South Dakota in the $100K burden neighbourhood
South Dakota versus the states next-most-affordable for taxes
Other US states ranked just above South Dakota on the $100K single-filer state-tax burden, the next tier of "low-tax" jurisdictions.
Because South Dakota has no state income tax, the meaningful comparison isn't "neighbors above and below" (everyone with tax is "above" us at any income level) - it's the nearest tier of low-tax states a South Dakota resident might compare against if they relocated. Each card below shows that state's top marginal rate, structure, and the dollar burden a $100K single filer would face. Compared to South Dakota's $0, the gap is the cost-of-tax of moving away from one of the nine no-income-tax jurisdictions.
