Enterprise LLCs Formed in South Dakota
| Entity Name | Why They Chose South Dakota |
|---|---|
| Citibank (South Dakota), N.A. Operating LLC | South Dakota eliminated its usury interest rate cap in 1980 — enabling national banks and their LLC subsidiaries to issue credit cards with no state-level APR ceiling. Citibank was the first major bank to relocate its credit card operations to South Dakota for this reason, establishing the model that all major US card issuers now follow. |
Why South Dakota attracts enterprise LLCs: South Dakota's elimination of interest rate caps in 1980 made it the US capital for credit card issuing — major banks (Citibank, Wells Fargo, Capital One) maintain South Dakota LLC subsidiaries for their national credit card portfolios. Combined with no state income tax, it remains a top choice for financial holding companies.
Entity examples are illustrative and based on publicly available corporate registrations. Reasons reflect general state-level legal and tax advantages — not verified statements of each company's formation rationale.
