Ask a founder in Riyadh who is responsible for the VAT return and you usually get a name. Ask who is responsible for the withholding tax return on last month's payment to the software vendor in Dublin, and the room goes quiet.
That silence is the most common problem we see in small and mid-sized companies here. The bookkeeping is often fine. What's missing is one person who looks at the whole year, knows what is due and when, and checks that it actually happened.
The dates themselves are simple
None of the Saudi deadlines are hard to understand. There are just a lot of them, and they belong to different authorities.
As of November 2026, the main ones from ZATCA's own taxpayer calendar look like this:
- VAT. Filed and paid by the last day of the month after the tax period. Companies with taxable supplies above SAR 40 million file monthly, everyone else quarterly (ZATCA SME guide).
- Withholding tax. If you pay a non-resident, the return and the tax are due within the first 10 days of the following month (ZATCA WHT guideline).
- Zakat and corporate income tax. Within 120 days of the year end, so 30 April for a December company.
Then the Ministry of Commerce wants audited financial statements on Qawaem within six months of the year end (Ministry of Commerce). GOSI runs on the payroll cycle. Your MISA licence and CR have their own renewal dates.
A small detail that catches people out. The Q3 VAT deadline this year was 31 October 2026, which was a Saturday. ZATCA's calendar still lists it as the last day.
Where it actually goes wrong
Nobody forgets that VAT exists. The trouble sits in the gaps between people.
The accountant books the invoice from the overseas consultant but doesn't flag it for withholding. The general manager approves a payment early in the month and nobody tells the person filing. The auditor is booked for May because "the deadline is June," and then the zakat return in April has to be filed on draft numbers.
Late VAT filing is not a small fine either. ZATCA reminded businesses in April 2026 that the penalty for filing late runs from 5% to 25% of the tax that should have been declared.
What a virtual CFO adds
A good bookkeeper records what happened. A CFO decides what needs to happen next month and makes sure somebody does it.
For most companies with one Saudi entity and under a few dozen staff, a full-time CFO is hard to justify. A virtual CFO gives you that oversight for a fixed monthly fee. In practice, the work looks something like this:
A one-page compliance calendar for your entity, built from your actual year end, VAT period and licence dates. A short monthly report on what was filed and what is coming up, with anything odd flagged. A review of the management accounts before they go to the owners or to head office. And someone who reads the contract with the foreign supplier before it is signed, not after the first invoice lands.
When the business grows, the role grows with it. Forecasting, cash flow planning, board packs and inter-company billing for a group usually come next.
A quick test
Pull up your last twelve months. Can you show, without digging, that every VAT and withholding return was filed on time and that last year's audit was signed before the zakat return went in? If the answer needs three people and a day of emails, the calendar has no owner yet.
In Saudi Arabia, FCG works as your advisory CFO. The bookkeeping and filings underneath are handled by our associate firm, Gadwalah CPA, so the oversight and the day-to-day work stay joined up.
