Zakat, Tax and Customs Authority (ZATCA) (earlier known as GAZT), has implemented Phase I of e-invoicing in Saudi Arabia from 4th December 2021. The timeline for Phase II is set from 1st January 2023. As per e-invoicing resolution, all the e-invoicing applicable taxpayers must generate Quick Response (QR) codes on invoices to make them valid.

Also, ZATCA released a mobile application (app) to verify the authenticity of the e-invoices generated by sellers. This article explains how to download and use the VAT app for verifying the e-invoices by scanning the QR code printed on the e-invoice.

What is a QR code?

A QR code is a matrix barcode with a black and white squares pattern containing basic invoice data and is included in the printed and electronic invoices. You can scan the QR code on the e-invoice using the VAT app developed by ZATCA or a third-party QR scan app.

The QR code must be present in the human-readable format to validate the printed invoice.

How to download the VAT app for validating an invoice?

ZATCA developed the VAT app and made it publicly available. You can download the VAT app from Play Store or iOS App Store.

Play Store: https://play.google.com/store/apps/details?id=com.zatca.vat

iOS App Store: https://apps.apple.com/us/app/الضريبة-المضافة/id1328845826
