The Arm's Length Principle in Saudi Arabia: What It Actually Means for Your Intercompany Transactions

The Arm’s Length Principle: The Foundation of All Transfer Pricing

Every transfer pricing rule in Saudi Arabia — every documentation requirement, every method, every ZATCA adjustment — flows from a single principle: transactions between related parties must be priced as if those parties were independent. That is the arm’s length principle, and understanding it precisely is the starting point for everything else.

The principle sounds straightforward. In practice, applying it is one of the most analytically demanding tasks in corporate tax. There is no published price list for management fees, no Reuters ticker for intercompany royalty rates. Determining what independent parties would have agreed requires a structured analysis of functions, risks, assets, comparable transactions, and economic circumstances. Get that analysis right, and your transfer pricing position is defensible. Skip any part of it, and ZATCA has the opening it needs.

This article explains exactly how the arm’s length principle operates under Saudi Arabia’s TP framework — what it means legally, how it is applied analytically, and where the most common compliance failures occur in practice.

The Legal Definition Under Saudi TP Rules

The arm’s length principle is defined in the Saudi TP Bylaws (Board Resolution No. [6-1-19], 2019) by reference to the OECD standard: where conditions are made or imposed between related persons in their commercial or financial relations which differ from those which would be made between independent persons, any profits which would have accrued to one of those persons but for those conditions may be included in the profits of that person and taxed accordingly.

In plain terms: if a Saudi entity and its related party price a transaction differently from how two independent parties would have priced the same transaction under comparable circumstances, ZATCA can adjust the Saudi entity’s income to reflect the arm’s length outcome — and tax the difference. This adjustment power is conferred by Article 4 of the TP Bylaws.

The arm’s length principle applies without any materiality threshold. There is no minimum transaction value below which the principle does not apply. Documentation thresholds (SAR 6 million for Master File and Local File) determine what must be formally prepared and produced on request — but the underlying pricing obligation applies to every controlled transaction, regardless of size.

The Comparability Analysis — How Arm’s Length Is Actually Determined

Applying the arm’s length principle requires a comparability analysis. This is a structured process — and it is not optional. ZATCA’s Guidelines set out the required steps, and a Local File that skips any of them is likely to be challenged.

Step 1: Identify the Controlled Transaction

Begin with a broad-based analysis of the industry, the MNE group’s business, and the general operations of the related parties involved. This establishes the commercial context within which the specific transaction sits. You cannot properly analyse a management fee without first understanding what functions the group performs, how it is structured, and where value is actually created.

Then move to the controlled transaction itself. What exactly is being transferred or provided? What are the contractual terms? What is the commercial rationale? The controlled transaction must be accurately delineated before any comparability assessment can begin.

Step 2: Functional Analysis — The Most Important Step

The functional analysis examines three things: what each party does (functions performed), what each party owns or uses (assets employed — tangible and intangible), and what each party stands to gain or lose (risks assumed). The allocation of arm’s length profit between the parties should track this allocation of functions, assets, and risks. A party that performs only routine functions, owns no significant intangibles, and bears limited risk should earn a routine, market-benchmarkable return — no more.

This is where most TP analyses are inadequate in practice. A functional analysis that simply says “the Saudi entity performs manufacturing and the parent provides oversight” is not analysis — it is a description. ZATCA expects a detailed, transaction-specific characterisation that explains precisely what each party does, what risks each party contractually bears versus those it actually manages and controls, and what assets each party contributes to the transaction’s value creation.

Step 3: The Five Comparability Factors

With the transaction accurately delineated, the comparability analysis assesses whether the conditions of that transaction align with those of comparable uncontrolled transactions. ZATCA’s Guidelines, following the OECD framework, identify five factors:

Step 4: Selecting Comparables and Establishing the Arm’s Length Range

Comparables fall into two categories: internal comparables (transactions the taxpayer itself conducts with independent parties on similar terms) and external comparables (transactions between independent third parties in comparable circumstances, drawn from commercial databases or public sources). Internal comparables are always preferred — they eliminate many of the adjustment issues that arise with external data.

Where multiple comparables are identified, they form an arm’s length range. ZATCA expects the interquartile range to be used, with the median as the target point for the transfer pricing policy unless the taxpayer provides substantiated reasons to use a different point. Any result within the interquartile range is generally acceptable.

Worked Example — Applying Arm’s Length to a Service Fee

Let’s apply the analysis step by step to a common Saudi scenario.

Where the Arm’s Length Analysis Most Often Fails

• No genuine functional analysis — just a description. ZATCA expects a proper allocation of functions, assets, and risks between the parties. A document that describes what each party does without analysing what economic risks each party actually manages and controls is not a functional analysis — it is background. The burden of proof is not met by description alone.
• Charging for services that fail the benefit test. A management fee that primarily covers group-level shareholder oversight, global consolidated reporting, or parent-level governance does not provide a direct, identifiable benefit to the Saudi entity. ZATCA can disallow or reduce fees that cannot be traced to services that benefit the recipient. Every line item in a service charge must pass the benefit test.
• Using stale or geographically inappropriate comparables. Benchmarks drawn from European or North American databases must be assessed for their applicability to the Saudi market. Economic circumstances differ. If the comparable set is not adjusted for material geographic differences, the resulting arm’s length range may not be reliable for Saudi purposes.
• Pricing at the lower bound of the range without explanation. Consistently placing transfer prices at the lower end of the arm’s length range — which typically produces lower Saudi taxable income — without substantiation is a pattern ZATCA will scrutinise. The expectation is the median absent a specific reason to deviate.
• Ignoring changes in functions, assets, or risks over time. The arm’s length analysis must reflect the actual economic reality at the time of the transaction. If the Saudi entity’s functional profile changes — it takes on more risk, develops proprietary assets, or expands its functions — the TP analysis must be updated. Using a benchmark study from three years ago for a materially different business is not defensible.
