However, Washington employees pay two mandatory payroll taxes: the WA Cares Fund (0.58%) for long-term care insurance and Paid Family & Medical Leave (0.54%). These add roughly 1.1% in state-level payroll deductions.

Plus Washington has $0 income tax while California charges up to 13.3%.

Why are utilities so cheap in Washington?

Washington's utility index is 83, meaning 17% below the national average. This is primarily due to the Columbia River hydropower system — the largest hydroelectric system in the US. The Grand Coulee Dam and over 30 other dams generate abundant, low-cost electricity. Washington has the 4th-lowest electricity rates in the nation at roughly 10 cents/kWh vs the national average of 16 cents/kWh.

Alex — Software Engineer Moving from California to Spokane, WA

Currently earning $100,000 in California (COL 134). Considering Spokane, WA (COL 92). Single filer, no dependents.

California salary$100,000

CA state income tax (~7.5%)-$7,500

Federal tax + FICA-$21,078

CA take-home$71,422

CA purchasing power (COL 134)$53,300

WA salary needed for same power$71,400

WA state income tax$0

WA Cares (0.58%) + PFML (0.54%)-$799

Federal tax + FICA-$16,221

WA take-home$54,380

Spokane purchasing power (COL 92)$59,109

Alex could take a $28,600 pay cut and still have the same lifestyle in Spokane vs California. If Alex keeps the $100K salary remote, purchasing power jumps to $86,090 — a 62% real raise.

Frequently Asked Questions

How does Washington's cost of living compare to the national average?▼

Washington's overall COL index is 107, meaning it costs 7% more than the national average to live there. However, this is heavily skewed by Seattle (152). Outside the Seattle metro, many WA cities are at or below average: Spokane (92), Tri-Cities (94), Vancouver WA (104). The statewide average is pulled up by housing (121) and transportation (110), while utilities (83) and healthcare (102) are well below or near average. When you factor in $0 income tax, Washington's effective cost for many workers is lower than states with similar COL but income tax obligations.

Why are Washington utilities so cheap?▼

Washington's utility index of 83 (-17% below average) is primarily due to the Columbia River hydropower system — the largest in the United States. Over 30 dams, led by Grand Coulee Dam, generate abundant low-cost electricity. Washington has the 4th-lowest electricity rates in the nation at roughly 10 cents per kWh compared to the national average of 16 cents per kWh. This saves a typical household $800-1,200 per year on electricity alone. Natural gas costs are also below average thanks to proximity to Pacific Northwest gas infrastructure.

Is Spokane really cheaper than the national average?▼

Yes. Spokane's overall COL index is 92, meaning it's 8% below the national average. Housing is the biggest factor — Spokane's housing index is 82, with median home prices around $365,000 (vs $420,000+ nationally). Combined with Washington's $0 income tax and cheap hydropower utilities, Spokane offers a rare combination: below-average living costs in a no-income-tax state. The trade-off is smaller job market (healthcare, education, Fairchild AFB) and harsher winters than western WA.

How does Seattle's cost of living compare to San Francisco?▼

Seattle's COL index is 152, high but still well below San Francisco (179). The biggest difference is housing: Seattle 195 vs SF 250+. However, the real advantage is taxes. Seattle workers pay $0 state income tax while San Francisco workers pay California's progressive tax (up to 13.3%). On a $150,000 tech salary, you'd keep roughly $12,000-15,000 more per year in Seattle than San Francisco between income tax savings and lower housing costs. Seattle's main cost disadvantage vs SF is its higher sales tax (10.3% vs 8.6%).

What about Washington's high sales tax?▼

Washington compensates for $0 income tax with a relatively high sales tax: 6.5% state rate plus local additions averaging 2-4%, making combined rates 8.5-10.5% depending on location (Seattle is 10.35%). This impacts spending on goods but not services, food for home consumption, or prescription drugs (all exempt). For most workers, the income tax savings far exceed the extra sales tax paid. Someone earning $80,000 saves $3,000-6,000 in income tax vs a typical state, while paying roughly $1,500-2,500 extra in sales tax on their spending. Net benefit: $500-3,500/year depending on spending habits.
