CLT Calculation Details

How a Charitable Lead Trust Works

A Charitable Lead Trust (CLT) distributes income to one or more charities for a set term. When the term ends, the remaining assets pass to the donor's heirs β€” often with significant estate and gift tax savings.

CLAT Gift Valuation Formula

PV of Charity Payments = Annual Payment Γ— [(1 βˆ’ (1 + Β§7520)^-term) / Β§7520]
Taxable Gift = Contribution βˆ’ PV of Charity Payments

For zeroed-out CLAT: Payout Rate = Β§7520 Rate (gift = $0)
Above-hurdle return β†’ tax-free wealth transfer to heirs
Zeroed-Out CLAT Example: $2M contribution, 15-year term, 5.2% Β§7520 rate
Required annuity for $0 gift = $2M Γ— [5.2% / (1 βˆ’ 1.052^-15)] = ~$196K/year
If trust earns 8%: Final remainder = ~$1.1M β†’ heirs receive $1.1M with $0 gift tax
If trust earns only 5.2%: Remainder = ~$0 (exactly zeroed out)

Strategy tip: CLATs perform best when the trust's actual return exceeds the Β§7520 rate. In a rising-rate environment, consider a shorter term CLAT to capture any rate decrease for the zeroed-out calculation. A trust funded in a 5.2% rate environment that earns 8% can transfer substantial wealth tax-free.

Frequently Asked Questions

What is a Charitable Lead Trust and how does it differ from a Charitable Remainder Trust?
A CLT is the reverse of a CRT. In a Charitable Remainder Trust, the donor receives income for life and charity gets the remainder at death. In a Charitable Lead Trust, charity receives income FIRST for a set term, then the remainder passes to the donor's heirs. CLTs are primarily estate and gift tax planning tools, while CRTs are primarily income tax tools.
What is a "zeroed-out" CLAT?
A zeroed-out CLAT is structured so the present value of the charitable annuity payments equals the entire contribution amount, making the taxable gift to heirs mathematically zero. The technique works when the trust's actual investment return exceeds the IRS Section 7520 rate. Any "above-hurdle" growth passes to heirs completely gift-tax-free.
What is the Section 7520 rate and how does it affect CLTs?
The IRS Section 7520 rate (approximately 5.2% in April 2026) is the assumed rate of return for valuing charitable interests. For CLTs, a lower 7520 rate means charity's income stream is valued higher, making it easier to zero out the gift. A higher rate means more gift passes to heirs. CLTs perform best in low-rate environments.
What is the difference between a CLAT and a CLUT?
A CLAT (Charitable Lead Annuity Trust) pays a fixed dollar annuity to charity each year. A CLUT (Charitable Lead Unitrust) pays a fixed percentage of the trust's annually revalued assets to charity. CLATs are more commonly used for zeroed-out planning because the fixed payment is easy to calculate. CLUTs offer inflation protection but make zeroing out more complex.
Does a CLT provide an income tax deduction?
For a grantor CLT (CLAT), the donor gets an immediate income tax deduction for the present value of all charitable payments when the trust is funded. However, the donor must also report the trust's income during the term. Non-grantor CLTs get no upfront income tax deduction but the trust pays tax. Gift CLATs (non-grantor) are primarily used for gift and estate tax savings, not income tax.
