DEPARTMENT OF REVENUE

(1) Introduction. This rule applies to deaths occurring on or after May 17, 2005, and describes the nature of Washington state's estate tax as it is imposed by chapter 83.100 RCW (Estate and Transfer Tax Act). It also defines terms that will be used throughout chapter 458-57 WAC (Washington Estate and Transfer Tax Reform Act rules). The estate tax rule on the nature of estate tax and definitions for deaths occurring on or before May 16, 2005, can be found in WAC 458-57-005.

(2) Nature of Washington's estate tax. The estate tax is neither a property tax nor an inheritance tax. It is a tax imposed on the transfer of the entire taxable estate and not upon any particular legacy, devise, or distributive share.

(a) Relationship of Washington's estate tax to the federal estate tax. The department administers the estate tax under the legislative enactment of chapter 83.100 RCW, which references the Internal Revenue Code (IRC) as it existed January 1, 2005. Federal estate tax law changes enacted after January 1, 2005, do not apply to the reporting requirements of Washington's estate tax. The department will follow federal Treasury Regulations section 20 (Estate tax regulations), in existence on January 1, 2005, to the extent they do not conflict with the provisions of chapter 83.100 RCW or 458-57 WAC. For deaths occurring January 1, 2009, and after, Washington has different estate tax reporting and filing requirements than the federal government. There will be estates that must file an estate tax return with the state of Washington, even though they are not required to file with the federal government. The Washington state estate and transfer tax return and the instructions for completing the return can be found on the department's web site at http://www.dor.wa.gov/ under the heading titled forms. ((The return and instructions can also be requested by calling the department's estate tax section at 360-570-3265, option 2.))

(b) Lifetime transfers. Washington estate tax taxes lifetime transfers only to the extent included in the federal gross estate. The state of Washington does not have a gift tax.

(D) The amount of any deduction allowed for the qualified family-owned business interest.

(1) Introduction. This rule applies to deaths occurring on or after May 17, 2005, and is intended to help taxpayers prepare their return and pay the correct amount of Washington state estate tax. It explains the necessary steps for determining the tax and ((provides examples of)) how the tax is calculated. The estate tax rule on valuation of property etc., for deaths occurring on or before May 16, 2005, can be found in WAC 458-57-015.

(2) Determining the property subject to Washington's estate tax.

(a) General valuation information. The value of every item of property in a decedent's gross estate is its date of death fair market value. However, the personal representative may elect to use the alternate valuation method under section 2032 of the Internal Revenue Code (((IRC))), and in that case the value is the fair market value at that date, including the adjustments prescribed in that section of the ((IRC)) Internal Revenue Code. The valuation of certain farm property and closely held business property, properly made for federal estate tax purposes pursuant to an election authorized by section 2032A of the Internal Revenue Code of 2005 ((IRC)), is binding on the estate for state estate tax purposes.

(b) How is the gross estate determined? The first step in determining the value of a decedent's Washington taxable estate is to determine the total value of the gross estate. The value of the gross estate includes the value of all the decedent's tangible and intangible property at the time of death. In addition, the gross estate may include property in which the decedent did not have an interest at the time of death. A decedent's gross estate for estate tax purposes may therefore be different from the same decedent's estate for local probate purposes. Sections 2031 through 2046 of the ((IRC)) Internal Revenue Code provide a detailed explanation of how to determine the value of the gross estate.

(c) Deductions from the gross estate. The value of the taxable estate is determined by subtracting the authorized exemption and deductions from the value of the gross estate. Under various conditions and limitations, deductions are allowable for expenses, indebtedness, taxes, losses, charitable transfers, and transfers to a surviving spouse. While sections 2051 through 2056A of the ((IRC)) Internal Revenue Code provide a detailed explanation of how to determine the value of the taxable estate the following areas are of special note:

(i) Funeral expenses.

