Tax treatment is where the PPF scores very high. The PPF comes under the Exempt- Exempt- Exempt category. This means that the amount invested gets tax benefits, the interest is not taxed and so is the final maturity amount. The investment gets benefits under Section 80C of the IT Act. The investment however is limited to a maximum of Rs.70,000/- per year per person. This limit of Rs.70,000/- includes the deposits made in the name of any dependent children.
