Shantou self-employed, pay social security.

Individual industrial and commercial households need to submit their business licenses, apply for old-age insurance at the local social security bureau (center) with their personal ID cards, apply for urban medical insurance at the medical insurance center (must be non-agricultural registered permanent residence), and apply for unemployment insurance at the unemployment insurance department. The payment base is calculated based on the local average salary in the previous year. The contribution rate of endowment insurance is 20%, medical insurance is 8%, and unemployment insurance is 1.5%. Monthly payment = average salary of last year * insurance rate. Old-age insurance requires the minimum payment period to reach 15 and the legal retirement age (male 60 years old, female 55 years old) to receive the pension.
