VAT registration in Saudi Arabia: threshold, steps and certificate

VAT registration in Saudi Arabia is mandatory once your taxable supplies over the past 12 months exceed SAR 375,000, or are expected to over the next 12, and optional from SAR 187,500 [1]. You apply online within 30 days of the month-end check, and ZATCA issues a certificate showing your VAT number and effective date [2].

This guide covers the monthly threshold test, the portal steps, the certificate and the first obligations that follow. It is general information, not tax advice: confirm a specific case with ZATCA or a licensed tax adviser.

Who must register for VAT, and who may?

The amounts come from the GCC Unified VAT Agreement, and ZATCA's Implementing Regulations set out how and when to apply [1][2].

ZATCA's guidance spells out what counts towards the SAR 375,000. Taxable supplies include zero-rated ones, but exclude exempt supplies such as qualifying residential rent, supplies outside the scope of VAT, and proceeds from selling capital assets held for long-term use [1]. Article 6(5) of the regulations makes the same point about capital assets [2].

Individuals who carry on an economic activity in the Kingdom register too; ZATCA runs a separate e-service for them, with the same thresholds [4]. An employee is not carrying on an economic activity for the work done under an employment contract (Article 9(6)) [2].

How to run the threshold test each month

The test is done at the end of every calendar month, and it has two sides [2]:

1. Look back (Article 3). Add up your taxable supplies for the 12 months just ended. If the total exceeds the mandatory threshold, apply within 30 days of the month's end. Registration takes effect from the start of the month after the one in which you apply.
2. Look ahead (Article 4). Estimate your taxable supplies for the next 12 months, counting signed contracts and firm orders. If the estimate exceeds the threshold, apply within 30 days of the month's end. Registration takes effect from the start of the first month in which supplies are expected to cross it.

On request, ZATCA can move the effective date later, but not beyond the start of the month after the application, or earlier, to a date when you were already eligible (Article 6(2) and (3)) [2].

Illustrative example: a catering kitchen in Dammam

Illustrative example. A catering kitchen in Dammam opened in November 2025. Its monthly taxable sales grew from SAR 25,000 to SAR 45,000. In June 2026 it sold an old delivery van for SAR 40,000, which does not count because it is a capital asset [1].

The look-ahead test is the one that usually catches a growing business first. Here, an owner who only watched the past 12 months would have waited until the end of September 2026 and applied in October, about four months later than the rules required. From the end of May, the kitchen had also passed SAR 187,500, so it could have registered voluntarily even without the estimate.

VAT registration in Saudi Arabia on the ZATCA portal, step by step

Registration is free and done online [3]. ZATCA's user guide sets out the steps for businesses [5]:

1. On zatca.gov.sa, open E-Services and choose VAT Registration for Businesses.
2. Log in with the username and password for companies and establishments; individuals log in through Nafath, the national single sign-on.
3. Enter the verification code sent by SMS to your mobile.
4. From the side menu, choose VAT Services, then Register in VAT.
5. Complete Taxpayer Details.
6. Enter your sales and purchases in Financial Information.
7. Attach the supporting documents.
8. Complete the Financial Representative section.
9. Add optional documents, review the summary and submit.

A window confirms the submission, and ZATCA sends an SMS and email when the application is complete; the output is your VAT number [3][5]. Sole traders and other individuals use the separate VAT Registration for Individuals e-service [4].

What the application must contain

Article 8(2) lists the minimum information: your legal or personal name and personal details, the actual address of your residence or place of business, an email address, any electronic identification number ZATCA has issued, your commercial registration number if you have one, the value of your annual supplies or expenses, and the effective date you are asking for [2]. ZATCA may ask for documents that support these details and must give you at least 20 days to provide them. It may reject an application that is inaccurate, or from someone not entitled to register (Article 8(3) and (4)) [2].

When registration takes effect, and the VAT you paid before it

The effective date matters twice: you charge VAT on your sales from that date, and it sets how far back you can recover VAT on costs.

