Calculating the Saudi Zakat base: additions and deductions
Zakat is charged at 2.5 per cent — a rate low enough that businesses stop thinking about it. The base it applies to is where the money actually is, and it behaves in a way that surprises anyone expecting a profit measure.
How the base is built
The rules below come from the Implementing Regulation for Zakat Collection, Ministerial Resolution No. 1007 dated 19/8/1445H (29 February 2024), which supersedes the earlier regulation and governs fiscal years beginning on or after 1 January 2024. Zakat is charged at 2.5 per cent of the zakat base, and the base is net worth as adjusted by that Regulation — not profit. That single distinction explains most of what follows, including why a loss-making company can still owe zakat.
The logic is consistent once you see it: Zakat targets circulating wealth. Money tied up in long-term operating assets is deducted; money funding the business and available to it is included. That single idea explains most of the additions and deductions without memorising them.
How it behaves
| What you do | Effect on the base |
|---|---|
| Retain profits instead of distributing | Increases — reserves and retained earnings are in the base |
| Inject equity | Increases |
| Buy substantial fixed assets | Decreases — net fixed assets are deductible |
| Take a long-term shareholder loan | Generally increases, as a source of funds |
| Make a loss | Reduces retained earnings, but the base rarely disappears |
| Hold large receivables and inventory | Neutral directly, but they are what the funds financed |
Preparing the declaration
- Start from audited financial statements. The declaration is built on them and ZATCA works from them.
- Identify the lunar-year holding condition for the items where it applies.
- Support every deduction. Net fixed assets and long-term investments need to be evidenced, not asserted.
- Apply the ownership percentage last, after the base is computed.
- File within 120 days of the fiscal year end, with payment.
- Keep the working paper — the base is the item most often queried and reconstructing it later is painful.

Avail our Saudi tax servicesThe mistakes that cost the most
- Expecting Zakat to follow profit. It follows funding.
- Rolling forward a prior-year computation built on superseded Regulations.
- Deducting fixed assets gross rather than net.
- Accumulating reserves without modelling the compounding effect.
- Applying the ownership split to the wrong figure.
- Keeping no working paper for the item most likely to be queried.
A worked base
What this means for how you finance the business
Zakat is one of the very few charges that responds to balance sheet decisions rather than to transactions, and it does so every year rather than once. Three consequences follow.
- Distribution policy has a price. Retained profits stay in the base indefinitely, so accumulation compounds the liability.
- Capital-intensive businesses fare differently. Net fixed assets come out, so a manufacturer and an asset-light services firm with identical equity can face very different outcomes.
- Shareholder funding is not neutral. A long-term shareholder loan generally sits in the base as a source of funds, so the choice between equity and shareholder debt is not purely a corporate law question.
None of these are aggressive positions. They are ordinary structuring decisions that happen to have a recurring 2.5 per cent attached, and they are made long before anyone opens the declaration.

Questions people also ask
What exactly is the Zakat base?
Broadly, the sources of funds financing the business that have been held for a lunar year — capital, retained earnings, reserves, provisions and long-term liabilities — reduced by deductible items, principally net fixed assets and certain long-term investments. It is a balance sheet measure of what is funding the enterprise, not a measure of what it earned.
Why does my Zakat go up when I retain profits?
Because retained earnings and reserves form part of the base. A profitable Saudi-owned company that accumulates rather than distributes is enlarging the amount its 2.5 per cent is charged on each year. That is a real structuring consideration rather than an accounting curiosity, and it should be modelled before a distribution policy is set.
Can Zakat be due when the company made a loss?
Yes. The base is what funds the business rather than what it earned, so a well-capitalised company with a poor year can still have a substantial base. This is the single largest difference from corporate tax and the reason a mixed-ownership company cannot plan both sides from one forecast.
Do fixed assets reduce the base?
Net fixed assets are generally deductible, on the reasoning that funds tied up in long-term operating assets are not circulating wealth. This is why a capital-intensive manufacturer and an asset-light services firm with identical equity can face very different Zakat outcomes.
Which rules apply to my year?
The Zakat Regulations were superseded for fiscal years beginning on or after 1 January 2024, so a current-year computation should be built on the newer regulations rather than on a prior-year working paper carried forward. Check which version governs your specific fiscal year before rolling anything forward.
