Cost Allocation Between Free Zone and Mainland Entities (2026)

Cost allocation gets companies audited. When a UAE business operates both a free zone entity (potentially taxed at 0%) and a mainland entity (taxed at 9%), every intercompany cost allocation is a potential transfer pricing issue. The Federal Tax Authority (FTA) scrutinises these allocations because the incentive to shift costs to the mainland entity — reducing its taxable profit while keeping income in the 0% free zone — is obvious and significant.

Getting cost allocation right is not optional. Incorrect allocations can result in tax reassessments, penalties of up to 300% of the underpaid tax, and loss of the free zone 0% tax rate entirely. The FTA expects documented, arm's length allocation methodologies supported by contemporaneous transfer pricing documentation.

This guide explains how to allocate costs between free zone and mainland entities correctly — the acceptable methods, documentation requirements, common mistakes, and what the FTA looks for during audits. For professional tax advice, visit the FindCPA corporate tax directory.

What Is Cost Allocation Between Free Zone and Mainland Entities?

Cost allocation between free zone and mainland entities is the process of distributing shared expenses — rent, salaries, technology, management fees, insurance, and administrative costs — between related entities in a way that reflects each entity's actual consumption of those resources. Under UAE corporate tax law, these allocations must follow the arm's length principle, meaning the prices and allocation methods must be the same as those that would apply between unrelated parties in comparable circumstances.

The challenge arises because most dual-structure UAE businesses share resources.

Common shared costs requiring allocation:

Why this matters for tax. A mainland entity pays 9% corporate tax on its taxable income. A qualifying free zone entity pays 0% on qualifying income. If shared costs are disproportionately allocated to the mainland entity, the mainland entity's taxable income decreases, and the group pays less total tax. The FTA views this as profit shifting and will reassess.

The arm's length standard. Article 34 of Federal Decree-Law No. 47 of 2022 requires all transactions between related parties and connected persons to be conducted at arm's length. This includes cost allocations. The FTA can adjust the taxable income of either entity if it determines that the allocation does not reflect what independent parties would agree to.

What Are the Acceptable Cost Allocation Methods?

The FTA accepts several cost allocation methods, provided they produce arm's length results: direct allocation (costs traced directly to the entity that incurred them), allocation based on usage metrics (headcount, square footage, revenue, time spent), and allocation based on OECD-recognised transfer pricing methods (cost plus, comparable unmanaged price, transactional net margin). The chosen method must be documented, consistently applied, and supportable with evidence. No single method is universally correct — the best method depends on the nature of each cost.

Allocation methods by cost type:

Three-tier allocation approach:

Tier 1 — Direct allocation. Where a cost clearly belongs to one entity, allocate it directly. Entity-specific audit fees, entity-specific legal matters, entity-specific rent — these should not be shared.

Tier 2 — Usage-based allocation. Where a cost is shared but usage can be measured, allocate based on measurable consumption. IT licences by user count, office space by square footage, payroll processing by number of employees.

Tier 3 — Proxy-based allocation. Where usage cannot be directly measured, use a reasonable proxy. Management time by revenue proportion, marketing by revenue or customer count, general overheads by a composite allocation key.

How Do You Document Cost Allocations for the FTA?

Cost allocation documentation must include an intercompany service agreement describing the services provided and costs allocated, a transfer pricing policy document explaining the allocation methodology and rationale, contemporaneous records showing the actual allocation calculations, supporting evidence for allocation keys (time sheets, headcount data, floor plans, transaction logs), and a benchmarking analysis demonstrating that the total cost plus markup is within arm's length range. This documentation must be prepared before or at the time of filing — not created retrospectively during an audit.

Documentation requirements checklist:

Intercompany service agreement essentials. The agreement between your free zone and mainland entities should specify:

• Nature of services provided
• Allocation methodology for each cost category
• Markup percentage (if applicable — typically 5-10% for low value-adding services)
• Payment terms
• Term and renewal provisions
• Dispute resolution mechanism

The markup question. When one entity provides services to another, the cost allocation usually includes a markup to reflect the service provider's profit. For low value-adding services (routine administration, basic IT support), a markup of 5% is common. For higher value-adding services (management, strategic support), markups of 7-15% are more appropriate. The benchmark must be documented.

Contemporaneous documentation. The FTA expects documentation to exist at the time of filing, not to be created after an audit notice is received. This means your allocation calculations, supporting data, and service agreements must be maintained in real time. Monthly allocation workpapers filed systematically are far more credible than a retrospective annual reconstruction.

What Are the Common Mistakes in Cost Allocation?

The five most common cost allocation mistakes are: allocating costs without a documented methodology, using a single allocation key (like revenue) for all costs regardless of their nature, failing to include a markup on intercompany services, not updating allocations when business circumstances change (new employees, changed office space), and treating the allocation as an annual exercise rather than an ongoing process. Each of these mistakes increases audit risk and can result in the FTA rejecting the entire allocation and substituting its own.

Mistake-by-mistake analysis:

Mistake 1: No documented methodology. Some companies allocate costs informally — the finance manager makes a "reasonable" split at year-end. Without documentation, the FTA has no basis to accept the allocation. They will substitute their own calculation, which will almost certainly be less favourable.

