AU tax season FY25-26: what you need to know
Key dates, practical tips and FAQs for the FY25-26 Australian crypto tax season, so you can lodge an ATO-ready return before the 31 October deadline.
Confused about crypto tax in Australia? This guide has you covered. The FY25-26 tax year ended on 30 June 2026. Here’s how to get it done without the stress.
Key dates for FY25-26
- 30 June 2026: the tax year ended. Everything from 1 July 2025 to this date belongs in your FY25-26 return.
- 31 October 2026: the deadline to lodge your own return through myTax.
- Lodging through a registered tax agent can extend your deadline, but you generally need to be on their books before 31 October.
Tips for this tax season
- Start early. Reconciling a year of transactions takes longer than you think, especially across multiple wallets and exchanges.
- Get everything in one place. Transfers between your own wallets aren’t disposals, but if your records are incomplete they can look like one. Consolidate every exchange and wallet before you calculate.
- Review your categorisation. Staking rewards, airdrops and DeFi activity each have their own treatment. Make sure income is recorded as income and disposals as disposals.
- Check your inventory method. Different methods can produce different outcomes. Software lets you compare before you lodge.
- Use crypto tax software. Tools like Summ connect to your exchanges and wallets read-only, categorise every transaction, and produce an ATO-ready report you can lodge from or hand to your accountant.
FAQs
Do I owe tax if I never cashed out to AUD? Potentially, yes. Crypto-to-crypto swaps are CGT events even if you never touched fiat.
I only made losses, do I still need to report? Yes. Reporting losses lets you offset current gains and carry the rest forward to future years.
What records do I need? Dates, AUD values, transaction types and counterparties for every transaction. Software keeps these automatically.
