GSTR-9 annual return and GSTR-9C reconciliation
GST
·
Year-end
The GST annual return should explain how the year’s sales, tax payments and input credit agree with the accounts. TheTaxCo prepares that reconciliation, files GSTR-9 and, where required, the self-certified GSTR-9C statement after your approval, and handles follow-up queries.
This is useful work even when monthly returns have been filed on time. Audit adjustments, late supplier documents, cross-year credit notes and corrections can leave differences that monthly totals alone will not explain.
Which annual forms apply
Registered persons with aggregate turnover up to ₹2 crore in a financial year are exempt from the annual return for FY 2024–25 onwards under Notification 15/2025-Central Tax. For those within the regular annual-return requirement, GSTR-9C is also required where aggregate turnover exceeds ₹5 crore. The taxpayer category and exclusions must be checked alongside turnover. Notification 15/2025-Central Tax and CGST Rules, rule 80.
The turnover test uses the prescribed aggregate figure, rather than one GSTIN’s sales in isolation. We establish the applicability conclusion for the year and prepare the registration-level workings needed for the actual forms. GSTR-9C is a self-certified reconciliation statement; it should not be described as a separate CA-certified GST audit under the former system.
The reconciliation behind the forms
We compare the final trial balance and financial statements with GSTR-1, GSTR-3B, the annual portal summary and the relevant credit data. We separate differences into timing, classification, omitted transactions, reversals, additional liability and disclosures. Each material item records the source, amount, treatment and approval needed.
The sales review covers taxable, exempt and zero-rated supplies, amendments and tax paid. The credit review separates amounts claimed, reversed, reclaimed and carried across years. Refund and demand records are reconciled separately so that an outstanding application is not mistaken for a sanctioned refund.
Where GSTR-9C applies, we reconcile the annual-return position with the audited financial statements and explain adjustments between those reporting bases. Multi-State allocations, unbilled revenue and year-end journals need supporting schedules, not a balancing figure inserted to make the forms agree.
Missed credit must use the proper claim route
GSTR-9 does not provide a route to claim fresh input tax credit. Eligible missed credit must be taken through the appropriate GSTR-3B within the applicable legal window. For FY 2025–26 invoices or debit notes, the ordinary cut-off is 30-11-2026 or furnishing the relevant annual return, whichever occurs earlier. For FY 2026–27 documents, the corresponding date is 30-11-2027. Special statutory cases require separate review. CGST Act, section 16.
We review open credit before recommending the annual-return filing date. Extra tax identified during reconciliation also needs its proper payment route; an entry in the annual form is not itself proof of payment. The portal’s annual-return instructions explain the return and payment workflow. GST Portal GSTR-9 manual.
Records, outputs and timing
Provide the complete year’s periodic returns, final books, purchase-credit reconciliations, refund and demand records, and the prior year’s annual return. We also need subsequent-period entries affecting the year under review. If the audit is unfinished, we distinguish provisional workings from the figures that can support final approval.
You receive an applicability note, annual reconciliation, draft GSTR-9 and GSTR-9C where required, and a schedule of additional payment or unresolved treatment. Submission acknowledgements and the approved evidence pack complete the filing record. We handle historic corrections and related queries through the appropriate route, recording the periods and issues requiring further work.
The normal rule 80 deadline is 31 December following the financial year, subject to extension. That gives 31-12-2026 for FY 2025–26 and 31-12-2027 for FY 2026–27. The earlier credit window means reconciliation should start before the annual-return deadline approaches.
Questions at year-end
Our turnover is below the exemption. Should we ignore differences? Exemption from GSTR-9 does not correct errors in monthly returns or books. We reconcile those differences and handle the corrections required even where no annual return is due.
Can the return be prepared before the audit finishes? Much of the matching can start. The final pack needs the relevant settled figures and an explanation of later journals before approval.
What affects preparation time? The number of GSTINs, incomplete periods, transaction types, cross-year adjustments and the need for GSTR-9C determine the work. A file with unresolved credit and sales differences needs more reconciliation than one with completed monthly schedules.
