UAE Free Zone Substance Requirements: What the FTA is Checking and How to Pass

TL;DR

To qualify for the 0% corporate tax rate, a UAE free zone company must demonstrate economic substance in support of its core income-generating activities (CIGA) through four requirements:

• Qualified employees
• Physical assets
• Adequate operating expenditure
• Management and control in the UAE

Failing one requirement for a single tax period can trigger loss of QFZP status for five consecutive years. This guide also sets out the 12 documents an FTA examiner is likely to request on day one of a substance review.

If you operate a business in a UAE Free Zone and rely on the 0% corporate tax regime, having the right license and office is only part of the picture. The FTA also wants to ensure your business has a genuine presence in the UAE.

Understanding the Free Zone substance requirements UAE businesses must meet is therefore about more than having the right documents in place. Your employees, physical assets, operating expenditure, and management decisions all need to support the activities generating your qualifying income. And when the FTA reviews your position, the evidence behind those elements is significant.

In practice, the question is simple: if an FTA examiner asked you to prove how your business operates in the UAE, would your records tell a consistent story?

What the FTA Checks for Adequate Substance

Article 18 of the UAE Corporate Tax Law sets out the conditions a Free Zone entity must meet to qualify as a QFZP, including the requirement to maintain adequate substance in the UAE. The FTA’s Free Zone Persons Guide (CTGFZP1) provides further guidance on how these substance requirements are assessed in practice.

In practice, the substance assessment looks at the resources supporting the business’s CIGA, as well as where and how those activities are actually performed and managed.

1. Qualified Employees

The entity needs enough qualified personnel in the Free Zone to perform its CIGA effectively, with the technical skills, experience, and authority those activities require. For example, a services firm with one administrative employee in the UAE while offshore contractors perform the actual work may struggle to demonstrate adequate substance.

2. Adequate Physical Assets

The entity must have access to physical assets in the Free Zone that are appropriate to its activities. A logistics company may need warehouse or fleet access, while a software business may need appropriate development infrastructure and workstations. 

3. Adequate Operating Expenditure

The business must incur adequate operating expenditure in the Free Zone to support its CIGA. Operating expenses must reflect genuine economic activity (e.g., local salaries, physical rent, local utility bills, software licenses, local maintenance). Passive recharges or circular management fees routed from related parties are routinely challenged.

4. Strategic and Operational Management

The entity must demonstrate its Core Income-Generating Activities are directed, controlled, and managed from within the Free Zone. The supporting evidence can include board minutes, resolutions, and other records proving the key decisions were made in the UAE by people with the relevant authority and expertise.

Outsourcing Core Income-Generating Activities (CIGA)

Outsourcing can still be compatible with adequate substance, provided the QFZP retains sufficient in-house expertise and oversight to direct and evaluate the outsourced CIGA, and the service provider meets the applicable location requirements. Simply receiving deliverables or approving invoices, however, is unlikely to demonstrate the level of oversight the FTA expects.

For shared employees, contemporaneous timesheets and cost allocations should show the work performed for the QFZP.

What Ministerial Decision No. 229 Changes for Substance

Ministerial Decision No. 229 of 2025 replaced Ministerial Decision No. 265 of 2023 from June 1, 2023. While it does not replace the four substance requirements in Article 18, it changes the qualifying-activity framework those substance requirements support.

The activities a QFZP claims as qualifying determine what the FTA expects the entity to perform, control, and support in the UAE. Two changes under MD 229 have the most direct substance implications.

For commodity traders

Qualifying treatment now depends on a revenue threshold. If revenue from distribution, warehousing, logistics, or inventory management constitutes 51% or more of the QFZP’s total revenue for the relevant tax period, the entity cannot treat trading of qualifying commodities as a Qualifying Activity under MD 229.

For distribution businesses

Goods must enter the UAE through the Designated Zone and be supplied to customers who resell, process, or alter them, or to certain Public Benefit Entities. Distribution to other end consumers does not fall within this qualifying activity.

Companies that have already filed corporate tax returns under the previous framework should revisit their positions for any periods affected by MD 229, rather than assuming an earlier analysis remains valid.

The Five-Year Cost of a Single Substance Failure 

Article 18 makes the consequences of failing the substance test explicit. If the FTA determines a QFZP lacked adequate substance for a given tax period, the entity does not simply pay 9% corporate tax on the year’s net profit and correct course. It loses QFZP status for that period and the following four tax periods; a single year’s failure results in five consecutive years of standard corporate tax treatment. 

There is also a filing consequence. Companies that self-assessed as QFZPs and filed returns on this basis may need to restate if a later review establishes a substance failure for any open period. The FTA assesses for all open tax periods, regardless of when the original return was submitted.

