South Dakota LLC vs Oklahoma LLC (2026)
Written for owners based in South Dakota.
Verdict: for most owners, form where the business is based
Oklahoma is cheaper on both counts, $100 to file and a $25 Annual Certificate each anniversary, against $150 and $55 in South Dakota. Two details are easy to miss. The only reminder Oklahoma sends goes to the LLC's last known email address, and 60 days after a missed certificate the company loses good standing, cannot file anything and cannot maintain a lawsuit in an Oklahoma court. Card payments add 4%. South Dakota's $750 admission fee dwarfs the $80 Oklahoma saves you.

Compare LLC Costs: South Dakota vs Oklahoma
South Dakota
Oklahoma
A figure shown as "from" is the least the state can charge, not a price. Tennessee's report is $300 for up to six members and $50 for each member above six, its franchise tax is the greater of $100 or 0.25% of Tennessee net worth, Wyoming's report is the greater of $60 or $.0002 per dollar of in-state assets, Kentucky's entity tax is $175 up to $3 million of gross receipts and graduated above it, and New York's annual filing fee is graduated on New York source gross income. A total that contains one of those is shown as "from" for the same reason. Costs include every mandatory state charge: the filing fee, the report fee (annualised where a state files biennially), any state entity-level tax shown in its own row above, a one-time publication cost where the state publishes a rate for it, and any one-time registration charge a state requires before the LLC may trade. Two exclusions follow from that wording. Arizona and Nebraska require publication and publish no rate, so no newspaper cost is carried for either and their totals are not the whole cost. Alaska's $50 annual state business licence is a separate charge from the Secretary of State fees and is not carried here either. Annualising makes the 1, 3 and 5 year rows a cost of ownership rather than a payment schedule: a biennial state charges its whole report fee in the years it falls due and nothing in between. Entity-level taxes that only apply after a corporate election, or above an owner or income threshold, are excluded and flagged on the state's own cost page. New York's publication cost is carried at a $250 floor, roughly $200 of newspaper cost in a low-cost county plus the $50 Certificate of Publication fee. No county-clerk-designated New York City newspaper publishes a rate card, so the four-figure NYC estimates in wide circulation cannot be traced to a primary source and are not asserted here; budget for materially more than the floor if you file in a NYC county. Every fee was verified against the state's own fee schedule, statute, or revenue authority on 29 July 2026. Excludes registered agent and legal fees.

Filing Fees & Formation Costs
South Dakota charges $150 to form an LLC, while Oklahoma charges $100. Oklahoma is $50 cheaper upfront. The cost that usually gets overlooked: if you form in Oklahoma but operate in South Dakota, you must also register as a foreign LLC in South Dakota (a $750 filing) and maintain a registered agent in Oklahoma (typically around $150 per year). That puts the realistic first-year cost of the Oklahoma route at roughly $1,000, versus $150 for simply forming in South Dakota. Speed isn't a basis for choosing between them: neither South Dakota nor Oklahoma publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: South Dakota vs Oklahoma
South Dakota has no personal income tax, while Oklahoma taxes individual income. Since pass-through LLC profits are taxed where you live and operate, a South Dakota-based owner keeps South Dakota's no-income-tax benefit either way. Forming in Oklahoma adds no tax advantage. Neither state imposes a separate franchise or privilege tax on LLCs beyond standard filing fees.
Privacy & Asset Protection
Neither South Dakota nor Oklahoma offers anonymous LLC formation: both states require owner or manager information on public filings. Oklahoma's registration and annual certificate identify a member, manager, or authorized signer on the public record. Business owners who prioritize privacy typically form a holding company in a state like Wyoming or New Mexico instead. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal.
Annual Maintenance Costs
South Dakota LLCs file an annual report ($55, due in the anniversary month), and Oklahoma LLCs file an annual report ($25, due in the anniversary month). If you form in Oklahoma while operating in South Dakota, you maintain filings in both states, Oklahoma's report plus South Dakota's equivalent for your foreign registration, and pay an Oklahoma registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Oklahoma route to roughly $230 a year, versus about $55 to keep a domestic South Dakota LLC in good standing.
When Oklahoma Actually Makes Sense
Forming in Oklahoma makes sense in a few specific situations: your business genuinely operates in Oklahoma, with a real office, employees, or property there, or you're relocating to Oklahoma in the near future and accept taking on Oklahoma's personal income tax, which South Dakota doesn't levy. For a typical small business based in South Dakota, none of these usually apply. Registering an Oklahoma LLC to do business back home means $750 in South Dakota foreign-registration fees, on top of Oklahoma's $100 formation fee, while South Dakota's own annual report runs $55 a year and is due in the anniversary month. When in doubt, form where you actually do business.
