GST Scrutiny Notice (Section 61): 12 Key Discrepancies, Reply Strategy & Escalation Timing

(1) The proper officer may scrutinize the return and related particulars furnished by the registered person to verify the correctness of the return and inform the registered person of the discrepancies noticed, if any, in such manner as may be prescribed and seek his explanation thereto.

(2) In case the explanation is found acceptable, the proper officer shall inform the registered person accordingly and no further action shall be taken in this regard.

(3) In case no satisfactory explanation is furnished within a period of thirty days of being so informed by the proper officer or such further period as may be permitted by him or where the registered person, after accepting the discrepancies, fails to take the rectification measures within a period of thirty days, the proper officer may initiate appropriate action including those under section 65 or section 66 or section 67, or proceed to determine the tax and other dues under section 73 or section 74.

Section 61 is an inquiry, not an adjudication. The proper officer at Section 61 stage cannot determine tax liability, cannot issue a demand notice, and cannot impose penalty. These powers vest only at the Section 73/74 stage. Practitioners must ensure that the reply to a Section 61 notice is drafted within this framework – it is a response to an inquiry, not a defence in an adjudication. The tone, content, and admissions in a Section 61 reply must be calibrated accordingly: never use language that reads as an admission of tax liability, because the reply may be used against the taxpayer if proceedings escalate to Section 73/74.

A Section 61 notice does not mean that the officer suspects fraud or evasion. The notice is generated automatically when the GSTN algorithm detects a variance above a threshold. The vast majority of such variances have perfectly legitimate explanations – timing differences in return filing, exempt supplies excluded from GSTR-3B computation, ITC reversal already made, credit notes issued, etc. Approaching a Section 61 notice with this understanding removes the anxiety and allows for a calm, structured, analytical reply rather than a defensive or nervous response.

If 30 days is insufficient to gather documents and prepare a comprehensive reply, apply in writing to the proper officer for an extension before the 30-day deadline expires. The extension request itself demonstrates good faith and is almost invariably granted for a reasonable period. Never let the 30-day deadline pass without either filing a reply or obtaining a written extension – the automatic trigger of Section 73/74 jurisdiction on non-response is a statutory consequence that neither the taxpayer nor the officer can undo after the fact.

System trigger: GSTN comparison: aggregate taxable value in GSTR-1 invoices for the period > taxable turnover declared in GSTR-3B Table 3.1

Department’s typical contention:

Taxpayer has suppressed outward taxable supply – the invoices raised (GSTR-1) are more than the tax declared (GSTR-3B), implying that tax on some invoices was not paid.

Correct legal position:

The most common and legitimate explanation is a timing difference: GSTR-1 allows amendment and addition of invoices for a subsequent period, while GSTR-3B reflects tax actually paid. An invoice raised in March but included in GSTR-1 in April (permissible amendment) will show as a GSTR-1 surplus for March but not a GSTR-3B deficit – the tax would have been paid in April’s GSTR-3B. Additionally, credit notes, B2C vs B2B reclassification, debit note adjustments, and advances received (where GSTR-3B includes advance GST but GSTR-1 invoice is not yet raised) all create legitimate variances. The discrepancy does not imply tax evasion.

Reply strategy and documents:

Prepare a month-wise reconciliation statement: take each invoice in GSTR-1 for the period, map it to the corresponding GSTR-3B tax payment (which may be in a different period), and demonstrate the net nil difference at the annual level. Attach GSTR-1 and GSTR-3B printouts for the relevant periods. If there is a genuine shortfall, acknowledge it, compute the differential tax and interest, and pay before or with the reply – this closes the matter without Section 73/74.

System trigger: GSTN comparison: ITC claimed in GSTR-3B Table 4(A)(5) > auto-populated GSTR-2A/2B for the period by more than permissible threshold

Department’s typical contention:

Taxpayer has claimed excess/ineligible ITC – the ITC claimed is not supported by corresponding supplier filings. Possible tax fraud or accommodation entry.

Correct legal position:

Post the Finance Act 2021 amendment, Section 16(2)(c) conditions ITC eligibility on GSTR-2B reflection. However, GSTR-2A/2B data is subject to filing delays by suppliers – a supplier who filed GSTR-1 late or in the following month will not appear in the recipient’s GSTR-2B for the current period. The legal position is: (a) where the supplier has since filed GSTR-1 and the ITC now appears in a later GSTR-2B – this is a timing issue, not excess ITC; (b) where the supplier has not filed GSTR-1 at all, the recipient has a claim against the supplier under Section 16(2) proviso but the ITC may need to be reversed provisionally pending supplier filing; (c) CBDT Circular No. 183/15/2022 clarified the ITC verification procedure – ITC may be available if the taxpayer demonstrates payment to supplier, possession of invoice, and receipt of goods/services.

