Ndeye Amy Thioub, of Swampscott, was charged with filing false tax returns. Thioub will appear in federal court in Boston at 2 p.m. today. According to the charging documents, Thioub has been employed by the IRS for over 17 years. In her current position as a Revenue Agent assigned to the Large Business and International Division of the IRS, Thioub conducts independent field examinations and related investigations of complex income tax returns filed by large businesses, corporations and organizations. Thioub has extensive and specialized knowledge of and training in accounting techniques, practices and investigative audit techniques. She is also responsible for examining and resolving various tax issues of individuals and business organizations that may include extensive national and/or international subsidiaries. In addition to her IRS position, Thioub worked as a visiting instructor at Salem State University, teaching college-level classes that included instruction on the verification of records; valuation and analysis of accounts; the importance of financial accounting and financial statements; professional standards; and ethics, professional responsibilities and legal liabilities issues facing auditors. It is alleged that Thioub filed false personal tax returns for tax years 2017, 2018 and 2019. It is further alleged that, for each year, Thioub filed a false Schedule C claiming a business loss from a purported “import and export” business she claimed to have. As a result, the claimed net loss was carried over to her personal IRS Form 1040s and used to reduce Thioub’s adjusted gross income and ultimate tax liability. Specifically, Thioub allegedly underreported her total income by approximately $42,805 in 2017, $20,324 in 2018 and $27,063 in 2019. The charge of filing a false tax return provides for a sentence of up to three years in prison, followed by one year of supervised release and a $100,000 fine. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.
