What is GST Return Filing?
A GST return is a statement filed online on the GST portal containing details of:
Sales made (outward supplies)
Purchases made (inward supplies)
Tax collected on sales
Tax paid on purchases (ITC claim)
By filing returns, the government tracks tax liability, while businesses get to claim input tax credit and remain compliant.
👉 Even if a business has no sales in a period, it must still file a NIL GST return to avoid penalties.
