Families who establish irrevocable trusts tend to spend considerable time on what the trust holds, who benefits, and who serves as trustee. A fourth question receives less attention and can carry comparable weight over a multi-generational horizon: where the trust is administered. That location, known as trust situs, may influence how much state income tax the trust pays, how long the trust can exist, how duties are divided among fiduciaries, how much information becomes public, and how the trust’s assets are treated if a beneficiary faces a creditor claim or a divorce.
This article explains what situs means, why it has become a meaningful planning variable, how four frequently compared jurisdictions differ, and what situs does not accomplish. It is educational in nature and does not constitute legal or tax advice. Trust law is state specific and changes frequently, and the right jurisdiction for one family may be inappropriate for another.
What Trust Situs Means
Situs is often used loosely to describe a trust’s “home state,” but the concept breaks into at least three distinct questions that do not have to share the same answer.
Administrative situs
This is the place where the trust is actually administered: where the trustee is located, where records are kept, where decisions are made, and where accounts are maintained. Administrative situs is what many state statutes reference when they define which trusts they govern.
Governing law
The trust instrument typically designates which state’s law governs the validity, construction, and administration of the trust. Under the Uniform Trust Code and the Restatement (Second) of Conflict of Laws, a settlor’s designation of governing law is generally respected as long as the state has a sufficient connection to the trust and the designation does not violate a strong public policy of another state with a dominant interest.
Tax residency
Each state applies its own tests to decide whether a trust is a resident taxpayer. Those tests may turn on the residence of the grantor at the time the trust became irrevocable, the residence of the trustee, the location of administration, the residence of beneficiaries, or some combination. A trust can be administered in one state, governed by the law of a second, and taxed as a resident of a third. Coordinating all three is the substance of situs planning.
Why Situs Has Become a Planning Variable
For much of the twentieth century, a family’s trust was administered in the family’s home state, often by a local bank, under that state’s law. Three developments changed that default.
- Competition among states. Beginning with Delaware and South Dakota in the 1980s and 1990s, a group of states deliberately modernized their trust codes to attract fiduciary business. Others, including Nevada, Alaska, Tennessee, New Hampshire, and Wyoming, followed. The result is a set of jurisdictions with materially different rules on taxation, duration, fiduciary structure, privacy, and creditor protection.
- The rise of the independent trust company. Families are no longer limited to the trust departments of large banks. Independent trust companies chartered in favorable states can serve as administrative trustee for families located anywhere, which makes selecting a situs a practical option rather than a theoretical one.
- Larger and longer-lived trusts. Federal transfer tax exemptions have expanded substantially over two decades, and the 2025 tax legislation made the enlarged exemption permanent and indexed to inflation. Trusts are now funded with larger amounts and designed to last for generations, so small annual differences in state tax or administrative friction compound into large sums.
How States Tax Trust Income
State income taxation is often the first reason families examine situs, and it is also the area where assumptions tend to be least reliable. The federal government taxes a non-grantor trust on its undistributed income; states then layer their own rules over that framework, and those rules vary widely.
Some states tax a trust primarily because the grantor was a resident when the trust became irrevocable, regardless of where the trustee or beneficiaries now live. Others tax based on the location of the trustee or of administration. Still others look to where beneficiaries reside. California, for example, apportions taxation based on the residence of fiduciaries and non-contingent beneficiaries, and it applies a throwback rule that can tax accumulated income when it is later distributed to a California resident. New York treats a trust created by a New York resident as a resident trust but exempts it if, in a given year, there is no New York trustee, no New York real or tangible property, and no New York source income.
The United States Supreme Court narrowed the outer boundary in North Carolina Department of Revenue v. Kimberley Rice Kaestner 1992 Family Trust (2019), holding that a state may not tax undistributed trust income solely because a contingent beneficiary lives there. The decision was fact specific, and it did not invalidate the other connecting factors states use. In practice, this means a family cannot assume that moving a trustee to a no-tax state eliminates state tax exposure. The trust’s history, the grantor’s residence at creation, and the beneficiaries’ current residences all remain relevant.
