The July 2019 budget included a clause about reduction in Securities Transaction Tax (STT) stating that the new STT will be only applied on the premium ( Strike price - Actual price) of the option.
This change has not been implemented yet. But many websites have said that this change was effective from July 5,2019.
My questions are :
1. When will this change be implemented.
2. Why was this change not effective immediately like many other tax reforms.
