Every year, when it comes to tax-planning, investors consider multiple investment products. At this time, Unit Linked Insurance Plans (ULIPs) and Equity-Linked Savings Schemes (ELSSs) are mentioned in the same breath. However, other than the fact that these two are tax-saving instruments, they are as different as chalk and cheese. While a ULIP is a mix of life insurance and investment offered by life insurance companies, ELSS is a pure investment fund. They are two different products that serve entirely different purposes. First up, it is important to understand that it is never wise to mix up insurance and investments. The basic purpose of insurance is to protect while the main purpose of investments is to generate returns. Intuitively, one would think that in order to achieve one purpose the other would need to be compromised.
