How to calculate the payment base of social security?

Legal analysis: the base of social security payment is generally based on my salary income in the previous year.

(1) If the wage income of employees is higher than 300% of the local average wage of employees in the previous year, 300% of the local average wage of employees in the previous year will be used as the payment base;

(two) the wage income of employees is lower than 60% of the local average wage of employees in the previous year, with 60% of the local average wage of employees in the previous year as the payment base;

(3) If the employee's salary is between 300% and 60%, it shall be declared according to the facts. When it is impossible to determine the wage income of employees, the payment base shall be determined according to the local average wage of employees in the previous year published by the local labor administrative department.

Social security will regularly check the base every year (March or July, in different places), and declare a new base according to the average monthly salary of employees in the previous year. It is necessary to prepare proof of these payroll.

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration. The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
