Hi sir,
Happy Diwali and a very good morning. Hope you are having a pleasant day. I belong CA intermediate may 19 batch. With due respect, the provisions for Income Tax have been changed recently but have not been updated here.
As I am daily user and a viewer, I am facing a lot of difficulties. I kindly request to change the provisions as soon as possible for the betterment of the students sir. Thank you so much
With regards,