Mistake 2: Single allocation key for all costs. Allocating everything based on revenue is simple but wrong. Revenue is a reasonable key for some costs (marketing, management) but inappropriate for others (office rent should follow square footage, IT should follow user count). Using a single key suggests the allocation is arbitrary rather than analytical.

Mistake 3: No markup on intercompany services. If your mainland entity provides accounting services to your free zone entity, allocating costs at zero markup is not arm's length. An independent accounting firm would charge cost plus a profit margin. Your intercompany allocation should include a documented markup.

Mistake 4: Static allocations. If you set allocation percentages in January and use them all year despite changing circumstances (new hires in one entity, office expansion, new service lines), the allocation becomes inaccurate. Review and update allocation keys quarterly.

Mistake 5: Annual retrospective allocation. Allocating costs once per year during financial statement preparation is a red flag. The FTA expects ongoing allocations that are reflected in monthly or quarterly management accounts.

What Does the FTA Look for in a Cost Allocation Audit?

During an audit, the FTA examines whether intercompany cost allocations are supported by written agreements, whether the allocation methodology is documented and consistently applied, whether allocation keys are supported by verifiable data, whether markups are within arm's length range, and whether the net effect of allocations shifts profit from the higher-taxed entity to the lower-taxed entity. They compare total costs allocated versus the receiving entity's revenue to identify ratios that seem disproportionate. Any allocation that reduces mainland taxable income without corresponding economic substance will be challenged.

FTA audit focus areas:

The economic substance test. The FTA does not just check the mathematics of your allocation. They assess whether the allocated costs reflect actual services provided and consumed. If your free zone entity allocates management fees to the mainland entity, the FTA will ask: who provided the management services? What did they do? Where were they physically located? Is there evidence of the service being delivered?

Profit split analysis. The FTA compares entity-level profitability after cost allocations. If your free zone entity shows a 40% profit margin while your mainland entity shows 2%, the disparity will trigger scrutiny. The FTA will assess whether this profit split reflects economic reality or artificial cost shifting.

How Do You Set Up a Compliant Cost Allocation Framework?

Setting up a compliant cost allocation framework involves six steps: map all shared costs between entities, select an appropriate allocation method for each cost category, draft intercompany service agreements, implement the allocation in your accounting system with automated monthly calculations, benchmark markups against comparable transactions, and prepare transfer pricing documentation. The framework should be established before the first tax period and reviewed annually.

Implementation steps:

Step 1 — Cost mapping. List every cost that is shared between entities. Categorise each as direct (clearly belongs to one entity), allocable (shared but measurable), or overhead (shared without clear usage tracking). This mapping forms the foundation of your allocation framework.

Step 2 — Method selection. For each shared cost, select the most appropriate allocation method. Document why you chose that method and why alternatives were rejected. The documentation should demonstrate that you considered multiple methods and selected the one that best reflects economic reality.

Step 3 — Service agreements. Draft intercompany service agreements for each category of allocated costs. Have the agreements signed by authorised representatives of both entities. Ensure the terms are commercially reasonable — an independent party would accept them.

Step 4 — System implementation. Configure your accounting system to calculate and post intercompany allocations monthly. The allocation should appear in both entities' books — an expense reduction in the providing entity and a cost in the receiving entity. Automate as much as possible to ensure consistency.

Step 5 — Benchmarking. Conduct a benchmarking analysis to support your markup percentages. This can range from a simple comparable analysis to a full-scale transfer pricing study depending on the amounts involved.

Step 6 — Documentation. Prepare the transfer pricing policy document and maintain monthly workpapers. File everything systematically — if the FTA requests documentation, you should be able to produce it within days, not weeks.

Annual review cycle. At year-end, review the entire framework:

• Have business circumstances changed?
• Are allocation keys still accurate?
• Do entity-level profit margins look reasonable?
• Is the documentation complete and current?
• Are intercompany service agreements still reflective of actual services?

Frequently Asked Questions

Is a markup always required on intercompany cost allocations? For services (management, IT support, HR, accounting), a markup is generally expected to reflect the arm's length principle — an independent service provider would charge cost plus a profit margin. For pure cost pass-throughs (insurance premiums paid on behalf of the other entity, government fees), allocation at cost without markup is acceptable because no service is being provided.

What if our free zone entity only has qualifying income? Even if your free zone entity qualifies for the 0% rate, cost allocations must still be at arm's length. The FTA can disqualify income as non-qualifying if it determines that the free zone entity's profit is artificially inflated through non-arm's length cost allocations. Maintaining compliant allocations protects your qualifying status.

How detailed must our transfer pricing documentation be? For small intercompany transactions (below AED 500,000 annually), simplified documentation may be acceptable. For larger amounts, the FTA expects comprehensive documentation including a functional analysis, method selection rationale, benchmarking, and detailed calculations. Companies with total revenue exceeding AED 200 million must file a transfer pricing disclosure form.

Can we change our allocation methodology from year to year? You can change methodology if there is a valid business reason (changed operations, new entity, different service model). However, unexplained changes that conveniently reduce tax will be challenged. Document the reason for any methodology change and demonstrate that the new method produces a more accurate result.
