The Saudi/foreign joint venture is where the ownership split rule generates the most practical compliance complexity — because both regimes apply simultaneously, with full force, to the same entity, from the same set of financial statements, under the same deadline, but via entirely separate calculations.

A purely Saudi-owned company deals only with Zakat. A purely foreign-owned entity deals only with CIT. The JV must manage both — and the challenge is not merely doing two calculations but understanding that they start from different places, apply different adjustments, and can produce divergent results depending on the year’s financial profile. The finance team, the external advisors, and the JV governance structure all need to accommodate this dual-regime reality from day one.

The proportional split applies the Saudi ownership percentage to the Zakat base and the foreign ownership percentage to the taxable income. These percentages are determined at year-end. There is no time-weighting within the year — it is a point-in-time snapshot at the close of the fiscal year.

Step 1: Determine Year-End Ownership

Identify the exact Saudi/GCC and non-Saudi ownership percentages as recorded in the company’s register at the end of the fiscal year. For entities where ownership has changed during the year, the year-end percentages apply for both Zakat and CIT calculation purposes.

Step 2: Prepare the Zakat Computation (Saudi Share)

Derive the Zakat base from the entity’s balance sheet per the Zakat IR methodology: start from equity, add certain external liabilities, deduct settled non-current assets, and apply the minimum Zakat base floor rules. Multiply the resulting Zakat base by the Saudi ownership percentage. Apply 2.5% to calculate Zakat due.

Step 3: Prepare the CIT Computation (Foreign Share)

Derive taxable income from the entity’s income statement: total revenues from taxable activities less all allowable deductions under the Income Tax IR. Multiply by the foreign ownership percentage. Apply 20% to calculate CIT due. Carry forward any loss on the foreign share (subject to the 25% annual utilisation cap in future years).

Step 4: File Both Returns and Pay Both Obligations

Both returns are filed by the entity (not by the individual partners) with ZATCA within 120 days of the fiscal year-end. Where revenues reach SAR 1 million or more, both returns require CPA certification. Both payments are made by the entity to ZATCA.

Article 1(c) of the Income Tax Implementing Regulations provides that the tax base for a resident capital company is calculated independently from the tax base of its shareholders, partners, or subsidiary companies — even if consolidated accounts have been prepared. The CIT base does not include the entity’s share of profits or losses from investments reported using the equity method. A subsidiary’s profits stay in the subsidiary; they do not flow through to the parent’s CIT base.

This “independent tax base” rule is essential for JV structures with multi-layered ownership. Consider a JV that owns a 40% stake in another Saudi company — the JV does not include its share of that subsidiary’s profits in its own CIT taxable income. If the subsidiary distributes a dividend, that dividend may qualify for the participation exemption (10% shareholding held for at least one year) and be exempt from CIT at the JV level.

For Zakat, the parallel principle appears in the Zakat IR’s treatment of investments: investments in other Saudi-registered entities subject to Zakat may be deducted from the investing entity’s Zakat base (under Article 43 of the Zakat IR), avoiding a duplication of Zakat on the same underlying wealth at multiple levels of the corporate structure.

The JV entity’s management — which in most Saudi JVs is dominated by one of the partners or an agreed management committee — bears the practical obligation to ensure both returns are filed and both taxes are paid. The foreign partner cannot file its own CIT return independently of the JV entity structure; the obligation sits with the entity.

This creates a governance question that JV agreements should address explicitly: who is responsible for preparing and filing the Zakat return? Who prepares the CIT computation? How are disputes between partners about the tax position handled? What happens if one partner disagrees with the tax computation? These are not theoretical questions — they arise regularly in Saudi JVs, particularly when the foreign partner has its own group tax team with views on the CIT position.

Best practice is to agree a clear tax governance protocol in the JV agreement itself: which party or external advisor prepares each computation, who reviews and approves, what the approval timeline is relative to the filing deadline, and how costs are allocated between the partners.

Where a JV has multiple non-Saudi shareholders from different countries, the CIT obligation applies to the aggregate foreign ownership percentage — not separately to each foreign partner’s individual share. The JV entity computes CIT on (total foreign ownership %) × taxable income and files a single CIT return.

The foreign partners’ own home-country tax positions — including any DTT treaty relief or foreign tax credit claims — are matters for each partner to manage in their own jurisdiction. The Saudi JV entity’s CIT is a cost of the entity, not a directly charged cost to specific individual foreign partners unless the JV agreement allocates the CIT burden explicitly.

Where foreign partners are from different treaty jurisdictions, the dividend WHT rate on distributions from the JV may differ between partners. The JV entity should maintain records of which foreign partner receives which portion of any dividend distribution to apply the correct treaty rate (or domestic rate) to each partner’s share.

If the JV makes a loss, does it still owe Zakat?

Potentially yes. Zakat is calculated on the Zakat base — an equity/wealth measure — not on profit. If the JV has positive accumulated equity (from prior profitable years) even while making a current-year loss, the Zakat base may still be positive and Zakat will be owed on the Saudi-apportioned portion. The loss reduces equity, which reduces the Zakat base, but does not necessarily eliminate it entirely. The CIT obligation, by contrast, is zero in a loss year — and the loss carry-forward is available for future profitable years.

Who physically pays the Zakat and CIT to ZATCA?

The JV entity pays both — not the individual partners. The entity files the Zakat return, pays the Zakat liability, files the CIT return, and pays the CIT liability, all directly with ZATCA. The partners’ indirect obligation is through their ownership and the governance arrangements in the JV agreement. In practice, the entity’s finance team or CFO manages the ZATCA relationship, and the cost is recorded as a tax expense in the entity’s books.

How should intragroup service fees between the JV and its foreign parent be treated?

Service fees from the JV to the foreign parent are potentially deductible for CIT (on the foreign-owned portion), subject to arm’s length transfer pricing. They also trigger WHT obligations on the JV as the Saudi payer. The Zakat computation is unaffected by the service fees in terms of WHT, but the fees reduce the entity’s equity (and therefore its Zakat base) over time if consistently paid. Three separate analyses are required: CIT deductibility, WHT rate, and the Zakat base impact — all from the same payment.
