rate in the nation at 12.3%, plus a 1% mental health surcharge on income over $1 million.
Washington: Washington has no state income tax on earned income. A 7% capital gains tax applies to long-term gains exceeding $270,000.
Your state income tax is set by where you are a resident, not where your employer is. To stop paying California 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 California 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: California 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.
On a $75,000 single-filer salary, the state income tax difference is about $3,113/year (in your favor). Use the calculator for your exact income.
Once you establish residency in Washington and break California residency, new income is taxed by Washington. California can still tax income earned while you were a resident - file a part-year return for the move year.
