Daniel Lewis Hendon, the former owner of Danny's Family Car Wash, received the sentence plus another year of home confinement when he was punished in November.
Authorities say Hendon rehired workers who were fired after a federal audit found nearly half of the company's 1,900-person workforce had presented insufficient or ineligible records when they were hired.
In pleading guilty to a conspiracy charge, Hendon admitted he turned a blind eye toward his business' hiring of immigrants who were in the country illegally.
Hendon has since divested himself of the business.
