Suspicious matter reports for accountants: when and how to lodge

A suspicious matter report, or SMR, is due within 3 business days of forming a suspicion that a matter may involve money laundering, terrorism financing or proceeds of crime. Within 24 hours if it involves terrorism financing. The clock starts at the suspicion, not at proof.

What counts as a suspicion

You do not need evidence. A reasonable suspicion on reasonable grounds is enough. Typical triggers for an accounting firm:

  • Funds that do not match the client's known income or business.
  • Reluctance to explain the source of funds, or explanations that change.
  • Unusual use of cash, or requests to structure payments under AU$10,000.
  • A third party funding or directing the matter for no clear reason.
  • Complex structures with no commercial purpose.
  • A client who refuses identification or offers documents that look wrong.

How to lodge

  1. Record the suspicion in your own system the day it forms: what you saw, when, who noticed. This starts your timeline.
  2. Lodge the SMR through AUSTRAC Online within 3 business days (24 hours for terrorism financing).
  3. Rate the client high risk and apply enhanced due diligence, or decide not to continue.
  4. Keep the record for 7 years.

Tipping off

Do not tell the client, or anyone outside the firm, that you have lodged or are considering an SMR, where doing so could prejudice an investigation. The reformed rule focuses on that harm, but the safe practice in a small firm is simple: discuss it only with your compliance officer and AUSTRAC.

You can still act for the client

Lodging an SMR does not by itself require you to stop acting. It requires you to report, to reassess the risk and to keep watching.

Questions people ask
