South Dakota LLC formation cost

Forming a South Dakota LLC costs $150 in state fees to file the Articles of Organization online, or $165 on paper. SDCL 47-34A-212(a) sets the $150 base fee, and subsection (c) prices articles for a domestic series LLC at $200. Beyond that one-time payment, your first-year budget depends on whether you hire a registered agent, a formation service, or an attorney or CPA.

South Dakota has no corporate income tax, which the Department of Revenue confirms on its business taxes page, and no personal income tax, per the DOR individual taxes page. It also imposes no general franchise tax on LLCs. Your only routine recurring state fee, as long as the LLC stays in good standing, is the $55 online annual report, or $70 on paper, per the SOS fee schedule. Fees that low make the state attractive to founders and multi-entity operators.

Required South Dakota LLC formation costs

At formation, the Articles fee is the only required state filing payment. The registered agent and operating agreement cost nothing if you handle them yourself.

The online fee covers the Articles of Organization submission that SDCL 47-34A-203(a) governs; the South Dakota LLC filing fee breakdown compares both methods. Mailing adds the $15 surcharge from SDCL 1-8-13.1, which the SOS fee schedule includes in the $165 total.

SDCL 59-11-5(1) requires addresses in agent filings to be "an actual street address or rural route box number in this state," and subdivision (2) adds an in-state mailing address if it differs. The SOS FAQ confirms that the agent needs both a physical and a mailing address in South Dakota.

As for what a registered agent does, the job is limited to receiving and forwarding service of process and state notices. SCORE has estimated commercial agent fees at $100 to $300 per year, though pricing varies by provider. Under SDCL 47-34A-103(a), an operating agreement is optional and "need not be in writing."

Optional LLC formation costs in South Dakota

Optional spending falls into two buckets, professional help and extra state filings, and South Dakota law requires neither.

1. Professional services

Multi-member LLCs, layered ownership, or unusual tax positions may justify an attorney. Florida firm LegalCounselPA's cost guide puts flat-fee formation packages at $500 to $2,500, typically including the Articles, a custom operating agreement, and an EIN; South Dakota pricing may run lower. Hourly work is cheaper here than in most states: Clio's South Dakota data puts the 2025 average lawyer rate at $252 an hour, against $349 nationally. CPA consultations run $150 to $500 per hour, according to NerdWallet's startup costs guide.

Online LLC formation services sit between DIY and a law firm. NerdWallet's LLC service review found entry tiers priced at $0 plus state fees, and Forbes Advisor puts midrange packages at $79 to $199 plus the state fee. Some packages also bundle a registered agent subscription.

2. Additional filings

Some filings appear only when you need them. Fees below come from the SOS fee schedule.

• Name reservation costs $25 under SDCL 47-34A-1206(e), and SDCL 47-34A-106 holds the name for 120 days.

• Expedited processing costs $50. The SOS FAQ says online filings are processed immediately and paper filings average 1 to 3 business days, so the fee matters mainly for paper submissions.

• DBA registration costs $10 per name for a five-year term, per the SOS FAQ.

• Certificates of good standing cost $20 online and $35 on paper.

• Your EIN is free from the IRS.

Local licensing depends on your industry and city. The Sioux Falls Licensing Office, for example, licenses certain regulated business categories, such as alcohol sales and pawnbrokers. The state sales tax license is free, per the DOR license fact sheet.

Ongoing annual costs for forming an LLC in South Dakota

After formation, the annual report is the only routine recurring state fee, and missing it costs more than the fee itself. Budget for these line items each year:

• The South Dakota LLC annual report, at $55 online or $70 on paper

• South Dakota registered agent fees, $0 if you serve yourself or $100 to $300 for a commercial agent

• Local business licenses, which vary by city and industry

• Professional services, such as tax preparation or legal review

The report is due on the first day of your anniversary month, and the SOS opens filing two months earlier, per the SOS FAQ. If the report is still unfiled two months after the due date, the entity becomes delinquent and owes a $55 late fee under SDCL 47-34A-212(b). Once a report is sixty days late, SDCL 47-34A-809(2) lets the SOS begin administrative dissolution, and SDCL 47-34A-810 requires the SOS to serve notice and allow sixty days to correct the problem before dissolving the LLC. Starting January 1, 2027, an amended SDCL 59-11-25 has each entity file either during its anniversary month or by January 31, and new entities state that choice on the formation document.

As the South Dakota franchise tax guide explains, the state imposes no general franchise tax on LLCs. The exception is the bank franchise tax, which can reach financial institutions organized as LLCs, including money lenders. For most LLCs, you avoid the entity-level charge that a franchise tax typically adds in other states. The Tax Foundation's 2025 index calls South Dakota one of only two states, with Wyoming, that levy no individual income, corporate income, or gross receipts tax.

FAQs about LLC formation costs in South Dakota

These are the questions that come up most often when founders and finance teams budget for a South Dakota LLC.

Are there any hidden fees when forming a South Dakota LLC?

Most surprises come from commercial registered agent fees, formation-service upsells, and industry-specific city licenses. The $15 paper surcharge also catches people who mail forms they could file online.

Can I get refunds if my South Dakota LLC filing is rejected?

The SOS fee schedule and FAQ don't describe a refund policy for rejected filings, so contact the SOS Business Services division before you submit if a refund matters.

How do South Dakota LLC costs compare to other states?

South Dakota's formation and annual fees sit well below high-fee states. California charges an $800 annual LLC tax, and Massachusetts charges $500 to form and $500 for each annual report, per its corporations fee schedule.

Can I serve as my own registered agent?

Yes, if you live in South Dakota. The SOS FAQ allows a noncommercial agent who is an individual residing in the state, and the agent needs both a physical and a mailing address there. Many owners still pay a commercial agent so someone is always available to receive service.
