What is GSTR-9 and who needs to file it?

GSTR-9 is the annual return under GST (Section 44 of CGST Act). Every registered taxpayer must file it, except those with aggregate turnover up to Rs 2 Crore (who are exempt under Notification 10/2022-CT). It consolidates all monthly/quarterly GSTR-1 and GSTR-3B returns filed during the financial year. The due date is 31 December of the next financial year.

What is the due date for GSTR-9 for FY 2025-26?

The due date for filing GSTR-9 for FY 2025-26 (April 2025 to March 2026) is 31 December 2026. If the government extends the deadline (as has happened in some previous years), the extended date will apply. GSTR-9C, if applicable, must also be filed by the same date.

What is the late fee for delayed GSTR-9 filing?

The late fee for GSTR-9 is Rs 200 per day of delay (Rs 100 CGST + Rs 100 SGST), subject to a maximum cap of 0.04% of the taxpayer's turnover in the state or union territory (0.02% CGST + 0.02% SGST). For example, with Rs 15 Crore turnover and 75 days delay, the late fee would be Rs 15,000 (75 x Rs 200), capped at Rs 60,000 (0.04% of Rs 15 Crore).

What is GSTR-9C and when is it required?

GSTR-9C is a reconciliation statement required for taxpayers with aggregate turnover exceeding Rs 5 Crore. From FY 2020-21 onwards, it must be self-certified by the taxpayer (no CA audit requirement). It reconciles the figures in GSTR-9 with the audited financial statements and highlights any differences in turnover, tax paid, and ITC claimed.

How do I reconcile ITC for GSTR-9?

To reconcile ITC: (1) Sum up all ITC claimed in GSTR-3B during the FY, (2) Compare with cumulative ITC available in GSTR-2B statements, (3) If GSTR-3B ITC exceeds GSTR-2B, you have excess ITC that must be reversed with 18% interest, (4) If GSTR-3B ITC is less than GSTR-2B, you may claim the unclaimed ITC before the Section 16(4) deadline (30 November of next FY). Report all ITC details in Tables 6-8 of GSTR-9.

How to Use This Calculator

GSTR-9 Reconciliation tab

Enter your turnover as per books and turnover as per GSTR-1 (sum of all outward supplies reported). Then add tax paid via GSTR-3B and tax liability as per books. The calculator highlights mismatches in both turnover and tax, shows the additional tax payable (with estimated interest), and lists specific action items for filing GSTR-9.

ITC Reconciliation tab

Enter the total ITC claimed in GSTR-3B during the FY and the ITC available per GSTR-2B. If you have already reversed some excess ITC, enter that too. The calculator computes the net excess or shortfall, calculates interest at 18% p.a. on excess ITC, and provides step-by-step reversal instructions.

Late Fee Calculator tab

Enter your annual aggregate turnover and actual/expected filing date. The calculator checks if you are exempt (turnover ≤ ₹2 Crore), computes the late fee at ₹200/day (₹100 CGST + ₹100 SGST) capped at 0.04% of turnover, and flags whether GSTR-9C is required (turnover > ₹5 Crore).

The Formula

GSTR-9 reconciliation involves matching figures across three sources: books of accounts, GSTR-1, and GSTR-3B.

Turnover Reconciliation:
Turnover Gap = Turnover (Books) − Turnover (GSTR-1)
If positive: under-reported in GSTR-1, amend or report in Table 5
If negative: over-reported in GSTR-1, adjust in Table 10/11

Tax Reconciliation:
Tax Gap = Tax Liability (Books) − Tax Paid (GSTR-3B)
If positive: additional tax payable via DRC-03 + 18% interest
If negative: overpaid, claim refund or carry forward

ITC Reconciliation:
ITC Difference = ITC Claimed (GSTR-3B) − ITC Available (GSTR-2B)
If positive: excess ITC, reverse with 18% p.a. interest
Interest = Excess ITC × 18% × (Months / 12)

Late Fee:
Late Fee = Days of Delay × ₹200/day (₹100 CGST + ₹100 SGST)
Maximum Cap = 0.04% of Turnover (0.02% CGST + 0.02% SGST)
Final Late Fee = MIN(Uncapped Fee, Cap)

Exemptions & Thresholds:
Turnover ≤ ₹2 Crore: GSTR-9 exempt
Turnover > ₹5 Crore: GSTR-9C mandatory (self-certified)

The reconciliation ensures that what was reported in monthly/quarterly returns matches the books. Any differences must be disclosed and settled before or along with GSTR-9 filing.

