Detailed Comparison

Dynasty Duration

Delaware

100
Perpetual

Delaware abolished the Rule Against Perpetuities for interests in trust property effective July 1, 1995. Trusts can continue indefinitely with no durational limit, making Delaware one of the premier dynasty trust jurisdictions.

South Dakota

100
Perpetual

South Dakota abolished the Rule Against Perpetuities in 1983, allowing trusts to last indefinitely. South Dakota was one of the first states to abolish the RAP and remains a leader in dynasty trust planning.

State Income Tax

Delaware

85
No tax with conditions

Delaware does not tax trust income if: (1) all current beneficiaries are non-Delaware residents, (2) there is no Delaware-source income, and (3) trustee location alone does not create tax nexus. Delaware statutory trustees/directed trustees do not create income tax liability by themselves.

  • ⚠️ Distributions to Delaware resident beneficiaries may be taxable
  • ⚠️ Delaware grantor trusts with Delaware resident grantor may be taxable
  • ⚠️ If taxable, Delaware's top marginal rate is 6.6%

South Dakota

100
No state income tax

South Dakota's constitution prohibits a state income tax. This applies to all income including trust income, making it one of the most favorable states for accumulating wealth within a trust.

Asset Protection

Delaware

88
Strong DAPT with 4-year statute of limitations

Delaware's DAPT statute requires creditors to prove fraudulent transfer by 'clear and convincing evidence' - a higher standard than typical civil cases. The 4-year statute of limitations (or 1 year from discovery, whichever is later) provides strong protection after seasoning.

  • ⚠️ Child support and alimony are exception creditors
  • ⚠️ Pre-existing tort claims may reach assets
  • ⚠️ 4-year SOL is longer than South Dakota or Nevada (2 years)
  • ⚠️ Federal/state tax obligations remain exception claims

South Dakota

95
Strong DAPT with 2-year statute of limitations

South Dakota enacted its Domestic Asset Protection Trust legislation in 1997. The statute features a 2-year statute of limitations for fraudulent transfer claims, one of the shortest in the nation. Self-settled spendthrift trusts are permitted.

  • ⚠️ Child support and alimony obligations are exception creditors
  • ⚠️ Existing creditors at time of transfer may still have claims if transfer was fraudulent

Directed Trust & Trust Protector

Delaware

100
Most comprehensive directed trust statutes in the US

Delaware is widely recognized as having the most sophisticated directed trust statute in the nation. The statute allows complete separation of administrative, investment, and distribution functions with explicit liability protection. Trust protectors can be granted broad powers and are not fiduciaries unless the trust instrument provides otherwise.

South Dakota

100
Comprehensive directed trust and trust protector statutes

South Dakota is widely recognized as having the most comprehensive directed trust statutes in the nation. The state allows complete separation of investment and distribution responsibilities with explicit liability protection for directed trustees. Trust protector statutes are equally robust.

Decanting Flexibility

Delaware

95
Broad decanting powers with 60-day notice

Delaware's decanting statute is one of the most permissive in the nation. Trustees with discretionary distribution authority can decant to new trusts with modified terms, extend trust duration (perpetual in Delaware), and change situs. No court approval required.

  • ⚠️ Cannot benefit persons not already beneficiaries without existing power of appointment
  • ⚠️ HEMS standard trusts may only decant to equally or more restrictive standards

South Dakota

95
Broad decanting powers

South Dakota permits broad decanting with minimal court involvement. Trustees with discretionary distribution authority can decant to new trusts with modified terms, including changes to beneficial interests, administrative provisions, and trust protector powers.

The Bottom Line: DE vs SD

This is the real debate. Delaware has unmatched legal sophistication; SD has no state income tax. Your choice depends on complexity vs. simplicity.

Choose Delaware If...

Your trust is complex, you expect legal challenges, or you're working with Delaware specialists.

Choose South Dakota If...

You want to avoid state income tax complexity and prefer the most straightforward option.

Real Talk

Delaware is for the 5% of trusts that are genuinely complex. For a standard dynasty trust, it's overkill. The income tax trap catches more people than you'd think.
