Legal analysis: there is no time limit for completing social security procedures and paying social security fees. Because it is a legal obligation for employers to handle social security procedures and pay social security fees for employees, it is against the mandatory provisions of the state for employers not to handle social security procedures and pay social security fees for employees. When the prescription system is not applicable, the employer fails to handle social security procedures and pay social security fees for employees, which not only infringes on the personal interests of employees, but also infringes on the national interests, because part of the social security fees paid go into employees' personal accounts and part of them go into the national social security fund as state property, which infringes on the national interests.
