Greek authorities have uncovered a large-scale tax fraud scheme involving fake invoices, creating a financial loss of more than €12 million to the state. Police investigations revealed a network of 370 so-called “ghost companies” used to submit fraudulent tax refund claims. To avoid detection, the group continually created new ghost companies, changing managers frequently to maintain the facade of activity. Outstanding withheld tax amounts are estimated at €3,771,005.32, while the total cost to the Greek state—including halted collection processes due to investigations—amounts to €12,132,695.20. The scheme even involved using ghost companies to issue fake invoices to real businesses, inflating expenses and losses for tax evasion purposes.
