Is it illegal for the company to entrust a third-party institution to pay social security companies and third-party institutions?

Legal analysis: not illegal. Because according to national laws and regulations, signing a labor contract with the company must pay social security for employees. It is an agreement signed by the company and a third-party labor service company to be entrusted by the company to pay social security. As long as it pays social security to employees, it is not illegal, just outsourcing insurance business.

China's "Provisional Regulations on the Collection and Payment of Social Insurance Fees" clearly stipulates that the social management department is responsible for the collection and payment of social insurance fees, and the employer must handle social insurance for workers according to law. If the employer has gone through the social security formalities for the employee, but the employer fails to pay the social insurance premium for the employee according to the regulations, regardless of whether the social insurance premium is unpaid or refused to be paid, the social management department can force the collection according to law.

Legal basis: Paragraph 1 of Article 16 of the Labor Law of People's Republic of China (PRC) is an agreement between laborers and employers to establish labor relations and clarify the rights and obligations of both parties.