Reply strategy and documents:

Prepare invoice-wise reconciliation of all ITC claims vs GSTR-2A/2B. For each invoice where GSTR-2A/2B mismatch exists: (a) produce the original tax invoice; (b) produce proof of payment to supplier (bank statement); (c) produce receipt of goods/services (GRN, delivery challan, logistics proof); (d) check if the invoice now appears in later GSTR-2B months – if yes, it is a timing issue, not an excess claim. Attach GSTR-2A/2B downloads for the period. If any ITC is genuinely ineligible, reverse it in GSTR-3B for the current period and pay interest – do not leave it as a contested amount.

System trigger: GSTN comparison: aggregate e-way bill value for the period (from e-way bill portal) > GSTR-3B declared taxable turnover by a significant margin

Department’s typical contention:

Taxpayer has moved goods without corresponding GST payment – e-way bills suggest physical movement of goods at values higher than the GST turnover declared, implying undeclared supplies.

Correct legal position:

E-way bills are generated for the value of goods in transit – which includes: (a) job work movements (goods sent for job work are not a supply – no GST payable under Section 143); (b) stock transfers between the same GSTIN’s godowns (branch transfers within same state – not a supply); (c) movements of exempted goods; (d) return of goods; (e) import/export movements. None of these create a GST liability even though they require e-way bills. Additionally, e-way bill value includes freight and insurance which may be embedded in the invoice value but not the taxable value. The discrepancy is almost always explained by one or more of these categories.

Reply strategy and documents:

Prepare a categorised list of all e-way bills for the period: (a) taxable outward supply (maps to GSTR-3B turnover); (b) job work outward (exclude – no supply); (c) branch transfer same GSTIN (exclude – not supply for single GSTIN); (d) return/rejection movements; (e) exempt supply e-way bills; (f) import/export movements. Total categories (b)-(f) should explain the variance. Attach e-way bill reports downloaded from the portal, categorised with brief descriptions. For job work – attach challan under Section 143.

System trigger: GSTN comparison: GSTR-9 annual return figures for turnover or ITC differ from cumulative monthly GSTR-3B figures for the same financial year

Department’s typical contention:

Taxpayer has filed inconsistent returns – the annual return (GSTR-9) discloses more turnover or more ITC than the sum of monthly returns (GSTR-3B), suggesting undisclosed monthly liabilities or unreconciled ITC.

Correct legal position:

GSTR-9 is designed to be a reconciliation return – it specifically allows disclosure of: (a) supplies declared in GSTR-1 but not in GSTR-3B (Table 10 of GSTR-9); (b) amendments to outward supplies not covered in monthly GSTR-3B; (c) ITC on inward supplies for the year not claimed in monthly returns (Table 13 of GSTR-9 – ITC reversal and reclaim). The GSTR-9 figures will legitimately differ from cumulative GSTR-3B when these reconciliation entries are made. CBDT has also clarified through multiple circulars that GSTR-9 can be used to make good shortfalls in monthly return reporting – with payment of differential tax and interest.

Reply strategy and documents:

Produce a detailed Table-wise reconciliation of GSTR-9 vs cumulative GSTR-3B: for each table of GSTR-9 that differs from GSTR-3B cumulative, explain the nature of the difference. Key tables to address: Table 4 (outward supply reconciliation), Table 6 (ITC reconciliation), Table 10/11 (supplies and ITC adjustments). Attach relevant GSTR-1 amendments, credit notes, and debit notes that explain the differences. If differential tax arises, show payment via DRC-03 challans.

System trigger: GSTN comparison: TDS deducted by e-commerce operators or government recipients (GSTR-7/8 data) implies a higher taxable supply value than declared in GSTR-3B

Department’s typical contention:

Taxpayer’s actual supplies exceed declared GSTR-3B turnover – the TDS/TCS deducted by the operator or government department implies a higher supply value, suggesting underreporting.

Correct legal position:

TDS under Section 51 applies to taxable supplies to government entities / PSUs / local authorities. TCS under Section 52 applies to supplies through e-commerce operators. The TDS/TCS amount is 2% (TDS) or 1% (TCS) of the taxable supply value – so GSTN can reverse-compute the implied supply value. The discrepancy arises when: (a) the supplier has not claimed the TDS/TCS credit in their electronic cash ledger (it sits unmatched); (b) there is a timing mismatch between the period of deduction and the period of return; (c) the TDS/TCS was deducted on gross value including exempt items. In none of these cases is there actual undeclared turnover.

