How to Calculate Zakat for Your Business in Saudi Arabia (2026 Guide)

Zakat is one of the Five Pillars of Islam and a legal obligation administered by ZATCA for businesses owned by Saudi and GCC nationals. Yet despite its centrality to Saudi business life, the Zakat base calculation remains widely misunderstood — and incorrectly calculated Zakat is one of the most common triggers for ZATCA audit and assessment.

The Zakat Base Formula

The starting point for every business Zakat calculation is the Zakat base — broadly equivalent to the net working capital of the company adjusted for a series of ZATCA-specific additions and deductions. The formula is:

Zakat Base = Zakatable Assets − Eligible Deductions

The Zakat rate is then applied: 2.5% on a solar year basis, or approximately 2.577% on a lunar (Hijri) year basis. ZATCA generally accepts either basis applied consistently year-to-year.

What Goes Into the Zakat Base?

Zakatable Assets (Add)

• Trade inventory: All goods held for resale at cost — finished goods, work-in-progress (for manufacturers), and raw materials
• Cash and bank balances: All SAR and foreign currency cash, current accounts, and short-term deposits
• Trade receivables (net): Customer invoices outstanding, net of a specific provision for bad debts supported by documentation
• Advances to suppliers: Prepayments to suppliers for goods or services not yet received
• Short-term investments: Investments in listed securities and money market instruments held for less than 12 months
• Intercompany receivables: Amounts owed by related companies are generally included unless they represent long-term financing

Eligible Deductions (Subtract)

• Property, plant and equipment (net book value): Fixed assets used in the business — buildings, machinery, vehicles, computers — are excluded from the Zakat base
• Long-term investments: Investments in subsidiaries, associates, and other equity holdings held as strategic investments
• Losses carried forward: Tax losses from prior years that are eligible for carry-forward under ZATCA rules
• Long-term debt: Bank loans and bonds with a maturity of more than 12 months from the balance sheet date
• Statutory reserves: Legal reserves required under Saudi Company Law are excluded from the Zakat base

Applying the Saudi Ownership Percentage

For companies with mixed Saudi and foreign ownership, the Zakat base is multiplied by the Saudi/GCC ownership percentage. The foreign-owned portion is subject to Corporate Income Tax (CIT) at 20% on profits instead of Zakat. This allocation must be carefully documented as ZATCA auditors frequently scrutinise the ownership percentage applied.

Common Zakat Calculation Mistakes

1. Using net profit instead of working capital: Zakat is not a profit tax — it is calculated on the Zakat base (a modified balance sheet measure), not on accounting profit. Companies that calculate Zakat as 2.577% of net profit will almost always pay too little or too much.
2. Incorrect fixed asset treatment: Some businesses incorrectly add back accumulated depreciation when calculating fixed assets for Zakat purposes. ZATCA generally allows the net book value (cost less accumulated depreciation) as the deductible amount.
3. Ignoring intercompany balances: Receivables from related companies are often omitted from the Zakat base, understating the liability. ZATCA auditors specifically check intercompany account treatment.
4. Wrong rate application: The 2.5% solar rate and 2.577% lunar rate are both acceptable — but you must apply the same rate consistently every year. Switching between rates without documentation attracts ZATCA queries.
5. Late filing without extension: The Zakat return is due 120 days after year-end. If you are not going to make the deadline, apply for a 60-day extension before the original due date — the extension must be requested proactively, not after the deadline passes.

ZATCA's Voluntary Disclosure Programme

If you have underpaid Zakat in prior years, ZATCA's Voluntary Disclosure Programme allows you to correct prior filings with reduced penalties — in some cases a complete penalty waiver for the first VDP submission. Acting before ZATCA initiates its own audit is strongly advisable. Once an audit is opened, VDP protections no longer apply to the period under review.

When to Seek Professional Help

A straightforward company with simple ownership structure and clean books can often manage Zakat filing internally. But professional assistance is strongly recommended when: (1) the company has mixed Saudi/foreign ownership; (2) there are intercompany transactions with related parties; (3) ZATCA has issued an amended assessment you disagree with; or (4) the company has had a significant change in capital structure, major asset acquisitions, or M&A activity during the year.
