What the strategy is, in one sentence

• Name a qualified charitable remainder unitrust (CRUT) as the death beneficiary of a traditional IRA, so the account pays into a tax-exempt trust that then meters a payout to a child or other individual over a life or a term of up to 20 years, with the remainder to charity. The objective is to soften the income-tax compression the SECURE Act 10-year rule creates for a non-eligible designated beneficiary.

The mechanics are sound; three of them are routinely misunderstood

• The trust is tax-exempt, so the IRA pours in untaxed. A qualified CRT pays no income tax under § 664(c) when the IRA distributes to it. The full pre-tax balance keeps compounding inside the trust. This part of the pitch is correct.

• The "stretch" comes from the trust's payout schedule, not from stretching the IRA. The IRA itself may be emptied into the CRUT quickly; that is harmless because the trust is exempt. The deferral is manufactured by the unitrust payout, which can run far longer than ten years.

• The income that comes out is not converted to capital gain. Under the four-tier "worst-in, first-out" ordering of § 664(b), the IRA's ordinary income sits in the first tier and must be fully distributed before any preferentially taxed dollars reach the beneficiary. The CRUT defers and smooths ordinary income; it does not transform it.

The constraints that govern qualification and fit

• A CRUT must pay between 5% and 50% annually, and the present value of the charitable remainder must be at least 10% of the funding value. The 5% floor means you cannot replicate the sub-2% required distribution a very young stretch beneficiary used to take.

• The 10% test, run under the § 7520 rate and the 2010CM mortality table, sets a practical minimum beneficiary age for a lifetime CRUT — generally the late 20s. Younger beneficiaries fail and must use a fixed term of 20 years, which buys only ten years beyond the SECURE Act baseline.

• For this use, the CRUT, not the CRAT, is the vehicle. A lifetime CRAT for a young beneficiary cannot clear the 5% probability-of-exhaustion test of Rev. Rul. 77-374.
  

The short answer. The technique is legitimate and well supported, but it is a charitable strategy that produces income smoothing as a by-product — not a wealth-maximization tool. It earns its keep only when three things are true at once: a large traditional (not Roth) IRA, a high-bracket beneficiary old enough to clear the 10% test yet young and healthy enough to reach the multi-decade break-even, and genuine pre-existing intent that a substantial sum reach charity. Where the remainder to charity is a feature, the structure is elegant. Where it is a bug, do not use it.

Executive Summary

The SECURE Act replaced the life-expectancy "stretch" for most non-spouse beneficiaries with a rule that empties an inherited IRA within ten years. IRC § 401(a)(9)(H). For a beneficiary in peak earning years, a large traditional IRA distributed across that window stacks ordinary income on top of wage income and can push the marginal dollar into the top federal bracket plus state tax. The planning question is whether the compression can be relieved without simply surrendering the asset.

A charitable remainder unitrust answers part of that question. Because a qualified CRT is tax-exempt under § 664(c), naming it as the IRA beneficiary lets the entire pre-tax balance arrive in the trust without an income-tax event, after which the trust pays a unitrust amount to an individual for life or a term of up to 20 years and distributes the remainder to charity. Because the charitable remainder trust is a tax-exempt entity under IRC § 664, the entire lump-sum distribution of the retirement account balance to the trustee is received without income tax, and the trust is then required to distribute a percentage of the trust assets to one or more individual beneficiaries for life or for a term of up to twenty years. The deferral is real, and for a high-bracket heir the bracket smoothing can be meaningful.

Three features temper the enthusiasm a lunch-seminar version of this idea tends to generate. First, the character of the distributions is unfavorable: all of the retirement account that is paid to the charitable remainder trust is characterized as ordinary income, and the § 664(b) tier rules push that ordinary income out first, so the beneficiary sees ordinary-income tax on essentially every dollar for the first two to three decades. Second, the 10% remainder test, run under a § 7520 rate that cannot be known until the date of death, imposes a minimum beneficiary age for a lifetime trust. Because it is impossible to know in advance the Section 7520 rate that will exist at the time of death, CRUTs generally should not be considered for use until the intended beneficiary is at least 27 or 28 years old. Third, and most fundamentally, the remainder belongs to charity, not the family, and on an early death the charity receives a windfall while the heirs lose most of the principal.

