A charitable lead annuity trust, or CLAT, can turn a family’s charitable commitment into an unusually efficient wealth-transfer strategy.
The strongest candidates for CLATs tend to be families who intend to make substantial charitable gifts regardless of the estate-planning benefit. The trust changes the timing and structure of those gifts while creating an opportunity to transfer future investment growth to children or other beneficiaries with potentially little use of the donor’s federal gift and estate tax exemption.
The strategy also comes with a measurable hurdle. Assets inside the trust must support the required charitable payments, and meaningful wealth-transfer benefits depend heavily on investment performance relative to the IRS interest rate used to value the transaction.
As of this writing in September 2026, the Section 7520 rate is 5.4%. Rates update monthly and the latest rates can be viewed here: IRS Section 7520 Interest Rates.
The evaluation of a CLAT as part of an estate planning strategy is complex, but is typically driven by three questions:
- Is a charitable commitment already part of the plan?
- Can the family comfortably part with the capital?
- Is there a credible investment case for leaving meaningful value to the next generation?
Key Takeaways
For the right family, a CLAT can connect philanthropy, investment management, and estate planning in a single strategy.
- Start with charitable intent. Families rarely create a CLAT simply to pursue a transfer-tax benefit. The family should already want to make the charitable gifts built into the trust.
- Focus on the spread. The economic opportunity comes from assets remaining after the charitable obligation has been met. Investment results above the Section 7520 hurdle can create substantial value for the family.
- Treat the CLAT as an investment strategy as well as an estate-planning strategy. Term length, liquidity, portfolio construction, required distributions, taxes, and sequence of returns can determine whether an attractive estate-planning concept produces an attractive result.
How a Charitable Lead Annuity Trust Works
A CLAT divides the economic benefit of a pool of assets between charity and family.
The donor irrevocably transfers assets to the trust. The trust then pays a specified annuity to one or more qualified charities for a predetermined period. When that period ends, the remaining assets pass to the noncharitable beneficiaries, in most cases children or trusts established for them.
The IRS values those two interests when the trust is created. Because charity has the right to receive the annuity payments first, the present value of that charitable interest reduces the value assigned to the remainder gift.
With careful structuring, the present value of the charitable annuity can approach the value originally transferred to the trust, leaving the actuarial value of the remainder gift near zero. This is commonly called a zeroed-out CLAT.
The structure effectively directs the scheduled payments to charity first, while the family receives whatever investment value remains after that obligation has been fulfilled. The investment assumptions therefore become central to the planning decision.
Families considering this type of irrevocable planning should view it alongside the rest of their estate planning and legacy strategy, rather than treating the trust as a standalone tax transaction.
The Role of the Section 7520 Rate
Section 7520 of the Internal Revenue Code provides the interest rate used to value certain annuities, remainder interests, and charitable interests.
The IRS calculates the rate using 120% of the applicable federal midterm rate, compounded annually and rounded as prescribed by the statute. Rates are updated monthly.
For CLAT planning, it’s helpful to think of this rate as an investment hurdle.
Consider a simplified hypothetical example. A family contributes $2 million to a 20-year CLAT. Using a 5.4% Section 7520 rate and assuming annual year-end payments, an annual charitable payment of approximately $166,000 has a present value of roughly $2 million.
Under those assumptions, the actuarial value assigned to the family remainder can be structured near zero. The charity would receive approximately $3.32 million in cumulative nominal payments over the 20-year term.
The important question is what remains for the family.
| Hypothetical Annual Return* | Approximate Remainder After 20 Years |
| 5.4% | $0 |
| 6.0% | $300,000 |
| 6.5% | $600,000 |
| 7.0% | $940,000 |
| 8.0% | $1.72 million |
*This is a simplified mathematical illustration, not a case study or investment projection. It assumes a constant annual return, approximately $166,000 of annual year-end charitable payments, and no taxes, fees, expenses, volatility, or other cash flows. Actual results will differ.
At a hypothetical 5.4% annual return, the trust essentially fulfills its charitable obligation and exhausts itself. At 7%, approximately $940,000 remains. At 8%, the remainder approaches $1.72 million.
Those dollars represent value that could ultimately reach the remainder beneficiaries after the trust has fulfilled its charitable commitment.
A CLAT becomes compelling when a family can make charitable gifts it already intends to make while creating a credible opportunity for investment growth above the valuation hurdle to accrue to the next generation.
A CLAT Is Also an Investment Portfolio with a Liability
The estate planning documents establish the structure, but the underlying asset portfolio within the trust determines much of the outcome.
A 20-year CLAT with a $166,000 annual annuity (like the one in our example above) effectively starts every year knowing that capital must leave the portfolio. The trustee therefore manages both an investment portfolio and a recurring liability.
Maximizing expected return without considering the distribution obligation would be poor portfolio construction. Holding an overly conservative portfolio creates a different problem because the assets may struggle to produce enough growth above the Section 7520 hurdle to leave a meaningful family remainder.
The sequence of returns also matters. If a CLAT suffers substantial investment losses early in its term, the charitable payment continues. Each payment then consumes a larger percentage of the remaining portfolio, leaving less capital available to participate in a subsequent recovery. Strong early returns create the opposite effect by leaving a larger pool of assets invested after each charitable distribution.
These liquidity management, diversification, return expectations, and downside risk considerations form a core component of the estate planning analysis. The same principle applies across a taxable portfolio: investment decisions should be evaluated by what they contribute to long-term, after-tax wealth. A disciplined approach to tax-efficient investing applies that perspective beyond the trust itself.
