Why South Dakota Is the Most Popular Trust Jurisdiction in the United States

Plain and simple, South Dakota is the most popular trust jurisdiction in the United States. It has surpassed Nevada, Delaware, Wyoming, Alaska, and every other state in both popularity and reputation. Families from across the country—and even from around the world—look to South Dakota for their trust planning. Here’s why.

South Dakota Leads in Trust Companies

One of the most overlooked facts is that South Dakota has more registered trust companies than any other state. This alone shows the sheer volume of trust administration taking place within its borders.

While trust companies in other states often come and go, South Dakota has built a long-standing, stable environment where institutions continue to thrive decade after decade. The demand is so significant that new trust companies continue to open just to keep up with client needs.

Flexibility: A Hallmark of South Dakota Law

South Dakota is the most popular jurisdiction because it has the most flexible trust laws.

Decanting Laws

One standout feature is decanting—the ability to move assets from one irrevocable trust into another. This ensures families are not locked into outdated or ineffective trust structures. South Dakota’s statutes are the most liberal in the nation, making it easier to adapt trusts as circumstances change.

Directed Trusts

South Dakota also has the strongest directed trust laws. Unlike in many states, where one trustee must handle every aspect of management, South Dakota allows responsibilities to be divided among specialists. For example:

• A financial advisor can manage the investments.

• Another advisor can oversee distributions.

• An administrative trustee can handle reporting and compliance.

Each role has clearly defined duties and liabilities. This “part and parcel” model allows families to handpick the best professionals for each task while maintaining maximum control.

Privacy and No State Income Tax

South Dakota also sets itself apart with unmatched privacy protections. Trust records remain confidential, shielding family information from the public.

In addition, South Dakota imposes no state income tax, making it especially attractive for high-net-worth individuals seeking to maximize wealth preservation. While other favorable states may also avoid state income tax, South Dakota couples that advantage with superior flexibility and protections.

Best-in-Class Asset Protection

South Dakota’s asset protection laws are widely considered the strongest in the country.

Particularly noteworthy are its favorable rules surrounding fraudulent conveyance doctrine and statutes of limitation. Compared to states like Nevada and Wyoming, South Dakota offers shorter limitation periods and stronger protection for debtors and beneficiaries. This creates formidable barriers against creditors.

Progressive Trust Law Reform

Another reason South Dakota remains number one is its ongoing commitment to modernization.

The Governor’s Task Force on Trust Administration and Reform meets regularly to review case law, tax developments, and competitive legislation from other states. The task force ensures South Dakota laws stay ahead of the curve.

For example, new legislation effective July 1 introduced a tax advisor role within directed trusts—further refining flexibility for families and advisors.

Dynasty Trusts That Last Forever

Finally, South Dakota was the first state to abolish the rule against perpetuities in the 1980s, creating the first true dynasty trust in the nation. Unlike states where trusts must terminate after a set period (such as 100 or even 1,000 years), a South Dakota dynasty trust can last forever.

When structured properly, these trusts avoid estate taxes, generation-skipping transfer taxes, and other wealth transfer taxes indefinitely. This makes them the ultimate vehicle for multigenerational planning.

Conclusion: Why South Dakota Stands Alone

South Dakota’s combination of flexibility, privacy, tax advantages, asset protection, and forward-looking lawmaking makes it the most popular trust jurisdiction in the United States. With more trust companies than any other state and a proven record of innovation, it continues to attract families from across the globe.

For those seeking the strongest and most adaptable framework for protecting and growing wealth, South Dakota remains unmatched.
