Learn moreNo state individual income tax
South Dakota is one of only 9 US states with no state individual income tax at all, and therefore none on Social Security, pensions, or retirement-account withdrawals -- this applies in Yankton as statewide, a real, direct benefit given Yankton's above-state-average median age.
A below-national-average combined sales tax
South Dakota's 4.2% state sales tax rate (time-limited, scheduled to rise to 4.5% on July 1, 2027) combines with local add-ons to a statewide average of approximately 5.99%, below the roughly 7% national combined-rate average.
