IRS Revenue Agent Indicted for Filing False Tax Returns

For Immediate Release
U.S. Attorney's Office, District of Massachusetts

BOSTON – A Revenue Agent for the United States Internal Revenue Service (IRS) was indicted yesterday by a federal grand jury in Boston for allegedly filing false personal tax returns for three years.

Ndeye Amy Thioub, 67, of Swampscott, was indicted on three counts of filing false tax returns and three counts of filing false tax returns as an employee of the United States. Thioub was previously arrested and charged by criminal complaint in March 2024. 

According to the charging documents, Thioub was hired in 2006 as an Internal Revenue Agent in the IRS Large Business and International Division. As a Revenue Agent, Thioub planned and conducted examinations of tax returns using extensive and specialized knowledge of accounting techniques, practices and investigative audit techniques to examine and resolve various tax issues of individuals and business organizations. As a result of her education, training and experience, Thioub was highly knowledgeable about tax law. In addition, Thioub received yearly training in IRS Employee Tax Compliance, which instructs that IRS employees must comply with their tax obligations, including timely filing accurate tax returns and payment of taxes due.

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. 

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. The charge of filing a false tax return by an employee of the United States provides for discharge from employment and a sentence of up to five years in prison, followed by one year of supervised release and a $10,000 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.

Acting United States Attorney Joshua S. Levy; Harry Chavis, Jr., Special Agent in Charge of the Internal Revenue Service Criminal Investigation, Boston Field Office; and Christopher J. Gust, Acting Special Agent in charge of the U.S. Department of Treasury Inspector General for Tax Administration, Northeast Field Division made the announcement today. Assistant U.S. Kristina E. Barclay of the Public Corruption & Special Prosecutions Unit is prosecuting the case.

The details contained in the charging documents are allegations. The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
