What is KYC? Know Your Customer Explained for Businesses

KYC stands for Know Your Customer. It refers to the process businesses use to verify the identity of their clients before and during a business relationship. If you have ever been asked to show your passport or driver licence when opening a bank account, you have been through a KYC process.

For decades, KYC was primarily a requirement for banks and financial institutions. In recent years — and in Australia following the Tranche 2 reforms effective 1 July 2026 — KYC obligations have been extended to a much broader range of businesses including accountants, lawyers, real estate agents and others.

Why Does KYC Exist?

KYC requirements exist primarily to combat money laundering, terrorism financing and fraud. When businesses know exactly who their clients are — verified through reliable and independent sources — it becomes significantly harder for criminals to use those businesses to move illicit funds or hide their identities behind false personas.

Financial regulators worldwide, including AUSTRAC in Australia, FINTRAC in Canada, FinCEN in the United States and the FCA in the United Kingdom, all require certain businesses to implement KYC procedures as part of their anti-money laundering programs.

What Does KYC Involve?

A complete KYC process typically includes four elements:

1. Customer Identification

Collecting the basic identifying information about the client: full legal name, date of birth, residential address and a unique identifier such as a passport or driver licence number.

2. Identity Verification

Confirming that the information provided by the client is accurate using reliable and independent sources. This can be done electronically — by checking details against government databases — or through document verification and biometric matching.

3. Beneficial Ownership

For business clients such as companies and trusts, KYC requires identifying and verifying the individuals who ultimately own or control the entity. In most jurisdictions, this means identifying any individual who directly or indirectly owns 25 percent or more of the business.

4. Ongoing Monitoring

KYC is not a one-time event. Businesses are required to monitor their clients throughout the relationship, updating information when circumstances change and screening for new risks including PEP status and sanctions matches.

What is the Difference Between KYC and AML?

KYC (Know Your Customer) is a component of AML (Anti-Money Laundering) compliance. AML is the broader framework of laws, regulations and procedures designed to prevent money laundering. KYC is one of the key tools within that framework — it ensures that businesses know who they are dealing with before and during any regulated transaction.

Think of AML as the overall program and KYC as one of its essential processes.

What Happens If You Don't Do KYC?

The consequences of failing to comply with KYC requirements vary by jurisdiction but are consistently serious. In Australia, penalties for non-compliance with the AML/CTF Act include:

• Civil penalties of up to $18.5 million per breach for corporations
• Criminal prosecution for serious or wilful non-compliance
• Reputational damage from AUSTRAC enforcement actions, which are publicly reported
• Exposure to civil liability if your business is found to have facilitated money laundering

How to Do KYC Online

Modern KYC platforms make compliance significantly easier and faster than traditional paper-based methods. With VerifyID Online, the process works like this:

1. You add a client and send them a secure link from your firm dashboard
2. The client completes the verification on their phone in under three minutes
3. The platform checks their details against government databases, authenticates their ID document and verifies their face biometrically
4. You receive the result instantly, with a PDF certificate and full audit trail stored for 7 years

The entire process is digital, documented and defensible — exactly what regulators expect to see.

How Often Do You Need to Re-Verify Clients?

Under Australian AML/CTF rules, businesses must conduct periodic reviews of client information at a frequency determined by the client's risk rating:

• High-risk clients — review every 12 months
• Medium-risk clients — review every 2 years
• Low-risk clients — review every 3 years

VerifyID Online tracks these review dates automatically and sends reminders when a client is due for a periodic review.

Do Small Businesses Need to Do KYC?

Whether a small business needs to complete KYC depends on what services it provides. In Australia, any business providing a "designated service" under the AML/CTF Act is required to implement a KYC process. Following Tranche 2, this now includes sole trader accountants, single-partner law firms and individual real estate agents — not just large organisations.
