The Mainland Office That Taxes Your Free Zone Company

The permanent establishment rule is the one that catches growth. A free zone company opens a mainland office to be closer to customers, or puts a small team into another country to serve a region. Neither decision looks like a tax decision. Both can create a permanent establishment, and the income attributed to it is outside the 0% before any qualifying income analysis begins.

Where this sits in the order of analysis

This is worth getting right, because it explains why the rule is easy to miss. Article 3(1) of Cabinet Decision No. 100 of 2023 lists the categories of Qualifying Income, but it opens with a condition: the income qualifies provided it is not attributable to a Domestic Permanent Establishment or a Foreign Permanent Establishment under Article 5, not derived from immovable property under Article 6, and not Taxable Income under Article 7(2).

That distinction matters both ways. A company can be entirely comfortable on its revenue mix and still have a fully taxable slice of income sitting outside that calculation.

The FTA's Free Zone Persons guide takes it one step further, and the step is easy to miss. Revenue attributable to a permanent establishment is excluded from total Revenue as well as from non-qualifying Revenue when the de minimis calculation is performed. Its worked example: a free zone person with AED 10 million of revenue, of which AED 2 million is attributable to a Domestic Permanent Establishment, performs the de minimis test on total Revenue of AED 8 million.

What Article 5 provides

Article 5(1) states that income attributable to a Domestic Permanent Establishment or a Foreign Permanent Establishment of a Qualifying Free Zone Person is Taxable Income, taxed at the standard rate under the Corporate Tax Law.

Article 5(2) sets out how much income that is. For a tax period, the attributable income is the taxable income attributable to the establishment calculated as if the establishment were a separate and independent Person that is a Related Party of the Qualifying Free Zone Person.

Why that wording pulls transfer pricing into a free zone question

"Separate and independent Person that is a Related Party" is the attribution standard, and it turns what looks like a free zone classification issue into a pricing exercise. To work out what the establishment earned, you have to decide what it would have earned dealing with the rest of the company at arm's length — which functions it performs, which assets it uses, which risks it bears.

That has a direct consequence for how a free zone group should think about this. The mainland branch or overseas presence is not simply a cost centre that reduces profit; it is a notional counterparty whose share of the profit is taxable. Understating that share is a transfer pricing position, with the documentation expectations that follow — and transfer pricing compliance is separately a condition of Qualifying Free Zone Person status in its own right.

Domestic and foreign, and why the domestic one is the surprise

A Foreign Permanent Establishment is the familiar concept: a presence in another country substantial enough to be taxable there. Groups expanding out of the UAE usually have it on their radar, if only because the other jurisdiction raises it.

A Domestic Permanent Establishment is the one that surprises people, because it is a permanent establishment of a UAE entity inside the UAE — the mainland presence of a free zone company. Nothing crosses a border, no foreign authority takes an interest, and the arrangement often begins informally: a sales office, a service team stationed at a client site, a warehouse operated outside the zone.

The interaction with substance

There is a tension worth naming. The substance rules require core income-generating activities to be carried on inside the Free Zone or Designated Zone. The permanent establishment rule taxes income attributable to activity carried on outside it.

A company drifting toward a mainland operating model is therefore moving toward two problems at once, not one: attributable income taxed under Article 5, and a weakening substance position on the activity that has moved. They are separate tests, and a company can fail both on the same facts.

What to check

1. Map where people actually work, as opposed to where they are employed and visa-sponsored. Habitual working location is what drives the analysis.
2. Identify any fixed place of business outside the zone — offices, warehouses, sites, long-term client premises — and how long it has been in use.
3. Consider whether anyone outside the zone habitually concludes contracts or plays the principal role in doing so.
4. Where a presence exists, attribute income to it deliberately, on a functional analysis, and document the basis. Article 5(2) requires an arm's length attribution, not a residual.
5. Re-check after any expansion into the mainland or another country, because this is a facts-based test that changes as the business changes.

Whether a Domestic Permanent Establishment exists is determined by reference to the definitions in the Corporate Tax Law. Cabinet Decision No. 100 of 2023 was issued on 25 October 2023 and takes effect from 1 June 2023; it repealed Cabinet Decision No. 55 of 2023. Confirm the position for your own facts before relying on it.
