Revenue cracking down on cash paymentsFriday 20 December 2013 22.01
An investigation by the Revenue Commissioners into businesses paid in cash yielded tens of millions of euro in the first eight months of this year.
RTÉ News has learned the inquiry - the Shadow Economy Project - looked at several industries, ranging from building firms to scrap metal merchants to landlords and nursing homes.
Almost €82m was recouped by tax inspectors between January and August last.
The biggest amount came from landlords, who had to pay €21m.
White collar cash accounted for €16.5m, which includes cash payments to doctors, dentists, vets, solicitors, accountants, physiotherapists and teachers giving grinds.
Around €17m was paid back from those working in construction.
Couriers had to pay €2m and the security industry €5m.
Nursing homes had a bill of €730,000 and €220,000 was recovered from those selling scrap metal.
Garages handed over €460,000, while the cash-for-gold sector has so far yielded €55,000.
