The Charitable Lead Trust (CLAT and CLUT)

By Timothy LeGendre, CPA · Florida License #AC62625 · Published 2026-08-31

How a charitable lead trust pays a charity first and freezes what passes to my client's children, and where a CLAT's zeroed-out design can fail.

How it works

A charitable lead trust reverses the payment order of the charitable remainder trust I write about separately. The charity is paid first, for a term of years or one or more measuring lives, and whatever principal is left at the end passes to a noncharitable remainder beneficiary, usually my client's children or a trust for their benefit. I come back to that mirror-image comparison throughout this page, because much of how this structure gets misunderstood comes from assuming it behaves like its counterpart.

The trust pays in one of two forms. A charitable lead annuity trust, called a CLAT, pays the designated charity a fixed dollar amount each year, a guaranteed annuity determinable at funding (Section 170(f)(2)(B); Treasury Regulation 25.2522(c)-3(c)(2)(vi)(a)). A charitable lead unitrust, called a CLUT, pays a fixed percentage of the trust's value instead, revalued every year (Treasury Regulation 25.2522(c)-3(c)(2)(vii)(a)). The CLAT is the workhorse for a wealth-transfer plan, because a level, determinable annuity is what the zeroed-out design below needs. A CLUT gets used more when a client wants the payout, and the deduction, to float with performance, or when the generation-skipping math needs to run under the ordinary rules instead of the CLAT's own throttled formula, covered further down.

The grantor-versus-non-grantor fork

Every charitable lead trust makes an income-tax election through how it is drafted, not a box checked on a form, and that election is the single biggest decision in the design. A grantor CLT gives my client an upfront deduction under Section 170(f)(2)(B), equal to the present value of what the charity will receive, but only if my client is treated as owner of the entire trust under the grantor-trust rules of Section 671 and following. In exchange, my client reports all of the trust's income, interest, dividends, and gains every year for the whole term, even though none of that cash reaches them; Section 170(f)(2)(C) then denies any further deduction for the trust's own payments to charity once the upfront one is taken, so the same dollars are never deducted twice.

A non-grantor CLT works the opposite way. My client gets no upfront deduction, but the trust becomes its own taxpayer, and Section 642(c) lets it deduct, with no percentage-of-income ceiling, whatever gross income it pays to a Section 170(c) charity that year, sheltering its own income while my client reports nothing. Both versions get the same gift-tax deduction under Section 2522(c)(2)(B), or the estate-tax deduction under Section 2055(e)(2)(B) for a trust created at death, because neither section carries the grantor-trust condition the income-tax deduction does. That is the entire fork: one large deduction paid for with income the trust never hands my client, or no deduction and a trust that carries its own tax load every year. Either way, the value reaching the family is frozen at the same gift-tax cost.

What creates grantor status

The IRS's own safe-harbor forms create grantor status through a Section 675(4) power to substitute trust assets of equal value, held by someone other than my client, the trustee, or a disqualified person under Section 4946(a)(1), exercisable only in a nonfiduciary capacity. It is the same mechanism behind an installment-sale grantor trust built for a different kind of transfer, and exercising the power can itself be self-dealing under Section 4941, so whoever holds it has to be chosen carefully.

The valuation rate and the zeroed-out design

A charitable lead trust is valued using the Section 7520 rate, set monthly at 120 percent of the applicable federal midterm rate. A CLAT wants that rate low, the opposite of what a charitable remainder trust wants: the taxable gift of the remainder equals the amount contributed minus the present value of the annuity promised to charity, and a lower rate makes that annuity worth more, so a smaller payment absorbs the entire gift.

A drafter can push this to its limit and size the annuity so its present value equals essentially the whole amount contributed, driving the taxable gift toward zero. If the trust's actual return then beats the 7520 rate used to size it, everything above that rate passes to the remainder beneficiaries without further gift tax, because the gift was already fixed on the funding date, structurally the same arbitrage behind a GRAT, aimed at a charitable interest instead of a private one. A client who would rather use some lifetime exemption deliberately can size the annuity to leave a partial, not fully zeroed-out, gift instead.

What this is worth in Florida

Florida changes nothing here. There is no state income tax, so the phantom-income cost of a grantor CLT and the ongoing entity-level tax of a non-grantor CLT are purely federal questions, and the estate and gift-tax freeze on the remainder is likewise entirely federal.

Who this applies to

There is no income or entity gate here the way there is for many strategies I write about. Any individual can fund a charitable lead trust during life, and an estate can create one at death. What decides whether this is worth pursuing is whether two things hold at once: a genuine, sizeable charitable intent someone wants to front-load now, and family wealth destined for the next generation that someone is willing to lock inside an irrevocable structure for years.

