New Zealand Crypto Tax Deadline 2025
The IRD tax return deadline for the 2024/25 income year is 7 July 2025 for most individuals filing directly. New Zealand does not have a general capital gains tax - but if you bought crypto with the purpose or intention of selling it, profits are taxable as ordinary income. For the 2025/26 income year, the self-filing deadline will be 7 July 2026.

New Zealand's tax framework for crypto differs from most countries because there is no general capital gains tax. Instead, the taxability of crypto gains depends on your intention at the time you acquired the asset.
If you bought crypto with the purpose or intention of selling or exchanging it at a profit, any gain is taxable as ordinary income under the "revenue account" rules. IRD's view is that most crypto trading is taxable, so the exception for non-taxable holds is narrow - it applies only where there is genuine evidence that an asset was acquired for a purpose other than disposal.
Taxable gains are added to your other income (salary, business income, rental income) and taxed at your marginal rate: 10.5%, 17.5%, 30%, 33%, or 39% depending on your total income.
Key dates for 2024/25
New Zealand's income year runs April to March, with filing due in July of the same calendar year the year ends.
- 1 April 2024: 2024/25 income year begins.
- 31 March 2025: 2024/25 income year ends. All crypto disposals up to this date are reportable for 2024/25.
- 7 July 2025: Self-filing deadline via myIR. This deadline has now passed.
- 31 March 2026: Tax agent extended deadline. Registered tax agents operate under a filing schedule that typically extends to March 2026. This deadline has also now passed.
- 7 July 2026: Self-filing deadline for the 2025/26 income year (1 April 2025 to 31 March 2026).
What you need to file your return
New Zealand crypto reporting does not use a separate capital gains schedule. Trading gains are reported as income in your IR3 individual tax return.
- Complete exchange CSV exports. Download your full transaction history from Coinbase, Binance, Kraken, and any NZD exchanges you used. You need every disposal during the income year to calculate total taxable gains.
- Cost records for each asset sold. Your taxable gain is the sale price minus the original cost. Full acquisition history determines the correct cost figure.
- Staking and airdrop income records. Staking rewards are generally taxable as income at the NZD market value when received. These are separate from trading gains but also reported as income.
- IR3 individual tax return. Report crypto trading income in the "other income" section. If your crypto activity is substantial or complex, working with a tax agent familiar with IRD's crypto guidance is advisable.
How to calculate your crypto taxes
NZ crypto tax is calculated as income rather than capital gains. The process is straightforward once you have complete records.
- Export your full transaction history. Download complete CSVs from each exchange you used during the 2024/25 income year (1 April 2024 to 31 March 2025).
- Upload to DYOR.tax and select New Zealand. The engine calculates your taxable trading income for each asset, using your acquisition costs to determine the gain on each disposal.
- Review your free preview. See your total taxable income from crypto, broken down by asset, with staking and other income shown separately. All values in NZD.
- Download the full PDF report. It includes a complete disposal schedule and income summary ready to enter into your IR3. Share with your tax agent or enter the figures directly in myIR.
Penalties for late filing in New Zealand
IRD applies penalties and use of money interest when returns are filed late or tax is paid late.
- Late filing penalty: IRD can charge a late filing penalty for returns not filed on time. The amount depends on the amount of tax owed - penalties range from $50 for smaller tax debts up to $500 or more for larger liabilities.
- Use of money interest (UOMI): IRD charges interest on overdue tax from the day after the due date. The interest rate is set by IRD and compounds daily on the outstanding amount.
- Shortfall penalties: If IRD finds you understated your income (e.g., omitted crypto gains), shortfall penalties apply on top of the tax owed. Voluntary disclosure before IRD contact significantly reduces these penalties.
- File now if overdue. Both the July 2025 and March 2026 deadlines have passed. If you have an outstanding 2024/25 return, filing it now stops the clock on ongoing late filing penalties and demonstrates good faith to IRD.
Common reasons NZ crypto filers miss the deadline
- Assuming "no CGT" means no tax on crypto. New Zealand has no capital gains tax, but most crypto trading gains are taxable as ordinary income under the intention-to-sell test. The two are different things.
- Thinking only NZD withdrawals are taxable events. Every disposal - crypto-to-crypto trades, DeFi swaps, spending crypto - is a potential taxable event, not just selling to NZD.
- Not reporting staking rewards. Staking income is generally taxable when received, regardless of whether you later sold the tokens. Many filers only think about disposals and miss the income component.
- Relying on exchanges to issue tax summaries. Unlike some jurisdictions, there is no standardised tax reporting from NZ or overseas exchanges. You are responsible for calculating and reporting your own income from crypto.
