Youri Khomitch, Victoria Chambers, Oleksandra Hawkins and Alexander Sokolovski were jailed in 2010 after an HMRC investigation found they stole £6m from the taxpayer by setting up fake accountancy services to eastern European workers.
The group used workers’ identity documents and fake identities to submit more than 3,000 false self assessment returns.
The group was led by married couple Khomitch and Chambers. The couple used the money to buy a number of properties including a luxury £3m home in Kent, plus holidays in Japan, Dubai, New York and Thailand, expensive gold jewellery and diamonds, plus a breast enlargement operation for Chambers.
HMRC officers also seized £380,000 in unpaid cheques when they arrested Chambers and Khomitch in 2010.
The four have been told to make combined payment of £976,000, or face an extended prison spell of nine years in prison.
David Cowie, assistant director of HMRC said, “This gang stole identities and vast amounts of money to live a luxury lifestyle that they neither earned nor deserved. We were determined that they did not leave jail to enjoy that lifestyle again, and had all assets held by the defendants restrained prior to confiscation proceedings.
“HMRC works tirelessly not only to identify fraud, but to actively seek the profits of fraud,” he added. “If these criminals do not pay up, they will serve extra time in jail, and still owe the money when they are released.”
