The monthly payment is used in the current month, and 1- 10 is the audit period of the social security agency, so as to audit and settle the accepted increase and decrease business and verify the collection data of the current month; Every month 1 1 to the last working day of the month is the time for accepting the declaration. If the payer has any personnel increase or decrease, it must go through the relevant formalities in the social security agency in time in the current month (the annual declaration does not accept personnel increase or decrease in the current month, except for new units in the current month).
