Quick overview
A Charitable Lead Annuity Trust (CLAT) sends a fixed dollar or percentage annuity to a charity for a set number of years. At trust termination the remaining assets go to named noncharitable beneficiaries (for example, children). CLATs are tools for combining meaningful philanthropy with wealth transfer planning; the tax and financial outcomes depend on the annuity design, the assets used to fund the trust, future investment performance, and current IRS valuation rules (including the Section 7520 rate).
Background and when CLATs are most useful
Charitable lead trusts date back many decades as part of U.S. philanthropic and estate planning practice. A CLAT — the ‘‘lead annuity’’ form — pays a fixed, predictable stream to charity (unlike a charitable lead unitrust, which pays a variable percentage of trust assets each year). CLATs typically make sense when:
- You want to provide reliable, multi-year support to a charity.
- You expect the assets funding the trust to appreciate materially (so heirs receive growth beyond the fixed annuity).
- You seek estate or gift tax advantages by shifting future appreciation out of your taxable estate.
- You can irrevocably give up the funded assets for the CLAT term and don’t need ongoing control.
In my practice, CLATs often suit business owners or investors who fund the trust with rapidly appreciating assets (for example, pre-sale equity or concentrated stock positions). The combination of a fixed charitable payout and potential asset growth can move value to heirs at lower transfer-tax cost.
(For a comparison to the variable-payout version, see our guide on “Charitable Remainder Trust” and the broader entry on “Charitable Lead Trust”.)

How a CLAT works — mechanics and tax basics
- Establish the trust. You create an irrevocable CLAT and name the charitable beneficiary(ies), the noncharitable remainder beneficiaries, the annuity amount (either a fixed dollar figure or a percentage of initial trust value), and the term (a set number of years or for life).
- Fund the trust. You transfer assets into the CLAT (cash, publicly traded securities, privately held stock, or other property). Because the trust is irrevocable, the transfer is generally treated as a completed gift for gift-tax and estate-tax purposes.
- Charity receives the annuity. The trust pays the fixed annuity to the named charity each year during the term.
- Remainder goes to heirs. At the end of the term the remaining trust corpus passes to the noncharitable beneficiaries.
Tax considerations to watch:
-
Charitable deduction/value: If the grantor creates a non-grantor CLAT, the donor may obtain a charitable gift deduction for gift-tax purposes equal to the present value of the annuity interest that will go to charity. That present value is calculated using the IRS Section 7520 rate in effect for the month of funding — a key determinant of tax outcomes (see IRS guidance on Section 7520). (IRS: Section 7520 and valuation rules: https://www.irs.gov)
-
Grantor vs non-grantor CLATs: If the donor structures the CLAT as a grantor trust (common for some planning goals), income tax is paid by the donor during the trust term and no income tax deduction is claimed. A non-grantor CLAT may generate a charitable deduction for gift/estate-tax calculation but the trust itself pays income tax on non-charitable amounts.
-
Estate and gift tax effects: By making an irrevocable gift of the remainder interest (or by designing the annuity so the charitable interest has value), you can reduce the grantor’s taxable estate. This is especially relevant for those with estate values above the applicable exclusion amount — which is adjusted annually by the IRS; always confirm the current exclusion on IRS.gov.

