South Dakota LLC Cost: $150 Filing + $55 Annual Report (2026)

Forming an LLC in South Dakota costs $150 to file Articles of Organization with the Secretary of State, then $55/yr for the annual report. No state income tax. No franchise tax for non-financial LLCs. No publication requirement. Five-year total: $370 (DIY). South Dakota’s structural advantage is not the headline filing fee, it is the combination of no income tax, the country’s strongest dynasty-trust laws, and well-developed charging-order protection that makes the state a quiet competitor to Wyoming and Nevada for asset-protection LLCs.

TL;DR

South Dakota charges $150 to file Articles of Organization with the Secretary of State (online filings are $150 flat; mail filings are $165). The annual report is $50 online or $65 by mail (the $55 figure used by most calculators reflects the online filing average across years). No state income tax. No personal income tax. No corporate franchise tax for non-financial LLCs. The state’s LLC statute (SDCL Chapter 47-34A) tracks the Revised Uniform Limited Liability Company Act and includes strong charging-order protection for both single-member and multi-member LLCs. Combined with South Dakota’s nation-leading dynasty-trust regime (no rule against perpetuities), the state has become a quiet asset-protection hub for high-net-worth founders, particularly those pairing an SD LLC with an SD trust.

Why South Dakota stands out

South Dakota’s filing fee ($150) is mid-pack nationally. The state’s appeal is structural: zero state-level income tax on individuals or pass-through entities, paired with statutory features that make it a serious asset-protection jurisdiction even before founders combine the LLC with an SD trust.

• No state personal income tax. Pass-through LLC earnings flow only to the federal return. SD is one of nine states with no individual income tax (alongside Wyoming, Texas, Florida, Tennessee, Washington, Nevada, Alaska, and New Hampshire on wages).
• No corporate franchise tax for non-financial LLCs. Banks and other financial institutions face a separate franchise tax; ordinary LLCs do not.
• Charging-order-only protection. SDCL § 47-34A-503 makes the charging order the exclusive remedy for a creditor against an LLC member’s interest, protecting against forced liquidation. SD applies this rule to single-member LLCs too, matching Wyoming and Nevada.
• No rule against perpetuities. South Dakota abolished the rule against perpetuities in 1983, making it the only state where dynasty trusts can hold LLC interests indefinitely. The SD LLC + SD trust pairing is a well-known asset-protection structure.
• Anonymous-friendly filings. Member names are not required on public Articles of Organization. Only the organizer and registered agent appear on the public record.
• Same-business-day processing. Online filings are typically approved within hours, no separate expedite fee.

The single requirement non-residents cannot avoid: a South Dakota resident agent with a physical SD street address.

Filing steps (DIY, no service)

1. Pick a name, search availability at the SD SOS business name search. Names must include “Limited Liability Company,” “LLC,” or “L.L.C.”
2. Designate a registered agent, must be a South Dakota resident individual or business entity, with a physical SD street address.
3. File Articles of Organization, $150 online or $165 by mail. File at the SD SOS business filings portal or by mail to South Dakota Secretary of State, 500 East Capitol Avenue, Pierre, SD 57501.
4. Get a federal EIN, free at irs.gov.
5. Draft an operating agreement, not required by SD statute but standard practice. SDCL § 47-34A-110 recognizes oral, written, or implied operating agreements.
6. Open a business bank account, First Bank & Trust, First Premier Bank, and most local credit unions accept SD LLC filings; SD also hosts several private trust companies that work with anonymous LLCs.
7. Register for sales tax, if selling taxable goods, get a Sales Tax License (free) from the SD Department of Revenue.
8. Register for any required local taxes, certain SD cities (Sioux Falls, Rapid City) levy local sales taxes; verify with the city’s finance department.
9. File FinCEN BOI report, required under the Corporate Transparency Act within 30 days of formation. Free to self-file at fincen.gov/boi. Non-public.
10. Calendar the annual report, due in the LLC’s anniversary month each year, $50 online.

Online filings via the SD SOS portal are typically processed same business day. There is no separate expedited filing fee.

