Estate tax FAQ

Does the state of Washington have an inheritance or estate tax?

Washington does not have an inheritance tax. Washington does have an estate tax.

During a general election in November 1981, the voters repealed an inheritance tax and enacted an estate tax. The change from an inheritance tax to an estate tax became effective January 1, 1982. Due to this change, Washington no longer has an inheritance tax waiver.

In general terms, an inheritance tax is a tax on the beneficiaries of an estate whereas an estate tax is a tax on the decedent’s estate.

If you are a person living in Washington who inherits property or money, you do not owe Washington taxes on your inheritance.

What is the estate tax?

The estate tax is a tax on the right to transfer property at the time of death. A person residing in Washington or a non-resident who owns property in Washington may owe an estate tax depending on the value of their estate.

Who must file a Washington estate tax return?

The executor for a decedent’s estate is required to file an estate tax return if the gross estate meets the filing threshold for the date of death. See the Filing Thresholds and Exclusion Amounts table to determine if an estate tax return is required to be filed.

If the total gross estate is below the filing threshold, no estate tax return needs to be filed. If the total gross estate is above the filing threshold, an estate tax return must be filed even if no tax would be due.

If a Washington return is required to be filed and a Federal Form 706 is filed, a copy of the Federal Form 706 must be included with the Washington estate tax filing.

What is the estate tax filing threshold?

The executor must file a Washington estate tax return if the decedent owned property in Washington state and the gross estate exceeds the filing threshold.

For estate tax filing amounts, see the Filing Thresholds and Exclusion Amounts.

What is the estate tax applicable exclusion amount?

The applicable exclusion amount is an amount deducted prior to calculating estate tax due. For dates of death of January 1, 2014, and after, the exclusion amount may be adjusted annually using the Seattle-Tacoma-Bremerton metropolitan area October consumer price index.

For applicable exclusion amounts, see the Filing Thresholds and Exclusion Amounts table.

What assets should be included in the estate? Is it different for a married couple?

All assets owned by the decedent on the date of death should be included in the estate. All assets, even if located in another state, should be reported on the estate tax return (see the Estate Tax Apportionment for Out of State Property page).

For the estate of a married decedent, all of the community property and all of the decedent’s separate property are reported on the estate tax return. The community property assets are then reduced by 50% to reflect the decedent’s share of the property. Even if the entire estate will pass to the surviving spouse and no taxes may be due, an estate tax return must be filed if the decedent’s half of the community property plus the decedent’s separate property meets the filing threshold.

Do I have to include out of state property on the estate tax return?

Yes. All property owned by a decedent must be included on the estate tax return. Once the estate tax is calculated on the entire estate, as if all property is in Washington, then a calculation is done to apportion the tax between the Washington property and the out of state property.

The decedent’s state of domicile at the time of death is what determines if property is in state or out of state property. For a Washington domiciled decedent any tangible personal property located outside of Washington and any real property located outside of Washington are considered out of state property. For an out of state domiciled decedent all intangible property, any tangible property located outside of Washington and any real property located outside of Washington are considered out of state property.

A decedent’s share of property or interest in a limited liability company (LLC), limited liability partnership (LLP), corporation, or other type of business entity, operating for a true business purpose, is considered an intangible asset and is allocated to the state of domicile. When one of these types of entities is used simply to hold property and does not operate for a true business purpose, then the location of the property is used to determine whether it is in state or out of state property.

For more details see the Estate Tax Apportionment for Out of State Property page.

How do I value the assets in the estate?

All assets owned by a decedent are valued at their actual value or fair market value for the valuation date.

The “actual value” of an asset is its cash value or unpaid principal plus any interest accrued to the valuation date.

The “fair market value” is the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the relevant facts. The fair market value would be a sale in an arm’s-length transaction and never determined by a forced sale. Fair market value for a business entity would include any goodwill inherent in the business. For most stocks and bonds the fair market value is the mean between the highest and lowest selling prices quoted on the valuation date.

The “valuation date” is the date of death of the decedent. However, an alternate value date (six months after the date of death) may be elected; see the instructions for the estate tax return to determine if alternate value may be elected for an estate.

When filing the estate tax return, be sure to include all supporting documentation showing the actual or fair market value. Supporting documentation can include, but is not limited to, real estate appraisals, date of death brokerage statements, and business appraisals.

How is the estate tax calculated?

The tax is calculated using the Washington taxable estate and Table W. The Washington taxable estate is the gross estate less all allowable deductions, including the applicable exclusion amount.

What are the estate tax rates for deaths on or after January 1, 2014?

The tax rates range from 10 percent to 20 percent of the Washington taxable estate. The taxes are calculated on a graduated scale; each range is taxed at a different rate. See Table W- Computation of Washington Estate Tax.

How do I know what the Washington taxable estate is?

