Goods and Services Tax: Digital Currency Conversion Determination 2019

This instrument prescribes how amounts of consideration expressed in digital currency are to be converted into Australian currency for the purposes of working out the value of a taxable supply under the goods and services tax rules. The conversion rule is a single formula: multiply the quantity of digital currency by "your particular exchange rate" on a specified conversion day (s 4). The determination applies to any entity that, when working out the value of a taxable supply, has any amount of consideration for the supply expressed in digital currency (s 3). It commences the day after registration (Commencement).

Mechanically, the determination (a) fixes the arithmetic to be applied (Amount of digital currency x your particular exchange rate on the conversion day, s 4); (b) prescribes how the conversion day is selected depending on the entity's GST accounting basis and residency status (definition of conversion day in s 5); and (c) defines permissible sources and processes for selecting "your particular exchange rate" including special treatment where an agreed rate has been struck between supplier and a registered recipient, and where exchange rates are only quoted in a foreign currency (definitions in s 5). The instrument requires consistent use of the chosen particular exchange rate (s 4). Other defined terms are imported from the GST Act where not otherwise defined in the determination (s 6).

The determination does not insert new tax bases, change who is taxable, nor set penalties or enforcement mechanics within its text. Its scope is narrowly technical: it governs currency conversion methodology when any part of the consideration is expressed in digital currency. It also cross‑refers to an earlier instrument , the Goods and Services Tax: Foreign Currency Conversion Determination 2018 , for converting foreign currency amounts into Australian currency when the relevant digital currency rates are quoted only in a foreign currency (s 5(b) Step 2 and link).

For an entity that needs to comply, the immediate operational effect is to require a documented, consistent choice of "particular exchange rate" and a clear rule for which date to use to determine that rate, together with a one-step arithmetic conversion mandated by s 4. The determination prescribes that, other than an agreed rate, the chosen exchange rate must reflect the GST inclusive market value of the digital currency in Australian currency (s 4). The legal text supplies definitions for agreed rate, conversion day, digital currency exchange, digital currency website, exchange rate, foreign currency, and transaction date (s 5).

The determination rests on a few compact concepts and definitions. These are the legal levers that translate a digital currency price into an amount of Australian currency for GST valuation purposes.

• Amount of consideration expressed in digital currency: any part of the consideration for a taxable supply that is denominated in digital currency falls within the determination's operation (s 3). The instrument does not define "digital currency" within its text; it instead defines operational terms like digital currency exchange and digital currency website (s 5) and relies on the GST Act for other terms (s 6).

• Particular exchange rate: the multiplier used in the formula at s 4 to convert a given amount of digital currency into Australian currency. The determination prescribes mutually exclusive ways of establishing "your particular exchange rate" (s 5). If the exchange rate is quoted in Australian currency, your particular exchange rate is the rate chosen from a digital currency exchange, a digital currency website, or the agreed rate, whichever you have chosen (s 5(a)). If the exchange rate is only quoted in a foreign currency, a two-step process applies: first choose a foreign currency exchange rate source (digital currency exchange, website, or agreed rate); then on the same day convert that foreign currency amount into Australian currency using the formula in paragraph 5 of the Foreign Currency Conversion Determination 2018 (s 5(b) Step 1 and Step 2).

• Agreed rate: a particular exchange rate that is agreed between a supplier and a registered recipient; it applies only to supplies made under that agreement and only for the period of the agreement (s 5, agreed rate). The instrument adds a constraint where the supplier and recipient are associates: any agreed rate in that circumstance must reflect the rate agreed by parties dealing at arm's length (s 5, agreed rate).

• Conversion day: the date used to pick the exchange rate for conversion. The conversion day depends on whether the entity accounts for GST on a basis other than cash, on a cash basis, or is a non-resident with particular registration status and supply types (s 5, conversion day). For non-resident entities , both limited registration entities and those that are not limited registration entities , the instrument provides specific alternative days for certain inbound or offshore supplies (s 5(c) and (d)).

• Digital currency exchange and digital currency website: the permitted public sources for exchange rates. A digital currency exchange provides a trading platform/exchange for buyers and/or sellers of digital currency and provides exchange rates publicly. A digital currency website provides exchange rates publicly without offering a trading platform (s 5, definitions). The determination requires that, if the exchange rate is quoted in Australian currency, the rate must be chosen from either a digital currency exchange, a digital currency website, or be the agreed rate (s 5(a)). The instrument requires that other than an agreed rate, your particular exchange rate must reflect the GST inclusive market value of the digital currency in Australian currency (s 4).

