New Zealand famously has no general capital gains tax so it’s easy to assume the profit on your Bitcoin is yours to keep. It usually isn’t. Crypto Taxed in New Zealand works differently from almost every other investment, and 2026 is the year that difference stopped being theoretical: Inland Revenue (IRD) now receives transaction data straight from exchanges, and the global Crypto-Asset Reporting Framework has come into force.
This guide explains exactly how the IRD taxes cryptoassets, what actually counts as a taxable event (and what doesn’t), the rates you’ll pay, and how the new reporting rules change things. No dense legislation — just what a Kiwi holder needs to stay compliant and avoid 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.
The short answer: crypto is taxed as income, not capital gains
Here’s the core idea 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 a form of property, not money and not a financial arrangement. When you make a profit disposing of that property, the profit is treated as ordinary income and taxed at your normal marginal rate.
In practice, the IRD’s position is that most people buy crypto with the intention of eventually selling or exchanging it — and where that intention exists, any profit on disposal is taxable income. It’s a broad test, and the IRD applies it broadly. If you bought crypto hoping it would go up in value, assume your gains are taxable.
There’s a narrow exception for assets genuinely acquired for a long-term, non-sale purpose, but the IRD sets a high bar for that argument, so most everyday investors should treat disposals as taxable.
What counts as a taxable event in New Zealand?
This is where a lot of Kiwis get caught out. A “disposal” isn’t just cashing out to New Zealand dollars. You don’t have to see a single dollar hit your bank account to trigger a tax liability.
| 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 |
The crypto-to-crypto trap surprises the most people. Swapping Bitcoin for Ethereum inside an exchange feels like shuffling assets around, but the IRD treats it as disposing of the Bitcoin at its NZD value that day — so a taxable gain or loss crystallises even though you never touched fiat.
What is not taxed
Two points are worth emphasising because they save people money and stress.
First, buying crypto with New Zealand dollars and holding it is not a taxable event. Tax only enters the picture when you dispose of it.
Second, and this matters if you use self-custody: transferring your own crypto from an exchange to your own wallet is not a disposal. You still own the same assets — you’ve just changed where the keys live. Moving coins to a hardware wallet doesn’t trigger tax and doesn’t hide you from the IRD either (more on that below). If you’re weighing up self-custody, our guide on how to transfer crypto from an exchange to a cold wallet in NZ walks through the mechanics.
How much tax will you pay? The 2025–26 rates
Because crypto profit is added to your other income, it’s taxed at your marginal rate under New Zealand’s progressive brackets. There’s no separate crypto rate and no tax-free threshold — tax applies from the first dollar of income.
Here 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% |
Because the system is progressive, only the slice of income within each band is taxed at that band’s rate — your crypto gains stack on top of your salary and are taxed at whatever 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 higher your other income, the higher the rate your crypto gains attract.
Staking, mining, and airdrops: taxed twice?
Passive crypto income has its own wrinkle. 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 you receive them. That value also becomes your cost basis.
Here’s the catch: if those tokens then rise in value before you sell or swap them, the extra gain is taxable again on disposal. So staking rewards can effectively be taxed at two points — once as income when received, and again as a gain if they appreciate before you dispose of them. Keep a dated record of the NZD value at the moment each reward lands, because you’ll need it for both calculations.
What changed in 2026: the IRD can now see your transactions
For years, some holders assumed crypto was effectively invisible. That era is over.
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, with that information flowing to the IRD (and, through international information-sharing, giving the IRD visibility of transactions Kiwi tax residents make on overseas platforms too). The IRD has been clear that people are not anonymous on the blockchain and that it uses exchange data and analytics to match wallets to taxpayers.
The scale of enforcement is real. 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 either has your data or can request it.
The takeaway is simple: accurate self-reporting is no longer optional insurance — it’s the baseline.
How to report crypto on your tax return
If you have taxable income from crypto activity, you report it on your Individual income tax return (IR3). Before you can enter your figures, you need to work out the NZD value of each transaction and calculate your net income or loss for the year.
The practical steps:
- Convert every transaction to NZD at its value on the date it happened. This is the single most important habit.
- Track cost basis and proceeds for each disposal so you can calculate 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 substantiate every figure.
Crypto tax software such as Koinly or CryptoTaxCalculator can pull your exchange history and do most of the NZD conversion automatically — worthwhile if you have more than a handful of transactions.
Common crypto tax mistakes Kiwis make
- Assuming “no capital gains tax” means “no tax.” It doesn’t. Crypto is taxed as income.
- Forgetting crypto-to-crypto swaps. Every swap is a disposal, even without fiat.
- Not recording the NZD value at the time of each transaction. Reconstructing this later, especially after a price move, is painful and error-prone.
- Ignoring staking and airdrop income. These are taxable on receipt, not just on sale.
- Believing self-custody hides you. A hardware wallet secures your keys; it doesn’t erase your exchange history from the IRD’s view.
Does moving to a cold wallet change your tax position?
This is worth its own answer because it’s so commonly misunderstood. Moving your crypto into self-custody — a hardware wallet you control — is not a taxable event, because you haven’t disposed of anything. You still own the same coins.
What self-custody changes is security and control, not your tax obligations. It protects you from exchange hacks, freezes, and insolvencies, and it’s why many NZ investors move long-term holdings off exchanges. But 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? Yes, potentially. 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. But crypto profits are usually taxed as ordinary income instead, at your marginal rate of up to 39%, so the practical effect is that most gains are still taxable.
How does the IRD know about my crypto? The IRD receives data from crypto exchanges here and overseas, uses blockchain analytics, and now operates under the Crypto-Asset Reporting Framework from 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 your own 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. Staking rewards 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 is reported 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.
The bottom line
Crypto tax in New Zealand comes down to one principle: there’s no capital gains tax, but the IRD treats crypto as property and taxes the profit as income — and as of 2026, it can see far more of your activity than ever before. Know what counts as a disposal, record the NZD value of every transaction, and file your IR3 accurately. Self-custody is still one of the smartest moves you can make to protect your assets from exchange risk — just remember it changes your security, not your tax bill.
