You need to file an income tax return - IR3 when you have taxable income from a cryptoasset activity. Before you can add your cryptoasset net income (or loss) in your income tax return you must:

  • calculate the New Zealand dollar value of your cryptoasset transactions
  • work out your cryptoasset income and expenses.

There are other rules you need to be aware of if your cryptoassets are trading stock.
