Here's what you need to know.
Todd Chrisley claimed the tax evasion and bank fraud allegations stem from an ex-employee.
"It all started back in 2012, when we discovered that a trusted employee of ours had been stealing from us big time," Todd wrote. "I won't go into details, but it involved all kinds of really bad stuff like creating phony documents forging our signatures, and threatening other employees with violence if they said anything. We even discovered that he bugged our home."
Todd continued, "Needless to say, we fired the guy and took him to court — and that's when the real trouble started."
Todd said he and Julie were cleared of any wrongdoing.
According to Todd, the ex-employee "took a bunch of his phone documents to the U.S. attorney's office and told them we had committed all kinds of financial crimes, like tax evasion and bank fraud."
He wrote that "got [the authorities'] attention, all right, but once we had a chance to explain who [the ex-employee] was and what he'd done to us, [the U.S. Attorney's office] realized it was all a bunch of nonsense and they sent him on his way."
But the Chrisleys' former employee didn't give up.
Todd wrote that the ex-employee somehow "persuaded a different set of investigators at the U.S. Attorney's office not only to reopen the case but also to grant him immunity from prosecution for his own crimes and bring charges against us."
As a result of this, Todd wrote that he and Julie will likely be "named in a federal indictment charging us with tax evasions and probably a bunch of other financial crimes as well."
Todd insists he and Julie have "done nothing wrong."
Todd wrote that he was "telling you all this now because we have nothing to hide and have done nothing to be ashamed of."
"Not only do we know we've done nothing wrong, but we've got a ton of hard evidence and a bunch of corroborating witnesses that proves it," he added.
