Dentist found guilty of filing false tax returns

Kaufman, who represented himself, said he spent years researching tax law to "find the truth."

"I never wanted to be in this position," he added.

Assistant U.S. Attorney Joan E. Burnes said Kaufman's actions were proof he knew that he was illegally trying to circumvent paying taxes.

Burnes said Kaufman placed his house in the name of a "fictitious trust" when the IRS attempted to collect back taxes. A return he filed in 2008 was fraudulent, and he illegally tried to claim $865,041 in refunds, she said.

Kaufman changed the bank into which he deposited his business receipts at least four times, and he tried to get the IRS to give him money by submitting what he called "bonded promissory notes," she said. One was for $7 million.

Burnes said Kaufman filed the paperwork with the IRS and claimed that it created an account under his name, out of which he told the IRS it had to pay a civil judgment of $340,000, a bank loan of $75,000, and his auto loan, among other debts.

Kaufman was also arrested last year by state police after he and a second man allegedly used a baseball bat and a metal bar to attack two men who attempted to repossess his car. That case is pending.
