GST Penalty Under Section 122: Types, Amounts & How to Avoid in 2026

Understanding GST Penalties Under Section 122 of the CGST Act

GST compliance in India is not just about timely return filing — it also means staying alert to the penalties the tax department can impose for various defaults. Section 122 of the Central Goods and Services Tax (CGST) Act, 2017 is the primary provision that deals with penalties for non-compliance. For Chartered Accountants advising businesses, a thorough understanding of this section is essential to keep clients out of trouble.

This guide breaks down the penalty framework under Section 122, lists the specific amounts applicable, and offers practical steps to avoid departmental action.

What Is Section 122 of the CGST Act?

Section 122 empowers GST officers to impose monetary penalties on registered taxpayers who commit specified offences. The provision covers a wide range of defaults — from failure to issue invoices to fraudulent availment of Input Tax Credit (ITC). Penalties under this section are in addition to any tax demand or interest that may be levied.

Section 122(1): Key Offences and Penalty Amounts

Under Section 122(1), the penalty for any of the 21 listed offences is higher of ₹10,000 or 100% of the tax due. This is a steep levy that can significantly impact businesses. Key offences include:

1. 1Supplying goods/services without issuing a tax invoice — e.g., a trader collecting GST but not issuing a proper invoice.
2. 2Issuing invoices without actual supply (bogus invoices) — a common fraud seen in ITC scams.
3. 3Collecting GST but not depositing it with the government within the prescribed period.
4. 4Availing ITC without receiving goods or services — claiming credits on fake bills.
5. 5Furnishing false returns or incorrect information — including wrong HSN codes or inflated values.
6. 6Failing to register under GST despite crossing the liability threshold.
7. 7Obstructing a GST officer during audit, inspection, or search proceedings.
8. 8Transporting goods without a valid e-Way Bill where applicable.

Section 122(1A): Penalty on Non-Taxable Persons

Inserted by the Finance Act 2020, Section 122(1A) specifically targets persons who retain the benefit of fraudulent ITC transactions but are not themselves registered under GST — such as beneficial owners behind shell firms. The penalty equals the ITC availed or passed on, making it a powerful deterrent against organised tax fraud.

Section 122(2): Reduced Penalty for General Defaults

For offences not covered under Section 122(1) — such as minor procedural lapses — the penalty is ₹10,000 or 10% of the tax due, whichever is higher. Examples include:

• Failure to issue receipt vouchers for advance payments received.
• Non-maintenance of accounts and records as required under GST rules.
• Failure to display the GST registration certificate at the principal place of business.

Section 122(3): Fixed Penalty for Specific Defaults

A penalty of up to ₹25,000 applies under Section 122(3) for:

• Failure to issue a debit note or credit note as required under Section 34.
• Furnishing incorrect information in a registration application.
• Obstructing or preventing a proper officer from performing lawful duties.

Real-World Scenarios Where Section 122 Penalties Are Triggered

Scenario 1: ITC Claimed on a Cancelled Supplier's GSTIN

A manufacturing firm in Pune claimed ₹8.5 lakh ITC from a supplier whose GST registration was later cancelled retrospectively. The department issued a show-cause notice under Section 122(1) demanding 100% penalty — ₹8.5 lakh over and above the ITC reversal plus 18% interest. The CA had to file a detailed reply establishing bona fide intent and demonstrating cross-verification steps taken at the time of procurement.

Scenario 2: e-Invoice Not Generated for B2B Supplies

A software services company with ₹12 crore annual turnover failed to generate IRN (Invoice Reference Number) for three months due to an ERP integration glitch. The GST officer initiated proceedings under Section 122(1) for non-issuance of proper invoices. Penalty levied: ₹10,000 per invoice or 100% of the tax involved, whichever was higher — a six-figure liability for a clerical oversight.

Scenario 3: GSTR-3B Filed with Suppressed Outward Supplies

A retail trader under-reported outward taxable supplies by ₹4.2 lakh for a quarter. Upon scrutiny under Section 61, a show-cause notice was issued under Section 122 for furnishing false returns. The total demand — including penalty at 100% of tax and interest at 18% per annum — crossed ₹9 lakh.

Section 73 vs Section 74 vs Section 122: Key Differences

Many CA professionals confuse Section 122 with the demand provisions under Sections 73 and 74. Here is a clear comparison:

Section 122 targets specific acts of non-compliance, while Sections 73 and 74 address tax shortfalls arising from errors or deliberate evasion.

How to Respond to a Section 122 Show-Cause Notice

If your client receives an SCN under Section 122, follow this structured approach:

1. 1Read the notice carefully — identify the exact offence alleged, the period involved, and the demand amount.
2. 2Gather documentary evidence — invoices, e-Way Bills, GSTR filings, payment challans, and ledger extracts.
3. 3Quantify the maximum exposure — determine whether 100% of tax or ₹10,000 is the higher benchmark.
4. 4Draft and file a written reply within the time specified in the notice (typically 30 days).
5. 5Request a personal hearing under Section 75(4) for complex matters where oral arguments can help.
6. 6Voluntarily pay tax and interest before adjudication — this can reduce the penalty to 25% under Section 74(5).
7. 7File an appeal under Section 107 to the First Appellate Authority within 3 months of an adverse order.

How corpus Helps CA Firms Navigate GST Penalty Risk

Managing compliance for dozens of clients raises the risk of inadvertent Section 122 violations. corpus, India's GST-native cloud accounting platform, helps CA firms reduce this risk through:

• Auto e-Invoice generation with IRN validation for all eligible B2B transactions, eliminating the most common Section 122(1) trigger before it occurs.
• GSTR-1 vs GSTR-3B divergence alerts that flag output tax mismatches before the return is filed — preventing incorrect return submissions.
• ITC auto-reconciliation with GSTR-2B, ensuring clients claim only eligible credits and never inadvertently avail ITC from cancelled or risky suppliers.
• Multi-client compliance dashboard showing due dates, pending filings, and anomaly alerts across your entire firm portfolio in one screen.
• Immutable audit trail with timestamped entries that serves as ready documentary evidence when responding to departmental notices or assessments.

With corpus, your firm has the data and documentation in place before the GST officer ever asks for it.

Conclusion: Prevention Is Always Better Than Penalty

Section 122 penalties are not trivial — at 100% of tax due, they can effectively double a client's liability overnight. The best defence is proactive compliance: issue proper tax invoices, reconcile ITC every month, generate e-invoices for all applicable B2B transactions, and file accurate returns on time.

For CA firms managing multiple clients across industries, the right accounting software is not a luxury — it is a frontline compliance risk management tool. Start using corpus today and keep every client penalty-free and audit-ready.
