6. TIN and VAT Number Connection 

In Mauritius, while the TAN is used for general tax identification, VAT-registered entities are assigned a separate VAT Registration Number. This number is distinct and is used specifically for VAT-related transactions and reporting. 

• VAT Registration Number: 

• Assigned upon successful VAT registration. 

• Used on all VAT invoices and related documentation. 

• Format: 

• The VAT Registration Number is a unique identifier, separate from the TAN and BRN. 

For detailed information on VAT registration and obligations, refer to the MRA’s VAT section.
