Top U.S. States for Trusts: Tax Benefits and Flexibility

Pick your jurisdiction based on the specific job required instead of marketing rankings—and be aware that most of those rankings are published by trust companies chartered in the state that wins. The six states below all eliminate state income tax on accumulated trust income and all extend or abolish the Rule Against Perpetuities, so those headline features tell you nothing about which to choose. What separates them is one specialty each ( Table 23.13).

Before you shop, price the full exercise realistically. Claiming any of this requires genuine nexus: a resident trustee, normally a corporate trust company chartered in that state, with administration actually conducted there—which means you are hiring an institutional trustee and paying institutional fees (section “Choosing a Corporate Trustee: Pros and Cons”) for as long as the trust runs. A mail-drop and a form does not survive scrutiny. If your trust is small enough that the fee swamps the benefit, stay home. And read the next subsection before you celebrate the tax saving, because your own state may tax the trust regardless of where it sits.

Two caveats apply to that comparison: the creditor look-back periods quoted are the two that are precisely fixed by statute and widely litigated; the remaining DAPT states cluster around four years, but the periods and the standard of proof vary and are amended often, so confirm the current statute before relying on a number. And none of it displaces the federal ten-year clawback in bankruptcy under 11 U.S.C. §548(e) (section “Domestic Asset Protection Trusts (DAPTs)”).

The Catch: Your Home State May Tax the Trust Anyway

Before you celebrate the South Dakota income-tax savings, understand who actually gets taxed. A state does not tax a trust because it sits in a vault in Sioux Falls; it taxes based on connections to the state—and the connections that matter are the residence of the grantor, the trustee, the administration, and above all the beneficiaries. California is the aggressive case every reader here should assume applies to them. Under R&TC §§17742–17745, California taxes a trust’s undistributed income if either a trustee or a non-contingent beneficiary is a California resident. Park your dynasty trust in Nevada with a Nevada trustee, but if your children who can receive distributions live in Los Angeles, California taxes the trust’s income on a pro rata basis—and its throwback rule can reach back and tax income that was accumulated tax-free in prior years once it is finally distributed to a California beneficiary.

The Supreme Court drew a constitutional floor in North Carolina Dept. of Revenue v. Kaestner (2019): a state may not tax a trust based solely on the in-state residence of a beneficiary who has no right to demand distributions and has received nothing. But Kaestner is narrow—it does not help when a beneficiary is currently receiving distributions or the trustee is in-state, and it says nothing about California’s trustee-based hook. The practical playbook: use an out-of-state corporate trustee with no California co-trustee, keep administration outside California, and recognize that real escape from California trust tax usually requires the beneficiaries to also live outside California—or for the trust to accumulate (and pay the lower out-of-state cost) until they do. A situs state buys you no income-tax relief on distributions to a resident child; it shelters accumulated income, which is exactly why the compressed federal trust brackets (section “Trust Accounting and Fiduciary Taxation”) and state residency must be modeled together.

The NING and Why It No Longer Works in California

Sooner or later someone will pitch you a Incomplete Gift Non-grantor Trust (ING)—branded by situs as a NING (Nevada), DING (Delaware), or WING (Wyoming). If you are a California resident, the answer is no. The structure is dead here, and the promoter selling it is either behind on the law or counting on you being behind on it.

Understand what it was, because the logic is genuinely clever. You want to sell a concentrated position or a company and avoid California’s 13.3% top rate on the gain. You cannot simply give the asset away—that costs lifetime exemption and gift tax. So you thread the needle: transfer the asset to a trust in a no-income-tax state, drafted so that the gift is incomplete for gift tax purposes (you keep enough control, via a distribution committee and a retained power of appointment, that nothing has been given away), while the trust is a non-grantor trust for income tax purposes (so its income is not taxed back to you). The trust is therefore its own taxpayer, resident in Nevada, paying no state tax—and it sells the asset. No gift tax, no California tax. That was the trade for roughly a decade.

California closed it with Senate Bill 131 (2023), signed July 2023 and made retroactive to tax years beginning on or after January 1, 2023. New Revenue and Taxation Code §17082 provides that the income of an incomplete gift non-grantor trust is included in the California grantor’s gross income as though the trust were a grantor trust. The entire mechanism—non-grantor status for income tax while the gift stays incomplete—is simply disregarded for California purposes. New York did the same thing in 2014. If you are a California resident and you fund a NING today, you have paid for Nevada trustee fees, a distribution committee, and an annual Form 1041, and you owe exactly the California tax you were trying to avoid.

What actually works, in descending order of reliability. Move. Establish residency outside California well before the liquidity event, and understand that the Franchise Tax Board audits part-year departures aggressively—the date of sale relative to your change of domicile is the whole case. Give it away for real. A completed gift to an irrevocable non-grantor trust in a no-tax state does work, because the incompleteness is what §17082 attacks; the price is that you have genuinely parted with the asset and spent lifetime exemption, representing a real economic cost, not a loophole. A SLAT (section “Spousal Lifetime Access Trusts (SLATs)”) or a sale to an IDGT (section “Intentionally Defective Grantor Trusts (IDGTs)”) gets you there while keeping the wealth in the family. Or accept the tax, harvest offsetting losses, and stop paying promoters for structures the legislature already killed. There is a general lesson here worth more than the specific statute: a strategy that depends entirely on a state not noticing has a shelf life, and you are the one holding it when the statute changes retroactively.

Trust Decanting

“Irrevocable” turns out to be negotiable. If you are a beneficiary or trustee of a trust drafted decades ago under law that no longer exists, for a family that no longer looks like that, decanting is how you fix it without a courtroom. The trustee “pours” the assets from the old trust into a new one with better terms, on the theory that a trustee who may distribute principal outright to a beneficiary may instead distribute it to a trust for that beneficiary. Most states now authorize it by statute—Nevada NRS §163.556, Delaware 12 Del. C. §3528, South Dakota SDCL §55-2-15, and in California the Uniform Trust Decanting Act at Probate Code §§19501 et seq., effective 2019.

Use it to modernize administrative provisions—swapping trustees, adding a trust protector, changing situs to a no-income-tax state; to split one pot trust into separate shares when siblings stop cooperating; to add spendthrift or asset-protection language for a beneficiary facing a divorce or a judgment; or to repair drafting that tax law has overtaken, such as a mandatory income-distribution clause that now forces income out at the wrong time given the compressed trust brackets.

Know the limits before you get attached to the idea. The trustee needs discretionary authority over principal in the first place—a purely ministerial trustee has nothing to exercise. You generally cannot add beneficiaries who were not already in the class, cannot defeat a material purpose of the original trust, and cannot use decanting to strip a vested interest from someone who already has one. Beneficiaries must be notified (in California, Prob. Code §19507), and while their consent is not required, their objection buys litigation. Most importantly, treat the tax consequences as a separate analysis, not an afterthought: a decanting can jeopardize a trust’s grandfathered GST inclusion ratio, and Chief Counsel Advice 202352018 concluded that a beneficiary-approved modification adding a grantor tax-reimbursement clause is a taxable gift by those beneficiaries (section “Intentionally Defective Grantor Trusts (IDGTs)”). Get the tax opinion before the trustee signs, not afterward.