The determination applies directly to any entity that, in working out the value of a taxable supply, has any amount of consideration expressed in digital currency (s 3). The statutory text uses the broad term "entity", not limiting the instrument to suppliers, recipients, or registrants; accordingly, any legal person or arrangement that must calculate the value of a taxable supply and encounters consideration expressed in digital currency falls within scope.

Primary affected actors and roles identifiable from the instrument are:

• Suppliers who price or accept consideration in digital currency. They must convert that consideration into Australian currency using the formula in s 4 and must select and consistently apply a particular exchange rate in accordance with s 5. If the supplier has an agreement with a registered recipient fixing an agreed rate, the supplier may use that agreed rate for supplies under the agreement and for the period of the agreement (s 5, agreed rate).

• Registered recipients. A registered recipient can be the counterparty to an agreed rate under the agreed rate definition (s 5). The benefit of an agreed rate flows only where an agreement exists between supplier and a registered recipient. The instrument requires that an agreed rate between associates reflect an arm's length rate, indicating special treatment where related parties transact (s 5, agreed rate).

• Non-resident suppliers, subdivided by registration status. The determination sets out particular conversion day rules for non-resident entities that are not limited registration entities, including those making inbound intangible consumer supplies or offshore supplies of low value goods (s 5(c)). It provides alternative conversion day options for non‑resident entities that are limited registration entities (s 5(d)). These provisions indicate that non-resident suppliers will be required to adhere to conversion day selections that may differ from resident suppliers, and that those selections must be made for particular types of supplies.

• Entities that obtain exchange rates from digital currency exchanges or digital currency websites. The instrument prescribes that the particular exchange rate may be chosen from exchanges or websites that provide public rates (s 5, definitions; s 5(a)). Entities that rely on rates quoted in foreign currencies are affected because they must follow the two-step process in s 5(b), including a same-day conversion into Australian currency using the Foreign Currency Conversion Determination 2018.

The determination frames a small set of duties and a limited set of choices (rights) about how to value digital currency consideration for GST purposes. Those legal obligations and permitted choices are explicit in the text.

Key duties

• Duty to convert by formula: An entity must convert the amount of consideration expressed in digital currency using the formula set out in s 4: Amount of digital currency x your particular exchange rate on the conversion day. This is the central mandatory duty.

• Duty to use the chosen exchange rate consistently: s 4 requires that "You must use your particular exchange rate consistently." Once an entity selects a method for establishing its particular exchange rate, it must apply that method consistently across the relevant transactions.

• Duty to choose an exchange rate that reflects GST inclusive market value except where an agreed rate applies: s 4 requires that "Other than an agreed rate, your particular exchange rate must reflect the GST inclusive market value of the digital currency in Australian currency." This imposes an evidentiary or valuation obligation on entities that do not rely on an agreed rate.

• Duty to observe the conversion day rules: The conversion day definition in s 5 fixes which date governs the selection of the exchange rate. Entities accounting for GST on a basis other than cash must use the earlier of receipt date or transaction/invoice date (as chosen). Cash-basis reporters must use one of transaction date, invoice date, or receipt date. Non-resident entities that are not limited registration entities, and limited registration entities, have separate enumerated options for conversion days (s 5, conversion day).

• Duty to follow the foreign-currency conversion step when relevant: If the exchange rate is only quoted in a foreign currency, the entity must choose a foreign currency quote from a permitted source and then convert the foreign currency amount into Australian currency on the same day using the formula in paragraph 5 of the Foreign Currency Conversion Determination 2018 (s 5(b) Step 1 and Step 2). The requirement to perform the same-day conversion is a time-sensitive duty.

• Duty concerning agreed rates with associates: Where an agreed rate exists between supplier and recipient who are associates, the agreed rate must reflect the rate that would be agreed by parties dealing at arm's length (s 5, agreed rate).

The text of this determination does not contain express penalty provisions, infringement notices, or an enforcement regime within the instrument itself. The determination sets conversion methodology, definitions and timing rules but does not specify monetary penalties, criminal offences, or administrative sanctions. It also does not include internal compliance processes such as audit triggers or notice powers.

Because this instrument operates within the GST framework, compliance with its conversion methodology will feed into entities' GST reporting and liabilities. Any failure to apply the conversion method as required would manifest in incorrect GST values being reported or remitted. The determination does not specify what remedies apply in such cases; therefore, enforcement and penalty consequences for incorrect conversion or failure to follow the determination are not stated in the determination and will be governed by the legal and administrative framework within which GST is administered, including the GST Act and applicable administrative practice. The determination itself does not define or alter those wider mechanisms.

The determination requires consistent use of the chosen exchange rate (s 4) and requires particular treatments for agreed rates between associates (s 5, agreed rate). Non‑compliance with those specific duties could give rise to assessment adjustments, objections, or penalties if the underlying GST Act and its administration provide for them. However, those downstream enforcement and penalty processes are not prescribed here.

