Saudi Arabia income tax 2026: who pays 20%, and the 183-day or 30-day residence test

Saudi income tax does not begin with an individual's salary but with a kind of activity and a kind of owner. ZATCA, the Zakat, Tax and Customs Authority, defines it in its simplified guideline as a direct tax on resident capital companies regarding the shares owned by non-Saudi persons or by persons producing oil and hydrocarbons, on non-Saudi resident natural persons who practise an activity in the Kingdom, and on non-residents who practise through a permanent establishment or draw taxable income from sources in the Kingdom without one. People working in natural gas investment and in oil and hydrocarbons also come under it. Residence is a short test: a natural person is resident for a Zakat year with a permanent dwelling in the Kingdom and at least 30 days there, or with at least 183 days there. The texts we read do not offer a progressive personal scale. They name one general rate, and they leave much of what an ordinary employee wants to know unsaid, which we point out below.

One rate: 20%, with a separate one for oil

That figure comes from a chart in the guideline, which shows the three boxes above around one 20% label. There is no bracket and no personal allowance in that chart, so we show no scale. ZATCA's regulations page states that taxable activity covers all forms of activity: commercial, industrial, agricultural, service, banking, insurance, investment, transport, leasing and professional work for profit. Two things fall outside for individuals: opening bank accounts of any type, and a resident natural person trading shares of companies listed on the Saudi capital market.

A non-resident with Saudi-source income and no permanent establishment also falls within the tax, and ZATCA's withholding guideline deals with it through withholding at the payer's end. A natural person only has to withhold on payments made for a commercial activity in the Kingdom. Payments to non-residents for personal use are not caught.

What these texts say about employees, Saudis and Zakat

Readers often arrive here asking whether a salary is taxed. The ZATCA texts we read list who is subject to income tax, and that list does not name employees. It does not state outright that wages are exempt either, so we word this carefully and stop short of writing that there is "no tax on salaries". We did not manage to open the Income Tax Law on the site of the Bureau of Experts, which refused the connection, nor did the FAQ page show its answers to our reader. Saudi nationals are not on the list when they are residents; the withholding guideline refers to "a natural person subject to Zakat collection" as a separate position, and Zakat is a different system that this page does not cover. For a contract or a business, ask ZATCA, since this page cannot replace that answer.

Two thresholds: 183 days, or 30 with a home

The two routes sit a long way apart. Without any home, it takes 183 days. With a permanent dwelling in the Kingdom, 30 days are enough, and that is the trap for someone who keeps a flat in Riyadh and visits each quarter. Being resident does not by itself mean you owe income tax, as the guideline says clearly: a resident person has to withhold where relevant "regardless of whether they are subject to tax or not". The test decides your status, and the list above decides the tax.

Certificate of residence for individuals

ZATCA offers an electronic service for a Tax Residency Certificate for individuals residing in the Kingdom. The service page repeats the same two figures: a person with a permanent residence is allowed 30 days, and those without one 183 days. It asks for a valid passport, a proof of residency and an employment verification letter. This is the document a foreign authority is likely to want if you claim treaty benefits. The page does not give a fee or a processing time, so we give none.

Filing and penalties for those who are in scope

A person subject to income tax must register with ZATCA before the end of their first fiscal year. The guideline sets the fine for failing to do so at SAR 1,000 for a natural person. For a late return, the penalty is the higher of 1% of total revenue, up to SAR 20,000, and a percentage of the unpaid tax that grows with the delay.

Late payment costs a further 1% of the unpaid tax for every 30 days, from the due date to the date of payment, and a fine of 25% of the tax difference applies for false information or fraud meant to evade tax. Among the exemptions the guideline lists are capital gains on securities traded on the Saudi Stock Exchange, under conditions, and gains on property other than business assets.

Why a low-tax stay still needs a count

Your count matters even if you never owe Saudi income tax, for two reasons. First, the residence test underlies the certificate you may need for a treaty claim. Second, the country you came from applies its own rules to you. A move to Riyadh does not switch off the UK's Statutory Residence Test, and a US green card makes you resident with no day count. We have not reviewed Saudi treaties here.
