A common question people ask about the NIF or Portuguese fiscal number is whether or not it can expire.

Often this question is asked by people who have lived in Portugal before, and held a NIF number when they lived in Portugal. It’s also a question that’s asked by people who are thinking of moving to Portugal later on and are wondering if they should get some of the essential admin out of the way now.

Another thing to consider is whether your address is up to date as it’s quite likely the address you had given Finanças is no longer your residential address. are able to arrange a NIF for €150 (or €140 if you use the code PORTUGALIST).