The honest verdict is that this is an estate-and-charitable design that happens to defer tax, not a loophole that beats a direct inheritance for the family. For a fixed-period CRUT, whose maximum term is only 20 years, it is virtually impossible to pass more wealth to an heir than naming them directly on the beneficiary form, because the funds are distributed too quickly for tax deferral to overcome the requirement that at least 10% of the trust pass to charity. A lifetime trust can do better, but only after a break-even measured in decades. The sections below develop the mechanics, the actuarial constraints, the economics against the obvious alternative, and the fact patterns where the strategy is the right answer.

The Strategy and Its Moving Parts

The SECURE Act baseline the strategy is reacting to

For deaths after 2019, a non-eligible designated beneficiary — typically an adult child who is not disabled, not chronically ill, and not within ten years of the decedent's age — must distribute the entire inherited IRA by the end of the tenth year following death. IRC § 401(a)(9)(H); IRS Pub. 590-B. Where the owner died after the required beginning date, final regulations also require annual distributions in years one through nine. The result for a $2,000,000 traditional IRA is a decade of forced ordinary income layered on a high earner's existing income — the "tax compression" the strategy is built to relieve.

Why the CRT escapes the ten-year rule

A trust is not an individual and therefore is not a "designated beneficiary" subject to the ten-year payout. A qualified CRT is, in addition, tax-exempt under § 664(c). Naming the CRT on the IRA beneficiary form means the IRA pays into the trust — possibly all at once — with no income tax at the trust level, and the pre-tax balance then compounds inside the exempt trust while the unitrust amount is paid out to the individual over a far longer horizon. A charitable remainder trust, whether the annuity version (a CRAT) or the unitrust version (a CRUT), is required to distribute a percentage of the trust assets to one or more individual beneficiaries for life or for a term of up to twenty years. A beneficiary in their forties on a lifetime CRUT can therefore receive distributions across thirty or forty years rather than ten.

The four-tier trap: worst-in, first-out

This is the feature the strategy's enthusiasts most often omit, and it is decisive. CRT distributions carry out income by character under a fixed ordering, Treas. Reg. § 1.664-1(d):

0. Ordinary income, including undistributed ordinary income from prior years

1. Capital gain

2. Other income, including tax-exempt income

3. Return of corpus

The trust must distribute the worst-taxed tier first. A traditional IRA is income in respect of a decedent under § 691 — pure ordinary income with no basis step-up under § 1014(c). The entire $2,000,000 entering the trust therefore lands in Tier 1 and must be fully paid out before a single dollar of the trust's own investment gain reaches the beneficiary at capital-gain rates. The gain is metered out through the § 664 tiers over the payout years. For a young beneficiary, that means ordinary-income treatment on virtually every distribution for the first twenty to thirty years.

A simple illustration: a $2{,}000{,}000$ IRA funds a 5% CRUT paying roughly $100{,}000$ in year one, growing modestly. Ignoring fresh interest and dividends generated inside the trust, cumulative payments do not exhaust the original $2{,}000{,}000$ of Tier 1 ordinary income until somewhere around year 17 — and ongoing ordinary income earned inside the trust extends that period. The takeaway is blunt: the CRUT spreads and smooths the IRA's ordinary income across brackets and years, but it never converts it into the lightly taxed capital gain that a brokerage account would eventually deliver. Anyone selling the structure as a capital-gains play has the law wrong.

