The Construction Site PE
A building, construction, assembly or installation project is a permanent establishment trigger under Article 14 of Federal Decree-Law No. 47 of 2022. The catch is the clock: the number of months that actually creates a PE is usually fixed by the double-tax treaty between the UAE and the contractor's home country, commonly somewhere between 6 and 12 months. Supervisory work on the site counts toward the time. Check the specific treaty before you conclude either way.

The site file starts before the first pour
Article 14 of Federal Decree-Law No. 47 of 2022 names a building, construction, assembly or installation project as a PE route. The question is not limited to the day physical construction begins. Mobilisation, site preparation, installation supervision and the work described in the project contract may all matter to the period and the activity under review.
For a foreign contractor, the decisive document is the UAE project file beside the applicable UAE treaty. Read the project scope, notice to proceed, site access records, progress certificates and handover material as one timeline. If the contractor waits until the site closes to ask the question, some of the evidence that establishes the starting point may already be scattered across subcontractors.
The FTA's Permanent Establishment page treats a building site as a fixed-place PE example and places a duration notation beside it. The exact rule for a cross-border project still depends on the treaty text and the facts. Use the matrix below to keep the clock tied to records rather than an estimate from the project manager.
| Project event | Record to keep | Why it matters |
|---|---|---|
| Mobilisation | Notice to proceed and access log | May establish the first UAE activity |
| Construction or installation | Site diary and progress certificate | Shows the work actually performed |
| Supervision | Timesheets and inspection reports | Shows connected activity beyond physical works |
| Handover or demobilisation | Completion certificate and final invoice | Supports the end of the project period |
A project is more than the finished structure
The statutory wording covers building, construction, assembly and installation. That reaches an engineering or equipment contractor whose UAE obligation is to assemble and commission a system, not only a civil contractor laying foundations. The contract schedule, method statement and commissioning report should therefore be read together. A narrow description such as supply only cannot settle a mixed supply-and-install arrangement. The signed scope of work is the object that tests the label against the work delivered. The same review applies to a specialist installing equipment inside a larger project.
Supervisory work connected with the project needs a place in the file. Keep the supervisor's timesheets, inspection reports, variation approvals and travel-linked site records. The question is not whether every person on the payroll stayed in the UAE. It is whether the foreign business was performing project work through the site and how that activity fits the applicable PE wording.
The contractor should also separate the UAE project from remote design, procurement and head-office work. The general ledger, subcontractor invoices, payroll allocation and project cost report make that division visible. Without that split, a later profit attribution exercise becomes a debate about totals rather than a calculation tied to the work that produced them.
The applicable agreement supplies the missing detail
There is no sound universal month number to copy into every project file. The treaty between the UAE and the contractor's home country may set the duration test and may use wording that differs from another agreement. Start with the treaty PDF from the Ministry of Finance's International Treaties Dashboard, then read the PE article beside the project scope and the time records.
This is the boundary of the evidence, and it is real. Article 14 identifies the project category, while the FTA page gives a practical PE outline, but neither document answers every treaty-specific duration question for you. A project that is safe under one treaty cannot be declared safe under another because its site programme looks similar.
If the project has pauses, extensions or separate work packages, record each event with a reason and supporting document. A shutdown for a commercial dispute is not the same object as demobilisation. A renewed work order is not automatically a new project. The contract history and the site record should explain why the clock did or did not continue.
Count from the objects, then test the result
Ask the contractor for the signed main contract, every variation, the notice to proceed, site access records, daily diaries, supervisor timesheets, progress certificates and the completion file. Add the UAE treaty selected for the contractor's residence. These are the objects that let an adviser test duration, connected supervision and the identity of the business performing the work.
Next, build a single chronology. Put mobilisation, first work, pauses, extensions, parallel work packages and handover on it. Tie each entry to an invoice, diary page, access record or certificate. Then identify the profit attributable to the UAE project in the ledger. A site-duration conclusion without a profit file leaves the client knowing there may be a PE but not what must be reported.
If your site is active now, address the question at the next contract review rather than after handover. The decision is most useful while the project manager can still retrieve the records and while the commercial team can see which scope creates the exposure. The site clock is a tax control, not an item to reconstruct from memory.
A PE finding needs an attribution worksheet
A project PE does not make every foreign-company receipt UAE taxable by label. The FTA's non-resident guidance points to income attributable to a PE, so the contractor needs a working paper that separates UAE project revenue, project costs, shared costs and the profit attributable to the site. The treaty may affect the result, but it does not remove the need for a defensible ledger.
For the tax-rate arithmetic, the FTA General Corporate Tax Guide uses taxable income of AED 6,000,000. AED 375,000 at 0% produces AED 0, and AED 6,000,000 minus AED 375,000 leaves AED 5,625,000. Applying 9% to AED 5,625,000 gives AED 506,250. Treat this as the published rate example, then replace the input with the attributable project figure.
We would not wait for the completion certificate before opening the PE file, because the notice to proceed, access log and early invoices can establish the part of the timeline that later becomes disputed. If the treaty result is uncertain, record that uncertainty and obtain the exact agreement text instead of importing a duration from a different contractor's project.
Frequently Asked Questions
For foreign contractors and EPC firms working in the UAE.
When does a construction site become a UAE PE?
When the project runs past the duration threshold in the applicable double-tax treaty. Article 14 lists the site as a trigger, but the number of months that counts is usually set by the treaty between the UAE and the contractor's home country, commonly 6 to 12 months.
Is there a single domestic time limit?
The operative month threshold generally comes from the relevant tax treaty rather than a single domestic figure. That is why the same nine-month project can be a PE under one treaty and not under another. Always check the specific treaty.
Does supervision on site count toward the time?
Yes. Supervisory activities connected with the building or installation work generally count toward the duration threshold, not just the physical construction itself.
Can we split a contract to stay under the threshold?
Splitting a single project into shorter contracts rarely defeats the test. Related-party work on the same site can be aggregated, and tax authorities look at the project as a whole.
What tax applies once the site is a PE?
The profit attributable to the UAE project is taxed at 9% above AED 375,000, and the PE must register with the Federal Tax Authority and file a return. Treaty relief may still apply to how the profit is allocated.
Can Exiloz assess our site's PE risk?
Yes. We count the project duration against the relevant treaty threshold, factor in supervision and related-party work, and tell you whether the site creates a UAE PE.
Does your site create a PE?
Exiloz counts your project duration against the relevant treaty and flags PE and filing obligations.
