Stablecoin tax in Australia: pegged does not mean tax-free
Many investors move into stablecoins believing it is a tax-neutral "safe harbour" during volatile markets. In Australia, swapping to a stablecoin is a taxable disposal, and holding one can still generate gains due to USD/AUD movements.
Stablecoins are CGT assets despite being pegged
The ATO treats USDT, USDC, DAI, and similar stablecoins as CGT assets. Their peg to the US dollar does not remove them from the CGT framework. Every disposal of a stablecoin — selling for AUD or swapping for another asset — is a CGT event.
Swapping crypto to a stablecoin is a disposal
Moving from BTC, ETH, or any other cryptocurrency into USDT or USDC is not a tax-neutral action. The crypto you disposed of triggers a CGT event at its AUD market value at the time of the swap. Many investors who moved to stablecoins during market downturns have crystallised capital losses without realising it.
FX movements can create gains even on stablecoins
Because stablecoins are pegged to USD, their AUD value fluctuates with the USD/AUD exchange rate. If you acquired USDT when the AUD was strong and later sold when the AUD had weakened, the stablecoin appreciated in AUD terms — creating a taxable capital gain even though the USD value was unchanged.
What this estimator covers
This estimator handles stablecoin acquisitions and disposals using FIFO matching, calculating gains and losses in AUD. It captures the FX movement effect on USD-pegged stablecoins. If you earned yield on stablecoins through lending protocols or liquidity pools, those receipts need separate income treatment — check the coverage page.

Frequently asked questions
Are stablecoins taxable in Australia?
Yes. The ATO treats stablecoins such as USDT, USDC, and DAI as CGT assets despite their price peg. Disposing of a stablecoin — by selling it for AUD or swapping it for another asset — is a taxable event. Gains or losses arise from movements in the USD/AUD exchange rate between acquisition and disposal.
Is swapping crypto to USDT a taxable event?
Yes. Swapping a cryptocurrency for USDT (or any other stablecoin) is treated as a disposal of the cryptocurrency you gave up. A capital gain or loss arises on that disposed asset based on its AUD value at the time of the swap. The USDT you receive is then acquired at its AUD cost base for any future disposal.
