Residency and Permanent Establishment Status of EACOP Ltd Across the Project States
Part 1 laid out the underlying rules: how tax residency is determined, how “tie-breaker” tests resolve competing residency claims, and how permanent establishment (PE) status is worked out when a business, especially a pipeline, operates across borders. This part applies those rules to the actual company at the centre of the project, EACOP Ltd, across the three states with a stake in its tax treatment: the United Kingdom, where the company is incorporated; Uganda, where its management sits; and Tanzania, where the pipeline exits to port.
1. The United Kingdom
a. Is EACOP Ltd a UK Tax Resident?
Under UK domestic law, incorporation alone normally settles the question. Section 14(1) of the UK Corporation Tax Act 2009 provides that a company incorporated in the United Kingdom is UK resident, for corporation tax purposes. Section 14(2) goes further and effectively locks that conclusion in place: even if some other legal rule would point to a different country as the company’s residence, UK law still treats it as UK resident regardless.
On its face, this creates a direct collision with EACOP’s own governing framework. EACOP Ltd is incorporated in England and Wales, but under the intergovernmental “agreed fiscal regime” negotiated for the project as contained in the EACOP (Special Provisions) Act (EACOP Act), it is designated a Ugandan tax resident, on the basis that its management and control are exercised in Uganda. Read literally, sections 14(1) and 14(2) would seem to override that designation and claim EACOP Ltd as a UK resident regardless of what the project agreements say.
That collision, however, doesn’t actually happen, because UK law builds in an escape hatch precisely for this situation. Section 18 of the CTA 2009 provides that even where a company would otherwise be UK resident purely by virtue of incorporation, it will be treated as resident outside the UK where a double taxation treaty says so. This is where the Uganda–UK Income Tax Treaty does the real work: Article 4(3) applies the standard international tie-breaker, providing that where a non-individual entity is a resident of both contracting states, its treaty residence follows its place of effective management. Since EACOP Ltd’s effective management is, by design, exercised in Uganda under the terms of the Uganda EACOP Act, the treaty tie-breaker resolves the question in Uganda’s favour.
The net result is that UK domestic law, the Uganda–UK tax treaty, and the project’s own agreed fiscal regime all point the same direction: EACOP Ltd is a tax resident of Uganda, not the United Kingdom, notwithstanding its English incorporation.
b. Does EACOP Ltd Have a UK Permanent Establishment?
Having settled that EACOP Ltd is a non-resident in the UK, the next question is whether it nonetheless has a taxable presence there through a PE. Section 1141 of the UK Corporation Tax Act 2010 applies the familiar test: a company has a PE in a UK territory if, and only if, it has a fixed place of business there through which its business is wholly or partly carried on, with offices and branches given as illustrative examples of what counts as a fixed place.
EACOP Ltd does maintain a registered office in the UK. On a superficial reading, an office is exactly the kind of fixed place the test contemplates, which might suggest a UK PE exists. But the test has a second, decisive limb: the company’s actual business must be carried on through that place. EACOP Ltd’s entire commercial function is the transportation of crude oil through the physical pipeline system running across Uganda and Tanzania, not anything happening at a London registered-office address. A registered office used for corporate formalities, without the substantive transportation business being conducted through it, does not satisfy the “carrying on business through that place” limb. On that basis, EACOP Ltd should not be treated as having a PE in the UK.
Curiously, the project’s own agreed fiscal regime describes the UK office as a “UK PE” regardless. This appears to be more a matter of cautious or imprecise drafting than a substantive tax conclusion, since no meaningful business activity or profit-generating function is actually performed from London, the label carries little practical consequence: there would be no profit to attribute to a UK PE even if the label is taken literally, because attribution follows function, not description.
2. Uganda
a. Is EACOP Ltd a Ugandan Tax Resident?
Uganda’s domestic residency test, under section 10 of the Uganda Income Tax Act, is written broadly and disjunctively: a company is a Ugandan resident company for a year of income if it is incorporated or formed under Ugandan law, or has its management and control exercised in Uganda at any time during the year, or undertakes the majority of its operations in Uganda during the year. Only one of these three limbs needs to be satisfied.
EACOP Ltd doesn’t meet the first limb, it’s incorporated in England and Wales, not Uganda. But it squarely meets the second: under the EACOP Act and the project’s agreed fiscal regime, effective management and control of the company are exercised in Uganda. That alone is sufficient to make EACOP Ltd a Ugandan tax resident under ordinary domestic law, entirely independent of the treaty tie-breaker analysis. In other words, Uganda’s claim to be EACOP Ltd’s home tax jurisdiction doesn’t depend on winning an international tie-break, it follows straightforwardly from Uganda’s own statute, and that outcome is consistent with both the Uganda–UK treaty analysis above and the project’s own agreed terms.
b. Permanent Establishment in Uganda
Because EACOP Ltd is already established as a Ugandan resident taxed on its worldwide income there, the question of whether it separately has a PE in Uganda becomes largely academic for EACOP Ltd itself, a resident company doesn’t need PE status to be taxable in its own home jurisdiction.
That said, it’s worth noting that Uganda’s PE rules have themselves been substantially modernised since the project’s fiscal framework was first negotiated. Uganda’s Income Tax (Amendment) Act, 2024, which took effect on 1 July 2024, repealed the old, narrower “branch” concept that Uganda’s tax law previously relied on and replaced it, throughout the international taxation provisions of the Act, with a detailed “permanent establishment” definition closely modelled on the OECD and UN approaches. The new provision lists the familiar fixed-place example, a place of management, a branch, an office, a factory, a workshop, a warehouse used to store goods for others, a mine, an oil or gas well, a sales outlet, and adds specific time-based thresholds: a construction, installation, or assembly project (or related supervisory activity) becomes a PE once it runs for at least ninety days in any twelve-month period; the furnishing of services becomes a PE once it continues for 183 days or more in any twelve-month period; and the use of substantial equipment or machinery becomes a PE once it is operated, or available for operation, for ninety days or more.