To determine the Washington taxable estate, take the gross estate and subtract any allowable expenses and deductions. The allowable expenses and deductions include such items as the decedent's funeral expenses, costs of administering the estate, any debts of the decedent (mortgages, liens, outstanding bills), bequests to a spouse, gifts to charity, the farm deduction (if eligible), the qualified family-owned business interests deduction (if eligible) and the applicable exclusion amount.

What documentation should I include with the estate tax return?

Before sending the filing, please read the following:

• Estate tax filing instructions
• Estate tax filing checklist

What to Include When Filing - Assemble in Order Listed

• Payment, if any, made payable to Washington State Department of Revenue; 
• Original Washington State Estate and Transfer Tax Return signed by the executor; to include the first three pages of the form and any of the completed Washington return schedules;
• Addendum(s), if applicable;
• Copy of the filed Federal Form 706, if applicable; to include the first four pages of the form and any completed 706 return schedules;
• Copy of Death Certificate;
• Copy of Letters of Administration/Testamentary, if any;
• Copy of Will, if any;
• Copy of Trust(s), if any; and
• Copy of gift tax return(s) (Federal Form 709), if any; and
• All supporting documentation for the completed return schedules (one copy of each):
  • Appraisals,
  • Brokerage statements or valuation software reports,
  • Financial or bank statements,
  • Federal Form 712,
  • Business valuations, especially for closely-held or non-publicly traded businesses,
  • Any other type of document or calculation supporting the value reported on a schedule.

Note: All documentation must reflect the proper actual or fair market value of an asset as of the valuation date. For most estates the valuation date will be the date of death of the decedent. However, if alternate valuation is elected, then assets will have two valuation dates, the date of death and typically a date six months after the date of death (see Internal Revenue Code § 2032 for further clarification). When alternate valuation is reported two sets of supporting documentation must be sent; one showing date of death values and one showing values as of the alternate valuation date.

Or fax to (360) 534-1499.

What is the due date of the estate tax return?

The due date of the Washington State Estate and Transfer Tax Return is nine months after the date of death.

A timely filed extension application will automatically extend the return due date six months. Note: Any tax due must be paid within the nine months after the date of death or interest will accrue.

How do I file for an extension or an additional extension of the estate tax return?

When you are applying for your federal extension, send us a copy of the Federal Form 4768 at the time of filing, and include estimated Washington tax due, if any. If you are not filing a Federal Form 706, submit the Application for Extension of Time to File a Washington State Estate and Transfer Tax Return.

To request an additional extension in excess of the six month extension submit an Application for Extension of Time to File a Washington State Estate and Transfer Tax Return along with a statement explaining in detail why it is impossible or impractical to file by the due date. Be sure to mark the additional extension box and enter the date of the extension on the application form.

Note: The due date for either the Washington estate tax return and estate tax payment or a request for an extension to file the Washington estate tax return and an estimated payment is nine months after the decedent's date of death. Payment received after the due date will accrue interest.

What should I do if I previously filed an extension and now I know the estate is under the filing threshold?

Send us a short letter stating this fact. We will close our file.

How do I pay the estate tax, who do I make the check payable to and when is the payment due?

To pay the estate tax, send the payment with either a timely filed extension application or the Washington State Estate and Transfer Tax Return.

Mail the payment and form to:

Washington State Department of Revenue
PO Box 47488
Olympia WA 98504-7488

Make the check payable to: Washington State Department of Revenue.

The estate has nine months from the date of death to pay tax due. If the estate tax liability is unknown at the nine month due date an estimated tax payment should be made. An extension to file does not give an estate an extension to pay. Interest accrues on any unpaid tax outstanding after the nine month due date.

An estate that includes a qualifying closely-held business may be able to enter an installment payment plan for the portion of taxes attributable to the closely-held business.

Can I use the commercially available Federal Form 706 preparation software to complete the schedules for a Washington only filing of an estate tax return?

You may use the software to complete the schedules only. You must complete the first three pages of the Washington return and any applicable addendums.

What do we do if we are filing and/or paying late?

If an estate is not able to file a timely return, an Application for Extension of Time to File form (either the Washington form or a copy of the Federal Form 4768, if applicable) must be submitted prior to the due date of the estate tax return.

For any estate tax being paid late, late payment interest should be included with the payment. Interest accrues daily on any unpaid principal. The interest is calculated using simple interest, not compound interest. For assistance with computing interest on an estate tax return call the estate tax section at (360) 534-1503, select option 2.

What is the interest rate for estate tax?

The interest rate for estate tax changes annually. See our interest rate table for current rates. Interest accrues daily on any unpaid principal. The interest is calculated using simple interest, not compound interest. For assistance with computing interest on an estate tax return, call the estate tax section at (360) 534-1503, select option 2.

What is the late payment penalty or late filing penalty?

