Your tax invoice must meet the normal tax invoice requirements and include either:
- the GST payable in Australian dollars
- sufficient information to work out the GST payable in Australian dollars.
Examples of sufficient information includes the:
- price expressed in Australian dollars
- value expressed in Australian dollars, or
- conversion rate used by the supplier, or a statement, to work out the GST payable if it is not in Australian dollars.
If you use digital currency to make a purchase for your GST-registered enterprise and claim a GST credit, the GST amount of the credit in your business activity statement must be in Australian dollars.
To work out your GST credits, your tax invoice will include either:
- the GST amount in Australian dollars
- sufficient information to determine the GST amount in Australian dollars.
To work out the value of your digital currency for your business activity statement, you must use the exchange rate on the conversion day that applies to you.
If the exchange rate is in Australian dollars, you may choose to use the exchange rate:
- from a digital currency exchange or website, or
- agreed on between the supplier and the recipient.
If the exchange rate is in a foreign currency, you must convert the amount expressed in foreign currency to Australian dollars.
For the formula to convert foreign currency to Australian dollars, see FOREX 2018/1 Goods and Services Tax: Foreign Currency Conversion Determination 2018.
The conversion day is the date you use to convert your digital currency into Australian dollars.
If you account for GST on a non-cash basis, your conversion day is determined by whichever happens first of either the:
- day you receive any of the payment
- transaction date or invoice date.
If you account for GST on a cash basis, your conversion day can be the transaction date, invoice date or the day you receive any of the payment.
Conversion day for non-resident entities
For more information on determining your conversion day if you are a non-resident entity, see DCC 2019/1 Goods and Services Tax: Digital Currency Conversion Determination 2019.
Example: accepting digital currency as payment for your services
Kristin is registered for GST and accounts for GST on a cash basis. She makes taxable supplies of digital marketing services. Kristin accepts CostyCoin (a digital currency) as payment for her services.
Peter pays Kristin 2.5 CostyCoins (a digital currency) for her taxable supply of digital marketing services.
Kristin must report and pay GST on her taxable supply. When reporting and paying her GST, the amount must be in Australian dollars (AUD).
Kristin locates an exchange rate for CostyCoin quoted in AUD on Lock-In-Exchange Pty Ltd's website. Lock-In-Exchange is a digital currency exchange that provides exchange rates publicly.
Kristin's conversion day is the day the transaction took place. Lock-In-Exchange's exchange rate for 1 CostyCoin on the conversion day is $2,200 AUD.
Kristin works out the GST inclusive value of the taxable supply to Peter:
2.5 × $2,200 = $5,500.
Kristin must report $5,500 in her activity statement and pay $500 in GST. She also issues a tax invoice to Peter showing GST payable in Australian dollars of $500.End of example
