Is it legal to pay social security on behalf of others?

Legal analysis: illegal, social insurance registration is subject to territorial management. The account opening and payment unit should be the employer, that is, the employer that establishes labor relations with the workers. If the labor contract is signed with the company, social insurance should also be paid in the name of the company. At present, many companies entrust a third party to pay social security fees by using a third-party social security account, which is not in compliance with the law. According to the relevant provisions of China's Labor Law and Social Insurance Law, employers should pay social insurance for employees after establishing labor relations.

Legal basis: Article 57 of the Social Insurance Law of People's Republic of China (PRC), the employing unit shall, within 30 days from its establishment, apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal. The social insurance agency shall, within fifteen days from the date of receiving the application, examine and issue the social insurance registration certificate. Where the social insurance registration items of the employing unit are changed or the employing unit is terminated according to law, it shall, within 30 days from the date of change or termination, go to the social insurance agency to handle the change or cancellation of social insurance registration. The market supervision and management department, the civil affairs department and the organization management organ shall promptly inform the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly inform the social insurance agency of the birth, death, household registration, migration and cancellation of the individual.