  • The lead interest has to take a qualifying form. It must be a guaranteed annuity or a fixed percentage unitrust amount, determinable at the gift date and never tied to a fluctuating index. A hybrid interest, such as the lesser of a stated amount or a percentage, fails this definition and does not qualify at all.
  • The income-tax deduction has a gate the gift and estate-tax deductions do not. Section 170(f)(2)(B) allows it only if my client is treated as owner of the trust under Section 671. Neither Section 2522(c)(2)(B) nor Section 2055(e)(2)(B) carries that condition, so a non-grantor trust still freezes the remainder's value with no income-tax break attached.
  • A CLAT faces a qualification cliff a CLUT does not. If the present value of the lead interest exceeds 60 percent of the trust's total value at funding, ordinarily true of an aggressively zeroed-out CLAT, the instrument must expressly prohibit the jeopardizing-investment transactions described in Section 4944, or the whole deduction is denied, not merely exposed to an excise tax. The unitrust-interest definition a CLUT relies on carries no equivalent clause.
  • The trust has to run on a calendar year. Section 644(a) requires it, an administrative gate rather than an election; a fiscal-year instrument is simply invalid.

What it requires

Keeping the instrument itself qualified

Creating grantor status through the substitution power only works if the holder is genuinely someone other than my client, the trustee, or a disqualified person, confined to a nonfiduciary capacity. An inter vivos CLAT, grantor or non-grantor, also has to prohibit any additional contribution once funded; an inter vivos CLUT permits them by default, prorated for the year one is added. A testamentary CLUT flips back to the CLAT rule and must prohibit them.

Filing every year

  • Form 709, or Form 706 for a testamentary trust, claims the deduction for the value of the lead interest.
  • Form 5227 every year the trust exists: the IRS names a charitable lead trust, alongside a charitable remainder trust, as a split-interest trust under Section 4947(a)(2) that owes this filing.
  • Form 1041 as well, for a non-grantor CLT, to pay the trust's own income tax net of its Section 642(c) deduction.
  • Form 4720 for any excise tax due under Section 4941, 4943, 4944, or 4945.

What you need to document

Proof the transfer was actually completed
What was contributed, its fair market value on the funding date, and evidence the trust was properly established before any payment obligation began running.
The instrument's qualifying language, in the document itself
For a CLAT crossing the 60 percent threshold, the jeopardizing-investment prohibition in the trust's own text. A deduction rests on what the document says, not what was intended.
A substitution-power paper trail, for a grantor CLT
Confirmation the holder is not a disqualified person, and a record of any time the power is exercised, since exercising it can itself be self-dealing.
Annual valuation and payment records
For a CLUT, the yearly revaluation setting that year's amount; for either form, proof the payment actually reached the named charity on schedule.
The filing history itself
Copies of the return that claimed the original deduction, every year's Form 5227, and, for a grantor trust, a running record of the income reported in case recapture is ever needed.

Where it goes wrong

A charitable lead trust built on the IRS's own safe-harbor forms is a mainstream, blessed structure, not a listed transaction. Nearly everything that goes wrong is a drafting failure, not a conceptual one.

The 60 percent cliff and the CRT mix-up

A CLAT whose lead interest exceeds 60 percent of trust value, without the express jeopardizing-investment prohibition in its own instrument, does not merely risk an excise tax. The interest never qualifies as a guaranteed annuity interest at all, and the entire deduction fails, a drafting failure that undoes a well-conceived plan through the document's own wording rather than the underlying facts.

Separately, a grantor CLT gives no shelter from capital gain when the trust sells appreciated property it was funded with. My client, as deemed owner, reports that gain personally, exactly as if they still held the asset; a charitable remainder trust's tax-exempt sale has no counterpart here. Only a non-grantor CLT gets any offset, through Section 642(c) with Treasury Regulation 1.643(a)-3(c), and only to the extent the gain funds that year's payment. A client who assumes a lead trust behaves like a remainder trust here is wrong, and I would rather correct that in the engagement letter than after the trust has sold something.

Recapture on a busted grantor trust

If my client stops being treated as the trust's owner before the term ends, say the substitution power lapses or a drafting flaw surfaces, Treasury Regulation 1.170A-6(c)(4) claws back the original deduction. What gets subtracted is the discounted value of what the charity actually received by that point, never the income already reported; those are two different figures, and only one enters the formula. The regulation's own example makes the gap concrete: a donor who had reported $1,500 of trust income over three years, while the church had received a stream discounted to $1,336.51, still owed recapture of $2,064.34, the difference between the original $3,400.85 deduction and that $1,336.51, with the reported income nowhere in the arithmetic.

