Estate Planning · Irrevocable Trusts
You give up control. You should get something specific back.
Every trust below trades ownership for one defined benefit. This is what each one actually buys.
An irrevocable trust works precisely because you cannot undo it. Property you can take back is property the IRS still counts in your estate and your creditors can still reach; property you have genuinely surrendered is neither. That surrender is the price, and it is a real one. So the only sensible way to approach this category is backwards — start with the specific benefit you need, and accept only the amount of control you must give up to get it. Below is every type of irrevocable trust available in Missouri, grouped by what it does.
The trade
What you give up, and what you get for it.
You give up control
You are no longer the owner. You generally cannot serve as sole trustee with unrestricted discretion, cannot take the property back, and cannot change beneficiaries at will — retaining any of those defeats the purpose under IRC §§ 2036 and 2038.
You usually give up the basis step-up
Property outside your estate gets no new basis at death under § 1014 — it carries your original basis instead. Rev. Rul. 2023-2 makes this explicit. For a family that will never owe estate tax, this cost frequently exceeds the benefit.
You take on administration
A separate taxpayer identification number, a fiduciary income tax return, trustee duties, and the beneficiary notice and reporting obligations of RSMo § 456.8-813. Trust income tax brackets also compress sharply — the top rate arrives at a very low level of retained income.
You get estate exclusion
Assets and, more importantly, all their future growth sit outside your taxable estate. This is the point of every structure in the tax-reduction group.
You get creditor protection
Property you no longer own is generally beyond your creditors. Missouri is unusually favorable here, permitting self-settled spendthrift trusts under RSMo § 456.5-505.3 since the 1980s.
You get eligibility and permanence
Assets held for a beneficiary with a disability do not count against public benefits. Assets transferred long enough ago do not count for long-term care. And a Missouri trust can run for generations under § 456.025.
“Irrevocable” is less permanent than the word suggests. Missouri gives trustees and beneficiaries several routes to fix a trust that no longer works. The most powerful is decanting under RSMo § 456.4-419: a trustee with discretionary distribution authority may distribute the trust property into a second trust with better terms, or modify the first trust directly. Written notice to the permissible distributees of both trusts is required at least sixty days beforehand, at least one beneficiary must be common to both, and the second trust may not add beneficiaries who were not in the first. Tax-qualification protections are built in for marital and charitable deductions, GST status and S corporation eligibility, with special rules protecting beneficiaries with disabilities. Missouri enacted this in 2011 and strengthened it in 2022. Beyond decanting there is modification by consent of the settlor and beneficiaries, and judicial modification for circumstances nobody anticipated. An old irrevocable trust that has stopped serving its purpose is very often fixable — which is worth knowing before anyone tells you it is set in stone.
The catalog
Every irrevocable trust available in Missouri, by what it does.
Reducing estate and gift tax
Irrevocable life insurance trust (ILIT)
Owns a policy so the death benefit sits outside your taxable estate under IRC § 2042. Supplies the cash to pay an estate tax that would otherwise force a sale. Transferring an existing policy triggers a three-year lookback under § 2035(a).
Grantor retained annuity trust (GRAT)
You keep a fixed annuity for a term; everything the asset earns above the § 7520 rate passes tax-free to your beneficiaries. A “qualified interest” under § 2702. Best for volatile or sharply appreciating assets.
Grantor retained unitrust (GRUT)
The same idea with a fixed percentage of annually revalued assets rather than a fixed dollar annuity. Rarer than the GRAT, because revaluing each year usually works against the grantor.
Qualified personal residence trust (QPRT)
Transfers a home at a discounted gift value while you keep the right to live in it for a term of years. The residence exception in § 2702(a)(3)(A)(ii). You must outlive the term.
Intentionally defective grantor trust (IDGT)
Outside your estate but inside your income tax return, using a power under § 675(4)(C). Lets you sell an appreciating asset to it with no capital gain, and pay its income tax personally — a further transfer that is not a gift.
Spousal lifetime access trust (SLAT)
You use your exclusion by gifting to a trust for your spouse, who may receive distributions — so the family retains indirect access. Divorce or the death of that spouse closes the door, which is the risk.
Dynasty trust
A trust designed to run for generations, sheltered from transfer tax at each one by an allocation of GST exemption under § 2631. Missouri permits it — RSMo § 456.025 disapplies the rule against perpetuities where the trustee holds a power of sale.
Credit shelter (bypass) trust
Funded at the first spouse’s death with the exclusion amount. Provides for the survivor without being taxed again in the survivor’s estate. Less essential now that portability exists, still valuable for growth and for control.
