Search for the rules on Saudi simplified tax invoices today and the first page of results all say the same thing: issue one when the supply is worth less than SAR 1,000.
That sentence used to be correct. It stopped being correct on 9 November 2021, when Article 53 of the VAT Implementing Regulations was amended by ZATCA board resolution (21-2-7). The text in force today — the tenth edition of the Regulations, Shawwal 1446H / April 2025 — does not define a simplified invoice by amount at all. It defines it by who is standing on the other side of the transaction.
The distinction is not academic. It decides how long you have to issue the document, and whether it passes through the Authority before your customer sees it or twenty-four hours after.
The rule as it stands: the customer decides, not the amount
Article 53(1)(a) requires you to issue a standard tax invoice in four situations:
- Taxable supplies of goods or services made to another taxable person, to a non-taxable legal person, to a sole establishment, or to any other entity established in the Kingdom under the laws in force there.
- Receipt of any consideration relating to those supplies before the supply takes place.
- Intra-GCC supplies or the export of goods.
- Supply of zero-rated services to a non-resident customer in any Member State.
Article 53(7)(a) requires you to issue a simplified tax invoice in two situations: taxable supplies made to any person other than those listed above, or receipt of consideration relating to them beforehand.
So the rule reduces to one sentence. Consumer on the other side, simplified invoice. Business or established entity, standard invoice.
Note the appearance of the sole establishment in the amended text — it was not there before. A single-owner shop or a freelancer holding a commercial registration is not a walk-in consumer for the purposes of this article, and any point-of-sale system that classifies everyone paying by card as a consumer hands them the wrong document.
Where the SAR 1,000 threshold actually lives now
The number did not disappear. It moved.
Article 53(1)(c) sets out an exception: a taxable person may issue a simplified tax invoice — under the provisions of clause 7 — for the supplies referred to in sub-paragraph (a) whose value is less than one thousand (1,000) riyals.
Read the wording carefully: may, not must. The threshold is now a permission to downgrade the document on a low-value sale to a business, not a condition that defines what a simplified invoice is. And because it is an exception to sub-paragraph (a) only, it never extends to intra-GCC supplies or to the export of goods.
Put differently: a SAR 200 sale to a consumer requires a simplified invoice because of clause 7, not because of the threshold. A SAR 200 sale to a company permits a simplified invoice without requiring one.
The difference that costs the most: the issuing deadline
This is where the expensive mistake lives, and it is almost never mentioned.
Standard invoice, Article 53(1)(b): it must be issued no later than the fifteenth day of the month following the month in which the supply took place. A comfortable window.
Simplified invoice, Article 53(7)(b): it must be issued on the date of supply or on the date consideration is received in whole or in part, whichever is earlier. No window at all.
The exception is narrow. Article 53(7)(c) allows a simplified invoice to be deferred to the fifteenth of the following month provided it also carries the customer's name and address and the date of supply in addition to the clause 8 details, and only for supplies of financial services made by banks, financial institutions or insurance companies licensed in the Kingdom, or any other supplies determined by a decision of the Authority's Governor.
If you are not a bank or an insurer, your window is zero. Every system that batches the day's sales and issues them together after the shift closes breaches this clause daily, and nobody notices.
What each one must carry
Clause 5 governs the contents of a standard invoice, clause 8 those of a simplified one:
| Field | Standard | Simplified |
|---|---|---|
| Issue date, and supply date where they differ | Required | Issue date |
| Unique sequential invoice number | Required | Required |
| Supplier name, address and VAT number | Required | Required |
| Customer name, address and VAT number | Required | Not required |
| Description and quantity of goods or services | Required | Description |
| Unit price excluding tax | Required | Not required |
| Discounts or rebates | Required | Not required |
| Tax amount payable in SAR | Required | Required, or a statement that the consideration is tax-inclusive |
| Method of calculating VAT (zero-rate, exemption, margin scheme) | Required | Not required |
The material absence in the right-hand column is the customer's VAT number. That single omission explains why a simplified invoice is a poor primary document in a business-to-business relationship: nothing in it records who bore the tax.
Phase 2: clearance or reporting
The gap widens once integration begins, under ZATCA's e-invoicing controls and technical specifications resolution:
- Tax invoices and their associated notes are subject to clearance: the Authority verifies that they meet the controls, applies its cryptographic stamp only to those that do, and notifies the issuer before they are shared with the customer.
- Simplified tax invoices and their associated notes are subject to reporting: they must be transmitted to the Authority within a period not exceeding twenty-four hours from generation.
For simplified invoices specifically, a QR code must be generated and printed, carrying five fields: seller's name, seller's VAT registration number, the timestamp of the invoice, the invoice total including VAT, and the VAT amount. Each simplified invoice must also carry a cryptographic stamp tied to a stamp identifier issued through the Authority's portal, plus a UUID and a hash embedded in the following invoice to protect the sequence against tampering.
For the full picture of phases, waves and penalties, we covered it in the ZATCA Fatoorah e-invoicing guide.
A second myth: "you cannot deduct input VAT on a simplified invoice"
This claim circulates widely and is stated far too bluntly.
Article 49(7) requires, for input tax to be deducted, that the taxable person hold evidence of it as specified in Article 48 of the GCC Agreement. It then adds: where the person does not hold those documents, they may claim the deduction when able to provide the Authority with alternative evidence — and the first item the Regulations list is a simplified tax invoice properly issued in accordance with these Regulations.
So a simplified invoice is not worthless for tax purposes. But it is conditional alternative evidence rather than the primary document, and because it carries no buyer VAT number it proves that tax was charged without proving on whom. If you are the buyer and you are a business, ask for the standard invoice rather than settling for the simplified one, and verify the supplier's VAT number before you deduct — a subject we covered in verifying a Saudi VAT number and what it means for input tax.
Where these rules actually break in software
The failure is rarely in the accountant's understanding. It is in a line of logic inside the system:
- Choosing the invoice type from the amount rather than the customer type. The commonest error, and it comes straight from the repealed wording.
- Classifying a sole establishment as a consumer. The amended text places it explicitly in the standard-invoice column.
- Batching simplified invoices and issuing them after the shift closes. A breach of clause 7(b) unless you are in one of the excepted categories.
- Counting QR field lengths in characters rather than bytes. An Arabic character is two bytes in UTF-8, so an Arabic seller name produces TLV encoding that will not scan.
The first two surface by reviewing the selection rule in the invoicing system. The third shows up in the timestamp. The fourth shows up the first time anyone scans the code.
Where to start
If you issue simplified invoices by hand, or you want to see the correct shape of the QR before committing to it, our tax invoice generator builds a print-ready simplified invoice whose QR carries the five required fields, and runs entirely inside your browser so your data never leaves your machine.
And if your system picks the invoice type from the amount, or batches simplified invoices before transmitting them, the problem is in the system's logic rather than in any one file. Send us a description of how your system chooses the invoice type and we will tell you where it departs from Article 53, with no obligation.
