ESI

For a employee salary has been increased above 15000 in February.Till March ESI has been deducted its fine.In April ESI has not been deducted as his salary is above 15000,but in May Payroll ESI is deducted on his Salary.

Its wierd that in the month of May ESI has been deducting and also there is a split in Basic ,VDA etc.. in the RT.There are no changes in IT0008 effective from April.

Please suggest.
