I tried to get a NISS the other day but they wouldn't give me one because I don't own a business or have a work contract in Portugal.
It seems I'm falling through a crack at the moment because I'm resident in Portugal but only earn foreign income (I own a UK-based business), but then I came across this scheme, which seems to cover this sort of scenario:
I don't quite understand what my contributions would need to be (even with a webpage translator)?
And I wondered if anybody had compared Seguro Social Voluntário with private health insurance?
And what happens if you stop being able to make contributions for some reason.
