South Dakota Company Formation and Compliance Guide

Before forming or operating a company in South Dakota, review entity type, registered-agent records, annual reports, state tax, federal tax, and e-commerce bookkeeping requirements.

Reference LLC state filing feeThe standard online fee for LLC articles of organization is generally $150; paper filing is generally higher. Confirm on the state website before filing.
Ongoing filingThe online annual report fee is generally $50; paper filing is generally higher. Confirm on the state website before filing.
Typical due-date ruleThe annual report is generally due before the first day of the anniversary month.

01

What to confirm before filing

Confirm entity type, owners, management, name, business activity, registered agent, and any in-state address requirements. An LLC and a corporation have different governance, tax elections, and recurring filings; first-year price alone is not a sound basis for choosing.

South Dakota's economic-nexus rules are a leading example of duties arising without a physical location.

02

Ongoing state compliance

The online annual report fee is generally $50; paper filing is generally higher. Confirm on the state website before filing. The annual report is generally due before the first day of the anniversary month.

03

E-commerce and sales tax

Cross-border sellers should test economic nexus using sales, transactions, inventory, and marketplace collection records. Do not treat the absence of an in-state office as proof that registration is unnecessary.

04

Federal tax and foreign ownership

State formation does not replace federal tax filing. A U.S. entity with foreign ownership may involve an EIN, Form 1120, Form 5472, Form 1065, withholding, or information returns. The applicable filing depends on tax classification, ownership, transactions, and operating facts.

05
