Introduction

For decades, if you asked a Ugandan tax practitioner how the law taxed a foreign company doing business in Uganda, the answer began with one word: “branch.” Since 1 July 2024, that word has effectively left the statute book. In its place, the Income Tax (Amendment) Act, 2024 introduced a new Section 77A, replacing the domestic concept of a “branch” with the internationally recognised concept of a “permanent establishment” (PE) the same term used in Uganda’s double taxation agreements (DTAs) and in the OECD and UN Model Tax Conventions.

This is not a cosmetic rebrand. It changes what counts as a taxable presence in Uganda, narrows some of the old ambiguity, widens the net in other respects, and brings entirely new anti-avoidance machinery into Ugandan domestic law for the first time. This piece walks through what the PE concept actually does, what the law said before, what changed, and what it means in practice for businesses operating in or into Uganda.

What a Permanent Establishment Actually Does

Before getting into the detail of Section 77A, it helps to be clear on why the PE concept exists at all.

For any country to tax income, there has to be a nexus, a connection between that country and the income in question. A state can establish nexus in one of two ways: through the person earning the income (typically via tax residence), or through the income itself (typically via its source). A nexus to the person supports comprehensive taxation of that person’s worldwide income; a nexus to income only supports a narrower, source-based right to tax.

A person is usually fully taxable in their state of residence. But where that person carries on activities in another state, the “source” state international tax rules apply a threshold test to decide whether those activities are substantial enough for the source state to claim a right to tax them too. That threshold is the permanent establishment. Once a PE is recognised, the source country gains the right to tax the profits attributable to it, generally determined by applying arm’s length principles as if the PE were an independent entity dealing with the rest of the enterprise at arm’s length.

Get the PE analysis wrong, in either direction, and the consequences are real: a business that inadvertently creates a PE faces unexpected registration, filing, and tax obligations in a jurisdiction it didn’t think it had a taxable footprint in; a source country that defines PE too narrowly loses out on tax revenue from real economic activity happening within its borders.

Before July 2024: The "Branch" Era Under Section 78

Prior to the 2024/2025 amendments, Uganda didn’t use the term “permanent establishment” in its domestic law at all. Instead, Section 78(a) of the Income Tax Act defined a “branch” as a place where a person carries on business, and this was interpreted to include an agency branch, a construction or project branch, the furnishing of services (including consultancy services), and a place where a person had, used, or installed substantial equipment or machinery for ninety days or more.

Functionally, “branch” was doing the same job the PE concept does elsewhere but the drafting had two structural weaknesses:

  • It spoke a different language from Uganda’s own treaties. Every one of Uganda’s DTAs, being based on the OECD or UN Model Conventions, uses “permanent establishment,” not “branch.” Having two different terms for what was meant to be the same underlying concept created real scope for argument about whether the domestic and treaty tests lined up.
  • It was thin on detail. The old Section 78(a) was a short, general definition rather than a structured, itemised test. That left a lot to be filled in by reference to treaty law and international commentary, workable for tax specialists, but an unpredictable starting point for taxpayers trying to self-assess their exposure.

The Reform: Section 77A and the Arrival of the PE Standard

The Income Tax (Amendment) Act, 2024 repealed the “branch” definition and replaced it, through the new Section 77A, with a permanent establishment test that closely follows Article 5 of the OECD and UN Model Tax Conventions, with a number of Uganda-specific modifications. Section 77A(1) now defines a PE as “a fixed place of business through which the business of the enterprise is wholly or partly carried on” language lifted almost verbatim from Article 5(1) of both Model Conventions  before going on to itemise an expanded, more prescriptive list of what that includes.

A companion provision, Section 77B, addresses a question the old law never really engaged with: once you have a PE, how do you work out how much profit belongs to it? We come back to this below.

