Why is social security different every month?

Social security is different every month, because the wages payable by employees are different every month, and the payment wages are also different. Employees' social security contributions are paid according to the wages declared by the employer in the current month. The wages declared by the employer shall be subject to the wages payable by the employer, and the wages payable shall be lower than 60% of the average wages of employees in the overall planning area last year. If it is higher than the average monthly salary of employees in the overall planning area by 300%, the average monthly salary of employees in the overall planning area shall be 300% as the base.

Personal social security payment process is as follows:

1, individual application. The applicant holds his/her ID card, household registration book and its photocopy, residence certificate issued by the community, and two recent one-inch bareheaded color photos (non-local residents should also provide his/her residence permit and photocopy), fill out the Registration Form for Individuals Participating in the Basic Old-age Insurance for Enterprise Employees, and apply for insurance at the district and county employment agencies and talent exchange centers where the household registration is located or lived;

2. Accepted by public employment agencies. If it meets the requirements of flexible employment insurance after examination, the public employment agency or talent exchange center shall establish insurance files for the applicant;

3. Institutions that handle insurance registration. After filing, the public employment agency or talent exchange center shall apply to the endowment insurance agency for insurance procedures, and the agency shall timely register the applicant for insurance and establish a personal account. The applicant shall pay the old-age insurance premium according to the regulations, which shall be paid by the public employment agency or the talent exchange center.

To sum up, because social security payment is based on the wage level, the minimum social security payment base in a region is based on the minimum requirements published locally. If the social security paid by the company to employees is in accordance with the minimum standard, then the change of deduction base will also affect social security. Two months before and after the publication of the minimum payment standard, the social security deduction of employees may change.
