Interest on Tax Amount for missed invoice?

This discussion addresses the query about paying interest on invoices missed in a previous GST return and subsequently included in the current month's GSTR-3B. It clarifies that interest is indeed applicable if the tax payment for the invoice was delayed beyond the due date. The user is seeking guidance on how to calculate this interest, especially when an invoice dated 28.06.2020 is being reported in the July 2020 return.
