T dies in 2006. T's will establishes a testamentary trust (Trust) providing that income is to be paid to T's sister, S, for her life. On S's death, one-half of the corpus is to be paid to T's child, C (or to C's estate if C fails to survive S), and one-half of the corpus is to be paid to T's grandchild, GC (or to GC's estate if GC fails to survive S). On the Form 706, “United States Estate (and Generation-Skipping Transfer) Tax Return,” filed for T's estate, T's executor allocates all of T's available GST tax exemption to other transfers and trusts, such that Trust's inclusion ratio is 1. Subsequent to filing the Form 706 in 2007 and in accordance with applicable state law, the trustee divides Trust into two separate trusts, Trust 1 and Trust 2, with each trust receiving 50 percent of the value of the assets of the original trust as of the date of severance. Trust 1 provides that trust income is to be paid to S for life with remainder to C or C's estate, and Trust 2 provides that trust income is to be paid to S for life with remainder to GC or GC's estate. Because Trust 1 and Trust 2 provide for the same succession of interests in the aggregate as provided in the original trust, the severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied.
In 2006, T establishes Trust, an irrevocable trust providing that income may be paid from time to time in such amounts as the trustee deems advisable to any one or more members of the group consisting of T's children (A and B) and their respective descendants. In addition, the trustee may distribute corpus to any trust beneficiary in such amounts as the trustee deems advisable. On the death of the last to die of A and B, the trust is to terminate and the corpus is to be distributed in two equal shares, one share to the then-living descendants of each child, per stirpes. T elects, under section 2632(c)(5), to not have the automatic allocation rules contained in section 2632(c) apply with respect to T's transfers to Trust, and T does not otherwise allocate GST tax exemption with respect to Trust. As a result, Trust has an inclusion ratio of one. In 2008, the trustee of Trust, pursuant to applicable state law, divides Trust into two equal but separate trusts, Trust 1 and Trust 2, each of which has terms identical to the terms of Trust except for the identity of the beneficiaries. Trust 1 and Trust 2 each has an inclusion ratio of one. Trust 1 provides that income is to be paid in such amounts as the trustee deems advisable to A and A's descendants. In addition, the trustee may distribute corpus to any trust beneficiary in such amounts as the trustee deems advisable. On the death of A, Trust 1 is to terminate and the corpus is to be distributed to the then-living descendants of A, per stirpes, but, if A dies with no living descendants, the principal will be added to Trust 2. Trust 2 contains identical provisions, except that B and B's descendants are the trust beneficiaries and, if B dies with no living descendants, the principal will be added to Trust 1. Trust 1 and Trust 2 in the aggregate provide for the same beneficiaries and the same succession of interests as provided in Trust, and the severance does not shift any beneficial interest to a beneficiary who occupies a lower generation than the person or persons who held the beneficial interest in Trust. Accordingly, the severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied.
In 2004, T establishes Trust, an irrevocable trust providing that income is to be paid to T's child C during C's lifetime. Upon C's death, Trust is to terminate and the assets of Trust are to be paid to GC, C's child, if living, or, if GC is not then living, to GC's estate. T properly elects, under section 2632(c)(5), not to have the automatic allocation rules contained in section 2632(c) apply with respect to T's transfers to Trust, and T does not otherwise allocate GST tax exemption with respect to Trust. Thus, Trust has an inclusion ratio of one. In 2009, the trustee of Trust, pursuant to applicable state law, divides Trust into two separate trusts, Trust 1 for the benefit of C (and on C's death to C's estate), and Trust 2 for the benefit of GC (and on GC's death to GC's estate). The document severing Trust directs that Trust 1 is to be funded with an amount equal to the actuarial value of C's interest in Trust prior to the severance, determined under section 7520 of the Internal Revenue Code. Similarly, Trust 2 is to be funded with an amount equal to the actuarial value of GC's interest in Trust prior to the severance, determined under section 7520. Trust 1 and Trust 2 do not provide for the same succession of interests as provided under the terms of the original trust. Therefore, the severance is not a qualified severance. Furthermore, because the severance results in no non-skip person having an interest in Trust 2, Trust 2 constitutes a skip person under section 2613 and, therefore, the severance results in a taxable termination subject to GST tax.