QTIP and marital trusts
Qualifies for the marital deduction under § 2056(b)(7) while you decide who takes after your spouse. The standard answer for a second marriage.
Qualified domestic trust (QDOT)
Where a surviving spouse is not a U.S. citizen the marital deduction is unavailable unless property passes to a QDOT meeting § 2056A — including a U.S. trustee with authority to withhold the tax.
Crummey trust
Any irrevocable trust giving beneficiaries a temporary withdrawal right so contributions qualify for the annual exclusion, under Crummey v. Commissioner, 397 F.2d 82 (9th Cir. 1968). The mechanism most ILITs run on.
Minor’s trust — § 2503(c)
A gift to a trust for someone under twenty-one qualifies for the annual exclusion if the property may be spent for them before twenty-one and what remains passes to them at twenty-one. IRC § 2503(c).
Charitable giving
Charitable remainder annuity trust (CRAT)
Pays you a fixed sum for life or a term, then the remainder goes to charity. Payout between 5 and 50 percent, with a charitable remainder of at least 10 percent. IRC § 664(d)(1).
Charitable remainder unitrust (CRUT)
The same, but paying a fixed percentage of assets revalued annually — so the payment rises with the portfolio, and additional contributions are allowed. § 664(d)(2). Includes the NIMCRUT and flip variants.
Charitable lead trusts (CLAT and CLUT)
The mirror image: charity is paid first for a term, and your family receives what remains. A grantor CLAT can generate a large immediate income tax deduction under § 170(f)(2)(B).
Pooled income fund
Your gift is commingled with other donors’ in a fund maintained by the charity itself; you receive a share of the fund’s income for life. § 642(c)(5). Lower cost than a private trust for a modest gift.
Private foundations and donor advised funds
Not trusts in the same sense, and frequently the better answer. A donor advised fund gives most of the benefit with almost none of the administration; a private foundation buys control and family involvement at the cost of real compliance.
Protecting assets from creditors
Missouri self-settled spendthrift trust
Missouri’s domestic asset protection trust. Under RSMo § 456.5-505.3, an irrevocable trust with a spendthrift provision can shield assets from the settlor’s own creditors — if it was not a fraudulent transfer and you are not the sole beneficiary or a holder of a retained power to amend.
Third-party spendthrift trust
The everyday version, and by far the most common. A trust you create for your children with a spendthrift provision valid under § 456.5-502, protecting their inheritance from their creditors and their divorce.
Fully discretionary trust
The strongest form of beneficiary protection. If the trustee alone decides whether to distribute and the beneficiary can compel nothing, there is little for a creditor to attach.
Missouri qualified spousal trust
Revocable rather than irrevocable, but it belongs in this list. RSMo § 456.950 preserves tenancy-by-the-entirety creditor immunity for a married couple’s property held in a joint revocable trust. Nearly free, and widely missed.
Inheritance protection trusts
A child’s share held in a lifetime trust rather than paid out. The child can serve as trustee within limits and still enjoy substantial protection from divorce, creditors and their own judgment.
Protecting a beneficiary with a disability
Third-party special needs trust
Funded with your money for a loved one with a disability. No Medicaid payback, no age limit, and whatever remains can pass to your other children. The right answer whenever a parent or grandparent is planning ahead.
First-party (d)(4)(A) trust
Funded with the beneficiary’s own money — a settlement, an inheritance received outright. Must be established before age 65 and must repay the state at death. 42 U.S.C. § 1396p(d)(4)(A).
Pooled (d)(4)(C) trust
A separate account within a trust managed by a non-profit. Practical for smaller amounts, with no federal age limit. § 1396p(d)(4)(C).
Long-term care and Medicaid
Medicaid asset protection trust
An irrevocable income-only trust funded more than five years before an application, so the assets are no longer countable. The look-back is 60 months under 42 U.S.C. § 1396p(c) — timing is the entire game.
Irrevocable funeral trust
A small, exempt, irrevocable trust prepaying funeral and burial costs. Not counted as a resource, and one of the few moves that still works inside the look-back period.
Testamentary trust for a surviving spouse
A trust created in the will of the first spouse to die can hold assets for the survivor without those assets counting for the survivor’s own long-term care eligibility — a result a living trust cannot achieve.
Specific kinds of property
NFA (gun) trust
Holds suppressors, short-barreled rifles and other National Firearms Act items — 26 U.S.C. ch. 53 — so more than one person may lawfully possess them and they transfer at death without a felony. Every responsible person files under ATF Rule 41F.
