How to export your Coinbase transaction history
Coinbase stores your full trading history under Statements. You need the complete CSV, not just the current year, so the calculator can build accurate cost basis queues from your earliest purchases.
- Go to accounts.coinbase.com and sign in.
- Select Statements from the left sidebar.
- Under "Generate custom statement," select All assets and All transactions.
- Set the date range from account opening to today, not just the tax year.
- Choose CSV format and click Generate.
The export includes buys, sells, sends, receives, converts, staking rewards, Coinbase Earn, learning rewards, and Advanced Trade fills - all 35+ transaction types in a single file.
When are Coinbase profits taxable in NZ?
New Zealand has no general capital gains tax. But if you acquired crypto with the intention to dispose of it for profit, IRD treats any gain as taxable income. For most people actively trading on Coinbase, this threshold is met.
The key legal test is "acquired for the purpose of disposal." If you bought crypto on Coinbase planning to sell it when the price went up, the profit is taxable. This catches most exchange traders, especially those making regular buys and sells.
Taxable gains are added to your other income and taxed at your marginal rate, which ranges from 10.5% to 39% depending on your total income bracket.
- Taxable: Sells where intent to profit existed at purchase, regular trading, crypto-to-crypto swaps, spending crypto.
- May not be taxable: Long-term holds with genuinely no intent to sell at the time of purchase. IRD's view is that most crypto trading is taxable, so this exception is narrow and rarely applies to active exchange users.
- Staking rewards: Taxable as income at fair market value when received, regardless of intent. No ambiguity - income from property is always taxable.
- Filing deadline: 7 July for individual tax returns.
IRD has signaled increasing enforcement on crypto. Information-sharing agreements with overseas tax authorities mean Coinbase activity is not invisible to New Zealand tax officials.
What the calculator does
The calculator parses all 35+ Coinbase transaction types and applies FIFO matching across your complete history. For each disposal in your selected tax year, it calculates the cost basis, sale proceeds, and gain.
Since NZ taxation depends on intent, the report provides gain estimates that you can use with your tax advisor to determine which disposals are taxable. Not every trade may qualify, and the intent test is fact-specific to your situation.
All values are converted to NZD using historical daily exchange rates. The report includes a trading summary, income section for staking rewards, top assets by P&L, end-of-year holdings, and a complete transaction audit trail.
IRD and Coinbase
- No tax forms from Coinbase: Coinbase issues no IRD-compatible tax documents. New Zealand users must calculate and report all gains themselves.
- Intent matters: If you're actively trading on Coinbase - multiple buys and sells over weeks or months - IRD will likely consider your activity taxable. The more frequently you trade, the stronger the case for taxation.
- NZD conversion: Coinbase reports in USD. All values in your report are converted to NZD using historical exchange rates, which is what IRD expects.
- Staking on Coinbase: Staking rewards (ETH, SOL, ATOM) are taxable income when received, regardless of intent. Income from property is always taxable in NZ.
- Range estimates: Because NZ crypto tax depends on individual circumstances, our report shows gain estimates rather than definitive tax amounts. Discuss with your tax advisor.