Practically, entities should be aware that the absence of penalty text in this instrument does not mean incorrect application is without consequence. The conversion feeds into GST calculations, and the GST Act and its administrative rules govern assessments, amendments, and penalties. The determination imports undefined expressions from the GST Act (s 6). That textual link indicates the determination is not a freestanding regime; enforcement and tax collection powers are exercised under the Act, but the determination does not itself articulate those powers.

If entities or advisers require detail on civil penalties, criminal sanctions, objection and review paths, or evidentiary standards for demonstrating that a chosen exchange rate reflects the GST inclusive market value of digital currency, they must consult the GST Act and relevant administrative guidance or rulings, since those matters are outside the content of this determination.

The determination contains two explicit points of interaction with other instruments and legal materials within the GST framework.

First, it imports the meanings of "all other expressions" from the GST Act (s 6). That means any term not defined within this determination must be interpreted by reference to the GST Act's definitions. The determination therefore operates as a subordinate instrument within the GST statutory architecture, and its application presupposes the substantive and procedural framework of the GST Act. The determination does not itself recast the GST Act's supply definitions, registration rules, or assessment and penalty provisions; rather, it supplies technical conversion methodology to be applied when assessing taxable values under that Act.

Second, the determination requires use of the formula at paragraph 5 of the Goods and Services Tax: Foreign Currency Conversion Determination 2018 when a chosen digital currency exchange rate is quoted only in a foreign currency (s 5(b) Step 2 and the link). This creates a direct cross‑instrument dependency: where the exchange rate for a digital currency is only available in a foreign currency, an entity must convert that foreign currency amount into Australian currency on the same day using the 2018 foreign currency conversion determination. The operational implication is that entities must consult and comply with two determinations when converting digital-currency consideration quoted in non‑Australian currencies: this instrument for the selection and timing mechanics, and the 2018 instrument for the foreign‑currency conversion formula.

Beyond those explicit cross‑references, the determination does not specify other statutory interactions. It does not, for example, reference income tax law, anti‑money laundering rules, contract law, or exchange regulation. Nonetheless, because it governs the valuation step in GST calculation, its outputs (the converted Australian-dollar amounts) will interact functionally with other statutory and regulatory regimes as those regimes refer to GST inclusive prices, taxable values, or amounts reported on activity statements. The determination does not alter the substantive application of those other regimes; it provides the method to produce the Australian-dollar figure that will enter into any statutory or regulatory instrument that relies on GST valuation.

Where the agreed rate is used between associates, the instrument requires the agreed rate to reflect an arm's length rate (s 5, agreed rate). That requirement signals potential overlap with transfer pricing or related-party valuation concerns within other legal regimes, but the determination itself simply imposes the arm's length constraint for agreed rates. How that arm's length requirement interacts with other statutory transfer pricing rules or documentation obligations is not addressed in the text and would be governed by those separate laws.

The instrument as presented contains only its identification and commencement notation and does not record any textual amendments or an amendment schedule. The headings show the instrument's name: "Goods and Services Tax: Digital Currency Conversion Determination 2019" and the commencement provision that the determination "applies on the day after it is registered" (Commencement). There is no legislative history contained in the text, such as earlier versions, amendment dates, or replacement instruments. The only cross‑instrument connection present is to the Goods and Services Tax: Foreign Currency Conversion Determination 2018 for conversion of foreign currency amounts into Australian currency where necessary (s 5(b) Step 2).

Because the determination is itself a subordinate instrument, amendments would typically be evidenced by subsequent instruments or legislative instruments amending or replacing it. No such amending instruments are recorded in the text provided. The instrument does not contain savings, transitional provisions, or express repeal language. It also does not include a separate explanatory memorandum, second-reading speech extracts, or a legislative note identifying prior drafts. The text therefore presents a single, self-contained determination as enacted.

For practitioners, the absence of an amendment record in the instrument means that any changes to these rules must be located by searching the register of legislative instruments or consolidated versions of GST regulations and determinations. The determination explicitly relies upon paragraph 5 of the Foreign Currency Conversion Determination 2018, which itself is an earlier instrument; any amendments to that 2018 Determination would therefore affect how the 2019 determination operates in cases where the chosen digital currency exchange rate is quoted only in a foreign currency (s 5(b) Step 2). The determination, however, does not itself record that dependency beyond the explicit reference.

The determination text contains no statements about litigation, case law, or judicial interpretation. It does not cite any cases, nor does it record prior disputes or settled positions. There is no internal record of court challenges, appeals, or legal proceedings in the instrument.

