Equity Linked Saving Schemes (ELSS) are a category of Mutual Funds that get special tax treatment under Section 80C of the Income Tax Act 1961. Under this act investments up to Rs 1.5 lakh in ELSS Mutual Fund schemes are tax exempt, for which eligible taxpayers can lead to a tax saving of upto Rs 46,800. To get this benefit the investor must hold the scheme for a minimum of three years and can only sell the investment thereafter, something popularly called a lock-in period.