What Changed, Concretely

A longer list of deemed permanent establishments

Where the old Section 78(a) listed only a handful of categories, Section 77A’s list now reads much closer to the OECD/UN template: a place of management, a branch, an office, a factory, a workshop, a warehouse used to provide storage facilities to others, a mine, oil or gas well, quarry, or other place of natural resource extraction, a farm, plantation, or other place where forestry or agricultural activities are carried on, and a sales outlet. Warehouses, farms/plantations, and sales outlets in particular are new additions with no clear counterpart in the old branch definition, a direct expansion of the categories of physical presence that can now trigger a taxable footprint in Uganda.

Construction and installation projects: same 90-day trigger, tighter drafting

Both the old and new law set the threshold for a construction, installation, or assembly project (including related supervisory activity) at ninety days or more within a twelve-month period. The number hasn’t moved, but it’s worth noting how it compares internationally: the OECD Model Convention sets this threshold at twelve months, and the UN Model at six months. Uganda’s ninety-day trigger is markedly shorter than either, meaning Uganda’s domestic law is, and was already, considerably more aggressive than the international models on construction-site PEs.

Service PEs: the threshold actually lengthened — but the reach widened

This is one of the more counter-intuitive changes. Under the old Section 78(a), the furnishing of services (including consultancy) created a branch once activity on the same or a connected project exceeded ninety days in aggregate. Under the new Section 77A1(k), that threshold has risen to 183 days or more within any twelve-month period bringing Uganda’s rule into line with the services-PE provision found in the UN Model Tax Convention (which the OECD Model does not include as core text). Taken in isolation, that’s a higher bar for triggering a services PE. But read alongside the broader definitional expansion, the anti-fragmentation rule, and the more detailed agency test discussed below, the overall effect of the reform is still to widen, not narrow, Uganda’s tax net, the services threshold is simply the one place where the new law is more taxpayer-friendly than the old.

Equipment and machinery: unchanged at 90 days

The rule that substantial equipment or machinery operated, or available for operation, in Uganda for ninety days or more (in any twelve-month period) creates a PE carries over from the old law essentially unchanged.

A modern, structured agency PE test

The old Section 78(a) gestured at agency PE in a single line, a place where a person carries on business through an agent, “other than a general agent of independent status acting in the ordinary course of business.” Section 77A replaces this with a fuller dependent-agent/independent-agent framework: where a person acts in Uganda on behalf of a principal in ways that meet specified conditions, the principal is deemed to have a PE in Uganda in respect of that agent’s activities unless the agent is genuinely independent and acting in the ordinary course of its own business. This tracks the structure (if not every word) of the modern OECD/UN dependent-agent test, including the OECD’s post-BEPS emphasis on habitually concluding, or habitually playing the principal role in concluding, contracts on the principal’s behalf.

New exclusions for genuinely preparatory or auxiliary activities

For the first time, Ugandan domestic law now expressly carves out activities that should not create a PE, provided they are merely preparatory or auxiliary in character: using facilities solely to store or display goods, maintaining stock solely for storage, display, or processing by another party, maintaining a fixed place of business solely to purchase goods or gather information, and any combination of these. The old law had no equivalent express exclusion at all this is a genuinely new, and generally taxpayer-favourable, feature of the regime, mirroring Article 5(4) of the OECD Model.

The anti-fragmentation rule: closing a real loophole

The preparatory/auxiliary exclusion above comes with an important limitation, also entirely new to Ugandan law: the anti-fragmentation rule. Where the same enterprise, or a closely associated enterprise, carries on business at the same or another place in Uganda, the exclusion will not apply if that other activity itself constitutes a PE, or if the combined activity of both places, taken together, is no longer merely preparatory or auxiliary. In parallel, Section 77A also aggregates the time period of connected activities carried out by associates for the purposes of the day-count thresholds on construction, services, and equipment PEs, so that closely related entities cannot simply split a single project between themselves to keep each slice under the relevant threshold. Neither rule had any real equivalent in the old Section 78, this is new anti-avoidance architecture, adapted from the OECD’s post-BEPS Article 5 update, now sitting in Ugandan domestic law.

