"I figured it must be some sort of a scam," Thomas said.
But sure enough Thomas is owed a refund worth $18,000.
"I can't understand it," Thomas said. "They have my address, they hear from me every year."
The fact is there are thousands of taxpayers in Southern California who are owed millions of dollars in tax refunds that never got to them.
"People send in their tax returns and then maybe they move," said IRS Senior Tax Consultant Tom Cavagnero. "And so we send out their refund check and it comes back from the post office as undeliverable."
