Generally, making withdrawals before the age of 60 are not allowed. You can incur penalties on your withdrawals. However, rules may vary in each plan. For example If you have purchased NPS, then, in tier I accounts, there are restrictions on withdrawal. While you can withdraw easily in tier II accounts. While in the case of PPF you can withdraw up to 50% of your fund after 7 years. Policies such as Invest 4G allows withdrawal after 5 years.
