The statutory scheme and relevant provisions
10 The Australian GST is an indirect tax. Indirect taxes may be single stage taxes, for example, a tax on retail sales found in many countries in the world, or a bed tax as imposed in New South Wales in respect of hotel accommodation. They may also, if taxing the consumption of goods, operate at multiple stages in the course of goods being manufactured or imported until such time as they go into consumption, such as the wholesale sales tax in operation in Australia until the commencement of the GST.
11 Where there is a multi stage tax which operates with a number of taxing points, a problem, generally known as "cascading" will arise. If nothing is done to avoid cascading, the tax levied at each taxing point will be imposed on a value which already will have included tax payable at the previous taxing point or points. Cascading was, at least partly, avoided by the Australian wholesale sales tax by a system of quotation of certificates, so that in its operation, the tax was payable on the last wholesale sale or, if there was no such wholesale sale, on an assumed value calculated as a proxy for the last wholesale sale: Brayson Motors Pty Ltd (In liq) v Federal Commissioner of Taxation (1998) 156 CLR 651 at 657.
12 However, even though cascading was generally avoided in the Australian wholesale sales tax system, there was a problem that some inputs at least, attracted tax which was included in the amount upon which the tax was calculated and further, that there was no mechanism which enabled all inputs to be refunded in the event that the goods were exported. Arguably, therefore, Australian exporters might have been disadvantaged in competing with exporters from other countries which had taxing systems, such as value added taxation, which permitted the total tax payable to be identified and refunded to an exporter.
13 The genius of a system of value added taxation, of which the GST is an example, is that while tax is generally payable at each stage of commercial dealings ("supplies") with goods, services or other "things", there is allowed to an entity which acquires those goods, services or other things as a result of a taxable supply made to it, a credit for the tax borne by that entity by reference to the output tax payable as a result of the taxable supply. That credit, known as an input tax credit, will be available, generally speaking, so long as the acquirer and the supply to it (assuming it was a "taxable supply") satisfied certain conditions, the most important of which, for present purposes, is that the acquirer make the acquisition in the course of carrying on an enterprise and thus, not as a consumer. The system of input tax credits thus ensures that while GST is a multi-stage tax, there will ordinarily be no cascading of tax. It ensures also that the tax will be payable, by each supplier in a chain, only upon the value added by that supplier.
14 In ACP Publishing Pty Ltd v Commissioner of Taxation [2005] FCAFC 57 at [2], I described the characteristics of the Australian GST as follows:
"The GST is, in essence, the tax known in most countries as value added tax, a name which, perhaps, best describes the essence of the tax. The characteristics of a value added tax were aptly described by the European Court of Justice in Dansk Denkavit ApS v Skatteministeriet [1994] 2 CMLR 377 at 394-5 as being that it 'applies generally to transactions relating to goods or services; it is proportional to the price of those goods or services; it is charged at each stage of the production and distribution process; and finally it is imposed on the added value of goods and services, since the tax payable on a transaction is calculated after deducting the tax paid on the previous transaction.'"
15 I continued at [3]:
"These characteristics are displayed in the Australian legislation by the tax 'output tax' being levied, in effect, upon substantially all supplies (referred to in the GST Act as 'taxable supplies') being generally, although not exclusively, supplies of goods or services made by a registered person, or person required to be registered, for consideration… and the deduction referred to in Dansk (popularly known as an 'input tax credit') being given to a registered person, or person required to be registered, who makes a creditable acquisition, as that expression is defined."
16 In terms of GST theory, it is generally accepted that there are certain kinds of activities where the basic system of output tax on supplies and input tax credits on acquisitions will not lead to taxation on the value added by each supplier in the chain. The most important example is said to be financial transactions of financial institutions such as, but not confined to, banks, because they constantly borrow and lend and turn over money in a way that amounts, such as interest charged, will not represent the real value added by the financial institutions. Indeed, as the explanatory memorandum distributed with the bill which, as amended, later became the GST Act ("the EM") says in Chapter 1 [5.140]: "…there is no readily agreed identifiable value for supplies consumed by customers of financial services". In such a case, it is the margin or imputed margin that is the real economic subject of the supply. There are other examples where this may be the case, one of which is the leasing of, or other dealings with, residential property (not being new residential property).
17 By way of what may be seen as a compromise for the difficulties of applying the normal system of value added taxation to financial supplies and other difficult cases, value added taxation design has created a form of supply which is referred to in Australia as an input taxed supply but which, in international value added tax parlance, is referred to as an "exempt supply". An input taxed or exempt supply (and financial supplies made by financial institutions will be the main example) will not, generally speaking, attract output tax, but the entity which makes financial supplies will, likewise, not obtain an input tax credit for the tax payable on acquisitions it makes in the course of its enterprise of making input taxed supplies. This is subject to a unique Australian invention that certain kinds of activities, being, generally speaking, those which might be outsourced by entities making financial supplies and are in aid of making such supplies will, albeit that those activities might be defined as financial supplies, attract a reduced input tax credit of 75 per cent of the credit otherwise available. An example relevant to the present facts is debt collection activities - see reg 70-5.02 (Item 17) of the A New Tax System (Goods and Services Tax) Regulations 1999 (Cth)("the Regulations").