Hidden costs founders miss

Beyond the $150 + $50/yr math, four costs commonly catch SD founders by surprise. First, the registered agent service. Out-of-state founders typically need to hire a commercial RA at $50-$200/yr; SD’s smaller market means RA service options are fewer than in Wyoming or Delaware. Second, the federal FinCEN BOI filing, free at fincen.gov/boi but a compliance step that triggers $500/day federal penalties if missed within the 30-day post-formation window. Third, sales tax compliance. South Dakota’s 4.5% state sales tax plus variable municipal taxes (1%-2% in major cities) applies to retail sales, and SD was the lead plaintiff in the Wayfair Supreme Court decision establishing economic-nexus rules, meaning out-of-state e-commerce sellers with $100,000+ in SD sales must register and collect SD sales tax. Fourth, the dynasty-trust pairing legal costs. If you are forming an SD LLC specifically to pair with an SD trust, attorney fees for the trust drafting typically run $5,000-$20,000+ depending on complexity and trust company involvement.

Page-unique facts

• South Dakota has no rule against perpetuities. Repealed in 1983 by SDCL § 43-5-8, this makes SD the leading state for dynasty trusts. Founders frequently form an SD LLC and an SD dynasty trust together for multi-generational wealth-holding structures.
• Charging-order-only protection for single-member LLCs. SDCL § 47-34A-503 explicitly extends exclusive-remedy charging-order protection to single-member LLCs, joining Wyoming, Nevada, Delaware, and Alaska in this top tier.
• No state income tax, individual or corporate. Combined with no franchise tax on non-financial LLCs, this gives SD one of the cleanest entity-level tax profiles in the country.
• South Dakota holds approximately $700 billion in trust assets. The combination of dynasty-trust law, asset-protection trust law (SDCL Chapter 55-16), and LLC-friendly structure has made SD the largest trust jurisdiction in the US by some measures, ahead of Delaware in trust assets under management.
• Member names are not on public Articles. Only the organizer (often an RA service) and the registered agent appear on the public filing.

FAQ

Is South Dakota a good state for asset protection?

Yes, and for specific reasons. SDCL § 47-34A-503 establishes charging-order-only creditor remedy for both single-member and multi-member LLCs, on par with Wyoming and Nevada. SD also has no rule against perpetuities (SDCL § 43-5-8) and a robust asset-protection trust statute (SDCL Chapter 55-16). The SD LLC + SD dynasty trust pairing is one of the strongest legal asset-protection structures available in the US for high-net-worth families. Source: SD Codified Laws Title 47.

Does South Dakota have a state income tax?

No. South Dakota is one of nine states with no personal income tax, and there is no corporate income tax or franchise tax for non-financial LLCs. Pass-through LLC profits flow only to the federal return. Sales tax (4.5% state + variable local) applies to taxable transactions. Source: SD Department of Revenue.

Can a non-SD resident form a South Dakota LLC?

Yes. SD has no residency requirement for members or managers, only the registered agent must have a physical SD street address. Non-residents typically use a commercial RA service ($50-$200/yr). For non-residents with no SD operations, the LLC owes no SD-level income tax, the structure is most useful for holding assets, IP, or trust beneficiary interests rather than active operations.

Why do trust companies use South Dakota?

South Dakota repealed the rule against perpetuities in 1983, making it the first US state where dynasty trusts can hold assets indefinitely without forced distribution at any future date. Combined with no state income tax, no rule against accumulation, and strong creditor-protection statutes, SD has become the home jurisdiction for hundreds of private trust companies managing roughly $700 billion in assets. Founders pairing an LLC with a long-horizon estate plan use SD for both entities. Source: SDCL § 43-5-8.

Does South Dakota recognize Series LLCs?

Yes. SDCL § 47-34A-1001 et seq. authorizes Series LLCs. A single $150 filing creates a “master” LLC with multiple internal series, each holding separate assets and liabilities. Common pattern for real-estate investors holding multiple SD properties or for asset-protection structures pairing each series with a separate trust beneficiary.

What is the annual report deadline?

The South Dakota annual report is due in the first day of the LLC’s anniversary month each year. The Secretary of State sends an electronic reminder, but the legal obligation runs whether or not the reminder arrives. Online filing is $50; mail filing is $65. Failure to file within 60 days of the due date results in an LLC’s administrative dissolution, with reinstatement fees of $150 plus all back-due reports.

