Is it illegal for a person to pay two copies of social security?

Legal analysis: it is not illegal, but it is useless for one person to pay two social security. At the same time, individuals can only pay one kind of national social endowment insurance, and can only go through the retirement formalities of one kind of endowment insurance. If there is repeated payment, you need to transfer or surrender when you go through retirement procedures. If the insured person has a basic old-age insurance relationship in two or more places at the same time, when handling the transfer of the basic old-age insurance relationship, the social insurance agency will negotiate with him and only keep one basic old-age insurance relationship and personal account.

Legal basis: Article 10 of the Social Insurance Law of People's Republic of China (PRC), employees shall participate in the basic old-age insurance, and the employer and employees shall jointly pay the basic old-age insurance premium. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employer and other flexible employees can participate in the basic old-age insurance, and individuals pay the basic old-age insurance premium. The measures for the endowment insurance of civil servants and staff managed by reference to the Civil Service Law shall be formulated by the State Council.