Higher Estate Tax Exemptions Raise the Bar for Using a CLAT
The federal transfer-tax environment changed materially in 2025 with the passage of the One Big Beautiful Bill.
For 2026, the federal basic exclusion amount is $15 million per individual. This higher exemption should make affluent families more selective about advanced estate-planning strategies.
For a married couple with substantial available exemptions, a CLAT should solve more than a theoretical estate-tax problem. As advisors, we would want to understand the family’s projected wealth decades from now, how much capital they expect to consume, what they intend to give to charity, what they want children to inherit, and how rapidly their assets could appreciate.
A family with $20 million today, for example, may have little immediate federal estate-tax exposure if both spouses have their full exclusions available. But decades of asset growth can change that picture substantially.
Planning projections matter because the relevant measure is the future estate, not simply today’s balance sheet. We also want the analysis to account for income and capital gains taxes, since reducing transfer taxes is only one measure of success.
Different gifting strategies can produce very different income-tax and estate-tax outcomes. Upstream gifting can create capital gains planning opportunities, while a CLAT is designed around a charitable lead interest followed by a family remainder. Neither strategy should be evaluated by one tax benefit in isolation.
Interest Rates Matter, But the Decision Shouldn’t Be Driven by Them
Lower Section 7520 rates are generally more favorable to the wealth-transfer economics of a CLAT because they reduce the hurdle that investment growth must clear.
Rates have moved meaningfully during the past two years. The IRS reports that the Section 7520 rate was 5.2% in January 2025, reached 5.4% in February and March, and fell to 4.6% for the final three months of 2025. During 2026, it began at 4.6%, reached 5.0% in May and June, 5.2% in July and August, and now 5.4% as of this writing in September 2026.
Pay attention to those changes without allowing the monthly rate to drive the strategy. A favorable rate cannot compensate for weak charitable intent, poor liquidity, an inappropriate asset, or unrealistic return assumptions. Conversely, a somewhat higher rate does not automatically rule out a CLAT for a family with a long horizon, strong charitable objectives, ample liquidity, and assets with attractive long-term growth potential.
Grantor and Nongrantor CLATs Require Different Tax Planning
CLATs can also be structured differently for income-tax purposes.
With a grantor CLAT, the donor may receive an upfront charitable income-tax deduction based on the present value of the qualifying charitable interest, subject to applicable rules and limitations. The grantor then generally reports the trust’s taxable income during the charitable term.
A nongrantor CLAT generally operates as a separate taxpayer and can claim qualifying charitable deductions under the trust income-tax rules.
The distinction affects current deductions, future taxable income, cash flow, and the assets we would consider placing inside the trust.
For a family evaluating a CLAT, it’s worth modeling both the transfer-tax result and the income-tax result. A strategy that looks excellent on an estate-tax diagram can become considerably less attractive once years of income taxation, investment turnover, charitable distributions, and outside cash-flow requirements are incorporated.
Charitable planning also intersects with portfolio planning. Families making significant philanthropic gifts often have several ways to fund them, including outright gifts, appreciated securities, donor-advised funds, and charitable trusts. The right structure depends in part on whether the primary objective is flexible charitable giving or a combination of philanthropy and multigenerational wealth transfer.
A donor-advised fund (DAF) can provide substantial flexibility in charitable and tax planning. A family can make an irrevocable charitable contribution, potentially receive a current charitable deduction subject to applicable rules, and recommend grants to charities over time. For a family primarily trying to organize its giving, bunch charitable deductions, contribute appreciated assets, or preserve flexibility over which charities ultimately receive grants, we would generally start with a DAF.
A CLAT asks more of the family. It commits the assets to a prescribed charitable payment stream and introduces investment, trust-administration, and wealth-transfer considerations. We would accept that additional complexity when transferring future growth to heirs is an important part of the objective and the economics justify it. In that setting, the CLAT is doing a job the DAF was never designed to do.
What Can Cause a CLAT to Fail Economically?
The legal structure can work exactly as intended while the financial result disappoints.
A CLAT that fulfills every charitable payment but leaves little or nothing for the family has accomplished its philanthropic purpose. It has not produced the wealth-transfer result the family expected.
Issues typically stem from four common failure points:
- The return assumption is doing too much work. If the strategy requires unusually strong returns to create an attractive remainder, the plan is fragile.
- Early losses consume the capital base. Required charitable payments continue during weak markets, potentially leaving less capital available for recovery.
- The contributed asset creates a liquidity mismatch. Illiquid or concentrated assets can create problems when the trust has fixed annual cash obligations.
- The family commits too much capital. A strategy can be tax-efficient and still be financially uncomfortable if circumstances change and the family needs assets it irrevocably transferred.
These are financial planning problems as much as estate planning problems. A smaller CLAT with more resilient economics may be a better option than maximizing the initial contribution simply because the tax rules permit it.
A CLAT Should Earn Its Place in the Plan
A charitable lead annuity trust can be one of the more elegant strategies available to a wealthy family with substantial philanthropic goals, but the bar for using one should be high.
A well-designed CLAT should improve the way the family funds charitable giving while creating a credible opportunity to transfer additional growth to the next generation. The charity receives a meaningful and predictable stream of support, while investment growth above the valuation hurdle can accrue to the remainder beneficiaries. The strategy has a clear job to do, and its success can be measured against that objective.
The planning does not stop with the trust itself. Committing assets to a CLAT changes the composition of the family’s broader balance sheet, which can make tax management and portfolio design elsewhere even more important. For some high-net-worth families, tax-aware long-short investing can be one way to manage taxable assets outside the trust with greater attention to after-tax outcomes. The two strategies serve different purposes, but both benefit from being coordinated within the same financial plan.
