New Zealand has no general capital gains tax, so plenty of people assume the profit on their Bitcoin is theirs to keep. Usually it isn’t. The way crypto is taxed in New Zealand is different from almost any other investment, and 2026 is when that stopped being theoretical: Inland Revenue (IRD) now receives transaction data straight from exchanges, and the global Crypto-Asset Reporting Framework is in force.
We sell hardware wallets, and tax is one of the questions customers ask us most. This guide covers how the IRD taxes cryptoassets, which transactions are taxable and which aren’t, the rates, and what the new reporting rules mean for you. We’ve kept the legislation out and stuck to what a holder needs to stay compliant without overpaying.
Important: This article is general information, not personalised tax advice. Everyone’s situation differs. For decisions about your own return, talk to a chartered accountant or tax adviser.
Crypto is taxed as income, not capital gains
This is the part most people get wrong. New Zealand has no separate capital gains tax, but that doesn’t make crypto profits tax-free. The IRD classifies cryptoassets as property, not money and not a financial arrangement. When you dispose of that property at a profit, the profit is ordinary income, taxed at your normal marginal rate.
The IRD’s view is that most people buy crypto intending to sell or exchange it at some point. Where that intention exists, the profit on disposal is taxable income. It’s a broad test and the IRD applies it broadly, so if you bought hoping the price would rise, assume your gains are taxable.
There is a narrow exception for assets genuinely bought for a long-term purpose other than sale. The IRD sets a high bar for that argument, and most everyday investors should treat their disposals as taxable.
What counts as a taxable event in New Zealand?
A “disposal” isn’t only cashing out to New Zealand dollars. You can owe tax without a single dollar reaching your bank account.
| Transaction | Taxable in NZ? |
|---|---|
| Selling crypto for NZD | Yes, profit is income |
| Trading one coin for another (e.g. BTC → ETH) | Yes, this is a disposal |
| Spending crypto on goods or services | Yes, a disposal at market value |
| Buying an NFT with crypto | Yes, you’ve disposed of the crypto |
| Receiving staking or mining rewards | Yes, income at NZD value on receipt |
| Receiving an airdrop intended for sale | Yes, income on receipt |
| Getting paid a salary in crypto | Yes, income at NZD value |
| Buying crypto with NZD | No |
| Simply holding (“HODLing”) | No |
| Moving crypto between your own wallets | No, not a disposal |
Crypto-to-crypto swaps catch out the most people. Swapping Bitcoin for Ethereum on an exchange feels like moving things around, but the IRD treats it as disposing of the Bitcoin at that day’s NZD value. A taxable gain or loss is locked in even though you never touched fiat.
What is not taxed
Two points save people a lot of money and worry.
First, buying crypto with New Zealand dollars and holding it is not a taxable event. Tax only comes in when you dispose of it.
Second, for anyone using self-custody: transferring your own crypto from an exchange to your own wallet is not a disposal. You own the same assets. Only the location of the keys has changed. Moving coins to a hardware wallet doesn’t trigger tax, and it doesn’t hide you from the IRD either (more on that below). Our guide on how to transfer crypto from an exchange to a cold wallet in NZ covers the mechanics.
How much tax you’ll pay: the 2025–26 rates
Crypto profit is added to your other income and taxed at your marginal rate under New Zealand’s progressive brackets. There’s no special crypto rate and no tax-free threshold. Tax applies from the first dollar.
These are the brackets for the 2025–26 tax year (1 April 2025 to 31 March 2026):
| Taxable income (NZD) | Tax rate |
|---|---|
| $0 – $15,600 | 10.5% |
| $15,601 – $53,500 | 17.5% |
| $53,501 – $78,100 | 30% |
| $78,101 – $180,000 | 33% |
| $180,001+ | 39% |
Only the slice of income inside each band is taxed at that band’s rate. Your crypto gains sit on top of your salary, so they’re taxed at whichever bracket they push you into.
A quick worked example. Say you earn a $70,000 salary and make a $15,000 profit disposing of crypto during the year. That $15,000 sits on top of your salary. Part of it falls in the 30% band and, depending on your exact figures, part may reach the 33% band, so you’d owe roughly $4,500–$4,950 in tax on the crypto profit alone. The more you earn elsewhere, the higher the rate on your crypto gains.
Staking, mining and airdrops can be taxed twice
Passive crypto income works a little differently. When you receive staking rewards, mining rewards, or an airdrop you intend to sell, the IRD treats the tokens as income at their NZD market value on the day they arrive. That value also becomes your cost basis.
If those tokens then rise before you sell or swap them, the extra gain is taxable again on disposal. So rewards can be taxed at two points: once as income when received, and again as a gain if they appreciate. Record the NZD value at the moment each reward lands, because you’ll need it for both calculations.
