SHEET SD-01 · FORMATION DOSSIER

South Dakota

Form an LLC in South Dakota as a non-resident: the verified state fee, the duty that follows you every year, the agent rule, and the traps that are specific to this state — each figure sourced on this sheet.

State formation fee: $150
Total with Formation Complete: $549
Annual duty cost: $55/yr
Report pattern: Due every year on the 1st day of the anniversary month of initial filing with the SOS. SOS exam

On fee alone, South Dakota is the 39th cheapest of the 49 jurisdictions in this Atlas to form in. Fee is the smallest part of the decision — the duty below is the part that repeats.

What it takes here

You form a South Dakota LLC by filing Articles of Organization with the South Dakota Secretary of State, Business Services. The state fee is $150, collected by us at cost as a pass-through — the state keeps its fee; our $399 is separate and labelled as ours on the pricing page. The current Secretary of State fee schedule — the sdsos.gov fee schedule — lists the LLC Annual Report at $55 filed electronically online and $70 filed on paper (including the $15 paper fee); older annual report forms showing $50/$65 are out of date.

Name rules

Your company name must contain a limited-liability designator — “Limited Liability Company” or an accepted abbreviation such as “LLC” — and must be distinguishable from names already on the records of the South Dakota Secretary of State, Business Services. A name that implies a regulated activity (banking, insurance, trust) or a government affiliation invites rejection or a consent requirement in South Dakota as in most states. For a non-resident there is a second, quieter naming point: the name on the Articles of Organization is the name the IRS will print on your EIN confirmation (the CP 575), and it is the name your bank and payment processors will match against your documents. Pick the final name before filing; amending it later is a second state filing with a second fee.

Publication

South Dakota imposes no newspaper-publication requirement on a new LLC. The publication duty that founders read about belongs to a small set of states — New York, Arizona and Nebraska are the ones in this Atlas — and it does not travel with you if you form here.

Forms, office and processing

The filing office is the South Dakota Secretary of State, Business Services. The formation document is the Articles of Organization; most South Dakota filings can be made online, and online filings are acknowledged faster than paper ones as a rule. South Dakota's SOSEnterprise system processes online filings immediately; the Secretary of State's fee schedule also lists a $50 expedited service (checked 2026-11-05). (Processing source: the office’s own page — checked 2026-11-05.) What we commit to in writing, before anything is filed, is the fee, the duty and the due pattern on this sheet.

The foreign-registration warning

Forming in South Dakota does not licence you to operate everywhere. If your LLC will have an office, employees, inventory or a sustained physical presence in another state, that state will generally require foreign qualification there — a second registration, a second agent and a second set of duties, on top of this one. Non-residents most often trip on this by forming in a low-fee state while living-adjacent operations, warehousing or staff sit somewhere else. The state of formation should follow the business, not the other way round; the diagnostic on this site asks where your customers and operations are for exactly this reason.

Your registered agent in South Dakota

Registered agent must be a resident of South Dakota with BOTH a physical and a mailing address in South Dakota. Permitted types (SOS FAQ): a Noncommercial Registered Agent (an individual residing in SD, or a business entity registered in SD); a Commercial Registered Agent (registered with the SOS and paid the registration fee); the office-holder option does NOT apply to LLCs. Governed by SDCL Chapter 59-11.

Formation Complete includes the registered agent for year one. From year two the renewal is $149 a year — the same figure on every sheet in this Atlas, because the agent’s job (a real address, a person or service that can receive process, and forwarding that actually reaches a founder overseas) costs the same diligence in Pierre as anywhere else. If you move the agent elsewhere, the duty calendar below does not move with it: the report duty belongs to the LLC, not to the agent.

Duty calendar

Annual report — due in your anniversary month — $55 online.

Filled cell = a month in which this state’s duty falls due.

The recurring duty is the line that decides what South Dakota costs you in year three, not just year one. Annual report — due in your anniversary month — $55 online. Priced into the five-year table on this sheet at $55 a year (annualised), it is the difference between a cheap formation and a cheap company.

If it is late. $55 late fee for delinquent annual reports: the entity becomes delinquent if the report is not filed within 2 months following the due date (e.g., due June 1 → late fees begin August 1), and reports filed after the delinquency date incur the $55 late fee (SOS FAQ and fee schedule). The fee on this sheet is the online fee; paper filing is $70 including the $15 paper filing fee.

If the duty is missed altogether. If the entity remains in delinquent status it may be administratively dissolved (SOS FAQ: 'If the entity continues to stay in a delinquent status, it may be Administratively Dissolved'). Domestic LLC reinstatement is $150 plus delinquent reports and fees per the fee schedule.

Cost of ownership

Formation Complete $399 one-time + state fee at cost; agent renewal $149/yr from year 2; state duty annualised from the verified figure on this sheet.
Horizon	Total paid	What it contains
Year 1	$549	$399 package + $150 state fee; agent year 1 included
By end of year 2	$753	Year 1 + $149 agent renewal + $55 state duty
By end of year 5	$1,365	Year 1 + four renewals + four years of state duty

Compare that five-year figure, not the formation fee, against any other state you are considering — the compare tray in the Atlas does it side by side for up to three states. A state that is $100 cheaper to form and $300 a year heavier to keep is the expensive state.

Where South Dakota sits in this Atlas: 38th of 49 by formation fee ($150), and 31st by the five-year cost of ownership ($1,365). The year-one total of $549 is the $399 package with the state fee passed through at cost; after that, the meter runs at the $149 yearly agent renewal plus the state duty of $55 a year. The state duty itself makes up 16.1% of the five-year total; the rest is the package and the registered-agent renewal. That sits above the Atlas median five-year cost of $1,260. Judged on five years instead of filing day, South Dakota is a state whose keeping costs deserve a second look before you file — and that longer view is the one a non-resident owner actually lives with.

Non-resident specifics in South Dakota

South Dakota’s recurring state cost for a domestic LLC is the duty on this sheet — Annual report — due in your anniversary month — $55 online. Two cautions decide whether that stays the whole story. First, tax follows activity, not paperwork: if your customers, property or people are in another state, that state can require foreign qualification there and tax the activity there, whatever this sheet says. Second, an LLC is a state-law shell around a federal tax position: a foreign-owned single-member LLC is disregarded for federal income tax by default, which is exactly the status that carries the Form 5472 duty described in the non-resident section below — the state choice does not change it.

The federal layer, which no state choice removes. A single-member LLC owned by a non-resident is, by default, a disregarded entity for US federal income tax — and since 2017 that status carries an annual information duty: Form 5472 attached to a pro-forma Form 1120, due each year the LLC exists, reporting reportable transactions with its foreign owner (funding the company counts). The penalty for a missing or late Form 5472 starts at $25,000. Multi-member LLCs are taxed as partnerships by default and file Form 1065, with their own withholding questions when US-source income reaches foreign partners. None of this is a reason not to form; all of it is a reason to form with the calendar already drawn. The EIN guide on this site walks the Form SS-4 route for founders with no SSN or ITIN, the CP 575 you receive, and the 5472 duty in full.

Address and banking reality. Your South Dakota LLC’s address on the state record is its registered office — the agent’s address — which is a service address, not your trading address, and should never be sold to you as one. Banks and payment processors will ask for the beneficial owner’s foreign address and passport-grade identification, and many will ask why the company sits in South Dakota; “my operations and customers are there” is an answer, a fee table is not. Form where the answer is true.
