Why is the monthly social security deduction different?

Legal analysis: Because the salary payable by employees is different every month, the payment salary is also different. Employees' social security contributions are paid according to the wages declared by the employer in the current month.

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.
