GSTR-9 and GSTR-9C, annual GST reconciliation.

GSTR-9 (Annual Return):

• Mandatory for every registered taxpayer under GST (except specified categories).
• Turnover threshold: turnover above INR 2 crore in the FY. Below INR 2 crore — filing is optional (made optional via Notification 47/2019 and subsequent amendments).
• Exempt from GSTR-9: Casual Taxable Person, Non-Resident Taxable Person, Input Service Distributor, Composition dealer (files GSTR-9A instead), person deducting TDS under Section 51 (files GSTR-7), person collecting TCS under Section 52 (files GSTR-8).

Due date: 31 December following the FY. For FY 2024-25, due 31 December 2025. For FY 2025-26, due 31 December 2026. Deadlines are typically extended via CBIC notification — verify current status.

Late fee: INR 200 per day (INR 100 CGST + INR 100 SGST), capped at 0.25% of turnover.

GSTR-9C (Reconciliation Statement):

• Mandatory for taxpayers with turnover above INR 5 crore in the FY.
• Reconciles GST returns (GSTR-9) with audited financial statements (books of accounts).
• Prepared and self-certified by the taxpayer (CA certification requirement was removed effective FY 2020-21).
• Includes reconciliation of turnover, taxable supplies, ITC, tax paid.
• Filed as part of or alongside GSTR-9 on GST portal.

Note: GSTR-9C was earlier required with CA certification. Finance Act 2021 removed the CA attestation requirement; now self-certified by the taxpayer. The underlying reconciliation workload remains the same.

GSTR-9 has 19 Tables. Core reconciliation areas:

• Table 4 - Supplies on which tax is payable: outward supplies declared in GSTR-1 vs reported in GSTR-3B. Mismatch here means either under- or over-reported sales.
• Table 5 - Supplies on which tax is NOT payable: nil-rated, exempt, non-GST supplies. Must match GSTR-1 and GSTR-3B.
• Table 6 - ITC availed: ITC claimed in GSTR-3B during the FY. Must match reconciled 2B/2A ledger.
• Table 7 - ITC reversed / ineligible: Section 17(5) blocks (motor vehicles, construction materials), Rule 42/43 proportional reversal, Section 16(4) time-barred ITC.
• Table 8 - Other ITC-related information: ITC as per GSTR-2A/2B vs 3B claimed. Shortfall triggers reversal with interest; excess available-not-claimed is forgone.
• Table 9 - Payment of tax: tax paid under reverse charge, CGST/SGST/IGST/CESS breakdown.
• Tables 10-14 - Amendments, demand, refund.
• Table 15 - HSN-wise summary of outward supplies: HSN code and quantity breakdown.
• Table 16 - HSN-wise summary of inward supplies: for inputs/capital goods.

GSTR-9C adds Books-of-Accounts reconciliation:

• Turnover per audited books vs turnover declared in GSTR-9.
• Taxable supplies reconciliation (Part II).
• ITC reconciliation vs books ITC ledger (Part III).
• Tax paid reconciliation (Part IV).
• Reasons for unreconciled items (Part V).

• GSTR-1 vs GSTR-3B turnover mismatch: common when invoices are entered in 3B but not pushed to 1, or vice versa. Fix: reconcile monthly; correct via amendment in subsequent 3B or GSTR-1A.
• GSTR-3B ITC vs GSTR-2B claimed: 3B ITC exceeds 2B — indicates ITC on invoices not reported by vendor. Fix: chase vendor for GSTR-1 filing OR reverse ITC with interest.
• Books turnover vs GSTR-9 turnover: credit notes, debit notes, discounts, year-end adjustments not reflected in GST returns. Fix: reconcile Books-to-GST turnover with adjustment column in GSTR-9C.
• ITC claimed but ineligible under Section 17(5): motor vehicles (personal), construction materials for own-building, food and beverage, employee insurance (certain categories), club membership. Fix: reverse via Table 7 of GSTR-9 with interest.
• ITC time-barred under Section 16(4): ITC claimable only by the earlier of (a) due date of GSTR-3B for September of next FY, or (b) date of filing of annual return. Missed ITC lost; cannot be revived.
• Reverse charge mechanism (RCM) under Section 9(3) / 9(4) not paid: specified categories (import of services, GTA services, legal services, security services, rent of residential dwelling to registered person). Fix: pay RCM in GSTR-3B with interest; claim ITC in next period.
• HSN-wise summary missing or inaccurate: Tables 15-16 require HSN-wise breakdown of supplies. Books-level HSN tracking essential year-round.
