When a Lancaster County man got his mail last weekend, he found two items. The first one, Barry Tangert says, was a refund check from the federal government for over $900. The second was from the Pennsylvania Department of Revenue.The letter was an income tax billing notice, which showed that Tangert owed the state more than $34 billion — $34,576,826,561.47, to be exact."I knew it was an obvious blunder. I don't even make over $100,000 a year, so there's no way I could owe anywhere near that," Tangert said. Earlier this year, Tangert's tax preparer noticed an error on his 2022 return and filed an amendment. Tangert thought everything was taken care of until he got the notice."I don't know if it was a computer glitch in the transmission or if it was an input error from my tax preparer," Tangert said. Tangert reached out to the Pennsylvania Department of Revenue and spoke to a customer service representative."The first thing he said was, 'You had a good year.' And I said, 'I wish,'" Tangert said.Tangert said he didn't get any clarification about how the error happened.News 8 reached out to the Department of Revenue on Tangert's behalf. After our initial phone call, we were told the situation had been resolved and that the error was an isolated incident that stemmed from the wrong numbers being inputted into the system.
