Field-level analysis of how rigid time limits under Sections 37(3) and 39(9) of the CGST Act deny genuine ITC to MSMEs for clerical errors with no revenue loss — and the case for a special rectification mechanism.
Background and Purpose of This Article
This article examines the practical hardships faced by micro and small taxpayers in India due to the absence of an effective rectification mechanism for clerical and arithmetical errors in GST returns, particularly where there is no loss of revenue to the Government. It is grounded in field-level experience with MSMEs, especially in rural and semi-urban areas, and focuses on how rigid time limits under Sections 37(3) and 39(9) of the CGST Act result in denial of genuine Input Tax Credit (ITC) and avoidable litigation.
This note is based on a detailed representation submitted to the Amicus Curiae and senior GST officials in connection with SLP (C) Diary No. 6334/2025, presently pending before the Hon'ble Supreme Court of India, in the matter concerning denial of ITC on account of clerical or arithmetical errors in GST return filings.
Ground Realities of MSME Taxpayers
Most GST taxpayers in India are MSMEs, and a large portion are micro enterprises often managed by semi-literate proprietors. These taxpayers typically run their businesses on personal loans, hand loans from relatives, working capital loans, and term loans from banks, NBFCs and other financial service providers.
Most business structures are sole proprietorships and traditional partnership firms. The persons running these businesses often lack formal training in finance and the various tax and regulatory compliances applicable to them. Due to limited working capital, they cannot afford professional expertise for handling a complex tax system, and therefore either self-file returns using online resources or depend on under-qualified petty munims. This naturally leads to inadvertent errors while filing GSTR-1, GSTR-3B and other returns.
GST filing requires a skilled person, and given the dynamic and evolving nature of GST — with frequent amendments, notifications and circulars — even tax officials sometimes interpret provisions differently, demonstrating the complexity of the legislation rather than any lapse in understanding by taxpayers. In such an environment, mistakes such as reporting excess outward supply, wrong GSTINs or excess claim of ITC are inevitable.
Common Clerical and Arithmetical Errors in GST Returns
The following are various types of clerical or arithmetical errors in GST return filings, many of which do not cause any loss of revenue to the Government but still lead to severe consequences for taxpayers.
1. Wrong Reporting of Business-to-Business Supplies
| Particulars | Details |
|---|---|
| Description of Error | Instead of reporting to one GSTIN, supply reported to another GSTIN |
| Occurrence in GSTR-1 | Table 4A, 4B, 6B & 6C |
| Occurrence in GSTR-3B | No effect — values reported in summary, not invoice-wise |
| Limitation | 30th Nov of following FY or filing of Annual Return, whichever earlier — Sec 37(3) |
| Rectification In | GSTR-1 Tables 4A, 4B, 6B & 6C |
| Loss of Revenue | No — tax properly paid in GSTR-3B |
In the initial years of GST, suppliers often reported supplies under the wrong GSTIN instead of the actual recipient, resulting in denial of ITC to the rightful recipient. Denial of ITC and raising of demands on this ground leads to double taxation on the same supply (cascading effect), contradicting the core objective of the ITC mechanism.
2. Wrong Reporting of Place of Supply
| Particulars | Details |
|---|---|
| Description of Error | Wrong selection of place of supply in case of inter-State supply |
| Occurrence in GSTR-1 | Table 4A, 4B, 6B & 6C |
| Occurrence in GSTR-3B | No effect — IGST is paid in any case of inter-State supply |
| Limitation | 30th Nov of following FY or filing of Annual Return, whichever earlier — Sec 37(3) |
| Rectification In | GSTR-1 Tables 4A, 4B, 6B & 6C |
| Loss of Revenue | No — tax properly paid in GSTR-3B |
Scenarios where such errors may occur include: B2B inter-State supply with wrong selection of POS; B2C inter-State supply with wrong reporting of POS; and B2C intra-State supply incorrectly reported as inter-State supply.
3. Wrong Reporting of Invoice Number or Date of Supply
Here, the supplier may wrongly mention the invoice number or date of supply, resulting in denial of ITC to the recipient due to incorrect invoice details, despite full tax payment.
4. Wrong Reporting of B2B Supplies as B2C
| Particulars | Details |
|---|---|
| Description of Error | Reporting B2B as B2C — no ITC could be passed on to recipient's GSTR-2B |
| Occurrence in GSTR-1 | Table 5 (B2C Large) or Table 7 (B2C Others) |
| Occurrence in GSTR-3B | No effect |
| Limitation | 30th Nov of following FY or filing of Annual Return, whichever earlier — Sec 37(3) |
| Rectification In | Table 5 (B2C Large) or Table 7 (B2C Others) |
| Loss of Revenue | No — tax properly paid in GSTR-3B |
5. Reporting of Notional Figures in GSTR-3B
| Particulars | Details |
|---|---|
| Description of Error | Reporting of notional figures in GSTR-3B without any actual supply |
| Occurrence in GSTR-1 | No effect |
| Occurrence in GSTR-3B | Table 3 and Table 4 |
| Limitation | 30th Nov of following FY or filing of Annual Return, whichever earlier — Sec 37(3) |
| Rectification In | Table 3 and Table 4 |
| Loss of Revenue | No tax liability in absence of supply |
Sales quotations or purchase orders are sometimes treated as actual invoices, leading to reporting of notional figures in GSTR-3B, with tax liability and ITC shown even though there is no actual supply.
