What is PPF?
Public Provident Fund (PPF) is a scheme of the Central Government, framed under the PPF Act of 1968. Briefly, PPF is a Government backed, long-term small savings scheme which was initially started by the Government in order to provide retirement security to self-employed individuals and workers in the unorganized sector.
So, if you are keen on a safe corpus, earning a decent tax-free rate of return, enjoying tax benefit; then PPF is for you. The contributions (i.e. investments) made to the PPF account, will earn a tax-free interest and the maturity proceeds are exempt from income-tax. But while you invest, have a long-term investment horizon; it can help you in retirement planning.
