A MULTILATERAL OPTION FOR VAT IN INTERNATIONAL TRADE?

Abstract

Value-added tax, the most common form of consumption tax in the world, operates on a destination principle to ensure it is levied only in the place of final consumption in cases of cross-border transactions. The international trade in services and intangibles through digital means poses two challenges: finding the place of consumption and collecting the tax when services supplied by businesses in one jurisdiction are instantaneously consumed by customers in another. This article examines these challenges and considers how unilateral action and soft international responses have so far failed to achieve consistent destination basis taxation. An alternative option would be to adopt a hard multilateral response that would overcome the limitations of unilateralism and soft-law approaches and achieve consistent destination basis taxation in the digitalised economy.

1 A broad definition of the digital economy is adopted by the G20 to reflect the fact that not only information and communication technology sectors but also traditional sectors have become integrated with the digital economic ecosystem.

Although the specific term used in jurisdictions can differ, the essence and nature of a VAT and a goods and services tax (GST) are identical. See also EY, Worldwide VAT, GST and Sales Tax Guide 2021 (EY 2021) 259–60, 1623. For simplicity and convenience reasons, the article uses VAT to refer to VAT, GST, and similar taxes. Where the title of legislation, official documents and publications uses VAT or VAT/GST, the article uses that term rather than VAT.

3 VAT has contributed about 20 per cent of total tax revenue on average in OECD countries. See OECD (n 2) 16; OECD, Revenue Statistics 2020 (OECD Publishing 2020) 17.

Imposing VAT based on where the supplier is located is called origin taxation. A few jurisdictions apply the origin principle to certain transactions, eg Brazil where exports are not zero rated in practice due to administrative barriers and limiting legal instruments.

14 For example, the estimated EU VAT revenue loss was around EUR 170 billion (2013) and EUR 150 billion (2016). European Commission, ‘VAT Action Plan: Commission Presents Measures to Modernise VAT in the EU’ (1 April 2016) <http://europa.eu/rapid/press-release_IP-16-1022_en.htm>; European Commission, ‘VAT: EU Member States still Losing Almost €150 billion in Revenues according to New Figures’ (21 September 2018) <https://europa.eu/rapid/press-release_IP-18-5787_en.htm>. In New Zealand, the lost GST revenue from cross-border services and intangibles and goods was estimated to be about NZD 40 million per year. New Zealand Inland Revenue, GST: Cross-border Services, Intangibles and Goods (Inland Revenue 2015) 5.

15 VAT double taxation occurs ‘where two states levy VAT on the same supply’. Situations that can give rise to this are when national rules determining the place of taxation differ, when the rules, albeit similar, are subject to either different legal interpretation or there is a different interpretation of the underlying facts, or when a supply is characterised differently. T Ecker, A VAT/GST Model Convention (IBFD Publications 2013) 35, 37–45. VAT non-taxation occurs ‘when no country has imposed the tax on the relevant subject matter’, which means no tax burden will be passed onto consumers. R Millar, ‘Intentional and Unintentional Double Non-taxation Issues in VAT’ (2009) Sydney Law School Legal Studies Research Paper No 09/45, 8. The non-taxation concerns the practical difficulty of collecting the tax, particularly if the customer is a final consumer unregistered for VAT purposes.

16 The most important OECD guidelines are the OECD Guidelines (n 8). The OECD Committee on Fiscal Affairs developed the International VAT/GST Guidelines in 2006, with the latest version issued in 2017.

22 Under income taxation, the two nexuses overlap and two jurisdictions have the legitimate right to impose tax. The jurisdictions in question usually resolve the overlapping claims by way of a bilateral income tax treaty in which they agree to a division of taxing rights, with treaties usually based on either the OECD, Model Tax Convention on Income and on Capital 2017 (OECD Publishing 2019) (OECD Model) or United Nations, Model Double Taxation Convention between Developed and Developing Countries 2021 (United Nations 2021) (UN Model) or both.

23 Allowing the destination country to tax creates a level playing field for all businesses in the same market.

24 This is what happened in R v Dawn's Place Ltd (2006) FCA 349. In this Canadian case, the appellant, Dawn's Place Ltd, operated a website permitting the downloading of adult content images and video files on payment of a subscription fee. The contentious issue was whether the supply was made to the consumer at the point the copyrighted material was viewed or at the point at which it was made available for transmission.

25 Cloud computing, for example, supplied by a business in one country to a customer in another will not be readily known to the tax authority of the other country since there is no ‘border’ in the virtual cloud.

29 OECD Guidelines (n 8) 15. For a detailed discussion of the invoice-credit method, see James (n 12) 70–77. While the invoice-credit method is applied by almost all jurisdictions, another method, the subtraction method, is used by Japan. Under the subtraction method, VAT is levied on an accounts-based measure of value added determined as the difference between the value of purchases and the value of outputs. See LP Ebrill, M Keen and VJ Perry, The Modern VAT (International Monetary Fund 2001) 20–2.

