Income Tax on Variable Salaries in Saudi Arabia: Practical Steps to Determine the Final Amount

The basic salary is not the only component that enters into income tax calculation. Many employees receive housing allowances, performance bonuses, sales commissions or even annual allowances. Each of these elements is classified as “variable salary” and requires special treatment when preparing the tax return.

What are variable salaries?

Variable salaries are defined as any payments that are not granted regularly and fixed every month, but vary according to certain conditions such as achieving a sales target, completing a project or adjusting the cost of living. They include:

• Housing and transport allowances.
• Annual or semi-annual performance bonuses.
• Commissions calculated as a percentage of sales value.
• Year-end bonuses or promotion bonuses.
• Education and healthcare allowances that are paid based on employee needs.

From a tax perspective, these payments are treated as taxable income, with limited exemptions according to Saudi regulations.

General rules for income tax in Saudi Arabia

Saudi tax law imposes income tax on non-Saudi individuals, while citizens are exempt from this tax. If you are a non-Saudi working in the kingdom, all sources of your income—basic and variable—fall within the tax base. The tax rate on non-Saudi individuals’ income is a flat 20 %, and it does not apply to salaries paid to citizens.

There is an annual exemption limit that is set each year. If your total annual income (including variable salaries) is below this limit, no tax is imposed. The current limit for 2025 is 144 000 SAR, but you should verify the official figure before filing your return.

Steps to calculate tax on variable salaries

Here is an ordered method to determine whether you need to pay tax on variable salaries and how to calculate the amount due.

1. Gather all annual income references. Start with the basic salary then add every allowance, bonus, commission and allowance you received during the financial year.
2. Check the allowed exemptions. Some allowances may be partially exempt (for example, housing allowance if it equals or is below the published limit). Reviewing the exemption table in the tax law ensures that non-taxable amounts are not included.
3. Calculate total taxable income. Subtract the exemption value from the total income, and you will obtain the net income subject to tax.
4. Compare the net amount with the annual exemption limit. If the net is below the limit, no tax is payable and there is no need to file a return. If it exceeds the limit, proceed to the next step.
5. Apply the tax rate. Tax is 20 % of net taxable income. Multiply the net by 0.20 to obtain the tax amount due.
6. Include the amount in the tax return. In the income tax return form, you will be asked to enter basic salary and allowances separately. Ensure all fields are filled accurately to avoid any later audit.

Practical examples

Let us look at three scenarios that illustrate the differences in calculating tax on variable salaries.

Example 1: Non-Saudi employee receiving a fixed salary and housing allowance

Basic salary: 120 000 SAR per year.
Housing allowance: 30 000 SAR (partially exempt at 50 %).

Total before exemption = 150 000 SAR.
Exemption on housing allowance = 30 000 × 0.5 = 15 000 SAR.
Net taxable income = 150 000 – 15 000 = 135 000 SAR.

Annual exemption limit = 144 000 SAR; since 135 000 < 144 000, no tax is due.

Example 2: Sales consultant receiving commissions

Basic salary: 80 000 SAR.
Sales commissions: 50 000 SAR (no exemption).
Year-end bonus: 10 000 SAR.

Total = 140 000 SAR.
Taxable net income = 140 000 SAR (no exemptions).
Annual exemption limit = 144 000 SAR, net is still below; no tax.

Example 3: Technical engineer with quarterly incentives

Basic salary: 100 000 SAR.
Quarterly incentives: 25 000 SAR (paid every three months).
Children’s education allowance: 12 000 SAR (fully exempt).

Total = 137 000 SAR.
Exemption on education allowance = 12 000 SAR.
Net taxable income = 125 000 SAR.

Annual exemption limit = 144 000 SAR; no tax.

The examples show that most variable salaries do not result in tax payment as long as total income does not exceed the specified limit. However, if income rises above 144 000 SAR, tax is applied immediately at 20 %.

Tips to avoid common mistakes

• Record every income source accurately. Relying only on the payslip may overlook separate allowances or commissions.

• Check annual exemptions. Updating the rules each year may change the amount of available exemptions.

• Use accounting software. Applications such as Zoho Books or QuickBooks facilitate gathering and summarising variable salaries.

• Consult a tax expert. When transactions are complex (for example, international allowances or temporary employment contracts), the adviser ensures the return is correct.

• File the return on time. Delay may lead to penalties that are not offset by any tax benefit.

Following these steps puts you in control of the tax flow on income and reduces the risk of audit. Do not hesitate to review the Ministry of Finance guide or consult a specialist accountant if you encounter any ambiguity.