On September 1, 2006, T transfers $100,000 to a trust for the benefit of T's grandchild, GC. On a timely filed Form 709, “United States Gift (and Generation-Skipping Transfer) Tax Return,” reporting the transfer, T allocates all of T's remaining GST tax exemption ($50,000) to the trust. As a result of the allocation, the applicable fraction with respect to the trust is .50 [$50,000 (the amount of GST tax exemption allocated to the trust) divided by $100,000 (the value of the property transferred to the trust)]. The inclusion ratio with respect to the trust is .50 [1−.50]. In 2007, pursuant to authority granted under applicable state law, the trustee severs the trust into two trusts, Trust 1 and Trust 2, each of which is identical to the original trust and each of which receives a 50 percent fractional share of the total value of the original trust, valued as of the date of severance. Because the applicable fraction with respect to the original trust is .50 and the trust is severed into two equal trusts, the trustee may designate which resulting trust has an inclusion ratio of one, and which resulting trust has an inclusion ratio of zero. Accordingly, in the Notice of Qualified Severance reporting the severance, the trustee designates Trust 1 as having an inclusion ratio of zero, and Trust 2 as having an inclusion ratio of one. The severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied.
T's will establishes a testamentary trust (Trust) for the benefit of T's descendants, to be funded with T's stock in Corporation A and Corporation B, both publicly traded stocks. T dies on May 1, 2004, at which time the Corporation A stock included in T's gross estate has a fair market value of $100,000 and the stock of Corporation B included in T's gross estate has a fair market value of $200,000. On a timely filed Form 706, T's executor allocates all of T's remaining GST tax exemption ($270,000) to Trust. As a result of the allocation, the applicable fraction with respect to Trust is .90 [$270,000 (the amount of GST tax exemption allocated to the trust) divided by $300,000 (the value of the property transferred to the trust)]. The inclusion ratio with respect to Trust is .10 [1−.90]. On August 1, 2008, in accordance with applicable local law, the trustee executes a document severing Trust into two trusts, Trust 1 and Trust 2, each of which is identical to Trust. The instrument designates August 3, 2008, as the date of severance (within the meaning of paragraph (d)(3) of this section). The terms of the instrument severing Trust provide that Trust 1 is to be funded on a non-pro rata basis with assets having a fair market value on the date of severance equal to 90% of the value of Trust's assets on that date, and Trust 2 is to be funded with assets having a fair market value on the date of severance equal to 10% of the value of Trust's assets on that date. On August 3, 2008, the value of the Trust assets totals $500,000, consisting of Corporation A stock worth $450,000 and Corporation B stock worth $50,000. On August 4, 2008, the trustee takes all action necessary to transfer all of the Corporation A stock to Trust 1 and to transfer all of the Corporation B stock to Trust 2. On August 6, 2008, the stock transfers are completed and the stock is received by the appropriate resulting trust. Accordingly, Trust 1 is funded with assets having a value equal to 90% of the value of Trust as of the date of severance, August 3, 2008, and Trust 2 is funded with assets having a value equal to 10% of the value of Trust as of the date of severance. Therefore, the severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied. Trust 1 will have an inclusion ratio of zero and Trust 2 will have an inclusion ratio of one.
(i) T's will establishes an irrevocable trust (Trust) for the benefit of T's descendants. As a result of the allocation of GST tax exemption, the applicable fraction with respect to Trust is .60 and Trust's inclusion ratio is .40 [1-.60]. Pursuant to authority granted under applicable state law, on August 1, 2008, the trustee executes a document severing Trust into two trusts, Trust 1 and Trust 2, each of which is identical to Trust. The instrument of severance provides that the severance is intended to qualify as a qualified severance within the meaning of section 2642(a)(3) and designates August 3, 2008, as the date of severance (within the meaning of paragraph (d)(3) of this section). The instrument further provides that Trust 1 and Trust 2 are to be funded on a non-pro rata basis with Trust 1 funded with assets having a fair market value on the date of severance equal to 40% of the value of Trust's assets on that date and Trust 2 funded with assets having a fair market value equal to 60% of the value of Trust's assets on that date. The fair market value of the assets used to fund each trust is to be determined in compliance with the requirements of paragraph (d)(4) of this section.
(ii) On August 3, 2008, the fair market value of the Trust assets totals $4,000,000, consisting of 52% of the outstanding common stock in Company, a closely-held corporation, valued at $3,000,000 and $1,000,000 in cash and marketable securities. Trustee proposes to divide the Company stock equally between Trust 1 and Trust 2, and thus transfer 26% of the Company stock to Trust 1 and 26% of the stock to Trust 2. In addition, the appropriate amount of cash and marketable securities will be distributed to each trust. In accordance with paragraph (d)(4) of this section, for funding purposes, the interest in the Company stock distributed to each trust is valued as a pro rata portion of the value of the 52% interest in Company held by Trust before severance, without taking into account, for example, any valuation discount that might otherwise apply in valuing the noncontrolling interest distributed to each resulting trust.
