CRYPTO TAX IN NZ: WHAT’S TAXABLE AND HOW TO REPORT IT

Crypto Tax in NZ: What’s taxable? Basically, almost everything you do. Whether you’re trading Bitcoin, minting NFTs, or staking tokens, chances are that it’s taxable. But there are nuances. Let’s explore! This guide was updated in October 2026. It breaks down how crypto is taxed in New Zealand, what the Inland Revenue Department (IRD) expects from you, and how to stay compliant while making the most of your digital assets. But before we go any further, let’s give you an overview:

30-Second Read

• IRD applies the normal income tax rules to crypto. The key question is why you acquired it.
• If your main purpose when you acquired crypto was to sell or exchange it, your profit is taxable income.
• Holding for years does not change your purpose. IRD says a “long-term investment” usually still means a purpose of disposal.
• Swapping one crypto for another counts as a disposal and an acquisition.
• Rewards, such as staking income, can be taxable when you receive them. Their value on that day becomes your cost when you later sell.
• Your income from a sale is the sale price, minus the purchase cost, minus transaction fees. You work out cost using FIFO or WAC.
• Losses offset your other crypto profits first, then your other income. To claim a loss, you must show that a profit would have been taxable.
• Unrealised gains are not taxed.
• Keep your records for at least seven years. Attach your calculation report to your return.

 

 

Is Crypto Taxable in New Zealand?

Absolutely. The IRD treats cryptocurrency as property, not currency. That means any profits you make from buying, selling, trading, or earning crypto are generally subject to Income Tax. Unlike some countries, New Zealand doesn’t have a separate Capital Gains Tax. Instead, gains from crypto are taxed as income—just like your salary or business profits.

How the IRD Views Crypto Transactions

The IRD has made it clear: if you’re making money from crypto, they want a slice. Here’s how they break it down:

Taxable Events Include:

• Selling crypto for NZD or other fiat currencies
• Trading one crypto for another (yes, even swapping Bitcoin for Ethereum)
• Using crypto to buy goods or services
• Lending crypto (if you lose beneficial ownership or receive a token in return)

These are all considered disposals, and if you make a profit, it’s taxable.

Earning Crypto? That’s Income Too

Some crypto activities are taxed as income when you acquire the asset:

• Mining rewards
• Staking rewards
• Referral bonuses

If you’re earning crypto in any way, it’s likely taxable the moment it hits your wallet.

Exceptions

Certain crypto activities may not be taxable in all situations. These two are dependent on purpose at acquisition:

• Airdrops
• Hard-Forks

What About Losses?

Good news: if you’ve made losses on your crypto investments, you can offset them against gains. This can reduce your overall tax bill. But you’ll need to keep solid records to prove it.

---

Can the IRD Track Crypto?

Yes, and they’re getting better at it.  The IRD can request data from centralized exchanges, including customer details and transaction histories. If you’ve used platforms like Binance(opens in new tab), Coinbase, or Swyftx(opens in new tab), chances are the IRD already knows about your activity.

While non-custodial wallets (like MetaMask(opens in new tab) or Ledger) offer more privacy, they don’t make you invisible. If you’ve moved assets between wallets or exchanges, those transactions can still be traced.

Crypto Tax Rates in New Zealand

Your crypto gains are taxed at your personal income tax rate. Here’s a quick look at the current brackets for the 2025–2026 tax year:

So if you’re making serious gains, expect a serious tax bill.

How to Calculate Your Crypto Tax

This is where things get tricky. You’ll need to track:

• Every transaction (buy, sell, trade, earn)
• The value of each asset at the time of the transaction
• Your cost basis (what you paid for the asset)
• Any fees paid

The IRD recommends using either:

• FIFO (First In, First Out): The oldest assets are sold first.
• WAC (Weighted Average Cost): Averages the cost of all assets.

Both methods are accepted, but consistency is key. Pick one and stick with it.

Worked Example 1: Mele Sells a Coin for a Profit and Another at a Loss

Mele works full time on $90,000 a year. In March, she buys one unit of crypto A for $1,000. In June, she buys a second unit for $2,000. She calls both purchases a long-term investment. Neither coin pays her anything while she holds it.

IRD looks at her purpose when she bought. The coins give her no income, so the only benefit comes from selling or exchanging them. A “long-term investment” label does not change that. Mele’s profit is therefore taxable when she sells.

In December, she sells one unit of crypto A for $2,600 and pays a $26 fee. Her income depends on her cost method:

• FIFO (first in, first out): The first unit she bought is the first one sold, so her cost is $1,000. Her income is $2,600 − $1,000 − $26 = $1,574.
• WAC (weighted average cost): Her average cost is ($1,000 + $2,000) ÷ 2 = $1,500. Her income is $2,600 − $1,500 − $26 = $1,074.

IRD accepts either method. Mele picks one and applies it to all her disposals.

She also sells crypto B at a $400 loss. She bought it for the same purpose, so a profit would have been taxable. That lets her claim the loss. It offsets her other crypto profits first, then her other income.

• With FIFO, her net crypto income is $1,574 − $400 = $1,174.
• With WAC, her net crypto income is $1,074 − $400 = $674.

Suppose her salary puts her in the 33% band. Before any levies, that adds about $387 (FIFO) or $222 (WAC) to her tax bill. Mele pays nothing on the unit she still holds, because unrealised gains are not taxable.

She files an IR3, attaches the report from her crypto tax tool, and puts the net figure in the “other income” box.

Worked Example 2: Tomás Stakes His Coins While He Waits

Tomás buys $5,000 of crypto D on a New Zealand exchange. He reads the price history and plans to sell when the price peaks. While he waits, he stakes the coins on the exchange to earn rewards. He saves his research notes.