30 For example, the EU place of taxation rules differ between supplies of goods and supplies of services. For services, the place of supply determines the place of taxation. By contrast, New Zealand uses the place of supply rule as a first step to determine the place of taxation. Cockfield et al (n 21) 253–54.

31 In the EU, from 1 January 2015, electronic services, telecommunications and broadcasting are taxed where the customer is established, has its permanent address or usually resides. Council Implementing Regulation (EU) No 1042/2013 (amending Implementing Regulation (EU) No 282/2011 regarding the place of supply of services) art 1 (see insertions of arts 24a–24f to Implementation Regulation (EU) No 282/2011). Specific place of supply rules are applied based on whether the supply is a B2B or B2C supply. Notably, art 24a applies to both B2B and B2C supplies, while art 24b applies only to B2C transactions. See Council Implementing Regulation (EU) 2017/2459 (amending Implementing Regulation (EU) No 282/2011) art 1 (adding specific requirements to art 24b of the Council Implementing Regulation (EU) No 282/2011)).

32 In Australia there is no single place of supply rule, and instead one must consider the ‘connected with the indirect tax zone’ rules, the GST-free rules, the input tax credit entitlement rules, and the relationship with the concept of an enterprise carried on in or outside Australia. For a comparative discussion of the Australian and New Zealand place of taxation rules, see Cockfield et al (n 21) 258–60, 264–8. For Singaporean rules, see The Goods and Services Tax Act (Singapore Cap 117A) sections 13, 15. Digital services supplied by overseas suppliers to Singapore became taxable from 1 January 2020. Inland Revenue Authority of Singapore, ‘GST on Imported Services’, <https://www.iras.gov.sg/irashome/GST/GST-registered-businesses/GST-and-Digital-Economy/GST-on-Imported-Services/>.

34 OECD Guidelines (n 8) Ch 3.

35 ibid. Guidelines 3.2 and 3.6. In some circumstances where a supply is made to a business entity that has multiple establishments in different jurisdictions, an additional analysis is needed to determine which of the jurisdictions has the taxing right over the services. OECD Guidelines (n 8) 44–5.

36 OECD Guidelines (n 8) Guideline 3.5.

37 This is the case whether the supply of services will be further supplied onward by the customer to a third party or is instead directly provided to a third party or paid for by a third party. OECD Guidelines (n 8) 49–64.

38 OECD Guidelines (n 8) 78–9. These specific rules are needed in those circumstances where using general rules could not achieve destination taxation.

40 Such objective is considered a principle of good tax design. See, eg Commonwealth of Australia, Australia's Future Tax System: Report to the Treasurer (December 2009) Pt 1, 17; J Mirrlees et al, Tax by Design: The Mirrlees Review vol 2 (OUP 2011) 22; MP Devereux et al, Taxing Profit in a Global Economy (OUP 2021) 53–5.

41 Cockfield et al (n 21) 235–374. The book notes rules and measures adopted by some earlier reformers such as Australia and the EU.

42 For example, Australia amended its GST law effective 1 July 2017 to impose GST on intangible supplies, such as supplies of digital content, games and software as well as consultancy and professional services, provided by foreign suppliers to Australian consumers. A New Tax System (Goods and Services Tax) Act 1999 (Cth) sections 9–10(2)(b), 9–25(5); Australian Treasury, ‘Tax Laws Amendment (Tax Integrity: GST and Digital Products) Bill 2015: Exposure Draft Explanatory Material’ <https://treasury.gov.au/sites/default/files/2019-03/C2015-026_EM_Tax_Integrity_GST_and_Digital_Products.pdf>.

43 For example, the EU VAT law defines electronically supplied services as those ‘which are delivered over the Internet or an electronic network and the nature of which renders their supply essentially automated and involving minimal human intervention, and impossible to ensure in the absence of information technology’. See Council Implementing Regulation (EU) 282/2011 of 15 March 2011 (laying down implementing measures for Directive 2006/112/EC on the common system of value added tax) art 7(1). Similarly, Japan's Consumption Tax Act defines the provision of electronic services broadly with examples of included supplies and of exclusions. National Tax Agency (Japan), Revision of Consumption Taxation on Cross-border Supplies of Services (May 2015, revised December 2016) <https://www.nta.go.jp/english/taxes/consumption_tax/cross-kokugai-en.pdf>.

44 Council Implementing Regulation (EU) 282/2011 of 15 March 2011, art 7(2). For Japan's rules, see National Tax Agency (Japan) (n 43).

45 For example, in South Korea, digital services have been expanded to include advertising services, cloud computing, and intermediary online-to-offline services from 1 July 2019 (previously limited to ‘content-oriented’ transactions). KPMG, VAT/GST Treatment of Cross-border Services: 2017 Survey (KPMG International November 2017) (KPMG 2017 Survey) 7; KPMG, Taxation of the Digitalized Economy: Developments Summary (KPMG 22 July 2021) 141.

