Hi!
One of my friends a Regular GST dealer, changed to composite scheme on Nov 1 and the change was accepted.
He wants to pay taxes for Sept and Oct, but the return dashboard shows the composition screen. The screen to pay as Regular GST dealer for months before Nov is not showing.
kindly guide as to how to upload the returns for Sept and Oct as regular GST dealer.
Thanks
