Is interest earned in pf account taxable?

Any amount Deposited  To PPF falls under exempt category and therefore claimed as deduction U/s 80C .

at the time of withdrawal all proceeds from PPF is also exempt provided the PPF account is not closed prematurely.

Yes it is exempted.

Shaik-ji, Rahul-ji, I want to know about PF (the account in which employer puts money on monthly basis). 

I do not want related to PPF. Kindly consider it.

1) Statutory/Public Provident Fund              Interest is Fully Exempt.

2) Recognized Provident Fund                        Interest is Taxable in Excess of 9.5% p.a.

YEAH IT IS EXEMPT !
