Zakat, Corporate Tax and Withholding in Saudi Arabia: What Bookkeepers Must Separate

This is for the bureau that keeps books for Saudi client entities and has to produce three computations from one ledger. The rules are not hard to read. What is hard is that zakat, income tax and withholding draw on different parts of the accounting record, on different cycles, and a chart of accounts built for management reporting will not produce any of them without a rebuild in March.

Who pays zakat, who pays income tax, and who pays both

The split is by ownership, not by activity or size.

ZATCA states that the Income Tax Law applies to "resident capital companies with respect to the shares owned by non-Saudi partners, whether such partners are natural or legal persons, resident or non-resident", and to non-residents doing business through a permanent establishment or deriving income from Saudi sources. ZATCA's Regional Headquarters guideline puts the other half: zakat applies to resident companies "on the basis of the shares owned by Saudi or Arabian Gulf Cooperation Council citizens", and to anyone practising an activity under a licence issued in the Kingdom.

The two charges are complementary, not alternative. A company owned 60 per cent by a Saudi family and 40 per cent by a European group is not a zakat company or a tax company. It is both, in proportion, and the year-end pack carries two computations built on two different foundations.

Ownership profile	What it pays	What the ledger must separate
Wholly Saudi or GCC owned	Zakat	Equity by component (capital, statutory and voluntary reserves, retained earnings, dividends declared and paid); long-term financing by facility; fixed and intangible assets with schedules; investments by investee
Wholly non-GCC owned	Income tax	Tax-adjusted profit: disallowables by category, depreciation on the tax basis alongside the book basis, provisions by movement, losses carried forward
Mixed Saudi/GCC and non-GCC	Zakat on the Saudi/GCC share, income tax on the non-GCC share	Both of the above, plus an ownership register with effective dates for every transfer
Non-resident with a permanent establishment	Income tax on the PE result	A PE-only ledger, with head office and management charges separated from third-party costs
Non-resident, no PE, receiving Saudi-source payments	Withholding at source by the payer	A payee master carrying residence, treaty position, and the payment category that sets the rate

Why the zakat base is a balance-sheet computation

This is where bookkeepers trained on profit-based taxes go wrong. Under Article 15 of the Implementing Regulations for Zakat Collection, zakat is levied at 2.5 per cent of the zakat base for a Hijri year. Where the financial year is not Hijri, the rate is 2.5 per cent divided by 354 and multiplied by the actual days in the fiscal year, so a Gregorian year end produces a slightly higher effective rate than 2.5 per cent.

The base is built from the balance sheet. Article 23 sets the additions, starting from property rights and their equivalents, property rights within the limits of obligations, and the difference between the amended net result and the net book result after tax. Article 26 sets the deductions, each pointing at a further article defining the evidence needed: investments in domestic enterprises (Article 43), foreign facilities (Article 44), investment funds (Article 45), net fixed and intangible assets (Articles 49 and 50), materials not intended for sale (Article 52), bonds and deeds (Article 55), and statutory deposits (Article 56). Articles 27 and 28 bracket the result with a minimum and a maximum base.

The consequence is that a client's profit tells you almost nothing about their zakat. A loss-making company with substantial capital, reserves and long-term borrowing can carry a material liability, because financing that funded non-deductible assets stays in the base. Explaining that in month eleven is a worse conversation than mapping it in month one.

The adjustments that trip bookkeepers up

Long-term liabilities funded assets that are not deductible. A loan drawn to buy inventory is not the same as one drawn to buy a building. Addition and deduction are tested separately, so the netting a management accountant expects does not happen.

Provisions are not accepted because they are booked. ZATCA's Guideline for Zakat Documents requires notes showing provision movements, the calculation basis, proof of payment by bank voucher where a provision was utilised, and for bad debts written off, administration approval, the entries and a certified accountant's certificate.

Investments deducted without the investee's evidence. For domestic investments the guideline asks for the investee's articles of association and a company identification number proving ZATCA registration. For foreign investments it asks for audited statements, a zakat calculation certificate from a Saudi-licensed chartered accountant, and proof zakat was paid. Practices deduct the carrying value and find in the assessment that the pack was never assembled.

