How to Form an LLC
in South Dakota

South Dakota charges a $150 Articles of Organization filing fee for online submissions through the SD Secretary of State's online portal (sosenterprise.sd.gov), $165 if filed on paper by mail. Eleet AI charges $299 all-inclusive — that covers the $150 state fee, Articles of Organization preparation, filing through sosenterprise.sd.gov, and first-year SD registered agent service. National services commonly advertise SD formation packages at $0–$149 then add the $150 state fee, a mandatory registered agent ($125–$299/yr), and various upsells, pushing the realistic first-year total to $350–$600+. South Dakota's $150 filing fee sits in the middle of US filing fees — higher than MS $50 / NM $50 / CO $50 / MI $50 / AR $45 / KY $40 / MT $35, similar to OR $100 / WV $100 / NH $102 / ID $100 / NE $105 / KS $165, below CA $70 (+ $800/yr franchise) / NY $200 + $500–$2,000 publication / TX $300 / MA $500. What makes SD uniquely cost-effective is not the filing fee itself but the ongoing tax story — zero state individual income tax, zero state corporate income tax, no franchise tax on regular LLCs.

Yes — South Dakota requires a $50 Annual Report filed online ($65 if paper) under SDCL § 47-34A-209. The report is due by the first day of the second month following the LLC's formation anniversary month — not a fixed calendar date. If you formed June 15, your annual report is due by August 1 each year. If formed October 3, due December 1. Miss the deadline and the state imposes a $50 late fee; extended non-filing leads to administrative dissolution of the LLC. At $50/yr, SD's annual report is roughly mid-pack among US states — higher than MS $0 / OH $0 / NM $0 / MO $0 / AZ $0, lower than CA $800 / MA $500 / IL $75+ / NY's biennial $9 but with $500–$2,000+ publication cost year one / DE $300 / MD $300+. Eleet AI tracks your specific anniversary-based due date and sends a courtesy reminder 45 days before the deadline; optional $49 filing service covers the annual report preparation and submission on your behalf.

No — South Dakota is one of only eight US states with zero state individual income tax (AK, FL, NV, SD, TN, TX, WA — wages only, WY). Notably, New Hampshire's Interest & Dividends tax fully sunsets January 1, 2027 making it the ninth. More importantly for LLCs, South Dakota is also one of only THREE US states (SD, TX, WY) with zero state individual income tax AND zero state corporate income tax AND zero franchise tax on regular LLCs. Texas has a Franchise (margin) Tax at 0.375%–0.75% above $2.47M revenue threshold; Wyoming has a small $60 minimum license tax. South Dakota has no equivalent entity-level state tax on operating LLCs — the closest SD tax is the Bank Franchise Tax under SDCL 10-43, which applies ONLY to commercial banks and certain financial institutions (not to ordinary LLCs, not to holding LLCs, not to real-estate LLCs, not to trading LLCs, not to professional-services LLCs). For a Sioux Falls profit-making LLC earning $500K pre-tax, combined SD state income + franchise tax burden = $0. The same LLC in California would owe $800 minimum franchise tax + up to 13.3% on personally-flowed income; in New York, $500+ publication plus progressive state + NYC tax; in Minnesota, 9.85% top rate. SD's zero-tax environment is the primary reason the state punches far above its 900K population in financial-services + trust-company concentration.

South Dakota has been consistently ranked the #1 US trust jurisdiction by Trusts & Estates magazine for over a decade, ahead of Delaware, Nevada, Alaska, and Wyoming. Five SD-specific statutory advantages drive this ranking: (1) NO rule against perpetuities — South Dakota abolished the common-law Rule Against Perpetuities in 1983 under SDCL § 43-5-8, allowing perpetual "dynasty trusts" that pass wealth tax-efficiently across unlimited generations with no forced distribution deadline. Delaware permits 110-year perpetuity; Nevada 365 years; South Dakota is one of only a handful of true unlimited-perpetuity states. (2) Domestic Asset Protection Trust (DAPT) under SDCL Chapter 55-16 (enacted 2005, strengthened 2007 + 2014 + 2018) — self-settled spendthrift trust where the settlor can also be a beneficiary, with creditor protection after a 2-year statute of limitations (versus Alaska's 4-year, Nevada's 2-year, Delaware's 4-year). (3) Directed trusts under SDCL Chapter 55-1B — family wealth can bifurcate investment + distribution + administrative trustees across multiple parties, letting families retain investment control while leveraging SD's tax + privacy benefits. (4) Total trust litigation sealing under SDCL § 21-22-28 — South Dakota is the only US state with a statute that automatically seals all trust litigation court filings + proceedings + dockets from public view, PERMANENTLY and BY DEFAULT, unlike Delaware/Nevada where sealing requires a court motion. (5) No state income tax on trusts with non-resident beneficiaries. Combined, these features have attracted an estimated $500B+ in assets under administration at SD trust companies — major trust-company headquarters include South Dakota Trust Company, Bridgeford Trust, Argent Trust, First Interstate, and many family offices of billionaire dynasties (Walton, Pritzker, and other well-known families have used SD trust structures). For LLC founders considering asset-protection planning, SD is where the serious wealth goes.

