GST Return Filing

Overview

About GST Return Filing

Once your business is registered under GST, filing returns is a continuous, recurring responsibility. A GST return is a document that records your sales, purchases, output tax collected and input tax credit claimed for a given period. Even a business with no transactions in a period must file a nil return.

Missing a deadline or filing incorrect figures can lead to late fees, interest charges and the blocking of your input tax credit. Over time, repeated non-compliance can even affect your GST registration status. GSTNumber takes this burden off your shoulders — we prepare and file your returns accurately every period, reconcile your credit, and remind you well before each due date so nothing is ever missed.
