WHT Compliance in Saudi Arabia: Withholding, Remittance, Certificates, and Annual Returns

Every entity required to withhold tax must register with ZATCA before making the first WHT-applicable payment. This is not a post-first-payment registration — it must happen first. The obligation to register precedes the obligation to withhold.

Registration is completed through ZATCA’s online portal (Fatoorah / ZATCA e-services). Upon registration, the entity is assigned a tax identification number (TIN) or their existing TIN is linked to the WHT function. Registration for WHT is separate from — but can be combined with — CIT registration. For an entity that is both a CIT taxpayer and a WHT withholder, both registrations should be completed before any taxable activity commences.

The penalty for failing to register before the first payment is SAR 5,000 for most entities and SAR 10,000 for joint stock companies. This is a one-time fixed penalty — but an unregistered entity is also at risk for non-filing penalties on every month in which it should have remitted WHT and did not.

The WHT obligation is triggered at the point of payment to the non-resident — the moment money leaves the Saudi entity for the overseas recipient. The withholding person must apply the correct rate to the gross amount, deduct that amount from the payment, and remit the net amount to the non-resident.

Correct classification is the foundation of correct withholding. Before processing any payment to a non-resident, the finance team must determine: Is this a Saudi-source payment? Is the recipient a non-resident? What category does this payment fall into? What rate applies (5%, 15%, 20%)? Is a DTT applicable, and if so, is treaty documentation in hand?

These questions should be embedded in the accounts payable workflow as mandatory checks — not addressed retrospectively after payment. A payment released without withholding cannot be “corrected” by asking the non-resident to send back the unwithheld amount; the Saudi payer is responsible for the WHT from the date of payment.

Within the first 10 days of the month following any month in which WHT-applicable payments were made, the withholding person must:

• Submit a monthly WHT statement on ZATCA’s prescribed form, through ZATCA’s electronic systems, listing each payment made to a non-resident during that month, the applicable WHT rate, and the amount withheld
• Remit the withheld amounts to ZATCA through the prescribed payment channels (bank transfer, SADAD, or other accepted means)

Both the statement and the remittance must happen within the same 10-day window. A statement without remittance, or remittance without a statement, are each non-compliant. The 10-day window is absolute — it does not extend to the end of the month, to the next working day if the 10th falls on a holiday, or to any other extended deadline unless ZATCA specifically grants an extension.

In months where no WHT-applicable payments were made to non-residents, no monthly statement is required. The obligation is payment-triggered, not calendar-triggered. However, if there is any uncertainty about whether a payment in the prior month was WHT-applicable, file a nil or conservative statement rather than miss the deadline.

In addition to monthly statements, the withholding person must file an annual WHT information return with ZATCA. The deadline is 120 days from the end of the fiscal year — the same deadline as the CIT annual return (approximately 30 April for calendar-year entities). For partnerships, the deadline is 60 days.

The annual information return aggregates all WHT activity during the fiscal year: all payments to non-residents, the applicable categories, the rates applied, and the amounts withheld. It is filed on ZATCA’s prescribed form through the electronic portal.

The annual return serves as ZATCA’s cross-check against the monthly statements filed during the year. Discrepancies between the annual return and the sum of monthly statements will attract ZATCA enquiry. Where corrections are needed — because a monthly statement was incorrect — these should be identified and addressed proactively rather than left for ZATCA to discover during an audit.

A WHT certificate is a document issued to the non-resident recipient confirming that WHT was deducted from their payment and remitted to ZATCA. The non-resident uses this certificate in their home country to claim a foreign tax credit or treaty exemption for the Saudi tax paid on their behalf.

There is no formal ZATCA-mandated template for the WHT certificate in all cases, but the document should contain: the name and address of the Saudi payer; the name and address of the non-resident recipient; the date(s) and amount(s) of payment; the WHT rate applied; the amount withheld; and confirmation of remittance to ZATCA. Some recipients — particularly those in treaty jurisdictions — will have specific requirements from their home tax authority about what the certificate must contain to qualify for foreign tax credit.

Saudi payers should issue WHT certificates as a matter of routine after each payment or at the end of each tax year. Not providing certificates creates friction with non-resident suppliers and partners and may affect their willingness to accept WHT deductions in future contracts.

WHT records must be maintained for at least 10 years from the date of each payment. This is one of the longest retention requirements in the Saudi tax framework. The minimum records per Article 63(9)(c) are: recipient name and address, type and amount of payment, and amount withheld.

In practice, for a defensible audit position, records should also include: the underlying contract; invoices and payment confirmations; the WHT classification rationale; treaty documentation (residency certificates, beneficial ownership confirmation) where treaty rates are applied; and the monthly statement filings and remittance confirmations for each relevant period.

Records relating to matters still under consideration by ZATCA or a competent committee must be kept until final resolution — even beyond the 10-year period. For entities with ongoing or historical ZATCA disputes, the record retention obligation may be open-ended.

Companies must ensure their document management systems are configured for 10-year WHT record retention separately from standard corporate retention policies (which are typically shorter). For businesses making regular cross-border payments over multiple years, the WHT archive becomes a substantial managed collection that requires dedicated attention.

What happens if I discover I under-withheld in a previous month?

If you identify an under-withholding error — wrong rate applied, or a payment missed entirely — the correct action is to self-correct promptly. Amend the relevant monthly statement, remit the shortfall, and pay the applicable delay penalty (1% per 30-day period from the original due date). Voluntary self-correction before ZATCA raises an assessment generally results in a more straightforward resolution than waiting for ZATCA to identify the error in an audit.

Must I file a monthly statement in months when I make no payments to non-residents?

No — the monthly statement obligation is triggered by payments made, not by the calendar. In months where no WHT-applicable payments were made, no statement is required. However, if there is any ambiguity — for example, a payment at month-end where the WHT analysis is still in progress — consider filing a protective statement rather than risking a late filing.

Can the non-resident request a refund of over-withheld WHT directly from ZATCA?

Yes, in principle — where a non-resident has been subject to WHT at the domestic rate but is entitled to a reduced treaty rate, they can apply to ZATCA for a refund of the excess. In practice, this is an administratively intensive process for the non-resident and is far preferable to prevent over-withholding in the first place by obtaining treaty documentation before the payment is made.

Are WHT obligations affected if my company changes its fiscal year?

The monthly WHT remittance obligation continues unaffected by fiscal year changes — it remains tied to the calendar month in which payments are made, not to the fiscal year cycle. The annual WHT information return deadline shifts to reflect the new fiscal year-end (120 days from the new year-end date). During a transition period, a short-period return covers the period between the old and new fiscal year-ends.
