How South Dakota taxes retirement income
- South Dakota has no state income tax, so Social Security, pensions, IRA and 401(k) withdrawals, Roth conversions, interest, dividends and capital gains are not taxed by the state.
- Federal income tax and Medicare premiums still apply, and they're where most retirement tax planning happens.

Detail
No state individual income tax (DOR: 'one of seven states that does not impose a state income tax').
This page covers income tax only. Property, sales and estate or inheritance taxes are separate. Taxtirement does use your state's sales tax for the federal itemized deduction when that's larger.
