The decision in H.P. Gauff Ingenieure GmbH & Co KG v Commissioner of Domestic Taxes raises a fundamental question for businesses operating across borders: when can income earned outside Kenya still fall within the Kenyan tax net? In addressing this question, the Tax Appeals Tribunal provides important guidance on the interplay between source of income, management and control, and the evidentiary burden placed on taxpayers challenging assessments.

The dispute arose from tax assessments issued by the Kenya Revenue Authority amounting to approximately KES 1.9 billion against a foreign engineering consultancy firm engaged in infrastructure and development projects, some of which were donor-funded and executed outside Kenya. The Commissioner’s position was that, notwithstanding the location of project execution, the income remained taxable in Kenya on the basis that the management and control of the Appellant’s business was exercised within the jurisdiction. The Appellant disputed this position, arguing that the income was sourced outside Kenya and that certain donor-funded projects were exempt from taxation.

In resolving the dispute, the Tribunal moved beyond a purely geographical understanding of income generation and instead interrogated the locus of control. It held that the mere fact that services are performed outside Kenya does not, in itself, preclude taxation. Where it is demonstrated that the strategic and operational control of a business is exercised in Kenya, income may properly be deemed to accrue or derive within Kenya for tax purposes. This approach reflects a broader shift toward substance in determining tax liability, particularly in the context of multinational operations where functions, decision-making, and execution are often spread across jurisdictions.

The Tribunal also addressed the Appellant’s reliance on donor funding as a basis for exemption. It rejected the proposition that donor-funded projects automatically attract tax relief, emphasizing that exemptions must be expressly granted within the legal framework and properly supported by documentation. In the absence of clear statutory backing or formal exemption instruments, a taxpayer cannot rely on the mere nature of funding to avoid tax liability. The decision reinforces the principle that tax exemptions are strictly construed and must be clearly established.

Central to the Tribunal’s determination was the issue of burden of proof. Reaffirming the statutory position, the Tribunal held that the taxpayer bears the responsibility of demonstrating that an assessment is excessive or incorrect. This requires more than assertions; it demands cogent evidence capable of displacing the Commissioner’s findings. In this case, the Appellant failed to provide sufficient documentation and analysis to support its position on both the source of income and entitlement to exemption.

The Tribunal further found that the Commissioner had acted within its mandate in issuing the assessments, having relied on financial and operational indicators pointing to Kenyan-based control of the Appellant’s activities. In the absence of compelling evidence to the contrary, the assessments were upheld.

Ultimately, the appeal was dismissed, and the tax demand sustained. The Tribunal concluded that the income in question was taxable in Kenya due to the locus of management and control, that no valid exemption had been established in respect of the donor-funded projects, and that the Appellant had failed to discharge the burden of proof required to challenge the assessments.

This decision carries significant implications for businesses operating in Kenya, particularly those engaged in cross-border or donor-funded projects. First, it underscores that the concept of “source of income” is not confined to the physical location where services are performed, but extends to where key decisions and control functions are exercised. Second, it reinforces that tax exemptions are not presumed and must be clearly grounded in law and supported by proper documentation. Third, it highlights the critical importance of evidentiary preparedness in tax disputes, as failure to substantiate claims will invariably result in the upholding of assessments.

If your business has cross-border operations, donor-funded projects, or a substantive management presence in Kenya, this ruling makes it a timely moment to review your tax position and ensure your documentation is in order.
