He is free on $20,000 bond after an initial appearance Monday before Magistrate Jane Virden in Greenville.
Harrison, 56, faces up to 70 years in prison and $500,000 in fines if convicted on all counts.
A six-page federal indictment claims Harrison intentionally under-reported his and his spouse's joint taxable income by $216,061 for calendar years 2005-2008.
He also is accused of failing to pay more than $1.4 million Pontotoc furniture manufacturer Miss-Eaton Inc. withheld from its employees' paychecks during 10 quarters from 2006-2008.
The indictment accuses him of using company funds for his own personal benefit while he was chief financial officer from June 2000 until about August 2008.
He was scheduled to answer formal charges Thursday before Virden.
The indictment against him was issued Feb. 22 but it was just made public.
State records for Miss-Eaton Inc. show the business incorporated in 1962 as Miss Eaton Corp. then changed hands in 1977, now with officers Greg Marx, president/director, Daniel Galloway, treasurer/secretary, and Kevin Mills, vice president, all of Pontotoc. Records also show a Sept. 13, 2012, notice of intent to dissolve the corporation for failure to file its 2012 annual report.
The business is described as a wood office furniture manufacturer.
Marx did not respond to a Daily Journal call with questions about Harrison and the business.
