Charitable Lead Annuity Trust (CLAT): 2026 Guide & Calculator

A charitable lead trust is the structural inverse of a charitable remainder trust. In a CRT, you keep the income and charity gets the remainder. In a CLAT, charity receives an annuity payment for the trust's term, and your heirs receive whatever remains at the end — potentially free of gift and estate tax. The strategy combines philanthropic intent with aggressive wealth transfer, and at May 2026's §7520 rate of 5.00%, it still works for the right assets.

How a charitable lead annuity trust works

You transfer assets irrevocably to a CLAT. For a fixed term of years, the trust pays a fixed annuity to one or more qualified charities.¹ At the end of the term, the remaining trust assets pass to your named remainder beneficiaries — typically children or a dynasty trust for grandchildren and beyond.

The gift tax mechanics: the IRS values the charitable "lead" interest at the present value of all annuity payments using the §7520 rate in effect at the trust's creation. You receive a gift tax charitable deduction (IRC §2522) equal to that present value. The taxable gift to remainder beneficiaries equals the contribution amount minus the charitable deduction.

For a zeroed-out CLAT, you set the annuity payment high enough that the charitable deduction equals the entire contribution — taxable gift = $0. If the trust then outperforms the §7520 hurdle rate, the surplus accumulates and passes to heirs tax-free at term end.

CLAT vs. CLUT — which type fits your situation?

For wealth-transfer-focused planning, the CLAT (annuity trust) is almost always preferred. The remainder of this guide focuses on CLATs.

Grantor vs. non-grantor CLAT — the income tax fork

This distinction matters enormously for the economics of the trust.

Grantor CLAT

The grantor is treated as owner of the trust for income tax purposes. At funding, you receive an income tax charitable deduction equal to the present value of all annuity payments to charity — for a zeroed-out CLAT, that's equal to the contribution amount.² Subject to 30% of AGI limit (appreciated property funded to a public-charity CLAT); unused deduction carries forward 5 years.

The catch: every year, you pay income tax on all trust income — including the portion the trust pays out to charity. In a zeroed-out CLAT funded with $5M, you might receive a $5M income tax deduction upfront but pay income tax on $500K+ of annual trust income for 10 years, even though that income goes straight to charity. The grantor CLAT makes sense when:

• The grantor has high income in the funding year and needs a large deduction now
• The trust holds low-income-producing assets (appreciated stock, real estate) that minimize ongoing grantor income tax drag
• The grantor has significant carryforward losses to offset future income

Non-grantor CLAT (most common)

No income tax deduction for the grantor at funding. The trust pays its own income taxes each year (under the compressed trust income tax brackets, which hit 37% quickly), and deducts its charitable distributions under IRC §642(c) — meaning the trust pays no net tax on income it passes to charity. The grantor avoids the ongoing income tax exposure of a grantor CLAT.

In most wealth-transfer-focused CLATs, the non-grantor structure is preferred: no upfront deduction, but far simpler income tax administration and no risk of large ongoing tax bills on income you don't keep.

The §7520 hurdle rate — why it's the key variable

The §7520 rate for May 2026 is 5.00% (IRS Rev. Rul. 2026-9).³ This rate is both the valuation rate for the charitable deduction and the implicit hurdle rate the trust must beat to pass value to heirs.

Here's the intuition: a zeroed-out CLAT sets the annuity so that if the trust earns exactly the §7520 rate, the charity payments fully exhaust the trust — remainder = $0. Every percentage point of return above 5.00% compounds into a tax-free remainder for your heirs.

Compare to 2020-2021, when §7520 rates dipped to 0.4%. A zeroed-out CLAT at 0.4% needed to pay almost nothing to charity each year — even a modest 5% return passed nearly the full contribution to heirs. At today's 5.00%, CLATs require genuine outperformance to generate a meaningful remainder. They remain powerful for the right assets, but are no longer as broad-based a strategy as they were at near-zero rates.

When a CLAT makes sense

At the May 2026 §7520 rate of 5.00%, CLATs work best under these conditions:

• High-growth assets. Pre-IPO equity, venture fund interests, private real estate, closely held business stakes — assets with realistic 8–15%+ annualized return projections. Public equities at 7–8% expected return produce modest remainders and thin margin for error.
• Genuine philanthropic intent. A zeroed-out CLAT on $5M over 10 years pays $6–7M to charity. If the philanthropic giving is valuable in its own right and the heir transfer is a bonus, the strategy makes sense. If you'd rather keep all the assets, use a GRAT.
• Large estate ($30M+ or state estate tax exposure). With the $15M federal exemption now permanent (OBBBA), a CLAT's zero-gift-tax transfer is especially useful for families already at or above exemption. It depletes the estate without using any exemption.
• Families wanting to give to charity systematically over a term. The CLAT provides a predictable charitable stream — useful for families who want to fund an existing foundation, donor-advised fund, or specific charity over a defined period.
• Income tax planning year (grantor CLAT only). A large income year — business sale, large bonus — can justify a grantor CLAT for the upfront deduction, provided the grantor can absorb the ongoing income tax drag.

