An estate is a legal entity created when a person dies. The deceased’s estate is a separate legal entity for federal tax purposes. Thus, an estate is used to pay any debts owed by the decedent and the remaining balance of the assets are then distributed to the beneficiaries.
An estate consists of real and/or personal property of the deceased person, and this estate exists until the final distribution of assets is made. An estate is indeed required to obtain an EIN.
