The 2025 OECD Model Convention Update on the International Taxation concept of Permanent Establishments(PE) has fundamentally redefined Human Capital and Workforce Management in the context of cross-border remote working.
These changes, which African nations like Uganda are expected to localise as domestic tax law, widens cross-border tax risk exposure for Multi-National Enterprises(MNEs) beyond commercial presence through physical offices. The news rules recognise the notion of commercial presence through human capital and remote workers working from a home or a similar place in another jurisdiction.
This opinion critically analyses the PE concept and its application to cross-border remote working in the context of Uganda’s current PE law, and further discusses the likely implications of the update from two perspectives:
First, the implications for global and regional firms and technology start-ups scaling across borders, with emphasis on emerging human capital management complications likely to arise once African countries, including Uganda, localise the update into domestic tax law.
Secondly, the opinion discusses the advantages it offers to tax administrations(OECD Member nations and nations that eventually localise the update into domestic law), particularly on combating tax avoidance by multinational enterprises (MNEs).
For the non-technical readers, I will be returning to explain the concept of a PE in simple terms but below are the new changes in brief:
The New Test: A PE is now strongly indicated if an employee works from a home office in State A for 50% of their total working time for their Non-Resident employer in State B AND there is a commercial reason for their presence in state A (e.g, servicing local clients and time-zone alignment). The changes have explicitly rejected cost saving or employee convenience as sole justification for remote cross-border working.
Impact on Tax Administration: The update is a powerful anti-avoidance tool for Tax Authorities, allowing them to assert taxing rights based on functional substance rather than just legal form(e.g work-from-anywhere contract clauses permitting cross-border remote working), materially expanding the tax base beyond the current 183-day Service PE rule.
Headache for MNEs and Tech Start-ups: The new rules transform low-cost, agile market testing for tech start-ups into a high-cost compliance burden for start-ups and other regional businesses trying to enter new markets and to scale across-borders.
The rules will likely result in immediate, non-negotiable Payroll, Social Security, and Immigration risk above Corporate Income Tax, aggressively eroding the limited cash runway of young scaling companies, and rope companies into a more complex compliance matrix.