46 An example is New Zealand. See Taxation (Residential Land Withholding Tax, GST on Online Services, and Student Loans) Act 2016 (effective 1 October 2016 for online services) sections 55 (introducing new section 8B, remote services, into the Goods and Services Tax Act 1985 (NZ)) and 72 (introducing new sections 60C and 60D, electronic marketplaces, into the Goods and Services Tax Act 1985 (NZ)).

48 Directive 2006/112/EC (of 28 November 2006 on the common system of value added tax) arts 44, 45, 58. Prior to 2015, intra-EU B2C supplies of digital services were taxed in the Member State of the supplier. See also Council Implementation Regulation (EU) No 1042/2013 (n 31) art 2.

49 However, from 1 January 2019, the place of taxation has been modified to be the Member State of the supplier if the supplier is an EU-established business making B2C supplies of digital services as well as telecommunications and broadcasting, and the relevant supplies do not exceed a certain threshold. Council Directive (EU) 2017/2455 (of 5 December 2017 amending Directive 2016/112/EC and Directive 2009/132/EC as regards certain value added tax obligations for supplies of services and distance sales of goods) art 1(1) (see amendments to art 58(2) and (3)).

While the determination in B2B supplies can be made based on the customer's business VAT registration information, for B2C supplies there are no specified proxies or presumptions available as a guide for foreign suppliers.

122 The mutual agreement procedure (MAP) is prescribed in art 25 of the OECD and UN Models on income and capital. It could be argued that the express statements in arts 24 (non-discrimination), 26 (exchange of information) and 27 (assistance in the collection of taxes) indicate that those articles are not limited to covered taxes (ie taxes on income and capital) in art 2. The absence of such an express statement in art 25 could be taken to imply that its scope is limited to covered taxes. However, art 25(1) refers to ‘taxation not in accordance with the provisions of this Convention’, and thus ‘taxes’ are not limited to taxes on income and capital in the sense of art 2(2). See E Reimer and A Rust (eds), Klaus Vogel on Double Taxation Conventions (4th edn, Kluwer Law International 2015) 1786. Since the OECD and UN Models include arts 24, 26 and 27 which are not limited to covered taxes, the result would seem to follow that a taxpayer who considered that an action of a Contracting State breached art 24, for instance in relation to VAT that was not a covered tax, would be able to seek the MAP remedy under art 25.

129 Actual DTAs based on the OECD or UN Model usually contain articles from 24 onwards that are applicable to other taxes for administrative cooperation. On a multilateral level, the Multilateral Convention on Mutual Administrative Assistance in Tax Matters (as amended by Protocol in 2010) applies to all taxes including VAT.

136 Non-taxation occurs when an imported supply of services is not taxed, such as where there is a lack of effective collection mechanisms in the importing jurisdiction. Non-taxation also occurs when supply of services (eg healthcare) is exempt or when it is difficult to tax the supply on its value added (eg financial services). Non-taxation of B2B cross-border supplies is less significant than B2C supplies as VAT is not meant to tax intermediate businesses, except when the business makes supplies that are exempt from VAT without credits or is an entity not required for VAT, meaning the business needs to bear VAT. Millar (n 15) 7–21; Millar, ‘Looking Ahead: Potential Solutions and the Framework to Make Them Work’ (n 119) 7, 9. For the neutrality principle, see OECD Guidelines (n 8) Ch 2.

This document notes, on page 3 paragraph 3, that indirect taxes, particularly VAT, ‘was for a long time not part of the Committee's workplans, partly due to the initial general Committee focus on tax treaties, and the limited resources to expand into areas of activities there were often not part of Member's areas of expertise’. The document also shows that the UN Tax Committee considered developing guidance on indirect tax issues especially for developing countries.

142 While speculative it suggests why the world moved so quickly with the adoption of the MLI but not with a parallel VAT convention.

143 This is also speculative, but may explain why there is a lack of leadership role from the EU.

147 At the US state level, specific sales thresholds apply to require remote sellers to collect and remit retail sales taxes which vary from state to state. Depending on the state, remote sellers may be required to collect tax on sales of services and digital goods in addition to physical goods. The variations may cause compliance burdens to both local and foreign businesses making inter-state and cross-border digital sales. KPMG (2021) (n 45) 149.

The author notes in a more recent article that China's influence may be growing in respect of international tax governance, but the US continues to be the major power driving international tax reform. While the US seems to have shown a US-centric multilateralism in the area of international tax, it is not clear how China's ‘true multilateralism’ will play out in global tax governance. The author also notes that China relies on international tax rules to generate revenue as VAT is the largest revenue source in the country.

153 As noted by think tank the Hinrich Foundation, the most recent remarks given by high-ranking US and EU officials imply that the era of globalisation is approaching an end as the leaders seem to intend to move to trade within a much more narrowly defined group of ‘friends’ who share common ‘values’.
