How a charitable lead annuity trust works
A charitable lead annuity trust (CLAT) is an irrevocable trust with two sets of beneficiaries. For a term you choose (a fixed number of years, or one or more lifetimes), the trust pays one or more charities a fixed annuity amount every year. When the term ends, whatever is left goes to the people you name, usually children or a trust for them, or in some designs back to you.
The annuity is set on day one as a dollar amount or a fixed percentage of the starting value. It does not move with investment results. That is the whole engine of the tool: the IRS values the charity's stream using the Section 7520 rate in effect when you fund the trust. If the trust's actual return beats that rate, the extra growth lands with the remainder beneficiaries. If it falls short, the charity still gets its fixed payments and the family gets less, sometimes nothing.
The IRS has published annotated sample trust forms for inter vivos CLATs in Rev. Proc. 2007-45, so the structure itself is well mapped. The real decision is which of two tax flavors you want.
Grantor CLAT vs non-grantor CLAT
Grantor CLAT: a deduction now, taxable income later
If the trust is drafted so you are treated as its owner under the grantor trust rules (IRC 671 to 679), IRC 170(f)(2)(B) gives you an income tax deduction in the funding year equal to the present value of the charity's annuity stream. That is the attraction for a seller: a large deduction can land in the same year as a large gain.
The trade is that you then report all of the trust's income, gains included, on your own return every year of the term, with no further charitable deduction when the trust pays the charity. If you stop being treated as the owner before the term ends, the statute recaptures part of the original deduction as income.
Non-grantor CLAT: a smaller taxable gift
If the trust is its own taxpayer, you get no upfront income tax deduction. Instead, the trust deducts the amounts it pays to charity under IRC 642(c), and the main benefit is on the gift tax side: IRC 2522(c)(2)(B) allows a gift tax charitable deduction for the present value of the annuity. Size the annuity so that value nearly equals what you put in (a so-called zeroed-out CLAT) and the taxable gift of the remainder is close to zero. Growth above the Section 7520 rate then passes to heirs without using more of your lifetime exemption. A CLAT created at death works the same way under IRC 2055(e)(2)(B).
Who it fits, and who it does not
Good fit:
- A seller with a one-time spike in income who already plans to give meaningful amounts to charity over the next 10 to 20 years and would like the deduction in the high-income year (grantor CLAT).
- A family with assets expected to grow faster than the Section 7520 rate that wants to move that growth to children or grandchildren at a low gift tax cost (non-grantor CLAT).
- Someone who does not need the income from the funded assets during the term.
Poor fit:
- A seller who needs the sale proceeds for retirement income. The charity, not you, is paid first.
- Anyone without real charitable intent. The annuity is a binding obligation for the full term.
- Portfolios expected to earn less than the Section 7520 rate. The family remainder can shrink to nothing.
- A grantor who cannot comfortably pay income tax on trust earnings for years without any matching cash.
Worked example (qualitative)
Assumptions, labeled: a married couple sells a business in 2026 and recognizes a large long-term gain. They itemize, they are in the top bracket that year, and they already give to the same three charities every year. They are weighing a 15-year grantor CLAT funded with cash after closing.
- Funding year. They transfer cash to the CLAT. Because they are treated as owners, they claim a deduction equal to the present value of 15 years of annuity payments, valued at that month's Section 7520 rate. Gifts of an income interest count as gifts "for the use of" a charity (Treas. Reg. 1.170A-8(a)(2)), so the lower 30 percent of contribution base ceiling applies (20 percent if the trust is funded with appreciated capital gain property), with a five-year carryforward for the excess.
- 2026 haircuts. Under the One Big Beautiful Bill Act, only charitable contributions above 0.5 percent of the contribution base count (IRC 170(b)(1)(I)), and for taxpayers in the 37 percent bracket, IRC 68 trims itemized deductions by 2/37 of the lesser of those deductions or the income above the 37 percent bracket start, which caps the benefit near 35 cents per dollar.
- During the term. The trust pays the charities the fixed annuity each year. The couple reports the trust's dividends, interest and gains on their own return with no further deduction.
