The owner of a Southern California janitorial company pleaded guilty to underreporting payroll by more than $1 million in an effort to reduce his workers’ compensation premiums, the Ventura County District Attorney’s Office announced.

Victor Vega, 53, faces up to 10 years in prison and could be ordered at a June 5 sentencing hearing to pay $428,867 in restitution.

Vega, the owner of Vega’s Cleaning Service, pleaded guilty to four felony charges of making false statements to reduce the cost of work comp insurance. County prosecutors in a statement said Vega systematically underreported more than $1 million in payroll between December 2010 and February 2015.
