I live in India. If I have decided to perform investment of 50000 INR in this year in say ELSS. But I want to perform it as a lumpsum investment, instead of SIP. I want to spread the investment in 4 lump sum transactions. So I might do first purchase in April, next in July, 3rd in October and 4th in March (mainly based on the NAVs). Can I specify this, so that my tax will not be deducted itself and I dont have to claim any tax returns.
