Charitable Lead Trusts: Give Now, Pass the Rest to Heirs

A CLT pays a charity first for a term of years, then returns the remainder to your family — often with a large up-front deduction.

The mirror image of a CRT

A charitable lead trust (CLT) is the reverse of a charitable remainder trust. Instead of paying you first and leaving the remainder to charity, a CLT pays a charity first — for a term of years — and then passes whatever remains to your heirs. The Charitable Lead Trust Calculator models all three pieces: the charity's payments, your deduction, and the remainder to family.

It appeals to people who are charitably inclined and want to pass assets to heirs at a reduced transfer-tax cost.

The up-front charitable deduction

In a 'grantor' CLT, you can claim an immediate income-tax deduction equal to the present value of all the future payments the charity will receive. With a large payout rate and long term, that deduction can be substantial — useful in a high-income year, such as one with a large bonus or asset sale.

The trade-off is that you remain taxable on the trust's income during the term. The calculator's deduction figure illustrates this present-value benefit.

Squeezing the remainder to heirs

In a 'non-grantor' CLAT used for estate planning, the goal is the remainder. You make a gift to the trust valued at the contribution minus the charity's lead interest — which can drive the taxable gift to nearly zero. If the trust then out-earns the §7520 hurdle, the excess passes to heirs free of additional transfer tax, much like a GRAT.

This makes CLATs powerful in low-interest-rate environments, when the hurdle is easy to beat and the charitable interest absorbs most of the gift value.

Choosing the structure

The two big design choices are grantor vs. non-grantor (income-tax deduction now vs. estate-planning transfer) and annuity vs. unitrust (fixed payments vs. a percentage of value). Each combination serves a different goal, so the right structure depends on whether you are chasing an income-tax deduction or an efficient transfer to heirs.

Because these levers interact with your income, your estate, and current interest rates, this is a decision to make with an advisor rather than off a template.

Who it suits

CLTs fit donors with genuine charitable intent, assets they don't need back for the trust term, and either a high-income year to offset or an estate-tax problem to solve. They are irrevocable and the charity genuinely receives the lead payments, so they are not a way to get money for nothing.

Set one up with an estate attorney and a charitable-giving advisor, and custody the assets where they can be managed prudently over the term — institutions like Vanguard and Fidelity offer the trust-investment services for exactly this.
