Do I need to pay stamp duty when I purchase mutual funds on Coin?
In the 2019-20 Union Budget, stamp duty was made applicable for the purchase of mutual funds at a rate of 0.005%. The applicable stamp duty will be adjusted with the units allotted to you rather than being separately charged.
Assume you intend to invest Rs.10,000/- in a fund, then the applicable stamp duty is – Rs.10,000 * 0.005% = 0.5 (50 Paisa)
Hence your investment amount is adjusted for stamp duty and gets reduced to Rs.9,999.50/.
The number of units you get is – Rs.9,999.50 / 10 = 999.95.
