Abstract

Labour, in all its dimensions, has been "on the move" in the last few years. Before the pandemic, labour mobility has mostly interested only a fraction of the working population, such as highly skilled and high-net-worth individuals. COVID-19 has, however, expanded the extent of labour mobility and the categories of workers involved. This contribution discusses four major changes in labour patterns: (i) home office work; (ii) non-standard forms of employment; (iii) digital nomadism; and (iv) the decentralization of jobs. In particular, the article illustrates how a "work-from-anywhere" scenario may impact the taxation of labour income under tax treaties. Using mainly the OECD Model as a reference, the article discusses difficulties related to the application of physical presence as a sourcing rule for employment income, the distinction between dependent and self-employment income, and the concepts of home office and fixed base. Based on the analysis provided, the author formulates tentative proposals for reforming the current tax treaty treatment of labour income. Specific recommendations include the introduction of a new article jointly dealing with the taxation of labour income, a reviewed scope of application of the physical presence criterion and tax treaty definitions of home office and fixed base.

... It is clear from the wording of Article 15 (1) and (2) of the OECD ICC that the place of work is crucial. It is where the work is performed that determines where the employee's income is taxed unless Article 15(2) of the OECD Model Convention applies (Beretta, 2022). How is this concept to be understood? ...

Digital nomads are a new generation of workers who go beyond traditional organisational boundaries, bringing disruptive business models to various industries with different work cultures and valuing different types of capital. Although work mobility is not a new concept, it has gained significant support after the COVID-19 pandemic, with many people starting to work remotely and this reflecting on their lifestyles. In this context, the aim of the study is to analyse the challenges faced by digital nomads from an individual taxation perspective and within the framework of international taxation principles. Based on the analysis of examples and the presentation of some alternatives, this paper considers proposals for amending the Model Agreements” rules on the taxation of income from employment and the provision of independent services to remove the strict requirement of physical presence

Pistone, supra n. 105, at sec. 3.3.2.4. Indeed, some tax treaties already extend this provision to railway and road transportation workers (see, e.g., art. 15(3) Belg.-Lux. Income and Capital Tax Treaty (17 Sept. 1970), Treaties & Models IBFD). Although teleologically acceptable as a proposal, as Pistone also acknowledges, the definition of "mobile worker" appears quite problematic, especially considering a large-scale "work-from-anywhere" scenario in which potentially a high number of workers can move across different countries.
