PPF i.e. Public Provident Fund is one of the best fixed income investment tools in India. It is a tax efficient investment avenue, where one can invest up to Rs. 1.5 lakh per year. The best part of PPF is that it comes under the category of E-E-E investment tools. It means that not only it has the distinction of tax deduction of the investment amount, but the interest and the amount on maturity are also tax exempt. Financial experts, therefore, suggest their clients PPF as a must have investment option.
