Dear Abedeen,
There are two separate points you have raised, one is under the Payment of Wages Act and the other is the Payment of Minimum Wages Act.
Payment of Minimum Wages
1) Payment of minimum wages explains that you can't pay any workman less than that. Secondly, the basic rate can't be kept less than minimum wages, which are revised from time to time by the state government, i.e., there is no need to pay DA separately; merge it with the basic. As far as statutory deductions are concerned, deduction of EPF can be done through it, computation of bonus, gratuity can be done on the basis of minimum wages (basic + DA).
Payment of Wages
2) As far as the payment of wages is concerned, it consists of various components of the salary, namely HRA, Conveyance, and other Allowances, including basic salary. Only ESIC deduction can be done on the same, and leave encashment payment is done on the same.
The net payable is the payment received after deductions of various liabilities such as EPF, ESIC, TDS, Advances, etc., and it can only be possible after the finalization of salary and wages.
Thanks and Regards,
