Wilson, of 23 counts of aiding and assisting the preparation of false and fraudulent tax returns. According to United States Attorney Gerard M. Karam, Marcellus operated a tax-preparation business in Chambersburg called M&M Confident Multi Services from 2013 to 2016. In an effort to increase refund amounts and generate business, Marcellus regularly included false numbers on the returns he prepared and filed. The returns falsely claimed, among other things, the federal fuel-tax credit, business losses, and deductions for charitable gifts and unreimbursed employee expenses. The case was investigated by the Internal Revenue Service Criminal Investigation. Assistant U.S. Attorneys Carlo D. Marchioli and Paul J. Miovas are prosecuting the case. The maximum penalty under federal law for each count is three years of imprisonment, a term of supervised release following imprisonment, and a fine. A sentence following a finding of guilt is imposed by the Judge after consideration of the applicable federal sentencing statutes and the Federal Sentencing Guidelines.
