The right reserve percentage for South Dakota
South Dakota charges no individual income tax, so only federal income tax and the 15.3% self-employment tax apply. That is why the blanket "save 30%" advice misses here: South Dakota filers typically need 25-30% of net profit, not a round number borrowed from someone in another state.
South Dakota has no individual income tax.
The mechanic matters more than the number. Tax trouble is a cash failure, not a math failure — money arrives, looks like income, and gets spent. Moving the reserve out the day each deposit lands is what keeps the South Dakota and federal bills funded.

What are the quarterly deadlines in South Dakota?

Are there local taxes to reserve for in South Dakota?
