Saudi tax invoices must satisfy both the VAT invoicing rules and, where applicable, ZATCA’s FATOORAH e-invoicing requirements.
The requirements affect more than the VAT rate shown on an invoice. Businesses need to use the correct invoice type, include the required fields, issue the invoice at the correct time, generate it through an electronic solution, and follow the applicable Phase Two clearance or reporting process.
The rules are also still evolving through ZATCA’s phased rollout. On July 24, 2026, ZATCA announced Wave 25 of the Integration Phase, covering taxpayers whose VAT-subject revenues exceeded SAR 187,500 during 2022, 2023, 2024, or 2025. Affected taxpayers are to integrate with the FATOORA platform by February 1, 2027.
Penalties also vary according to the violation rather than one universal fine. For example, ZATCA states that failure to issue electronic invoices begins with a SAR 5,000 fine, while certain missing e-invoice elements initially trigger a warning.
This guide explains the current Saudi tax-invoice requirements, the difference between standard and simplified invoices, invoice timing, required fields, Phase One and Phase Two rules, and common compliance mistakes.
A tax invoice documents a taxable supply and provides information used to calculate, report, and—where permitted—recover VAT.
Under Article 53 of Saudi Arabia’s VAT Implementing Regulations, a taxable supplier must issue the appropriate invoice for transactions falling within the invoicing requirements.
For e-invoicing, ZATCA generally brings resident taxable persons within the FATOORAH framework. Its detailed e-invoicing guidance specifically states that non-resident taxable persons are not required to issue Saudi electronic invoices or electronic notes for relevant supplies.
Saudi e-invoicing does not simply mean emailing a PDF.
Since December 4, 2021, taxpayers within scope must generate e-invoices and electronic notes through an electronic invoicing solution. A scanned paper invoice or an invoice manually prepared in spreadsheet or word-processing software does not qualify as a compliant e-invoice.
The exact technical requirements then depend on whether the taxpayer is still subject only to Phase One or has been brought into Phase Two, and whether the transaction requires a standard or simplified tax invoice.
Standard vs Simplified Tax Invoices in Saudi Arabia
Saudi e-invoicing commonly distinguishes between a standard tax invoice and a simplified tax invoice.
The difference is driven primarily by the type of customer and transaction, not simply whether the invoice exceeds SAR 1,000.
A standard tax invoice is generally used for B2B and B2G transactions.
ZATCA’s e-invoicing guidance describes standard invoices as invoices generally issued where a business supplies another business or government entity.
The invoice includes the information required under Article 53 of the VAT Implementing Regulations, along with additional fields required under the e-invoicing framework.
During Phase Two, standard invoices must be submitted to the FATOORA platform for clearance before being shared with the customer.
A simplified tax invoice is generally used for B2C transactions.
Importantly, there is no SAR 1,000 ceiling for ordinary B2C simplified invoices. ZATCA’s detailed guidance confirms that simplified B2C invoices can be issued even where the value exceeds SAR 1,000.
The SAR 1,000 threshold becomes relevant because a supplier may also choose to issue a simplified tax invoice for a qualifying B2B transaction where the taxable supply is below SAR 1,000.
Under Phase Two, simplified invoices are generated with the required electronic controls and must generally be reported to FATOORA within 24 hours of generation.
The correct invoice type should therefore be determined from the transaction and customer, not from invoice value alone.
The deadline depends on the invoice type and the applicable VAT date-of-supply rules.
For transactions requiring a standard tax invoice, Article 53 of the VAT Implementing Regulations generally requires the invoice to be issued no later than the 15th day of the month following the month in which the supply took place.
For example:
A taxable B2B service is supplied on March 10.
Subject to the applicable date-of-supply rules, the related tax invoice should generally be issued no later than April 15.
The deadline should not simply be calculated from when the customer eventually pays.
For ordinary supplies requiring a simplified tax invoice, the invoice generally must be issued on the earlier of:
Certain specific industries or transaction types can have separate rules, so businesses with continuous supplies, advance payments, government contracts, or other special arrangements should apply the relevant VAT date-of-supply provisions.
HAL VAT Care supports e-invoice generation, tax validation, and submission workflows for businesses implementing Saudi Phase One and Phase Two requirements.
Issuing invoices on time protects you from penalties, but ZATCA looks just as closely at what’s inside each invoice. Even one missing field can make it non-compliant.
The required fields differ between standard and simplified invoices, and Phase Two adds further electronic data requirements.
For a standard tax invoice, Article 53 of the Saudi VAT Implementing Regulations includes information such as:
Saudi tax invoices must be issued in Arabic, although another language such as English may also appear as a translation. VAT records and invoice requirements also require relevant VAT amounts to be shown in Saudi Riyals.
Simplified invoices contain a smaller minimum VAT information set, but additional FATOORAH fields—including QR and structured electronic data requirements—apply under the e-invoicing framework.
Businesses should therefore use the current ZATCA e-invoice specifications alongside the VAT regulations rather than treating one static visual invoice template as the complete compliance standard. ZATCA’s specifications page was most recently updated in January 2026.
Before diving into technical invoice requirements, it’s important to understand how ZATCA rolled out e-invoicing and what each phase actually enforces. This context will explain why certain fields, formats, and validations are mandatory today.
Saudi e-invoicing was introduced in two stages.
Phase One became mandatory on December 4, 2021.
Businesses within scope must generate and store invoices through a compliant electronic invoicing solution.