Example

Rajesh — Auto parts trader in Pune, ₹15 Crore turnover

Rajesh (48) runs an auto parts trading business in Pune. His FY 2025-26 figures show some discrepancies between his books and GST returns that need reconciliation before filing GSTR-9.

Turnover & Tax Reconciliation

Turnover per books₹15,00,00,000

Turnover per GSTR-1₹14,98,50,000

Turnover gap₹1,50,000 (under-reported)

Tax per books (18%)₹27,00,000

Tax paid via GSTR-3B₹26,73,000

Tax gap (underpaid)₹27,000

Rajesh must pay the additional ₹27,000 with interest (approximately ₹2,430 at 18% for 6 months) before filing GSTR-9.

Late Fee Calculation

GSTR-9 due date31 December 2026

Actual filing date16 March 2027

Delay75 days

Late fee (75 × ₹200)₹15,000

Cap (0.04% of ₹15 Cr)₹60,000

Final late fee₹15,000 (within cap)

Since the uncapped fee (₹15,000) is below the 0.04% cap (₹60,000), the full ₹15,000 applies. Rajesh's turnover exceeds ₹5 Crore, so he must also file GSTR-9C (self-certified reconciliation statement).

FAQ

Is GSTR-9 mandatory for all GST-registered taxpayers? ▼

No. GSTR-9 is exempt for taxpayers with aggregate turnover up to ₹2 Crore in the financial year (Notification 10/2022-CT, extended for subsequent FYs). Composition dealers file GSTR-4 (annual) instead of GSTR-9. Casual taxable persons, Input Service Distributors, non-resident taxable persons, and persons paying TDS/TCS under Sections 51/52 are also exempt from GSTR-9. For taxpayers above ₹2 Crore, GSTR-9 is mandatory.

What is the difference between GSTR-9 and GSTR-9C? ▼

GSTR-9 is the annual return consolidating all monthly/quarterly returns (GSTR-1 and GSTR-3B). GSTR-9C is a reconciliation statement that compares GSTR-9 figures with audited financial statements. GSTR-9C is mandatory only for taxpayers with aggregate turnover exceeding ₹5 Crore. From FY 2020-21, GSTR-9C is self-certified by the taxpayer — the earlier requirement of CA certification was removed.

What happens if my ITC in GSTR-3B exceeds GSTR-2B? ▼

If you have claimed more ITC in GSTR-3B than what is available in GSTR-2B, you have excess ITC that must be reversed. The reversal should be reported in Tables 12/13 of GSTR-9. Additionally, interest at 18% per annum under Section 50(3) is applicable on the excess ITC that was wrongly availed and utilized. The interest is calculated from the date the excess ITC was utilized until the date of reversal. Pay the interest via DRC-03 challan along with or before filing GSTR-9.

Can I claim unclaimed ITC through GSTR-9? ▼

You can claim ITC that was available in GSTR-2B but not claimed in GSTR-3B, provided you are within the time limit under Section 16(4). For FY 2025-26, the deadline to claim ITC is the earlier of 30 November 2027 or the date of filing the annual return (GSTR-9). Report the additional ITC in Table 8 of GSTR-9. Note that ITC can only be claimed if the supplier has filed their GSTR-1 and the tax has been paid to the government.

What are the common reasons for turnover mismatch in GSTR-9? ▼

Common reasons include: (1) Credit notes or debit notes not reported in GSTR-1, (2) Advances received but not adjusted in returns, (3) Exports and deemed exports reported differently, (4) HSN classification errors leading to different rate application, (5) Branch transfers or stock transfers not properly accounted, (6) Rounding differences accumulated over 12 months, (7) Amendments filed in subsequent months not reconciled. Always reconcile monthly GSTR-1 with books before preparing GSTR-9.
