Illegal immigrant gets eight-year prison sentence for $89 million payroll tax fraud scheme

The Department of Justice announced on Thursday that Mario Flores, an illegal immigrant from Honduras, was sentenced to eight years in prison for fraudulently cashing $89 million in a payroll scheme between 2015 and 2022, which involved employing other illegal immigrants working in the United States. Flores also filed false tax documents with the IRS to avoid detection of his illegal financial scheme. He was sentenced on Wednesday.

Court documents show that while in the country illegally, Flores created multiple shell companies to create and manage an “unlicensed check cashing and cash courier service business.” Over the course of seven years, Flores’s scam companies cashed checks from construction industry workers totaling around $89 million, while also charging these workers a percentage of the check’s value as a fee for doing so, according to the DOJ. 

Flores’s scheme enabled construction contractors who ran the companies to pay employees in cash without filing and paying the required payroll taxes. Records show that, altogether, it resulted in “a total loss to the United States of more than $38 million,” according to the Department of Justice.

“Today, we held an illegal alien from Honduras accountable for a brazen scheme that stole more than $38 million from American taxpayers to facilitate the employment of illegal aliens,” said Assistant Attorney General Colin M. McDonald of the Justice Department’s National Fraud Enforcement Division. 

McDonald linked the fraudulent criminal case to one of the many problems associated with the previous administration’s tolerance for illegal immigration and blasted the politicians who permitted this for harming the country’s workers and taxpayers. He stressed accountability for anyone in the country illegally, intending to defraud the country and exploit the country’s previously unchecked border policies.  

“This case exposes how unchecked illegal immigration fuels widespread payroll tax fraud and underground economies that harm American workers and taxpayers,” McDonald said. “This sentence sends a strong message: those who exploit our open borders, cheat the U.S. Treasury, and violate federal laws will face justice.”

In addition to defrauding the government with phony payment records and an illegal check-cashing company, Flores’s scheme “facilitated the employment of illegal aliens working in the United States,” noted the Department of Justice. He also defrauded insurance companies with fake workers’ compensation claims through “providing false and fraudulent information to the insurers about … the number of workers covered by the insurance and the amount workers were paid.”

“Flores pleaded guilty to one count of conspiracy to defraud the United States and one count of conspiracy to operate an unlicensed money transmitting business,” read a press release issued by the Department of Justice.

Flores had multiple coconspirators in the scheme, who were previously sentenced to varying punishments, with one person receiving 4 years of probation and another receiving a 17-year prison sentence, the Justice Department said. Each was also ordered to pay several million dollars in restitution. 

Homeland Security Investigations Acting Executive Associate Director John Condon warned that anyone seeking to defraud the government through such illegal schemes would suffer harsh consequences.

“Homeland Security Investigations is committed to protecting the integrity of our financial system and enforcing our nation’s laws,” Condon said. “Those who orchestrate large-scale payroll tax fraud and facilitate the illegal employment of unauthorized workers will be held accountable. HSI, alongside IRS Criminal Investigation and our federal, state, and local partners, remains dedicated to dismantling schemes that defraud the United States and undermine the integrity of our workforce.”