(A) Washington is a community property state and under Estate of Julius C. Lang v. Commissioner, 97 Fed. 2d 867 (9th Cir. 1938) affirming the reasoning of Wittwer v. Pemberton, 188 Wash. 72, 76, 61 P.2d 993 (1936) funeral expenses reported for a married decedent must be halved. Administration expenses are not a community debt and are reported at 100%.

(B) Example. John, a married man, died in 2005 with an estate valued at $2.5 million. On Schedule J of the federal estate tax return listed following as expenses:

The funeral expenses, as a community debt, were properly reported at 50% and the other administration expenses were properly reported at 100%.

(ii) Mortgages and liens on real property. Real property listed on Schedule A should be reported at its fair market value without deduction of mortgages or liens on the property. Mortgages and liens are reported and deducted using Schedule K.

(iii) Washington qualified terminable interest property (QTIP) election.

(A) A personal representative may choose to make a larger or smaller percentage or fractional QTIP election on the Washington return than taken on the federal return in order to reduce Washington estate liability while making full use of the federal unified credit.

(B) Section 2056 (b)(7) of the ((IRC)) Internal Revenue Code states that a QTIP election is irrevocable once made. ((Section 2044 states that the value of any property for which a deduction was allowed under section 2056 (b)(7) must be included in the gross estate of the recipient. Similarly,)) For the taxpayer that makes this election, any amount deducted by reason of section 2056 (b)(7) of the Internal Revenue Code is added to, and the value of the property for which a Washington election is made is deducted from, the Washington taxable estate. For the estate of the surviving spouse, the amount included in the estate's gross estate pursuant to section 2044 (a) and (b)(1)(A) of the Internal Revenue Code is deducted from, and the value of any property for which an election under this section was previously made is added to, the Washington taxable estate. A QTIP election made on the Washington return is irrevocable, and a surviving spouse who is the lifetime beneficiary of property for which a Washington QTIP election was made must include the value of the remaining property in his or her gross estate for Washington estate tax purposes. If the value of property for which a federal QTIP election was made is different, this value is not includible in the surviving spouse's gross estate for Washington estate tax purposes; instead, the value of property for which a Washington QTIP election was made is includible.

(C) The Washington QTIP election must adequately identify the assets, by schedule and item number, included as part of the election, either on the return or, if those assets have not been determined when the estate tax return is filed, on a statement to that effect, prepared when the assets are definitively identified. Identification of the assets is necessary when reviewing the surviving spouse's return, if a return is required to be filed. This statement may be filed with the department at that time or when the surviving spouse's estate tax return is filed.

(iv) Washington qualified domestic trust (QDOT) election.

(A) A deduction is allowed for property passing to a surviving spouse who is not a U.S. citizen in a qualified domestic trust (a "QDOT"). An executor may elect to treat a trust as a QDOT on the Washington estate tax return even though no QDOT election is made with respect to the trust on the federal return; and also may forgo making an election on the Washington estate tax return to treat a trust as a QDOT even though a QDOT election is made with respect to the trust on the federal return. An election to treat a trust as a QDOT may not be made with respect to a specific portion of an entire trust that otherwise would qualify for the marital deduction, but if the trust is actually severed pursuant to authority granted in the governing instrument or under local law prior to the due date for the election, a QDOT election may be made for any one or more of the severed trusts.

(B) A QDOT election may be made on the Washington estate tax return with respect to property passing to the surviving spouse in a QDOT, and also with respect to property passing to the surviving spouse if the requirements of ((IRC)) section 2056 (d)(2)(B) of the Internal Revenue Code are satisfied. Unless specifically stated otherwise herein, all provisions of sections 2056(d) and 2056A of the ((IRC)) Internal Revenue Code, and the federal regulations promulgated thereunder, are applicable to a Washington QDOT election. Section 2056A(d) of the ((IRC)) Internal Revenue Code states that a QDOT election is irrevocable once made. Similarly, a QDOT election made on the Washington estate tax return is irrevocable. For purposes of this subsection, a QDOT means, with respect to any decedent, a trust described in ((IRC)) section 2056A(a) of the Internal Revenue Code, provided, however, that if an election is made to treat a trust as a QDOT on the Washington estate tax return but no QDOT election is made with respect to the trust on the federal return:

