Do You Pay Tax on Casino Winnings in Australia?

The ATO's General Position on Gambling Winnings

The Australian Taxation Office (ATO) takes the position that gambling winnings received by a recreational gambler are not ordinary income and are not subject to income tax. This applies whether you win at a land-based casino, an online poker room or an offshore site. The ATO's published guidance states that winnings from gambling are generally not taxable, and gambling losses are generally not deductible.

The reasoning is that recreational gambling is a private activity, not a business or income-producing activity. A one-off win — even a large one — does not change that classification on its own.

This position is consistent with long-standing Australian case law. Courts have distinguished between a person who gambles for recreation and one who carries on a gambling business. The distinction turns on factors such as whether the activity is systematic, whether the person has a profit-making intention backed by a commercial method, and whether gambling is their primary livelihood.

When Gambling Winnings Can Become Taxable: Professional Gamblers

The ATO recognises that some individuals gamble in a sufficiently organised, systematic and business-like manner that their activity constitutes carrying on a business. In that case, net winnings are assessable income, and net losses may be deductible against other income (subject to non-commercial loss rules).

Factors the ATO and courts have considered include:

— Whether the person has a genuine profit-making intention and a commercial system or strategy.

— Whether the activity is carried on in a regular, organised and repetitive way.

— Whether gambling is the person's primary or significant source of income.

— The scale of the activity and the degree of skill applied.

No single factor is decisive. A person who bets large amounts regularly is not automatically a professional gambler; equally, a person who earns most of their income from poker or sports betting may be treated as one even if they do not think of themselves that way.

If you believe your gambling activity might meet this threshold, the ATO recommends seeking advice from a registered tax agent. The boundary is fact-specific and the consequences of misclassification — in either direction — can be significant.

Do No-KYC Offshore Casinos Report to the ATO?

This is a question many players ask, and the honest answer requires separating what is publicly known from what is speculative.

Australia participates in the OECD's Common Reporting Standard (CRS), an international framework under which financial institutions in participating countries automatically exchange account information with tax authorities in account holders' home countries. The ATO receives CRS data from participating jurisdictions and uses it to identify undisclosed foreign income and assets.

However, whether a specific offshore casino or its payment processor falls within CRS reporting obligations depends on how it is classified under the rules of its home jurisdiction, and on whether that jurisdiction participates in CRS. Many offshore gambling operators are licensed in jurisdictions such as Curaçao or Anjouan. Curaçao has committed to CRS participation, but the practical scope of reporting by gambling operators — as distinct from banks and investment accounts — is not something this guide can confirm without jurisdiction-specific legal analysis.

What is clear is that the ATO has broad data-matching capabilities. It receives information from Australian banks, payment processors and digital currency exchanges. If you deposit to or withdraw from an offshore casino through an Australian bank account, PayID or a regulated Australian crypto exchange, those transactions may be visible to the ATO through domestic data-matching, regardless of what the casino itself reports.

Using a no-KYC casino does not make your financial transactions invisible to Australian authorities. The casino's reporting obligations and your own tax obligations are separate questions. If you have undisclosed foreign income or assets, the ATO's voluntary disclosure process is the appropriate route; this guide does not provide legal or tax advice.

Crypto Withdrawals and Capital Gains Tax

Some offshore casinos pay out winnings in cryptocurrency — Bitcoin, Ethereum, stablecoins or other tokens. This adds a layer of Australian tax complexity that is separate from the question of whether the gambling winnings themselves are taxable.

The ATO treats cryptocurrency as a capital gains tax (CGT) asset, not as currency. This means that every time you dispose of cryptocurrency — including when you convert it to AUD, exchange it for another token, or use it to pay for something — you may trigger a CGT event. The capital gain or loss is calculated as the difference between the cost base (what you paid, or the AUD value at the time you received the crypto) and the proceeds (the AUD value at the time of disposal).

Applied to casino winnings: if a casino credits your account with 0.01 BTC when Bitcoin is worth A$100,000 (so A$1,000 received), and you later convert that BTC to AUD when Bitcoin is worth A$120,000 (so A$1,200 received), the A$200 increase is a capital gain. If you held the asset for more than 12 months, the 50% CGT discount may apply.

Importantly, the ATO's position is that receiving crypto as a form of payment or reward establishes a cost base at the market value on the date of receipt. You need to record the AUD value of any crypto you receive on the day you receive it. Without those records, calculating your CGT position accurately is difficult.

This applies even if the underlying gambling winnings were not taxable income. The CGT rules operate independently.

Note: stablecoins pegged to AUD or USD are still treated as CGT assets by the ATO unless the ATO issues specific guidance to the contrary. Check the ATO's current cryptocurrency guidance for the most recent position.

Record-Keeping Practical Steps

Even if you believe your gambling winnings are not taxable, keeping records is useful for two reasons: it supports your position if the ATO ever queries your affairs, and it is essential if you hold crypto.

For recreational gamblers with no crypto involvement, the ATO does not require you to declare winnings or keep gambling records. However, if your gambling activity is substantial, keeping a simple log of sessions, wins and losses helps demonstrate the recreational nature of the activity if questions arise.

For anyone receiving crypto winnings, the ATO expects you to keep records of:

— The date of each transaction.

— The AUD value of the crypto at the time of receipt (your cost base).

— The AUD value at the time of each disposal.

— The nature of the transaction (received as winnings, converted to AUD, exchanged for another token, etc.).

Many Australian crypto exchanges provide transaction histories that include AUD values. If you use a self-custody wallet and receive crypto directly from a casino, you will need to source the AUD price from a reliable exchange rate record on the relevant date.

1. Record the date and AUD value of any crypto received as winnings on the day of receipt.
2. Record the date and AUD value of any crypto disposal (conversion, exchange or spend).
3. Calculate the difference between cost base and proceeds for each disposal.
4. If you held the asset for more than 12 months, note this for the potential 50% CGT discount.
5. Keep records for at least five years from the date you lodge the relevant tax return.
6. If your gambling activity is large-scale or your primary income source, consult a registered tax agent before lodging.

Getting Advice

This page explains the general ATO framework as published on ato.gov.au. It is not legal or tax advice, and it does not account for your individual circumstances.

If any of the following apply to you, speaking with a registered tax agent or accountant is worthwhile:

— Gambling is a significant or primary source of your income.

— You have received or disposed of cryptocurrency in connection with gambling.

— You have accounts or winnings held offshore that you have not previously declared.

— You are unsure whether your activity crosses the threshold into professional gambling.

The ATO's website includes a find-a-tax-professional tool, and the Tax Practitioners Board maintains a public register of registered tax agents at tpb.gov.au.