Reply strategy and documents:

Download the TDS/TCS credit available in your electronic cash ledger from the GST portal. Prepare a reconciliation of TDS/TCS credits received vs the corresponding outward supply invoices – match each TDS certificate (GSTR-7A) or TCS certificate to the specific invoice and the month of GSTR-3B declaration. If TDS/TCS credit is appearing for a period but the corresponding supply was declared in a different month, show the matching supply invoice. Claim all unclaimed TDS/TCS credits in the current return to clean up the ledger.

System trigger: Officer-initiated comparison of ITC claimed in GSTR-3B vs list of ineligible ITC under Section 17(5) CGST Act – motor vehicles, food and beverages, membership clubs, etc.

Department’s typical contention:

Taxpayer has claimed ITC on items blocked under Section 17(5) of the CGST Act – goods and services on which ITC is not admissible regardless of business use.

Correct legal position:

Section 17(5) is a list of specific blocked credits – it is exhaustive, not illustrative. The most commonly invoked items are: motor vehicles (with exceptions for dealers, transportation companies, training institutes); works contract services for immovable property; food and beverages and outdoor catering; beauty treatment and health services; club memberships; travel benefits. However, the exceptions to each block are equally important – a works contract service for plant and machinery is eligible even under Section 17(5)(c). The officer’s contention must be examined carefully: has she correctly identified that the goods/services fall within Section 17(5), or has she applied the block without examining the exceptions?

Reply strategy and documents:

For each item of ITC flagged under Section 17(5): (a) identify the specific sub-clause invoked; (b) check whether the exception applies to your business (e.g., motor vehicle for a rental car company is eligible under the exception); (c) if the ITC is genuinely ineligible – reverse it in the current period’s GSTR-3B with interest and produce DRC-03 challans; (d) if the ITC is eligible under an exception – produce the relevant documents (vehicle registration, nature of business, business use evidence) and cite the specific exception in Section 17(5). Do not accept the block without examining the exceptions.

System trigger: GSTN analysis or officer review: inward supply invoices from unregistered dealers, legal services, import of services, GTA services – no corresponding RCM payment in GSTR-3B Table 3.1(d)

Department’s typical contention:

Taxpayer has received supplies on which GST was payable on reverse charge basis but has not paid RCM tax – RCM liability on services from unregistered suppliers, legal services, security services, GTA, etc. has been overlooked.

Correct legal position:

Reverse Charge Mechanism (RCM) under Section 9(3) and 9(4) of the CGST Act applies to specific categories of supply where the recipient is liable to pay GST instead of the supplier. Section 9(3) covers notified services (legal, GTA, security, import of services, etc.); Section 9(4) covers certain supplies from unregistered persons. The officer must first establish that the specific supply falls within the notified RCM categories – not all supplies from unregistered persons attract RCM under Section 9(4) as currently notified. Additionally, if RCM tax has been paid in a subsequent period (corrected by the taxpayer), this should be demonstrated.

Reply strategy and documents:

Review all inward invoices for the scrutiny period categorised by supplier type: (a) registered suppliers – no RCM issue; (b) unregistered suppliers – identify the nature of supply and check if it falls within Section 9(4) notification; (c) legal/GTA/security/import services – compute RCM liability. If RCM was genuinely not paid – pay now via DRC-03 with interest and show the challan in the reply. The ITC on RCM-paid tax is available to the same taxpayer in the same period – the net cash outflow is often nil or small. Demonstrating payment stops the matter at Section 61 level.

System trigger: System/officer check: GSTR-1 shows zero-rated supply (exports) but no LUT ARN in system records and no IGST payment in GSTR-3B for the corresponding invoices

Department’s typical contention:

Taxpayer has treated supplies as zero-rated exports without the mandatory pre-condition – either without filing LUT or without paying IGST. Such supplies should have attracted IGST at the applicable rate.

Correct legal position:

Zero-rated supply under Section 16 of the IGST Act can be made in two ways: (a) under Letter of Undertaking (LUT) – no IGST paid, ITC refund claimed; or (b) with payment of IGST – IGST refund claimed on exported goods. If neither condition is met, the supply is not zero-rated and IGST is payable. However, the common situation is a LUT that has been filed but the ARN was not correctly entered in GSTR-1, or a LUT filed late for one quarter but exports were made from the beginning of the quarter. CBDT Circular No. 37/2018 clarified the procedure for post-export LUT filing and regularisation.

