Related-Party Transactions Between Free Zone Companies and the Mainland

Every transaction between a free zone company and a mainland related party has two tax sides. On the free zone side, the question is whether the income is qualifying income at 0% or non-qualifying income at 9%, and whether the price is arm's length. On the mainland side, the counterparty is taxed at the standard rate, and the same price determines its deduction or its revenue.

Because the two sides face different rates, the pricing incentive is obvious - and the FTA knows it. A mainland parent has an incentive to overpay its free zone subsidiary for services, shifting profit from 9% to 0%. A free zone subsidiary has an incentive to underpay its mainland parent, with the same effect. Article 34 exists precisely to neutralise these incentives: the price must be what independent parties would have agreed.

The mainland counterparty's deduction adds a second audit surface. Even if the free zone company is comfortable with its 0% position, the FTA can challenge the mainland company's deduction for a non-arm's length payment. Price the transaction once, defend it on both sides, and keep one consistent file.

The customer route to qualifying income requires a Free Zone Person counterparty, so it never helps with mainland customers. The activity route is the only path: income from a mainland related party is qualifying income only if it is genuinely derived from a qualifying activity that is not an excluded activity under Ministerial Decision No. 229 of 2025.

This is a facts-and-evidence test, not a labelling exercise. A free zone company providing headquarters services to its mainland parent can use the activity route - headquarters services to related parties are a qualifying activity - but it must evidence the actual headquarters functions, the related-party relationship, and the arm's length price. A free zone company selling ordinary goods to a mainland customer cannot use the activity route unless the sale genuinely falls within a qualifying activity such as distribution in or from a Designated Zone.

The common failure is assuming that any service a free zone company provides to a mainland affiliate is qualifying because the provider holds a free zone licence. The licence is irrelevant to the test. What matters is the statutory description of the activity actually performed.

Management and headquarter services from either direction are priced by first applying the benefit test: would an independent party have paid for this service, or performed it itself? Shareholder activities and duplicated services fail the test and cannot be charged at any price. Genuine services are typically priced with the cost plus method for routine support, with allocation keys that reflect real usage.

Goods flowing between the free zone and the mainland - a free zone manufacturer selling to a mainland distributor, or a mainland supplier selling components to a free zone assembler - are usually priced with the comparable uncontrolled price method where good comparables exist, or the transactional net margin method with a tested party that matches the functional profile. Watch the Designated Zone boundary for distribution: the qualifying-activity analysis and the pricing analysis must tell the same story about where the distribution happens.

Financing between the free zone and the mainland needs an arm's length interest rate supported by the borrower's creditworthiness, the loan terms and market benchmarks - not the group's internal treasury rate applied by default. Guarantees provided across the border need a separate guarantee fee analysis where the guarantee provides a real benefit.

The disclosure form captures these transactions like any other controlled transaction, but the FTA reads them with extra attention because of the rate differential. Expect the auditor to start with the qualifying-activity mapping for every mainland-customer revenue stream, then move to the pricing: the method, the comparables, and whether the tested party's functional profile matches the story.

Keep the mainland and free zone files consistent. The mainland company's local file and the free zone company's local file describe the same transaction from opposite sides; contradictions between them - different functional profiles, different methods, different prices - are the fastest route to adjustments on both sides.

Where the group has taken a position that mainland-customer income is qualifying through the activity route, document the position as a tax technical position with the statutory references, not just as a line in a spreadsheet. If the FTA disagrees, a reasoned, disclosed position supports penalty mitigation in a way that an unexplained classification never does.
