Looking for risk-free investment avenues which are ideal for tax saving too? Post office saving schemes such as PPF, NSC, Senior Citizen Savings Scheme,\u00a0Post Office Fixed Deposit and Kisan Vikas Patra are some of such options which you may consider. In fact, in these uncertain times when hardly anything is certain and getting fixed returns on investments seems to have become a thing of the past, post office saving schemes are good for generating wealth, although returns from them may not meet your expectations. \u201cPost office saving schemes carry the least risk among all investment options. As these saving schemes are issued and managed by the Government of India, the amount invested and returns generated are backed by sovereign guarantee. Their interest rates are subject to quarterly review, depending on the yields of the 10-year government bond yield,\u201d says Naveen Kukreja, CEO & Co-founder, Paisabazaar.com. There is, thus, no doubt that if you are looking for risk-free investments, then these schemes score high. In fact, they are great for tax-saving as well. However, they may not necessarily be the best choice if you are looking to build wealth over a short to medium tenure. \u201cThus, they are good options for long-term investments and for senior citizens who have additional disposable income, but do not know where to invest it. However, those who are looking to break these in emergencies and want liquid options should look at alternatives as these are tenure-locked and cannot be withdrawn before time. Even if some of them can be broken early, you will not get the interest benefit,\u201d says Adhil Shetty, CEO, Bankbazaar.com.
