Businesses have until Monday to provide a detailed annual statement on their compliance with new anti-money laundering and counter-terrorism financing laws, The Australian Financial Review reports.

According to the AFR, the Australian Transaction Reports and Analysis Centre (AusTRAC) has sent letters to some 17,000 businesses -- including banks, foreign exchange dealers, financial services firms and gambling companies -- to remind them to lodge their reports by the March 31 deadline.

"Reporting on the 31st of March is not optional," AusTRAC's Thomas Story said. "All the government policy principle says is that if you take 'reasonable steps' AusTRAC will not initiate action. If reasonable steps aren't taken, we can."

The warning comes as the federal government considers its proposed second tranche of laws dealing with real estate agents, accountants, lawyers and jewellers, the paper reports.
