Annuity Lead Trust for Grandchildren
Generation-skipping transfer taxes (GSTTs) are particularly significant for charitable lead trusts. Since the goal of many grandparents is to allow grandchildren to grow to greater levels of maturity before receiving a significant inheritance, the opportunity to leverage an inheritance through a lead trust for grandchildren is quite attractive. It is possible to pass two to seven times the exemption amount to grandchildren with a testamentary lead trust and still have zero GSTTs.
Applicable Fraction for an Annuity Lead Trust
With an annuity lead trust, the applicable fraction is not calculated until the termination of the trust. The applicable fraction then equals the exemption with growth for the trust term calculated at the applicable federal rate as of trust inception, divided by the value of the trust at termination. Sec. 2642(e)(2). This method subjects the trust to considerable uncertainty. While it is possible to know the value of the exemption with projected growth, the actual trust corpus will not be known with certainty until the date of distribution. While it has been suggested that it could be possible to transfer to family the amount equal to the adjusted exemption and transfer the balance to charity at that time, there is no specific statute or ruling that approves of this concept.
The applicable fraction formula is (the allocated GSTT exemption times (1+AFR)^ selected term)/(trust corpus). This formula results in a zero inclusion if the exemption adjusted upward by the AFR growth rate for the selected number of years results in a number that exceeds the trust corpus. However, if the trust corpus grows significantly, payment of a very substantial generation-skipping transfer tax could be required. Since this is a taxable termination, the tax would be payable by the trustee at the rate applicable at the time of termination.
Unitrust Lead Trust for Grandchildren -- Applicable Fraction
In contrast to a lead annuity trust, a lead unitrust is permitted to calculate the applicable fraction as of the testator's date of death. This enables the trust to use a formula or other allocation method to zero the GSTT. With a unitrust lead trust, the applicable fraction equals the allocated exemption divided by the fair market value of the property minus the charitable deduction. If the allocated exemption is equal to the present value of the taxable gift, the applicable fraction equals one/one. Since the inclusion ratio equals one minus one, or zero, the lead unitrust is exempt from generation-skipping transfer tax.
Zero Inclusion Ratio
Because the value of the trust at the date of death may be determined, in estates in which the value of the taxable transfer is equal to or less than the exemption amount, it is quite common to use a testamentary charitable lead unitrust. The testamentary CLUT may be created and the funding or the payout adjusted so that the available exemption is fully utilized in a trust with a zero inclusion ratio and an exemption from generation-skipping transfer tax.
Multiple-Layer Lead Trusts for Children and Grandchildren
A strategy to minimize total taxation is to create a multi-layer lead trust. The first two layers could be charitable lead annuity trusts, with distributions to children. Thus, these layers would not be subject to generation-skipping transfer tax. However, layers three and four could be trusts for a longer duration with remainders to grandchildren or great-grandchildren. Through formula clauses or careful planning for trust funding levels, the charitable lead unitrusts for grandchildren would be designed to be exempt from generation-skipping transfer tax. It is even possible that the lead unitrust remainders could be distributed to a dynasty trust in a state without a rule against perpetuities.
