26 C.F.R. § 20.2010-2
Example 1. (i) Facts. The assets includible in H's gross estate consist of a parcel of real property and bank accounts held jointly with W with rights of survivorship, a life insurance policy payable to W, and a survivor annuity payable to W for her life. H made no taxable gifts during his lifetime.
(ii) Application. E files an estate tax return on which these assets are identified on the proper schedule, but E provides no information on the return with regard to the date of death value of these assets in accordance with paragraph (a)(7)(ii)(A) of this section. To establish the estate's entitlement to the marital deduction in accordance with § 20.2056(a)-1(b) (except with regard to establishing the value of the property) and the instructions for the estate tax return, E includes with the estate tax return evidence to verify the title of each jointly held asset, to confirm that W is the sole beneficiary of both the life insurance policy and the survivor annuity, and to verify that the annuity is exclusively for W's life. Finally, E reports on the estate return E's best estimate, determined by exercising due diligence, of the fair market value of the gross estate in accordance with paragraph (a)(7)(ii)(B) of this section. The estate tax return is considered complete and properly prepared and E has elected portability.
Example 2. (i) Facts. H's will, duly admitted to probate and not subject to any proceeding to challenge its validity, provides that H's entire estate is to be distributed outright to W. The non-probate assets includible in H's gross estate consist of a life insurance policy payable to H's children from a prior marriage, and H's individual retirement account (IRA) payable to W. H made no taxable gifts during his lifetime.
(ii) Application. E files an estate tax return on which all of the assets includible in the gross estate are identified on the proper schedule. In the case of the probate assets and the IRA, no information is provided with regard to date of death value in accordance with paragraph (a)(7)(ii)(A) of this section. However, E attaches a copy of H's will and describes each such asset and its ownership to establish the estate's entitlement to the marital deduction in accordance with the instructions for the estate tax return and § 20.2056(a)-1(b) (except with regard to establishing the value of the property). In the case of the life insurance policy payable to H's children, all of the regular return requirements, including reporting and establishing the fair market value of such asset, apply. Finally, E reports on the estate return E's best estimate, determined by exercising due diligence, of the fair market value of the gross estate in accordance with paragraph (a)(7)(ii)(B) of this section. The estate tax return is considered complete and properly prepared and E has elected portability.
Example 3. (i) Facts. H's will, duly admitted to probate and not subject to any proceeding to challenge its validity, provides that 50 percent of the property passing under the terms of H's will is to be paid to a marital trust for W and 50 percent is to be paid to a trust for W and their descendants.
(ii) Application. The amount passing to the non-marital trust cannot be verified without knowledge of the full value of the property passing under the will. Therefore, the value of the property of the marital trust relates to or affects the value passing to the trust for W and the descendants of H and W. Accordingly, the general return requirements apply to all of the property includible in the gross estate and the provisions of paragraph (a)(7)(ii) of this section do not apply.
Example 1. Computation of DSUE amount. (i) Facts. In 2002, having made no prior taxable gift, Husband (H) makes a taxable gift valued at $1,000,000 and reports the gift on a timely filed gift tax return. Because the amount of the gift is equal to the applicable exclusion amount for that year ($1,000,000), $345,800 is allowed as a credit against the tax, reducing the gift tax liability to zero. H dies in 2015, survived by Wife (W). H and W are U.S. citizens and neither has any prior marriage. H's taxable estate is $1,000,000. The executor of H's estate timely files H's estate tax return and elects portability, thereby allowing W to benefit from H's DSUE amount.
(ii) Application. The executor of H's estate computes H's DSUE amount to be $3,430,000 (the lesser of the $5,430,000 basic exclusion amount in 2015, or the excess of H's $5,430,000 applicable exclusion amount over the sum of the $1,000,000 taxable estate and the $1,000,000 amount of adjusted taxable gifts).
Example 2. Computation of DSUE amount when gift tax paid. (i) Facts. The facts are the same as in Example 1 of this paragraph (c)(5) except that the value of H's taxable gift in 2002 is $2,000,000. After application of the applicable credit amount, H owes gift tax on $1,000,000, the amount of the gift in excess of the applicable exclusion amount for that year. H pays the gift tax owed on the 2002 transfer.
(ii) Application. On H's death, the executor of H's estate computes the DSUE amount to be $3,430,000 (the lesser of the $5,430,000 basic exclusion amount in 2015, or the excess of H's $5,430,000 applicable exclusion amount over the sum of the $1,000,000 taxable estate and $1,000,000 of adjusted taxable gifts sheltered from tax by H's applicable credit amount). H's adjusted taxable gifts of $2,000,000 were reduced for purposes of this computation by $1,000,000, the amount of taxable gifts on which gift taxes were paid.
Example 3. Computation of DSUE amount when QDOT created. (i) Facts. Husband (H), a U.S. citizen, makes his first taxable gift in 2002, valued at $1,000,000, and reports the gift on a timely filed gift tax return. No gift tax is due because the applicable exclusion amount for that year ($1,000,000) equals the fair market value of the gift. H dies in 2015 with a gross estate of $2,000,000. H's surviving spouse (W) is a resident, but not a citizen, of the United States and, under H's will, a pecuniary bequest of $1,500,000 passes to a QDOT for the benefit of W. H's executor timely files an estate tax return and makes the QDOT election for the property passing to the QDOT, and H's estate is allowed a marital deduction of $1,500,000 under section 2056(d) for the value of that property. H's taxable estate is $500,000. On H's estate tax return, H's executor computes H's preliminary DSUE amount to be $3,930,000 (the lesser of the $5,430,000 basic exclusion amount in 2015, or the excess of H's $5,430,000 applicable exclusion amount over the sum of the $500,000 taxable estate and the $1,000,000 adjusted taxable gifts). No taxable events within the meaning of section 2056A occur during W's lifetime with respect to the QDOT, and W makes no taxable gifts. At all times since H's death, W has been a U.S. resident. In 2017, W dies and the value of the assets of the QDOT is $1,800,000.
(ii) Application. H's DSUE amount is redetermined to be $2,130,000 (the lesser of the $5,430,000 basic exclusion amount in 2015, or the excess of H's $5,430,000 applicable exclusion amount over $3,300,000 (the sum of the $500,000 taxable estate augmented by the $1,800,000 of QDOT assets and the $1,000,000 adjusted taxable gifts)).
Example 4. Computation of DSUE amount when surviving spouse with QDOT becomes a U.S. citizen. (i) Facts. The facts are the same as in Example 3 of this paragraph (c)(5) except that W becomes a U.S. citizen in 2016 and dies in 2018. The U.S. Trustee of the QDOT notifies the IRS that W has become a U.S. citizen by timely filing a final estate tax return (Form 706-QDT). Pursuant to section 2056A(b)(12), the estate tax under section 2056A no longer applies to the QDOT property.
(ii) Application. Because H's DSUE amount no longer is subject to adjustment once W becomes a citizen of the United States, H's DSUE amount is $3,930,000, as it was preliminarily determined as of H's death. Upon W's death in 2018, the value of the QDOT property is includible in W's gross estate.
