San Antonio Couple Sentenced to Federal Prison for Tax Evasion

SAN ANTONIO - A San Antonio woman was sentenced to 15 months in federal prison for tax evasion and aiding and abetting.

According to court documents, Rachel Olivia Markum, 41, and her husband, Robert Franklin Markum Jr., 47, prepared and signed a false and fraudulent form 1040 joint tax return for calendar year 2016, which was then submitted to the Internal Revenue Service. The fraudulent tax return reported the couple's sole income as gross receipts or sales from the business Camping and Fishing Outlet as $3,530,473, while she was aware that the true amount of gross receipts exceeded $4 million.

Rachel pleaded guilty May 28, 2024, to one count of tax evasion and aiding and abetting. Robert pleaded guilty on April 1, to one count of tax evasion, and was sentenced to 27 months in federal prison on Aug. 28. The husband and wife were also ordered to pay $359,108 in restitution.

"This sentencing underscores the serious consequences of defrauding the federal government through false tax returns," said U.S. Attorney Jaime Esparza for the Western District of Texas. "By concealing hundreds of thousands of dollars from the IRS, this married couple betrayed the integrity of our tax system. We will continue to protect the financial interests of the United States with our IRS Criminal Investigation partners and hold accountable those who seek personal gain through deceptive, illegal means."

"Robert and Rachel Markum created false identities and businesses to hide their income from the IRS, but they failed to realize that money always leaves a trail. Their years in prison will give them an opportunity to reflect on their actions," said Acting Special Agent in Charge Lucy Tan for IRS Criminal Investigation's Houston Field Office. "Prosecuting federal tax crimes remains a priority in Texas, and our strong partnership with the U.S. Attorney's Office for the Western District of Texas underscores our commitment to holding tax criminals accountable."

IRS-CI investigated the case. Assistant U.S. Attorney Justin Chung prosecuted the case.