Retirement plan (see-through) trust
A trust named as beneficiary of an IRA or 401(k), drafted as a conduit or an accumulation trust. The SECURE Act ten-year rule under IRC § 401(a)(9)(H) made getting this right considerably harder.
Pet trust
RSMo § 456.4-408 allows an enforceable trust for the care of an animal alive during your lifetime, with a named enforcer and a court able to return any excess funding.
QSST and ESBT
The two elective vehicles for a trust to hold S corporation stock indefinitely without terminating the election — the qualified subchapter S trust under IRC § 1361(d) and the electing small business trust under § 1361(e).
Testamentary trust
Created inside a will and springing into existence at death. Inexpensive to draft and the assets still pass through probate to reach it — the trade-off worth understanding.
Life insurance beneficiary trust
A simple trust named as policy beneficiary purely to manage the proceeds for young children — no tax purpose at all. Frequently the only trust a young family actually needs.
Choosing
Start with the problem, not the product.

“My estate is over $15 million.” Look at the tax-reduction group — and start with the cheapest moves. Annual exclusion gifting, direct tuition and medical payments, and a portability election cost almost nothing. Structures come after.
“I own something that will be worth far more later.” A GRAT or a sale to an IDGT. These are freeze techniques, and they work best applied while the value is still low.
“My estate is illiquid and the tax would force a sale.” An ILIT, plus a look at § 6166 installment deferral and § 2032A special use valuation. See taxable estate planning.
“I have a child with a disability.” A third-party special needs trust, drafted before anyone leaves that child money outright. This is urgent in a way most planning is not — an outright inheritance can end benefits the week it arrives.
“I am worried about a lawsuit.” A Missouri qualified spousal trust first, because it is nearly free. Then insurance. Then, if the exposure is genuinely large, a self-settled spendthrift trust — established long before any claim exists.
“I am worried about nursing home costs.” A Medicaid asset protection trust, and the whole question is timing — the sixty-month look-back means this works five years early and does very little five months early.
“I want to give to charity.” A charitable remainder trust if you want income now and a deduction now; a lead trust if you want to pass assets to family at a reduced transfer tax cost. Frequently a donor advised fund does the job for far less.
“I own suppressors or short-barreled rifles.” An NFA trust, and it is not optional if you want anyone else to be able to possess them lawfully or to inherit them without committing a felony.
“None of the above.” Then you probably do not need anything on this page, and you should be suspicious of anyone telling you otherwise. Most families are well served by a basic plan or a revocable trust.
Meet Derek Haake
He has administered these after the settlor was gone.

Derek spent three years as a Vice President and Estate Settlement Officer at Bank of America Private Bank — the country’s largest provider of managed personal trust services — working with irrevocable trusts long after the person who created them could explain what they meant. Insurance trusts where the Crummey notices had never been sent. Charitable trusts whose payout no longer worked. Dynasty trusts drafted for a tax regime that no longer existed.
Irrevocable trusts are the part of estate planning where a drafting shortcut is permanent, and where the consequences show up decades later in someone else’s hands. That is the perspective he brings to drafting one — and to fixing one, which Missouri’s decanting statute makes possible far more often than people assume.
He holds an MBA alongside his law degree and has spent almost fifteen years litigating trust and fiduciary disputes. Structures get tested, and he has been in the room when they were.
Common questions
Irrevocable trusts in Missouri, answered.
What makes a trust irrevocable, and can it ever be changed?
A trust is irrevocable when the settlor has given up the power to revoke or amend it. In Missouri, RSMo § 456.6-602 presumes a trust executed on or after 1 January 2005 is revocable unless the terms expressly say otherwise — so irrevocability is a deliberate drafting choice. A revocable trust also becomes irrevocable automatically at the settlor’s death.
It can still be changed, more often than people think. Decanting under § 456.4-419 lets a trustee with discretionary distribution authority move the property into a second trust with better terms, on sixty days’ written notice to permissible distributees, provided at least one beneficiary is common to both and no new beneficiaries are added. Missouri strengthened this statute in 2022.
There is also modification by consent of the settlor and beneficiaries, and judicial modification where circumstances have changed in ways nobody anticipated. If you have an old trust that no longer does what it should, it is worth having someone look before assuming nothing can be done.
Can I be the trustee of my own irrevocable trust?
Sometimes, within limits, and it is usually the wrong instinct. The whole benefit depends on you not having retained the powers that would put the property back in your estate.
