In the Moadian system every invoice line must carry a goods and service ID. It is 13 digits, identifies the item and tells the system its VAT rate or exemption. Without the right ID the invoice is rejected (error 0333; see common errors).
Two kinds of ID
- Specific ID
- Belongs to one item or service and is obtained by the taxpayer from the relevant authority.
- General ID
- For when you have no specific ID or it does not appear yet; currently allowed for issuing invoices. Check the authority's notices for when this allowance ends.
Both general and specific IDs are assigned by the Ministry of Industry, Mine and Trade.
The path, step by step
- Producer or importer of goods? Get the goods ID from the national trade window (ntsw.ir).
- Providing a service? Get the service ID from the Iran national goods and services numbering centre (portal.gs1-ir.org).
- A trader buying from an earlier link in the chain? You normally use that chain's ID and need no new specific ID.
- Check it in the ID system: after VAT rating the ID appears at stuffid.tax.gov.ir. See its exemption or taxable status and expiry date there.
- Specific ID not visible? For now use the suitable general ID for those lines.
On the invoice
- Enter the ID of each line's item or service.
- The software's VAT rate must match the ID's status on stuffid, otherwise you get a “rate does not match” error.
- If you change a line's ID after issuing, since it is core data, issue a cancellation invoice and issue the correct one anew (invoice types).
In Akam Data software
In AkamTax, AkTax.app and ERPTax you enter each item's or service's ID once in its record and it is used automatically on every invoice. The whole path is in the invoice issuing process.
