Is the company that pays social security legal?

Illegal. According to the information in the query method network, the employer can entrust an agency to pay social insurance in the name of the company (that is, the social security account is still the company's account, which can be called "paying social security fees"), but it is explicitly forbidden to pay social security fees in the name of the agency account (at this time, the social security account is the agency's account). The latter's social security payment behavior has impacted the national employment registration system to a certain extent (the actual employment unit is inconsistent with the registered employment unit), which is not advocated by the government. Therefore, companies that pay social security are illegal. When handling social insurance affairs, social insurance agencies must abide by the relevant provisions of national laws and regulations on handling. When handling social insurance registration and reporting payment, the employees of the agency shall not register in the name of the employees of the agency. ".
