Do I Need to Report Cash Transactions Over $10,000?

One of the most common questions we hear is: "Do all transactions over $10,000 need to be reported?" The answer is more nuanced than you might think, and understanding the distinction can save you from unnecessary reporting while ensuring you meet your genuine obligations.

Under Australia's AML/CTF Act, only physical cash payments of $10,000 or more require separate threshold transaction reports (TTRs) to AUSTRAC. This is a crucial distinction: electronic transfers, bank transfers, cheques, and other non-cash payment methods don't trigger threshold transaction reporting requirements, regardless of the amount involved.

So if your client pays you $50,000 by bank transfer, you don't need to file a threshold transaction report. However, if they walk into your office with $10,000 in physical cash, that's a different story—you're required to report it to AUSTRAC within 10 business days.

The $10,000 threshold applies to individual transactions and to multiple cash transactions that you know or have reasonable grounds to suspect are related and total $10,000 or more. This prevents people from circumventing the requirement by breaking large cash payments into smaller amounts.

It's worth noting that while electronic transfers don't require threshold reporting, you should still report any transaction—regardless of amount or payment method—if you form a suspicion that it might involve money laundering, terrorism financing, or other serious crimes. Suspicious matter reports (SMRs) operate on a different basis entirely and aren't limited to cash or specific dollar amounts.

What About Funds in the Banking System?

Here's a question that trips up many professionals, particularly lawyers and accountants who manage trust accounts: "If my client's funds transfer from their bank to our trust account, do I need to verify whether the bank received cash?"

The short answer is no. Once funds are in the banking system—moving electronically between bank accounts—it's the bank's AML responsibility to manage cash-related obligations. Banks are sophisticated reporting entities with their own comprehensive AML/CTF programs, and they're already tracking and reporting cash deposits into customer accounts.

Your compliance obligations focus on your direct relationship with your client and any suspicious indicators you identify through that relationship. You're not expected to trace back through the banking system investigating how funds entered your client's account. That's the bank's job.

Your role is to understand your client, assess the risks they present, and identify any red flags that emerge from your dealings with them. If something about the transaction or the client's explanation doesn't add up, that's when you should dig deeper—but you're not responsible for auditing the banking system's cash handling.

This distinction is important because it keeps your compliance efforts focused and proportionate. You have enough to manage without taking on responsibilities that properly belong to other parts of the financial system.

How to Ask About Source of Funds Without Causing Offense

One of the most uncomfortable aspects of AML compliance is asking clients about their source of funds. Many professionals worry about insulting clients or damaging relationships by questioning where their money comes from. It's a legitimate concern—nobody likes feeling they're under suspicion.

The key is framing your inquiry as a legal requirement rather than a personal judgment. Try something like: "I'm required by law under AML legislation to verify the source of funds for this transaction. Can you provide documentation showing where these funds came from?"

Most clients understand regulatory requirements once you explain them. In today's world, AML checks are increasingly common—people encounter them when opening bank accounts, buying property, or engaging professional services. You're not singling them out; you're following the same legal requirements that apply across the financial sector.

It also helps to explain briefly that these requirements protect everyone—they keep the Australian financial system safe from criminals and ensure legitimate businesses like yours aren't unknowingly used for money laundering. When clients understand the "why" behind your questions, they're generally cooperative.

If a client becomes defensive or refuses to provide source of funds information, that itself can be a red flag. Legitimate clients with legitimate funds usually have no problem explaining where their money came from and providing evidence. Resistance or evasiveness might indicate something worth examining more closely.

What Evidence Can You Request?

When verifying source of funds, you have considerable flexibility in what types of documentation you can request. The goal is to obtain credible evidence that demonstrates where the money legitimately came from.

Acceptable source of funds documentation includes:

Bank statements showing the accumulation of funds over time or the receipt of a specific payment. These are often the simplest form of evidence, particularly for salary earners or business owners with regular income streams.

Sale of asset documentation such as contracts of sale for property, vehicles, shares, or other investments. If your client sold their investment property and is now using those proceeds, the settlement statement provides clear evidence.

Employment records including payslips, employment contracts, or letters from employers confirming income. This works well for clients funding transactions from their regular earnings.

Inheritance documentation such as probate documents, executor letters, or estate distribution statements. Inherited wealth is a common and entirely legitimate source of funds.

Loan documents from banks or other legitimate lenders showing the client borrowed the funds. The loan agreement and drawdown evidence demonstrate where the money came from.

Business sale contracts and completion statements if the client has sold a business. Business sales often generate significant sums that clients then deploy for other purposes.

Investment statements showing the sale or redemption of shares, managed funds, or other investment products. Your client's investment portfolio is a perfectly legitimate source of funds.

The type of evidence you request should be proportionate to the transaction value and risk. For a straightforward $20,000 conveyancing matter where the client is a local professional you've worked with before, simple bank statements might suffice. For a $2 million transaction involving a new client with complex offshore structures, you'd want more comprehensive documentation.

Remember that source of funds verification isn't about creating barriers or making compliance unnecessarily difficult—it's about having a reasonable, documented basis for believing the funds are legitimate. Use your professional judgment, assess the specific circumstances, and request evidence that gives you confidence you're not facilitating money laundering.
