I don't think Australian crypto community need to worry just as yet. This is a draft taxation guideline and nothing has been finalized yet. The Australian taxing authority is actually proposing this law and asking citizens to provide their feedback. While asking feedback is a good thing, but there are few areas in the proposed law, which are extremely worrying. Let me quote few of these below,
Where you exchange one cryptocurrency for another cryptocurrency, you dispose of one CGT asset and acquire another CGT asset. Where you receive property instead of cash as part of a transaction, you are usually taken to have received the market value in Australian dollars of the property received.
This essentially means, if you exchang your bitcoin for ETH, you will have to consider it as an acquisition of asset and needs to be termed in AUD.
So lets take an hypothetical example. Assume you have exchanged 1 BTC for 20 ETH. If 1 ETH is price at 400 AUD at the time of transaction, you are actually receiving 8000 AUD worth of asset. Now if tomorrow ETH price goes down to 300 AUD, will it be considered as a short term capital loss? No clear answer to that. Point of concern!
It does not matter how many exchange transactions you undertake. You need to undertake this process for every transaction occurring during the income year.
That means, you have to repeat the above described calculation every time you trade and convert the amount to AUD for record keeping. This law is unnecessarily complicating the matter and it will discourage a lot of active traders in Australia. However, the only hope is that, the law is still not enforced and the government is looking for public feedback on it.
