Piotr Seredynski, from Dolny, was charged after Customs officers discovered 29,000 Glen's vodka labels bearing UK duty stamps in his car.
He was stopped by officers as he arrived at Dover's eastern docks from France . The tax that could have been evaded through the illegal use of the stamps is around ú150,000.
Seredynski was sentenced for fraudulent evasion of excise duty at Maidstone Crown Court on May 11.
A Revenue & Customs assistant chief investigation officer said: "This type of tax fraud is perpetrated by organised criminal gangs. Buying illegal spirits helps fund their other activities."
He added: "Honest traders need to be able to operate on a level playing field, and not be undercut by those flouting the law."
