head under whichpre mature pf amount is taxable

i have not completed my 5 years of service and withdraw my PF amount from recognized Provident Fund.
amount is less than 50,000. I have taken deduction for contribution under 80 C 8n previous years...

Is the entire amount taxable under income from salary or only to the extent of employer and employees contribution is taxable under salary and interest on employees share is under 'other source'?

please explain...
