What is the estate tax?
The estate tax is a tax on the right to transfer property at the time of death. A Washington decedent or a non-resident decedent who owns property in Washington State may owe estate tax depending on the value of their estate.
Estate tax forms, rules and information are specific to the date of death.
>> Deaths May 17, 2005 through December 31, 2013
>> Deaths on or after January 1, 2014
Either the Washington estate tax forms and estate tax payment or a request for an extension to file the Washington estate tax return and an estimated payment are due nine months after the decedent’s date of death.

Estate tax changes
The Department has updated the estate tax return and created addendums to align with 2013 legislation. For dates of death on or after January 1, 2014, an estate that meets the Washington filing threshold must send a complete Washington estate tax filing including the estate tax return, any applicable addendums and all supporting documentation. When the estate is required to file an estate tax return with the Internal Revenue Service, a copy of the Federal Form 706 should be included with the Washington estate tax forms.