Given the instrument’s narrow technical scope, litigation would most likely arise only if a dispute emerged about whether an entity applied the conversion rules correctly, whether an agreed rate between associates properly reflected an arm's length rate, or whether the selected "particular exchange rate" reflected the GST inclusive market value as required by s 4. The instrument does not itself canvass or summarise any such disputes.

Because the determination imports undefined terms from the GST Act (s 6), judicial interpretation of those imported terms in other contexts could be relevant to disputes involving conversion under this instrument. Similarly, interpretation of paragraph 5 of the Foreign Currency Conversion Determination 2018 could be material where foreign-currency quoted rates are involved. However, none of those interpretative issues are addressed in the determination, and no litigation history is recorded in the text supplied.

Practitioners seeking authorities on contested conversion practices or on the determination’s interpretation must therefore look outside this instrument to administrative guidance, determinations under the GST Act, and any relevant Tribunal or court decisions interpreting conversion methods, agreed rates between associates, or obligations to reflect GST inclusive market value. The determination itself contains no litigation citations or history.

The text contains a number of operational nuances and constraints that can produce compliance risk where they are overlooked. These are concrete points in the instrument that practitioners should treat as potential pitfalls.

• Any amount expressed in digital currency triggers application: The determination applies when any amount of consideration for a taxable supply is expressed in digital currency (s 3). Even a partial price component in digital currency requires conversion under the instrument. Failure to identify partial digital-currency components may lead to incorrect valuation.

• Consistency requirement: s 4 requires that "You must use your particular exchange rate consistently." The instrument does not specify the scope or period for "consistent" beyond the agreed-rate limitation. Entities must therefore document their method choice and apply it across similar transactions to avoid inconsistency that could trigger audit queries or adjustment.

• GST inclusive market value requirement: Except where an agreed rate applies, the particular exchange rate must "reflect the GST inclusive market value of the digital currency in Australian currency" (s 4). Entities must therefore ensure the rate selected produces an Australian-dollar figure that represents GST inclusive market value. The determination does not prescribe precise evidence or valuation procedures for demonstrating that condition, so entities may face uncertainty about what documentary proof suffices.

• Agreed-rate limits and associate constraint: An agreed rate is available only between a supplier and a registered recipient, and only for supplies under the agreement and for the period of the agreement (s 5, agreed rate). Where the parties are associates, the agreed rate must reflect an arm's length rate (s 5, agreed rate). Parties should therefore be cautious that an informal or undocumented "agreed" exchange rate may be challengeable, especially for related‑party transactions.

• Conversion day complexity: The conversion day depends on accounting method and residency status and varies by supply type (s 5, conversion day). For entities that account other than on a cash basis, the conversion day is the earlier of receipt date or the chosen transaction/invoice date; for cash-basis reporters it is one of transaction date, invoice date or receipt date. Non-resident entities have separate alternatives. Misidentifying the conversion day will yield a different exchange rate and therefore a different GST amount.

The determination lays out a concise, stepwise compliance path for entities that encounter consideration expressed in digital currency. Below is a practical compliance checklist tied to the specific text.

1. Identify applicability (s 3)

   • Determine whether any part of the consideration for a taxable supply is expressed in digital currency. If yes, the determination applies. This includes partial payments, exchange-rate denominated line items, or any component expressed in digital currency.

2. Determine the appropriate conversion day (s 5, conversion day)

   • If you account for GST on a basis other than cash, use the earlier of: a) the receipt date (the day on which any part of the consideration is received for the supply), or b) the transaction date or the invoice date, whichever you have chosen.
   • If you account for GST on a cash basis, use either the transaction date, the invoice date, or the day on which any consideration is received for the supply.
   • If you are a non‑resident that is not a limited registration entity and you make inbound intangible consumer supplies or offshore supplies of low value goods, you may use: a) a day specified in (a) or (b) for other types of supplies; or b) for all your inbound intangible consumer supplies or offshore supplies of low value goods, either the final day of the relevant tax period in which GST is payable, or the earlier of the day on which you lodge your activity statement for a tax period or the due date for lodgement of that activity statement.
   • If you are a non‑resident that is a limited registration entity, your conversion day for all supplies may be a day specified in (a) or (b), or the final day of the relevant tax period in which GST is payable, or the earlier of the day on which you lodge your activity statement for a tax period or the due date for lodgement.

3. Select "your particular exchange rate" (s 5)

   • If the exchange rate is quoted in Australian currency, you may choose the rate from: a) a digital currency exchange (a trading platform/exchange that provides exchange rates publicly); or b) a digital currency website (a website that provides exchange rates publicly, without providing a trading platform); or c) an agreed rate between supplier and a registered recipient, provided the agreement covers the supply and the period in question and, if the parties are associates, the agreed rate reflects an arm's length rate.
