Social security increased that month, can it be reduced that month?

Before the new employer increases the number of employees, it is necessary to confirm that the old employer has helped this person to go through the formalities of reducing the number of employees or stopping the insurance for flexible employees. The payer shall increase the number of employees according to the starting salary stipulated in the Labor Contract Law (the month when the labor contract is signed), and go to the labor employment management center to handle the employee employment record before increasing the number of employees. If the number of employees should be increased in the current month, it can be handled several times within one month, regardless of whether the payer has declared the social security fee for the current month. After the increase, you can declare and pay social insurance premiums according to regulations.

If the payer (individual) makes a wrong declaration or the local tax bureau, social security department, bank and other reasons, the payer (individual) may apply for a refund.
