I think the question is related to Maternity Benefit Payment. The ESI, EPF, P. Tax, etc., are required to be deducted from the maternity benefit, i.e., salary/wages payable for 81 days, or one month extra, whatever it may be.
If the concerned staff have taken more leave than prescribed by law and if it is without pay, then obviously statutory deductions have not been applied and are not applicable.
