GST Return Filing – Important Rules Every Business Should Know

Introduction

GST return filing is an important compliance activity for registered businesses in India. Businesses must identify the returns applicable to them, maintain accurate records, and submit the required information within the applicable deadlines.

Important points to understand

  • GSTR-1: Reports applicable outward supplies.

  • GSTR-3B: A summary return used to report applicable tax liabilities and input tax credit.

  • Invoice reconciliation: Compare sales and purchase records to identify discrepancies.

  • Tax payment: Verify the tax liability and available eligible credits before filing.

  • Filing deadlines: Check the latest official GST calendar for applicable due dates and extensions.

Common mistakes to avoid

  1. Reporting incorrect invoice values or GSTINs.

  2. Missing credit notes or debit notes.

  3. Claiming input tax credit without verifying eligibility.

  4. Ignoring differences between books and GST returns.

  5. Waiting until the last minute to file returns.
