T transfers $200,000 to an irrevocable trust under which the income is payable to T's child, C, for life. Upon the termination of the trust, the remainder is payable to T's grandchild, GC. At a time when no ETIP exists with respect to the trust property, T makes a timely allocation of $100,000 of GST exemption, resulting in an inclusion ratio of .50. Subsequently, when the entire trust property is valued at $500,000, T allocates an additional $100,000 of T's unused GST exemption to the trust. The inclusion ratio of the trust is recomputed at that time. The numerator of the applicable fraction is $350,000 ($250,000 (the nontax portion as of the date of the allocation) plus $100,000 (the GST exemption currently being allocated)). The denominator is $500,000 (the date of allocation fair market value of the trust). The inclusion ratio is .30 (1 − .70).
On December 10, 1993, T transfers $10,000 to an irrevocable trust that does not satisfy the requirements of section 2642(c)(2). T makes identical transfers to the trust on December 10, 1994, 1995, 1996, and on January 15, 1997. Immediately after the transfer on January 15, 1997, the value of the trust principal is $40,000. On January 14, 1998, when the value of the trust principal is $50,000, T allocates $30,000 of GST exemption to the trust. T discloses the 1997 transfer on the Form 709 filed on January 14, 1998. Thus, T's allocation is a timely allocation with respect to the transfer in 1997, $10,000 of the allocation is effective as of the date of that transfer, and, on and after January 15, 1997, the inclusion ratio of the trust is .75 (1 − ($10,000/$40,000)). The balance of the allocation is a late allocation with respect to prior transfers to the trust and is effective as of January 14, 1998. In redetermining the inclusion ratio as of that date, the numerator of the redetermined applicable fraction is $32,500 ($12,500 (.25 × $50,000), the nontax portion of the trust on January 14, 1998) plus $20,000 (the amount of GST exemption allocated late to the trust). The denominator of the new applicable fraction is $50,000 (the value of the trust principal at the time of the late allocation).
(i) T creates an irrevocable trust for the benefit of T's child and grandchild in 1996 transferring $50,000 to the trust on the date of creation. T allocates no GST exemption to the trust on the Form 709 reporting the transfer. On July 1, 1997 (when the value of the trust property is $60,000), T transfers an additional $40,000 to the trust.
(ii) On April 15, 1998, when the value of the trust is $150,000, T files a Form 709 reporting the 1997 transfer and allocating $150,000 of GST exemption to the trust. The allocation is a timely allocation of $40,000 with respect to the 1997 transfer and is effective as of that date. Thus, the applicable fraction for the trust as of July 1, 1997 is .40 ($40,000/$100,000 ($40,000 + $60,000)).
(iii) The allocation is also a late allocation of $90,000, the amount necessary to attain a zero inclusion ratio on April 15, 1998, computed as follows: $60,000 (the nontax portion immediately prior to the allocation (.40 × $150,000)) plus $90,000 (the additional allocation necessary to produce a zero inclusion ratio based on a denominator of $150,000)/$150,000 equals one and, thus, an inclusion ratio of zero. The balance of the allocation, $20,000 ($150,000 less the timely allocation of $40,000 less the late allocation of $90,000) is void.
(i) The facts are the same as in Example 3, except that on February 1, 1998 (when the value of the trust is $150,000), T transfers an additional $50,000 to the trust and the value of the entire trust corpus on April 15, 1998 is $220,000. The Form 709 filed on April 15, 1998 does not disclose the 1998 transfer. Under the rule in § 26.2632-1(b)(2)(ii), the allocation is effective first as a timely allocation to the 1997 transfer; second, as a late allocation to the trust as of April 15, 1998; and, finally as a timely allocation to the February 1, 1998 transfer. As of April 15, 1998, $55,000, a pro rata portion of the trust assets, is considered to be the property transferred to the trust on February 1, 1998 (($50,000/$200,000) × $220,000). The balance of the trust, $165,000, represents prior transfers to the trust.
(ii) As in Example 3, the allocation is a timely allocation as to the 1997 transfer (and the applicable fraction as of July 1, 1997 is .40) and a late allocation as of 1998. The amount of the late allocation is $99,000, computed as follows: (.40 × $165,000 plus $99,000)/$165,000 = one.
(iii) The balance of the allocation, $11,000 ($150,000 less the timely allocation of $40,000 less the late allocation of $99,000) is a timely allocation as of February 1, 1998. The applicable fraction with respect to the trust, as of February 1, 1998, is .355, computed as follows: $60,000 (the nontax portion of the trust immediately prior to the February 1, 1998 transfer (.40 × $150,000)) plus $11,000 (the amount of the timely allocation to the 1998 transfer)/$200,000 (the value of the trust on February 1, 1998, after the transfer on that date) = $71,000/$200,000 = .355.
(iv) The applicable fraction with respect to the trust, as of April 15, 1998, is .805 computed as follows: $78,100 (the nontax portion immediately prior to the allocation (.355 × $220,000)) plus $99,000 (the amount of the late allocation)/ $220,000 = $177,100/$220,000 = .805.
(i) T transfers $100,000 to an irrevocable trust. The trust instrument provides that trust income is to be paid to T for 9 years or until T's prior death. The trust principal is to be paid to T's grandchild, GC, on the termination of T's income interest. The trustee has the power to invade trust principal for the benefit of GC during the term of T's income interest. The trust is subject to an ETIP while T holds the retained income interest. T files a timely Form 709 reporting the transfer and allocates $100,000 of GST exemption to the trust. In year 4, when the value of the trust is $200,000, the trustee distributes $15,000 to GC. The distribution is a taxable distribution. Because of the existence of the ETIP, the inclusion ratio with respect to the taxable distribution is determined immediately prior to the occurrence of the GST. Thus, the inclusion ratio applicable to the year 4 GST is .50 (1 − ($100,000/$200,000)).
(ii) In year 5, when the value of the trust is again $200,000, the trustee distributes another $15,000 to GC. Because the trust is still subject to the ETIP in year 5, the inclusion ratio with respect to the year 5 GST is again computed immediately prior to the GST. In computing the new inclusion ratio, the numerator of the applicable fraction is reduced by the nontax portion of prior GSTs occurring during the ETIP. Thus, the numerator of the applicable fraction with respect to the GST in year 5 is $92,500 ($100,000 − (.50 × $15,000)) and the inclusion ratio applicable with respect to the GST in year 5 is .537 (1 − ($92,500/$200,000) = .463). Any additional GST exemption allocated on a timely ETIP return with respect to the GST in year 5 is effective immediately prior to the transfer.
