GST Annual Return GSTR-9: Filing Guide, Reconciliation and Due Date

GSTR-9 is the consolidated annual return under Section 44 of the CGST Act 2017. It captures the full year's turnover, ITC availed, and tax paid, providing a complete picture of a taxpayer's GST compliance for the year. It must be reconciled with the monthly GSTR-1 and GSTR-3B filed during the year.

Who Files What

GSTR-9 Table Structure

Part I — Basic Information (Tables 1-3)

GSTIN, legal name, financial year, aggregate turnover (previous year for QRMP eligibility).

Part II — Details of Outward and Inward Supplies (Tables 4-5)

• Table 4: Taxable outward supplies (B2B, B2C, exports, zero-rated, advances)
• Table 5: Non-taxable/exempt/nil-rated/non-GST outward supplies

Part III — ITC Declared (Tables 6-8)

• Table 6: ITC availed as per GSTR-3B (inputs, input services, capital goods; by category: B2B, imports, ISD, RCM)
• Table 7: ITC reversed (Rule 37 payment default, Rule 39 ISD reversal, Rule 42/43 exempt reversal, Section 17(5) blocked)
• Table 8: Other ITC information — reconciliation of ITC in GSTR-3B with GSTR-2A/2B; difference to be declared

Part IV — Tax Paid (Tables 9-10)

Tax, interest, late fee, penalty paid via cash and ITC during the year — must reconcile with GSTR-3B totals.

Part V — Transactions for Previous FY (Table 10-11)

Amendments/credit notes/debit notes filed in April–September belonging to the previous FY.

Part VI — HSN Summary (Table 17-18)

HSN/SAC-wise summary of outward (Table 17) and inward (Table 18) supplies. Mandatory for taxpayers with turnover > Rs.5 crore to declare 6-digit HSN codes.

GSTR-9C Reconciliation Statement

Required for taxpayers with aggregate annual turnover > Rs.5 crore. Self-certified reconciliation between:

• Audited financial statements vs. GSTR-9 turnover
• ITC as per books vs. ITC claimed in GSTR-3B/GSTR-9
• Reason for any differences

No CA certification required from FY 2020-21 onwards — taxpayer's own DSC or EVC suffices. GSTR-9C is filed on the GST portal simultaneously with GSTR-9.

Common Pitfalls and Best Practices

• Ensure GSTR-1 and GSTR-3B totals match before filing GSTR-9; correct mismatches first
• Reconcile ITC in GSTR-3B with GSTR-2A/2B and explain differences in Table 8
• Identify ITC not claimed during the year — can be claimed in GSTR-9 if within time limit
• Cross-check HSN codes in invoices with GSTR-9 HSN summary
• Pay any additional tax via DRC-03 before GSTR-9 filing
• Keep GST-registered supplier invoices properly archived for 6 years (Section 36)