Sioux Falls is the largest concentration of consumer credit card operations in the United States — larger than New York, Wilmington, Charlotte, or Atlanta. The story starts with SB 8 (1981), signed by Governor William Janklow, which completely repealed South Dakota's state usury cap on consumer interest rates. In the same year, Citibank's New York credit card division was trapped by New York State's 12% usury ceiling while the Federal Reserve's anti-inflation rate hikes had pushed the bank's cost-of-funds above 20%. Citibank's CEO Walter Wriston negotiated with Governor Janklow to move Citibank's consumer credit card operations from New York to Sioux Falls in exchange for SD passing SB 8. The move brought ~3,000 jobs initially and, combined with the US Supreme Court's Marquette Nat'l Bank v. First of Omaha Service Corp (439 U.S. 299, 1978) ruling that the home-state usury ceiling of a national bank applies to cardholders nationwide, effectively gave Citibank (and other national issuers that subsequently moved to SD or DE) the ability to charge any interest rate permitted by their home state to any customer anywhere. The result: today Sioux Falls hosts Citigroup Cards, Wells Fargo (SD's largest private employer), Capital One Bank (USA) NA, First Premier Bank + Premier Bankcard (Denny Sanford — largest US subprime credit card issuer, SD's only billionaire-founded private bank), MetaBank/Pathward (prepaid cards + EIP disbursements), and several other national bank subsidiaries. South Dakota's no-usury-cap + no-state-income-tax environment makes it one of two preferred home states for national credit card issuers (alongside Delaware), and the supplier + services + legal ecosystem around Sioux Falls banking is the largest sector of the SD economy outside agriculture.

Yes. South Dakota imposes a 4.2% state sales tax under SDCL Chapter 10-45 on retail sales of tangible personal property and certain services. HB 1137 (2023) temporarily reduced the rate from 4.5% to 4.2% with a scheduled sunset back to 4.5% on July 1, 2027 (absent further legislative action). Municipalities may impose up to 2% additional local sales tax under SDCL § 10-52 — combined rates range from 4.2% in unincorporated territory up to 6.2% in the highest-tax cities (Sioux Falls 6.2%, Rapid City 6.2%, Aberdeen 6.2%, Watertown 6.2%, Pierre 6.2%). South Dakota's 4.2%–6.2% combined sales tax is below the US average (~7%) and well below CA ~8.8% / IL ~8.8% / TX ~8.2% / NY ~8.5% / AR ~9.5% — but above the zero-sales-tax states AK / DE / MT / NH / OR. Economic nexus threshold under SDCL § 10-45-2 (post South Dakota v. Wayfair, 138 S. Ct. 2080, 2018) is $100,000 in SD-source sales per calendar year (the 200-transaction threshold was REPEALED in 2023 under HB 1002, making SD the first state to drop the transaction count after Wayfair — now $100K revenue only). Notably, South Dakota v. Wayfair is the landmark US Supreme Court case that established state authority to require remote sellers to collect sales tax, originating from South Dakota's own economic nexus statute.

South Dakota imposes a 2% Contractor's Excise Tax under SDCL Chapter 10-46A on the gross receipts of prime contractors for construction services in the state. This is unique to SD — most states apply sales tax to construction materials at the supplier level but not a separate contractor-side gross-receipts tax. Under SDCL § 10-46A-1, "prime contractor" means anyone who enters a construction contract with an owner (residential, commercial, public infrastructure). The 2% excise tax applies on top of the 4.2% state sales tax + local sales tax on materials, so a construction LLC in Sioux Falls effectively pays 4.2% + 2% local + 2% excise = ~8.2% cumulative tax burden on contract value. Contractor's Excise Tax is NOT creditable against state or local sales tax — it is an independent gross-receipts tax stacked on top. Honest framing most competitor SD LLC guides skip: if your LLC is a construction contractor (general contracting, roofing, HVAC, plumbing, electrical, drywall, framing, excavation, concrete, landscaping construction, fencing construction), you must register for Contractor's Excise Tax with the SD Department of Revenue and collect + remit 2% on every contract. If your LLC is a DOWNSTREAM service company (project management consulting, architectural design without construction execution, engineering services, real-estate brokerage, facilities management, cleaning services), you do NOT owe Contractor's Excise Tax — you're in the normal sales + use tax pool. Pure non-construction LLCs (consulting, e-commerce, SaaS, real-estate holding, retail, professional services) have zero Contractor's Excise Tax exposure.