Reply strategy and documents:

Retrieve the LUT ARN from the GST portal for the relevant financial year – if LUT was filed, the ARN will be available. If the LUT ARN was not entered in GSTR-1, this is an amendment required in GSTR-1 for the relevant invoices. If LUT was filed late (after exports were made), CBDT circulars permit regularisation by paying IGST with interest and then claiming refund, or by obtaining a post-facto LUT for the earlier period in consultation with the proper officer. Attach LUT filing confirmation, export documents, and shipping bills. If no LUT was filed, pay the IGST liability with interest via DRC-03.

System trigger: Officer analysis: GSTR-3B shows both taxable and exempt outward supplies but Table 4(B) of GSTR-3B (ITC reversal) does not show proportionate reversal as required by Rule 42/43 for common ITC

Department’s typical contention:

Taxpayer has claimed full ITC on inputs and input services used for both taxable and exempt supplies – Rule 42 requires proportionate reversal of ITC attributable to exempt supply. Failure to reverse is excess ITC claim.

Correct legal position:

Rule 42 of the CGST Rules requires that where goods and services are used for both taxable and exempt supplies, the ITC must be bifurcated: ITC attributable to taxable supply is allowed; ITC attributable to exempt supply must be reversed. The formula for this reversal is prescribed in Rule 42 itself – it is based on the ratio of exempt turnover to total turnover. Rule 43 applies a similar proportionate reversal for capital goods. The officer’s contention is correct in principle – but the reversal computation must use the correct formula. Many taxpayers make the reversal annually (via GSTR-9) rather than monthly – which is permissible under Rule 42(2).

Reply strategy and documents:

Prepare a detailed Rule 42 computation for each month/quarter: total ITC claimed, ITC attributable to exempt supply (using the exempt-to-total turnover ratio), and the reversal amount. If monthly reversals were not made but annual reversal was done via GSTR-9 – show the GSTR-9 entries. If the reversal was genuinely not made – compute the differential, pay via DRC-03 with interest, and produce the challan. Provide a CA certificate certifying the Rule 42 computation if the amounts are significant.

System trigger: System check: Section 16(2)(b) requires payment to supplier within 180 days; GSTN matches ITC claimed with payment data from banking/supplier return – flags where payment not evident

Department’s typical contention:

Taxpayer has claimed ITC on invoices for which payment to the supplier has not been made within 180 days of the invoice date – Rule 37 requires reversal of such ITC with interest until payment is made.

Correct legal position:

Rule 37 of the CGST Rules requires ITC reversal where the registered person has not paid the supplier within 180 days of the invoice date. Upon reversal, the ITC becomes re-claimable once payment is eventually made. The GSTN system attempts to track this through banking data integration – but the system’s payment tracking is imperfect, and many legitimate payments made through non-standard channels (cheque, RTGS to group entities, advance adjustments) may not be captured. The correct position is that payment within 180 days discharges the Rule 37 obligation regardless of the payment mode – as long as it is a legitimate commercial payment.

Reply strategy and documents:

For each invoice flagged: (a) produce proof of payment to supplier – bank statement, cheque clearance confirmation, payment confirmation from supplier; (b) if payment was made within 180 days but through a mechanism not captured by GSTN – produce the payment proof and supplier acknowledgment; (c) if payment has not been made within 180 days – compute the ITC to be reversed under Rule 37, pay interest for the period of non-payment, and produce DRC-03 challan. Note that the ITC reversed under Rule 37 is re-available once payment is made – show the subsequent reclaim in the reply.

System trigger: GSTN comparison: Invoices in GSTR-1 show IGST charged but the supply appears to be intra-state based on supplier and recipient location – or vice versa

Department’s typical contention:

Taxpayer has applied the wrong tax head – charged IGST on what should be an intra-state supply (CGST+SGST) or vice versa. This results in the wrong government receiving the tax – IGST goes to Centre while CGST/SGST is shared between Centre and State.

Correct legal position:

Place of supply determination under the IGST Act is complex – particularly for services. The correct tax head depends on the place of supply (Section 12/13 IGST Act) and the location of the supplier. Common errors: (a) classifying services to SEZ units as intra-state when they should be IGST (SEZ is outside India for GST purposes); (b) classifying inter-state services as intra-state where the service recipient is in a different state; (c) applying IGST on B2C intra-state transactions. These errors result in the wrong government receiving the tax – but the total tax paid by the taxpayer is correct. The Supreme Court’s position is that such errors must be corrected by adjustment rather than by requiring the taxpayer to pay the correct head again.