• Services bought in the six months before the effective date can qualify for input VAT deduction if they were for your taxable business, were not resupplied or fully used before registration, and are not blocked under Article 50 (Article 49(2)) [2].
• Goods bought or imported before registration can qualify if they are for the taxable business and were not resupplied or used before the registration date. For capital assets not yet fully depreciated, the deduction is capped by their net book value on that date (Article 49(3) and (4)) [2].
• Contracts that straddle the date: if you invoiced or were paid before registration but the supply happens afterwards, VAT is due on the date of supply. For a continuous supply, the part delivered before registration is not taxed (VAT Law, Article 21) [7].

The VAT registration certificate: what it shows and where it goes

Once ZATCA accepts the application, it issues a registration certificate that shows the date registration takes effect and your tax identification number (Article 8(5)) [2]. The VAT Law requires a certificate for every registered person (Article 3(3)) [7].

• Display it. A resident registered business must display the certificate where the public can see it, at its head office, its branches and its online stores (Article 8(8)) [2]. For a website or app, that means a page customers can open.
• Reprint it. The certificate is placed on ZATCA's portal when it is issued, and the free Print VAT Certificate e-service lets you download a fresh copy at any time [6].
• Keep it current. Tell ZATCA about any change to the details in your application within 20 days (Article 8(7)) [2].

Suppliers and customers will ask for a copy, so keep the PDF where your finance and sales teams can find it.

Your first obligations after registration

Registration starts several duties at once. Each one has its own rules; this list is a starting point.

• Charge VAT at the standard 15% on taxable supplies from the effective date (VAT Law, Article 2) [7].
• Show your VAT number on tax invoices and in VAT correspondence with ZATCA (Article 57) [2].
• Invoice electronically. ZATCA enforced the first phase of e-invoicing on 4 December 2021 for all resident taxpayers, so your invoices must come from a compliant solution [8].
• File returns. Your tax period is quarterly unless your taxable supplies exceeded SAR 40 million in the previous 12 months; smaller businesses may ask to file monthly (Article 58). Returns and payment are due by the last day of the month after each period (Articles 59 and 62) [2].
• Keep records for at least six years from the end of the tax period (Article 66) [2].

What late registration costs

The VAT Law fines anyone who does not apply within the regulatory period SAR 10,000 (Article 41) [7]. That is only the start:

• ZATCA can register you without an application, with effect from the date set by Articles 3 and 4, so VAT becomes due on your sales from that date (Article 6(1)) [2].
• Where a person failed to register, ZATCA may issue or amend assessments for up to 20 years from the end of the calendar year concerned, instead of the usual five (Article 64(3) and (4)) [2].
• Issuing a tax invoice while unregistered carries a fine of up to SAR 100,000 (VAT Law, Article 44) [7].

Tax groups and deregistration in brief

Two or more legal persons that meet the conditions of Article 10 can register as a VAT group [2]. The group is treated as one taxable person, and every member is jointly and severally liable for the group's VAT for the time it is a member (VAT Law, Article 4) [7].

Deregistration has its own rules in Article 13 [2]. You must apply to cancel within 30 days if you stop your economic activity, or if, as a resident, your supplies or expenses have fallen below the voluntary threshold under the conditions of Article 13(3). You may apply if your supplies in the past 12 months did not exceed the mandatory threshold and are not expected to over the next 12. A voluntary registrant cannot apply in its first 12 months unless it stops trading, and records must still be kept for the full retention period after deregistration.

A checklist before you press submit

Have each item ready before you start the application.

1. Past 12 months of taxable supplies, excluding exempt, out-of-scope and capital-asset sales
2. Next 12 months estimated from signed contracts and firm orders
3. The month-end that triggered the test, and the 30-day deadline that follows
4. Commercial registration number, portal login, or Nafath for individuals, and a mobile for the code
5. Sales and purchase figures for the Financial Information section
6. Financial representative details
7. The effective date you will ask for, and the reason
8. An Arabic invoice template ready to show your VAT number from day one

Your next step

Take your last month-end and run both tests: the past 12 months of taxable supplies and an honest estimate of the next 12. Write the figures and the date in one place. If either is above SAR 375,000, start your VAT registration in Saudi Arabia on ZATCA's portal this week rather than at the end of the 30 days, so the certificate and your invoicing are ready on the effective date.
