Cost of Living in Washington
Washington's cost of living is shaped by a genuinely low overall tax burden for most households (no wage income tax, moderate property tax, and among the cheapest electricity in the country) set against genuinely high housing costs in the Puget Sound corridor and a real, substantial sales-tax bite most movers underestimate.

Learn moreNo wage income tax, real capital gains excise tax, high sales tax -- the true Washington tax picture
Most Washington households pay no state tax on wage income at all. High earners with substantial long-term investment gains should understand the real capital gains excise tax (7% above an annual threshold, 9.9% on gains above $1 million) before assuming otherwise. And every household, regardless of income, pays Washington's genuinely high sales tax -- 6.5% statewide base plus local add-ons pushing many jurisdictions past 10%, including Seattle's 10.55% combined rate as of 2026. This real sales-tax exposure is a meaningful, disclosed cost a bare "no income tax" framing tends to obscure.
Housing is the real, dominant cost divide within Washington
Seattle's housing market is genuinely expensive: Zillow's Home Value Index put the average Seattle home at $865,273 as of May 2026, with single-family homes running $840,000-$870,000. Spokane, by contrast, is genuinely, currently more affordable -- $395,000-$418,900 across the methodologies reviewed for that market, with prices flat to slightly declining rather than appreciating. Tacoma sits between the two ($485,000-$507,000). This spread -- often more than double between Seattle and Spokane for a comparable home -- is the single largest driver of real cost-of-living difference within the state.
Property tax runs genuinely moderate, with a real structural growth cap
Washington's statewide average effective property tax rate runs roughly 0.75% (a real, disclosed 0.73%-0.94% spread across aggregators reviewed), below many states built earlier in this project. Washington law also generally caps most local taxing districts' regular property tax levy growth at 1% per year absent a voter-approved exception (RCW 84.55, rooted in Initiative 747) -- a real structural constraint on the district's total collections, though not a guarantee that any individual property's bill won't rise faster if its assessed value grows faster than the district average.
Electricity is genuinely, substantially cheaper than the national average -- thanks to hydropower
Washington's residential electricity rates run meaningfully below the national average (roughly 34% below per 2026 comparative sources, driven by hydroelectric dams supplying roughly 60% of the state's power, more than any other state, with the Bonneville Power Administration selling wholesale federal hydropower to public utilities at cost). Rates vary by utility -- Seattle City Light runs cheaper than investor-owned Puget Sound Energy, which relies more on natural gas -- and utilities statewide announced 2.5%-12% rate increases for 2026 tied to infrastructure upgrades and data-center demand growth in Eastern Washington, a real, current cost trend worth confirming with your specific utility.
Key takeaways
- Washington's real cost-of-living advantage is no wage income tax and among the cheapest electricity in the country (hydropower-driven) -- offset by a genuinely high sales tax burden most movers underestimate.
- Housing cost is the largest real driver of cost-of-living variation within Washington -- Seattle ($840,000-$870,000+ single-family) runs more than double Spokane ($395,000-$418,900).
- Washington's statewide average effective property tax rate (roughly 0.75%) runs genuinely moderate, reinforced by a real 1%-per-year levy growth cap on most local taxing districts.
- Electricity runs roughly 34% below the national average statewide, though 2026 utility rate increases (2.5%-12%) are a real, current trend to confirm with your specific provider.
