As part of the probate process, the executor or administrator is responsible for identifying and addressing any outstanding debts and taxes of the estate. This involves notifying creditors, reviewing claims, and paying off valid debts using estate funds. The executor or administrator must also determine the estate's tax obligations, including income taxes and estate taxes, if applicable. They work with tax professionals to prepare and file the necessary tax returns and ensure that any tax liabilities are settled from the estate's assets.