Retaining the right to income or possession, or the power to designate who enjoys the property, causes inclusion under IRC § 2036. Retaining a power to alter, amend, revoke or terminate causes inclusion under § 2038. For an insurance trust, holding any incident of ownership causes inclusion under § 2042. And for asset protection, RSMo § 456.5-505.3 withholds protection if you retained a power to amend or are the sole beneficiary.
What you generally can retain safely: a testamentary power to appoint among people other than yourself, your estate and your creditors; a power to veto distributions; and, in a grantor trust, a nonfiduciary power to substitute assets of equivalent value under § 675(4)(C). The usual answer is an independent trustee plus a trust protector who can replace them.
How is an irrevocable trust taxed?
Two different regimes, and which one applies is a drafting choice. A grantor trust under IRC §§ 671–679 is disregarded for income tax — you report its income on your own return. That is usually a feature: the trust grows untaxed, and the tax you pay is a further transfer to the beneficiaries that is not treated as a gift.
A non-grantor trust is a separate taxpayer filing Form 1041. Income distributed carries out to beneficiaries and is taxed to them; income retained is taxed to the trust at brackets that compress brutally — the top rate arrives at a level of income that would be unremarkable for an individual.
Separately, whether the assets are in or out of your estate is a different question from who pays income tax. An IDGT is deliberately outside the estate and inside your income tax return at the same time. And remember that estate-excluded assets get no basis step-up at death under § 1014.
Will an irrevocable trust protect me from creditors?
It can, and Missouri is a favorable state for it. RSMo § 456.5-505.3 provides that a spendthrift provision in an irrevocable trust prevents even the settlor’s own creditors from reaching the assets — Missouri has permitted this since the 1980s, well before Alaska and Delaware made the idea famous.
Four conditions must hold: the trust is irrevocable; it contains a spendthrift provision; the transfer was not fraudulent under Missouri’s Uniform Fraudulent Transfer Act, Chapter 428; and when the trust became irrevocable you were not the sole beneficiary of income or principal, did not retain a power to amend, and were not one of a class with a retained right to a specific determinable portion.
The timing rule is the one that matters. Under RSMo § 428.049, an actual-intent fraudulent transfer claim survives for four years after the transfer, or one year after it was or reasonably could have been discovered, whichever is later. Transfers made after a claim exists are not protected. Asset protection is something you do when nothing is wrong.
What is a Crummey power and why does my trust need one?
A gift to a trust is normally a future interest, and future interests do not qualify for the $19,000 annual gift tax exclusion. A Crummey power fixes that by giving each beneficiary a limited-time right to withdraw their share of any contribution — typically thirty days.
That right makes the gift a present interest. Crummey v. Commissioner, 397 F.2d 82 (9th Cir. 1968), held that what matters is the legal right to demand the money, not whether the beneficiary is ever likely to exercise it — and the court applied that even to minor beneficiaries.
The requirement people fail is the paperwork: written notice must actually be sent to each beneficiary each time a contribution is made, and the notices must be kept. Insurance trusts where nobody sent notices for a decade are common, and the annual exclusion for those contributions is at risk. Be cautious too about granting withdrawal rights to remote contingent beneficiaries purely to multiply exclusions — the IRS has litigated that repeatedly.
Should I put my house in an irrevocable trust?
Usually not, and it is one of the more commonly oversold ideas. Three problems.
Basis. A home in an irrevocable trust outside your estate gets no step-up at death under § 1014, so your children inherit your original basis and a capital gains bill on decades of appreciation. The exclusion on sale. The § 121 exclusion of gain on a principal residence can be lost depending on how the trust is structured. Control. You no longer own your home.
The three situations where it does make sense: a Medicaid asset protection trust funded more than five years before you need care; a QPRT for a genuinely taxable estate; and a vacation property being passed to the next generation deliberately.
For everyone else, the goal is usually probate avoidance, and a beneficiary deed under RSMo § 461.025 or a revocable trust achieves it with none of the cost.
How long can a Missouri trust last?
Effectively forever. RSMo § 456.025 disapplies the rule against perpetuities to a trust where the trustee — or another person properly granted the power — has the power to sell the trust property during any period the trust continues beyond the common-law perpetuities period. No rule against unreasonable restraints on alienation is violated either.
The power of sale is the condition, not an afterthought. A dynasty trust holding an asset the trustee cannot sell does not get the benefit. The statute also addresses accumulations, and it applies to trusts created or amended on or after 28 August 2001, plus certain trusts that move to Missouri from a state where the rule did not apply.
