Moving from Montana to Washington
Everyone compares rent and groceries. Almost nobody compares the two numbers that actually decide whether a move works: state income tax and property tax. Here is Montana and Washington, side by side.
Moving to Washington costs about
+$750/mo
more than Montana each month, renting
Worth knowing
Washington has no state income tax, and it still costs more
Moving to Washington would save you about $263 a month in state income tax. It also costs about $1,013 a month more in everything else, so you end up roughly $750 a month worse off. No income tax does not mean no taxes.

What the move itself costs
$1,800 to $4,200
From a container you load yourself up to full-service movers.
Shipping one car adds about $450 to $650, against roughly $200 in fuel and lodging to drive it the 2-day trip yourself.
These are statewide figures. Billings is not Montana-average and Seattle is not Washington-average, so a specific city can look nothing like its state. Compare metro areas instead to narrow it to 387 real places, including which side of a state line you would live on.
Run this with your own numbers
Estimates only, not advice. Housing and income figures come from the U.S. Census Bureau's American Community Survey (2024); price levels from the Bureau of Economic Analysis (2024); tax rates are for the 2026 tax year, compiled from state revenue departments and the Tax Foundation. Moving costs are modelled from published ranges rather than quoted. Every figure is a statewide median or average and will not match any particular household.
