How to File an Income Tax in Saudi Arabia

Understanding how to file an income tax return is one of the most important financial obligations for non-Saudi investors, foreign companies, and businesses operating in the Kingdom. The process is governed by the Zakat, Tax and Customs Authority (ZATCA), and getting it wrong — even accidentally — can lead to penalties that compound quickly. Whether you are a first-time filer or a seasoned business owner looking to sharpen your compliance, this guide walks you through everything in plain language.

At OMK, a fully licensed certified accounting office, we work with clients across multiple sectors who face exactly these questions every year. The rules around income tax in Saudi Arabia are more nuanced than most people expect, and the gap between knowing the law and correctly applying it is where most mistakes happen. Our goal here is to close that gap for you.

What Is Income Tax in Saudi Arabia?

Income tax in Saudi Arabia is a direct tax levied on the taxable income of non-Saudi individuals and foreign-owned entities conducting business within the Kingdom. It is administered exclusively by ZATCA and operates under the Income Tax Law issued by Royal Decree M/1. Importantly, Saudi nationals and GCC citizens are generally subject to Zakat rather than income tax — a distinction that matters enormously when structuring a business or a partnership.

The system applies to capital shares owned by non-Saudis in any business entity registered or operating in Saudi Arabia. Even if a company is primarily Saudi-owned, the foreign partner’s share of taxable income is still subject to income tax at the applicable rate. What’s interesting here is that the tax base is determined not by nationality of the company itself, but by the nationality of its shareholders — which catches many new investors off guard.

Value added tax operates as a separate mechanism entirely, collected at the point of sale on goods and services at a standard rate of 15%. Selective tax similarly applies to specific product categories like tobacco, energy drinks, and carbonated beverages. Neither of these is the same as income tax, though all three are administered by the same authority and are often confused by businesses that are new to Saudi tax compliance.

What Are the Rules and Conditions of Income Tax in Saudi Arabia for Residents and Companies?

1. Any non-Saudi individual or entity generating income from a source within Saudi Arabia is subject to income tax on that income, regardless of where the business is incorporated.
2. Foreign companies with a permanent establishment in the Kingdom — such as a branch, office, or project — must register for a tax registration number with ZATCA before commencing operations or within 30 days of becoming liable.
3. Mixed-ownership companies, where both Saudi and non-Saudi partners hold shares, must separate each partner’s proportional income: the Saudi share is subject to Zakat while the foreign share is subject to income tax.
4. Non-resident entities that earn income from Saudi Arabia without maintaining a permanent establishment are subject to withholding tax on specific income categories, including dividends, royalties, technical fees, and management fees.
5. All taxable entities must maintain proper accounting records in Arabic, prepared in accordance with Saudi Generally Accepted Accounting Principles, and these records must be retained for a minimum of ten years.
6. Failure to register or late registration can trigger administrative fines, and repeated non-compliance may result in ZATCA conducting a mandatory tax assessment based on estimated income.

Income Tax Rates for Residents and Companies

The standard income tax rate for non-Saudi individuals and foreign companies in Saudi Arabia is a flat 20% of net taxable income. This rate applies uniformly regardless of the size of the company or the amount of profit, which keeps the calculation relatively straightforward compared to progressive tax systems used in other countries.

There is, however, an important exception for companies operating in the oil, hydrocarbon, and natural resource sectors. These entities face a significantly higher tax rate, which can reach up to 85% depending on the nature of the concession agreement and the specific extraction activities involved. For the vast majority of businesses — trading companies, service providers, technology firms, construction contractors — the 20% flat rate is what applies.

Here’s the thing most business owners miss: the taxable base is net income, not gross revenue. That means allowable deductions — including operating expenses, depreciation, and certain financial costs — reduce the amount you actually pay tax on. Proper bookkeeping, which is something OMK’s certified accounting office handles for clients on a monthly basis, directly impacts how much tax you owe at year-end.

How Is Income Tax Calculated in Saudi Arabia?

• Start with gross revenue: total all income earned from business activities conducted within or sourced from Saudi Arabia during the fiscal year.

• Deduct allowable business expenses: this includes salaries, rent, utilities, depreciation of fixed assets, and other costs directly related to generating taxable income — expenses must be documented and reasonable.

