Compare taxes and see how much you save moving from South Dakota to Delaware
South Dakota and Delaware represent two distinct philosophies of business incorporation in the United States, each dominant in its own use case. South Dakota: the absolute zero-tax state, increasingly recognised as the best US jurisdiction for trusts, LLCs, holding companies, and asset protection structures. South Dakota has no personal income tax, no corporate income tax, no franchise tax on business entities, and the Revised Uniform Limited Liability Company Act (RULLCA) provides strong charging order protection. For high-net-worth individuals, family offices, and businesses structuring holding companies, South Dakota is often superior to Delaware. Delaware: the gold standard for venture capital-backed startups. The Delaware C-corporation is the near-universal choice for companies raising institutional VC, due to the Delaware Court of Chancery's body of corporate law, investor familiarity with Delaware preferred stock provisions, and attorney ecosystem expertise. Delaware does not tax out-of-state income, making it usable from anywhere. However, Delaware's annual franchise tax on C-corporations can be significant: companies with large numbers of authorized shares (common for equity-heavy startups) can face $50,000–$200,000+ in annual franchise tax under the default calculation method. For operating businesses, the choice often comes down to purpose: South Dakota for holding structures, trusts, and operating entities without institutional investors; Delaware for startups on the institutional investment path.
No Income Tax, No Corporate Tax, No Franchise Tax
Zero personal income tax; zero corporate income tax; zero franchise tax; minimal annual LLC report fee; leading state for trust and holding company structures
Investor Standard, Annual Franchise Tax
No income tax on out-of-state income for Delaware companies; annual LLC tax $300; C-corp franchise tax from $175 to $200,000+/year depending on authorized shares; gold standard for VC-backed companies
At Annual entity costs income:
South Dakota LLC annual cost: ~$50 report fee. Delaware LLC: $300 annual tax + $50 report = $350/year. C-corp comparison is more significant: SD charges no franchise tax; Delaware charges $175–$200,000+ depending on authorized shares. For trusts: South Dakota's perpetual dynasty trust laws have no equivalent in Delaware.

Get Matched With a Small Business Tax CPA →South Dakota has enacted some of the most powerful trust laws in the United States, making it the top choice for high-net-worth dynasty trust planning. Key features: (1) No rule against perpetuities — trusts can last forever; (2) Directed Trust Act — allows separation of investment management from trust administration, and trustee direction by a trust protector; (3) Decanting — allows irrevocable trusts to be modified by pouring assets into a new trust; (4) Total return unitrust — allows trustees to pay a percentage of trust assets rather than income only; (5) No South Dakota income tax on trust income; (6) Asset protection from creditors for self-settled trusts. South Dakota competes with Nevada and Alaska for dynasty trust business, with most practitioners ranking SD #1 or #2.
For a bootstrapped service business with no plans to raise institutional VC: South Dakota wins on cost and simplicity — no franchise tax, $50/year report fee, strong asset protection. You'll need to register as a foreign entity in your home state regardless. For a startup planning to raise seed or Series A+ institutional venture capital: Delaware C-corp remains the standard and you should not fight this. The conversion cost, attorney fees, and investor friction of converting from a South Dakota entity to Delaware C-corp will exceed any franchise tax savings. For holding companies, family LLCs, and trust structures: South Dakota is frequently the superior choice over Delaware.
Delaware calculates C-corp franchise tax using either the Authorized Shares Method or the Assumed Par Value Capital (APVC) Method — and uses whichever is higher on the initial bill. Under the Authorized Shares Method: 10 million authorized shares generates approximately $80,000–$100,000/year in franchise tax. Under the APVC Method, the calculation is based on the ratio of issued shares to gross assets — early-stage companies with high authorized shares but low issued shares and low asset values typically owe $175–$2,000/year. Delaware requires you to proactively file using the APVC method if it's lower. Many startup founders receive their first Delaware franchise tax bill ($80,000+) and panic — a CPA can fix this with an APVC calculation that often reduces the bill to under $500.
Yes, and this is a common structure for entrepreneurs. The operating company (the business with employees, customers, and investors) is a Delaware C-corporation because that's what investors and attorneys expect. The founder holds their equity in the Delaware C-corp through a South Dakota LLC or trust, which provides asset protection and potentially reduces estate tax exposure on the equity value. The South Dakota entity doesn't alter the Delaware C-corp's tax obligations, but it structures the founder's personal ownership for asset protection and estate planning purposes. This two-tier structure is used by sophisticated founders with estate planning attorneys.
Yes. South Dakota is increasingly used for: (1) Cryptocurrency and digital asset holding — no state income tax on gains, strong privacy laws; (2) Real estate holding LLCs — low annual costs, strong charging order protection, privacy for owner names; (3) Family limited partnerships and LLCs for multi-generational wealth planning; (4) Captive insurance companies — SD has a well-developed captive insurance regulatory framework; (5) Retail banking and financial services — many major credit card companies are chartered in South Dakota due to no usury cap on interest rates. Citibank and Discover were both chartered in SD for this reason.
