Hi Poonam,

Clarification on some of your points.

1.Basic is generally taken as a % of CTC ( 40%, 50%) as per the policy of your company depending upon the Grades or levels. But ones basic % is fixed it can not be reduced in future. So one needs to be sure for how much % basic to be kept.
2.As per minimum Wages act for specified industries basic differs as per skills and it is diffirent from state to state.
3. Minimum HRA should be 5% of your basic, you can give more also but not less than 5%.
4. Profession Tax is calculated as per the income slabes. It aslo differs from state to state. Maximum PT deducted in Maharashtra is Rs.2500.00 per year which is fully exempt form I.Tax.
5.In the offer letter you can mention the designation, level and CTC. Also if you required to receive any specific documents you can mentioned that. Also the date of joining to be mentioned in the letter and in case if that person dosen't join necessary clause should be mentioned as regards to validity of the offer letter.

I hope some of your queries would have resolved.

Regards,
