Retirees and self-sufficient people must prove two things:
- Private health insurance contracted with an insurer authorised in Spain, with no co-payments, no waiting periods and coverage equivalent to the public system. Minimum coverage of €30,000.
- Sufficient financial means to not be a burden on the Spanish social assistance system. The law does not set an exact minimum for EU citizens (unlike the 400% IPREM required for non-EU nationals), but in practice you need to demonstrate income or assets: pension, income, savings, property, etc.
