What a bookkeeper tracks in South Dakota

General information, not tax advice. Which of these reach your business depends on its entity type, what it sells, whether it has employees and the schedule each agency assigns. Your bookkeeper keeps the records; you, or whoever your engagement letter names, file. Checked on the linked official pages on September 26, 2026.

  • Sales and use tax. The Department of Revenue tells each licensed business how often to file. Whatever your frequency, the return is due by the 20th of the following month, and electronic payments are due by the 25th. South Dakota Department of Revenue, checked Sep 26, 2026
  • No state income tax. South Dakota has no personal or corporate income tax, so there's no state income tax withholding on paychecks. South Dakota Department of Revenue, checked Sep 26, 2026
  • Reemployment assistance reports. Wage reports go to the Department of Labor and Regulation every quarter and must be received by April 30, July 31, October 31 and January 31. A report is still due for a quarter with no wages. South Dakota Department of Labor and Regulation, checked Sep 26, 2026
  • Annual report. Annual reports go to the Secretary of State every year, due the first day of the month in which your business was originally filed. Limited partnerships and business trusts are exempt, and the fee depends on entity type. South Dakota Secretary of State, checked Sep 26, 2026
  • CPA title. Under South Dakota law, only a person holding a valid certificate or practice privileges may use the title certified public accountant or the abbreviation CPA. South Dakota Legislature, checked Sep 26, 2026
