How Much Does It Cost to Form a South Dakota LLC?
South Dakota is priced in the middle of the national range for LLC filing fees. But the state filing fee is only part of the picture. This page breaks down every cost you'll encounter — formation, ongoing compliance, and optional services — so there are no surprises.
State Filing Fee
The South Dakota Secretary of State charges $150 to file your Articles of Organization. This is a one-time fee paid when you form the LLC.
Annual / Recurring State Fees
South Dakota charges $55 for the annual report (filed each year). Miss it, and you risk late fees and eventually administrative dissolution.
South Dakota tax note: Annual report increased from $50 to $55 (online) effective July 1, 2025. $70 by mail. No state income tax. No corporate income tax.
Registered Agent Cost
Every South Dakota LLC is required to maintain a registered agent. With our formation package, the first year of registered agent service is included. After that, ongoing service is $99/year.
Expedited Processing
If you need your LLC formed faster, the South Dakota Secretary of State offers expedited processing for $50. This typically reduces the turnaround from 5-7 business days to 24 hours.

Many LLC formation services charge $199-level fees but then tack on upsells: compliance packages, rush fees, unnecessary add-ons. Our fee is straightforward — $199 covers everything you need to get your South Dakota LLC filed and operational.