Standard online processing through the SD Secretary of State's online portal at sosenterprise.sd.gov is typically 1–2 business days. Paper filings mailed to the Pierre SOS office take 5–10 business days once received. South Dakota does NOT offer a paid expedited tier — the standard 1–2 business-day online processing is already among the fastest in the US (comparable to IA same-day, AR 1–3 days, OR same-day, CO 1–2 days, ID 1 day), so no expedite upcharge is needed. For most founders, the online standard processing is fast enough to handle bank-account-opening or contract-signing deadlines without needing to pay for speed. Eleet AI's standard SD filing submits through sosenterprise.sd.gov and typically delivers filed Articles of Organization within 1–2 business days.

Yes. Under SDCL § 47-34A-108 (Chapter 47-34A, South Dakota Uniform LLC Act), every SD LLC must designate and continuously maintain a registered agent with a physical South Dakota street address — no P.O. boxes, no private mailbox services, no virtual-office-only addresses. The agent must be available during normal business hours to accept service of process and official state correspondence. South Dakota uses standard "registered agent" terminology (not "resident agent" like MI/MD/MA, or "statutory agent" like AZ/OH). You can serve as your own registered agent only if you personally have an SD street address. If you do not live in South Dakota, you MUST use a commercial registered agent. Commercial registered agent services typically cost $100–$299 per year when purchased separately. Eleet AI includes first-year South Dakota registered agent service free with every SD LLC formation, then $100/yr after — the same flat rate we charge in all 50 states.

This three-way comparison comes up often because SD/WY/DE are the three most sophisticated US LLC jurisdictions for holding companies, trusts, and asset-protection vehicles. Honest comparison: (1) Filing cost: DE $110 / SD $150 / WY $100 — WY wins. (2) Annual fee: DE $300 franchise tax (regardless of activity) + $50 registered agent / SD $50 annual report / WY $60 minimum annual license — SD and WY tied, DE highest. (3) State income tax on LLC pass-through income: DE none (residents owe DE personal tax 2.2–6.6% on their K-1 share) / SD zero / WY zero. (4) Franchise tax: DE $300/yr flat regardless of activity / SD zero on regular LLCs / WY zero on regular LLCs. (5) Publication: none in any of the three. (6) Member anonymity: DE permits anonymous Certificate of Formation (no member/manager disclosure) / SD requires one organizer name on Articles but NOT members/managers, annual report lists manager(s) for manager-managed LLCs but not passive members / WY anonymous Articles and Annual Report member/manager disclosure requirements narrower than SD. WY slightly stronger anonymity than SD, DE slightly stronger than WY. (7) Case law depth: Delaware is #1 globally — the Court of Chancery is the gold-standard commercial court with the deepest body of LLC law precedent / WY has strong charging-order-exclusive case law (Wyoming's W.S. 17-29-503 has been cited in multiple federal and state appeals) / SD has less tested case law but stronger DAPT and perpetuity statutes than either. (8) Dynasty trust + DAPT: SD wins decisively — no rule against perpetuities (DE 110 years, WY 1,000 years), SDCL 55-16 DAPT with 2-year SOL, SDCL 21-22-28 automatic trust-litigation sealing. (9) VC / institutional funding readiness: DE wins — every US VC expects DE C-Corp or DE LLC, not SD or WY. Summary: VC-backed startups → DE. Operating businesses where owners want the best overall tax + privacy environment with reasonable asset protection → SD or WY (SD wins for estate + trust planning, WY for operating-company simplicity). Single-member LLC asset protection with strong charging-order remedy → WY. Family-office / generational wealth / dynasty trust → SD by a wide margin.

Partially. Under SDCL § 47-34A-203, the Articles of Organization filed with the Secretary of State require only the organizer name + signature, registered agent name + SD address, principal office address, and management structure designation (member-managed or manager-managed) — members and managers are NOT required on Articles of Organization themselves. The Annual Report under § 47-34A-209 requires the registered agent + principal office address update each year and, for manager-managed LLCs, a list of managers of record (not members). For member-managed LLCs, the Annual Report requires a list of members (SD is stricter than WY or DE here — WY requires no member or manager disclosure on its Annual Report, DE requires no member or manager disclosure on its Certificate of Formation or annual franchise tax filing). Strategy note: forming as a manager-managed LLC and naming a nominee manager (the trust company or RA firm acts as manager-of-record) is the standard pattern for founders wanting SD privacy without sacrificing member anonymity. This is NOT a public-record-anonymity play like Wyoming or New Mexico — SD privacy is better achieved in the trust layer (SDCL 21-22-28 total trust litigation sealing, best in the US) than in the LLC-formation layer. For pure LLC anonymity, Wyoming or New Mexico is stronger. Federal Beneficial Ownership Information (BOI) reporting with FinCEN applies to all US LLCs regardless of state-level anonymity.