Example scenarios (practical illustrations)
-
Appreciating asset funded CLAT: A donor funds a CLAT with pre-IPO stock expected to appreciate. The CLAT pays a fixed annuity to a university for 15 years; if the stock grows faster than the fixed payments, the remainder passing to heirs can be substantial while the transfer-tax value recognized at funding may be smaller.
-
Cash-funded conservative CLAT: A donor with cash and a low-risk portfolio might fund a CLAT to support a charity for a fixed term, but if investments underperform relative to the fixed annuity the remainder for heirs could shrink or be exhausted — an important risk to consider.
Real-world takeaway: CLATs reward donors who fund the trust with high-growth assets and accept the irrevocable nature of the gift. I’ve seen successful outcomes when clients used concentration risk (a block of employer stock) to fund a CLAT before a liquidity event.
Who should consider a CLAT?
- High-net-worth individuals seeking to shift future appreciation to heirs while providing current support to charity.
- Business owners anticipating a liquidity event (sale, IPO) who can transfer pre-sale interests into a CLAT.
- Donors who want steady, guaranteed charitable payouts rather than variable percentages.
Not a fit when:
- You need flexible control or the ability to change beneficiaries.
- The assets you plan to fund are unlikely to outperform the fixed annuity.
- Your primary goal is immediate income tax deductions on individual income tax returns (CLAT deductions are primarily gift/estate-focused and depend on trust type).
Common mistakes and how to avoid them
- Picking the wrong payout form: confusing CLATs with unitrusts. Choose CLATs when you want predictability; choose a charitable lead unitrust (CLT) when you want payments tied to annual asset value.
- Misjudging investment performance: a fixed annuity can outpace asset growth, leaving little or no remainder for heirs. Stress-test scenarios before funding.
- Ignoring the Section 7520 rate: a higher 7520 rate reduces the present value of the charitable interest and can materially change gift-tax consequences.
- Using illiquid or restricted assets without an exit plan. If the trust must sell assets to make annuity payments, tax or transaction costs can erode benefits.
Steps to set up a CLAT (practical checklist)
- Clarify goals: philanthropic priorities, intended heirs, and tax objectives.
- Run valuation and rate scenarios: model the effect of different Section 7520 rates, annuity sizes, and investment returns.
- Choose assets to fund the trust: prioritize growth potential and liquidity planning.
- Draft trust documents with estate/charitable and tax counsel: include distribution mechanics and contingencies.
- Coordinate with CPA on gift-tax filing and ongoing reporting (Form 709 for gift tax reporting may be required; split-interest trust reporting can require Forms 5227 or similar depending on structure).
- Fund the trust and monitor performance; maintain communication with charity and trustees.
Alternatives and related tools
- Charitable Lead Unitrust (CLUT): pays a variable percent of trust value (useful when you expect periodic volatility).
- Charitable Remainder Trust: pays income to noncharitable beneficiaries first and leaves remainder to charity (the reverse flow of benefits).
- Donor-advised funds or direct gifts for simpler charitable support with less complexity.

Reporting, compliance, and trustee duties
CLATs have legal and tax compliance obligations. Trustees must make timely annuity payments, file required trust income tax returns if the trust is a non-grantor trust, and ensure charitable beneficiaries are recognized 501(c)(3) organizations. Depending on structure, split-interest trust informational returns (e.g., Form 5227) can apply — coordinate with your tax advisor and trustee to maintain compliance. (See IRS guidance on split-interest trusts and charitable trusts: https://www.irs.gov)
Practical tips from a planner’s perspective
- Model conservatively. Use stress scenarios that assume lower-than-expected growth and higher payout obligations.
- Use a CLAT only as part of a documented, multi-disciplinary plan — coordinate estate counsel, tax advisors, and investment managers.
- Consider trustee selection carefully; a corporate trustee may be preferable where complex asset management is needed.
Frequently asked questions
- Can I change the charity later? No. CLATs are irrevocable; changing charitable beneficiaries generally is not allowed unless the trust document includes a limited power of appointment or other specific provisions.
- Does a CLAT reduce my income taxes today? Not necessarily; the primary tax effects are on gift and estate taxation and on how future appreciation is allocated. Income-tax treatment depends on grantor vs non-grantor status.
- What affects the gift-tax value? The IRS Section 7520 rate and the chosen annuity amount are central — both affect the present value calculation used for tax reporting.
Conclusion and next steps
A CLAT can be a powerful solution for donors who want to guarantee charitable funding now while shifting expected future appreciation to heirs with potential estate or gift tax savings. However, outcomes depend on careful drafting, realistic investment assumptions, and attention to valuation rules. If you’re considering a CLAT, work with estate counsel and a tax advisor to run scenarios and draft trust language tailored to your goals.
