Wash. Admin. Code § 458-57-125
(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 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 is excluded from the numerator and denominator of the fraction. See WAC 458-57-155, Farm deduction, for additional information.
(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.
Under the facts of this example the estate owes Washington estate tax on a Washington taxable estate of $1,988,000, computed as shown below:
| Gross estate: | $4,100,000 |
| Less allowable deductions: | ($100,000) |
| Less applicable exclusion amount: | ($2,012,000) |
| Washington taxable estate: | $1,988,000 |
The preapportionment Washington estate tax for this estate, using the table provided in WAC 458-57-115 (3)(a), equals $238,320, computed as follows: $100,000 + ($988,000 x 14%) = $238,320.
Because the decedent owned out-of-state property, a house in Arizona and unimproved real property in South Dakota that are not subject to Washington estate tax, the tax due to Washington is calculated by multiplying the amount of preapportionment tax computed above by the fraction described in this subsection (2). Also, because the decedent was a Washington resident at death, the numerator of the fraction is the value of all property included in the decedent's gross estate that is located in this state, including the decedent's intangible personal property. The denominator of the fraction is the value of the decedent's gross estate. Using the facts in our example, the tax owed to Washington equals $177,287, computed as follows: (($4,100,000 - $1,050,000)/$4,100,000) x $238,320 = $177,287.
(b) Example – Nonresident decedent. A widow dies during 2013 leaving a gross estate of $6 million. The decedent was a Colorado resident at death and all of the decedent's property is located in that state, except for a vacation home located in Washington valued at $650,000. The estate had $100,000 in expenses deductible for federal estate tax purposes. The applicable exclusion amount for 2013 is $2,000,000.
Under the facts of this example, the estate owes Washington estate tax on a Washington taxable estate of $3,900,000, computed as shown below:
| Gross estate: | $6,000,000 |
| Less allowable deductions: | ($100,000) |
| Less applicable exclusion amount: | ($2,000,000) |
| Washington taxable estate: | $3,900,000 |
The preapportionment Washington estate tax for this estate, using the table provided in WAC 458-57-115 (3)(a), equals $534,000, computed as follows: $390,000 + ($900,000 x 16%) = $534,000.
Because the decedent owned property located outside Washington, the tax due to Washington is calculated by multiplying the amount of preapportionment tax computed above by the fraction described in this subsection (2). Also, because the decedent was not a Washington resident at death, the numerator of the fraction does not include the value of decedent's intangible personal property. The denominator of the fraction is the value of the decedent's gross estate. Using the facts in this example, the tax owed to Washington equals $57,850, computed as follows: ($650,000/$6,000,000) x $534,000 = $57,850.
(3) When is 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, is located in Washington. Interests in real property include, but are not limited to:
(b) Tangible personal property of a decedent is located in Washington if:
