(AP) — An Omaha man who created an elaborate scheme to avoid paying more than $422,000 in taxes has been given a year and a day in prison.

Federal prosecutors said Monday that 50-year-old Michael Haffke also must serve two years of supervised release after he leaves prison. Haffke had pleaded guilty to fraud conspiracy.

Prosecutors say Haffke created more than 40 different business entities as part of his scheme to hide taxable income and didn’t file any personal returns for several years. Prosecutors say Haffke later filed returns in 2012 for the tax years 2003 through 2007 and paid the taxes owed.

As part of his plea agreement, Haffke must work with the IRS to determine whether he owes any more taxes and must pay those taxes, if any.
