BRN, TAN and VAT in Mauritius: EBS Setup Guide
BRN, TAN and VAT Mauritius Guide for EBS Setup
Setting up a Mauritius business for MRA e-invoicing starts with three numbers: BRN, TAN and VAT. Get any of them wrong in your invoicing software and you can end up re-issuing invoices, fixing VAT returns, or paying penalties. This guide explains what each one is, where to apply, and how Codeblix uses them on every fiscal invoice.
What is a BRN in Mauritius
A BRN (Business Registration Number) is the unique ID issued by the Registrar of Companies when a business is registered. Every fiscal invoice, credit note and report Codeblix prints carries the BRN, because the MRA uses it to identify the supplier. Keep the BRN exactly as printed on the certificate (for example C24214425 for Codeblix Ltd), without spaces or dashes inside the number, and your BRN certificate PDF handy for any MRA audit.
What is a TAN in Mauritius
A TAN (Tax Account Number) is the 8-digit number the MRA gives to a registered taxpayer. Codeblix stores the TAN on the company profile and prints it on every VAT invoice you issue. The TAN identifies you as a taxpayer on every transaction report, VAT return and MRA portal submission.
What is a VAT number in Mauritius
The VAT number is the same as the TAN with a 3-digit suffix (for example 12345678/A). Codeblix uses the VAT-suffixed form on the customer invoice footer, which is the format the MRA expects. If you do VAT-exempt sales, Codeblix still prints the TAN, but does not add VAT on the line.
What you need before you start using an EBS
Before you log your first fiscal invoice in Codeblix, collect the BRN certificate, the MRA letter with the TAN, the company address exactly as registered, the director details, and the start date of your VAT registration. Codeblix pre-fills the company profile from these and validates the BRN and TAN formats before sending any invoice to the MRA.
How Codeblix uses BRN, TAN and VAT on every invoice
Every Codeblix fiscal invoice shows the BRN, TAN, VAT number, full company address and SN 95 (the MRA EBS provider register number). Each credit note references the original invoice number and reason. At month end Codeblix produces the MRA transaction report and VAT return, pre-filled from the same records.
Common mistakes to avoid
Do not invent a BRN or TAN, do not use a personal NIC instead of a business TAN, do not share one BRN across two registered companies, and do not skip the VAT suffix on customer invoices. All four create a real audit risk. Codeblix blocks the first two at save time, and validates the VAT suffix on every invoice.
FAQ
How do I find my BRN?
Your BRN is printed on the certificate issued by the Registrar of Companies. The Codeblix setup wizard asks for it on the first day you log in, and validates the format before you can save.
Is TAN the same as VAT number?
Almost. The TAN is the base 8-digit number. The VAT number is the TAN plus a 3-digit suffix (for example 12345678/A). Codeblix uses the full VAT-suffixed form on customer invoices.
Do I need all three before I can issue fiscal invoices?
Yes. Codeblix needs BRN, TAN and the VAT suffix before it can send the first invoice to the MRA. You can enter the data in the onboarding wizard and validate before going live.
Can Codeblix import BRN and TAN from myGov?
Yes. Codeblix pulls BRN, TAN, directors and registered address from the myGov company profile, then lets you confirm before saving. This avoids typos in the printed invoice.
What happens if my BRN or TAN is wrong on past invoices?
Codeblix blocks the issue at save time, so a wrong BRN or TAN should never reach the MRA. If you ever discover a typo after the fact, issue a credit note with reason and re-issue the invoice with the correct details.
