Register official residency and become tax liable in Mauritius

Hi,


I got my residency papers in order and now the next step.


Does anyone know how to show/prove official residency in Mauritius? It seems no any government body (civil status office for example) registers your address, is this true?


And how to become tax liable? When you open a bank account with a Mauritius bank, does the bank inform the tax authorities about your finances and thus inform the MRA that I am officially tax liable on the island?