(I) The trust must have at least one trustee that is an individual citizen of the United States resident in Washington state, or a corporation formed under the laws of the state of Washington, or a bank as defined in ((IRC)) section 581 of the Internal Revenue Code that is authorized to transact business in, and is transacting business in, the state of Washington (the trustee required under this subsection is referred to herein as the "Washington Trustee");

(II) The Washington Trustee must have the right to withhold from any distribution from the trust (other than a distribution of income) the Washington QDOT tax imposed on such distribution;

(III) The trust must be maintained and administered under the laws of the state of Washington; and

(IV) The trust must meet the additional requirements intended to ensure the collection of the Washington QDOT tax set forth in (c)(iv)(D) of this subsection.

(C) The QDOT election must adequately identify the assets, by schedule and item number, included as part of the election, either on the return, or, if those assets have not been determined when the estate tax return is filed, or a statement to that effect, prepared when the assets are definitively identified. This statement may be filed with the department at that time or when the first taxable event with respect to the trust is reported to the department.

(D) In order to qualify as a QDOT, the following requirements regarding collection of the Washington QDOT tax must be satisfied.

(I) If a QDOT election is made to treat a trust as a QDOT on both the federal and Washington estate tax returns, the Washington QDOT election will be valid so long as the trust satisfies the statutory requirements of Treas. Reg. Section 20.2056A-2(d).

(II) If an election is made to treat a trust as a QDOT only on the Washington estate tax return, the following rules apply:

If the fair market value of the trust assets exceeds (($2 million)) the applicable exclusion amount as of the date of the decedent's death, or, if applicable, the alternate valuation date, the trust must comply with Treas. Reg. Section 20.2056A-2 (d)(1)(i), except that: If the bank trustee alternative is used, the bank must be a bank that is authorized to transact business in, and is transacting business in, the state of Washington, or a bond or an irrevocable letter of credit meeting the requirements of Treas. Reg. Section 20.2056A-2 (d)(1)(i)(B) or (C) must be furnished to the department.

If the fair market value of the trust assets is (($2 million)) equal to the applicable exclusion amount or less as of the date of the decedent's death, or, if applicable, the alternate valuation date, the trust must comply with Treas. Reg. Section 20.2056A-2 (d)(1)(ii), except that not more than 35 percent of the fair market value of the trust may be comprised of real estate located outside of the state of Washington.

A taxpayer may request approval of an alternate plan or arrangement to assure the collection of the Washington QDOT tax. If such plan or arrangement is approved by the department, such plan or arrangement will be deemed to meet the requirements of this (c)(iv)(D).

(E) The Washington estate tax will be imposed on:

(I) Any distribution before the date of the death of the surviving spouse from a QDOT (except those distributions excepted by ((IRC)) section 2056A (b)(3) of the Internal Revenue Code); and

(II) The value of the property remaining in the QDOT on the date of the death of the surviving spouse (or the spouse's deemed date of death under IRC section 2056A (b)(4)). The tax is computed using Table W. The tax is due on the date specified in IRC section 2056A (b)(5). The tax shall be reported to the department in a form containing the information that would be required to be included on federal Form 706-QDT with respect to the taxable event, and any other information requested by the department, and the computation of the Washington tax shall be made on a supplemental statement. If Form 706-QDT is required to be filed with the Internal Revenue Service with respect to a taxable event, a copy of such form shall be provided to the department. Neither the residence of the surviving spouse or other QDOT beneficiary nor the situs of the QDOT assets are relevant to the application of the Washington tax. In other words, if Washington state estate tax would have been imposed on property passing to a QDOT at the decedent's date of death but for the deduction allowed by this subsection (c)(iv)(E)(II), the Washington tax will apply to the QDOT at the time of a taxable event as set forth in this subsection (c)(iv)(E)(II) regardless of, for example, whether the distribution is made to a beneficiary who is not a resident of Washington, or whether the surviving spouse was a nonresident of Washington at the date of the surviving spouse's death.

