The Rajiv Gandhi Equity Saving Scheme (RGESS) was launched after the 2012 Budget. Investors whose annual income is less than Rs. 10 lakhs can invest in this scheme (up to Rs. 50,000) and get a deduction of 50% of the investment.
So, if you invest Rs. 50,000 (maximum amount eligible for income tax rebate is Rs. 50,000), you can claim a tax deduction of Rs. 25,000 (50% of Rs. 50,000)