(iii) Accordingly, for funding purposes, each 26% interest in Company stock distributed to Trust 1 and Trust 2 is valued at $1,500,000 (.5 × $3,000,000). Therefore, Trust 1, which is to be funded with $1,600,000 (.40 × $4,000,000), receives $100,000 in cash and marketable securities valued as of August 3, 2008, in addition to the Company stock, and Trust 2, which is to be funded with $2,400,000 (.60 × $4,000,000), receives $900,000 in cash and marketable securities in addition to the Company stock. Therefore, the severance is a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied.
T dies on October 1, 2004. T's will establishes a testamentary trust (Trust) to be funded with $1,000,000. Trust income is to be paid to T's child, S, for S's life. The trustee may also distribute trust corpus from time to time, in equal or unequal shares, for the benefit of any one or more members of the group consisting of S and T's three grandchildren (GC1, GC2, and GC3). On S's death, Trust is to terminate and the assets are to be divided equally among GC1, GC2, and GC3 (or their respective then-living descendants, per stirpes). On a timely filed Form 706, T's executor allocates all of T's remaining GST tax exemption ($300,000) to Trust. As a result of the allocation, the applicable fraction with respect to the trust is .30 [$300,000 (the amount of GST tax exemption allocated to the trust) divided by $1,000,000 (the value of the property transferred to the trust)]. The inclusion ratio with respect to the trust is .70 [1−.30]. On June 1, 2007, the trustee determines that it is in the best interest of the beneficiaries to sever Trust to provide a separate trust for each of T's three grandchildren and their respective families. The trustee severs Trust into two trusts, Trust 1 and Trust 2, each with terms and beneficiaries identical to Trust and thus each providing that trust income is to be paid to S for life, trust principal may be distributed for the benefit of any or all members of the group consisting of S and T's grandchildren, and, on S's death, the trust is to terminate and the assets are to be divided equally among GC1, GC2, and GC3 (or their respective then-living descendants, per stirpes). The instrument severing Trust provides that Trust 1 is to receive 30% of Trust's assets and Trust 2 is to receive 70% of Trust's assets. Further, each such trust is to be funded with a pro rata portion of each asset held in Trust. The trustee then severs Trust 1 into three equal trusts, Trust GC1, Trust GC2, and Trust GC3. Each trust is named for a grandchild of T and provides that trust income is to be paid to S for life, trust principal may be distributed for the benefit of S and T's grandchild for whom the trust is named, and, on S's death, the trust is to terminate and the trust proceeds distributed to the respective grandchild for whom the trust is named. If that grandchild has predeceased the termination date, the trust proceeds are to be distributed to that grandchild's then-living descendants, per stirpes, or, if none, then equally to the other two trusts resulting from the severance of Trust 1. Each such resulting trust is to be funded with a pro rata portion of each Trust 1 asset. The trustee also severs Trust 2 in a similar manner, into Trust GC1(2), Trust GC2(2), and Trust GC3(2). The severance of Trust into Trust 1 and Trust 2, the severance of Trust 1 into Trust GC1, Trust GC2, Trust GC3, and the severance of Trust 2 into Trust GC1(2), Trust GC2(2) and Trust GC3(2), constitute qualified severances, provided that all other requirements of section 2642(a)(3) and this section are satisfied with respect to each severance. Trust GC1, Trust GC2, Trust GC3 will each have an inclusion ratio of zero and Trust GC1(2), Trust GC2(2), and Trust GC3(2) will each have an inclusion ratio of one.