Editorial note: Grantor trusts are a separate case. Income of a grantor trust is reported by the grantor, and the grantor’s home state taxes it regardless of where the trust is administered. Situs planning for state income tax is primarily relevant to non-grantor trusts and to grantor trusts that may later become non-grantor trusts, such as after the grantor’s death.
Four Jurisdictions Families Often Compare
The jurisdictions below are among those families and their counsel evaluate with some frequency. The summary reflects general features of each state’s statutes as commonly described by practitioners. Statutes are amended regularly, and families should confirm current law with counsel before relying on any feature.
| Feature | South Dakota | Nevada | Delaware | Tennessee |
|---|---|---|---|---|
| State income tax on trust income | None | None | None for income accumulated for non-resident beneficiaries | None (Hall tax on interest and dividends repealed effective 2021) |
| Rule against perpetuities | Abolished; trusts may be perpetual | 365-year limit | Abolished for personal property; 110 years for real property | 360-year limit |
| Directed trust statute | Yes, with defined roles for investment and distribution advisers | Yes | Yes; among the earliest and more heavily litigated statutes | Yes, modeled on the Uniform Directed Trust Act |
| Self-settled asset protection trust | Yes; two-year limitations period for pre-existing creditors | Yes; two-year period and no statutory exception creditors | Yes; four-year period with exception creditors | Yes (Tennessee Investment Services Trust); two-year period |
| Privacy | Court proceedings may be sealed in perpetuity; quiet trust provisions | Quiet trust provisions available | Quiet trust provisions; Court of Chancery records generally public | Quiet trust provisions; silent trust permitted for a period |
| Decanting statute | Yes | Yes | Yes | Yes |
| Specialized court | No dedicated court; limited case law | No dedicated court | Court of Chancery with deep trust jurisprudence | No dedicated court; growing body of practice |
South Dakota
South Dakota is frequently cited for the breadth of its statutory package: no state income tax, no rule against perpetuities, a well-developed directed trust framework, a self-settled trust statute, and privacy protections that permit court records to be sealed. It also maintains a legislative task force that reviews and updates the trust code annually, which practitioners often view as a signal of durability. The trade-off is a relatively small body of case law, which means some interpretive questions have not been tested in court.
Nevada
Nevada is a popular choice for asset protection.. Its self-settled spendthrift trust statute has a two-year limitations period and does not carve out exception creditors such as divorcing spouses or child support claimants, a feature that distinguishes it from many other states. Nevada also has no state income tax and a 365-year perpetuities period. Families sometimes note that Nevada has fewer large institutional trust companies than Delaware or South Dakota, which can affect trustee selection.
Delaware
Delaware’s principal advantage is institutional depth. Its Court of Chancery has adjudicated trust matters for well over a century, which gives families and fiduciaries a degree of predictability that newer jurisdictions cannot yet replicate. Delaware pioneered the directed trust and continues to refine it. Its income tax exemption applies to income accumulated for beneficiaries who are not Delaware residents, which covers the large majority of families using Delaware trusts. Its self-settled trust statute has a longer four-year seasoning period and recognizes certain exception creditors, which makes it somewhat less protective than Nevada or South Dakota for that specific purpose.
Tennessee
Tennessee has shown significant growth and potential in the past decade.. The repeal of the Hall income tax removed the state’s tax on trust interest and dividends. The perpetuities period was extended to 360 years, the state adopted a modern directed trust act, and the Tennessee Investment Services Trust provides a self-settled asset protection vehicle with a two-year limitations period. Tennessee also permits community property trusts, which can allow married couples from common-law states to obtain a full basis step-up on both halves of trust property at the first death. For families with a connection to Nashville or the broader Southeast, Tennessee may offer these features alongside proximity to the family’s advisers and a trustee they can meet in person.
Alaska, New Hampshire, and Wyoming each offer comparable statutory features and merit consideration depending on a family’s circumstances and existing relationships.
