How to file your tax return with a win through myGov

In Australia, tax returns can be filed online through the myGov service, which is integrated with the Australian Tax Office (ATO). If your winnings are subject to taxation (for example, in the case of a professional game, foreign income or related gambling earnings), it is important to correctly reflect them in the form.

Step 1. Determine whether to declare winnings

Not required: amateur play in licensed Australian casinos, with no sign of business.
Required: professional game, income from streaming gambling, winnings from abroad, recognized as taxable.
If in doubt, you can request from ATO Private Ruling to clarify obligations.

Step 2. Prepare documents

Receipts and checks of casinos or online platforms.
Bank statements with receipt of funds.
Reports on rates and results.
Documents on taxes paid abroad (for international winnings).

Step 3. Log on to myGov

1. Go to [myGov] (https ://my. gov. au).
2. Log in using myGovID or other login methods.
3. Make sure your account is linked to the ATO ("Link your services" section).

Step 4. Start filling out the declaration

1. Go to the ATO - Income tax section.
2. Select Lodge tax return.
3. Specify the tax year for which the declaration is filed.

Step 5. Completion of income section

Go to the Income block.
In the Other income section, select Gambling and prize winnings (or a similar item).
Specify the total amount of the taxable winnings.
If the game is recognized as a business, income is reflected in the Business income section, and losses in Business expenses.

Step 6. Attach supporting information (if required)

myGov does not always require documents to be uploaded, but the ATO can request them later.
It is better to have electronic copies of all confirmations in advance.

Step 7. Check the data

Make sure your winnings match your bank statements and casino documents.
Please make sure you have correct information about taxes paid abroad.

Step 8. Sending the declaration

Click Lodge to submit the form.
Save the confirmation of sending (PDF or screenshot).

Step 9. Waiting for processing

The ATO usually reviews the online declaration within 2-4 weeks.
If discrepancies or suspicious amounts are found, ATO will send a request for clarification.

Frequent errors when filing through myGov:
  • Specify winnings that are not taxable (extra burden).
  • Skipping overseas income.
  • Lack of documentary evidence of the source of funds.

Recommendations:
  • 1. With significant amounts of winnings, contact a tax agent to verify the declaration.
  • 2. Keep records of all transactions throughout the year to simplify filling out the form.
  • 3. Don't delay serving until the last day to avoid technical glitches.

Conclusion
Filing a gambling return through myGov is a process available to any taxpayer, but requires accuracy in determining taxable income. Proper preparation and correct completion of the form reduces the risk of fines and requests from the ATO.
