From 1 April 2026, the way Inland Revenue sees your crypto activity changes permanently. The Crypto-Asset Reporting Framework (CARF) is now NZ law, and the days of assuming an offshore exchange or a quiet wallet will fly under the radar are effectively over. Here is what CARF actually changes, who it applies to, and what NZ crypto investors should be doing now.

What is CARF?

CARF is a global tax transparency standard developed by the OECD. It works much like the Common Reporting Standard (CRS) does for traditional financial accounts, but for crypto. New Zealand adopted CARF into law in March 2025, and the first reporting period begins on 1 April 2026.

Under CARF, Reporting Crypto-Asset Service Providers (RCASPs) are required to collect detailed user and transaction information and pass it to the IRD on an annual basis. The IRD then automatically exchanges that data with 48 other participating tax authorities globally.

Who counts as a Reporting Crypto-Asset Service Provider?

An RCASP is broadly defined and captures most of the platforms NZ users actually interact with, including:

• Centralised cryptocurrency exchanges (NZ-based and offshore)

• Crypto brokers and over-the-counter desks

• Operators of crypto trading platforms

• Certain wallet operators where they exchange or transfer assets on behalf of users

• NFT marketplaces facilitating transactions

The combination of NZ's domestic CARF rules and international data exchange means that even if you trade on an exchange registered in another participating jurisdiction, that platform is reporting your activity to its local tax authority, which then shares it with the IRD.

What information gets reported?

RCASPs are required to collect and report:

• User identity details: name, address, date of birth, and tax residency

• Tax identification number for each jurisdiction of residence

• Aggregate transaction totals for the year, broken down by crypto asset

• Transfers between wallets, including transfers off-platform

• High-value retail transactions, including crypto-for-goods purchases above a defined threshold

This is significantly more granular than what the IRD has previously been able to access. Aggregate exchange totals make it straightforward for IRD analysts to compare reported income on your IR3 against what your exchanges actually saw you do.

Key dates

• 1 April 2026: First CARF reporting period begins

• 31 March 2027: First reporting period ends

• 30 June 2027: First annual CARF reports due to the IRD from RCASPs

• From late 2027 onward: First international data exchanges between IRD and other CARF jurisdictions

What this means if you have unreported crypto from prior years

CARF only applies to transactions from 1 April 2026 onward, but the data RCASPs collect to identify their reportable users includes historical account information. In practice, that means the IRD will receive enough context to look at what you might have done before the framework kicked in.

If you have unreported crypto activity from previous tax years, the time to address it is now. The IRD's voluntary disclosure regime treats early, proactive disclosure significantly more favourably than disclosure made after an audit notice has landed. The reduction in shortfall penalties for pre-notification disclosure can be material.

What you should do before 1 April 2026

1. Reconcile your full crypto history. Pull every exchange statement, wallet history, and DeFi transaction across every platform you have ever used. Tools like Summ aggregate all of this automatically.

2. Confirm your tax residency status with your exchanges. RCASPs need accurate residency data to file correctly. Mismatched information is one of the easier ways to get flagged for review.

3. Address any unreported income or disposals from prior years. Speak to a tax adviser about voluntary disclosure if there are amounts you have not previously declared.

4. Set up a record-keeping system that survives the first reporting cycle. When the IRD starts cross-referencing CARF data against IR3 returns, your records need to match what your exchanges report.

How Summ helps NZ users prepare for CARF

Summ pulls every transaction across centralised exchanges, on-chain wallets, and DeFi protocols into a single reconciled ledger, then produces an IRD-ready report calculated under NZ rules. That makes the IR3 reporting side of the equation match what your RCASPs are sending to the IRD, removing the most common source of CARF-driven audit risk.