Age and the Actuarial Tests

The payout band and why the floor matters

A CRUT must pay at least 5% and not more than 50% annually, and the present value of the charitable remainder must be at least 10% of the value contributed. The 5% floor is the quiet constraint. A 45-year-old's first-year required distribution under the old stretch was roughly

$$\frac{1}{41.0} \approx 2.44\%,$$

so the CRUT's mandatory minimum is about double the old-stretch starting draw. The "smoothing" is therefore less generous than a true stretch: more taxable income is forced out earlier than the life-expectancy rule would have required.

The 10% test, the § 7520 rate, and the minimum age

The 10% remainder test of § 664(d)(2)(D) is computed under the § 7520 rate for the funding month (with an election to use either of the two prior months) and the 2010CM mortality table of Treas. Reg. § 1.664-4. For a CRUT the remainder behaves like one minus the adjusted payout rate, compounded over the expected number of payout years; fewer expected years means a larger remainder and easier qualification. The dominant variables in a CRUT remainder calculation are the payout rate, the term, and, for life-contingent trusts, the beneficiary's age.

The practical consequence is a floor on the beneficiary's age for a lifetime trust. A long expectancy depresses the remainder; at a low enough § 7520 rate, a 5% lifetime CRUT for a beneficiary in their early twenties cannot leave 10% to charity and simply fails to qualify. Because the 10% minimum remainder rule limits certain combinations of age, payout rate, and § 7520 rate, and because the rate on the future date of death is unknowable, the conservative drafting convention is the one Kitces states directly: CRUTs generally should not be considered until the intended beneficiary is at least 27 or 28 years old, and term-payout CRUTs using a fixed number of years instead of the beneficiary's life expectancy can be established for younger beneficiaries.

A note on the rate itself: the § 7520 rate moves monthly, and a static article cannot responsibly print a "current" value. Run the test against the live rate for the funding month — the CalCRUT IRS 7520 Rate tracker maintains the current and two preceding months — rather than against a figure quoted in any briefing.

CRUT versus CRAT for this purpose

For replacing the stretch, the unitrust is the vehicle and the annuity trust generally is not. A CRUT pays a fixed percentage of the annually revalued trust, so payments and the eventual remainder track the portfolio and provide an inflation hedge, and the CRUT faces no exhaustion test. A CRAT pays a fixed dollar amount and must additionally satisfy the 5% probability-of-exhaustion test of Rev. Rul. 77-374; for a lifetime payout to a young beneficiary that test is effectively impossible to pass in ordinary rate environments. At funding, the present value of the charitable remainder must be at least 10% of the value contributed, a CRUT payout may not exceed 50%, and a CRAT must additionally satisfy the 5% probability-of-exhaustion test. A CRAT earns consideration only for a short fixed term where a predictable dollar amount is the explicit goal.

The Economics Against the Obvious Alternative

The correct comparison is not "pay enormous tax now" versus the CRUT. It is the CRUT versus taking the IRA over the ten-year window, paying the tax, and reinvesting the after-tax proceeds in a taxable account the family fully controls.

Modeled illustratively for a $2{,}000{,}000$ IRA, a 45-year-old beneficiary, roughly 6–7% returns, a ~45% combined ordinary rate, and a 5% lifetime CRUT, three things emerge:

• On a long life (to or beyond life expectancy), the CRUT can leave the heir comparable to — and on favorable assumptions modestly more than — the direct route, but only after a break-even measured in decades, commonly into the beneficiary's late sixties or seventies.

• The charity separately receives a large remainder, frequently $3{,}000{,}000$ or more on a growing trust — principal the family permanently forgoes. So the structure does not leave the total family with more; it redirects a substantial slice to charity.

• On an early death, the result is severe: the direct route leaves the family far ahead, while the charity takes the bulk of the principal and the heirs receive only the few years of payouts that ran.
  

For a fixed-term CRUT the verdict is sharper still. Because the maximum term is only 20 years, it is virtually impossible for a fixed-period CRUT to pass more wealth to an heir than naming them directly on the beneficiary form — the funds are distributed too quickly for tax deferral to overcome the requirement that at least 10% of the CRUT pass to charity. Two structural disadvantages compound the picture: the direct-investment route hands heirs full liquidity plus a basis step-up on the taxable account at the beneficiary's death, while the CRUT remainder simply passes to charity; and although the IRA never carried a step-up to lose, the CRUT does not create the future step-up the taxable account would.

