Abstract

Effective from the 1st October 2001, the basis for taxation in South Africa was fundamentally amended by virtue of the introduction of the Eighth Schedule as the embodiment of a tax regime based on the Haig-Simons comprehensive model of income. It is known as ‘Capital Gains Tax', or CGT, the tax base of which is all non-trade net accretions to wealth, subject to certain exclusions. In contrast to the gross income definition and associated jurisprudence, the definition of a tax event for the purposes of the CGT regime includes the notion of the creation of an asset. The guidance of the South African tax authority in conjunction with academic commentary propose the construction that ‘creation' must be understood with reference to a taxpayer's counterparty. This research supports the opposing view; it is necessary to give effect to the underlying statutory purpose that the term is not so narrowly interpreted as to exclude the creation of real rights. From the perspective of South African tax policy, a crypto asset has been defined as a ‘financial instrument' in order to ensure it is not treated as a currency, and falls outside the definition of ‘personal-use asset' for the purposes of the CGT regime. The progenitor of modern crypto assets, Bitcoin, is dissimilar to other listed financial instruments per the definition insofar as it is more properly construed on the facts as a real right, rather than a complex of personal rights, involving an issuer and a holder. Moreover in the context of Bitcoin, the indispensable process known as ‘mining' gives rise to the creation of a real right within the ambit of the intended operation of the CGT regime, as well as transactional receipts/accruals from counterparties. Guidance issued by the South African tax authority for how Bitcoin mining is to be treated implies that it always gives rise to a tax event under the normal tax regimerealization immediately upon accrual. This research examines this contention, and demonstrates that there is nothing inherent in Bitcoin mining which satisfies the jurisprudential test for ‘not of a capital nature'; as such it may be dealt with under either regimes without any basis in law for deferment. Nevertheless, a legal analysis of a technological nuance born out of the practicality that mining is a computational race demonstrates the constitution of a partnership arrangement, or an exchange contract for services, particularly in the case of hobbyist miners, or those likely lacking a trade intention. The inescapable effect is that taxation under the normal tax regime is compelled; the respective tax provisions negate any consideration of taxpayer intention. Counterintuitively, a commercial miner, who in fact has a trade intention, enjoys the possibility of taxation under either regime in principle. In a sense this leads to a violation of the neutrality principle in that there is a trade-off between preferential tax consequences and economic efficiency in conducting fundamentally the same activity. The research recommends that the tax legislation should be amended so as to provide for a common, neutral treatment of Bitcoin mining, by which tax is collected immediately under the CGT regime in all cases, while preserving the rights of the state to tax under the normal tax regime in appropriate circumstances to ensure indifference between the current treatment suggested by the tax authority and the proposed treatment, in nominal terms. The interests of the state and taxpayer are thus balanced in accelerating cash flow for the state in exchange for the provision of tax relief for taxpayers who inadvertently fail to appreciate the legal consequences of different mining methods, and/or genuinely have no intention to trade. Universally, it leads to greater legal certainty through a simplification of the tax treatment by disregarding all the nuances which lead to differing results.
