State guide

Fees, taxes, privacy, timelines, and banking for forming an LLC in South Dakota — with pros, cons, and a side-by-side comparison so you can decide with confidence.

Why form an LLC in South Dakota?

Worth considering only if you actually operate in South Dakota. Its draw is no state income tax, but a remote or non-US founder gets the same tax-free formation plus stronger privacy from Wyoming.

A quick reminder from us: forming in a state where you do not actually operate usually means you still have to register (foreign-qualify) in your home state, often with little or no tax benefit. If you are unsure, tell us how you plan to operate and we will recommend the right fit — free.

Costs and fees

The South Dakota Secretary of State charges roughly $150 to file Articles of Organization, with an ongoing state cost of about $55/yr report (online). No state income tax or franchise tax; the main ongoing cost is the ~$55/yr online annual report ($70 by paper). State fees are paid directly to the state and are separate from our service fee.

  • Filing fee: $150 (approximate)
  • Ongoing state cost: $55/yr report (online)
  • Typical processing time: 1–2 days

Taxes and privacy

Personal state income tax in South Dakota: None. Owner privacy on the public record is generally rated low.

Your federal tax obligations (and your EIN) are the same regardless of the state you choose — a single-member LLC is taxed as a pass-through by default, and we can obtain your EIN even if you do not have an SSN.

Pros of forming in South Dakota

  • No state personal income tax and no corporate income tax
  • No franchise tax
  • Fast online filing — often same day to ~2 business days
  • Relatively simple ongoing compliance (one annual report)

Things to weigh

  • $150 formation fee is higher than several states
  • The annual report publicly lists members/managers, so ownership privacy is low
  • Annual report fee rose to $55 online / $70 paper as of July 1, 2025 — a recurring cost
  • No real edge over Wyoming for a non-resident (Wyoming is cheaper to renew and more private)

Banking for your South Dakota LLC

Banking is provider-based, not state-restricted — an SD LLC opens accounts with the same fintechs and national banks as any other. South Dakota's no-income-tax status doesn't change bank KYC for foreign owners.

Whichever state you choose, we prepare the documents banks ask for and can obtain your EIN even without an SSN. Bank and provider approval is always their decision — we are not affiliated with any bank.

Is South Dakota right for you?

Best for: SD residents / SD operations. If you operate physically in South Dakota, forming here keeps things simple. If you are a remote or non-US founder without a specific reason to choose South Dakota, a low-cost, privacy-friendly state like Wyoming or New Mexico is often the better default.
