Fee, timeline, and tax basics for a South Dakota LLC.
A South Dakota LLC is not taxed differently than a sole proprietorship by default; profit simply passes through to your personal return. Any savings come later from an S-corp election once your South Dakota LLC is consistently profitable enough to justify the extra payroll work. South Dakota has no state personal income tax, which keeps its overall LLC tax picture simple compared with most states.
South Dakota charges $150 to file the Articles of Organization, on the pricier side compared with most other states. Processing time depends on how South Dakota is running that week and whether you file online or mail it in; check the South Dakota Secretary of State site for the current estimate before you plan around it. On the ongoing side, South Dakota charges a moderate recurring fee that is easy to plan around ($50).
Between the $150 filing fee and an optional registered-agent service, most South Dakota LLC owners have a clear first-year number well before they file anything. Use the LLC cost calculator to run your own numbers through the cost calculator for South Dakota, then check the sole proprietor comparison to check if the LLC paperwork is worth it for you.
