When you send a tax return (including a VAT return) you may meet an error code. These errors come from three places: the file's documents, the electronic file's information and your own computer system. Sending returns and Moadian invoices are related; see the overall path in the invoice issuing process.
Document errors
- 504 — file not complete
- Cause: the file is not at status 45 (all requested documents complete). Fix: check the file days before the deadline and arrange with the tax office and your case officer to complete it.
- 21 — electronic signature problem
- Cause: the signing certificate has expired or been revoked. Fix: get a new one (from the intermediate certificate centres) and register it.
Information errors
- 508 — electronic file information incomplete
- Cause: the file is incomplete and sending is blocked. Fix: on the tax system (tax.gov.ir) mark the sketch of the business location and set the ISIC code that matches the economic activity.
- 50 — tax authority server update
- Usually happens in the last days before the deadline; try again a few hours later.
- 10 — heavy traffic
- Transaction volume is very high; resend a few minutes later.
Your system's errors
- 8 or 80 — send-count limit
- The number of sends from one device exceeded the limit. Get permission to raise it from the authority (usually needed by financial-service companies and licensed internet cafés).
- 103 — firewall, proxy or antivirus
- Disable these temporarily for the final send and stay online to get the tracking code.
- 500 — old platform version
- A new version is released when the fiscal year starts; download it from the authority's site and update your return-sending system.
Errors for the completing user or legal representative
- 31 — invalid username or password
- Set the keyboard to English and mind upper and lower case.
- 33 — registration permission deactivated
- Go to the tax authority to check the permission.
- 34 and 37 — return-count limit
- The number of returns allowed to be registered is used up.
- 41, 43, 402 and 404 — corrective, substitute or duplicate
- A corrective return has already been registered and more than one correction is not possible. Go to the tax authority for the assessment notice and supporting documents.
Frequently asked
- What does status 45 mean? Documents and information are complete and the file is ready for the VAT certificate.
- Status 45 but cannot send? Probably the sketch or ISIC code is missing (error 508).
- Final-send error? Security software is usually interfering (error 103).
For exact tax calculation and fewer errors use full accounting software; Akam Data accounting software and ERPTax make this easy. Invoice errors are in fixing common Moadian errors.