In 2004, T establishes an inter vivos irrevocable trust (Trust) for a term of 10 years providing that Trust income is to be paid annually in equal shares to T's child C and T's grandchild GC (the child of another then-living child of T). If either C or GC dies prior to the expiration of the 10-year term, the deceased beneficiary's share of Trust's income is to be paid to that beneficiary's then-living descendants, per stirpes, for the balance of the trust term. At the expiration of the 10-year trust term, the corpus is to be distributed equally to C and GC; if either C or GC is not then living, then such decedent's share is to be distributed instead to such decedent's then-living descendants, per stirpes. T allocates T's GST tax exemption to Trust such that Trust's applicable fraction is .50 and Trust's inclusion ratio is .50 [1−.50]. In 2006, pursuant to applicable state law, the trustee severs the trust into two equal trusts, Trust 1 and Trust 2. The instrument severing Trust provides that Trust 1 is to receive 50% of the Trust assets, and Trust 2 is to receive 50% of Trust's assets. Both resulting trusts are identical to Trust, except that each has different beneficiaries: C and C's descendants are designated as the beneficiaries of Trust 1, and GC and GC's descendants are designated as the beneficiaries of Trust 2. The severance constitutes a qualified severance, provided all other requirements of section 2642(a)(3) and this section are satisfied. Because the applicable fraction with respect to Trust is .50 and Trust was severed into two equal trusts, the trustee may designate which resulting trust has an inclusion ratio of one, and which has an inclusion ratio of zero. Accordingly, in the Notice of Qualified Severance reporting the severance, the trustee designates Trust 1 as having an inclusion ratio of one, and Trust 2 as having an inclusion ratio of zero. Because Trust 2 is a skip person under section 2613, the severance of Trust resulting in the distribution of 50% of Trust's corpus to Trust 2 would constitute a taxable termination or distribution (as described in section 2612(a)) of that 50% of Trust for GST tax purposes, but for the rule that a qualified severance is deemed to precede a taxable termination that is caused by the qualified severance. Thus, no GST tax will be due with regard to the creation and funding of Trust 2 because the inclusion ratio of Trust 2 is zero.
(i) In 2004, T establishes an inter vivos irrevocable trust (Trust) providing that trust income is to be paid annually in equal shares to T's children, A and B, for 10 years. Trust provides that the trustee has discretion to make additional distributions of principal to A and B during the 10-year term without adjustments to their shares of income or the trust remainder. If either (or both) dies prior to the expiration of the 10-year term, the deceased child's share of trust income is to be paid to the child's then living descendants, per stirpes, for the balance of the trust term. At the expiration of the 10-year term, the corpus is to be distributed equally to A and B; if A and B (or either or them) is not then living, then such decedent's share is to be distributed instead to such decedent's then living descendants, per stirpes. T allocates GST tax exemption to Trust such that Trust's applicable fraction is .25 and its inclusion ratio is .75.
(ii) In 2006, pursuant to applicable state law, the trustee severs the trust into three trusts: Trust 1, Trust 2, and Trust 3. The instrument severing Trust provides that Trust 1 is to receive 50% of Trust's assets, Trust 2 is to receive 25% of Trust's assets, and Trust 3 is to receive 25% of Trust's assets. All three resulting trusts are identical to Trust, except that each has different beneficiaries: A and A's issue are designated as the beneficiaries of Trust 1, and B and B's issue are designated as the beneficiaries of Trust 2 and Trust 3. The severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied. Trust 1 will have an inclusion ratio of 1. Because both Trust 2 and Trust 3 have each received the fractional share of Trust's assets equal to Trust's applicable fraction of .25, trustee designates that Trust 2 will have an inclusion ratio of one and that Trust 3 will have an inclusion ratio of zero.
On August 8, 2006, T transfers $1,000,000 to Trust and timely allocates $400,000 of T's remaining GST tax exemption to Trust. As a result of the allocation, the applicable fraction with respect to Trust is .40 [$400,000 divided by $1,000,000] and Trust's inclusion ratio is .60 [1−.40]. Trust provides that all income of Trust will be paid annually to C, T's child, for life. On C's death, the corpus is to pass in accordance with C's exercise of a testamentary limited power to appoint the corpus of Trust to C's lineal descendants. However, Trust provides that if, at the time of C's death, Trust's inclusion ratio is greater than zero, then C may also appoint that fraction of the trust corpus equal to the inclusion ratio to the creditors of C's estate. On May 3, 2008, pursuant to authority granted under applicable state law, the trustee severs Trust into two trusts. Trust 1 is funded with 40% of Trust's assets, and Trust 2 is funded with 60% of Trust's assets in accordance with the requirements of this section. Both Trust 1 and Trust 2 provide that all income of Trust will be paid annually to C during C's life. On C's death, Trust 1 corpus is to pass in accordance with C's exercise of a testamentary limited power to appoint the corpus to C's lineal descendants. Trust 2 is to pass in accordance with C's exercise of a testamentary power to appoint the corpus of Trust to C's lineal descendants and to the creditors of C's estate. The severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied. No additional contribution or allocation of GST tax exemption is made to either Trust 1 or Trust 2 prior to C's death. Accordingly, the inclusion ratio with respect to Trust 1 is zero. The inclusion ratio with respect to Trust 2 is one until C's death, at which time C will become the transferor of Trust 2 for GST tax purposes. (Some or all of C's GST tax exemption may be allocated to Trust 2 upon C's death.)