Errors Causing Revenue Impact — Rectification Options
| Instance | GSTR-1 | GSTR-3B | Within Time u/s 37/39 | After Time Limit |
|---|---|---|---|---|
| Under Valuation of Outward Supplies | Reduced value of tax liability reported and transferred | Reduced amount of tax paid | Can be rectified through monthly returns | Correction via payment of tax by filing DRC-03 |
| Under Payment of Tax | Tax liability properly reported | Tax liability short reported and short paid | Can be rectified through monthly returns | Correction via payment of tax by filing DRC-03 |
| Excess Claim of ITC | Not Applicable | Excess utilisation of ITC | Can be reversed in Table 4(B)(2) of GSTR-3B | Correction via payment of tax by filing DRC-03 |
However, the notional-figures case discussed above is an exception and brings in lex non cogit ad impossibilia, because practical rectification becomes impossible despite the absence of revenue loss.
Errors in Place of Supply and Fiscal Federalism
As per Section 17(2) of the IGST Act, the State portion of IGST collected by the Centre is to be apportioned to the consuming State (where the supply takes place). If the place of supply is wrongly reported and no rectification is possible beyond time limits in Section 37(3), tax revenue may be allocated to an incorrect State, undermining the intent of Section 17(2) and creating fiscal imbalances.
According to the Interim Budget 2024-25, for every rupee in the Government treasury, 63 paise comes from direct and indirect taxes, and 18 paise is contributed by GST alone — making it the single largest component of indirect tax revenue. GST was designed to promote cooperative federalism through harmonisation of State and Central taxes and equitable distribution with seamless credit flow. Systemic limitations on error rectification, however, raise concerns about fairness, efficiency and the fiscal autonomy of States.
Income Tax Act: A Comparative Perspective
Under the Income Tax Act, the Government has provided multiple avenues for rectification and correction: late filing under Section 139(4), revision under Section 139(5) with no restriction on the number of revisions, filing in response to defective-return notices, and filing updated returns under Section 139(8A) on payment of nominal additional amounts.
"No similar recourse exists in GST, despite its technological interface and high compliance requirements. Sober administration is essential whenever a new taxation system is introduced till the stakeholders get used to it."
Need for a Special Rectification Mechanism Under GST
To remove these difficulties, there is an immense need to introduce a special procedure or mechanism to correct errors requiring rectification beyond the time limits in Section 37(3) and Section 39(9) of the CGST Act. The issue has been recognised at the highest judicial level in SLP (C) Diary No. 6334/2025, where the Hon'ble Supreme Court has treated it as a systemic concern rather than an isolated anomaly.
A special procedure under Section 148 of the CGST Act or via suitable amendment could:
- Permit rectification of bona fide errors beyond statutory limits.
- Allow submission of justifications with documentary proof.
- Incorporate safeguards to prevent misuse, such as one-time declarations or professional certifications.
Existing Reliefs Under GST Indicating Policy Flexibility
Based on GST Council recommendations, the administration has already provided several practical reliefs:
- Superseding of Sec 9(4) of CGST Act for a particular period and similar treatment of Sec 5(4) of IGST Act.
- Allowing ITC based on 120%, 110% and 105% of ITC in GSTR-2A as per Rule 36 (Notification 49/2019-CT).
- Insertion of Section 16(5) — extension of due date for ITC for the first four years from inception (Finance Act 2024).
- Insertion of Section 16(6) — entitlement to ITC post revocation of registration (Finance Act 2024).
- Allowing ITC not appearing in GSTR-2A based on declaration from supplier or his Chartered Accountant.
- Rationalisation of late fees for delay in filing GSTR-3B and GSTR-1 returns.
- Rationalisation of late fees for GSTR-9 and amnesty to GSTR-9 non-filers.
- Waiver of late fee for GSTR-9C filings for FY 2017-18 to 2022-23.
- One-time relief for re-activation of cancelled GSTIN.
- Insertion of Section 128A and Rule 164 — waiver of interest and penalty on tax demands for FY 2017-18, 2018-19 and 2019-20.
- Various notifications extending deadlines of different returns under GST.
These demonstrate that calibrated relaxation is both possible and consistent with the policy approach already adopted.
Conclusion
The GST framework must strike a balance between strict tax compliance and the ground realities of India's business ecosystem, especially the MSME sector that drives GDP growth and employment. A flexible rectification mechanism beyond statutory deadlines would reduce unnecessary litigation, protect honest taxpayers, preserve cooperative fiscal federalism and reinforce trust in the fairness and transparency of the GST system.
"Taxation with a human face is the need of the hour. Denial of an opportunity to rectify genuine mistakes risks turning a 'Good and Simple Tax' into a source of hardship for the very taxpayers it aims to formalise."