What changed in 2026: the IRD can see your transactions
Some holders used to treat crypto as effectively invisible. That no longer works.
New Zealand has adopted the Crypto-Asset Reporting Framework (CARF), which took effect on 1 April 2026. Under it, New Zealand-based crypto service providers must collect transaction data on reportable users and pass it to the IRD. International information-sharing also gives the IRD visibility of what New Zealand tax residents do on overseas platforms. The IRD has said plainly that people are not anonymous on the blockchain and that it uses exchange data and analytics to match wallets to taxpayers.
Enforcement is already happening. The IRD has publicly stated it identified around 227,000 unique cryptoasset users in New Zealand, involved in roughly 7 million transactions worth about $7.8 billion, and it has been sending compliance letters to holders it believes have under-declared. If you’ve traded on a mainstream exchange, assume the IRD has your data or can ask for it.
Accurate self-reporting is now the starting point, not an optional extra.
How to report crypto on your tax return
Taxable income from crypto goes on your Individual income tax return (IR3). Before you can fill it in, you need the NZD value of each transaction and your net income or loss for the year.
In practice:
- Convert every transaction to NZD at its value on the date it happened. If you build one habit, make it this one.
- Track cost basis and proceeds for each disposal so you can work out the gain or loss.
- Offset losses where the assets were held on revenue account. Crypto losses can reduce crypto gains in the same year, and unused losses may carry forward.
- File your IR3 and pay by the deadline. For the 2025–26 year, individual returns are generally due by 7 July 2026 unless you have an extension through a tax agent.
- Keep your records for seven years. The IRD can ask you to back up every figure.
Crypto tax software such as Koinly or CryptoTaxCalculator can import your exchange history and handle most of the NZD conversion. It’s worth it once you have more than a handful of transactions.
Common crypto tax mistakes
- Assuming “no capital gains tax” means “no tax”. Crypto is taxed as income.
- Forgetting crypto-to-crypto swaps. Every swap is a disposal, even with no fiat involved.
- Not recording the NZD value at the time of each transaction. Rebuilding it later, especially after a big price move, is slow and easy to get wrong.
- Ignoring staking and airdrop income. It’s taxable when you receive it, not just when you sell.
- Thinking self-custody hides you. A hardware wallet secures your keys. It doesn’t remove your exchange history from the IRD’s view.
Moving to a cold wallet doesn’t change your tax position
We get asked this often enough that it deserves its own section. Moving your crypto into self-custody, meaning a hardware wallet you control, is not a taxable event, because you haven’t disposed of anything. You still own the same coins.
Self-custody changes your security and control, not your tax obligations. It protects you from exchange hacks, frozen withdrawals and insolvencies, which is why many NZ investors move long-term holdings off exchanges. It doesn’t reduce or hide what you owe. Your taxable events are your disposals, wherever your keys sit.

Frequently asked questions
Do I pay tax on crypto in New Zealand if I don’t cash out to NZD? Possibly, yes. You don’t need to convert to New Zealand dollars to trigger tax. Trading one coin for another, spending crypto, or buying an NFT with crypto are all disposals that can create a taxable gain.
Is there a capital gains tax on crypto in New Zealand? No. New Zealand has no general capital gains tax. Crypto profits are usually taxed as ordinary income instead, at your marginal rate of up to 39%, so in practice most gains are still taxable.
How does the IRD know about my crypto? It receives data from crypto exchanges in New Zealand and overseas, uses blockchain analytics, and has operated under the Crypto-Asset Reporting Framework since 1 April 2026. It has already identified hundreds of thousands of New Zealand crypto users.
Is moving crypto to a hardware wallet taxable? No. Transferring crypto between your own wallets, including to a cold wallet, is not a disposal and is not taxed.
Are staking rewards taxed in New Zealand? Yes. They are taxable income at their NZD value on the day you receive them, and any later increase in value is taxable again when you dispose of the tokens.
When is crypto tax due in New Zealand? Crypto income goes on your IR3 for the tax year running 1 April to 31 March. Individual returns for the 2025–26 year are generally due by 7 July 2026.
Can I offset crypto losses against my crypto gains? Often, yes. Losses on assets held on revenue account can offset gains in the same income year, and unused losses may be carried forward, subject to IRD rules.
Where to go from here
Start by pulling your exchange history for the tax year and putting an NZD value against every disposal. If the numbers are large or messy, hand them to an accountant before the IR3 deadline rather than after.
If you’re also moving long-term holdings off an exchange, see the Tangem Wallet range at Tangem NZ, the authorised New Zealand seller. It improves your security. Your tax bill stays the same.
