Complaint: Veteran IRS agent claimed thousands of dollars in false expenses

During the tax years of 2017 to 2019, Thioub filed false personal tax returns and claimed thousands of dollars in fraudulent business expenses, according to the U.S. Treasury Inspector General for Tax Administration.

The complaint alleges that Thioub also filed a false Schedule C, which is used to report income and expenses a taxpayer operated or a profession the taxpayer practiced as a sole proprietor. Thioub allegedly claimed a business loss from an "import/export" business Thioub said she operated, the complaint says.

"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 U.S. Attorney's Office said.

Thioub had reported that the alleged businesses resulted in net losses of $42,805 in 2017, $20,324 in 2018, and $27,063 in 2019, according to the complaint.
