The Australian government could boost its coffers by many billions of
dollars and improve compliance by increasing third-party reporting on
taxpayers' incomes and withholding tax requirements. International
studies show that relying on taxpayers' honesty and co-operation
typically results in a shortfall, according to Richard Highfield, senior
adviser with the OECD's Centre for Tax Policy and Administration. He
estimates increasing third-party reporting on business-related income in
particular – including business-to-business and business-to-consumer
sales, share transactions and property rentals – would significantly
stem "revenue leakage."Australia has "lots of room" for improvement,
agrees the US national taxpayer advocate, Nina Olson, but experience
shows third-party reporting also can be counterproductive, she warns.
