Another area often misunderstood by taxpayers — and one that’s increasingly attracting the IRD’s attention — is cryptoassets (Bitcoin being the most well-known example). As with FIF income, taxpayers might be surprised at how much information the IRD has about their cryptoasset holdings through international information exchanges.
This level of scrutiny will increase significantly when New Zealand adopts the OECD’s Crypto-Asset Reporting Framework (CARF) from 1 April 2026. CARF will operate similarly to the current international information exchanges that enable the IRD to detect foreign income.
So, how are cryptoassets taxed in New Zealand? For tax purposes, they aren’t considered money or a financial arrangement. The IRD’s view is that cryptoassets are a form of property that is, in most cases, acquired solely with the intention of making a gain from disposal. This means any disposal of cryptoassets, including exchanges for other cryptoassets, will normally be taxable.
Whether cryptoassets are always held to sell for profit is debatable. However, unless there’s a specific reason for acquiring them (such as “staking” where cryptoassets might generate income from being held rather than on disposal), it’s a difficult position to argue against.
What does this mean? In short, any time you sell cryptoassets — whether converting them to a fiat currency like NZD or exchanging them for other cryptoassets — the IRD considers it a taxable event. If you make a gain, it’s taxable; if you incur a loss, it’s deductible.
The challenge lies in calculating gains or losses, as you need to convert the amounts paid and received into NZ currency on the respective transaction dates.
You can see where this is headed. If you have a few transactions involving a well-known cryptocurrency, this might be straightforward. However, if you’re regularly trading and exchanging between different cryptoassets, as well as converting to or from NZD or foreign currencies, it can become very complex.
As with FIF income, if you have cryptoasset income that hasn’t been disclosed to the IRD, it’s much better to report it before they discover it. Some cryptoasset brokers can generate tax reports to help with these calculations. However, it’s important that you can verify that these reports are accurate, as you’re responsible for the information you include in your tax returns.