When a CLAT does NOT make sense

• When the family needs access to assets during the trust term (CLATs are irrevocable; no distributions back to the grantor)
• When the primary goal is avoiding capital gains on a sale (use a CRT instead — the CRT does this; a CLAT does not)
• When there's no real philanthropic intent (use a GRAT, which transfers appreciation without requiring charity)
• When the asset is conservatively managed and unlikely to beat 5%+ (consider whether a dynasty trust or annual gifting is more appropriate)

CLAT vs. comparable strategies

Best assets for a CLAT

The CLAT's performance depends entirely on the trust beating the §7520 hurdle. The best assets:

• Pre-IPO equity or founder's shares — high growth potential, often held longer-term anyway. A CLAT creates a structured holding period with a charitable outcome at the end.
• Private equity or venture fund interests — high expected returns, though liquidity is a constraint for funding annuity payments if the fund doesn't distribute early.
• Closely held business interests — can be combined with an installment sale or IDGT strategy. Valuation discounts (FLP/LLC) can reduce the funding value, making the zeroed-out annuity smaller.
• Real estate — income-producing properties can naturally fund annuity payments from rental cash flow.
• Avoid: low-yield bonds, balanced portfolios, or anything unlikely to beat 5% consistently over the trust term.

Liquidity: funding the annuity payments

Unlike a GRAT — which pays annuity to the grantor (who can use cash to make payments or accept in-kind trust distributions) — a CLAT pays charity. The trust itself must generate enough cash or distribute-in-kind to the charity each year. For illiquid assets (private equity, real estate), this is a real constraint. Common solutions:

• Fund with income-producing real estate and use rent to make charity payments
• Fund partially with cash or liquid securities alongside the illiquid asset
• Use a "shark fin" CLAT structure (very low early payments that ramp up steeply in later years) to align with expected liquidity events — but these are complex and require careful IRS guidance compliance

Post-OBBBA context: who still needs a CLAT in 2026?

The One Big Beautiful Bill Act (July 2025) made the $15M federal estate/gift/GST exemption permanent and indexed to inflation from 2027.⁴ This removed the "use it or lose it" urgency around gifting and irrevocable trusts for estates below $15M per individual. But CLATs remain highly relevant for:

• Estates over $30M (per couple). The $15M federal exemption covers two spouses' exemptions. Estates above that face 40% federal estate tax. A zeroed-out CLAT moves additional appreciation outside the estate with zero exemption cost — it doesn't compete with the SLAT, dynasty trust, or annual gifting strategy, it supplements them.
• State estate tax exposure. Twelve states and DC impose estate tax at $1M–$7M exemptions — far below the $15M federal threshold. A CLAT removes assets from state estate tax exposure on the same logic.
• Philanthropic families at any wealth level. For families who want to fund charitable causes over time and pass residual wealth to heirs, a CLAT integrates both goals in one structure.
• High-income years requiring large charitable deductions (grantor CLAT). A business sale or large liquidity event can justify a grantor CLAT specifically for the income tax deduction offset.

5 common CLAT mistakes

1. Funding with low-growth assets. At 5.00% §7520, a zeroed-out CLAT funded with a 60/40 portfolio earning 5–6% passes almost nothing to heirs. The math requires real outperformance. Always model worst-case scenarios before committing.
2. Ignoring annuity payment liquidity. If the trust holds illiquid assets, it can't easily make cash annuity payments to charity. An illiquid trust that misses charity payments faces severe tax penalties. Liquidity planning is not optional.
3. Selecting a qualified charity incorrectly. Charities receiving CLAT payments must qualify under IRC §170(c) — public charities, not all nonprofits. Directing payments to a private foundation the grantor controls can trigger IRC §4941 self-dealing rules. Use an independent public charity or a donor-advised fund held at a community foundation.
4. Confusing grantor and non-grantor tax treatment. A grantor CLAT seems attractive because of the upfront income tax deduction, but the grantor then pays income tax on all trust income for the trust's entire term — even income paid to charity. Model the after-tax economics carefully before choosing the grantor structure.
5. Skipping GST planning on the remainder. If the remainder passes to grandchildren or a dynasty trust, it may trigger generation-skipping transfer (GST) tax unless GST exemption is allocated at CLAT creation. Coordinate with your trust attorney on GST allocation, especially for long-term or dynasty-trust remainders.
