The pay for all practical purposes is Basic Pay. All other allowances (e.g., DA, HRA, CCA, Conveyance allowance, LTA, Medical allowance, etc.) are in the nature of compensatory allowances for meeting expenses on account of the increase in the cost of living (DA) or are of the reimbursement nature (e.g., House rent, Conveyance, medical, cost of travel on leave travel, etc.). Moreover, for statutory requirements such as PF, etc., the pay is considered Basic Pay only. As such, for notice pay, only Basic pay is considered and not other allowances of compensatory/reimbursement nature.