IRD says what you say about your purpose must match what you do. Tomás plans to sell at a peak, and his actions support that. He therefore has a purpose of disposal.

During the year, he receives staking rewards. They are worth $300 in New Zealand dollars on the days he receives them. He records each reward at its NZD value that day and declares the $300 as income.

Later, he sells everything, including the rewards, for $9,000. He pays a $50 fee. His cost is the $5,000 he paid, plus the $300 of rewards he already declared. His income on the sale is $9,000 − $5,300 − $50 = $3,650.

In total, Tomás declares $300 + $3,650 = $3,950 of crypto income. Adding the rewards to his cost stops him from paying tax on the $300 twice.

Common Mistakes to Avoid

Crypto tax is still a grey area for many investors. Here are some pitfalls to watch out for:

1. Ignoring Crypto Trades

Even if you didn’t cash out to NZD, trading crypto is still taxable.

2. Forgetting About Airdrops and Rewards

If you received tokens for free, they might still be taxable—especially if it’s part of a business activity.

3. Not Reporting Losses (or Theft)

Losses and theft can reduce your tax bill, but only if you report them. There are specific rules around the value of what you can claim, so get good advice. And we don’t mean off some random self-proclaimed expert on TikTok.

4. Mixing Personal and Business Crypto

If you’re running a crypto-related business, keep those transactions separate from personal ones.

5. Falling for Scams

If it sounds too good to be true, it probably is. See this article and this guidance(opens in new tab)

What If You’re a Crypto Business?

If you’re mining, staking, or trading crypto as a business, the rules are stricter. You’ll need to:

• Register for GST (if applicable)
• Keep detailed records of income and expenses
• File regular business tax returns

Talk to a crypto-savvy accountant to make sure you’re ticking all the boxes.

Record-Keeping: Your Best Defence

The IRD expects you to keep records for at least seven years. That includes:

• Transaction dates
• Asset types
• Amounts
• NZD value at the time
• Fees paid
• Wallet addresses
• Exchange details

If you’re ever audited, these records will be your lifeline.

Checklist: Your Crypto Tax Return

Before you transact

• ✅ Write down why you are buying, and keep any research or notes
• ✅ Download your exchange histories regularly, because exchanges may keep records only for a short time

Working out your income

• ✅ List every wallet and platform, in New Zealand and overseas
• ✅ Classify each transaction correctly. A transfer between your own wallets is not a disposal
• ✅ Record each crypto-to-crypto swap as both a disposal and an acquisition
• ✅ Review DeFi transactions one contract at a time. Losing possession of your crypto is a disposal
• ✅ Convert every transaction to New Zealand dollars at its date
• ✅ Choose FIFO or WAC, and apply your choice consistently
• ✅ Calculate income as sale price − purchase cost − transaction fees
• ✅ Declare reward income at its NZD value when you receive it
• ✅ Reconcile your holdings as at 31 March each year
• ✅ Check that any loss relates to crypto where a profit would have been taxable

Filing and records

• ✅ File an IR3 and put your net crypto income or loss in the “other income” box if it does not fit another box
• ✅ Attach the report with your calculation
• ✅ Keep your records for at least seven years. They include the asset type, date, transaction type, units, NZD value, year-start and year-end holdings, exchange records, bank statements and wallet addresses
• ✅ Keep GST records if your mining or staking activity is GST-registered

What Happens If You Don’t Report?

Failing to report crypto income can lead to:

• Penalties
• Interest charges
• Audits
• Legal action

The IRD is actively cracking down on crypto tax evasion. It’s not worth the risk.

A related matter is that your bank may contact you as part of the Crypto-Asset Reporting Framework (CARF).(opens in new tab)) See our article about FATCA/CRS for more info on what these letters mean.

How to File Your Crypto Tax Return

You’ll file your crypto income as part of your annual tax return via myIR(opens in new tab). Here’s how:

1. Calculate your total crypto income and gains
2. Include it under “Other Income”
3. Attach supporting documentation if needed
4. Submit by 7 July (or later if using a tax agent)

If you’re unsure, work with a tax professional who understands crypto e.g. Epsomtax.com Limited

---

Crypto Tax and Trusts

If you hold crypto in a trust, things get more complex. You’ll need to:

• Ensure the trust deed allows crypto investments
• Track transactions separately from personal ones
• File trust tax returns

Note that crypto bought in personal names could be held “in trust” for a trust, but you will need the documentation to back this up. Talk to your lawyer. Trusts can offer asset protection and tax planning benefits, but they require careful management.

Planning Ahead: Tax Strategies for Crypto Investors

Want to reduce your tax bill legally? Here are some smart strategies:

1. Tax Loss Harvesting

Sell underperforming assets before the tax year ends to offset gains.

2. Long-Term Holding

If you’re not actively trading, holding assets may reduce taxable events.

3. Use FIFO or WAC Strategically

Choose the method that gives you the best outcome—just be consistent.

4. Work With a Specialist

A crypto accountant can help you structure your portfolio for tax efficiency.

Final Thoughts: Stay Ahead of the Curve

Crypto tax in New Zealand turns on your purpose when you acquire the asset. If you acquire crypto to sell or exchange it, your profit is taxable, even if you hold it for years. Swaps count as disposals. Rewards can be income when you receive them, and their value becomes your cost.

Calculate your income as the sale price, less cost and fees, using FIFO or WAC. Losses offset other crypto profits and then other income, but only if a profit would have been taxable. Unrealised gains are not taxed.

Good records make all of this easier. Keep every transaction for seven years, attach your calculation to your return, and ask for help before you file if your situation is complex.