State quirk: the LLC + dynasty trust pairing

South Dakota’s quiet competitive moat is not its $150 LLC filing fee, it is the combination of three statutes that almost no other state has assembled together. First, SDCL § 43-5-8 (1983) abolished the rule against perpetuities, allowing trusts to hold assets indefinitely. Second, SDCL Chapter 55-16 (the South Dakota Domestic Asset Protection Trust statute) lets settlors place assets in a self-settled trust with creditor protection after a two-year seasoning period. Third, SDCL § 47-34A-503 makes the charging order the exclusive creditor remedy against an LLC member’s interest, including single-member LLCs. Stack these together and a founder can form an SD LLC, transfer membership interests to an SD dynasty trust, and after the seasoning period have an asset-protection structure that no other US state can fully replicate. This is why South Dakota holds disproportionate trust assets relative to its population. Cross-reference: South Dakota Codified Laws Title 55 (Trusts).

Common mistake in South Dakota

The most common South Dakota LLC mistake among non-residents is forming the LLC for asset-protection benefits but continuing to operate the underlying business in a high-tax home state without proper foreign-qualification or operating-agreement separation. If a non-resident founder operates a California business through an SD LLC, California still asserts nexus, requires foreign qualification, and charges the $800 franchise tax. The SD asset-protection benefits accrue when the LLC actually holds passive assets in SD or is paired with an SD trust, not when it is a shell over an out-of-state operating company.

A second common mistake is missing the annual report deadline. The SD report is due in the LLC’s anniversary month, not on a fixed calendar date, which is easy to forget when managing multiple entities. Failure to file within 60 days of the due date results in administrative dissolution. Reinstatement requires $150 in fees plus all back-due reports and any accrued tax obligations, expensive enough that founders who let one year slip often abandon the LLC and form a new one, losing the original formation date and any veil-piercing seasoning value.

A third mistake involves the SD LLC + dynasty trust pairing without proper sequencing. Founders who form the SD LLC and immediately transfer membership interests to an SD dynasty trust before the LLC has any economic substance can trigger fraudulent-transfer claims if a creditor surfaces within the trust’s seasoning window (2 years under SDCL Chapter 55-16). The proper sequence is to form the LLC, operate it for a meaningful period, build a normal business or investment history, then transfer interests to the trust well in advance of any anticipated creditor claim. Trust attorneys typically recommend at least 2-4 years of operating history before the transfer to establish that the LLC is a legitimate entity, not a sham conveyance.

Compared to other no-income-tax states

South Dakota’s $370 five-year cost lands roughly in the middle of the no-income-tax cluster. Wyoming is cheaper at $340 with the same charging-order-only protection and stronger anonymity statutes. Florida charges $125 to form and $138.75/yr annual reports, five-year total $680. Nevada charges $425 first-year (Articles + initial list + state business license) plus $350/yr in renewal fees, five-year total roughly $1,825, expensive by comparison. Texas is $300 once with $0 ongoing for LLCs under the $1.23M franchise tax threshold, structurally cheapest if you have actual TX nexus. Tennessee, despite no personal income tax, charges $300 + $300/yr + entity-level franchise/excise taxes, making it the most expensive of the no-income-tax states. For asset-protection-driven formations specifically, SD’s combination with the dynasty-trust regime is unique; for pure cost minimization, Wyoming and Florida usually win.

When South Dakota actually makes sense

South Dakota is a niche-purpose LLC state. It is not the cheapest (Wyoming, New Mexico, Utah, Ohio, and Missouri all beat it on baseline cost), and it is not the most prestigious for VC formations (Delaware dominates that lane). SD makes sense in four specific scenarios. First, for SD residents running SD-based businesses, the no-income-tax + no-franchise-tax structure is structurally efficient. Second, for non-residents pairing the LLC with an SD dynasty trust or asset-protection trust, the SD LLC + SD trust pairing leverages SD’s no-rule-against-perpetuities statute and charging-order-only protection. Third, for real-estate investors holding SD properties, the Series LLC option and absence of state income tax on rental income can be valuable. Fourth, for high-net-worth founders who already have advisors familiar with SD’s trust regime, the LLC adds a layer of charging-order protection that complements the trust structure. Outside these scenarios, Wyoming usually offers the same charging-order protection at lower cost.
