South Dakota keeps the modeled household bill about $307 lower than Washington. Neither state taxes wages. One fixed household — single filer, $100,000 wages, $400,000 home, $20,000 of taxable spending — so property, sales, and modeled employee PFML decide the gap.

Washington vs South Dakota with no wage income tax (2026)
Both states are on the nine-state list. This page holds the household constant — $100,000 single-filer wages, a $400,000 home, $20,000 of taxable spending — then adds paycheck tax, property tax, and sales tax so neither state can look cheaper just by skipping wage PIT.
South Dakota models the lower total by $307 a year. Read the line items — the winner often wins on property or sales, not on the paycheck.
Washington does not tax wages. This vignette includes modeled employee Paid Family and Medical Leave (PFML). Washington also levies a separate capital gains excise on certain long-term gains — not a wage income tax. South Dakota does not tax wages. Property tax is the larger add-on versus Wyoming or Nevada on this vignette.
How Washington and South Dakota split the bill
Washington: $21,435 paycheck, $3,000 property, $1,914 sales. South Dakota: $20,820 paycheck, $4,000 property, $1,222 sales.
Take-home is not identical: $78,565 in Washington vs $79,180 in South Dakota ($615 apart) because modeled employee PFML differs.
As a share of wages the combined bill is 26.4% in Washington vs 26.0% in South Dakota.
Tax total vs cost of living
Washington’s COL index is 114.6; South Dakota’s is 94.1 (US average = 100). A lower household tax total can still sit in a more expensive grocery and rent basket.
Among the nine, Tennessee has the lowest COL index (88.9) and Alaska the highest (129).
Use the tax columns to compare levies and the COL column to compare prices. They answer different questions.
What this comparison leaves out
Local city wage taxes are not in play here (none of the nine models a separate city PIT on this vignette). Employer payroll taxes, credits beyond calculator defaults, and Washington’s capital gains excise on certain long-term gains are excluded from the wage household total.
Property uses a statewide effective rate on a fixed $400,000 home — not your county millage or purchase price. Sales tax uses a combined state + average local rate on a fixed $20,000 basket.
The nine-state range at $100,000 is $24,018 (Wyoming) to $28,060 (Texas).
The same pair at other salaries
Home value and spending stay fixed, so the ladder mostly moves with paycheck tax. At $75,000, South Dakota is lower by $153. At $150,000, South Dakota is lower by $615.
If you itemize, buy a different-priced home, or spend more on taxable goods, reorder the pair in the property and sales hubs rather than treating this ladder as a forecast.
Concepts to know for this comparison
Short definitions so the wage, property, sales, and COL lines add up the way you expect.
Wage PIT is already zero
The interesting gap is property, sales, and (for Washington) modeled employee PFML — not a state wage bracket.
Household total
Add paycheck tax, property on $400,000, and sales on $20,000. That is the ranking metric on the hub.
COL index
