A foreign company with a Permanent Establishment (PE) in the UAE is subject to UAE CT at 9% on income attributable to that PE. A PE exists when there is a fixed place of business in the UAE (office, project site, warehouse), a dependent agent who habitually concludes contracts in the UAE, or a construction project running for more than 6 or 12 months (depending on applicable treaty). Double tax treaties can modify these thresholds.
What is a Permanent Establishment under UAE CT?
A Permanent Establishment (PE) is a fixed place of business through which a non-UAE resident conducts all or part of its business in the UAE. Once a PE is established, the foreign company becomes a UAE taxable person in respect of the income attributable to that PE.
UAE CT follows the OECD model for PE definition, which is also used in most of UAE’s 100+ double tax treaties. The three key PE triggers are: (1) fixed place of business; (2) dependent agent; and (3) construction or installation project.
What triggers a UAE PE?
A foreign company that only maintains a UAE bank account, holds UAE investments through a nominee, or has a UAE post office box does not automatically have a PE. PE requires active business operations. However, using a UAE-resident employee to negotiate and conclude contracts — even from a home office — can create a dependent agent PE.
| PE type | Trigger | Threshold |
|---|---|---|
| Fixed place of business | Office, branch, factory, workshop, mine, store | No minimum duration — exists from day one |
| Server/equipment | UAE-based servers or equipment used in business | Depends on treaty; UAE domestic rule: any server used commercially |
| Construction PE | Building, construction, assembly, installation project | 6 months (most treaties) or 12 months (some treaties) continuous |
| Dependent agent | Person who habitually concludes contracts for the foreign company in UAE | No specific day threshold — habitual is the test |
| Substantial presence | Management or employees present in UAE for core business decisions | 183 days in a 12-month period |
Treaty protection — how double tax treaties limit PE exposure
If the foreign company’s home country has a double tax treaty with the UAE, the treaty PE definition applies rather than domestic UAE rules. Treaties typically raise PE thresholds — e.g., a construction project PE threshold of 12 months rather than 6, or a specific exclusion for preparatory and auxiliary activities.
Treaty PE articles also typically exclude: the use of facilities solely for storage or display of goods, maintaining a stock of goods solely for delivery, purchasing goods, collecting information. These preparatory and auxiliary activities do not create a PE even if conducted at a fixed UAE location.
UAE has bilateral treaties with 100+ countries, and they vary significantly. The UAE-India treaty uses a 9-month construction threshold; UAE-UK uses 12 months; UAE-Germany uses 12 months with broader auxiliary exceptions. Always check the specific treaty for the foreign company’s home country.
Attribution of income to a UAE PE
Once a PE exists, only the income attributable to the PE is subject to UAE CT — not the foreign company’s global income. Attribution follows the OECD authorised approach: the PE is treated as a separate enterprise dealing at arm’s length with the rest of the foreign company.
In practice, a UAE project office that manages a construction contract is assessed on the profit of that contract — revenue attributable to UAE work minus costs directly associated with the UAE activity, including a reasonable allocation of head office overhead at arm’s length rates.

Frequently asked questions
Does a foreign company pay UAE Corporate Tax?+
A foreign company pays UAE CT at 9% on income attributable to a UAE Permanent Establishment (PE). Without a UAE PE, a foreign company is generally not subject to UAE CT (though withholding tax rules may apply in future regulations).
What creates a Permanent Establishment in UAE?+
Three main triggers: (1) a fixed place of business — office, branch, workshop, server; (2) a dependent agent who habitually concludes contracts in the UAE; or (3) a construction/installation project exceeding 6 or 12 months (depending on applicable tax treaty).
Does a construction project in UAE create a Corporate Tax liability?+
Yes, if the project runs beyond the PE threshold in the applicable treaty (typically 6–12 months). Once the threshold is crossed, the project creates a PE from day one — not from the day the threshold is reached. All project income is then attributable to the UAE PE.
Can a double tax treaty prevent UAE CT on a foreign company?+
A treaty can raise the PE thresholds (e.g., 12-month construction rule vs 6-month domestic rule) or exclude preparatory/auxiliary activities. But if a treaty PE exists, the foreign company owes UAE CT on attributable income — treaties allocate taxing rights, they do not eliminate them.
How is income attributed to a UAE PE for CT purposes?+
The PE is treated as a separate entity dealing at arm’s length with the rest of the foreign company. Revenue from UAE activities minus directly attributable costs, plus a reasonable head office overhead allocation, gives the PE’s taxable profit. UAE CT at 9% applies on income above AED 375,000.
Must a foreign company with a UAE PE register for CT?+
Yes. A foreign company with a UAE PE must register for UAE CT on EmaraTax, file a CT 300 return, and pay CT within the standard 9-month deadline. A registered branch counts as a PE and its registration on EmaraTax automatically triggers CT registration obligations.
