GSTR-9 Annual Return: A Complete Guide for FY 2025-26

The GSTR-9 annual return is one of the most comprehensive compliance requirements under the GST framework. It consolidates an entire year's worth of GST transactions — outward supplies, inward supplies, input tax credit, and tax paid — into a single return that the GST department uses to verify the accuracy of your monthly/quarterly filings.

For many businesses, GSTR-9 is also the most error-prone return — because any discrepancy between your annual return and your monthly GSTR-1 and GSTR-3B filings will be flagged by the GSTN system.

This guide covers everything you need to know about GSTR-9 for FY 2025-26.

GSTR-9 is the annual return that every regular GST-registered taxpayer must file. It is a consolidation of all the monthly/quarterly returns filed during the financial year — GSTR-1 (outward supplies) and GSTR-3B (summary return with tax payment).

Think of GSTR-9 as the annual audit of your GST compliance — it gives the department a complete picture of your GST transactions for the year and allows them to cross-check against the data already available in the GSTN system.

Mandatory for:

• All regular GST-registered taxpayers with aggregate annual turnover above ₹2 crore

Exempt from GSTR-9:

• Taxpayers with aggregate annual turnover up to ₹2 crore (filing is optional but recommended)
• Composition scheme taxpayers (they file GSTR-9A instead)
• Input Service Distributors (ISD)
• Non-resident taxable persons
• Casual taxable persons
• Taxpayers paying TDS under Section 51
• Taxpayers paying TCS under Section 52

GSTR-9C (Reconciliation Statement): Taxpayers with aggregate annual turnover above ₹5 crore must also file GSTR-9C — a reconciliation statement certified by a Chartered Accountant or Cost Accountant, comparing the figures in GSTR-9 with the audited financial statements.

The due date for GSTR-9 is 31st December following the end of the financial year.

For FY 2025-26: 31st December 2026

Late filing fee: ₹200 per day (₹100 CGST + ₹100 SGST), subject to a maximum of 0.25% of the taxpayer's turnover in the state/UT.

GSTR-9 has 6 parts and 19 tables. Here is what each part covers:

• GSTIN, legal name, trade name
• Financial year
• Aggregate turnover as declared in the annual return

Table 4 — Outward Supplies: This is where you declare all your outward supplies (sales) for the year, broken down by:

• Taxable supplies (other than zero-rated)
• Zero-rated supplies (exports and SEZ supplies)
• Nil-rated supplies
• Exempted supplies
• Non-GST supplies

The figures here should match the aggregate of your GSTR-1 filings for the year.

Table 5 — Outward Supplies on which Tax is Not Payable: Nil-rated, exempted, and non-GST outward supplies.

Table 6 — ITC Availed: Input tax credit availed during the year, broken down by:

• ITC on inputs
• ITC on input services
• ITC on capital goods
• ITC from imports
• ITC from ISD
• ITC under reverse charge

Table 7 — ITC Reversed: ITC reversed during the year — for ineligible credits, Rule 42/43 reversals, and other reasons.

Table 8 — Other ITC-Related Information: Reconciliation of ITC as per GSTR-2A/2B versus ITC actually availed. This is one of the most scrutinised tables — any excess ITC claimed over what is available in GSTR-2B will be flagged.

Table 9 — Tax Paid: Tax paid during the year through the electronic cash ledger and credit ledger, broken down by CGST, SGST, IGST, and cess.

Table 10 & 11 — Supplies and Tax Declared in Previous/Subsequent Year: Supplies relating to the current financial year that were declared in the previous year's returns, or will be declared in the next year's returns.

Transactions pertaining to FY 2024-25 that were reported in GSTR-1 or GSTR-3B of FY 2025-26 (April to September 2026 — the extended window for amendments).

• Demands and refunds
• HSN-wise summary of outward supplies
• HSN-wise summary of inward supplies
• Late fees payable and paid

The most important — and most error-prone — aspect of GSTR-9 is reconciling the figures across your three data sources:

The outward supply figures in GSTR-9 (Table 4) should match the aggregate of your GSTR-1 filings for the year. Common mismatches:

• Amendments made in subsequent months
• Credit notes and debit notes
• Advances received and adjusted
• B2C supplies reported in aggregate

The tax paid figures in GSTR-9 (Table 9) should match the aggregate of your GSTR-3B filings. Common mismatches:

• ITC availed in GSTR-3B but not reflected in GSTR-2B
• Reverse charge liability declared in GSTR-3B
• Tax paid under wrong head (IGST vs CGST/SGST)

For GSTR-9C filers, the figures in GSTR-9 must also reconcile with the audited financial statements. Common differences:

• Revenue recognition differences (GST point of supply vs accounting accrual)
• Advances and deferred revenue
• Exempt and non-GST income included in financial statements

1. Incorrect turnover declaration Turnover in GSTR-9 must match the aggregate of GSTR-1 filings. Including exempt supplies, nil-rated supplies, and non-GST supplies in the wrong tables is a common error.

2. ITC mismatch with GSTR-2B Claiming ITC in GSTR-9 that is not available in GSTR-2B will trigger a mismatch notice. Always reconcile ITC with GSTR-2B before filing.

3. Missing amendments and credit notes Amendments made in GSTR-1 after the original filing period must be correctly reflected in GSTR-9.

4. Wrong HSN codes HSN-wise summary (Table 17) must use the correct 4-digit or 8-digit HSN codes as applicable based on your turnover.

5. Not declaring ITC reversals ITC reversed during the year (for ineligible credits, Rule 42/43 proportionate reversal, etc.) must be declared in Table 7.

6. Ignoring the extended window Transactions relating to FY 2025-26 that were reported in GSTR-1/3B of April–September 2026 must be included in GSTR-9 for FY 2025-26.

For taxpayers with aggregate annual turnover above ₹5 crore, GSTR-9C is mandatory. It is a reconciliation statement that:

• Compares the figures in GSTR-9 with the audited financial statements
• Identifies and explains any differences
• Must be certified by a Chartered Accountant or Cost Accountant

Key reconciliations in GSTR-9C:

• Turnover as per financial statements vs. turnover as per GSTR-9
• ITC as per financial statements vs. ITC as per GSTR-9
• Tax payable as per GSTR-9C vs. tax paid as per GSTR-9

Step 1: Download GSTR-1 and GSTR-3B data Download the consolidated data for all months of the financial year from the GST portal.

Step 2: Reconcile with books of accounts Compare the GST portal data with your books — identify any differences and determine whether amendments are needed.

Step 3: Reconcile ITC with GSTR-2B Download the annual GSTR-2B and reconcile with ITC claimed in GSTR-3B. Identify any excess claims that need to be reversed.

Step 4: Prepare GSTR-9 data Compile the data for each table in GSTR-9 — outward supplies, ITC, tax paid, and other information.

Step 5: File on the GST portal Log in to gst.gov.in, go to Returns → Annual Return, select FY 2025-26, and file GSTR-9.

Step 6: File GSTR-9C (if applicable) If your turnover exceeds ₹5 crore, prepare and file GSTR-9C with CA certification.
