GSt Registration for multiple state required or not ?

This discussion clarifies GST registration requirements for online course providers selling across different states. Generally, if your business operates from a single location and supplies services inter-state, you only need GST registration in your home state. Invoices for inter-state supplies should charge IGST. Separate registrations in each state are typically only necessary if you have a physical presence, like a branch or head office, in those states.