(F) If the surviving spouse of the decedent becomes a citizen of the United States and complies with the requirements of section 2056A (b)(12) of the ((IRC)) Internal Revenue Code, then the Washington tax will not apply to: Any distribution before the date of the death of the surviving spouse from a QDOT; or the value of the property remaining in the QDOT on the date of the death of the surviving spouse (or the spouse's deemed date of death under ((IRC)) section 2056A (b)(4) of the Internal Revenue Code).

(d) Washington taxable estate. The estate tax is imposed on the "Washington taxable estate." The "Washington taxable estate" ((means the "federal taxable estate":

(vi) Less any amount included in the federal taxable estate pursuant to IRC § 2044 (inclusion of amounts for which a federal QTIP election was previously made) from a predeceased spouse that died on or after May 17, 2005)) is defined in WAC 458-57-105 (3)(t).

(e) Federal taxable estate. The "federal taxable estate" ((means the taxable estate as determined under chapter 11 of the IRC without regard to:

(ii) The deduction for state estate, inheritance, legacy, or succession taxes allowable under section 2058 of the IRC)) is defined in WAC 458-57-105 (3)(i).

(3) Calculation of Washington's estate tax.

(a) The tax is calculated by applying Table W to the Washington taxable estate. ((See (d) of this subsection for the definition of "Washington taxable estate."))

Table W

(b) ((Examples.

Although Washington estate tax is not due, the estate is still required to file a Washington estate tax return along with a photocopy of the filed and signed federal return and all supporting documentation.)) Each year the department will publish each calendar year's "applicable exclusion amount." The "applicable exclusion amount" is adjusted annually and is defined in WAC 458-57-105 (3)(b).

(1) Introduction. This rule applies to deaths occurring on or after May 17, 2005, and discusses how to apportion the estate tax when there is out-of-state property included in the gross estate. The estate tax rule on apportionment of estate tax for deaths occurring on or before May 16, 2005, can be found in WAC 458-57-025.

(2) Calculation of apportioned tax. Apportionment of the tax is allowed for estate property located outside of Washington, even if the other state where the out-of-state property is located does not impose an estate tax. The amount of tax is determined by multiplying the preapportioned tax using Table W (((see WAC 458-57-115) multiplied)) by a fraction. The numerator of the fraction is the value of the property included in the decedent's gross estate that is located in Washington. The denominator of the fraction is the value of the decedent's gross estate. Intangible property is located in Washington if the decedent was a resident of this state at death. Property qualifying for the farm deduction or the family-owned business interest deduction is excluded from the numerator and denominator of the fraction. See WAC 458-57-155 ((()), Farm deduction(())), for additional information ((on the farm deduction.

The estate does not have to pay estate tax to the state of Arizona in order to reduce the tax owed to Washington. The estate tax due to Washington is $90,323)).

(((4))) (a) Example – Washington resident decedent. A widow dies during 2014 leaving a gross estate of $4.1 million. The decedent was a Washington resident at death. Decedent's primary residence is located in Seattle, Washington. The decedent also owned a second home in Arizona valued at $300,000 and unimproved real property in South Dakota valued at $750,000. The estate had $100,000 in expenses deductible for federal estate tax purposes. The applicable exclusion amount for 2014 after adjustment for inflation is $2,012,000.

(3) When is property located in Washington? ((A decedent's estate may have either real property or tangible personal property located in Washington)) The location of property owned by the decedent is determined at the time of death.

