Many people assume cryptocurrency is untaxed or somehow invisible to Inland Revenue. Neither is true. In New Zealand, crypto-assets are treated as property for tax, not as money, and that simple fact drives how the tax works. If you buy and sell crypto, there is a good chance your gains are taxable income.
Inland Revenue can obtain information from exchanges and has made clear that crypto is within the tax system. The safe assumption is that your activity is visible and should be reported correctly.
The key question is why you acquired the crypto. If you bought it with the purpose of selling or exchanging it, the proceeds are generally taxable. Because crypto usually produces no income while held and is bought in the hope of selling higher, that purpose is common.
If you trade frequently and in an organised way, you may be treated as being in a business of trading, with the profits taxable as business income. The more regular and systematic the activity, the more likely this is.
| Activity | General Treatment |
|---|---|
| Mining | Rewards can be income when received |
| Staking | Rewards can be income |
| Airdrops | May be income depending on the circumstances |
| Later sale of those coins | Can be a further taxable disposal |
A taxable gain is broadly the New Zealand dollar value you received on disposal, less what you paid for the crypto and related costs. Because prices move and trades happen in crypto, you must convert each transaction to New Zealand dollars at the time it happened.
Good records are essential because exchanges may not keep your full history forever. Keep dates, amounts, the type of crypto, the New Zealand dollar value at the time, and the purpose. Many people use crypto tax software to pull transactions together.
If your crypto was held with a taxable purpose, a loss on disposal may be deductible against your crypto gains. As with rental losses and other rules, the treatment depends on your situation, so check the current rules.
Buying and selling crypto-assets is generally outside GST, so you do not usually charge or claim GST on the crypto itself. Income tax, not GST, is the main consideration for most people.
Crypto gains are commonly taxable in New Zealand. Treating them as invisible income risks penalties and interest.
Swapping one coin for another is a disposal of the first, even though you never touched dollars. Each swap can be a taxable event.
Reconstructing years of trades later is painful and error-prone. Record values in New Zealand dollars as you go.
Rewards can be income when received, separate from any later sale. Both events may need reporting.
For the wider tax picture, see our Progressive Tax System guide. Final word: crypto is treated as property in New Zealand, so gains made with a selling purpose are usually taxable income, including on crypto-to-crypto swaps, and mining and staking can be income too. Keep clean New Zealand dollar records and report honestly. This is general information, not tax advice; crypto tax can be complex, so consider a specialist.
