Record Keeping
You'll need to keep records of your cryptoasset transactions to support the position taken in your tax return. This includes:
- the type of cryptoasset
- date of the transaction
- type of transaction (for example, received or disposed of)
- number of units
- value of the transaction in New Zealand dollars
- total units of each cryptoasset held at the beginning and end of the year
- exchange records and bank statements
- wallet addresses.
You’ll need to keep these records for at least 7 years, even if you no longer have any cryptoassets.
