AU Gambling Tax Guide 2026 — Winnings, CGT, Professional Gambler Test
A complete plain-English guide to the Australian tax position on gambling: why casual winnings are non-assessable, when the ATO treats you as running a "gambling business", what happens if you fund gambling with crypto, and the record-keeping you actually need. Sourced from ATO rulings.

TL;DR — the AU tax position on gambling
- Recreational gambling winnings are non-assessable under ATO Ruling IT 2655. You don't declare pokies wins, blackjack wins, or casino cashouts as income.
- You can't deduct gambling losses either. Losses are personal expenditure, not deductible.
- Crypto disposal is a CGT event. If you buy USDT at A$1.50 and spend it at A$1.60 on a casino deposit, that's a A$0.10 CGT gain (per unit).
- Professional gamblers ARE taxable. If the ATO determines you're carrying on a "gambling business" (rare), winnings become income and losses become deductible. Very high bar.
- Bank statements show your gambling activity. Non-assessable doesn't mean invisible — the ATO can request records during audit.
The foundational rule: ATO Ruling IT 2655 (1991)
Australia's tax treatment of recreational gambling has been settled since the ATO published Income Tax Ruling IT 2655 — Betting and gambling — whether taxpayer carrying on business of betting or gambling in 1991. The ruling states that a "mere punter" — someone who gambles for entertainment, without conducting gambling as a business — has winnings that are not ordinary income and therefore not assessable.
The ATO's reasoning: gambling winnings are the result of chance rather than the exercise of skill or effort in the ordinary sense of carrying on a business. Under Australian income tax principles, receipts must derive from activity that could be characterised as "the production of income" to be assessable. Recreational gambling doesn't meet that test.
The rule applies regardless of:
- How much you win (a A$1M pokies jackpot is still non-assessable).
- How often you win (regular play doesn't itself convert winnings to income).
- Whether you play at an AU-licensed or offshore operator.
- Whether you deposited in AUD, crypto, voucher or bank transfer.
Corollary: losses aren't deductible. If winnings aren't income, losses aren't a deductible expense.
The professional gambler exception
IT 2655 explicitly considers whether a taxpayer might be "carrying on the business of betting or gambling" — in which case winnings become ordinary income and losses become deductible business expenses. The ATO's test isn't a bright line; it's a multi-factor evaluation:
- Systematic and organised approach. Do you have a documented system, staking plan, bankroll methodology? Not just "I'm good at blackjack".
- Scale and repetition. Are you gambling professionally-scale (full-time, or serious part-time)? Casual weekly play doesn't qualify.
- Skill vs chance. Sports-arbitrage betting, professional card counting, poker circuit play — activities with a genuine skill edge — carry more risk of ATO business classification than pokies.
- Intent to profit. Are you gambling to make a living, or to entertain yourself?
- Business-like conduct. Do you run this like a business — separate accounts, tax records, staff, structured planning?
In practice, the ATO treats fewer than 1 in 10,000 gamblers as running a gambling business. Case law includes:
- Babka v Federal Commissioner of Taxation (1989) — professional punter's earnings held to be assessable because he engaged with betting as a business.
- Evans v Federal Commissioner of Taxation (1989) — a punter's winnings held not assessable despite substantial volume, because activity wasn't "business" in character.
- Prince v FCT (1959) — foundational case on distinguishing gambling for entertainment from carrying on a betting business.
Practical implication: if you're wondering whether you might be classified as a professional gambler, and you're asking that question casually — you almost certainly aren't. The bar is very high, and professional gambler status is generally something the taxpayer seeks (because losses become deductible), not something the ATO imposes on casual players.
Crypto and gambling — the CGT overlay
The ATO treats cryptocurrencies (BTC, ETH, USDT etc.) as CGT assets. This is independent of gambling — the same rules apply whether you spend crypto on gambling, groceries, or a Tesla.
A CGT event occurs whenever you dispose of a crypto asset — including spending it. When you deposit USDT at a casino, you've disposed of USDT. The tax treatment:
- Calculate your cost base. The AUD value of the crypto when you acquired it.
- Calculate the disposal value. The AUD value of the crypto when you spent it at the casino.
- Difference = capital gain or capital loss. If positive, it's a taxable gain (potentially with the 50% CGT discount if held over 12 months). If negative, it's a capital loss you can carry forward.
Worked example:
- You buy 1,000 USDT on 1 March for A$1,500 (USDT price = A$1.50 per unit). Cost base per USDT = A$1.50.
- You deposit 1,000 USDT at a casino on 15 May when USDT is trading at A$1.60. You've disposed of 1,000 USDT for A$1,600 of value.
- Capital gain = A$1,600 − A$1,500 = A$100. This goes on your tax return under CGT.
- What happens next in the casino (win or lose) is separately non-assessable per IT 2655.
- If you later withdraw 1,200 USDT (winnings), you've acquired 1,200 USDT at market value on the withdrawal date. This becomes your new cost base for those coins.
- When you later convert those 1,200 USDT back to AUD, another CGT event occurs based on the difference between withdrawal-day price and conversion-day price.
Because USDT tracks the USD, per-transaction CGT gains/losses are typically small (cents to dollars per transfer). But the record-keeping obligation is real and the ATO can request records during a crypto-focused audit.