Trust is an irrevocable trust that has both skip person and non-skip person beneficiaries. Trust holds two parcels of real estate, Property A and Property B, stock in Company X, a publicly traded company, and cash. On June 16, 2008, the local court with jurisdiction over Trust issues an order, pursuant to the trustee's petition authorized under state law, severing Trust into two resulting trusts of equal value, Trust 1 and Trust 2. The court order directs that Property A will be distributed to Trust 1 and Property B will be distributed to Trust 2, and that an appropriate amount of stock and cash will be distributed to each trust such that the total value of property distributed to each trust as of the date of severance will be equal. The court order does not mandate a particular date of funding. Trustee receives notice of the court order on June 24, and selects July 16, 2008, as the date of severance. On June 26, 2008, Trustee commences the process of transferring title to Property A and Property B to the appropriate resulting trust(s), which process is completed on July 8, 2008. Also on June 26, the Trustee hires a professional appraiser to value Property A and Property B as of the date of severance and receives the appraisal report on Friday, October 3, 2008. On Monday, October 6, 2008, Trustee commences the process of transferring to Trust 1 and Trust 2 the appropriate amount of Company X stock valued as of July 16, 2008, and that transfer (as well as the transfer of Trust's cash) is completed by October 9, 2008. Under the facts presented, the funding of Trust 1 and Trust 2 occurred within 90 days of the date of severance selected by the trustee, and within a reasonable time after the date of severance taking into account the nature of the assets involved and the need to obtain an appraisal. Accordingly, the date of severance for purposes of this section is July 16, 2008, the resulting trusts are to be funded based on the value of the original trust assets as of that date, and the severance is a qualified severance assuming that all other requirements of section 2642(a)(3) and this section are met. (However, if Trust had contained only marketable securities and cash, then in order to satisfy the reasonable time requirement, the stock transfer would have to have been commenced, and generally completed, immediately after the date of severance, and the cash distribution would have to have been made at the same time.)
(i) In 2004, T establishes an irrevocable inter vivos trust (Trust) providing that Trust income is to be paid to T's children, A and B, in equal shares for their joint lives. Upon the death of the first to die of A and B, all Trust income will be paid to the survivor of A and B. At the death of the survivor, the corpus is to be distributed in equal shares to T's grandchildren, W and X (with any then-deceased grandchild's share being paid in accordance with that grandchild's testamentary general power of appointment). W is A's child and X is B's child. T elects under section 2632(c)(5) not to have the automatic allocation rules contained in section 2632(c) apply with respect to T's transfers to Trust, but T allocates GST tax exemption to Trust resulting in Trust having an inclusion ratio of .30.
(ii) In 2009, the trustee of Trust, as permitted by applicable state law, divides Trust into two separate trusts, Trust 1 and Trust 2. Trust 1 provides that trust income is to be paid to A for life and, on A's death, the remainder is to be distributed to W (or pursuant to W's testamentary general power of appointment). Trust 2 provides that trust income is to be paid to B for life and, on B's death, the remainder is to be distributed to X (or pursuant to X's testamentary general power of appointment). Because Trust 1 and Trust 2 do not provide A and B with the contingent survivor income interests that were provided to A and B under the terms of Trust, Trust 1 and Trust 2 do not provide for the same succession of interests in the aggregate as provided by Trust. Therefore, the severance does not satisfy the requirements of this section and is not a qualified severance. Provided that Trust 1 and Trust 2 are recognized as separate trusts under applicable state law, Trust 1 and Trust 2 will be recognized as separate trusts for GST tax purposes pursuant to paragraph (h) of this section, prospectively from the date of the severance. However, Trust 1 and Trust 2 each have an inclusion ratio of .30 immediately after the severance, the same as the inclusion ratio of Trust prior to severance.
Assume the same facts as in Example 12, except that, as of November 4, 2010, the trustee of Trust 1 severs Trust 1 into two trusts, Trust 3 and Trust 4, in accordance with applicable local law. The instrument severing Trust 1 provides that both resulting trusts have provisions identical to Trust 1. The terms of the instrument severing Trust 1 further provide that Trust 3 is to be funded on a pro rata basis with assets having a fair market value as of the date of severance equal to 70% of the value of Trust 1's assets on that date, and Trust 4 is to be funded with assets having a fair market value as of the date of severance equal to 30% of the value of Trust 1's assets on that date. The severance constitutes a qualified severance, provided that all other requirements of section 2642(a)(3) and this section are satisfied. Trust 3 will have an inclusion ratio of zero and Trust 4 will have an inclusion ratio of one.
