This comprehensive guide explains the four most important GST returns: GSTR-1, GSTR-3B, GSTR-9, and GSTR-9C.

Overview of GST Returns

The Four Main Returns

The main GST returns are GSTR-1, GSTR-3B, and the annual returns GSTR-9 and GSTR-9C, each with its own due date.

How They Connect

GSTR-1 captures the details of outward supplies, GSTR-3B summarizes monthly tax liabilities and payments, GSTR-9 consolidates annual data, and GSTR-9C reconciles GSTR-9 with audited financial statements.

GSTR-1: Details of Outward Supplies

Purpose

GSTR-1 is an account of details of outward supplies. It captures details of all sales made by the taxpayer during the period.

What GSTR-1 Contains

  • Details of B2B (business-to-business) supplies
  • Details of B2C (business-to-consumer) supplies
  • Details of exports
  • Details of credit notes and debit notes
  • Details of advances received

Frequency

  • Monthly (for regular taxpayers)
  • Quarterly (for QRMP scheme taxpayers)

Due Date

  • Monthly: 11th of the following month
  • Quarterly: 13th of the month following the quarter

GSTR-3B: Monthly Summary Return

Purpose

FORM GSTR-3B is where the summaries of all transactions are declared and payments are made. It is a summary return that declares the total tax liability for the period.

What GSTR-3B Contains

  • Summary of outward supplies
  • Summary of inward supplies
  • ITC claimed
  • Tax payable
  • Tax paid

Frequency

  • Monthly (for regular taxpayers)

GSTR-9: Annual Return

Purpose

GSTR-9 is the annual consolidated tax return. It contains the taxpayer's income and expenditure in detail. GSTR-9 acts as the consolidated summary of everything filed monthly or quarterly.

What GSTR-9 Contains

  • ITC claimed during the year
  • Tax paid during the year
  • Reconciliation of monthly/quarterly returns

GSTR-9C: Reconciliation Statement

What GSTR-9C Contains

  • Reconciliation of turnover declared in GSTR-9 with audited financial statements
  • Reconciliation of ITC claimed with audited financial statements
  • Audit report by a Chartered Accountant