Directed Trusts and the Separation of Duties
One reason favorable-situs states attract long-lived trusts is the directed trust. In a traditional trust, a single trustee holds investment, distribution, and administrative responsibility and bears fiduciary liability for all three. A directed trust statute allows the settlor to divide those functions: an investment adviser or committee directs investments, a distribution adviser directs distributions, a trust protector holds specified powers such as the ability to remove trustees or amend administrative provisions, and an administrative trustee handles custody, accounting, and compliance.
This structure can allow a family to retain its existing investment adviser, keep family members involved in distribution decisions, and still obtain the jurisdictional benefits of a favorable situs through a locally chartered administrative trustee. It also tends to reduce trustee fees, because the administrative trustee is not pricing investment management or discretionary liability into its compensation. The quality of the directed trust statute matters: states differ on how fully the directed trustee is relieved of liability for following directions, and the difference can be significant if a dispute arises.
Asset Protection Considerations
Third-party trusts, meaning trusts created by one person for the benefit of others, generally receive spendthrift protection in every state, and a favorable situs can strengthen that protection through discretionary distribution standards and statutory clarity. Self-settled asset protection trusts, in which the settlor is also a discretionary beneficiary, are a different matter. Roughly twenty states now permit them, and the four jurisdictions above are among the more frequently used.
Families should understand the limits. State asset protection statutes do not override federal law. Section 548(e) of the Bankruptcy Code permits a trustee in bankruptcy to reach transfers to self-settled trusts made within ten years if the transfer was made with actual intent to hinder, delay, or defraud creditors. Fraudulent transfer law applies in every state. Courts in the settlor’s home state have, in several published decisions, declined to apply the protective law of the trust’s situs when the settlor, the assets, and the creditor all had stronger connections to the home state. Asset protection planning tends to work when it is done early, with assets the family can afford to place outside its own reach, and for reasons that can be documented as legitimate estate planning rather than creditor avoidance.
Moving an Existing Trust: Change of Situs and Decanting
Many families hold trusts that were created decades ago under the law of a state that has since become less favorable, or that were not evaluated on this dimension at the time. Relocating an existing trust is often possible, though the process depends on the trust instrument and the law of both the current and the proposed jurisdiction.
- Instrument-based change. Many modern instruments include a provision allowing the trustee or a trust protector to change situs and governing law without court involvement. If such a provision exists, the transfer may be accomplished by appointing a trustee in the new state and formally transferring administration.
- Court petition. Where the instrument is silent, a petition to the court with jurisdiction over the trust may be required. Courts generally approve a change of situs when it serves the interests of the beneficiaries and does not defeat a material purpose of the settlor.
- Decanting. Where the goal is to modernize the trust’s terms as well as its location, the trustee may be able to “decant” by distributing the assets into a new trust with updated provisions under the new state’s decanting statute. Decanting can raise tax questions, including whether it constitutes a taxable gift by any beneficiary or affects grandfathered generation-skipping transfer status, and it requires careful analysis.
A change of situs does not by itself change the trust’s state tax residency. If the original state taxes trusts based on the grantor’s residence at creation, the trust may remain a resident of that state even after administration moves. Counsel typically analyzes the departure state’s rules before a move so the family has realistic expectations about the tax result.
What Situs Does Not Solve
A clear-eyed view of situs planning includes its limits.
- Federal transfer taxes. Situs has no effect on federal estate, gift, or generation-skipping transfer tax. Those depend on the structure of the transfer and the applicable exemption, not on the trust’s location.
- Beneficiary-level tax. When a trust distributes income to a beneficiary, that income is generally taxed in the beneficiary’s state of residence. A no-tax situs defers state tax on accumulated income; it does not eliminate tax on income the beneficiary eventually receives, and throwback rules in some states can reach accumulated income at distribution.
- Source income. Income from real property or a business operating in a particular state is generally taxable in that state regardless of where the trust is administered.
- Family dynamics. A favorable statute does not resolve disagreements among beneficiaries, and a distant administrative trustee can feel less accessible to family members who valued a local relationship. Governance design and communication matter as much as jurisdiction.
A Framework for Evaluating Situs
Families working through this question with their advisers often find it useful to sequence the analysis.
- Identify the objective. Is the priority state income tax deferral, perpetual duration, creditor protection, fiduciary structure, privacy, or a combination? Different priorities point toward different states.