18 A definition of what constitutes an input taxed supply is to be found in Division 40 of the Act. The table of subdivisions for that Division refers to the following kinds of supplies as being input taxed, namely: financial supplies, residential rent, residential premises, precious metals, school tuckshops and canteens and fund-raising events conducted by charitable institutions.
19 A financial supply will be one which falls within the meaning of that expression in reg 40. It is unnecessary to discuss that definition in any detail, save in one respect. There will be a financial supply where there is the provision, acquisition or disposal of an interest recognised at law or in equity as property in any form, provided that provision, acquisition or disposal is for consideration and in the course of, or furtherance of, an enterprise, has the necessary connection with Australia and the supplier is a financial supply provider as defined in the Regulations: see reg 40-5.09. Perhaps counter-intuitively therefore, a financial supply will include something that is not a supply but an acquisition. An interest in a debt is, by virtue of Item 2 to the table to reg 40-5.09, a relevant interest, which if acquired will, in a case such as the present, result in the acquirer of the debt being taken to have made a financial supply. The definition of "financial supply" is fleshed out by examples in the Regulations and in schedules to the Regulations, which need no reference here. It suffices to say that it is common ground in the present case that the activity of the Trustee in acquiring the debts in the course of its enterprise will be an input taxed supply. This accepts that the Regulations have both the effect of rendering an acquisition a supply and further, as requiring that a supply made includes an acquisition received. This rather strange use of the regulation making power compounds confusion in the present case. It may raise at some stage a question of the validity of the Regulations themselves. However, that is not an issue which is before us.
20 The provisions dealing with the entitlement to input tax credits are to be found in Division 11 of the GST Act. Section 11-20 provides for there to be an entitlement to an input tax credit for any "creditable acquisition" made by a taxpayer. The expression "creditable acquisition" is defined in s 11-5. Relevantly, there must be an acquisition which is solely or partly for a creditable purpose: s 11-5(a). The acquisition must arise from a supply to the taxpayer which is a taxable supply: s 11-5(b). What a creditable purpose is will be found from s 11-15. Relevantly, that section provides:
"(1) You acquire a thing for a creditable purpose to the extent that you acquire it in carrying on your enterprise.
(2) However, you do not acquire the thing for a creditable purpose to the extent that:
(a) the acquisition relates to making supplies that would be input taxed; or
(b) the acquisition is of a private or domestic nature.
(3) An acquisition is not treated, for the purpose of paragraph (2)(a), as relating to making supplies that would be input taxed to the extent that the supply is made through an enterprise, or a part of an enterprise, that you carry on outside Australia.
(4) …
(5) An acquisition is not treated, for the purposes of paragraph (2(a), as relating to making supplies that would be input taxed to the extent that:
a. the acquisition relates to making a financial supply consisting of a borrowing; and
b. the borrowing relates to you making supplies that are not input taxed."
21 It is, perhaps, not unremarkable that s 11-15 of the GST Act bears, in its structure, some similarity to the general business deduction provisions of the Australian income tax law, ie s 51(1) of the Income Tax Assessment Act 1936 (Cth) and s 8-1 of the Income Tax Assessment Act 1997 (Cth). In both the GST provision and the income tax provisions, there is a need to pass first through a positive test. In the case of GST, the positive test is the requirement that the acquisition has been in whole or in part acquired in carrying on an enterprise. In the income tax context, there is the need to find that the loss or outgoing be incurred in gaining or producing assessable income, or in carrying on a business. In both cases apportionment arises where the positive test is only partly satisfied. Next, both require consideration of negative tests which exclude the allowance of a credit in the GST context or the allowance of a deduction in the income tax context. In the GST context the negative tests are those set out in s 11-15(2) of acquisitions relating to supplies that would be input taxed or acquisitions of a private and domestic nature. In the income tax context, the negative tests also involve the case where the loss or outgoing is of a private and domestic nature as well as where it is capital or of a capital nature. In both cases, a question of apportionment arises where the negative tests only partly apply.
22 The legislature might have followed the value added tax model applicable in the United Kingdom, which for present purposes can be said to allow an input tax credit where the acquisition is one that relates to the making of taxable supplies (including within that expression, supplies which in Australian GST parlance are GST free, called, in European countries, zero rated supplies). If that model had applied there is no doubt that the Trustee would not be entitled to an input tax credit. None of the acquisitions it made, whether for the feasibility study or for debt collection services, would have related to any taxable supply it made. The Trustee made no supply taxable or otherwise other than the financial supply. It merely collected money payable on the debts it acquired.
23 However, that is not the model which Parliament adopted in the GST Act. The question is whether the language of the GST Act reveals an intention to adopt a different approach which would permit the Trustee to obtain an input tax credit for the relevant acquisitions it made on the basis that they were wholly acquired in carrying on the Trust enterprise (this is agreed) and did not relate to making supplies that would be input taxed, which for present purposes, can be taken to mean the acquisition by the Trustee of the debts which were the subject of the feasibility study and the debt collection services, as the case may be.
