A South Dakota LLC costs $447 all-in through Anonymousllc.co in year one: a $297 service fee plus the $150 state filing fee, covering filing, registered agent, operating agreement, EIN, and bank applications. Ongoing cost is $150/year: the $50 annual report plus $100 for registered agent service. South Dakota charges no state income tax and no franchise tax on the LLC. This page breaks down every South Dakota LLC cost for 2026 and compares it against the anonymous-LLC states.
The South Dakota Secretary of State charges a $150 filing fee for the Articles of Organization, paid once at formation. This is the only mandatory state fee due at filing time. The fee is the same for single-member and multi-member LLCs and for resident and non-resident owners. Filing clears in 1-3 business days. A separate name reservation is available for founders who want to hold a name before filing, but standard formation does not require it, so most owners pay only the $150. Payment is made to the South Dakota Secretary of State at submission, and the filing fee is non-refundable once the Articles are processed. This is why the name check matters before filing: a rejected name after payment means the fee is already spent. Anonymousllc.co clears the name and prepares backups before it submits, so the $150 buys an accepted filing on the first pass.
Ongoing South Dakota costs are the $50 annual report plus $100/year for registered agent service, for $150/year in total maintenance. There is no state personal income tax and no Delaware-style franchise tax on the LLC itself. The annual report keeps the LLC in good standing and updates the registered agent and principal office on the public record. Skipping it leads to delinquent status and eventual administrative dissolution. Anonymousllc.co bundles annual-report filing into the registered agent subscription, so the $150/year covers both the agent and the report submission.
Filing yourself costs only the $150 state fee, but you handle the name check, operating agreement, EIN application, and bank applications alone. Anonymousllc.co charges a $297 service fee on top of the state fee and completes everything in 5-10 business days. The DIY route saves the $297 in cash but costs time and carries risk on the steps most owners have never done: a fax-filed EIN for non-residents, a compliant operating agreement, and multi-bank applications. The service route delivers a stamped filing, an EIN, an operating agreement, and four to five bank applications as one package.
Anonymousllc.co forms a South Dakota LLC for $447 all-in: a $297 service fee plus the $150 state fee. That price includes filing, registered agent year one, operating agreement, EIN, and four to five US bank applications with Mercury, Relay, and Bluevine. Add-on services are priced separately: EIN $99, ITIN $299, and BOI filing $150 when applicable. Founders who want ownership privacy instead form a Wyoming anonymous LLC at $397 all-in and foreign-qualify into South Dakota when local operations require it. There are no hidden upsells behind the $447 number.
For total 2026 cost, New Mexico is the cheapest at $347 with Anonymousllc.co and requires no annual report. Wyoming is second at $397 all-in with strong ownership privacy. A South Dakota LLC runs $447 in year one plus $150/year maintenance. The gap is more than price. New Mexico and Wyoming keep members and managers off the public record; South Dakota does not. A founder who wants both low cost and privacy forms a New Mexico or Wyoming anonymous LLC and foreign-qualifies into South Dakota when the business has a physical South Dakota presence.
Reinstating an administratively dissolved South Dakota LLC costs $250 plus state fees through Anonymousllc.co, handled case by case. Reinstatement requires filing the back annual reports, paying the accrued penalties, and submitting a reinstatement application. The cheaper path is to never miss the $50 annual report in the first place. Anonymousllc.co tracks the deadline as part of the $100/year registered agent service and files on the owner's behalf, which keeps the LLC in good standing and avoids the reinstatement cost entirely.
No. The South Dakota LLC cost is the same for non-residents: $447 all-in with Anonymousllc.co. Non-residents pay no citizenship surcharge and the $150 state fee does not change. The one extra cost some non-residents choose is an ITIN at $299, needed for personal US tax filing rather than for the LLC itself. The EIN is obtained by fax at no extra charge inside the formation package. Banking is handled remotely, so there is no travel cost to open the US account.
South Dakota charges no state personal income tax, so state tax adds nothing to the annual cost of holding the LLC. The only recurring state charge is the $50 annual report. Federal tax still applies as a pass-through: profit flows to the owners' returns rather than being taxed at the entity level. Owners with net income above $40,000-$60,000 can elect S-corp treatment to reduce self-employment tax, which lowers total tax cost but adds payroll compliance. The zero state income tax is the main cost advantage of a South Dakota LLC for in-state owners.
The privacy path costs $397 all-in for a Wyoming anonymous LLC or $347 for a New Mexico anonymous LLC, compared with $447 for a domestic South Dakota LLC. All three include the $297 service fee plus each state's filing fee. When a founder wants privacy and also has a physical South Dakota presence, the total combines the anonymous LLC with a South Dakota foreign qualification, which adds the South Dakota state qualification fee and the $50 annual report. Ongoing cost for the anonymous parent is $100/year for the registered agent, plus New Mexico's zero annual report or Wyoming's $60 report. Anonymousllc.co quotes the combined structure as one price so the founder sees the full cost before filing.
A South Dakota LLC costs more upfront because its state filing fee is $150, against $100 in Wyoming and $50 in New Mexico. The $297 Anonymousllc.co service fee is identical across all three states, so the gap is the state fee alone. At formation that puts South Dakota at $447 all-in, Wyoming at $397, and New Mexico at $347. The ongoing picture widens the gap: South Dakota charges a $50 annual report, Wyoming a $60 report, and New Mexico none at all. None of the three levies a state income tax or a franchise tax on the LLC, so the difference is filing and annual-report fees rather than tax. A founder choosing on price alone lands on New Mexico; a founder who needs a physical South Dakota presence pays the $150 state fee to form there.
An EIN for a South Dakota LLC costs nothing when it is obtained inside the Anonymousllc.co formation package, and $99 as a standalone add-on for an owner who already holds an LLC. The IRS itself charges no fee to issue an EIN. US-resident owners get the EIN online in minutes; non-resident owners without an SSN receive it in 5-7 days by fax filing IRS Form SS-4, with Anonymousllc.co acting as third-party designee. A non-resident who also needs a personal US tax ID buys an ITIN at $299, a separate number for individual filing rather than for the LLC. Neither the EIN nor its fax handling adds to the $447 all-in formation price; the $99 applies only when the EIN is purchased on its own.
