The EPF program is a fund, providing money upon retirement, resignation or death, based on the accumulated contributions plus interest.
In this scheme both the employer and the employee contribute 12% of annual income towards the fund. Of this 24% contribution, 8.33% is given towards a family pension plan. The remaining portion (15.67%) grows at a rate of 9.5% per annum. This return is guaranteed. Also, investments up to a maximum of Rs 70,000 per annum are not taxed!
Withdrawals from EPF is allowed under certain special circumstances like buying a house, children's wedding, etc. If you quit your job and provide a declaration that you do not intend to work for the next six months you can withdraw your EPF.
