Cases where tax may require explanation

The Australian Tax Office (ATO) actively monitors financial transactions related to gambling, especially if there are signs that the declared income does not match actual expenses or suspicious transactions. In some cases, the tax authority has the right to demand official explanations and supporting documents.

The main cases where the ATO may request an explanation are:
  • 1. Large deposits or withdrawals from casinos

Amounts significantly higher than the declared annual income.
Discrepancy between the volume of game transactions and the financial situation of the player.

2. Frequent transfers between gaming accounts and bank

Constant transactions with large amounts, not supported by documents.

3. Winnings abroad

Receiving income from foreign casinos and online platforms without being reflected in the declaration.

4. Regular profit from the game

Systematic wins that can be qualified as a business activity.

5. Cash transactions without source confirmation

Replenish casino accounts or withdraw large amounts of cash.

6. Signals from AUSTRAC

Receipt of information on suspicious transactions related to money laundering or financing of illegal activities.

7. Data from foreign tax authorities

Exchange of information under international agreements (CRS).

What the ATO can ask for:
  • Bank and game account statements.
  • Documents on the origin of funds (contracts, receipts, inheritance or insurance payments).
  • Copies of past tax returns.
  • Proof of identity and registration on gaming platforms.

Recommendations for preparing for a possible request:
  • 1. Keep records of all financial transactions related to gambling.
  • 2. Keep documents for a minimum of 5 years in accordance with ATO requirements.
  • 3. Do not mix gaming and personal funds.
  • 4. Declare foreign winnings and transfers.
  • 5. If in doubt, consult a tax specialist.

Consequences of failure or untimely response:
  • Accrual of tax arrears.
  • Penalties for failure to provide information.
  • Increased control in subsequent periods.

Conclusion
Requesting an explanation from the ATO is not always a sign of a violation, but it is always a signal to provide transparent and documented information. A prepared player minimizes the risk of fines and additional checks.
