Tax is a frequent topic of conversation surrounding cryptocurrency in New Zealand. Some common questions arising are; do we have to pay tax on money made in crypto? If we don’t pay what will happen? Isn’t it impossible for the IRD to find out what we have?

In short, yes you have to pay tax, if you don’t pay you may be fined or worse and everything is traceable on public ledger blockchains so if you are audited there is a possibility that your transactions and wallets can be traced with the correct information.


The IRD’s position on bitcoin is if someone buys bitcoin for the purpose of disposal, any gain or loss will be taxable income. This is the standard view of IRD as bitcoin does not have a strong show of benefit when being held aside from at the point of sale. This could change and is potentially contestable as there are shops accepting payment in BTC which shows a payment based use case not just a store of value. In this case it would fall under business income tax. Any situation in which BTC is not purchased for disposal there would need to be sufficient supporting evidence to show this.

Cryptocurrency is treated as property in New Zealand for tax purposes. Cryptocurrency received for payment of goods and services is business income and the taxable amount based off the value of the currency at the time. Tax must be paid on each trade made as each is a disposal of one currency for another. You must keep a record of all transactions for seven years just the same as any other financial information.

If you have not done your tax correctly do not worry you can contact the IRD and make a “voluntary disclosure”, we would recommend speaking to an accountant with cryptocurrency knowledge also. This is a lot better than having the IRD decide to force an audit.

All in all, disclosing and paying your taxes on cryptocurrency as the IRD require is the safest way forward. However as cryptocurrency regulation (even on a world wide level) is still very new, there may be some changes in the not too distant future so make sure to always keep up to date with current cryptocurrency related regulation.

The following is a question and answer segment from the IRD website pertaining to crypto tax in NZ, Date published: 28 Mar 2018


Is cryptocurrency treated as a foreign currency for tax purposes?

No. For tax purposes, cryptocurrency is property, not currency. This means foreign currency gain or loss provisions do not apply.


My business accepts cryptocurrency as payment for goods and services. Do I have to pay income tax on it?

Yes. Cryptocurrency received as payment for goods or services is business income, which is taxable. This is seen as a barter transaction and you’ll need to calculate the value of the cryptocurrency in New Zealand Dollars (NZD) at the time it’s received.

I have received payment in cryptocurrency. How do I calculate the NZD equivalent?

If your cryptocurrency receipt is not converted into New Zealand dollars (NZD) straight away by a cryptocurrency merchant processor, you’ll need to convert it to the NZD equivalent on the relevant date.

Conversion rates used must be from a reputable exchange with a reasonable trading volume.

For some ‘alt coins’ (cryptocurrency other than Bitcoin) it may be necessary to convert into US dollars, or any other fiat currency, and then convert into NZD. Rates can vary significantly between different exchanges and currencies. You must use a consistent exchange and conversion approach.


I purchased some cryptocurrency a few years ago. Will there be a capital or revenue (taxable) gain when I sell it?

It depends on your purpose for acquiring the cryptocurrency. Cryptocurrency is considered property for income tax purposes. Where you acquire cryptocurrency for the purpose of disposal (selling or exchanging it) the proceeds you make from selling it are taxable.

Bitcoin and similar cryptocurrencies generally don’t produce an income stream or provide any benefits, except when they’re sold or exchanged. This strongly suggests that cryptocurrencies are generally acquired with the purpose to sell or exchange them.

For income tax purposes, cryptocurrencies also have similar characteristics to gold bullion. We recently published a paper setting out when proceeds from the sale of gold bullion count as income, which may be of assistance.


Does tax apply only when I cash out cryptocurrency into NZD?

No. Any disposal that creates a realised gain or loss needs to be recorded at the time it occurs.

‘Disposal’ includes swapping one type of cryptocurrency for another or exchanging cryptocurrency for New Zealand dollars or another fiat currency such as US dollars or Euros.


Do I need to keep records of my cryptocurrency transactions?

Yes. You must keep sufficient records to be able to determine your income and deductions. Standard seven year record keeping requirements apply.

If you are using mobile and desktop wallets and exchanges you should have access to your transaction history (deposits, transactions and withdrawals) and be able to export this in a commonly used file format like CSV. You should also retain your bank statements and cryptocurrency wallet addresses for verification purposes.

Some overseas software providers are developing accounting and tax reporting products for cryptocurrency customers. These apps and websites enable manual CSV exchange imports, automatic API exchange imports, automatic API wallet imports and CSV and Excel imports from exchanges. If you use third party software, make sure transactions are accounted for in a way that meets New Zealand tax law.

I haven’t filed an income tax return before, what do I need to know?

I’ve sold cryptocurrency but haven’t followed the tax guidance here, what should I do?

If you haven’t got your tax right, let us know as soon as you can so it can be corrected. We call that making a voluntary disclosure.

Find out more about voluntary disclosures.


I’m planning an Initial Coin Offering. How can I get certainty about my tax treatment?

The tax implications of an Initial Coin Offering will depend on the unique features of the cryptocurrency being issued and how it’s distributed.

You may want to consider applying for a binding ruling to gain certainty about tax requirements.

Mining cryptocurrency


I’m a cryptocurrency miner. Do I have to pay tax on receipts from mining cryptocurrencies?

Yes. We consider cryptocurrency mining to generally be an activity aimed at making a profit, not a hobby. Any mining-related fees or rewards are taxable income.

A cryptocurrency miner is a person who validates cryptocurrency transactions and maintains the ledger. In exchange for this service, they receive cryptocurrency.


I am mining cryptocurrency as part of a pool. How do I account for mining fees and rewards that I receive as a share from the pool?

Mining income is derived when the pool periodically distributes each miner’s share.


What depreciation rate can I claim on cryptocurrency mining equipment?

See the Depreciation Rate Finder tool. ‘Computers’ is an ‘asset category’ for depreciation purposes.
