Crypto Tax in New Zealand 2026 - Complete Guide
Yes, crypto is taxable in New Zealand. This guide explains taxable events, marginal tax rates, records, IR3 returns, CARF reporting, DeFi, NFTs and common crypto tax questions.
Updated April 2026
Yes, crypto is taxable in New Zealand. The IRD treats cryptocurrency as property - not currency - which means every time you sell, trade, or spend it, you may owe income tax on any gain. There is no separate capital gains tax in NZ. Your crypto profits are added to your total income and taxed at your marginal rate, up to 39%.
How IRD treats crypto
The IRD treats cryptoassets as property for tax purposes. In many cases, crypto is acquired with the intention of disposal - which can make gains taxable income under New Zealand income tax rules.
This means:
- Crypto profits are income, not capital gains.
- Losses can generally be offset if a profit from the same activity would have been taxable.
- Every transaction must be converted to NZD at the time it occurred.
- There is no minimum threshold - small gains are still technically taxable.
What triggers a taxable event
| Transaction | Taxable? |
|---|---|
| Selling crypto for NZD | Yes |
| Trading one crypto for another | Yes |
| Using crypto to buy goods or services | Yes |
| Mining rewards received | Yes |
| Staking rewards received | Yes |
| Receiving crypto as a gift | No - but taxable when you later sell if the later gain is taxable |
| Buying crypto with NZD | No |
| Transferring between your own wallets | No |
Example: Ben buys $5,000 of Ethereum. Six months later he trades it for Bitcoin when the Ethereum is worth $8,000. He never touched NZD - but the $3,000 gain is still taxable income in the year the swap happened.
Example: Sarah uses $2,000 worth of Bitcoin to pay for a laptop. That counts as a disposal. If she originally paid $800 for that Bitcoin, the $1,200 gain is taxable.
How to calculate your gain or loss
Your taxable gain is simply: sale price minus cost price, both in NZD at the time of each transaction.
| Amount | NZD |
|---|---|
| Purchase price, cost basis | $10,000 |
| Sale price | $25,000 |
| Taxable gain | $15,000 |
If you sell at a loss, that loss can generally be offset against other crypto gains or taxable income if a profit from the same activity would have been taxable.
Transaction fees paid to acquire crypto can be added to your cost basis, which reduces your gain.
If you have hundreds of transactions, crypto tax software like Koinly or CoinTracker can calculate your NZD gain/loss automatically by syncing with your exchange accounts.
Which tax rate applies
There is no flat crypto tax rate. Your gain is added on top of all your other income for the year and taxed at your marginal rate.
| Total income, including crypto gains | Tax rate on that portion |
|---|---|
| Up to $15,600 | 10.5% |
| $15,601 to $53,500 | 17.5% |
| $53,501 to $78,100 | 30% |
| $78,101 to $180,000 | 33% |
| Over $180,000 | 39% |
Example: Tom earns $55,000 from his job and made $20,000 profit from crypto this year. His total income is $75,000. The crypto gains sitting between $53,501 and $75,000 are taxed at 30%.

What records you need to keep
IRD requires you to keep records for at least 7 years. For every transaction you need:
- Date of transaction.
- Amount of crypto bought or sold.
- NZD value at the time of the transaction.
- Name of the exchange or platform used.
- Transaction fees paid.
- What the transaction was for.
The easiest way to do this is to export transaction history from every exchange you use regularly and store it somewhere safe.
How to declare crypto income
Crypto income is declared in your IR3 individual tax return, filed through myIR. You report it as other income in the income section.
If you have a tax agent, give them your transaction records and gain/loss summary. If you are filing yourself, calculate your total net gain for the tax year, 1 April to 31 March, and enter it in myIR.
The IRD tax year runs 1 April to 31 March. Returns are due by 7 July unless you have a tax agent.
What happens if you do not declare
From 1 April 2026, New Zealand adopted the OECD Crypto-Asset Reporting Framework (CARF). This requires New Zealand-based reporting crypto-asset service providers to collect user information and report relevant transaction data to the IRD. The first reporting period is 1 April 2026 to 31 March 2027, with the first report due by 30 June 2027.
In plain English: the IRD can cross-reference what exchanges and service providers report against what you declare. If an exchange reports you sold $50,000 of Bitcoin and your tax return shows nothing, expect questions.
Penalties for not declaring can include:
- Shortfall penalties for not taking reasonable care.
- Higher penalties where evasion is involved.
- No standard 4-year reassessment limit in cases involving fraud.
DeFi, NFTs, and airdrops
IRD has not issued specific guidance on every DeFi scenario, but based on existing rules:
| Activity | How IRD may treat it |
|---|---|
| DeFi lending/yield | Income tax on rewards received |
| DeFi swaps | Taxable disposal - same as crypto-to-crypto trades |
| NFT sale | Taxable gain if acquired with intent to sell or as part of a taxable activity |
| Airdrops | May be taxable income depending on the facts |
| Hard forks | May be taxable income depending on the facts |
These areas are less clear-cut than straightforward trading. If your DeFi activity is significant, getting advice from a tax professional who specialises in crypto is worth it.
FAQs
Does IRD know about my crypto?
Increasingly yes. From April 2026, New Zealand reporting crypto-asset service providers must collect and report user and transaction information to IRD under CARF, with first reports due in 2027. IRD can also use other information sources when checking tax positions.
Do I pay tax if I just hold crypto and never sell?
No. Simply holding crypto is not usually a taxable event. Tax generally applies when you dispose of it - sell, trade, exchange, spend, or gift it.
Can I offset crypto losses against my salary?
Generally yes, if a profit from the same crypto activity would have been taxable. Keep records to support any loss claims.
What if I made losses this year?
Losses can reduce your taxable income if they relate to taxable crypto activity. If your total crypto activity for the year was a net loss, you may be able to claim that against other income. Keep full records of every transaction.
Is there a minimum amount before crypto is taxable?
No. IRD does not publish a general de minimis threshold for crypto gains. Technically all taxable gains should be included.
What about crypto in a company structure?
Companies pay a flat 28% tax rate, which is lower than the top personal rate of 39%. However, IRD monitors structures that are used mainly to reduce tax. Get professional advice before structuring crypto activity this way.
When is the tax return deadline?
7 July for most individuals filing an IR3. If you use a tax agent, the deadline may be extended.
