Why So Many Trusts Are Written in Nevada and South Dakota — Not Wherever You Actually Live

Our Trusts 101 piece covered the basic revocable-versus-irrevocable decision. It sidestepped a question that comes up almost immediately once someone starts researching irrevocable and asset-protection trusts: why do so many of them get written under the laws of Nevada, South Dakota, or Wyoming, for people who have never set foot in any of the three? The answer is that a trust's "situs" — its legal home state — is a choice, not a fact tied to your own address. What differs by state is real, and it's worth understanding before assuming your home state's default trust law is the only option.

The four things that actually differ, state to state

• State income tax on trust income. Some states tax income earned inside a trust; several impose none, regardless of where the beneficiaries live.
• Asset-protection statute of limitations. States that allow self-settled asset-protection trusts (where you can be a beneficiary of your own protected trust) set different waiting periods before the assets are shielded from a creditor's claim.
• Dynasty trust duration. Every state has, or has abolished, some version of the rule against perpetuities — the old common-law limit on how long a trust can legally exist before it must terminate.
• Privacy and flexibility. How easily an outdated trust can be modified (decanting), whether court records are sealed, and whether the state allows a family to run its own unregulated private trust company.

Nevada: the asset-protection leader

Nevada charges no state income tax on trust income, and its trusts can run for 365 years — not literally forever, but close enough for any realistic planning horizon. Its standout feature is a creditor statute of limitations of roughly two years from when assets are transferred into the trust, among the shortest in the country. Once that window closes, a properly funded Nevada asset-protection trust is very difficult for a future creditor to reach.

South Dakota: the privacy-and-tax combination

South Dakota is frequently cited as the closest thing to a "gold standard" alongside Nevada: zero state income tax, trusts that can run in perpetuity, and a distinctive feature few other states offer — court records related to trust matters are automatically and permanently sealed. For families whose main concern is keeping the size and structure of their estate out of public view, that combination is hard to match.

Wyoming: privacy and low cost

Wyoming pairs no state income tax with genuinely low administrative costs and a distinctive legal tool: it allows families to form their own unregulated private trust company, giving multiple family members a formal, ongoing role in trust governance rather than handing everything to a single outside corporate trustee.

Delaware: the business-holdings specialist

Delaware's advantage isn't tax or asset protection — its self-settled trust protection is generally considered somewhat less robust than Nevada's or South Dakota's. What Delaware offers instead is its Court of Chancery, a specialized business court with more than two centuries of case law and judges experienced specifically in complex trust and corporate disputes. For a trust holding a closely held business, private equity interests, or other legally complicated assets, that expertise is often the deciding factor.

Alaska: the pioneer, still relevant

Alaska was the first state to authorize domestic asset-protection trusts back in the 1990s, and it still offers no state income tax alongside strong flexibility. It remains a legitimate option, even though Nevada and South Dakota have since become the more commonly cited default recommendations among estate attorneys.

What about Montana?

Montana does have a real asset-protection trust statute — its Qualified Dispositions in Trust Act allows self-settled trusts that can shield assets from future creditors. It also taxes irrevocable trust income only when distributed to Montana-resident beneficiaries, and a revocable living trust there is a private document that isn't filed with any court. But Montana has not abolished the rule against perpetuities the way Nevada, South Dakota, and Wyoming have; trusts there still generally must terminate within the traditional common-law window of roughly 90 years or "lives in being plus 21 years." That's a meaningfully shorter horizon than a true dynasty trust, which is the main reason Montana doesn't appear alongside the other four in most trust-jurisdiction rankings, despite having genuine, real advantages of its own.

The part that actually matters: this isn't a DIY move

None of this works by simply typing a different state's name into a trust document. To legitimately benefit from another state's trust law, the trust generally needs a real connection to that state — commonly an in-state corporate trustee actually administering the trust, not just a mailing address. That means real, ongoing trustee fees, and it means the choice has to be made correctly from the start with an estate attorney experienced in the specific jurisdiction, not assembled from a template. It is also, for most families, entirely beside the point: a standard revocable living trust used to avoid probate is taxed to you personally regardless of which state it's nominally sited in, so nothing here changes anything for the version of a trust most middle-class households actually need.

Who this is actually worth it for

• Large irrevocable trusts or dynasty trusts where decades of tax-free growth and multi-generational duration are the whole point — the added trustee cost is small relative to what's being protected.
• High-liability professions — physicians, business owners, anyone with meaningful lawsuit exposure — where a self-settled asset-protection trust's creditor statute of limitations is the actual feature being purchased.
• Families who prioritize privacy over the modest added cost, for whom South Dakota's sealed-record approach specifically addresses a concern that no amount of asset value alone would.

For everyone else — the much larger group whose main goals are avoiding probate, naming guardians, and having a plan for incapacity — a properly funded trust in your own home state, drafted by a competent local estate attorney, remains the right and simpler answer. Out-of-state situs is a specialized tool for a specific, real problem. It isn't an upgrade every trust needs.