The 2024 amendment also imported two more technical protections against avoidance that mirror recent international developments discussed in Part 1: an anti-fragmentation rule, which prevents a business from escaping PE status by splitting a single cohesive operation into smaller activities carried out by associated persons at the same or connected places, and a dependent-agent PE rule, under which a non-resident is deemed to have a Ugandan PE where someone habitually concludes contracts, or plays the principal role in securing them, on that non-resident’s behalf, unless that agent is genuinely independent and acting in the ordinary course of its own business. A companion provision, also inserted in 2024, sets out how a Ugandan PE’s chargeable income is to be calculated: broadly on a separate-entity basis, with specific restrictions on deducting royalties, management fees, or interest paid by the PE to its own head office, other than in the case of financial institutions. (This is discussed in detail in another blog specific to PEs, ‘Permanent Establishment Under Uganda’s Income Tax Act post 2024:What Changed, and Why It Matters)
None of this changes EACOP Ltd’s own position, since its Ugandan tax liability rests on residency rather than PE status. But the modernised regime is directly relevant to the wider ecosystem of contractors, subcontractors, and service providers engaged on the Ugandan side of the project, for whom construction-period and service-related PE exposure is now assessed under a considerably more detailed and OECD-aligned standard than existed when the project’s fiscal framework was first agreed.
3. Tanzania
a. Is EACOP Ltd a Tanzanian Tax Resident?
Tanzania’s residency test, under section 66(4) of the Tanzania Income Tax Act, mirrors Uganda’s core logic on incorporation and management: a corporation is Tanzania-resident if it is incorporated or formed under Tanzanian law, or if its management and control are exercised in Tanzania at any time during the year of income. On a straightforward reading, EACOP Ltd fails both limbs, it is incorporated in England and Wales, and its management and control are exercised in Uganda, not Tanzania, which would suggest EACOP Ltd is a non-resident in Tanzania.
Tanzanian case law complicates this straightforward reading, however. In Tanzania v African Barrick Gold PLC, the Tanzanian Court of Appeal considered a foreign-incorporated company that had registered locally and been issued a certificate of compliance under the Companies Act. The court held that this registration was itself sufficient for the company to be treated as “formed” in Tanzania, because Tanzania’s Income Tax Act defines “corporation” to include entities incorporated anywhere, including outside Tanzania, and therefore a tax resident under the “formed” limb of the residency test, independent of where its management actually sat. Since EACOP Ltd is itself registered in Tanzania (as a foreign company, through the standard local registration process), this precedent, taken at face value, would arguably make EACOP Ltd a Tanzanian tax resident too, alongside its Ugandan residency, potentially reviving exactly the kind of dual-residency conflict discussed in Part 1.
This decision has drawn sharp criticism from tax commentators, one of whom described it as a particularly troubling example of a poorly reasoned tax ruling, on the basis that it stretches the ordinary meaning of “formed” well beyond what the residency test was designed to capture, collapsing it into mere local registration. This write up shares that scepticism and does not treat African Barrick Gold as a sound basis for evaluating EACOP’s residency position. In practice, the point is resolved by the project’s own legal architecture rather than by litigating the merits of that case: the agreed fiscal regime expressly provides that EACOP Ltd is resident in Uganda for tax purposes and non-resident in Tanzania, an outcome that aligns with the orthodox, internationally accepted approach to corporate residency (incorporation or genuine management and control), rather than the more expansive reading adopted in African Barrick Gold.
b. Permanent Establishment in Tanzania
Tanzania’s Income Tax Act defines a permanent establishment simply as a place where a person carries on business. Here, the analysis is far less contested. The EACOP pipeline physically runs through Tanzanian territory, and the project includes dedicated offices and facilities at the export terminal in Tanga. EACOP Ltd’s core commercial activity, providing crude oil transportation services, is therefore self-evidently being carried on through a fixed place in Tanzania.
This is also where the Article 5(4) analysis from Part 1 becomes concrete rather than theoretical. EACOP Ltd is not simply moving its own oil through Tanzania; it is a dedicated transportation company carrying crude belonging to the upstream oil companies with production interests in Uganda’s oil fields. That is precisely the fact pattern in which the “delivery of goods” and “preparatory or auxiliary” exceptions fail, and a PE is expected to arise. Consistent with that analysis, the project’s agreed fiscal regime confirms that EACOP Ltd is to be treated, for tax purposes, as having a permanent establishment in Tanzania, an outcome that tracks the underlying international tax principles rather than departing from them.
4. Where This Leaves EACOP Ltd
Pulling the three jurisdictions together: EACOP Ltd has no permanent establishment in the United Kingdom despite its English incorporation and London registered office; it is a full tax resident of Uganda, both under ordinary domestic law and under the UK treaty tie-breaker, with the question of a separate Ugandan PE rendered moot by that residency; and it is a non-resident of Tanzania that nonetheless has a permanent establishment there, created by the pipeline and port infrastructure through which its transportation business is actually carried on.
That configuration, head office and full tax residency in Uganda, a permanent establishment in Tanzania, sets up the next, and arguably more consequential, question: how much of EACOP Ltd’s profit should actually be attributed to Uganda as the residence state, and how much to Tanzania as the state hosting the PE. That is the subject of Part 3.
Part 3 will examine how the agreed fiscal regime attributes profit between EACOP Ltd’s Ugandan head office and its Tanzanian permanent establishment, and how well that attribution mechanism holds up against the international profit-attribution standards discussed in Part 1.
