No. The rules apply when an accounting practice provides certain activities known as designated services.
Whether the AML/CTF requirements apply depends on the type of work being undertaken, not simply on the fact that you use an accountant.
Preparing a standard tax return or providing general tax advice may not be a designated service on its own. However, business accounting engagements often involve additional services, entities and transactions that bring the client relationship within the AML/CTF framework.
