South Dakota in November 2016: the cheap LLC in the trust state
A $150 filing fee, a $50 annual report, and a jurisdiction whose real business is holding other people's wealth
Contents 5 sections
South Dakota LLC costs $150 to form and $50 a year to keep. There is no state income tax. The Secretary of State turns around online filings in about a day. Those are the operational numbers, and on their own they would make this a small, cheerful guide to a cheap, efficient state.
The reason the guide is not small is that South Dakota's formation market is dominated by something adjacent to the ordinary LLC: a trust industry that has become, over the last decade, the most aggressive in the country. Understanding why entities end up here at all means understanding that gravitational field.
The mechanics
You file Articles of Organization with the South Dakota Secretary of State in Pierre. The form is short: name of the LLC, purpose (a general-purpose clause is accepted), registered office in South Dakota, registered agent in South Dakota, duration (perpetual is standard), management structure (member-managed or manager-managed), and a signature from an organizer.
The fee is $150, paid online or by mail. The state's online portal is the faster route; paper filings add a week. Turnaround online is typically same-day or next-day, which puts South Dakota near the top of the field on responsiveness. There are no meaningful expedite tiers because the baseline is already fast enough that the market for faster has not developed.
You will need an EIN from the IRS, which is a Form SS-4 online and a fifteen-minute exercise. South Dakota does not require an operating agreement to be filed, but you should have one; the default statutory rules are reasonable but thin, and members who skip the agreement tend to discover its absence exactly when they needed it. Federal tax election is handled through the IRS, not the state — disregarded for single-member, partnership for multi-member, S- or C-election by separate form if you want them.
A word on the registered agent. South Dakota requires a physical address in the state, and the commercial-agent market is smaller and less competitive than Delaware's or Wyoming's. Prices sit in the $100 to $200 range for most commercial providers. The difference between the commodity end and the full-service end is the same everywhere: whether your agent catches service of process and forwards it that day, or lets it sit.
Maintenance
South Dakota's annual report is due on the first day of the LLC's anniversary month every year. The fee is $50, and you file through the Secretary of State's online portal. The state will email a reminder if you give it an address it trusts; it will not otherwise chase you. Miss the deadline by sixty days and the LLC falls out of good standing; miss it longer and administrative dissolution follows. Reinstatement is possible and inexpensive, but a lapse creates a gap in your good-standing history that some banks and counterparties will notice.
There is no state corporate income tax, no personal income tax, and no franchise tax on LLCs. This is the cleanest maintenance picture among the commonly discussed formation states. What you pay is the $50 annual report and the registered-agent fee, and that is the full carry.
The trust overlay
South Dakota's ordinary LLC formations are not the reason the state has a national profile. The reason is trusts. Over roughly the last two decades, the South Dakota legislature has written and repeatedly updated a trust code that is, on most reasonable measures, the most planner-friendly in the United States. Dynasty trusts with no rule against perpetuities. Directed trusts that split investment, distribution, and administrative roles among different fiduciaries. Self-settled asset-protection trusts. Decanting. Privacy provisions that seal court files on trust disputes. A Trust Task Force that meets annually and ships amendments the following session.
The visible outcome is a chartered trust-company industry that has grown past a hundred institutions, many of them serving a single family or a small club of families. The less visible outcome is that a meaningful share of the LLCs forming here are not operating companies at all. They are holding vehicles sitting under a South Dakota trust, or beside one, as part of a larger estate-planning structure assembled by a lawyer in New York, Chicago, Houston, or San Francisco.
This matters for a reader forming an ordinary LLC because it shapes the professional-services market around you. The South Dakota trusts-and-estates bar is deep; the South Dakota operating-company bar is thinner than you would expect for a formation state. If you are forming a holding entity that will eventually sit under a dynasty trust, the talent is here. If you are forming an operating LLC that needs a commercial-litigation opinion on a vendor dispute, you may end up looking elsewhere.
Privacy, in context
South Dakota is private enough for most purposes. The Articles of Organization do not require member names; organizer identity is what appears on the public filing. Annual reports do disclose a manager or member, depending on management structure, which is more than Wyoming requires and less than many operating states.
If privacy is the single thing you are buying, Wyoming remains the stricter choice. South Dakota's privacy is a by-product of a state that built its reputation around trust confidentiality, not an ordinary-LLC feature engineered on its own. For trust-adjacent structures the difference is immaterial; for a standalone operating LLC where anonymity is the point, Wyoming is the more direct answer.
Who this state actually makes sense for
Three kinds of entity belong in South Dakota in late 2016.
The first is anything that sits inside or next to a South Dakota trust. If the estate-planning work is already here, the holding LLCs should be here too. The costs are low, the statute is stable, and the local professional services are aligned around this pattern.
The second is a holding vehicle for high-net-worth planning that has not yet committed to a trust structure but expects to. Forming in South Dakota at the outset avoids a later redomicile and keeps the eventual trust work inside a familiar jurisdiction.
The third is a resident. South Dakotans forming operating LLCs for local businesses have every reason to form at home and no reason to pay for Delaware or Wyoming window dressing.
Everything else — the California consultancy, the Texas rental-property LLC, the two-person software shop in Brooklyn — should form at home or in Wyoming. An operator based elsewhere who forms in South Dakota will still have to foreign-qualify in the state where the business actually operates, which means paying two filing fees, two annual reports, and two registered agents for the benefit of a mailing address in Pierre. That math rarely closes.
If you are forming this quarter and the structure is trust-adjacent, file South Dakota and get the lawyer who is doing the trust work to do the LLC at the same time. If it is not trust-adjacent, the state is a perfectly decent formation jurisdiction that is almost certainly not the one you want.
