For companies in the space industry, tax is an important factor in determining where to base themselves. This chapter surveys the basic conceptual framework relevant to the direct taxation of space companies, focusing particularly on the operation of satellites. While United Kingdom corporate taxation is the author's area of practice, this chapter does not focus on any particular jurisdiction; rather, it highlights concepts and issues that are common to many jurisdictions.
II CORPORATE TAXATION
i Foundational concepts
Tax laws, both domestic and international, typically identify taxable persons or transactions by reference to a physical presence in, or connection with, a particular territory. Thus, extraterrestrial commercial activities do not always fit naturally within the current conceptual framework.
Direct taxes are levied on a person's income, profits or gains, whereas indirect taxes are imposed on transactions involving the production, consumption, sale, transfer or registration of assets, goods or services. As regards direct taxation, commercial space businesses are generally carried on through corporate vehicles, and they may, therefore, be subject to corporate income tax or corporation tax.
As a matter of domestic law, residence for corporate tax purposes is typically determined by a test relating to the place in which the company is incorporated or the place from which it is managed or controlled, or both. The detailed mechanics of the tax code then determine where a particular corporate tax system lies on the spectrum between worldwide taxation (i.e., taxing resident companies on their global profits, whether generated in that country or abroad) and territorial taxation (i.e., taxing companies only on their profits generated within that country). Non-resident companies, on the other hand, are generally taxed only on profits generated in the taxing state, whether through a permanent establishment or (in some cases) otherwise.
Double taxation can arise if two countries seek to tax the same profits of a company. This might be the case, for example, if a company were to be treated as resident in two countries under their respective domestic laws. Domestic relief may be given for double taxation. Tax treaties are also bilaterally negotiated to allocate taxing rights between the signatory states and thereby minimise double taxation. Such treaties are often based on a historic version of the Model Tax Convention on Income and on Capital published, and periodically updated, by the Organisation for Economic Co-operation and Development (OECD).
ii Application to commercial space activities
The border between airspace and outer space is not defined in international law. This is pertinent because, while states generally claim rights in respect of the airspace above their territories, the international community has rejected the notion of sovereignty in respect of outer space.2 For example, the 1967 Outer Space Treaty, one of the foundational texts of international space law, provides that outer space is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.3
However, there are no clear and generally accepted definitions of 'airspace' and 'outer space'. This has left the door open for attempts to assert sovereignty over outer space in certain respects. For instance, in 1976, seven equatorial countries made the Bogotá Declaration, asserting their sovereignty over the segments of the geostationary satellite orbit directly above their respective territories.4 The signatories contended that the geostationary orbit is not part of outer space, but is a 'physical fact' resulting from Earth's gravity, therefore constituting a scarce natural resource that they were entitled to control.5
This background informs the question of whether a satellite in orbit above a particular country generates a taxable presence in that country for its operator. The Commentary on the 2017 OECD Model Tax Convention observes that a permanent establishment may only be considered to be situated in a contracting state if the relevant place of business is situated in the territory of that state.6 Accordingly, whether a satellite in geostationary orbit could constitute a taxable permanent establishment for the satellite operator depends upon how far the territory of a state extends into space. However, the Commentary states that no OECD Member Country would agree that the location of geostationary satellites can be part of the territory of a contracting state under the applicable rules of international law. It adds that the area over which a satellite's signals may be received (the satellite's 'footprint') cannot be considered to be at the disposal of the operator of the satellite so as to make that area a place of business of the operator. At present, therefore, the position of the satellite itself and the area that it serves are not usually significant factors from a direct tax perspective: the crucial factor is the tax residence of the satellite operator.
While national governments and international organisations continue to devote considerable attention and resources to the burgeoning commercial space industry, rather less attention has been given to ensuring that tax systems keep pace. However, if the industry continues to grow rapidly over the coming years and decades, it seems likely that space tax will increasingly come to the fore as a topic for debate.
Parallels may be drawn with the way in which the taxation of digital services has recently become a political battlefield. Arguably, cross-border digital services have exposed the shortcomings of tax systems that are predicated upon physical presence. In response, the OECD, under the aegis of its wide-ranging Base Erosion and Profit Shifting Project, is leading efforts to reshape the international tax landscape in fundamental ways, so as to give due weight to the location of multinational businesses' customers when allocating taxing rights between different jurisdictions. Space tax could eventually go down a similar path; the risk, though, is that (as in the digital taxation arena) individual countries will adopt unilateral measures, resulting in a tax landscape for space companies that is ever-shifting and difficult to navigate.