A 20-year fixed term does buy higher annual payouts and routes the balance to heirs on an early death. A CRUT established to make distributions for a 20-year term rather than for life can carry a maximum annual distribution rate of about 11.093% of trust assets regardless of the beneficiary's age. But as a wealth-transfer tool that ten-year extension rarely beats a direct inheritance.

Summary Table: The CRUT-as-IRA-Beneficiary Strategy Across the Dimensions That Matter

Governing Framework

The exemption and the pour-in

A qualified CRT is generally exempt from income tax under § 664(c)(1), which is what lets the IRA distribute into the trust without an income-tax event. The IRA balance is income in respect of a decedent under § 691; in the hands of an individual beneficiary it would be fully taxable ordinary income, but paid to the exempt trust it is received untaxed and retained as Tier 1 ordinary income for later metering. Note that the § 691(c) deduction for estate tax attributable to IRD, available to an individual recipient of IRD, does not flow cleanly through a testamentary CRT and should not be assumed in the model.

The tier rules and why character is unfavorable

Section 664(b) and Treas. Reg. § 1.664-1(d) impose the worst-in, first-out ordering across the four tiers. The trust carries the IRA's ordinary-income character indefinitely and distributes it ahead of any capital gain or tax-exempt income the trust later earns. This is the mechanism that denies the beneficiary capital-gain treatment for many years and distinguishes an IRA-funded CRUT from one funded with appreciated stock, where the gain itself populates Tier 2.

The qualification tests and the payout band

Section 664(d)(2) fixes the unitrust requirements: a payout of at least 5% and not more than 50%, a term measured by one or more lives in being at funding or a fixed term not exceeding 20 years, and a charitable remainder whose present value is at least 10% of the funding value, tested under § 7520 and the actuarial tables of Treas. Reg. § 1.664-4. For a CRAT, Rev. Rul. 77-374 adds the 5% probability-of-exhaustion test, with Rev. Proc. 2016-42 supplying an alternative qualified-contingency route — a concern that does not arise for the CRUT used here.

The charitable and estate-tax overlay

The remainder must pass to an organization described in § 170(c). In the testamentary IRA-beneficiary posture there is no income-tax charitable deduction to the IRA owner — that is a lifetime-funding feature — though the estate may claim an estate-tax charitable deduction under § 2055 for the present value of the remainder, which matters only to a taxable estate. The remainder organization can be a public charity, a private foundation, or a donor-advised fund named by its correct legal name, the last of which preserves family involvement in the eventual charitable dollars.

Strategic Implications for Practice

Diagnose charitable intent before anything else. The remainder belongs to charity, and realistically it exceeds the 10% floor by a wide margin. If the family's goal is to maximize what reaches descendants, the structure is the wrong tool and a direct beneficiary designation, possibly paired with lifetime Roth conversions by the owner, will usually win. Reach for the CRUT only where a substantial charitable gift was already intended.

Confirm the asset is a traditional IRA, not a Roth. A Roth inherited directly delivers up to ten years of tax-free growth and tax-free distributions; routing it through a CRUT trades that away for a charitable remainder and reintroduces taxable tiers on the trust's own income. The strategy is built for pre-tax IRD assets, which are precisely the dollars one most wants to send to charity.

Match the period to the beneficiary's age and the goal. A healthy beneficiary in the late twenties through fifties who needs lifetime smoothing points to a lifetime CRUT, subject to the 10% test clearing at the target payout. A beneficiary too young to qualify a lifetime trust, or a family that wants a guaranteed floor to heirs, points to a 20-year term. An older or unhealthy beneficiary is a poor candidate in either form, because the break-even arrives too late and early-death risk dominates.

