Saudi corporate income tax: the 20 per cent, and the 120 days
Saudi corporate income tax is a flat 20 per cent, and almost every difficulty with it lies somewhere other than the rate — in who is inside the charge, what the base is after adjustment, and a 120-day filing window that arrives before many audits are finished.
Who is inside the charge
| Person | Position |
|---|---|
| Resident company, non-Saudi / non-GCC shareholders | CIT at 20% on their proportionate share of taxable income |
| Resident company, Saudi / GCC shareholders | Zakat instead, on their share — see which regime applies |
| Non-resident with a permanent establishment in the Kingdom | CIT on income attributable to that PE |
| Non-resident without a PE, receiving Saudi-source payments | Withholding tax at source instead |
| Individuals on salary | No personal income tax — this has not changed |
| Oil and hydrocarbon production | Separate regime, progressive rates far above 20% |
From accounting profit to taxable income
Two lines deserve attention before the year closes rather than after. Thin capitalisation turns on the debt-to-equity position, so a group funding its Saudi subsidiary by loan rather than equity should model the disallowance before drawing the facility. And related-party pricing must satisfy the arm's length principle, with transfer pricing documentation where the thresholds are met.
The 120-day window
| Fiscal year end | Return and payment due |
|---|---|
| 31 December 2026 | 30 April 2027 |
| 31 March 2027 | 29 July 2027 |
| 30 June 2027 | 28 October 2027 |
Permanent establishment: the trap for foreign groups
A non-resident company with no Saudi entity can still be taxable here if its activities create a permanent establishment — a fixed place of business, a branch, a construction or installation project of sufficient duration, or a dependent agent habitually concluding contracts on its behalf.
Where a PE exists, income attributable to it is taxed at 20 per cent and a return is due. Where it does not, Saudi-source payments to the non-resident are dealt with by withholding at source instead. Getting this wrong in the wrong direction is expensive both ways — an unrecognised PE means unfiled returns, and an over-cautious assumption of PE means tax paid that was never due.
Chartered Advisory tests the permanent establishment position, prepares the tax computation from audited statements, and files the ZATCA declaration within the 120-day window.
Avail our Saudi tax servicesThe annual routine
- Register with ZATCA and obtain the tax identification number before anything else.
- Schedule the audit backwards from the 120-day deadline, not forwards from the year end.
- Code disallowables during the year — fines, non-business expenditure, excess interest — rather than reconstructing them at filing.
- Document related-party pricing contemporaneously.
- Track brought-forward losses and the utilisation limit.
- Settle the liability by the filing date; there is no separate later payment date.
- Diarise the objection window if an assessment arrives — it is short.
The mistakes that cost the most
- Treating 120 days as four spare months when the audit has not been booked.
- Funding the subsidiary with debt without modelling thin capitalisation.
- Assuming no Saudi entity means no Saudi tax. A PE can arise without one.
- Applying 20 per cent to the whole profit in a mixed-ownership company.
- Expecting to carry a loss back. Forward only.
- Letting the objection window lapse on an assessment you intended to dispute.

Questions people also ask
What is the corporate tax rate in Saudi Arabia?
20 per cent of net adjusted profit, applied to the non-Saudi and non-GCC ownership share and to permanent establishments of non-residents. Saudi and GCC-owned shares attract Zakat at 2.5 per cent of the Zakat base instead. Oil and hydrocarbon production sits under a separate regime with progressive rates far above 20 per cent.
When is the corporate tax return due in Saudi Arabia?
Within 120 days of the fiscal year end, with the tax settled by the same date — 30 April for a calendar-year company. Because the declaration is built on audited financial statements, the practical constraint is the audit timetable: working back from 30 April means booking the audit in January rather than March.
Can I fund my Saudi subsidiary with a shareholder loan?
You can, but model the thin-capitalisation position first. Debt-to-equity ratios above roughly 3:1 put the excess interest at risk of disallowance, so a structure that looks efficient on paper can lose the deduction it was built for. Related-party interest also has to satisfy the arm's length principle.
Do losses carry forward?
Indefinitely forward, never back, and subject to an annual utilisation limit. This is one of the asymmetries between the two regimes: losses shelter corporate tax on the foreign share but do not remove Zakat on the Saudi share, because Zakat is charged on net worth rather than on profit.
Can I be taxed in Saudi Arabia without a Saudi company?
Yes, if your activities create a permanent establishment — a fixed place of business, a branch, a construction or installation project of sufficient duration, or a dependent agent habitually concluding contracts for you. Income attributable to that PE is taxed at 20 per cent and a return is due. Without a PE, Saudi-source payments are generally dealt with by withholding at source instead.
