South Dakota Trust Advantages
South Dakota is the leading US jurisdiction for trust planning — over $500 billion in trust assets are administered under South Dakota law.
South Dakota has abolished the rule against perpetuities — trusts can last indefinitely (forever). Wealth can be held in trust for multiple generations without estate tax at each generation, compounding tax-free.
Domestic Asset Protection Trusts allow you to be a discretionary beneficiary of your own trust while protecting assets from future creditors. 2-year statute of limitations for creditor claims.
Domestic Incomplete Non-Grantor (DING) trusts can shift investment income to South Dakota, eliminating state income tax on trust earnings for residents of high-tax states — subject to IRS scrutiny.
SD allows "directed trusts" separating investment direction from trustee responsibilities, allowing families to use their own investment advisors while the trustee handles administrative duties.
Bank Franchise Tax — Why Major Banks Chose South Dakota
In 1980, Citibank relocated its credit card operations to South Dakota after the state eliminated usury caps (interest rate limits) and offered favorable banking regulation. Today, many of the largest US banks operate credit card divisions from South Dakota:
- No state income tax on bank profits
- No usury limit — banks can charge any interest rate
- Favorable trust and fiduciary laws
- Strong privacy — strict confidentiality for trust and banking records
The bank franchise tax (0.25% of net income) is minimal compared to corporate income taxes in other states.
