For a person who gambles for fun in New Zealand, winnings are generally not treated as taxable income, and losses cannot be claimed. The exception is gambling as a business or a profession. This is general information, not tax advice; Inland Revenue is the authority.
A quick decision path
The general position
Under New Zealand’s general tax rules, money won from gambling as a pastime is not income, so you do not declare it. That is the same whether the winnings come from a licensed local operator or an overseas site: the source of the money is not what decides it, the nature of your activity is.
The exception
If gambling is carried on as a business, or you are a professional gambler in substance, the position can change. Features that point that way are regular, systematic play with a view to profit, a business-like operation and gambling as your main source of income. Few people are in that position, and anyone who thinks they might be should speak to a registered tax agent.
What losses do
Losses from recreational gambling are not deductible against other income. A bad month is a bad month, not a tax event.
Records worth keeping
- Account statements and transaction history from each operator.
- Bank or wallet statements showing deposits and withdrawals.
- Any correspondence about a withdrawal that was held or refused.
Records matter if Inland Revenue asks about unexplained deposits into your bank account, and for verification, see the document checklist.
Two things this page does not cover
Your tax residency (a New Zealand resident is taxed on a different basis from a non-resident), and any tax imposed by the country where the operator is based. Check both with a professional. For the official position, see Inland Revenue’s guidance on gambling income.
Questions readers ask
Do I have to declare overseas casino winnings?
The general rule treats recreational winnings the same wherever they come from: not income. If you are unsure whether the exception applies to you, ask Inland Revenue or a tax agent.
Does the Online Casino Gambling Act 2026 change my tax?
It licenses operators; it is not a tax statute. Check Inland Revenue for any change.
