I bought social security in the company for fifteen years and just resigned. Do I still need to pay?

Legal analysis: If you have paid 15 years, but haven't gone through the retirement formalities, you'd better continue to pay social security, otherwise the interruption of medical treatment will affect the reimbursement of medical expenses.

Legal basis: People's Republic of China (PRC) Social Insurance Law.

Article 86 If an employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay or make up for it within a time limit. If it fails to pay, it shall be subject to a daily fine of 0.5% from the date of default, and the relevant administrative department shall impose a fine of more than one time but less than three times the unpaid amount.

Article 87 If social insurance agencies, medical institutions, pharmaceutical trading units and other social insurance service institutions defraud social insurance fund expenditures by means of fraud or forgery of certification materials, the social insurance administrative department shall order them to return the defrauded social insurance money, and impose a fine of not less than 2 times but not more than 5 times the amount defrauded. If the service agreement is terminated and the responsible person in charge and other directly responsible personnel have the qualification to practice, their qualification to practice shall be revoked according to law.

Article 90 If a social insurance premium collection agency arbitrarily changes the base and rate of social insurance premium payment, resulting in underpayment or overpayment of social insurance premium, the relevant administrative department shall order it to recover the social insurance premium that should be paid or refund the social insurance premium that should not be paid, and the directly responsible person in charge and other directly responsible personnel shall be punished according to law.
