Aquil Ahmed, 60, an accountant, who owned a Bentley and bought properties in the UK, USA and Turkey, as a result of these actions, was imprisoned for seven years and eight months.

HMRC revealed that he took multiple foreign holidays, including trips to Dubai and the Monaco Grand Prix, using the money gained from defrauding HMRC of VAT, Income Tax, National Insurance Contributions and Construction Industry Scheme deductions.

Mr Ahmed and co-conspirators Aquil Victor Shearer, 43, a construction services company director; and Christopher Azzopardi, 37, a payroll administrator employed by Ahmed, carried out the fraud for two and a half years.

His Honour, Judge Macdonald QC, said the “loss to HMRC is just another way of stealing from citizens of the UK”, adding that the men “took millions to spend on themselves”.

The court heard Mr Azzopardi was in debt. Mr Ahmed paid him around £60,000 a year, double a usual bookkeeper’s wage, for his role in the fraud. No tax was paid on his salary.

The men attempted to hide their fraud by using a complex network of companies and bank accounts in the UK and offshore, officials said, but their crimes were uncovered by investigators from HMRC.

Mr Ahmed employed Christopher Azzopardi to operate payroll services for clients through various ‘keepers’ companies, supposedly calculating wages and paying any tax due to HMRC through the PAYE and CIS systems. Clients were charged VAT on these services, but neither the VAT nor the PAYE and CIS deductions were paid across to HMRC, officials said.

Chris Gill, Assistant Director, Fraud Investigation Service, HMRC, said: “These men were driven by greed, abusing systems that are designed to ensure workers are paid correctly and taxes paid to HMRC. They were all professionals who knew they were breaking the law, but as an accountant Ahmed was in a position of trust, making his part in the conspiracy even more deplorable.

“These criminals thought they’d created a sophisticated fraud, and that by operating through numerous UK and offshore companies, they could hide what they were doing. But our investigations are thorough, and with assistance from authorities in Gibraltar, we unravelled the many layers they’d created and they are now paying the price for their crimes.

“This investigation shows that regardless of the resources of those involved, or how hard they try to hide their crime, no one is beyond our reach.”

HMRC stated: “Victor Shearer’s company, Leaner Logistics, supplies short-term contractors to the construction industry, mainly in London and the South East. Often providing hundreds of workers at a time, he turned to Mr Ahmed’s Keepers companies to run his payroll and CIS.

“Over time, Mr Shearer introduced other clients to the payroll company, who also used this fraudulent scheme. But rather than pay the tax and National Insurance to HMRC, the three men stole the money to fund Mr Ahmed and Mr Shearer’s lavish lifestyles.”

Mr Ahmed pleaded guilty to three counts of cheating the public revenue at Maidstone Crown Court on 14 June 2016. Mr Shearer and Mr Azzopardi were found guilty of three counts of cheating the public revenue on 21 July 2016, after a six week trial at the same court.

Mr Shearer was also found guilty of laundering his £1.2 million cut through a bank account in Gibraltar. The court heard how vast sums were spent by Mr Shearer, through bank transfers, cash withdrawals and by debit card, on property and high-living, ski holidays, cars and treating friends, family and clients.

Mr Azzopardi was sentenced to 4 years’ imprisonment, while Mr Shearer got 7 years 6 months, when they appeared at Maidstone Crown Court on Friday 21 October.

Mr Ahmed and Mr Shearer channelled money through Gibraltar, the Channel Islands, the UAE, USA, Turkey and various property transactions. They are both subject to financial restraint orders.
