IRD Crypto Audit NZ: What Happens If IRD Reviews Your Crypto?

What Is an IRD Crypto Audit NZ Review?

An IRD crypto audit NZ review involves Inland Revenue examining relevant tax and financial records to determine whether a taxpayer has correctly reported their income and met their New Zealand tax obligations.

Crypto-assets are subject to New Zealand tax rules, and Inland Revenue has increased its focus on crypto-asset compliance. The introduction of the Crypto-Asset Reporting Framework (CARF) from 1 April 2026 also increases the amount of information available to tax authorities about relevant crypto-asset activity.

If Inland Revenue reviews your crypto transactions, you may need to provide records such as exchange statements, wallet information, transaction histories, bank records, transaction values and supporting tax calculations.

Crypto users should generally keep relevant records for at least seven years. If you receive an Inland Revenue request concerning crypto, it is important to understand exactly what is being requested and consider professional tax advice where the matter is complex.

What Is an IRD Crypto Audit in New Zealand?

An IRD crypto audit NZ review is not a separate type of tax that applies specifically to cryptocurrency. Instead, it is an Inland Revenue audit or review where crypto-asset activity forms part of the taxpayer’s financial and tax position.

Inland Revenue explains that an audit involves checking tax and business records to make sure the correct amount of tax has been paid.

For crypto investors, this may involve checking whether cryptocurrency transactions have been correctly identified, calculated and reported in their tax returns.

You can read the official Inland Revenue guidance on audits for more information about how the audit process works.

Why Is Inland Revenue Paying More Attention to Crypto?

Crypto-assets are not automatically outside New Zealand’s tax system.

Inland Revenue states that crypto-assets are treated as a form of property for tax purposes and that their tax treatment depends on the nature and circumstances of the activity.

In recent years, Inland Revenue has increased its access to crypto-asset information and has encouraged crypto investors to review their tax compliance.

Inland Revenue has also reported significant numbers of crypto users and transactions in New Zealand and has been using crypto-asset data to identify potential differences between reported income and transaction activity.

For taxpayers, this means that understanding IRD crypto audit NZ requirements and keeping accurate records is increasingly important.

Can IRD See Your Crypto Transactions?

Crypto Activity Is Becoming More Transparent

Yes. Inland Revenue has increasing access to information about crypto-asset activity.

The introduction of CARF New Zealand from 1 April 2026 means relevant Reporting Crypto-Asset Service Providers must collect and report specified information about reportable users and relevant transactions.

The information can include:

Name
Date of birth
Residential address
Tax residency
Tax identification number
Relevant crypto-asset transactions

Reportable transactions can include exchanges between crypto-assets and fiat currency, exchanges between different crypto-assets and certain transfers.

Read the official IRD CARF reporting requirements for the current information requirements.

What Is the Connection Between CARF and an IRD Crypto Audit?

CARF and an IRD crypto audit NZ review are not the same thing.

CARF is a reporting framework.

An IRD audit is a review of tax and financial records.

However, CARF can provide Inland Revenue with additional information that may assist with tax administration and compliance activities.

Inland Revenue explains that CARF information can be used to check whether crypto-asset income earned by New Zealand tax residents has been included in their income tax returns.

You can read the official IRD CARF overview for more information.

What Can Lead to an IRD Crypto Review?

There is no single factor that automatically means Inland Revenue will conduct an IRD crypto audit NZ review.

However, discrepancies or unusual patterns may result in questions about a taxpayer’s tax position.

Potential areas that could require clarification include:

Significant crypto trading activity
Frequent buying and selling
Crypto transactions that do not appear to have been reported
Differences between available information and tax returns
Missing transaction records
Large unexplained crypto transfers
Offshore crypto activity
Complex DeFi transactions
Staking or mining income
Inconsistent information across tax returns

These factors do not automatically trigger an audit. Each taxpayer’s circumstances are different.

What Happens During an IRD Crypto Audit?

If Inland Revenue selects you for an audit or review, it may request records that help establish how your tax position was calculated.

For someone with cryptocurrency activity, an IRD crypto audit NZ review could involve examining:

Crypto exchange transaction histories
Wallet records
Bank statements
Crypto transaction reports
Purchase and sale records
NZD valuations
Transaction fees
Previous tax returns
Tax calculations
Supporting documentation

The exact information requested will depend on the scope of the Inland Revenue review.

