I know that I will need to bring certain documentation with me to the Sanitario to sign up for National Healthcare. I believe I need my residency document, codice fiscale and identity card. I know the amount you pay is based on your annual income from the previous year. Does this mean that I need to bring a tax return dcoument to show what my earnings are from 2017 so they can make that determination? Also, I have heard about a "Stato di Famiglia" document to register family members. Am I correct to assume if you are single without other family members to insure then this document is not needed? Thanks for your feedback.
