In May the IRD trialled a campaign in Auckland called "declare it all or risk everything" to discourage cash jobs, warning offenders could be heavily punished. One tradie reportedly received $68,000 in cashies. In some cases there were one-off cash jobs for as much $30,000.
While the campaign created a genuine concern from cashie receivers to report in their earnings, the IRD is also calling for anyone who knows anything to blow the whistle on those who are not declaring cash jobs.
Evasion of tax can result in a fine of up to $50,000 or jail plus the tax, penalties and interest.
Cashies can hurt business in several other ways. Insurance will not cover undeclared jobs. If you don't have Cover Plus Extra and have an accident, ACC will only pay out at the level of declared income - not that going under the table. And not declaring cash can affect the sales value of a business.
It is possible that the crackdown will help IRD gather information on property speculators who have not declared taxable gains on property transactions.
With every dollar the IRD spends on this activity, it yields six in return.