Reply strategy and documents:

Prepare a place of supply analysis for each invoice category flagged. For cases where the wrong tax head was applied but the total tax quantum is correct: (a) file GSTR-1 amendments to correct the tax head classification; (b) the excess IGST becomes available as credit and the CGST/SGST can be paid from the electronic cash ledger; (c) cite the relevant CBIC circulars on place of supply correction. Critically, argue that no additional tax is due – only an accounting adjustment is required. Attach a chart showing the correct vs incorrect tax head computation.

System trigger: Officer analysis (often in conjunction with income tax scrutiny): revenue in audited financial statements/income tax return significantly higher than GST turnover for the same period

Department’s typical contention:

Taxpayer has declared lower revenue in GST returns than in financial statements – difference implies undeclared GST taxable supply.

Correct legal position:

Revenue in financial statements includes items that are not GST taxable turnover: (a) exempt supplies (sale of land, residential apartments pre-OC, agricultural produce, health services etc.); (b) securities and financial instruments (not supply of goods/services); (c) dividends and interest income (not supply); (d) foreign exchange fluctuation gains; (e) pre-GST period revenue in the same financial year (GST was introduced July 1, 2017 – FY 2017-18 financial statements include pre-GST revenue); (f) inter-company transactions eliminated in consolidated accounts; (g) advances received treated as revenue in accounts but not taxable until invoice/delivery under GST. The financial statement-GST gap almost always has a legitimate explanation in one or more of these categories.

Reply strategy and documents:

Prepare a bridge statement reconciling financial statement revenue to GST taxable turnover: Revenue per P&L → Less: Exempt supplies → Less: Non-supply items (interest, dividend, forex) → Less: Non-GST period revenue → Add: GST-taxable items not in P&L revenue → GST Taxable Turnover per GSTR-3B. This reconciliation is the most important document for this type of discrepancy – it is also required in GSTR-9C (Annual Reconciliation Statement). Attach relevant pages from the audited accounts, GSTR-9C (if filed), and a CA certificate certifying the reconciliation.

These words, if used in a Section 61 reply, automatically shift the applicable provision from Section 73 (which applies to cases without fraud/suppression, carrying a 3-year limitation) to Section 74 (which applies to fraud/suppression/misstatement, carrying a 5-year limitation and mandatory penalty of 100% of tax). Once you have admitted suppression, the department can invoke Section 74 against you. Never use these words – even if the taxpayer genuinely made an error, characterise it as an ‘inadvertent oversight’ or ‘bona fide mistake in computation’ rather than ‘suppression’.

Do not accept the department’s computation of the alleged discrepancy at face value. Officers frequently compute discrepancies using incorrect comparison periods, wrong tax rates, or by comparing incompatible data sets. Always independently verify the alleged discrepancy before deciding whether to pay and close, or to contest. A payment made without verification implicitly confirms the department’s computation and makes it extremely difficult to contest the basis of that computation in a subsequent appeal.

The Section 61 notice asks specific questions about specific discrepancies. Answer only what is asked – do not volunteer information about other aspects of your compliance that were not raised. Submitting additional documents that reveal other potential issues (e.g., submitting the entire purchase ledger when only specific invoices are under query) risks triggering new queries. The reply should be precise, targeted, and confined to the scope of the notice.

Ignoring a Section 61 notice is the single most costly mistake a taxpayer can make. Section 61(3) makes non-response an automatic trigger for Section 73/74 proceedings. In Section 73/74 proceedings, the department can invoke best judgment assessment under Section 62 – determining tax on the basis of available information without the taxpayer’s input. A best judgment assessment under Section 62 is presumed correct and the taxpayer’s only remedy is to file a return within 30 days, which reopens the demand. This entire cascade – from ignored Section 61 notice to best judgment assessment – is avoidable by simply responding within 30 days.

The department frequently invokes Section 74 (fraud/suppression) even where the facts do not support it – because Section 74 gives them a 5-year window vs 3 years for Section 73, and mandatory penalty vs discretionary penalty. If a Section 74 SCN is issued where there is no evidence of fraud or suppression – merely a return discrepancy – challenge the very invocation of Section 74 as the threshold jurisdictional ground in your reply and in any subsequent appeal. The burden of establishing fraud or suppression is on the department – a mere discrepancy in returns is not sufficient.