Related party and partner balances treated as ordinary payables. The guideline asks for the agreement, a system statement showing movement and payment per party, payment vouchers with bank statements, and a withholding tax return reconciliation. That last item is where the three computations meet: a balance owed to a non-resident is both a zakat base item and a withholding trigger.

Withholding tax: the monthly rhythm nobody staffs for

Withholding fails quietly, because it is monthly and the ledger evidence arrives late. ZATCA states that it "is imposed on all amounts paid from a source in the Kingdom to non-resident entities that do not have a permanent establishment". The domestic rates, in ZATCA's circular on withholding under double taxation agreements, are: management fees 20 per cent; royalties 15 per cent; any other services from Saudi sources 15 per cent; and 5 per cent for dividends, rent, insurance and reinsurance, loan returns, technical and consulting services, air tickets and air or sea freight, and international telecommunication services.

Two features drive most disputes. The 20 per cent management fee rate and the 5 per cent technical and consulting rate sit four times apart, so how an intercompany recharge is described in the contract and the invoice matters more than the amount. And the residual category is 15 per cent, so a payment fitting no named category defaults upward.

The rhythm is fixed. The monthly return and payment fall within the first ten days of the month following payment: ZATCA's returns calendar shows 10 January for December, and a ZATCA notice set 10 April 2026 for March 2026. The annual withholding return follows within 120 days of fiscal year end. Late payment carries 1 per cent of the unpaid tax for every 30 days of delay.

Treaty relief does not happen by itself. The circular describes a benefit-at-source route requiring a tax residency certificate, an application form, embassy authentication or an apostille, and an undertaking from the payer to settle any tax and penalties; and a refund route requiring the residency certificate, the withholding return with the remittance receipt, and a Chamber of Commerce attested letter confirming the amount was never refunded. The statute of limitation is five years.

VAT, and the ledger that has to serve all three

ZATCA's SME guideline gives the standard VAT rate as 15 per cent, mandatory registration at SAR 375,000 of supplies in twelve months, voluntary registration between SAR 187,500 and SAR 375,000, and monthly filing where revenues exceed SAR 40,000,000 in the past twelve months, quarterly below that. Returns are due by the last day of the month following the period.

The intersection to watch: a payment to a non-resident supplier is often a reverse-charge VAT entry and a withholding event at once, from the same invoice, on two different deadlines. If the reverse charge is posted by the VAT preparer and the withholding left to the tax preparer, one of them is late.

Build the chart of accounts once so all three computations fall out of it:

• Equity at component level, not one "reserves" line: capital, statutory reserve, voluntary reserve, retained earnings, dividends declared and paid, because Article 23 and the document guideline both operate at that level.
• Long-term financing separated from its current portion, by facility, with the purpose recorded, since the guideline asks for the loan agreement and a statement of loan purpose and usage.
• Fixed assets, intangibles and capital work in progress in distinct ranges, with the asset register keyed to the ledger account, because Articles 49 and 50 are evidenced from the asset exhibit.
• Investments analysed by investee and jurisdiction, so Article 43, 44 and 45 evidence packs assemble per investment rather than per balance.
• A counterparty dimension carrying residence and related-party status, making the withholding population extractable monthly instead of discoverable at year end.
• A payment-category dimension on non-resident spend, so the 20 and 5 per cent populations separate at posting rather than in an assessment.

Two record-keeping constraints sit on top. The zakat documents guideline requires audited statements certified by a Saudi public accountant licensed by SOCPA, commercial books maintained in the Kingdom and retained ten years, and documents in Arabic with an official translation where data is recorded otherwise. For electronic records it requires the computer located in the Kingdom, original supporting documents held locally, printouts extracted at least quarterly, and ZATCA access to the systems. A bureau running a client's books on an offshore instance with English-only descriptions has a problem no year-end adjustment fixes.

A year-end preparation procedure

Run this per entity, keyed to the fiscal year end.

