South Dakota LLC Costs — What You Actually Pay

The unavoidable cost to start a South Dakota LLC is the state filing fee for the Articles of Organization, paid to the Secretary of State. South Dakota charges less for online filing than for paper, which is one more reason to file electronically. The current figures are published on the state's fee schedule, and the receipt card on this page shows exactly what you pay when you form through us.

What the formation fee covers

The Articles of Organization fee registers your LLC and puts it on the state's records. It's a flat fee — it doesn't scale with the number of members, your projected revenue, or the type of business. Once it's paid and the filing processes, your LLC legally exists.

Optional one-time costs at formation

• Name reservation — if you want to lock your name before filing, South Dakota charges a small fee to reserve it for 120 days. Most people skip this and simply file when ready.
• Certified copies — if a bank, lender, or partner needs a certified copy of your Articles, the state charges a per-document fee.
• Fictitious/assumed name (DBA) — if you'll operate under a name other than your legal LLC name, registering that name carries its own fee, whether you file with the Secretary of State or the county Register of Deeds.

None of these are required to form a basic LLC. The one cost everyone pays is the Articles of Organization filing fee.

South Dakota's ongoing costs are refreshingly light, and there's no franchise tax or state income tax lurking in the background.

The annual report

Every South Dakota LLC files an annual report with the Secretary of State each year, and there's a fee attached — lower online than on paper, consistent with the state's pattern. The report is due by the first day of your LLC's anniversary month. It's not a financial disclosure; it confirms your registered agent, address, and management details. The receipt card and our annual-requirements page cover the specifics.

Registered agent renewal

If you serve as your own registered agent, this costs nothing beyond your time. If you use a commercial registered agent — which many owners do for privacy and reliability — that service renews annually. It's a predictable, flat recurring cost, and for out-of-state owners it's effectively mandatory since you need a physical South Dakota address. Form through Mainstay, though, and there's no standalone agent renewal to remember: the agent stays on duty under the same flat yearly service that also takes care of the annual report.

What you won't pay

• No franchise tax — South Dakota doesn't levy one on LLCs.
• No state income tax — no personal or corporate income tax means no state income tax filing for your pass-through LLC.
• No mandatory publication — unlike a few states, South Dakota doesn't require you to publish a formation notice in a newspaper.

Beyond the core formation and annual costs, several expenses come up depending on how your business evolves. None are required to keep a basic LLC in good standing, but it helps to know they exist.

Amendments

If you change your LLC's name, switch its management structure, or update other information in your Articles, you file an amendment with the Secretary of State, which carries a fee. Routine updates like an address change may be handled through the annual report or a change filing.

Registered agent changes

Switching your registered agent — from yourself to a commercial service, or between providers — is a change filing with a modest state fee.

Certified documents and good standing certificates

Banks, lenders, and other states (if you expand) may ask for certified copies of your Articles or a Certificate of Good Standing. Each carries a per-document state fee.

Foreign qualification (in reverse)

If your South Dakota LLC later expands into another state, you'll register there as a foreign LLC, which means that state's filing fees and its own registered agent requirement. That's a cost of the destination state, not South Dakota.

Dissolution

When you close the LLC, filing Articles of Dissolution with the Secretary of State finalizes the closure. Formally dissolving stops annual report and agent costs from continuing to accrue, so it's worth doing rather than simply abandoning the entity.

Thinking about cost over time helps you plan realistically instead of focusing only on the day-one fee.

Year one

Your first-year cost is the Articles of Organization filing fee plus, if you hire one separately, a standalone commercial agent's fee — or, through us, a single flat yearly service amount with the agent already inside it. Optional add-ons — a name reservation, a DBA, certified copies — only apply if you specifically need them. Getting an EIN from the IRS is free, so it doesn't add to your budget.

Every year after

Ongoing, you're looking at the state's annual report fee and, if you keep a standalone commercial agent, that provider's renewal. That's it for state-level recurring costs. With no franchise tax and no state income tax, South Dakota keeps the annual carrying cost of an LLC low compared with many states.

Where costs can sneak up

The most common avoidable cost is a late annual report fee. Because the deadline tracks your anniversary month rather than a fixed calendar date, it's easy to lose track of — which is exactly why owners either set a firm reminder or use a service that files it for them. A late fee is small, but administrative dissolution and reinstatement are not, and both stem from the same missed deadline.

What Mainstay Filing includes

When you form with us, the receipt on this page shows the full, itemized cost with no hidden markups — what's displayed is what's charged. One flat amount each year covers preparing and filing your Articles of Organization, acting as your registered agent for every year we serve you, and preparing and filing the annual report itself, so a low-cost obligation never becomes an expensive problem.
