GSTR-9C reconciliation statement

Who files it

• Registered taxpayers whose aggregate turnover for the year exceeded ₹5 crore.
• It is filed per GSTIN, along with or after GSTR-9 for the same year.
• Since FY 2020-21, it is self-certified by the taxpayer. Earlier it had to be certified by a chartered accountant or cost accountant. Many businesses still have their CA prepare it.

The threshold and form are set by notification and can change; confirm for the year you are filing.

Why accounts and GST returns differ

Financial statements are prepared for the whole company (one PAN), on accrual accounting rules. GST returns are prepared per GSTIN, by invoice and tax rules. Common reasons for differences:

Worked example

A company has GSTINs in Rajasthan and Gujarat. For the Rajasthan GSTIN:

Each line has to be backed by working papers. If an unexplained difference remains, for example ₹0.15 crore of sales that never reached GSTR-1, the tax on it is payable, with interest, and is shown in the statement as additional liability.

The structure of the form

• Part A: reconciliation of turnover, then taxable turnover, then tax paid by rate, then input tax credit, each between accounts and GSTR-9.
• Additional liability found through the reconciliation, with the amount payable by head.
• Reasons for every unreconciled difference must be stated.

The ITC part compares credit as per the expense and asset ledgers in the accounts with credit claimed in GSTR-9, which brings out blocked credits booked as ITC and credit missed in the books.

How to prepare

1. Get the audited (or final) financial statements and the trial balance.
2. Split revenue by GSTIN, using branch-wise ledgers or cost centres.
3. List the reconciling items above with amounts and evidence.
4. Reconcile tax by rate: the sales at each rate in the accounts with the rate-wise figures in GSTR-9.
5. Reconcile ITC ledger by ledger.
6. Pay any additional tax through DRC-03 with interest.
7. File GSTR-9C on the portal after GSTR-9, with the reasons for differences.

This is general information, not tax advice. GSTR-9C is a statement many businesses prepare with their CA.

Setting up the books so 9C is easier

• One company per GSTIN in the accounting software, or at least branch-wise cost centres and sales ledgers, so revenue can be split without estimates.
• Separate ledgers for stock transfers to other-state branches, so the GST value of transfers is a single figure.
• Separate ledgers for financial credit notes (no GST) and GST credit notes, because they reconcile differently.
• Year-end unbilled revenue and provisions passed as clearly named journal entries, so they are easy to list as reconciling items.

Set these up at the start of the year, not in November of the next year.

Common mistakes

• Not keeping branch-wise revenue in the books, so splitting accounts by GSTIN becomes guesswork.
• Forgetting stock transfers, which are the biggest reconciling item for multi-state businesses.
• Explaining differences as "timing" without showing where they reversed.
• Treating GSTR-9C as a formality. Unexplained differences are a common starting point for scrutiny.

Using Tally data with Cashflow OS

If each branch or GSTIN is a separate company in TallyPrime, Cashflow OS shows all of them in one account, with Profit & Loss, Trial Balance and GST views for each, across any date range. That makes it quicker to gather per-GSTIN figures for the reconciliation, and reports export to Excel for working papers. GSTR-9C is prepared and filed on the portal.
