I didn't pay social security when I joined the company.

Insurance should be paid according to actual income. The employing unit shall pay various insurances such as pension, medical care, unemployment, work injury and maternity for employees from the date of employment. It is illegal to fail to pay insurance or pay insufficient insurance, and the unit may be required to make up or make corresponding economic compensation. Otherwise, you can report to the labor inspection brigade. It should be noted that if the unit fails to pay the fee for more than 1 year, then the employee can ask for a supplementary payment; The social security bureau that has not been insured for more than 1 year cannot repay it, and the employees can only ask the unit to pay the corresponding economic compensation. If simple labor arbitration of insurance disputes is not accepted, employees can only report to the labor inspection brigade. Article 72 The sources of social insurance funds shall be determined according to the types of insurance, and social pooling shall be gradually implemented. Employers and workers must participate in social insurance and pay social insurance premiums according to law. Article 100 If an employer fails to pay social insurance premiums without reason, the labor administrative department shall order it to pay within a time limit. If it fails to pay within the time limit, it may impose a late fee. Insurance is paid by units and individuals in proportion, with reference to individual's actual salary, according to the following proportions: Beijing's pension insurance payment ratio: 20% for units (all included in the overall fund) and 8% for individuals (all included in personal accounts); Medical insurance payment ratio: unit 10%, individual 2%+3 yuan; Unemployment insurance payment ratio: unit 1.5%, individual 0.2%; Work-related injury insurance determines its work-related injury rate according to the industry scope divided by the unit, which is between 0.5% and 2%; Maternity insurance payment ratio: 0.8% for the unit, and no payment for the individual.
