The anti-money laundering regulator Austrac will impose a levy of A$30.3 million for estimated costs in the 2013/14 financial year.This cost will be borne by the 13,000 Australian businesses that are enrolled with Austrac as reporting entities under the Anti-Money Laundering and Counter-Terrorism Financing Act. Levies are tiered, according to the size of the reporting entity. The big banks will pay around $2 million for their share of the costs.The estimated cost of Austrac's regulatory functions for the 2013/14 financial year has been calculated using an activity-based costing model. Its regulatory activities include engagement with reporting entities, compliance work, processing transaction reports, analysis of transaction data, liaison with partner agencies and policy development.The good news for reporting entities is that Austrac has trimmed its budget. The 2012/13 levy was $32.2 million.
