Article 14 defines when a Non-Resident Person has a 'Permanent Establishment' (PE) in the UAE, triggering tax liability on attributable income. A PE can be a fixed place of business (e.g., branch, office, factory) or an agent who habitually exercises authority to conclude contracts on behalf of the non-resident. The article lists exceptions for activities of a preparatory or auxiliary nature, such as storage or purchasing. However, these exceptions do not apply if activities are fragmented to avoid creating a PE. The article also provides rules for dependent versus independent agents, crucial for determining PE status.