• Subtract any carried-forward losses from previous years, as Saudi tax law permits loss carryforwards for up to five years under specific conditions.

• Apply the 20% flat income tax rate to the resulting net taxable income figure to arrive at your tax liability.

• Account for any withholding tax already deducted at source during the year, which can be credited against your final annual tax bill.

• Calculate any penalties or interest due if previous payments were late or if a prior-year assessment resulted in additional tax owing.

• The final figure is what must be paid to ZATCA, and payment must be accompanied by the zakat and income payment code issued through the authority’s online portal.

What Income Is Subject to Income Tax in Saudi Arabia?

1. Profits derived from commercial, industrial, or professional activities carried out within the Kingdom by non-Saudi entities or individuals.
2. Income earned by non-residents from Saudi sources, including dividends paid by Saudi companies, royalties, and technical service fees — all subject to withholding tax at rates ranging from 5% to 20%.
3. Capital gains arising from the disposal of assets located in Saudi Arabia, including real property and business assets.
4. Income from contracts executed wholly or partially within Saudi Arabia, including construction, consulting, and engineering projects.
5. Rental income from real estate or equipment situated within the Kingdom and received by a non-Saudi entity.
6. Any other income that ZATCA determines has a Saudi source, based on where the economic activity that generated the income took place.

Types of Income Exempt from Income Tax

• Dividends received by a Saudi company from another Saudi company in which it holds at least 10% of shares for a minimum of one year — these are exempt under the participation exemption rule.

• Income earned by international airlines and maritime shipping companies on a reciprocal basis, where the other country grants equivalent treatment to Saudi carriers.

• Capital gains from the disposal of shares listed on the Saudi Exchange (Tadawul), subject to certain holding period conditions.

• Salaries and employment income earned by Saudi nationals, which fall under the Zakat regime rather than income tax.

• Income earned by entities established under international agreements to which Saudi Arabia is a signatory, where such agreements explicitly grant a tax exemption.

• Certain government-related income and income from activities specifically exempted by Royal Decree on a case-by-case basis.

How to File an Income Tax Return

• Register with ZATCA’s online portal (Fatoora / Zatca.gov.sa) and obtain your tax registration number — this is a prerequisite before any return can be submitted.

• Prepare your financial statements for the fiscal year, ensuring they are audited and signed off by a licensed external auditor recognized by the Saudi Organization for Certified Public Accountants.

• Complete the income tax return form electronically through the ZATCA portal, entering all income, deductions, and credit figures accurately in line with your audited accounts.

• Attach supporting documentation: audited financial statements, a detailed schedule of revenues and expenses, and any transfer pricing documentation if related-party transactions exist.

• Generate the zakat and income payment code from the portal and use it to process your tax payment through an approved banking channel before the deadline — typically 120 days after fiscal year-end.

• Submit the return electronically by the due date; late submission triggers an automatic penalty equal to 1% of total revenue for each month of delay, capped at 20% of the tax due.

• Retain all filed returns, financial statements, and supporting records for a minimum of ten years, as ZATCA has the right to audit any tax year within that period.

Knowing how to file an income tax return correctly from the first step is what separates compliant businesses from those that face avoidable penalties. OMK’s certified accounting office offers full support for each stage of this process, from initial registration through to final submission.

Frequently Asked Questions

Who Is Required to File an Income Tax Return in Saudi Arabia?

Any non-Saudi individual or foreign-owned company that earns taxable income from Saudi sources is legally required to file an annual income tax return with ZATCA. This includes wholly foreign-owned entities, mixed Saudi-foreign partnerships (on the foreign partner’s share), and non-resident companies with a permanent establishment in the Kingdom. Saudi nationals and GCC citizens are generally subject to Zakat rather than income tax, though mixed entities must handle both obligations simultaneously.

What Is the Deadline for Submitting an Income Tax Return to ZATCA?

The income tax return must be filed within 120 days of the end of the taxpayer’s fiscal year. For companies operating on a calendar-year basis, this means the deadline falls at the end of April. ZATCA does not grant automatic extensions, so late filing — even by one day — triggers penalties. It is strongly advisable to begin preparing your financial statements well before year-end to avoid a last-minute rush that increases the risk of errors.
