How to get a Portuguese NIF for Non-Residents

Hi all,

Following situation:

My wife and I are European nationalities, living and working in Switzerland (Non-EU, non EEA). I read this might mean we would need a fiscal representative if we want to get a NIF.

  • What would the fiscal office really do after we get the NIF? Would we get letters / invoices from the fiscal office when using this NIF to buy an apartment in Portugal for short term rental?

  • Would the address provided during NIF-request be used for any contractual obligations going into in Portugal (i.e. buying a property, paying taxes etc.?)

My wife and I have bought an apartment elsewhere in Europe but do not live there. I could give them a bill for internet with our European based property address, and my wife could give a bank account statement stating the same property address in case of need, but would that be sufficient / needed?

Your help would be very much appreciated.
