A charitable lead trust (CLT) is an irrevocable trust that pays income to one or more charities for a set period, then transfers the remaining assets to non-charitable beneficiaries such as family members. Think of it as a charitable first mortgage on a pool of assets: the charity gets paid first, and your heirs receive what is left over after the trust term ends.
CLTs are primarily used for estate and gift tax reduction. When structured correctly, they can dramatically reduce the taxable value of wealth passed to your heirs while generating substantial charitable contributions over the trust's lifetime.
You fund the trust by transferring assets, which can include cash, publicly traded stock, real estate, or private business interests. The trust then pays distributions to your designated charity on at least an annual basis. At the end of the trust term, which may be a fixed number of years or tied to the lifespan of one or more individuals, the remaining assets go to your chosen non-charitable beneficiaries.
The key tax advantage comes at the point of funding. The IRS calculates the present value of all projected charitable payments using the Section 7520 rate in effect for the month you create the trust. That present value becomes the gift or estate tax deduction.
CLTs use either an annuity payout or a unitrust payout. The choice affects both the stability of charitable payments and the potential growth of assets passing to heirs.
The tax treatment of a CLT depends on whether you structure it as a grantor trust or a non-grantor trust. The two structures serve different goals and produce opposite income tax outcomes.
| Grantor CLT | Non-Grantor CLT | |
|---|---|---|
| Income Tax Deduction | Yes, upfront deduction for present value of charitable payments | No income tax deduction for the donor |
| Who Pays Tax on Trust Income | The donor (treated as trust owner) | The trust pays tax as a complex trust |
| Best Use Case | Donor expecting a large one-time income event | Reducing gift and estate taxes; passing wealth to heirs |
| Deduction Limit | 30% of adjusted gross income (cash gifts to private foundations) | No income deduction applies |
| Charitable Deduction at Death | Available for estate tax purposes | Yes, estate qualifies for charitable deduction on lead interest |
A grantor CLT gives you an upfront income tax deduction equal to the present value of the total charitable payments the trust will make over its lifetime. For example, per IRS calculations, a $100,000 five-year CLAT with a 9% annuity payout rate generates an income tax deduction of approximately $41,217.
The catch is that you pay income tax annually on all income earned by the trust, including amounts paid to charity. This recapture mechanism makes grantor CLTs most useful in years when you have large, irregular income to offset, such as from an asset sale or a business liquidity event.
A non-grantor CLT does not give you an income tax deduction at setup. Instead, the trust pays its own income tax and deducts the charitable payments it makes each year. The estate and gift tax benefit is where the real value lies.
When you fund a non-grantor CLT during your lifetime, you may qualify for a gift tax charitable deduction based on the present value of the interest flowing to charity. Over the trust term, if assets grow faster than the Section 7520 rate used to value the charitable interest, more wealth passes to your heirs completely free of transfer tax.
The Section 7520 rate is the IRS discount rate used to value income interests in trusts. For CLATs, a lower Section 7520 rate increases the present value of the charitable lead interest, which lowers the taxable gift to heirs and may reduce or eliminate gift tax entirely. This is why CLATs historically performed well in low-interest-rate environments.
You can choose the Section 7520 rate from the month you create the trust or from either of the two preceding months, so you have some flexibility in maximizing the charitable deduction.
You can measure the CLT term by a fixed number of years or by the life of one or more individuals. Most CLTs use a fixed term. Under IRS rules, permissible measuring lives are limited to the donor, the donor's spouse, and individuals who are lineal ancestors or their spouses of all non-charitable remainder beneficiaries. There must also be less than a 15% probability that non-lineal descendants will receive any portion of the trust principal.
The trust must pay the charity at least annually. The IRS does not require a minimum payout percentage, unlike charitable remainder trusts. You could pay the charity as little as 1% or 2% of trust assets, though a higher payout increases the charitable deduction and reduces the taxable gift to heirs.
You can also name a donor-advised fund as the lead charitable beneficiary. This lets you maintain advisory privileges over how charitable distributions are granted to end recipients, adding flexibility to your giving strategy even after the trust is funded.
CLTs are irrevocable. Once you transfer assets to the trust, you cannot take them back. If investment performance is poor and trust income falls short of required charitable payments, the trustee must draw on capital gains or principal to make up the difference. In extreme scenarios, heirs could receive little or nothing at the end of the term.
CLTs are also not income-tax-exempt. Unlike a charitable remainder trust, a CLT pays income tax as a complex trust unless it is a grantor CLT. Setup costs and ongoing administrative fees add to the total cost. Work with a qualified estate planning attorney and a tax advisor before creating one.