  • Self-dealing reaches every charitable lead trust, not just the large ones. Unlike Sections 4943 and 4944, there is no 60 percent size exemption for Section 4941 self-dealing or the Section 4945 taxable-expenditure rules. My client and family cannot buy from, sell to, lease to, or borrow from the trust regardless of its size, and drafting a CLAT's contribution rule off a CLUT's default, or the reverse, is a recurring mistake.
  • A CLAT aimed at grandchildren carries a generation-skipping throttle a CLUT escapes. Section 2642(e) grows the exemption allocated at funding only at the 7520 rate, then divides by the trust's actual value when the annuity ends. A CLAT that outperforms its hurdle, its whole design goal, grows that denominator faster than the numerator, so full exemption up front does not guarantee a zero ratio later. A CLUT uses the ordinary allocation rules instead.
  • The shark-fin variant is a narrower approval than it looks. Private Letter Ruling 201216045 blessed a testamentary CLAT whose annuity rose 120 percent of the prior year's payment for ten years, after a probate court construed an ambiguous instrument to permit it. That ruling cannot be cited as precedent by anyone else, the escalation was moderate and court-construed rather than an aggressive drafting choice, and it never addresses an intentionally extreme structure paying almost nothing until a single balloon at the end. I treat an aggressive shark-fin CLAT as unresolved, not blessed.

A situation where this comes up

The client I have in mind already gives significant amounts to charity as a matter of course and has more wealth than the family will ever need, growing faster than they can spend it. They want the charity to see real dollars now rather than a promise at death, and whatever the trust earns above a modest hurdle to end up with their children at as little further gift-tax cost as possible. Getting there means the instrument has to be right before anything is funded: the sizing run off the actual 7520 rate for the funding month, the prohibition language in the document from the start if the lead interest will exceed 60 percent of trust value, and the grantor-versus-non-grantor choice made deliberately.

The version that worries me is one where a zeroed-out CLAT gets proposed and the charity is an afterthought, a mechanism for zeroing out a gift rather than an organization my client actually wants to support. The tax mechanics do not change either way, but a structure built around the wrong motive is the one most likely to have its instrument rushed, its prohibition language missed, or its substitution power handed to the wrong person.

Frequently asked questions

What is a charitable lead trust?
A charitable lead trust is an irrevocable trust that pays a named charity first, for a term of years or someone's lifetime, then passes whatever remains to a noncharitable beneficiary, usually the donor's children. It is the mirror image of a charitable remainder trust, which pays the donor first and a charity last. The two forms are a charitable lead annuity trust, called a CLAT, which pays a fixed dollar amount, and a charitable lead unitrust, called a CLUT, which pays a fixed percentage of trust value.
What is the difference between a CLAT and a CLUT?
A CLAT pays the charity a fixed dollar amount every year, set when the trust is funded; a CLUT pays a fixed percentage of the trust's value instead, recalculated annually, so its payment floats with performance. A CLAT is the more common choice for a wealth-transfer plan because its level payment is what a zeroed-out design needs. A CLUT gets chosen when the payout should float with the portfolio, or when a trust aimed at grandchildren needs the ordinary generation-skipping allocation rules instead of the CLAT's special formula.
Do I get a tax deduction for funding a charitable lead trust?
Only if the trust is drafted as a grantor trust. A grantor charitable lead trust gives an upfront income-tax deduction equal to the present value of what the charity will receive, but the donor then reports all of the trust's income every year for its term, even though that cash goes to charity, not to them. A non-grantor trust skips the upfront deduction, and the trust itself deducts its own charitable payments instead, so the donor reports nothing along the way.
What happens if a charitable lead trust outperforms its target rate?
Everything the trust earns above the rate used to size its annuity passes to the remainder beneficiaries without any further gift tax, because the taxable gift was fixed on the day the trust was funded and is never recalculated later. This is the core of the wealth-transfer design: a drafter sizes the annuity so its present value absorbs nearly the entire contribution, pushing the taxable gift toward zero, so any return above the assumed rate becomes pure upside for the family.
Is a charitable lead trust the same as a charitable remainder trust?
No, they are opposites. A charitable remainder trust pays the donor first and a charity receives what is left; a charitable lead trust pays the charity first and a noncharitable beneficiary, usually the donor's children, receives what remains. The two also suit different goals: a charitable remainder trust fits someone who wants income now, while a charitable lead trust fits someone who wants to make a large charitable gift now while moving future growth to family at a reduced gift-tax cost.
What is a shark-fin CLAT?
A shark-fin CLAT concentrates its payments to charity in the final years instead of spreading them evenly, letting more money compound inside the trust early while the structure still zeroes out the taxable gift on paper. One private letter ruling blessed a moderate version, an annuity that rose gradually each year after a probate court construed an ambiguous trust document that way. It never addressed an aggressive version, and a private ruling cannot be cited as precedent by anyone else.
