The UAE's free zones have long been a magnet for mid-market firms seeking tax efficiency and regional access. But as tax residency rules tighten, the classic pass-through structure—where a free zone entity invoices an onshore or offshore affiliate—is coming under fresh scrutiny. This explainer unpacks the regulatory shifts, the commercial drivers, and the practical options for firms navigating the new landscape.
What Changed: The Regulatory Push
The UAE has been steadily aligning its tax framework with international standards. The introduction of corporate tax in 2023 was a watershed, but the more recent focus has been on economic substance and tax residency. The Ministry of Finance and the Federal Tax Authority have clarified that free zone entities must demonstrate genuine economic activity to benefit from the 0% corporate tax rate on qualifying income. Pass-through arrangements that lack substance—where a free zone entity merely invoices on behalf of an onshore or offshore affiliate—are increasingly being challenged.
In parallel, the UAE's tax residency rules have been updated to require individuals and companies to prove a stronger physical and economic presence. For mid-market firms, this means that a free zone entity cannot simply be a mailbox. It must have real employees, real decision-making, and real operations in the free zone. The days of using a free zone entity purely as a pass-through for profits are numbered.
Why It Matters: The Commercial Impact
For mid-market firms, the stakes are high. Free zone entities have been used to channel profits from onshore operations, often to benefit from lower tax rates or to facilitate profit repatriation. With the tightening rules, firms face a choice: either restructure their onshore-offshore flows to meet the new substance requirements, or risk losing the tax benefits and facing penalties.
The commercial impact is twofold. First, there is the direct cost of compliance—hiring local staff, leasing physical office space, and documenting decision-making processes. Second, there is the strategic cost of restructuring. Firms may need to shift profit centres, renegotiate intercompany agreements, or even move operations between free zones and onshore jurisdictions. For mid-market firms with limited resources, these are significant decisions.
Who Is Affected: The Mid-Market Segment
Mid-market firms are particularly exposed. Unlike large multinationals, they often lack the in-house tax expertise to navigate complex restructuring. They may also have less flexibility in relocating operations. The typical affected firm is one that has a free zone entity in, say, Jebel Ali or DMCC, and an onshore entity in mainland Dubai or Abu Dhabi. The free zone entity invoices the onshore entity for services or goods, and the profits accumulate in the free zone.
Under the new rules, such arrangements must be supported by genuine economic activity in the free zone. If the free zone entity has no employees or office, it will not qualify for the 0% rate. This is a direct challenge to the pass-through model.
How Firms Are Responding: Restructuring Options
Firms are adopting several strategies. The first is to 'onshore' the pass-through: convert the free zone entity into a fully operational branch or subsidiary with real substance. This may involve hiring staff, leasing office space, and moving key functions into the free zone. The second is to 'offshore' the pass-through: move the profit centre to a jurisdiction with a more favourable tax regime, such as a holding company in a low-tax jurisdiction. However, this must be done carefully to avoid triggering controlled foreign company rules or anti-avoidance provisions.
A third option is to restructure the intercompany pricing. Instead of a simple pass-through, firms can set up a more defensible transfer pricing policy that reflects the actual functions, assets, and risks of each entity. This requires a detailed functional analysis and documentation, but it can preserve the tax benefits while meeting the substance requirements.
Risks and Unknowns
The main risk is that the UAE authorities will apply the rules retroactively or with unexpected strictness. There is also uncertainty about how the substance requirements will be interpreted in practice. For example, what constitutes 'sufficient' economic activity? The FTA has issued guidance, but there is still grey area. Firms should also be aware that the OECD's Base Erosion and Profit Shifting (BEPS) framework is influencing UAE policy, and further changes are likely.
Another unknown is the interaction with the UAE's economic substance regulations, which were introduced in 2019. These require certain activities to be carried out in the UAE, but the new tax residency rules go further. Firms must ensure they are compliant with both sets of rules, which can be complex.
FY Outlook
In the near term, we expect to see a wave of restructuring as mid-market firms bring their structures into line. This will create demand for tax advisory services, legal restructuring, and HR support. In the medium term, the UAE's free zones may need to adapt their offerings to attract firms that are now looking for more than just a licence. We may see free zones offering 'substance packages' that include office space, recruitment support, and compliance services.
For firms, the key is to act now rather than wait for an audit. The cost of non-compliance is likely to be higher than the cost of restructuring. We recommend a thorough review of existing structures, with a focus on substance and transfer pricing.
Conclusion
The free zone pass-through is not dead, but it is evolving. Mid-market firms that adapt will continue to benefit from the UAE's tax advantages. Those that do not will face increasing scrutiny and potential penalties. The message is clear: substance is now the price of access.
