Both — proportionally. A 50/50 mixed-ownership JV is subject to Zakat on 50% of its Zakat base (the Saudi-owned portion) and CIT on 50% of its taxable income (the foreign-owned portion). The two calculations are entirely independent and both must be filed and paid within 120 days of the fiscal year-end.

There is no choice between the two regimes. The ownership structure determines the split automatically. Both obligations arise simultaneously from the same entity’s activity in the same fiscal year. The entity pays 2.5% Zakat on its Saudi-apportioned Zakat base and 20% CIT on its foreign-apportioned taxable income — neither instead of the other, but both in parallel.

This is the question that surprises non-Saudi investors most often. The assumption is that a company is either a Zakat payer or a CIT payer. For mixed-ownership entities, it is always both.

Year-end ownership applies. Under Article 13 of the Zakat Implementing Regulations, a Zakat Payer is held accountable at year-end — the ownership percentage at the close of the fiscal year is the percentage used for both the Zakat and CIT calculations, applied to the full year’s figures.

There is no time-apportionment within the year. If a company starts the year as 100% Saudi-owned and sells a 40% stake to a foreign investor in October, the year-end split of 60% Saudi / 40% foreign applies to the full year. The CIT obligation covers 40% of the entire year’s taxable income — not just the three months from October to December. Similarly, Zakat applies to 60% of the full year’s Zakat base.

One critical CIT exception: where foreign ownership changes by 50% or more, Article 11(4) of the Income Tax IR restricts the loss carry-forward on the CIT side. Losses accumulated before the ownership change cannot be carried forward into years after the change unless the company continues to practise the same activity. Finance teams modelling share transactions that move the foreign share above or through the 50% threshold must assess this loss restriction explicitly.

Zakat. The Zakat Implementing Regulations define “Saudi” to include nationals of GCC member states (Kuwait, UAE, Bahrain, Qatar, Oman) who are accorded treatment similar to Saudi nationals. A GCC national holding shares in a Saudi company is a Zakat payer on those shares — not a CIT payer.

This is a frequently misapplied rule. Non-Saudi finance professionals — and even some advisors — sometimes assume that “non-Saudi” automatically means “CIT.” For GCC nationals, that assumption is wrong. The GCC national is treated as Saudi for fiscal purposes in Saudi Arabia, meaning their shareholding creates a Zakat obligation, not a CIT obligation.

The practical consequence is important for JV structuring: a joint venture between a Saudi investor and a Kuwaiti investor is 100% subject to Zakat — not partially subject to CIT. Both shareholders’ portions are within the Zakat framework. The CIT regime is triggered only by non-GCC foreign ownership.

Not necessarily. Zakat is calculated on the Zakat base — an equity/wealth-derived measure — not on profit. If a company has positive accumulated equity (retained earnings from prior profitable years) even while making a current-year loss, the Zakat base may remain positive and Zakat will be owed on the Saudi-apportioned portion.

The loss reduces equity, which reduces the Zakat base, but does not eliminate it unless the entire equity is wiped out. A company with SAR 40 million in retained earnings that loses SAR 5 million in the current year has equity of approximately SAR 35 million (plus capital). The Zakat base — derived from this equity after adjustments — may still be substantial.

This asymmetry between Zakat and CIT is one of the most commercially significant differences between the two regimes. In a bad trading year: the CIT obligation on the foreign share is zero (a loss carry-forward arises), while the Zakat obligation on the Saudi share may still be material if equity remains positive. Finance teams must model both bases independently in every year — including loss years — and should never assume that a loss year means no Saudi direct tax obligations at all.

No. Zakat and CIT are separate obligations, administered through separate ZATCA return forms, using separate computation methodologies, and filed as distinct documents. There is no combined return option that discharges both obligations simultaneously.

Both returns are filed through ZATCA’s electronic systems and both are due within 120 days of the fiscal year-end (the same calendar deadline for calendar-year entities). Both may require CPA certification where revenues reach applicable thresholds. The same financial statements and the same CPA firm can be used for both — but the returns themselves are separate documents reflecting separate calculations.

