It’s not unusual for long-term couples, particularly married couples, to share things, such as a joint bank account. What’s mine is yours, after all. Some couples also share an email address and even a mobile phone number. But what about a NIF number?

Can a married couple share a numero de identificación fiscal as well?

According to Kathleen Lo from Bordr, a company that specialises in obtaining NIFs for prospective expats, ‘each individual needs their own NIF number. As a married couple, you can share a joint bank account, but will still need your own NIF numbers to open it.’

So, it seems the NIF is a little different to a bank account and it’s something that every individual needs. Even children need a NIF eventually, usually to enroll in school.

This means that if you’re using a lawyer as a fiscal representative, you’ll have to pay for them to obtain two fiscal numbers rather than just the one. You may also need them to open a Portuguese bank account for you as well, although you may only need one bank account, as Kathleen states.
