Is Lottery Winnings Tax Free in Australia? The Full Answer

The short answer is yes: lottery winnings are tax-free in Australia. The Australian Taxation Office does not treat prize money from Australian lotteries as assessable income. You do not include it in your tax return.

The longer answer is that several things that happen after you win are taxable. Understanding the distinction matters if the win is significant.

Why lottery winnings are not taxed

This treatment applies regardless of the amount. A $200 million Powerball win and a $50 Saturday Lotto win are both tax-free for the same reason.

What IS taxable after you win

Interest and investment income

If you deposit your winnings in a savings account, the interest earned is assessable income. It is taxed at your marginal rate, the same as interest from any other source. A $1 million win sitting in a term deposit at 5 percent generates $50,000 in assessable income per year.

Dividends and share income

If you invest in shares and receive dividends, those dividends are assessable income. Franking credits from Australian company dividends apply as normal.

Capital gains

If you use your winnings to buy an asset (shares, an investment property, crypto) and later sell it for a profit, capital gains tax applies to the gain. The 50 percent CGT discount applies if you hold the asset for more than 12 months.

The original prize money is not a capital gain because you did not buy it. But the profit from selling an asset you bought with prize money is.

Rental income

If you buy an investment property with your winnings and rent it out, the rental income is assessable. Normal deduction rules apply.

State-by-state: are the rules different?

No. Tax on lottery winnings (or the absence of it) is a federal matter under the Income Tax Assessment Act. All states and territories follow the same rules. There is no additional state-level lottery tax anywhere in Australia.

Overseas lottery prizes: different rules

If you win a foreign lottery or gambling prize, the tax treatment may be different. Some countries withhold tax on lottery prizes at source. The United States, for example, withholds federal tax on prizes above certain thresholds before paying out. If you win an overseas lottery, the withholding may be recoverable under a tax treaty or may not, depending on the country.

In some cases, foreign lottery winnings may be assessable in Australia as foreign income. This is a specialist area and you should seek specific advice if you win overseas.

The Centrelink distinction

This is where many people are caught off guard. Lottery winnings are tax-free. They are not Centrelink-free.

Services Australia assesses assets and deemed income for means-tested payments. Once a lottery win is in your account, it is an asset. It is subject to the assets test and the income test (via deeming) for any Centrelink payment you receive.

This is separate from the ATO's treatment entirely. The two government agencies operate under different legislation with different purposes.

Goods and services tax (GST)

Lottery prizes are not subject to GST. The ticket price includes the lottery operator's GST component, but the prize payment itself is not a taxable supply.

Do you need to declare a lottery win on your tax return?

No. Lottery winnings are not included as income in your individual tax return. You do not need to disclose the prize amount anywhere on the return.

What you do need to declare is any income earned from investing or holding the winnings: interest, dividends, rent, and capital gains, in the usual places on the return.