In addition to the Zakat and CIT returns, a mixed-ownership entity that makes payments to non-residents also has an annual WHT information return obligation — a third separate ZATCA filing with the same 120-day deadline. Three separate filings, one deadline, all by the same entity.

No. There is no minimum ownership threshold in either the Zakat or CIT framework. Even a 1% Saudi shareholding creates a Zakat obligation on 1% of the Zakat base. Even a 1% foreign shareholding creates a CIT obligation on 1% of taxable income.

The proportional rule applies at any ownership level without exception. A company with 99% Saudi ownership and 1% foreign ownership must file both a Zakat return and a CIT return — the CIT obligation on 1% of taxable income at 20% may be small, but it exists and must be reported and paid.

This matters particularly for entities where foreign investors hold small strategic stakes — a 5% technology partner, a 10% financial investor, a 15% international joint venture partner. Each of these creates a CIT filing obligation for the entity, in addition to the Zakat obligation on the remaining Saudi-owned majority. The compliance burden exists regardless of the size of the foreign shareholding.

No. Under Article 1(c) of the Income Tax Implementing Regulations, the tax base for resident capital companies is calculated independently from the tax base of their shareholders, partners, or subsidiary companies — even where consolidated accounts have been prepared. The parent’s CIT base does not include its share of subsidiary profits recognised through the equity method.

This is the independent tax base rule — one of the most important structural features of Saudi tax for group structures. A Saudi holding company that owns 100% of a Saudi operating subsidiary does not include the subsidiary’s SAR 20 million profit in its own CIT taxable income. The subsidiary pays its own Zakat or CIT on those profits at the subsidiary level. The holding company’s CIT base is only its own revenues: dividends received (which may qualify for the participation exemption), management fees, interest income, and similar items generated at the holding company level.

The same logic applies in reverse: a subsidiary’s losses do not reduce a parent’s CIT base. There is no loss relief or loss surrender between Saudi entities — each entity’s tax position is computed entirely independently.

The compliance risks are serious and compounding. An error in applying the ownership split rule is not a standalone mistake — it causes every subsequent calculation, filing, and payment to be incorrect. The downstream consequences include: ZATCA assessments on underpaid Zakat or CIT, delay penalties (1% per 30 days) running from the original filing deadline, potential non-filing penalties, and — in cases of persistent non-compliance — fraud penalty exposure.

Beyond the direct financial penalties, there are commercial and practical consequences. Saudi shareholders and their companies require ZATCA compliance certificates for many government contracts, licences, and regulatory approvals. An unresolved Zakat assessment creates compliance certificate blockages that can prevent a company from winning new business, renewing licences, or completing commercial transactions. For joint ventures, a Zakat compliance failure by the entity can affect the Saudi partner’s own compliance standing, not just the entity’s.

The most common ownership split errors and their consequences:

• Filing CIT only — ignoring Zakat: ZATCA assesses unpaid Zakat with delay penalties for every year. The Saudi shareholder may lose access to compliance certificates. ZATCA’s assessment powers on Zakat are up to five years (standard) and ten years (late or incomplete filing).
• Filing Zakat only — ignoring CIT: ZATCA assesses CIT on the foreign-owned share with delay penalties. Where books are inadequate, ZATCA uses estimated profit margins (80% for management fees, 20% for services) — potentially vastly overstating the correct liability.
• Using consolidated accounts as the tax base: The standalone entity’s Zakat and CIT computations are incorrect at the starting point. Both returns require restatement.
• Not updating the split after an ownership change: Prior-year returns may be misstated. The 50%+ ownership change CIT loss restriction may not have been applied, resulting in carry-forwards that ZATCA will disallow.

Self-correction before a ZATCA audit is always preferable — voluntary disclosure avoids the enhanced scrutiny and potential fraud provisions that can accompany auditor-identified errors.
