Bookkeepers are required by law to be supervised for anti-money laundering by an awarding body. Awarding bodies include (but are not limited to):
HMRC
ICB
IAB
AAT
If they suspect money laundering is taking place within a firm they are required by law to report it.
When we take on a new client we perform identification checks, anti-money laundering checks, and risk assessments before undertaking any work.
