The working is simple and fair. However to bring to your notice that taxes are always applicable as per the Act.
Hence I felt that let not provide the PT deduction of Rs. 200 in the salary structure, instead which can be factored to basic, or HRA or Other allowance.
Rest are fine.
Nagendra, I would also like to inform you that it is imperative that your Basic should be complying as per the Minimum Wages act of the local State
EX.:- Let the ctc is 18000 Monthly
HRA : 10% of x
DA : 10% of x
TA: 5% of x
PF: 12% of x
etc. add as this is
137X/100=18000 calculate this so you can get the basic and all the amounts and ESIC will be deducted after deducting the epf contribution of employee then deduct the ESIC from the gross salary of that amount then you will get the net salary.