- End of term. Whatever is left passes to the named remainder beneficiaries. Because this is a grantor CLAT, the remainder is also a gift for gift tax purposes, valued at funding.
We do not put dollar figures on this example because the result turns on the Section 7520 rate in the funding month, the term, the annuity amount and actual investment returns. The Big Sale Tax Analysis runs those with your real inputs.
Using a CLAT around a sale
A CLAT is not a gain deferral device. Fund it with appreciated property and then sell inside the trust, and the gain is still taxed: to you if it is a grantor CLAT, to the trust if it is not. A non-grantor CLAT can offset gain only to the extent the trust instrument directs payments to charity out of that gross income and the payments are actually made (IRC 642(c) and Treas. Reg. 1.642(c)-3).
Many sellers simply fund the CLAT with cash after closing. That keeps the deal clean, avoids appraisal questions, and still puts the deduction in the sale year if the trust is a grantor CLAT.
If you are being paid on an installment note, be careful about moving the note itself. Giving away an installment obligation is generally a disposition under IRC 453B that accelerates the deferred gain. A transfer to a trust you are treated as owning for income tax purposes generally is not, because you are still the owner for tax purposes. Have your CPA confirm the treatment before you move a note.
IRS stance and audit risk
A properly drafted CLAT is a long-standing, Code-sanctioned tool. It is not a listed transaction or a transaction of interest. (Do not confuse it with the charitable remainder annuity trust arrangements Treasury finalized as listed transactions in July 2026; see our charitable remainder trust analysis.)
Where CLATs draw scrutiny:
- Drafting defects. The annuity must be a fixed, determinable amount. Using the IRS sample forms reduces this risk.
- Valuation. Funding with closely held stock or real estate requires a qualified appraisal, and overvaluation inflates the deduction.
- Self-dealing. Split-interest trusts are subject to the private foundation self-dealing rules under IRC 4947(a)(2) and IRC 4941. Leasing trust property to your company or lending to family members can trigger excise taxes.
- Recapture. For a grantor CLAT, losing grantor status before the term ends triggers recapture under IRC 170(f)(2)(B).
Costs and fees
- Attorney drafting of the trust agreement, plus a gift tax return (Form 709) in the funding year.
- A qualified appraisal if you fund with anything other than cash or publicly traded securities.
- Annual trust returns: Form 1041 and the split-interest trust information return, Form 5227.
- Trustee and investment management fees for the full term.
- For a grantor CLAT, the ongoing income tax you pay on trust earnings is a real cost of the deduction you took up front.
How it compares with a Section 453 installment sale
A Section 453 installment sale spreads the recognition of your gain over the years you are paid, so less of it lands in high brackets and more of it can be taxed at lower rates. You keep the principal and the interest. A CLAT does the opposite job: it gives some value away to charity in exchange for a deduction or a smaller taxable gift.
| Section 453 installment sale | Grantor CLAT | |
|---|---|---|
| Gain on the sale | Recognized as principal is collected | Recognized when the asset is sold |
| Who keeps the money | You | Charity during the term, heirs or you after |
| Main risk | Buyer credit (secured by collateral and note terms) | Returns below the Section 7520 rate; tax on trust income |
| Best use | Spreading tax on a big sale | Offsetting a big income year while funding planned giving |
They can work together. An installment sale smooths the gain; a grantor CLAT funded in the year with the largest principal payment can absorb part of that year's income. The $5,000 Big Sale Tax Analysis models this path side by side with a Section 453 installment sale and the other options, so you see the after-tax result of each before you sign anything.
What to know
A CLAT trades current dollars for a deduction or a gift tax discount, and it only makes sense if you want the charity to receive those payments. The annuity is fixed for the whole term regardless of markets, so weak returns can leave little for your family. A grantor CLAT front-loads the deduction but leaves you paying tax on trust income for years. 2026 rules (the 0.5 percent floor and the 35 percent benefit cap in the top bracket) also trim the deduction for high earners.