Phase One does not require every invoice to be generated as XML. ZATCA’s detailed guidance states that no specific XML or PDF/A-3 format was prescribed during this phase.
The main requirements include:
Phase Two began on January 1, 2023 and continues to roll out gradually in taxpayer waves.
The latest announced group as of August 2026 is Wave 25, with affected taxpayers required to integrate by February 1, 2027.
Phase Two introduces:
A Phase Two standard invoice is submitted to FATOORA for clearance before it is shared with the buyer.
ZATCA validates the XML and, once cleared, adds the applicable cryptographic stamp and QR information before returning the cleared invoice.
Simplified invoices are generated and issued to the customer through the taxpayer’s onboarded invoicing solution.
The solution applies the required electronic stamp and QR information, and the XML invoice must generally be reported to FATOORA within 24 hours.
This clearance-versus-reporting distinction is one of the most important Phase Two rules for businesses configuring their invoicing systems.
Even with e-invoicing in place, many compliance issues come down to small execution gaps.
Do not classify invoices solely by the SAR 1,000 threshold.
Standard invoices generally apply to B2B/B2G transactions, while simplified invoices generally apply to B2C transactions. The SAR 1,000 threshold mainly affects the option to use a simplified invoice for certain B2B supplies.
Missing supplier details, invoice dates, sequential numbers, descriptions, taxable amounts, VAT rates, or other mandatory information can create VAT and e-invoicing compliance issues.
Use the VAT Implementing Regulations together with ZATCA’s current e-invoice specifications.
Creating an invoice manually and saving it as PDF does not make it a compliant Saudi e-invoice.
The invoice must be generated through an electronic solution that meets the applicable ZATCA requirements.
Businesses already brought into Phase Two must distinguish between:
Businesses should not simply delete or alter an issued electronic invoice.
Where the value or invoice information requires correction, the VAT regulations and e-invoicing framework provide for credit notes and debit notes linked to the original invoice.
Tax invoices must contain the required information in Arabic, although another language can also be provided.
VAT payable must be shown in Saudi Riyals in accordance with the applicable invoicing requirements.
There is no single fine that applies to every invoice error.
Under ZATCA’s published VAT penalty framework:
ZATCA has also published specific e-invoicing penalties.
For example:
As of August 2026, ZATCA’s Cancellation of Fines and Exemption of Financial Penalties Initiative has been extended through December 31, 2026, subject to its eligibility rules and exclusions.
The initiative is temporary and does not eliminate the need to correct invoicing processes. Businesses should review ZATCA’s current terms before assuming a particular penalty is covered.
HAL VAT Care is HAL’s dedicated Saudi e-invoicing solution for businesses implementing ZATCA Phase One and Phase Two requirements.
HAL currently documents capabilities including:
Businesses using HAL’s wider Invoicing platform can also manage standard, recurring, and milestone invoices, invoice approvals, credit notes, payments, and invoice sharing.
Software can support the required controls and technical workflow, but the taxpayer remains responsible for correct transaction classification, VAT treatment, invoice information, and compliance with the applicable law.
Saudi tax-invoice compliance requires businesses to get several things right at the same time:
the invoice type, required data, issue timing, VAT treatment, electronic format, and the applicable ZATCA clearance or reporting process.
The most important distinction is that standard and simplified invoices do not follow identical rules. Standard invoices are generally used for B2B/B2G transactions and, under Phase Two, require clearance before sharing. Simplified invoices are generally used for B2C transactions and are reported to FATOORA within 24 hours.
Businesses should also keep monitoring their Phase Two status. ZATCA’s Wave 25 announcement confirms that the rollout is continuing into 2027.
HAL VAT Care can support the technical e-invoicing workflow through ERP integration, invoice generation, tax validation, QR processing, and ZATCA submission.
Businesses evaluating their current invoicing setup can request a HAL demo to review how their invoice flows can be integrated with FATOORA.
A standard tax invoice is generally used for B2B and B2G transactions, while a simplified tax invoice is generally used for B2C transactions.
A simplified invoice can also be used for certain B2B supplies where the taxable value is below SAR 1,000.
No.
The SAR 1,000 threshold does not create a general maximum for B2C simplified invoices. ZATCA guidance confirms that simplified B2C invoices can be issued above SAR 1,000.
The threshold mainly affects the option to issue a simplified invoice for a qualifying B2B supply.
A standard tax invoice generally must be issued no later than the 15th day of the month following the month in which the supply took place, subject to any specific VAT date-of-supply rules that apply to the transaction.
For ordinary transactions, a simplified tax invoice is generally issued at the earlier of the date of supply or the date payment is received, whether payment is received in whole or in part.
Standard tax invoices are submitted to ZATCA for clearance before being shared with the customer.
Simplified invoices are generally issued to the customer first and then reported to FATOORA within 24 hours.
Saudi e-invoicing generally applies to resident taxable persons and parties issuing invoices on their behalf.
ZATCA’s detailed guidance excludes non-resident taxable persons from the Saudi e-invoicing obligation for relevant supplies.
No.
A manually created spreadsheet, word-processing document, or scanned paper invoice is not considered a compliant electronic invoice. It must be generated using an electronic invoicing solution that meets the applicable ZATCA requirements.
Businesses should not simply delete or alter an issued e-invoice.
Where a correction is required, the VAT and e-invoicing rules provide for credit or debit notes that reference the original invoice.
