GAMBLING WINS AND THE ATO: THE TAX REALITY
When it comes to gambling in Australia, most players assume their wins are tax-free. That’s true in many cases, but a recent SMH article reports that a recent win by the Australian Taxation Office (ATO) at the Administrative Review Tribunal shows the situation isn’t always so simple. Whether you’re betting casually or regularly, the way you handle your winnings can determine whether they remain untaxed or turn into a liability.
Under Australian tax law, gambling winnings are generally not considered taxable unless you are classified as a professional gambler. However, the ATO takes a strict approach to unexplained deposits and bank transactions. If you can’t prove where your money came from, the ATO can treat it as assessable income and tax it accordingly. Unlike in criminal law, the ATO has no burden of proof, and it can assume the deposits are taxable, with the responsibility falling on the taxpayer to prove otherwise.
That was exactly the issue in a case involving a regular casino and sports gambler who claimed he was living off his gambling wins. While he argued he wasn’t running a business and therefore had no reason to keep records, the ATO disagreed. Without bank statements, betting records, or receipts to verify the source of his deposits, the funds were treated as taxable income. The lesson here is clear: unless you can demonstrate on the balance of probabilities that your deposits came from gambling, the ATO may simply impose tax and penalties.
With increased data-matching, the ATO can now track PayPal and other payment platforms often linked to betting apps. Financial institutions also flag large transactions under anti-money laundering rules. Even if you avoid depositing your winnings, the ATO can apply an “asset betterment test,” comparing your lifestyle and assets to your reported income. If there’s a mismatch, they can estimate your earnings and tax you on the difference.
While casual gambling may often escape the tax net, unexplained wealth will not. Keeping accurate records of a betting history and winnings isn’t just good practice but may prove to be the only shield between you and a costly dispute with the ATO.
