What happens if I miss or underpay a quarterly estimated tax deadline in South Dakota?
Underpaying or missing a quarterly deadline can result in statutory interest penalties from the IRS and the South Dakota Department of Revenue.

In South Dakota, forming an LLC and electing S-Corporation tax status can significantly reduce your 15.3% federal self-employment tax on net business profits exceeding $60,000–$80,000 by splitting income into W-2 salary and pass-through distributions, with zero state income tax friction.
