VAT Rules for Saudi SMEs in 2026: Rates & Thresholds

Small and medium-sized enterprises in Saudi Arabia continue to operate under a standard value-added tax (VAT) rate of 15% on most taxable goods and services in 2026, with clear rules governing when a business must register, how often it files, and what its invoices must include.

Registration becomes mandatory for resident businesses once taxable supplies reach SAR 375,000 over any 12 consecutive months. Businesses with taxable supplies or expenses between SAR 187,500 and SAR 375,000 may register voluntarily, while those below SAR 187,500 are not eligible under current rules. Non-resident businesses making taxable supplies inside the Kingdom must register regardless of turnover, as no threshold applies to them.

A business that crosses the mandatory threshold must submit its VAT registration application shortly after the end of the period in which it was exceeded — current practice points to roughly 20 days. Registration is completed online through the ZATCA portal using the commercial registration and national or foreign ID. Applicants create or log in to a tax account, enter legal entity details, address, IBAN, and turnover figures for the past and projected 12 months, then confirm whether registration is mandatory or voluntary before submitting.

What registered SMEs must do

Once registered, a business receives an electronic VAT certificate showing its Tax Identification Number (TIN), valid as long as it stays registered and compliant. Registered SMEs must charge 15% VAT on taxable supplies, issue compliant tax invoices, file returns electronically, and pay any VAT due by the stated deadline. Many SMEs file quarterly, while larger taxpayers file monthly based on their classification. Returns and payments are generally due by the end of the month following the tax period.

Compliant tax invoices must show the supplier's name, address and VAT number, customer details for business transactions, a unique invoice number and date, a description of goods or services with quantities and unit prices, the VAT-exclusive amount, the 15% rate, the VAT amount, and the VAT-inclusive total. Certain supplies, including exports of goods and services out of the Kingdom, are zero-rated at 0%. Understanding these rules helps SMEs avoid penalties and keep their operations running smoothly.