- Map the connecting factors. Where does the grantor live, where did the grantor live when the trust became irrevocable, where do current and likely future beneficiaries live, and where are the assets? These facts determine which state tax rules apply.
- Evaluate the trustee market. A jurisdiction is of limited use without a capable administrative trustee the family is comfortable working with. Fee structure, service model, and institutional stability all matter.
- Assess legal depth versus statutory breadth. Delaware offers precedent; South Dakota and Nevada offer broader statutory features with less case law. Families sometimes weigh these differently depending on how much they value predictability over flexibility.
- Plan the transition. For an existing trust, confirm the mechanism for moving, analyze the departure state’s tax rules, and evaluate whether decanting or a simple change of administration is appropriate.
- Revisit periodically. State law changes. A situs decision made a decade ago may deserve a fresh look, particularly when a grantor relocates, a beneficiary moves, or a trust becomes non-grantor.
Certuity’s family office and tax strategy teams work alongside a family’s estate counsel to evaluate these questions in the context of the family’s complete balance sheet, including how trust situs interacts with residency planning, business ownership, and charitable structures. The goal is not to find a single “right” state but to align the trust’s home with the purposes the family has for it.
Key Takeaways
- Trust situs involves three separate questions: where the trust is administered, which state’s law governs, and which state treats the trust as a resident taxpayer.
- State income tax rules for trusts vary by state and may depend on the grantor’s residence at creation, the trustee’s location, or beneficiary residence. Kaestner limited but did not eliminate these connecting factors.
- South Dakota, Nevada, Delaware, and Tennessee each offer no state income tax on accumulated trust income for non-resident families, extended or perpetual duration, directed trust statutes, and self-settled asset protection trusts, with meaningful differences in privacy, case law depth, and creditor exceptions.
- Directed trusts allow families to keep their existing investment adviser and retain a role in distribution decisions while using an administrative trustee in a favorable jurisdiction.
- Existing trusts can often be moved through instrument provisions, court petition, or decanting, but a move does not automatically change state tax residency.
- Situs does not affect federal transfer taxes, beneficiary-level state tax on distributions, or tax on state-source income.
Frequently Asked Questions
What is trust situs?
Trust situs refers to the jurisdiction in which a trust is administered and whose law governs it. It is distinct from, though related to, the state that treats the trust as a resident for income tax purposes. The three concepts can point to different states, and coordinating them is a central part of trust planning.
Which states are considered favorable for trust situs?
South Dakota, Nevada, Delaware, Tennessee, Alaska, New Hampshire, and Wyoming are among the jurisdictions frequently cited for modern trust statutes. They generally share the absence of state income tax on accumulated trust income for non-resident families, extended or perpetual trust duration, directed trust provisions, and self-settled asset protection trust statutes, though the details differ.
Can I move an existing trust to a different state?
Often, yes. Many trust instruments permit a trustee or trust protector to change situs. Where the instrument is silent, a court petition may be needed. Decanting into a new trust under the new state’s statute is another route. Each approach has tax and fiduciary considerations, and the departure state’s tax rules may continue to apply depending on how that state defines a resident trust.
Does moving a trust to a no-tax state eliminate state income tax?
Not necessarily. Some states tax trusts based on the grantor’s residence when the trust became irrevocable, and income distributed to beneficiaries is generally taxed in the beneficiary’s home state. A favorable situs may defer state tax on accumulated income but does not remove every layer of state taxation.
What is a directed trust?
A directed trust divides fiduciary responsibilities among multiple parties: an administrative trustee, an investment adviser or committee, a distribution adviser, and often a trust protector. State directed trust statutes define the extent to which the administrative trustee is relieved of liability for following the directions of the other parties.
How does trust situs interact with residency planning?
Closely. A family relocating from a high-tax state to a no-tax state may consider whether existing trusts should move as well, and whether new trusts should be established in the new state or in a specialized trust jurisdiction. The grantor’s residence at the time a trust becomes irrevocable is a connecting factor in many states, which is one reason timing can matter.
