Common questions about South Dakota LLC taxes and fees
Forming an LLC in South Dakota requires a $150 filing fee paid to the South Dakota Secretary of State. After formation, South Dakota LLCs must pay a $50 annual fee for the annual report.
| Fee Type | Amount | Frequency |
|---|---|---|
| Articles of Organization (filing fee) | $150 | One-time |
| Annual Report / Annual Fee | $50 | Yearly |

Maintaining your South Dakota LLC in good standing requires meeting several compliance obligations.
Annual Report: South Dakota LLCs must file an annual report by First day of anniversary month. The filing fee is $50.
Registered Agent: Every South Dakota LLC must maintain a registered agent with a physical address in the state. The registered agent receives legal and tax documents on behalf of the LLC. You can serve as your own registered agent or hire a professional service (typically $125/year).
Operating Agreement: While South Dakota does not legally require an operating agreement, having one is strongly recommended. It defines ownership structure, member roles, profit-sharing, and management procedures for your LLC.
EIN (Employer Identification Number): All LLCs with more than one member, or that have employees, need an EIN from the IRS. Single-member LLCs without employees can use their Social Security number but obtaining an EIN is still recommended for banking and tax purposes. Applying is free through the IRS website.
South Dakota LLCs are classified as pass-through entities for federal tax purposes. A single-member LLC is treated as a disregarded entity (reported on Schedule C of the owner's personal return), while a multi-member LLC is taxed as a partnership (filing Form 1065 with K-1s issued to each member).
South Dakota has no state income tax, which is a significant advantage for LLC owners. LLC profits pass through to members' personal tax returns, and since South Dakota does not tax personal income, your LLC earnings are not taxed at the state level.
S-Corp Election: South Dakota LLCs can elect S-Corp tax status by filing IRS Form 2553. This can reduce self-employment taxes for profitable LLCs by splitting income between a reasonable salary (subject to payroll taxes) and distributions (not subject to SE tax). This election is typically beneficial when your LLC consistently earns over $40,000-$50,000 in annual profit.
