Creating a South Dakota LLC involves a series of legal steps outlined in Chapter 47-34A of the South Dakota Codified Laws. Skip any of these requirements, and you risk rejected filings that delay your business launch, potential personal liability exposure, and administrative dissolution that strips away your limited liability protection.
These requirements cut across:
Your LLC name must include "Limited Liability Company," "Limited Company," or approved abbreviations like "LLC," "L.L.C.," "LC," or "L.C." South Dakota won't approve your Articles of Organization without this identifier. "Limited" may be abbreviated as "Ltd." and "Company" as "Co."
South Dakota applies strict distinguishability standards based on how names sound when read aloud, not just spelling. Adding punctuation, changing capitalization, or switching between singular and plural forms doesn't create a distinguishable name. "Wheat Grass Juice LLC" would be rejected if "Wheatgrass Juice Corp." already exists. Restricted words include:
You can reserve your chosen name for 120 days by filing a reservation request with the Secretary of State for $25. Check availability through the South Dakota Secretary of State's Business Information Search tool before filing to avoid rejected applications.
South Dakota law requires every LLC to continuously maintain a registered agent with a physical address in the state for receiving legal documents, tax notices, and official correspondence.
Qualification criteria:
South Dakota recognizes noncommercial agents (typically individuals) and commercial registered agent services with state-issued CRA numbers. Your agent's information becomes part of public records through the Secretary of State's database.
Failing to maintain a registered agent can result in administrative dissolution, loss of good standing status, and missed legal notices, leading to default judgments. Changes to registered agent information require prompt updates with the Secretary of State.
The Articles of Organization legally create your LLC in South Dakota and must be filed with the Secretary of State along with the required filing fee.
Required information:
Filing costs $150 online or $165 by mail, with expedited processing available for an additional $50. Online filings typically receive same-day approval, while paper submissions take several business days. The organizers must sign the document, and all information becomes part of the public record.
South Dakota law doesn't require operating agreements to be filed with the state, but this internal document is highly recommended for both single-member and multi-member LLCs. Without an operating agreement, your LLC defaults to state law provisions that rarely match your actual business needs.
Single-member LLCs benefit from operating agreements that clearly establish the separation between personal and business activities, helping prevent courts from piercing the corporate veil. The agreement demonstrates that your LLC functions as a legitimate separate entity rather than an extension of personal activities.
Multi-member LLCs face greater risks without operating agreements since internal disputes become inevitable. Your agreement should establish ownership percentages, voting rights, profit distributions, procedures for adding or removing members, and dispute resolution methods. Including mediation clauses prevents internal conflicts from escalating into public court battles that damage your business reputation.
Operating agreements provide crucial legal protections by overriding default state laws, protecting managers from liability, and establishing clear procedures for major business decisions. Since these agreements remain private and don't require state filing, you maintain operational flexibility while strengthening liability protection.
Post-formation requirements begin immediately with specific deadlines that require systematic tracking. Some of these requirements include:
South Dakota imposes escalating consequences for LLCs that fail to meet formation or ongoing requirements, starting with immediate penalties and progressing to complete loss of legal protections.
