Moving from California to Washington with RSUs

Washington has no state income tax on wages, but California may still tax income earned while you were a resident.

State sourcing rules may depend on facts and timing

Which state taxes RSU income depends on residency, work location, grant terms, and vest date, not just where you live on December 31. Day-count splits and flat-rate estimates on this site are planning tools only, not legal sourcing determinations.

In plain terms

Washington does not impose a state income tax on wages, so vests you earn as a Washington resident generally are not taxed by Washington. The harder question is what California may still tax, income connected to your California work or residency can remain California-taxable even after you move. That depends on the facts, not just your move date.

How the tax works

Washington has no broad state income tax on wages, so the destination side is usually simple.

California can tax compensation tied to services performed there or to your time as a California resident, including some equity that was earned while you were in the state.

How a specific is sourced between states depends on grant, , and work timing, plus California's own sourcing rules.

Employer payroll may not switch states cleanly on your move date, so can lag reality.

What to check on your end

  • Your official move date and residency change documentation.
  • Which vests occurred while you were a California resident vs. after.
  • How your employer is reporting state wages before and after the move.
  • Whether a part-year California return is appropriate for your situation.
  • California's published guidance or a tax professional for how your equity is sourced.

Common mistake

Assuming the move date wipes out California exposure entirely. Moving to a no-tax state stops new Washington tax, but it does not automatically erase California's claim on income connected to your time or work there.

Example scenario (hypothetical)

Illustration only, not your tax situation.

Example: Sam moves to Washington in July. A in March (as a California resident) is generally California-connected. A in October may be Washington-side for residency, but how earlier-earned equity is sourced still depends on California's rules and the facts.

When a CPA is worth it

  • You vested both before and after the move.
  • You kept working for the same employer remotely.
  • You are unsure whether a part-year California return applies.
  • Your equity was granted in California but vests after you leave.
