The fiduciary of the estate or trust is responsible for filing and seeing to the payment of any federal or Washington state estate taxes owed by the estate. Generally whether, and to what extent, there is an estate tax liability should be made early on because the general deadline for filing the returns falls nine months after the decedent’s date of death. The preparation of an estate tax return dovetails with preparation of the Inventory because it is based upon the date of death values of all property included in the decedent’s gross estate, whether probate or non-probate. The professional probate lawyers and associates at Lyons Sullivan can assist the fiduciary in the preparation of federal and Washington State estate tax returns or refer to a competent tax advisor.