There is no late payment penalty. Interest will accrue on any late payment.

A late filing penalty will apply only if the Department notifies the executor in writing that we have determined a filing is required prior to the estate voluntarily notifying us a filing is required (e.g. written notification, filed extension, filed return). If a penalty is applied it is 5% of the tax due per month (up to 25% or $1,500, whichever is less).

How do I amend the estate tax return?

The Washington Estate and Transfer Tax Return has a checkbox on the form to designate the return as an amended return. To amend a previous filing, simply complete a new estate tax form with the amended return box checked. The first page, along with any other return, schedule, and/or addendum pages that have been changed, must be sent with all supporting documentation showing why the return is being amended. We do not need a complete filing of the original return, only the pages that have been changed and documentation explaining those changes.

Does Washington recognize portability of any unused exemption amount?

Washington law does not have, nor does it incorporate, the federal provisions of portability for estate tax. Each estate is entitled to the applicable exclusion amount based on the decedent’s date of death.

Am I allowed to defer estate taxes owed?

A portion of estate taxes owing may be deferred but only on the part attributable to a qualified closely-held business. Estate taxes attributable to the remainder of the estate or to an estate without a qualified closely-held business cannot be deferred.

Computing the estate tax due for an estate with a closely-held business is the same as for other estates. The ability to defer the estate taxes attributable to a closely-held business is done by electing an installment plan consistent with §6166 of the Internal Revenue Code.

The purpose of an installment election is to prevent the forced liquidation of a closely-held business. The election allows for an installment payment plan over ten or fifteen years. Typically an installment payment plan involves paying the accrued interest only on the deferred tax for the first five years. For the next ten years the estate pays 1/10th of the deferred tax (principal), plus the accrued interest. There is no penalty for paying an installment plan off early.

For more details, including the qualifications for an installment election consistent with §6166, see the Estate Tax Installment Plans for Closely-Held Businesses page.

Are gifts taxable for Washington estate tax purposes, if so, where do I report gifts on the estate tax return?

Generally, outright gifts given prior to the date of death are not taxable for Washington estate tax purposes.

However, federal gift tax paid or payable within three years of the date of death is included as an asset of the estate on Schedule G - Transfers During Decedent’s Life. The federal gift tax paid or payable is reported on the schedule, not the amount of the gift.

Also, any transfers that meet one of the four Internal Revenue Code provisions listed below are considered part of the decedent’s estate because the decedent retained a life interest. If the decedent had any of these four types of assets prior to death and then gave the asset outright within three years of death, those gifts are added back into the value of the gross estate and reported on Schedule G - Transfers During Decedent’s Life.

The IRC provisions are:

1. 26 USC §2036 - Transfers with retained life estate;
2. 26 USC §2037 - Transfers taking effect at death;
3. 26 USC §2038 - Revocable transfers; or
4. 26 USC §2042 - Proceeds of life insurance.

A gift made beyond three years of the date of death or that does not meet one of the four IRC provisions listed above is not included in the Washington gross estate.

Is there an election for qualified terminable interest property (QTIP)?

Yes. For details see the Estate Tax Qualified Terminable Interest Property page.

Is there a farm deduction, if so, how much can be deducted?

The value of farm property (land, stock, produce, equipment, etc.) can be deducted from the taxable value of an estate as long as the value of farm property comprises at least half of the total adjusted value of the estate and meets other statutory requirements. The farm deduction is unlimited and is in addition to the applicable exclusion amount.

A tenant farmer may qualify for the farm deduction if the requirements are met.

The definition of a farm includes stock, dairy, poultry, fruit, furbearing animals, and truck farms; plantation; ranches; nurseries; ranges; greenhouses or other similar structures used primarily for the raising of agricultural or horticultural commodities; and orchards and woodlands.

For more details, including the requirements for the farm deduction, see the Estate Tax Deduction for Farms page.

Is there a deduction for family-owned business interests?

Yes, there is a deduction for qualified family-owned business interests (QFOBI). The QFOBI must meet certain requirements in order to be deducted from the estate.

The heirs that the QFOBI is passed to must continue the operation of the trade or business in regard to the QFOBI for three years. If the heirs do not continue operation of the trade or business, there is an additional tax that will be due.

For more details, including the requirements for the QFOBI deduction, see the Estate Tax Qualified Family-Owned Business Interests Deduction page.

What are the estate tax funds used for?

The estate tax funds are deposited into the Education Legacy Trust Fund.

The Education Legacy Trust Fund provides funding for:

• The student achievement fund for reducing class sizes, professional development of teachers, extended learning such as before- and after-school programs, and pre-kindergarten learning.
• Learning assistance program to help kindergarten through 12th-grade students who are not up to standards.
• Higher education (which includes monies for financial aid, supporting additional enrollment of students, adult basic education programs in community colleges, work-study programs, etc).
