Client who is 83 years old received 55K from a property owned by father and step mother. Client's father has been deceased over 40 years ago and stepmother over 5 years., and did not have any contact with them for decades. Client did not know of the existence of the property.  Client is the only nlearnt of the unclaimed funds from a firm that tracks potential owners, and earns a fee. The state of Georgia made a tax lein sale to settle the outstanding tax and the remaining $55K  was paid out to client.

Question? Is the $55K taxable or not?

Thanks in advance .
