Till now, bank account detail was one of the mandatory requirement for getting GST Registration. As a result, businesses requiring GST registration, were required to wait till their bank account gets opened. It was causing delay in GST registration to them.
Requirement of bank account detail has now been removed at the time of GST Registration. Now it is required after first login because normally a bank account cannot be opened before commencement of business. Bank account details can be added vide amendment of non-core field.
