VAT Return Filing in Saudi Arabia: Deadlines, Steps and Fines

If your business is VAT-registered, VAT return filing in Saudi Arabia follows a fixed rhythm: you file a return for every tax period and pay the VAT due by the last day of the month after the period ends. The period is monthly if your annual taxable supplies exceed SAR 40 million, and three months for everyone else. Filing late costs 5% to 25% of the tax you should have declared.

This guide covers who must register, how to tell which tax period applies to you, the filing steps on the Zakat, Tax and Customs Authority (ZATCA) portal, deadlines, common mistakes and how to correct them, the records to keep, and the penalties. Every figure comes from ZATCA's official sources, checked up to October 2026.

Who must register for VAT in Saudi Arabia?

You must register if your taxable supplies exceeded SAR 375,000 over the past 12 months, or are expected to exceed it over the next 12 months. You may register voluntarily once your taxable supplies or taxable expenses reach SAR 187,500 in a 12-month period.

The standard VAT rate is 15%, with some supplies zero-rated and others exempt depending on their type. If you are forming a new company, ZATCA registration is part of our company formation and CR service.

Do you file monthly or quarterly?

The VAT Implementing Regulations set your tax period by the size of your supplies:

• Monthly: if your taxable supplies exceeded SAR 40 million in the previous 12 months.
• Three months: for all other taxpayers, which covers most SMEs.
• Opting into monthly: a business below the threshold may apply to file monthly.
• Returning to quarterly: a business that has filed monthly for two years may apply to go back to three months, provided its supplies are still below the threshold.

You change the period through the "Tax Filing Period Amendment" service on the ZATCA portal. It needs ZATCA's approval, and one of its conditions is that all your previous returns have been filed.

When is the VAT return due, and when must you pay?

Filing and payment share one deadline: the last day of the month after the tax period ends. On 20 October 2026, for example, ZATCA called on businesses with supplies above SAR 40 million to file their September returns, and on all others to file their third-quarter returns, by 31 October 2026.

The same rule applies to monthly filers: the September return, for instance, is filed and paid by 31 October. Do not wait for the last day, because one data query or a late payment puts you in penalty territory.

Tip: set two calendar reminders for every period: one a week after it ends to start reconciling, and one ten days before the deadline to review and approve the return. That turns filing into routine rather than a race against the clock.

How do you file a VAT return on the ZATCA portal?

VAT return filing in Saudi Arabia happens online and is free, through the ZATCA portal or app, and takes minutes when your numbers are ready. The real work happens before you log in.

Before you open the portal

• Reconcile total sales in your invoicing or POS system with your accounts.
• Collect the purchase tax invoices you will claim, and leave out anything without a valid tax invoice.
• Separate standard-rated sales from zero-rated sales, exports and exempt sales.
• Review the credit and debit notes issued during the period.
• Identify imports where you paid VAT at customs, and imported services that fall under the reverse charge.

Filing steps

According to ZATCA's Submit VAT Return e-service:

1. Log in to the ZATCA portal.
2. Go to the "Indirect Tax – Value Added Tax" tab.
3. Open "Returns".
4. Select the return you are filing.
5. Complete the VAT return form: sales by type and their VAT, purchases and deductible input VAT, and any corrections to earlier periods.
6. Submit. You receive a confirmation and the invoice amount by SMS and email, and ZATCA validates the data with AI-powered tools.
7. Pay the amount using the SADAD invoice number, through online banking or an ATM, by the same deadline.

If you had no sales or purchases in a period, file anyway: the regulations require a return for every tax period.

What are the most common VAT return mistakes, and how do you fix them?

Most mistakes happen before the portal, not on it. These come up most often:

• Missing the deadline, or skipping a return for a quiet period.
• Claiming input VAT without a valid tax invoice.
• Mixing up zero-rated and exempt supplies, which sit in different boxes and affect your deductions differently.
• Forgetting the reverse charge on services bought from outside the Kingdom.
• Late credit and debit notes: the 2025 amendments to the regulations require them within 15 days after the end of the month in which the triggering event happened.
• Not reconciling your invoicing system with your accounts, leaving gaps that are hard to explain later.

How do you correct an earlier return?

Under the amended regulations, as explained in ZATCA's April 2025 guideline, if you find you under-declared, correct it in the "Corrections" section of the return for the period in which you found the error. If you over-declared, you can adjust it in any later return within the statutory time limit.

Do not put corrections off: the fine for an incorrect return is 50% of the difference, although ZATCA may waive or reduce it under rules approved by its board.

Which records must you keep, and for how long?

Keep invoices, books, records and accounting documents for at least six years from the end of the tax period they relate to. Records for capital assets must be kept longer: the asset's adjustment period plus five years.

• Keep records in Arabic, and issue tax invoices in Arabic, with any translation alongside.
• Keep them in the Kingdom, on paper or electronically with access from inside the Kingdom.
• Failing to keep them for the required period can cost up to SAR 50,000.

The invoice itself also has e-invoicing requirements, which our guide to ZATCA e-invoicing Phase 2 explains.

What are the VAT penalties in Saudi Arabia?

These are the main fines in ZATCA's VAT violation fines table, last updated in August 2026:

A fine can be doubled if the same violation is repeated within three years of the final decision. ZATCA may also offset any refund due to you against fines or other amounts you owe.

Is the fines exemption initiative still running?

Yes, until 31 December 2026. ZATCA extended the initiative for six months from 1 July 2026. It covers fines for late registration, late payment and late filing, and VAT return correction fines. To benefit, you must be registered, file all outstanding returns, and pay the principal tax or apply for an instalment plan while the initiative is open.

Warning: the initiative does not cover fines linked to any return due after 30 June 2026, or tax evasion penalties. A late Q3 2026 return, for example, is not covered.