Practically, this makes Missouri a viable situs for a multi-generational dynasty trust. Combined with an allocation of GST exemption under IRC § 2631, a trust can grow across generations without a transfer tax at each one.
Do I lose the step-up in basis?
For assets genuinely removed from your estate, yes — and this is the most underweighted cost in the whole category. Under IRC § 1014 the step-up applies to property includible in the gross estate. Property outside it takes carryover basis under § 1015 instead. Rev. Rul. 2023-2 confirmed this for irrevocable grantor trusts.
Do the arithmetic before acting. With the exclusion permanently at $15 million per person, a family that will never owe estate tax gains nothing by removing assets and loses the step-up — converting a 40 percent tax they would not have paid into a capital gains tax their children will.
Where planning is genuinely needed, there are ways to preserve some of it: a swap power under § 675(4)(C) allows you to substitute cash for appreciated trust assets before death, bringing the appreciated property back into your estate for the step-up. That is a real technique, and it depends on drafting the power correctly at the outset.
What does an irrevocable trust cost to set up and run?
More than a revocable trust, and it varies enormously by type. A straightforward ILIT or a third-party special needs trust is at the lower end. A GRAT, an IDGT sale or a charitable remainder trust involves valuation work, actuarial calculations and coordination with your accountant, and sits considerably higher.
Then there is the ongoing cost, which people forget. A non-grantor trust files its own Form 1041 every year. An ILIT needs Crummey notices sent and documented annually. A GRAT needs annuity payments made on schedule and correctly valued. A charitable remainder trust has its own annual return. A trustee may be entitled to compensation. And the trustee owes the reporting duties of RSMo § 456.8-813.
Fees are quoted flat where the scope is knowable, before any work begins. The honest question to ask about any of these is whether the benefit exceeds the lifetime cost of running it — and for many families the answer is no.
Can an irrevocable trust be undone if it was a mistake?
Frequently, yes. Missouri offers three routes, and they are used more often than the word “irrevocable” suggests.
Decanting under § 456.4-419 is the workhorse: a trustee with discretionary distribution authority may pour the trust into a new one with corrected terms, or amend the existing trust directly. Sixty days’ written notice to permissible distributees of both trusts; at least one common beneficiary; no new beneficiaries. Statutory safeguards preserve marital and charitable deductions, GST status, S corporation eligibility, and the position of a beneficiary with a disability.
Consent modification, where the settlor and all beneficiaries agree. Judicial modification, where circumstances have changed in ways the settlor did not anticipate and modification would further the trust’s purposes.
What none of these can do is give the property back to the settlor free of tax consequences. Undoing an estate-tax-motivated transfer generally means the transfer was never effective, with the consequences that follow.
My parents set up a trust years ago. Should someone look at it?
Yes. Old irrevocable trusts are one of the most productive things to review, for four reasons.
The tax landscape changed completely. A trust drafted when the exclusion was $600,000 or $1 million, using a formula clause tied to the exclusion amount, behaves very differently now that the figure is $15 million — sometimes funding a credit shelter trust with the entire estate and leaving a surviving spouse with nothing outright.
The SECURE Act rewrote retirement account trusts. A conduit provision drafted before 2020 may force a full ten-year payout to a beneficiary the trust was meant to protect.
Administration may have lapsed. Crummey notices never sent, annual returns never filed, trustee reports never given — each fixable, and cheaper to fix than to litigate.
The people changed. Named trustees who have died or moved, beneficiaries whose circumstances are unrecognizable. Decanting exists for exactly this.
How do I decide which of these I actually need?
Start with the problem in plain language, not with a product. “My son cannot manage money.” “My estate is $22 million and most of it is the farm.” “I am a surgeon and I am worried about a lawsuit.” “I want my grandchildren to get something without the government taking a bite twice.” Each of those points to a different tool, and several point to no tool at all.
Then be honest about the threshold questions. Are you actually over $15 million, counting life insurance you own? Is the asset really going to grow that much? Is the liability exposure real or theoretical? Would insurance solve it more cheaply?
The consultation is free and it is a real conversation rather than a pitch. A substantial share of the people who come in asking about irrevocable trusts leave with a basic plan or a revocable trust and money still in their pocket. That is a legitimate outcome, and you will be told when it is yours.
Not sure which one?
Bring the problem. The structure comes second.
Twenty minutes, no commitment. Tell us what you are actually worried about — a person, a tax, a lawsuit, a nursing home — and you will get a straight answer about which of these applies, what it costs to run, and whether you need one at all.