Run the 10% test against the funding-month rate and draft for rate uncertainty. Because the § 7520 rate on the date of death is unknowable, a fixed payout drafted today can fail at funding. Drafting the payout as a formula that self-adjusts to satisfy the 10% test at whatever rate prevails is the standard defense. The CalCRUT Deduction Calculator runs the test for typical configurations, and the CRUT Payout Path tool models how the income stream and the remainder evolve under each period.

Price the mortality risk explicitly, and consider mitigation. A lifetime CRUT on an early death hands the charity a windfall and the family little. A 20-year term floor, or pairing the CRUT with a wealth-replacement life-insurance trust where the beneficiary is insurable, can address it — but only where the policy economics pencil out.

Model the whole picture, including state tax and administration. Some states tax CRTs notwithstanding the federal exemption. The trust requires drafting, a trustee, annual Form 5227, K-1s, tier accounting, and valuations; on a modest IRA those costs swamp the benefit. Watch unrelated business taxable income, which can trigger excise tax — avoid debt-financed and operating-partnership investments inside the trust.

Practice Notes

Intake questions for the IRA-to-CRT decision

• Did the family already intend a substantial charitable gift, or is the charity being introduced solely to manufacture deferral?

• Is the asset a traditional IRA (good candidate) or a Roth (generally not)?

• How large is the IRA, and is it large enough to absorb trust administration cost?

• What is the beneficiary's age and health, and is the beneficiary old enough to clear the 10% test on a lifetime trust yet young and healthy enough to reach the break-even?

• Is the beneficiary in a high bracket and a high-tax state, and is relocation to a no-tax state contemplated that the deferral could capture?

• Does the family need liquidity or principal access that the rigid unitrust payout would deny?

Drafting and design checklist

• IRA beneficiary designation names the CRT by correct legal form, coordinated with the trust instrument

• Period drafted as a life or lives, or a term not exceeding 20 years, under § 664(d)(2) and Treas. Reg. § 1.664-3(a)(5)

• Payout set between 5% and 50%, with the 10% remainder test run and documented at the beneficiary's age, target payout, and the funding-month § 7520 rate — ideally via a self-adjusting formula payout

• For a too-young beneficiary, a 20-year term substituted for a lifetime measure, with recognition that it extends the SECURE Act baseline by only ten years

• Mortality risk addressed by a term floor or a separately analyzed wealth-replacement policy

• Remainder beneficiary identified — public charity, private foundation, or a donor-advised fund named by legal name for continued family involvement

• State income-tax treatment of the trust confirmed; UBTI-generating investments excluded

• No reliance placed on an income-tax charitable deduction (unavailable in the testamentary posture) or on a § 691(c) deduction flowing through the trust

Red flags during design

• The structure proposed for a family with no genuine charitable intent, as a pure wealth-transfer play

• A Roth IRA routed through a CRUT

• The strategy sold as converting IRA ordinary income into capital gain, ignoring the Tier 1 worst-in, first-out ordering

• A lifetime CRUT drafted for a beneficiary too young, or too old and unhealthy, to make the economics work

• A fixed payout drafted today with no formula adjustment for the unknown § 7520 rate at death

• A CRAT proposed for a lifetime payout to a young beneficiary, where Rev. Rul. 77-374 will defeat qualification

• A modest IRA burdened with full trust administration cost
  

This briefing is provided for educational purposes and reflects federal law as of June 2026. It does not constitute legal or tax advice. Using a charitable remainder unitrust as the beneficiary of a traditional IRA interacts with the beneficiary's age and health, the target payout rate, the § 7520 rate at funding, the family's charitable intent, and state income-tax treatment of the trust, and the qualifying and advisable structure depends on specific facts not addressed in this general treatment. Consult qualified legal and tax counsel before naming a CRT as a retirement-account beneficiary.

Weighing whether a charitable remainder unitrust should receive your IRA? The decision turns on charitable intent, the beneficiary's age and health, and an actuarial test that must clear on the date of death.
