Less than two per cent of Domino's Pizza stores in NSW have been audited by the state government for unpaid payroll tax since the company's underpayment of workers was exposed in 2017. The disclosure comes as the opposition and crossbench claim that Revenue NSW has failed to actively audit companies linked to wage scandals, resulting in lost revenue for the state's critical services and infrastructure. A NSW parliamentary committee on Monday heard four of 222 Domino's franchises were audited by Revenue NSW in 2016 and 2017, resulting in just two franchisees paying $37,683 in unpaid tax.
