This page explains how the estimator approaches crypto CGT in Australia for the 2025-26 tax year. The focus is not on every possible token event. It is on the common investor pattern of buys, sells, and swaps that need to be translated into a taxable capital result.
In this estimator, a CGT event happens when you dispose of crypto. That includes selling for AUD and swapping one token for another. The output is a simplified estimate of capital gains, capital losses, discountable gains, and the part that may end up in taxable income for an Australian individual investor.
When you sell or swap crypto, the estimator matches the disposal against the oldest remaining parcels you entered for that asset first. That means a BTC disposal in February 2026 is measured against your earliest tracked BTC parcels, not whichever parcel would produce the best tax result.
Exchanging BTC for ETH is treated as a disposal of BTC at the AUD market value you enter, followed by a new ETH parcel created at that same value. If you do not know the AUD market value at the time of the swap, the CGT estimate will be weak even if the wallet activity itself is clear.
If the disposed parcel was held for more than 12 months, gains from that parcel are marked as discount eligible and reduced by 50% after capital losses are applied. The app surfaces the discountable part of the gain separately so you can see how much of the result depends on long-held parcels.
Suppose you buy BTC, hold it for over a year, then swap part of it into ETH. In this estimator, the BTC disposal may create a discount-eligible capital gain, while the acquired ETH becomes a fresh parcel with its own acquisition date and cost base. If you later sell that ETH, it is measured from the ETH parcel created on the swap date, not from the original BTC purchase date.
This is not a complete guide to every crypto tax issue. It does not attempt to cover every DeFi flow, NFT transaction, bridge, wrapped asset, or airdrop pattern. For this version, the relevant question is whether your event list is clean enough for a first CGT estimate in the app.
Yes. The outgoing asset is treated as a disposal at the AUD value entered, and the incoming asset becomes a new parcel.
A gain is marked as discount eligible only when the disposed parcel has been held for more than 12 months before disposal.
