Where Washington is gaining from other states
Largest net state-to-state changes by county — same basis as the figures above, top eight only. Each city page adds the in-state picture.
Each bar shows that state's in/out split — rows ranked by total volume. The IRS publishes only each county's largest partner states, so smaller streams are left out and these totals run below the headline figures.
Households arriving in Washington from another state report
$89,952 in average annual income;
those leaving for another state report

Departures out-earn arrivals — Washington is losing its higher earners.
How this works: IRS SOI County-to-County Migration Data, 2022-2023. The IRS compares the address on consecutive tax
returns, so every move here is a real filed household. The headline figures and county lists count moves that
crossed a state line; the five-year chart counts every move, including from abroad. The data publishes annually
with about a two-year lag, misses people who don't file a return, and leaves 24% of moves
unattributed to a specific county, because flows too small to publish are grouped into regional buckets.
39 of Washington's counties have published data.
