Reconciling Book Turnover with GST Returns

Reconciling Book Turnover explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

The profit and loss account has one revenue figure. GST has one for every registration, and includes transactions the accounts eliminate entirely. The reconciliation is not arithmetic — it is a list of twelve structural reasons the two can never be equal.

"The turnover or outward supply disclosed in the statement of profit and loss should normally tally with the turnover reported in FORM GSTR-3B and FORM GSTR-1. However, invariably there will be differences." The Handbook lists twelve reconciling items — multiple registrations, supply between GSTINs of the same PAN, deemed supplies, HSN classification, discounts, advances, exchange rates, non-GST supplies, promotion schemes, reimbursements, and AS and Ind AS adjustments.

Multi-registration: consolidating the wrong way round

"Financial Statements are prepared on a consolidated basis for an entity as a whole." GST is not. An entity holds multiple GSTINs for:

• operations in multiple States;
• multiple registrations within the same State;
• registrations mandated within the same State, i.e. SEZ / DTA locations.

"The turnover of each registration is to be consolidated and compared with the turnover disclosed in the Income Statement."

And the case where that is genuinely hard: "The collation of data… in the case of pan India service contracts may be a complex exercise, if the percentage of completion method is applied to the contract as a whole and not to the services rendered by individual units with distinct GSTINs."

The auditor's step is about process, not numbers: "understand the methods, processes and controls around preparation of data obtained for different registrations" — because a contract-level percentage-of-completion figure has to be pushed down to GSTIN level by an allocation the ERP may not perform.

The item the accounts erase

"Such supplies will not get reflected in the turnover as per financial statements." Inter-branch supplies between GSTINs of the same PAN are eliminated on consolidation and taxable under GST.

Two completeness tests, both outside the general ledger:

• "cross verifying the supplies with the e-way bills generated by the entity", plus the "sales/ stock transfer registers generated out of the ERP";
• "Perform a cross-reconciliation between the outward supplies declared in FORM GSTR-1 of the supplying branch and the inward credits reflecting in FORM GSTR-2B of the receiving branch."

The second is the stronger test because it closes the loop: a stock transfer invoiced by Maharashtra should appear as credit in Karnataka's 2B, and any that does not is either unissued or misaddressed.

Deemed supplies

"Generally, transactions between related persons without any considerations do not reflect in the Financial Statements." The two the Handbook singles out:

Supply between related or distinct persons — including "the import of services by a taxable person from a related person or from any of his other establishments outside India, when made in the course or furtherance of business, without any consideration", which "will attract GST liability under the Reverse Charge Mechanism."

The example: "ABC Inc. incorporated in the US is the holding company of B Ltd. (subsidiary) in India. Services/ recharges (IT Implementation etc.) are imported by B Ltd. from ABC Inc. without any consideration. GST should be paid by B Ltd. on reverse charge basis."

Permanent transfer of business assets where credit was availed — "even if, no consideration is received… 'Permanent transfer' means transfer without any intention of receiving the goods back." And the limit: "It does not apply to the sale of personal land/ building and other personal assets."

The audit route is the related party note: "The auditor may also consider the disclosure made under Accounting Standard 18 or Ind AS 24 – 'Related Party Disclosure' to cross check." Schedule I stock transfers →

Classification, exchange rates and non-GST supplies

HSN classification. "There can be cases where the goods can be defined under multiple Chapters… there can be goods which can have different duty structure within the same Chapter." The example: everything in Chapter 64 (footwear) at 18% IGST "except, Footwear with retail sale price not exceeding Rs.2500 per pair which is subject to 5%… if such sale price is marked or embossed on the footwear itself."

The embossing condition is the audit test — a rate applied without the marking is a short payment, and it is settled in the stock item master, not the invoice.

Exchange rates. "As per GST, the exchange rate to be adopted is the rate notified under section 14 of the Customs Act in case of goods. This will lead to difference between books and GST returns." But "as per GST Rules for export services, the rate to be adopted is as per generally accepted accounting principles (GAAP)" — so the books' own rate may be used, "provided there is no significant variation."

Two different rules for goods and services, and only the goods rule produces a permanent difference.

Non-GST supplies. Employee services to the employer; goods moving between two non-taxable territories without entering India; warehoused goods before clearance for home consumption; and high sea sales by endorsement of documents of title.

And a distinction that decides real money: "a mandatory proportionate reversal under Rule 42 and 43 is required only for Paragraph 5 (Sale of land/completed building) and Paragraph 8(a) (Supply of customs warehoused goods before home consumption) as they are deemed 'exempt supplies' for credit allocation, whereas all other items (such as employee services, high sea sales, and merchant trading) are explicitly excluded and require no ITC reversal."

Accounting policy differences

Under AS: goods invoiced but risk and rewards not transferred — revenue next year, GST this year; services on percentage of completion — GST "in the return for the month in which an advance, if any, is received" or in which an invoice or progressive billing is raised; construction contracts on percentage of completion, which GST does not follow.

Under Ind AS: a foreign functional currency with INR presentation, against the section 14 Customs rate — "This variation in translation methods results in a permanent valuation difference"; and Ind AS 115, where revenue on a warranty element is postponed while "invoices are to be raised within the timeline prescribed by the Rules and tax discharged in the subsequent month."

The instruction in both cases is the same — the adjustments must be "meticulously kept on record as part of reconciliation", because they recur every year and become the opening reconciling items of the next.

Key takeaways

• The books hold one consolidated turnover; GST holds one per registration, including SEZ/DTA units in the same State.
• Pan-India service contracts on percentage of completion must be pushed down to GSTIN level by allocation.
• Inter-GSTIN supplies are eliminated in the accounts and taxable under GST — test them against e-way bills and the supplying branch's GSTR-1 versus the receiving branch's GSTR-2B.
• Deemed supplies include free imports of service from a foreign group company (RCM) and permanent transfer of business assets on which credit was availed.
• Cross-check deemed supplies against the AS 18 / Ind AS 24 related party disclosure.
• HSN mis-classification is settled in the stock item master — e.g. footwear at 5% needs the price marked or embossed on it.
• Exchange rates: section 14 Customs rate for goods, GAAP rate for export services.
• Among Schedule III items, only para 5 (land / completed building) and para 8(a) (warehoused goods) trigger rule 42/43 reversal.
• AS and Ind AS revenue timing differences are permanent features of the reconciliation and must be documented year on year.