1. Minus 90 days. Confirm the ownership profile and pull the shareholder register with effective dates. Any transfer during the year changes the split, and everything else depends on it.
2. Minus 60 days. Confirm the auditor is engaged, with a date. Audited statements certified by a SOCPA-licensed accountant are required support.
3. Minus 30 days. Reconcile the year-to-date withholding population against the supplier master: every non-resident payee, the category, the rate, the return it was reported on, the certificate issued.
4. Plus 2 weeks. Issue the document request, differentiated by ownership profile. A wholly non-GCC-owned entity does not need the equity movement pack; a wholly Saudi-owned one does not need the disallowables analysis.
5. Plus 4 weeks. Close the trial balance and build the zakat base: Article 23 additions and Article 26 deductions, each line carrying the document named in the zakat documents guideline. Flag deductions with no evidence pack as at risk now.
6. Plus 6 weeks. Build the tax computation on the non-GCC share: disallowables by category, depreciation on the tax basis, provisions movement, losses carried forward.
7. Plus 8 weeks. Assemble transfer pricing documentation: the controlled transactions disclosure form, a certified accountant's certificate on adherence to the group policy, arm's length evidence, and the master file, local file and country-by-country report, due within 120 days of year end or with the zakat declaration.
8. Plus 10 weeks. Client review, with both computations, the amount payable and the payment date in one document. Where zakat is large despite a loss, explain the mechanics here, not on the deadline.
9. Plus 120 days. File and pay. ZATCA's calendar shows the zakat declaration and income tax return due within 120 days of fiscal year end, being 30 April 2026 for a 31 December 2025 year end.

Where teams get this wrong

Treating zakat as a tax on profit. It is computed from the balance sheet under Articles 23 and 26, bracketed by a minimum and maximum. A loss-making client can owe a material amount, and the explanation has to come before the invoice.

Deciding the ownership split from the pitch deck. The register, with effective dates, is the source. A share transfer in month seven moves the split and nobody tells the bookkeeper.

Finding non-resident payments at year end. Withholding is monthly and due by the tenth. A year-end sweep surfacing twelve months of undeclared payments produces twelve late returns, each accruing 1 per cent per 30 days.

Describing an intercompany recharge loosely. "Management and technical support" invites 20 per cent on the whole amount. Split the contract and the invoice.

Assuming a deduction survives without its pack. ZATCA can disallow unproven items, and can assess on a deemed basis where books are not maintained or documents are not in Arabic.

What to automate, and what not to

Automate the structure and the extraction. A chart of accounts with equity at component level, a counterparty dimension carrying residence and related-party status, a payment-category dimension on non-resident spend, and an entity register holding the ownership split with effective dates will produce the withholding population every month and the zakat base every year without anyone rebuilding a mapping.

Do not automate the characterisation. Whether a payment is a management fee at 20 per cent or a technical service at 5, whether a provision has crystallised, and whether a treaty position is available on the facts are judgements with documents behind them. A system that guesses produces a confident wrong rate that someone remits. Nor will automation fix a client who cannot produce a loan agreement; it surfaces the gap in month two rather than month eleven, but the call is still yours.

Where a system helps

The work that scales badly in a Saudi bureau is holding, for every client entity, the ownership split as it stands today, the evidence status of each zakat base line, the current month's withholding population, and the 120-day clock, all at once. That is the workflow Daftar is built around: entity-level records carrying ownership and fiscal year end, per-filing checklists with the document named against each line, and evidence held against the engagement. Daftar is not connected to ZATCA and does not file on your behalf.

FAQ

A company is 70 per cent Saudi-owned and 30 per cent US-owned. Does it pay zakat or tax? Both, in proportion. ZATCA applies income tax to shares owned by non-Saudi partners and zakat on the basis of shares owned by Saudi or GCC citizens, so the year-end pack carries a zakat base and a tax computation.

Why does a loss-making client owe zakat? Because the base is built from the balance sheet, not from profit. Capital, reserves, retained earnings and long-term financing are additions under Article 23, and only the deductions listed in Article 26 come out. Articles 27 and 28 set a minimum and maximum base.

When is the withholding return due? Within the first ten days of the month following payment. The annual return is due within 120 days of fiscal year end, and late payment carries 1 per cent of the unpaid tax for every 30 days of delay.

Can we keep the client's books on our own cloud system outside the Kingdom? The zakat documents guideline requires commercial books maintained in the Kingdom, retained ten years, documents in Arabic or officially translated, the computer located in the Kingdom for electronic records, and original supporting documents held locally.
