An "insolvent estate" -- the term for a situation in which the total value of an estate's assets are less than the debts and liabilities owed  -- can lead to tax issues. Being tasked with handling an insolvent estate can be stressful but the information in this guide will help you through the process.

Generally, if a decedent’s estate is insufficient to pay all the decedent’s debts, the debts due the United States government must be paid first. Both the decedent’s federal income tax liabilities at the time of death and the estate’s income tax liability are debts due the United States. The personal representative of an insolvent estate is personally responsible for any tax liability of the decedent or of the estate if he or she had notice of such tax obligations or had failed to exercise due care in determining if such obligations existed before distribution of the estate’s assets and before being discharged from duties.

The extent of such personal responsibility is the amount of any other payments made before paying the debts due the United States, except where such other debt paid has priority over the debts due the United States. The income tax liabilities need not be formally assessed for the personal representative to be liable if he or she was aware or should have been aware of their existence.

For estate tax purposes, if there is no executor or administrator appointed, qualified, and acting within the United States, the term “executor” includes anyone in actual or constructive possession of any property of the decedent. It includes, among others, the decedent’s agents, and representatives; safe-deposit companies, warehouse companies, and other custodians of property in this country; brokers holding securities of the decedent as collateral; and the debtors of the decedent who are in this country.