What Crypto Records Does IRD Require?

Keep Your Crypto Records for at Least Seven Years

Accurate record keeping is one of the most important parts of preparing for an IRD crypto audit NZ review.

Inland Revenue says crypto-asset users should keep records that support the position taken in their tax returns.

These records can include:

Type of crypto-asset
Date of each transaction
Type of transaction
Number of crypto units
Value of transactions in New Zealand dollars
Total crypto units held
Exchange records
Bank statements
Wallet addresses

IRD states that crypto-asset records generally need to be kept for at least seven years.

Read the official IRD crypto-asset record-keeping guidance for more information.

What If You Used Multiple Crypto Exchanges?

Using multiple exchanges and wallets can make cryptocurrency tax reporting more complicated.

For example, a taxpayer could move crypto between:

Exchange A → Wallet → Exchange B → DeFi platform → Exchange C

Each movement needs to be understood in context.

You may need to reconcile:

Purchases
Sales
Crypto-to-crypto swaps
Transfers
Fees
Deposits
Withdrawals
Wallet balances

If records are incomplete, calculating and supporting your tax position can become difficult during an IRD crypto audit NZ review.

Does an IRD Crypto Audit Include Overseas Exchanges?

Using an overseas crypto exchange does not automatically remove your New Zealand tax obligations.

New Zealand’s CARF framework also supports international exchange of relevant information between participating jurisdictions.

Inland Revenue can receive relevant information concerning New Zealand tax residents from participating overseas tax authorities.

Therefore, New Zealand tax residents should not assume that using an offshore exchange makes their crypto activity invisible to Inland Revenue.

The specific tax treatment and reporting requirements depend on your circumstances and the applicable rules.

What If You Did Not Declare Your Crypto Income?

If you discover that you have not correctly reported taxable crypto income, it is important not to ignore the issue.

Inland Revenue advises taxpayers to notify them when a tax return is incorrect so the error can be corrected.

Depending on the circumstances, a voluntary disclosure may also be relevant.

The appropriate approach can depend on:

The type of error
The tax year involved
The amount of income
Whether Inland Revenue has already contacted you
The circumstances surrounding the omission

Read Inland Revenue’s guidance on declaring crypto-asset income or losses before taking action.

Can IRD Review Previous Crypto Transactions?

Yes, an Inland Revenue review can involve records relating to previous tax periods.

This is one reason why maintaining crypto records for at least seven years is important.

Do not assume that a transaction is irrelevant simply because you no longer own the cryptocurrency.

If the transaction affects a tax return, you should retain the supporting records.

What Should You Do If IRD Contacts You About Crypto?

Step 1: Read the IRD Request Carefully

Identify exactly what Inland Revenue is asking for and whether the request relates to particular transactions, tax years or records.

Step 2: Gather Your Crypto Records

Collect exchange histories, wallet records, bank statements, transaction reports and previous tax calculations.

Step 3: Reconcile Your Transactions

Check whether your records support the figures previously included in your tax returns.

Step 4: Identify Potential Errors

If you identify missing transactions or potentially incorrect tax treatment, understand the issue before submitting additional information.

Step 5: Consider Professional Tax Advice

If the review involves significant transactions, multiple exchanges, offshore activity or previous tax errors, professional advice may help you understand your position and response.

How Can You Prepare for an IRD Crypto Audit?

The best time to prepare for an IRD crypto audit NZ review is before Inland Revenue contacts you.

Keep Complete Transaction Records

Download transaction histories from every exchange and maintain records for your wallets.

Record New Zealand Dollar Values

Maintain records showing the NZD value of relevant transactions.

Track Transfers Between Wallets

Keep documentation that explains where crypto came from and where it was transferred.

Save Exchange Statements

Download statements regularly instead of relying on an exchange to retain historical information indefinitely.

Keep Bank Records

Bank statements can help reconcile deposits, withdrawals and crypto purchases.

Retain Records for Seven Years

Maintain relevant crypto records for at least seven years in accordance with Inland Revenue’s record-keeping guidance.