(a) All real property physically situated in this state, with the exception of federal trust lands, and all interests in such property, ((are deemed ")) is located in((")) Washington. ((Such)) Interests in real property include, but are not limited to:

(i) ((Leasehold interests;

(ii))) Mineral interests;

(iv) Trusts ()) (ii) Decedent's beneficial interest in real property held in trust((s of realty))); and

(((v))) (iii) Decedent's interest in jointly owned property (e.g., tenants in common, joint with right of survivorship).

(b) Tangible personal property of a ((nonresident)) decedent ((shall be deemed)) is located in Washington ((only)) if:

(i) At the time of death the property is situated in Washington; and

(ii) It is present for a purpose other than transiting the state.

(c) Intangible personal property of a decedent is located in Washington if the decedent was a resident of this state at death.

(d) Example. A nonresident decedent was a construction contractor doing business as a sole proprietor. The decedent was constructing a large building in Washington. At the time of death, any of the decedent's equipment that was located at the job site ((in Washington)), such as tools, earthmovers, bulldozers, trucks, etc., ((would be deemed)) is located in Washington for estate tax purposes((. Also, the decedent had negotiated and signed a purchase contract for speculative property in another part of Washington. For estate tax purposes, that real property should also be considered a part of the decedent's estate located in Washington)) because that property was present in the state for a purpose other than transiting the state.

(1) Introduction. This rule applies to deaths occurring on or after January 1, 2014, and is intended to determine if the estate is eligible for the qualified family-owned business interest deduction and to correctly calculate the deduction.

(a) "Material participation" has the same meaning as provided in section 2032A(e)(6) of the Internal Revenue Code as amended or renumbered as of January 1, 2005. Under the federal tax provision, "material participation" generally means the individual is materially involved in making significant management decisions for the trade or business, but not necessarily the day-to-day operating decisions.

A decedent or a qualified heir will not be treated as materially participating in the family-owned business if:

(i) The income derived from carrying out the trade or business is from the management decisions of another individual or entity under an arrangement between the other individual or entity and the decedent or qualified heir.

(ii) The activities that constitute material participation of any agent of the decedent or qualified heir are not considered the activities of the decedent or qualified heir when determining their material participation in the family-owned business.

(iii) A trustee's activities managing a trust for the benefit of other individuals shall not be considered when determining whether any of the present interest beneficiaries of the trust materially participate in the family-owned business.

(b) "Member of the decedent's family" and "member of the family" have the same meaning as "member of the family" in RCW 83.100.046(10).

(c) "Qualified family-owned business interest" has the same meaning as provided in section 2057(e) of the Internal Revenue Code of 1986 as amended and renumbered as of December 31, 2003.

(d) "Qualified heir" has the same meaning as provided in section 2057(i) of the Internal Revenue Code of 1986 as amended and renumbered as of December 31, 2003.

(e) When a business is held in a trust, only the individuals with a present-beneficiary interest in the trust may qualify as a "qualified heir" or "member of decedent's family" under this rule.

(3) Criteria for claiming the deduction.

(a) For the purposes of determining the tax due under this chapter, a deduction is allowed for the value of the decedent's qualified family-owned business interests. The total deduction may not exceed two million five hundred thousand dollars.

(b) The deduction is available only if all the following criteria are met:

(i) The material participation requirements described in section 2032A(c)(6)(b)(ii) of the Internal Revenue Code are not met with respect to the qualified family-owned business interest which was acquired or passed from the decedent;

(ii) The qualified heir disposes of any portion of a qualified family-owned business interest, other than by a disposition to a member of the qualified heir's family or a person with an ownership interest in the qualified family-owned business or through a qualified conservation contribution under section 170(h) of the Internal Revenue Code;

(i) The additional estate tax liability under this subsection has been satisfied or has become unenforceable by reason of lapse of time; or

(ii) The department is satisfied that no further tax liability will arise under this subsection.

(g) Security acceptable to the department may be substituted for the lien imposed by (f) of this subsection.
