Crypto in New Zealand: Trading Stock vs Investment
New Zealand is often described as having no capital gains tax, and that is technically true. But it leads many crypto holders to a dangerous conclusion: that their gains are tax-free. In reality, the Inland Revenue Department (IRD) taxes most crypto profits as ordinary income. The key question is whether your crypto is treated as trading stock or an investment.
No CGT, but income tax still applies
Because there is no separate capital gains tax, the IRD assesses crypto under the ordinary income rules of the Income Tax Act 2007. If you acquired cryptoassets with the purpose of selling or exchanging them, the profit is income and taxed at your marginal rate, which can reach 39%. The absence of a CGT regime does not mean the absence of tax.
The intention test
The IRD's default position is that most people buy crypto intending to sell it for a profit. That intention, formed at the time of acquisition, is what makes gains taxable. Unlike property, there is no bright-line time period that turns a gain tax-free. Holding for years does not, on its own, exempt the profit.
Trading stock vs investment: what the IRD looks at
Where crypto activity is frequent and business-like, it may be treated as trading stock, which changes how and when profits and even unrealised holdings are accounted for. The IRD weighs several factors:

Frequently asked questions
If I just buy and hold, are my gains tax-free? Not necessarily. If you acquired with the intention to eventually sell for profit, the gain is generally taxable income when you dispose of it, regardless of how long you held.
Is the IRD actually checking? Yes. From 1 April 2026, New Zealand begins CARF reporting, giving the IRD far greater visibility over local and offshore exchange activity. Voluntary compliance is the safer path.
