The electronic invoice is one of the most significant changes to Iran's tax system in recent years. If you run a business and your sales have reached a certain threshold, you are likely required to issue this type of invoice. In this article, we explain in clear, practical language what an electronic invoice is, who is obligated to issue it, and how you can meet this requirement without confusion.

What Is an Electronic Invoice?

An electronic invoice is essentially a structured, digital sales invoice. Unlike traditional paper invoices, these must be issued and transmitted through the Taxpayers' System (Samaneh-ye Moadian) of the Iranian National Tax Administration. The main objective is to increase transaction transparency, prevent tax evasion, and centralize sales data from all businesses.

Every electronic invoice has a unique identifier and is automatically recorded in the system. This identifier enables the tax authority to easily monitor the supply and sales chain.

Electronic Invoices and the Taxpayers' System (Samaneh-ye Moadian)

The Taxpayers' System (Samaneh-ye Moadian) is the platform created by the Iranian National Tax Administration for the registration and exchange of all electronic invoices. If you want to know where to begin, read our article Taxpayers' System (Samaneh-ye Moadian) and Electronic Invoices: Where Do We Start?.

The system supports three types of invoices: Type 1 (sales to final consumers), Type 2 (sales to businesses), and Type 3 (special invoices). Each has its own specific rules and format.

Who Must Issue Electronic Invoices?

Under current regulations, all companies and legal entities are required to issue electronic invoices. In addition, sole proprietors whose annual sales or revenue exceed a specified threshold are also subject to this requirement.

Smaller businesses may become subject to the requirement in later phases. If you are just starting out or have low turnover, it is best to review your situation with a tax consultant. For small businesses, the Simple Guide to Registering in the Taxpayers' System (Samaneh-ye Moadian) is a good starting point.

Exceptions and Special Considerations

Certain businesses, such as those covered by Note 100, may be exempt from issuing electronic invoices up to a certain limit or may benefit from facilitations. However, the overall trend is toward making the requirement mandatory for all businesses. The article Note 100 for Business Owners: Who Does It Apply To and What Are the Considerations? provides further details on this topic.

Benefits of Issuing Electronic Invoices

In addition to being a legal obligation, correct issuance of electronic invoices offers many practical advantages, including reduced human error, faster settlement with customers, easier tracking of receivables, and a lower risk of tax penalties.

Businesses that implement this system correctly from the outset will face fewer difficulties when preparing their tax returns. If you make mistakes in your tax declaration, you may receive a tax assessment notice (barg-e tashkhis). The article You Received a Tax Assessment Notice: What to Do First offers useful guidance in this regard.

How to Issue an Electronic Invoice

To issue electronic invoices, you must first register in the Taxpayers' System (Samaneh-ye Moadian) and obtain a work folder. You can then issue and transmit invoices through approved accounting software or directly in the system.