For a business earning AED 10 million in annual qualifying income, this is an exposure of AED 4.5 million in additional tax across those five years, on income the business assumed was protected.

How Free Zone Substance Requirements in the UAE Differ by Business Type

Free Zone substance requirements in the UAE do not apply uniformly across every business. The FTA assesses substance relative to the specific qualifying activity being claimed. 

Trading Companies 

The FTA expects procurement documentation, supplier contracts, purchase orders, shipping records, and inventory management evidence. The FTA will want to see that the free zone entity itself has a meaningful role in directing the transaction chain, supported by staff with the authority to make the relevant purchasing and sales decisions.

Services Firms

The substance case for a professional services entity rests on demonstrating the work is being delivered from within the free zone. This means service contracts specifying scope and deliverables, timesheets or project records confirming staff involvement, and evidence that the professionals delivering the service are employed by or formally engaged through the entity. Where a company holds a services license but relies on a mainland or offshore affiliate to deliver the work, the FTA will expect the arrangement, responsibilities, and involvement of each entity to be clearly documented.

IP Holding Structures 

IP holding structures typically require particularly strong evidence because the value of the business may sit in an intangible asset rather than day-to-day operating activity. Owning an IP asset in the free zone is not the same as having adequate substance over it. The FTA expects evidence that your entity is actively directing and controlling the development, enhancement, maintenance, protection, and exploitation of the IP across the relevant periods. This requires development agreements, licensing decision logs, and staff or contractors with documented IP expertise engaged through the entity. A passively held IP asset with no record of active management will be challenged even if the four nominal tests appear satisfied.

What Adequate Substance Looks Like in Practice

A flexi-desk typically provides a registered business address and access to shared workspace rather than a dedicated office. It can be appropriate for some businesses, but the wider substance evidence needs to demonstrate that the entity genuinely conducts its relevant activities from the UAE.

The risk arises when the wider documentation does not show how the entity’s people, assets, and decision-making are connected to the operating location.

• Adequate: A dedicated office under a 12-month lease with access records, two full-time employees with UAE employment contracts and payroll registration, a client engagement log confirming meetings and deliverables managed from the UAE, and quarterly board minutes from sessions held in the free zone.
• Inadequate: A shared flexi-desk, one part-time employee on a nominal salary, a single client contract, and board resolutions dated from outside the UAE.

What matters is not simply how large the business is, but whether its UAE presence is proportionate to its activities. A smaller operation may have adequate substance, while a larger one may need to do more to demonstrate it.

Ultimately, the documentation should provide the FTA with a clear picture of the business activity taking place in the free zone and how it is connected to the qualifying income being claimed.

The 12 Documents to Prepare for an FTA Substance Review

When a substance review opens, the first document request sets the tone for the entire process. Keeping these twelve items organized and up to date can make an FTA review more straightforward, while also demonstrating your compliance framework is maintained as part of the business’s normal operations.

1. Trade license and free zone registration certificate covering the periods under review, current and in force.
2. Physical premises documentation: signed lease, access logs, office floor plan, and photographs confirming physical occupation of the space.
3. Employee register and contracts: employment agreements, Emirates ID copies, payroll records, and UAE social insurance registration evidence where applicable.
4. Organization chart showing reporting lines and the decision-making authority of locally based staff over the qualifying activity.
5. Board minutes and resolution register for the tax periods under review, confirming key decisions were taken in the UAE by qualified personnel.
6. Audited financial statements prepared in accordance with Ministerial Decision No. 84 of 2025, as referenced in MD 229.
7. UAE bank statements for the entity’s operating account, covering the relevant periods and reflecting active business transactions.
8. Operating expenditure schedule: a cost summary for the relevant periods, itemized by category and linked to the qualifying activity.
9. Revenue analysis by activity: a breakdown distinguishing qualifying income from excluded income, with supporting workings for any de minimis calculation applied.
10. Customer and supplier contracts for the qualifying activity, confirming the free zone entity is the contracting party, not a related entity acting in its place.
11. Intercompany agreements and transfer pricing documentation for transactions between the QFZP and related parties, demonstrating arm’s-length terms and a compliant pricing methodology.
12. IP documentation where applicable: ownership certificates, development and licensing agreements, and a log of exploitation decisions taken by the entity during the review period.

Not every gap in the checklist means the business needs to be restructured. Start by identifying where the evidence is weakest; this may mean formalizing employee roles, improving records of UAE-based decision-making, documenting outsourced activities, or strengthening the link between operating expenditure and qualifying activities.
