Voluntary statutory insurance
If self-employment is your main occupation, you are not compulsorily insured in statutory health insurance (GKV), but you can be a voluntary member. If you were insured in the GKV immediately before, for example through your employer or family insurance, your membership with the health insurance fund (Krankenkasse) usually continues automatically on a voluntary basis (§ 188(4) SGB V). Without this direct link, for example after a period abroad, you need a previous insurance period to join: 24 months in the last five years or twelve months without interruption immediately before (§ 9 SGB V); you must join within three months.
