Cryptocurrencies, although not as popular as in years gone by, have a unique tax treatment that practitioners should be aware of.

It’s been more than 10-years since the advent of bitcoin and the term ‘cryptocurrency’ entered the public consciousness. However, neither bitcoin nor the many thousands of cryptocurrencies that have followed have become widely used for payments. Instead, people are more likely to use cryptocurrencies as a speculative high-risk investment class. Cryptocurrency is essentially a digital representation of value that is neither issued by a central bank or a public authority, and usually not attached to a national currency. Cryptocurrency can be transferred, stored or traded electronically.
Essentially, there are three ways to acquire cryptocurrency:

  • Buying it through an online exchange system that put sellers in touch with buyers. Purchases are then made by transferring money via online banking. Typically, cryptocurrency is stored in an online wallet.
  • Providing goods and services in return for cryptocurrency.
  • Mining — as in the process by which cryptocurrency is created, whereby a computer crunches through a set of complex mathematical exercises and the end result is a ‘piece’ of cryptocurrency.

This article touches on the broad tax treatment of this form of currency.


Cryptocurrency is generally regarded as a CGT asset. The disposal of cryptocurrency to a third-party may constitute a CGT event (A1). Disposals can take several forms: selling or gifting the cryptocurrency; trading or exchanging it; converting it to Australian dollars; or using it to acquire goods or services.
A capital gain is made when the proceeds from the disposal of the cryptocurrency exceed the cost base. The capital proceeds from the disposal of the cryptocurrency is the money or the market value of any other property received in respect of the disposal. The main element of the cost base is the money paid or the market value of any other property a buyer gave in acquiring that cryptocurrency. The 50% discount may also apply where the currency is held for 12 months or more. See example below.

In the event that the cryptocurrency received cannot be valued, the capital proceeds from the disposal are worked out using the market value of the cryptocurrency disposed of at the time of the transaction.
Note that, as with shares, if a cryptocurrency increases or decreases in value while held by a taxpayer, this does not result in a capital gain or loss. This is because there is no disposal.


Pursuant to subsection 118-10(3) of the Income Tax Assessment Act 1997 (ITAA 1997), a capital gain made from a personal use asset is disregarded if the first element of the cost base is $10,000 or less. In addition, any capital loss made from a personal use asset is disregarded under subsection 108-20(1). These provisions apply equally to cryptocurrency. The relevant time for determining whether the cryptocurrency is a personal use asset is at the time of its disposal.
Examples where cryptocurrency is held for personal use may include where it is kept or used mainly to make purchases of items for personal use or consumption, for example, clothing or music.
This personal use carve-out, however, would not apply where the cryptocurrency is kept or used mainly for the purpose of profit-making as an investment (to be sold or exchanged at a later time when the value has increased) or to facilitate purchases or sales in the course of carrying on business.


It may be the case that a gain on the disposal of cryptocurrency (that is not a personal use asset) is assessable as ordinary income rather than a capital gain. Where this is the case, the CGT discount will not be available.
In the case of an isolated transaction that is not carried out as part of a business operation, the ATO is of the view that a gain will generally be ordinary income where the taxpayer’s intention or purpose in entering into the transaction was to make a profit or gain. In determining whether an isolated transaction amounts to a commercial transaction, factors to consider include:

  • the nature of the entity making the transaction
  • the scale of the activities
  • the amount of money involved
  • the nature, scale and complexity of the transaction
  • the manner in which the operation or transaction was entered into or carried out, including the use of agents or professional advisors, and
  • the timing of the transaction or the various steps in the transaction.


Cryptocurrency can constitute ‘trading stock’ for the purposes of the ITAA 1997, and will be treated as such where:

  • it is held by a taxpayer carrying on a business of mining and selling bitcoin, or
  • a taxpayer is carrying on a cryptocurrency exchange business, or
  • it is received as a method of payment by any business that sells goods where the cryptocurrency is held for the purposes of sale or exchange in the ordinary course of the business.

Proceeds from the sale of cryptocurrency held as trading stock in a business are ordinary income, and the cost of acquiring cryptocurrency held as trading stock is deductible. The CGT rules do not apply.


Division 775 of the ITAA 1997 provides rules for recognising foreign currency gains and losses for income tax purposes. The ATO’s longstanding position is that gains or losses made from cryptocurrencies, such as bitcoin, cannot give rise to foreign currency gains or losses because such currencies do not constitute ‘foreign currencies’ under the ITAA 1997.
In June 2020, the Administrative Appeals Tribunal affirmed this position in Seribu Pty Ltd v Commissioner of Taxation [2020] AATA 1840 (16 June 2020). The taxpayer, Seribu Pty Ltd, dealt in bitcoins, and made a loss on those dealings. Seribu’s position was that it should be entitled to deduct that loss under the rules in Division 775 of the ITAA 1997. That division is limited to losses on foreign currency as defined in s 995-1. Yet the Commissioner insisted a cryptocurrency like bitcoin is not a foreign currency for the purposes of Div. 775 and hence Seribu’s loss was not deductible.
The AAT agreed with the Commissioner, noting that section 995-1 of the ITAA 1997 defines foreign currency as a currency other than an Australian currency established by the Australian government under the Currency Act (1965). 'Other currency' must be interpreted in light of that comparator.
Accordingly, ‘other currency’ must be an official currency issued or recognised by a sovereign state. A unit of exchange will not be currency unless it is created under the laws of another sovereign country (that has the capacity to pass laws). The AAT ruled, therefore, that Bitcoin is not a currency or foreign currency for income tax purposes. As such, Seribu (and other taxpayers in its position) was not entitled to deduct losses on bitcoins (and by extension other cryptocurrencies) under the rules in Div. 775.


Taxpayers dealing with cryptocurrency need to keep the records laid out in the table below.

Finally, for those using cryptocurrency for both personal use and for investment or business purposes, it is particularly important to keep clear records. This is because it will fall to them to show the intention behind each transaction.
