The Saudi filing calendar: every deadline in one place

Quick answer: The Zakat or corporate income tax declaration is generally due within 120 days of the fiscal year end. An electronic objection to a ZATCA assessment must be filed within 60 days of notification.

Saudi Arabia has no single tax deadline. It has four cycles running at different speeds, administered by one authority, and businesses miss the fast ones while watching the slow one.

The one-line version. Annual Zakat or corporate tax within 120 days of the fiscal year end. VAT monthly or quarterly, by the end of the following month. Withholding tax monthly, by the 10th. In every case the return and the payment share the date.

The four cycles

FISCAL YEAR ENDING 31 DECEMBER 2026 — WHAT LANDS WHEN EVERY MONTH 10th ....... Withholding tax return + payment for the previous month Continuous . E-invoice clearance and 24-hour reporting EVERY QUARTER (or month, if a monthly VAT filer) End of the month following the period end ........... VAT return + payment ANNUAL — WORKING BACK FROM THE DEADLINE 30 APR 2027 Zakat / CIT declaration + PAYMENT DUE <- 120 days after 31 Dec 2026 | MAR 2027 Computation prepared, base and adjustments finalised, cash confirmed available | FEB 2027 Audit fieldwork complete, statements signed | JAN 2027 AUDIT STARTS <- this is the real deadline | DEC 2026 Year-end close: stock count, reconciliations, related-party schedule, disallowables coded THE POINT: 120 days looks generous and is not. Booking the audit in March means signing statements in April and filing the same week. Book it in January.

Plan the cash, not just the filing

Because advance payments are not generally required of most entities for the annual charge, the full Zakat or tax liability falls due on one day, four months after the year end. A company that has spent the year treating the liability as a year-end problem meets it as a single cash event.

The discipline that works is simple: accrue monthly against a computed estimate, keep the estimate current as the year develops, and hold the cash. It is not sophisticated and it removes the most common cause of late payment, which is not unwillingness but timing.

Want one calendar covering every ZATCA obligation?

Chartered Advisory maps your fiscal year to every deadline, runs the monthly and quarterly filings, and works the annual declaration back from the audit rather than forward from the year end.

The mistakes that cost the most

Watching the annual deadline and missing the monthly one. Withholding is the most-missed filing in the Kingdom.
Treating 120 days as four spare months with no audit booked.
Assuming payment comes later than filing. It does not.
Skipping nil returns.
Not accruing for the annual charge and meeting it as one cash event.
Letting an objection window lapse on an assessment you meant to dispute.

The first year is the one that goes wrong

A newly established Saudi entity meets every deadline for the first time in the same twelve months, usually while the finance function is still being built. The pattern is consistent: VAT and withholding start immediately and monthly, while the annual declaration feels distant until the audit reveals it is not.

FIRST-YEAR SEQUENCE — what starts when ON REGISTRATION ZATCA registration and TIN ........ before anything else VAT registration if the threshold is met or expected E-invoicing obligations begin with VAT registration FROM THE FIRST PAYMENT TO A NON-RESIDENT Monthly WHT return + payment by the 10th -> starts immediately, catches most new entities FROM THE FIRST TAX PERIOD VAT return monthly or quarterly, by the end of the following month FROM THE FIRST FISCAL YEAR END Audit booked ...................... month 1 after year end Statements signed ................. month 2 Computation and base finalised .... month 3 DECLARATION AND PAYMENT ........... within 120 days THE TRAP: the annual deadline is the only one that requires work to have started months earlier.

Who owns each deadline

Missed filings in Saudi entities are rarely decisions. They are ownership gaps — the monthly withholding return belongs to nobody in particular because it only matters in months with overseas payments, and the annual declaration belongs to the auditor in everyone's mind until April arrives.

The fix is naming a person against each cycle and a reminder that fires before the work needs to start rather than when it is due. For the annual declaration that reminder belongs in the month the audit should be booked, not in the month the return is filed.

Confirm before you rely on this. Filing cadence thresholds and deadlines are set in each law and its implementing regulations and can differ for particular taxpayer categories. Confirm the current position with ZATCA before acting. Chartered Advisory prepares and supports; a licensed Saudi professional signs where the law requires it.

Questions people also ask

What is the main annual deadline?

The Zakat or corporate income tax declaration and payment, both due within 120 days of the fiscal year end — 30 April for a calendar-year company. Because the declaration is built on audited financial statements, the audit timetable is the binding constraint rather than the filing itself.

Are the return and the payment due on different dates?

No. Across the Saudi regimes the return and the payment share a deadline, and there is no separate later payment window. Advance payments are not generally required of most entities for the annual charge, which means the full liability arrives at once — plan the cash across the year rather than in the final month.

What is the fastest recurring deadline?

Withholding tax. A monthly return with payment by the 10th day of the following month, which comes round twelve times a year and is easy to miss in a month with only one or two payments to non-residents. It is also the deadline most often overlooked by finance teams focused on VAT and the annual declaration.

Do I file if there is nothing to declare?

Yes. Registration creates the filing obligation independently of the numbers, so a nil VAT return and a nil withholding return are both required. Penalties attach to the failure to file rather than to the tax, so a dormant period with no activity still needs the submission.

What happens if I miss a deadline?

Penalties apply automatically and accumulate, and late payment attracts its own charge on top of any late filing penalty. The practical response is to file as soon as possible even if you cannot pay in full, because the two consequences are separate and filing stops one of them growing.
