UAE transfer pricing documentation: the master file, local file and disclosure form for GCC groups

Why transfer pricing now applies to everyone, not just big MNEs

There's a common misconception that transfer pricing is only a concern for large multinationals with revenues in the billions. That was never the intent of the UAE's framework, and the FTA has been explicit about this. Under Ministerial Decision No. 97 of 2023 and subsequent guidance, every taxable person subject to UAE corporate tax must price related-party transactions at arm's length. This applies whether you're a two-entity holding structure in DIFC or a sprawling family group with operations across four Emirates.

The arm's length principle in the UAE mirrors OECD guidelines, meaning the FTA expects you to benchmark intercompany charges against what independent parties would agree to under comparable circumstances. Free zone entities aren't exempt either. If a free zone company claims the 0% rate but transacts with a mainland related party, those transactions must comply with transfer pricing rules to prevent profit shifting. The days of treating intercompany invoices as an internal accounting exercise are over.

Who is caught: related parties and connected persons

The UAE's definitions of related parties and connected persons cast a deliberately wide net. A person is "related" to another if one controls or owns 50% or more of the other, or if a third party holds 50% or more in both. But the rules go further: directors, partners, and their relatives up to the fourth degree of kinship can also trigger related-party status.

Connected persons are a separate but overlapping category. This includes individuals who are partners in the same unincorporated partnership, or entities where one participates in the management, control, or capital of the other. For GCC family groups, this is where things get complicated fast. A father and son each owning separate companies in different Emirates are connected persons. A management company providing services to a sister entity at below-market rates is caught. Even informal arrangements, like a shared finance team that doesn't charge for its time, create transfer pricing exposure if not properly documented.

The three documents: disclosure form, local file and master file

The UAE transfer pricing documentation framework has three tiers, each serving a different purpose.

The transfer pricing disclosure form is mandatory for every taxable person that has related-party or connected-person transactions. You file it alongside your corporate tax return. It captures the nature of each transaction, the amounts involved, and the transfer pricing method used. Think of it as the FTA's first screening tool: it tells them where to look if something seems off.

The local file is a detailed, entity-level document. It describes the specific intercompany transactions of a single UAE entity, the functional analysis behind them, the comparability analysis, and the pricing method selected. It must demonstrate, with evidence, that each transaction satisfies the arm's length standard. This is the document the FTA will scrutinise most closely during an audit.

The master file provides a top-down view of the entire multinational or multi-entity group: its organisational structure, business operations, intangible assets, intercompany financial activities, and global transfer pricing policies. For GCC groups, the master file is where you show how the pieces fit together.

The thresholds: which entities need the master and local file, plus CbCR

Not every entity needs all three documents. The disclosure form is universal, but the master file and local file only become mandatory once your group hits specific thresholds.

• A local file is required if the taxable person's revenue in the tax period is at least AED 200 million, or if it belongs to a multinational group with consolidated revenue of at least AED 3.15 billion. Within the local file itself, a materiality threshold then governs which related-party transactions must be documented.
• A master file is required under the same two triggers: AED 200 million of revenue, or membership of a multinational group above AED 3.15 billion.
• Country-by-Country Reporting (CbCR) kicks in when the consolidated group revenue exceeds AED 3.15 billion (approximately EUR 750 million), aligning with the OECD's BEPS Action 13 framework.

Here's what catches people out: even if you fall below these thresholds, the FTA can still request transfer pricing documentation at any time. The thresholds determine what you must prepare proactively. Below them, you're not off the hook: you simply have a 30-day window to produce documentation if the FTA asks for it. That's not much time to build a local file from scratch, which is why many advisers recommend preparing documentation regardless of whether you technically have to.

Deadlines and the 30-day FTA request

Your transfer pricing disclosure form is due with your corporate tax return, which must be filed within nine months of the end of the relevant tax period. For a December year-end, that means 30 September of the following year.

The master file and local file don't get filed with the return. Instead, they must be maintained and ready to submit within 30 days of an FTA request. This is a hard deadline: there's no extension mechanism baked into the rules. If the FTA sends a request on 1 March, you have until 31 March. Miss it, and you're looking at penalties under the UAE's administrative penalties framework, which can include fixed fines and percentage-based penalties on underpaid tax.

The practical implication is straightforward. You should treat your documentation as something you prepare contemporaneously, not retrospectively. Building a local file months or years after a transaction happened is both harder and less credible. The FTA's risk-based audit selection process increasingly cross-references VAT filings, corporate tax returns, and economic substance declarations. Inconsistencies between these data points are a known trigger.

Scoping a multi-entity GCC group, and the mistakes that catch them

GCC groups face a particular set of challenges. Saudi Arabia has its own transfer pricing rules under the zakat and income tax framework, and recent compliance updates in 2026 have tightened documentation expectations there as well. Oman, Bahrain, Qatar, and Kuwait each have their own tax regimes with varying degrees of transfer pricing enforcement. A group with entities in three or four GCC countries needs to coordinate documentation across jurisdictions, not just satisfy the UAE's requirements in isolation.

The most common mistakes Cosmos sees when working with multi-entity GCC groups fall into a few patterns:

• Using a single generic intercompany agreement across all entities, regardless of the actual functions performed, assets used, or risks assumed by each one.
• Failing to charge for management services, shared services, or the use of intellectual property between group companies, creating a deemed benefit that the FTA can recharacterise.
• Relying on prior-year benchmarking studies without updating them, even when the business model or transaction volumes have changed materially.
• Treating free zone entities as entirely separate from the group's transfer pricing framework, despite the clear rules requiring arm's length pricing for mainland-free zone transactions.

Each of these creates exposure. The FTA isn't looking for perfection, but it is looking for genuine economic substance behind intercompany arrangements. A management fee charged at 5% of revenue needs to be justified by a functional analysis showing what services are actually provided, by whom, and why 5% reflects the arm's length price.

Getting documentation audit-ready

The difference between documentation that exists and documentation that survives an audit is substance. A local file that recites the rules but doesn't contain a proper comparability analysis, or that uses a benchmarking database search without explaining the rejection criteria for comparables, will not hold up.

Start with the functional analysis. Map each entity's functions, assets, and risks for every material intercompany transaction. Then select the most appropriate transfer pricing method: whether that's CUP, TNMM, cost-plus, or another recognised method. Document why you chose it and why alternatives were rejected. Your benchmarking study should use current data, ideally from the same or immediately prior financial year, and the search strategy should be reproducible.

Intercompany agreements deserve special attention. Generic templates downloaded from the internet are a red flag. Each agreement should reflect the actual commercial terms, payment schedules, and service specifications of the arrangement. If your agreement says "advisory services" but there's no evidence of any advice being given, the FTA will notice.

Cosmos regularly helps groups structure their documentation programme so that the master file, local file, and disclosure form work as a coherent package. The master file feeds into the local file, and the local file supports the numbers on the disclosure form. When all three tell a consistent story, you're in a strong position. When they contradict each other, or when one is missing entirely, you're exposed.

If you haven't started preparing your UAE transfer pricing documentation for the current period, the time to act is now: not 29 days after the FTA sends its request. This is general information, not tax advice: confirm your obligations with a qualified adviser.
