Detailed Comparison

Dynasty Duration

Alaska

95
1,000 years

Alaska allows trusts to exist for up to 1,000 years, measured from the date of trust creation. This applies to both real and personal property held in trust. While not perpetual, 1,000 years is effectively dynastic for any planning purpose.

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

Alaska

100
No state income tax

Alaska has no state income tax. The state relies on oil revenues and other sources rather than income tax. Trust income is not taxed at the state level, and Alaska residents receive annual Permanent Fund Dividends.

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

Alaska

88
First US DAPT state (1997) with 4-year statute of limitations

Alaska enacted the first US Domestic Asset Protection Trust statute in 1997. The statute of limitations for fraudulent transfer claims is 4 years from transfer or 1 year from discovery, whichever is later. This is longer than some competing jurisdictions.

  • ⚠️ 4-year statute of limitations is longer than South Dakota or Nevada (2 years)
  • ⚠️ Child support is always an exception creditor
  • ⚠️ Spousal support claims may reach assets
  • ⚠️ Tort claims arising before transfer may reach assets

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

Alaska

92
Comprehensive directed trust and trust protector statutes

Alaska has comprehensive directed trust and trust protector statutes. The statutes allow separation of trustee powers among multiple parties with explicit liability protection. Trust protectors can be granted broad powers including modification of trust terms, removal of trustees, and change of situs.

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

Alaska

90
Broad decanting powers with notice requirement

Alaska's decanting statute (enacted 2014) allows trustees with discretionary distribution authority to distribute to new trusts with modified terms. No court approval is required. Decanting can modify administrative and dispositive provisions, merge or divide trusts, and extend trust terms.

  • ⚠️ Cannot reduce fixed income interests
  • ⚠️ Cannot eliminate vested interests
  • ⚠️ Must give 60 days notice to qualified beneficiaries

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: AK vs SD

South Dakota is the better choice for most people. Alaska pioneered many trust innovations, but SD has surpassed it with better infrastructure and more trust companies.

Choose Alaska If...

You have Alaska connections, assets already there, or value being the 'original' DAPT jurisdiction.

Choose South Dakota If...

You want the most established trust industry, easier administration, and more trustee options.

Real Talk

Alaska was groundbreaking in 1997. Today, it's like choosing a flip phone because it was revolutionary in 2005. SD has caught up and passed it.