Record-keeping — what to actually save
Even though recreational winnings are non-assessable, keep records. The ATO can and does request bank statements, crypto exchange records, and casino statements during audits, and the professional-gambler test is retrospective.
Minimum viable record set:
- Bank statements covering all AU accounts you use for gambling (deposits + withdrawals).
- Crypto exchange statements from any exchange you buy/sell/hold crypto with (Independent Reserve, CoinSpot, BTC Markets, Kraken, Swyftx, Binance etc.).
- Crypto wallet activity logs — Tronscan / Etherscan / mempool.space exports of your wallet's transaction history.
- Casino cashier / transaction records if the operator provides them (some allow CSV export of your deposit/withdrawal history).
- KYC documents submitted to any casino (retain the copy you sent, in case of dispute).
Retention period: 5 years from the date you lodged the tax return is the ATO's standard record-keeping rule. If you have crypto activity, err on the side of 7 years.
Practical setup:
- Once a month, download PDF statements from your bank and exchange.
- Once a year, use a crypto tax service (Koinly, Crypto Tax Calculator AU, Syla) to reconcile every crypto disposal and generate a CGT report.
- Keep a running spreadsheet of casino deposit/withdrawal dates and amounts if you want to reconstruct your own audit trail.
Special cases
Betting on races or sports
Same rule — recreational punters' winnings are non-assessable. Bookmakers may issue Group Certificates for professional-scale accounts; consult a tax agent if this applies to you.
Lottery / lotto wins
Non-assessable per IT 2655. Interest earned on the winnings (once banked) is assessable at your marginal rate.
Poker winnings
Non-assessable for recreational players. Professional poker players (e.g. on the pro tour) face the professional-gambler test.
Skill-game arbitrage or matched betting
Increased risk of ATO business classification because there's a documented skill component. Consult a tax agent if this is your primary income source.
Foreign-domicile casino winnings paid in USD or EUR
Non-assessable per IT 2655 (nationality of the operator doesn't change the tax treatment). But foreign currency held long-term is a CGT asset with its own reporting requirements if converted to AUD later.
Gifts to family from gambling winnings
Non-assessable for the giver; the recipient doesn't declare a gift as income. But gifted amounts may affect Centrelink or other means-tested support if either party receives payments.
What triggers ATO attention on gambling activity
The ATO doesn't audit casual gamblers routinely. Common triggers for review:
- Large unexplained deposits into your bank. A A$50k cashout landing suddenly can prompt a bank review that leads to ATO notification.
- Consistent income patterns from gambling. If your bank statement shows a steady weekly A$3,000 inflow labelled as casino cashouts, the ATO may review whether you're carrying on a business.
- Crypto activity flagged by exchange reporting. AU-licensed crypto exchanges report high-volume transactions to AUSTRAC, which can be shared with the ATO.
- Third-party notification. Family disputes, business partnership dissolution, and public disclosures sometimes trigger ATO reviews.
Practical implication: gamble within your means, keep records, and if you have large one-off cashouts that will be visible on your bank statement, be ready to explain them as gambling winnings (not income) with the receiving casino's transaction record as evidence.
Common misconceptions
"I only pay tax on winnings above A$10,000"
False. There is no threshold for recreational-gambling winnings. They're non-assessable regardless of amount.
"I need to declare winnings on my tax return"
False. Recreational winnings don't appear anywhere on your return.
"If I use crypto, I don't have any AU tax obligations"
False. Crypto disposal is a CGT event. Even at the small stablecoin scale, you have record-keeping obligations.
"Losses can offset other income"
False. Gambling losses aren't deductible against other income for recreational players.
"Offshore casino means the ATO can't see it"
False. The ATO can subpoena AU-side bank and crypto exchange records. Offshore casinos are opaque to the ATO but the AU-side money flows aren't.
"The ATO will treat me as a professional gambler because I win"
False. The ATO treats a tiny fraction of gamblers as running a business. Professional status is typically sought by the taxpayer (to deduct losses), not imposed.
Common questions
Do I need to report a A$100,000 pokies jackpot?
The jackpot itself is non-assessable. But interest earned on the money once you bank it is assessable, and any onward crypto disposal is a CGT event.
Are lottery winnings taxable in Australia?
No. Non-assessable per IT 2655 like other gambling winnings.
What if I gamble with money that came from illegal or undeclared sources?
That's a separate issue — the source-of-funds question. Winnings from the gambling activity are still non-assessable, but the ATO or AFP can pursue you separately for undeclared source income.
What if I'm not sure I'm a "recreational" or "professional" gambler?
If you're asking casually, you're almost certainly recreational. Talk to a registered tax agent if you're generating meaningful full-time income from gambling and want clarity — but understand that professional status is a two-edged sword (income becomes taxable in exchange for loss deductibility).
Can I write off my casino welcome bonuses on tax?
No — welcome bonuses aren't income and don't affect your tax position at all.
What tax software handles gambling correctly?
Most consumer tax software (myTax, TurboTax, myDeductions) handles it correctly by not asking about gambling activity for recreational players. For crypto disposal reporting, use Koinly / Crypto Tax Calculator AU / Syla and import into myTax.
