Intestacy refers to the condition of an estate of a person who dies without a will, and owns property that is worth more than their outstanding debts.

A testamentary trust is a legal entity that manages the assets of a deceased person in accordance with instructions in the person's will.

It's important to know how to file a deceased person's Form 1040 or 1040-SR because unfortunately, death doesn’t relieve one’s obligation to file a final federal income tax return.
