GST Annual Return Filing - What You Need to Know in 2026

📌 TL;DR - GST Annual Returns Services at a Glance

GSTR-9 is the GST annual return filed by regular taxpayers with turnover above Rs 2 crore. GSTR-9C is a self-certified reconciliation statement for businesses above Rs 5 crore. Both are due on 31st December each year. Late filing attracts Rs 50 to Rs 200 per day penalty depending on turnover slab, subject to a maximum cap.

Filing the GST annual return is the final compliance checkpoint for every financial year under the GST regime. GSTR-9 consolidates all monthly or quarterly return data - GSTR-1, GSTR-2B, and GSTR-3B - into a single summary. For businesses crossing the Rs 5 crore threshold, GSTR-9C adds a reconciliation layer between books of accounts and filed returns. Getting these forms right avoids scrutiny notices, ITC reversals, and penalty exposure.

What Is GST Annual Return (GSTR-9 and GSTR-9C)?

A GST annual return is a yearly consolidated statement of all outward supplies, inward supplies, input tax credit availed, taxes paid, and refunds claimed during a financial year, filed under Section 44 of the CGST Act, 2017.

GSTR-9 captures six parts spread across 19 tables, pulling data from GSTR-1 (outward supplies), GSTR-2B (inward supplies), and GSTR-3B (summary returns). GSTR-9C is the reconciliation statement that maps annual return figures to audited financial statements, ensuring no discrepancies between filed returns and books of accounts.

From FY 2020-21 onwards, GSTR-9C is self-certified by the taxpayer, replacing the earlier requirement of CA/CMA certification. For FY 2024-25, Notification No. 16/2025-Central Tax updated the GSTR-9 format to enable IMS-based ITC auto-population and new reversal disclosures.

Key Terms for GST Annual Returns:

Aggregate Turnover: Total value of all taxable supplies, exempt supplies, exports, and inter-state supplies of persons with the same PAN, computed on an all-India basis, excluding inward supplies under reverse charge and CGST/SGST/IGST/cess.

GSTR-9: Annual return under Form GSTR-9 consolidating all periodic returns (GSTR-1, GSTR-3B) for the financial year.

GSTR-9C: Self-certified reconciliation statement under Form GSTR-9C reconciling GSTR-9 data with audited annual financial statements.

ITC Reconciliation: Process of matching input tax credit claimed in GSTR-3B with GSTR-2B data and books of accounts.

Section 44, CGST Act: Legal provision mandating annual return filing by every registered person (other than ISD, TDS/TCS deductors, casual and non-resident taxable persons).

  • Section 44, CGST Act, 2017 - Mandates annual return filing by every registered person. A registered person can file the annual return up to 3 years from the due date (proviso to Section 44).
  • Rule 80, CGST Rules, 2017 - Prescribes forms GSTR-9 and GSTR-9C, filing timelines, and turnover thresholds.
  • Section 47(2), CGST Act - Levies late fee for delay in annual return filing.

Late Fee Structure (per Section 47(2), CGST Act):

Turnover SlabLate Fee per DayMaximum Cap
Up to Rs 5 CroreRs 50/day (CGST Rs 25 + SGST Rs 25)0.04% of turnover (0.02% CGST + 0.02% SGST)

Important Clarifications:

  • CBIC Circular No. 246/03/2025-GST (30 January 2025) clarified that late fee under Section 47(2) is computed for the complete annual return (both GSTR-9 and GSTR-9C where applicable), not separately.
  • Late fee for GSTR-9C is calculated from the date of GSTR-9 filing or due date (whichever is later) until actual GSTR-9C filing date.
  • The GST portal auto-populates late fee in Table 17 of GSTR-9C (new table added from FY 2024-25).
  • General penalty under Section 125 cannot be imposed in addition to late fee under Section 47 for the same default (Madras High Court ruling, Tvl. Jainsons Castors v. AC (ST), W.P. No. 36614/2024, decided February 2025).
  • The annual return cannot be revised after filing - Section 44 and Rule 80 provide no amendment mechanism.
