GSTR-9 & GSTR-9C for FY 2024-25 — Filing Guide Before 31 December 2026

GST compliance does not end with monthly or quarterly return filing. Businesses registered under GST are also required to complete annual compliance through filing of GSTR-9 (Annual Return) and GSTR-9C (Reconciliation Statement) wherever applicable. As the due date for FY 2024-25 approaches, taxpayers should begin preparing well in advance to avoid last-minute issues and notices.

This article explains applicability, due dates, documents required, reconciliation procedures, common mistakes, and a practical compliance checklist.

What is GSTR-9?

GSTR-9 is an annual return that consolidates the information already reported during the financial year in:

• GSTR-1
• GSTR-3B
• Other relevant GST returns

The return contains details of:

• Outward supplies
• Inward supplies
• Input Tax Credit (ITC)
• Tax paid
• Refunds

The purpose of GSTR-9 is to provide a yearly summary of GST transactions.

What is GSTR-9C?

GSTR-9C is a reconciliation statement that compares:

• Figures reported in annual GST returns

• Books of accounts

Its objective is to identify differences and provide explanations for mismatches.
