Equity Linked Savings Schemes (ELSS) are tax-saving mutual funds that invest at least 65% in equity and come with a three-year lock-in period, offering potential tax benefits under Section 80C of the Income Tax Act, 1961. ELSS provides options for growth, dividend payout, and dividend reinvestment, allowing investors to enjoy tax-free dividends and long-term capital gains. While ELSS investments can yield high returns, they are subject to market risks and past performance is not indicative of future results.