Section 77B: Attributing Profit to the PE

Recognising a PE is only half the exercise, the law then has to say how much of the enterprise’s profit is taxable in Uganda. Section 77B addresses this by treating the PE as a distinct and separate entity from the non-resident person of which it forms part, with transactions between the PE and its head office subject to Uganda’s transfer pricing provisions. Deductible expenses are limited to those genuinely incurred for the PE’s own business. Notably, the PE’s gross income specifically excludes notional charges made by the PE to its own head office for royalties, fees, or similar payments for the use of intangibles in other words, a PE cannot manufacture a deduction for itself by “paying” its own head office for the right to use group IP. This mirrors a principle found across the region (Kenya’s PE rules, for instance, apply a similar “single entity” restriction) and means that any PE in Uganda should now expect to need proper transfer pricing documentation to support its reported profit.

How the New Rules Compare to the OECD and UN Models

The headline provision of Section 77A(1) — “a fixed place of business through which the business of the enterprise is wholly or partly carried on” is copied almost word for word from Article 5(1) of both the OECD and UN Model Conventions, as is the illustrative list in Article 5(2). Where Uganda departs from the international models, it generally departs in the direction of a lower threshold for source-country taxation: a 90-day construction-site trigger against the OECD’s twelve months and the UN’s six months, an anti-fragmentation rule modelled on the OECD’s 2017 BEPS-driven update to Article 5, and additional deemed-PE categories (warehouses, farms and plantations, sales outlets) that go beyond the Model Convention list. The services-PE test, at 183 days, is the one area of closer alignment specifically with the UN Model’s approach, which is itself designed with the interests of capital-importing, source-based countries in mind. Taken together, the reform reads less as a wholesale import of the OECD standard and more as a source-country-oriented adaptation of both Models, calibrated to protect Uganda’s revenue base.

Why This Matters in Practice

The stated purpose behind the reform is to align Uganda’s domestic law with international standards particularly the OECD/G20 Base Erosion and Profit Shifting (BEPS) project, and specifically Action 7’s concern with the artificial avoidance of PE status and, in doing so, to widen domestic revenue collection from non-residents whose activities the old “branch” test was not well equipped to capture, especially in services and digital business models.

For businesses with any cross-border footprint in Uganda, this has immediate, practical consequences:

  • Day-count exposure needs active tracking. Any foreign business sending staff, contractors, or consultants into Uganda, or operating equipment there, should be tracking cumulative days against the relevant 90-day or 183-day thresholds including days spent by associated entities on connected projects, which are now aggregated.
  • Agency arrangements deserve a fresh look. Distribution, sales, or representative arrangements that were previously assessed under the old, thinly drafted agency test should be reassessed against the more structured dependent-agent framework in Section 77A.
  • “We’re just a rep office” is a harder argument to sustain. The new preparatory/auxiliary exclusion is real, but the anti-fragmentation rule specifically targets attempts to dress up substantive activity as a collection of individually minor, non-taxable functions.
  • Existing and new PEs need transfer pricing documentation. With Section 77B explicitly invoking the arm’s length and transfer pricing provisions of the Act, and expressly disallowing notional intra-entity royalty or fee deductions, PEs can no longer treat profit attribution as a formality.

A Closing Thought

The shift from “branch” to “permanent establishment” is, on paper, a matter of aligning terminology with Uganda’s treaty network. In substance, it is a considerably more consequential change: an expanded list of deemed PEs, a new anti-fragmentation regime, a modernised agency test, and  through Section 77B  a firmer, transfer-pricing-anchored basis for taxing whatever profit is found to be attributable to a Ugandan PE. The open question every foreign business now has to ask is a practical one: given how much broader and more precisely targeted this new definition is, which of our current activities, arrangements, or personnel deployments in Uganda might now cross the line into a permanent establishment  and are we ready to defend the profit we’d have to attribute to it?
