Can Jiaxing social security be paid back?

Hello, social insurance premiums should be paid in full and on time. If the employer does not pay, it is necessary to provide the original labor contract, employment department recruitment filing materials, original wage payment vouchers, written application materials, or effective judicial documents, labor arbitration opinions and labor supervision opinions related to the payment of old-age insurance premiums to the Municipal Social Security Bureau. After examination or on-site inspection, those who meet the payment conditions can pay the basic old-age insurance premium, and other types of insurance do not pay. You don't need to sign in person.
