Anti-Money Laundering (AML) and KYC Guides: The Complete Hub

This hub brings together Learnsignal's guides on anti-money laundering (AML), know your customer (KYC), sanctions and financial crime. It is written for accountants, auditors and finance professionals, and for students preparing for regulated roles. Money laundering lets criminals turn the proceeds of crime into apparently legitimate money, and professionals who advise on structures, handle client funds or prepare accounts can be used without knowing it. Regulators therefore expect firms to understand their risks, check who their clients are, watch for unusual activity and report suspicion.

Use the sections below to find the right guide. If you are starting out, read the basics first and then move to the topics that match your role. If you are building a firm-wide programme, work through due diligence, ownership, sanctions, monitoring and governance in turn. You can also explore our CPD courses for structured training that counts towards professional development.

Frequently asked questions

What is the difference between AML and KYC?

AML is the full set of laws, controls and procedures that stop criminals using the financial system. KYC, or know your customer, is one part of it: the process of identifying clients and understanding who they are and why they want your services.

Do accountants need AML training?

In many countries accountants are covered by AML law, and regulators expect staff to be trained. The details depend on where you work, so check your supervisor's rules and our country guides above.

Where should a small firm start?

Start with a written firm-wide risk assessment, then build client onboarding checks, a way to escalate concerns to a named person, and a training and record-keeping routine.
