PF calculation - Over time allowance or any other allowance on which PF and ESI is not liable?

As an Employer i want to contribute PF and Esi on Rs. 3500/- and Rs. 5000/- want to pay my Employees as Over time allowance or any other allowance on which PF and ESI is not liable .. Please tell me that is it possible to do in Rajasthan . I belongs from Labour Contractor Firm.

Your PF calculation should be based upon the Basic with a ceiling limit of Rs 15,000/- and not on any specific amount.
Also the ESIC calculation will be based upon the Gross and not on any specific amount. Similarly OT also have to be provided as per the calculation laid down under the Labour Laws. Please try to understand that Rs 5,000/- for OT may be may be less or more than the actual calculated amount. If the calculation of OT is more than Rs 5000/-, it will be not only deemed as non compliance but also as exploitation!
If you pay this specific OT at every month, you will have to pay ESIC and even PF.
