Who issues an LLC Formation in South Dakota

In South Dakota, an LLC formation is issued by the office below. That is the office to confirm every figure with.

Starting point for anything else in South Dakota: the state business portal, https://sosenterprise.sd.gov/BusinessServices. It is a starting point, not the issuer of this permit.

The general US process

This sequence is the shape the process takes across the US. It is not a list of South Dakota requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.

  1. Step 1: Pick a name and check it against the state's business-entity register — most states let you search this online for free.
  2. Step 2: Name a registered agent with a physical street address in the state; a PO box is generally not accepted.
  3. Step 3: File the formation document — usually called Articles of Organization or a Certificate of Formation — with the state's business-filing office.
  4. Step 4: Pay the state filing fee. This is the one figure on this page that we do hold per state, shown above.
  5. Step 5: Get an EIN from the IRS. It is free, online, and usually issued immediately.
  6. Step 6: Open a business bank account in the LLC's name using the EIN and the filed formation document.
  7. Step 7: Write an operating agreement. A handful of states require one; in the rest it is optional and still worth having.

What varies: the filing fee, the name of the form, how often the state wants a report, and whether the state adds its own publication or franchise-tax step. New York, for example, adds a newspaper publication requirement.

Documents usually asked for

A typical list, not a South Dakota checklist.

Heads up: Put the renewal in a calendar now. Most states require a periodic report; the interval and the fee vary by state — and reminder letters are a courtesy, not a guarantee, in most of the country.
