GST late fees and penalties sit across at least five different sections of the CGST Act and a half-dozen notifications, and the actual amount payable in any specific case depends on which provision the department invokes, the assessee's turnover bucket, and whether the default is treated as fraud or non-fraud. This article consolidates the working numbers as they stand for FY 2025-26 and gives the section-level basis for each, so you can sanity-check what is being demanded rather than relying on a memory of "the late fee was Rs. 50 per day."

Every rupee figure mentioned below is the amount payable under the CGST Act. An equal amount is payable under the respective SGST/UTGST Act, so the combined Centre-plus-State outflow is double what is shown unless explicitly noted otherwise. Late fees and turnover-based caps are notification-driven and have been revised multiple times since 2017 — the rates here reflect the position that has continued to apply through FY 2025-26.

1. Late Filing Fee for GSTR-3B and GSTR-1 (Section 47)

Section 47(1) of the CGST Act prescribes a late fee of Rs. 100 per day, capped at Rs. 5,000, for every day a return remains unfiled past its due date. That statutory amount has been reduced by notification for GSTR-1 and GSTR-3B for several years now, and the reduced amounts continue to apply.

Daily rate (per Act, post-notification):

  • Regular return with tax payable: Rs. 50 per day combined (Rs. 25 CGST + Rs. 25 SGST).
  • Nil return (no outward supplies, no tax): Rs. 20 per day combined (Rs. 10 CGST + Rs. 10 SGST).

Maximum late fee (turnover-based, combined CGST + SGST):

  • Nil return: capped at Rs. 500 per return.
  • Aggregate turnover up to Rs. 1.5 crore in the preceding financial year: capped at Rs. 2,000 per return.
  • Aggregate turnover above Rs. 1.5 crore but up to Rs. 5 crore: capped at Rs. 5,000 per return.
  • Aggregate turnover above Rs. 5 crore: capped at Rs. 10,000 per return.

The cap applies per return per Act, so the combined outflow at the highest bucket is Rs. 10,000 (Rs. 5,000 CGST + Rs. 5,000 SGST). The reduced rates currently apply to GSTR-1 and GSTR-3B; other returns (GSTR-4 for composition dealers, GSTR-5 for non-resident taxable persons, GSTR-6 for ISD, GSTR-7 for TDS, GSTR-8 for TCS) have their own separate notifications and the rates can differ. When in doubt, check the late fee block on the GST portal at the time of filing — it computes the amount based on the latest position in force.

2. Interest on Late Payment of Tax (Section 50)

Section 50 of the CGST Act governs interest on tax that has not been paid by the due date. Two distinct rates apply depending on the nature of the default.

18% per annum on tax not paid by the due date (Section 50(1)). This is the headline interest rate. It runs from the day after the due date of the return up to the date of actual payment, on the amount of tax that remained unpaid. Importantly, after Rule 88B was introduced, where the GSTR-3B is filed late but the entire tax is paid through cash ledger only on the date of filing, interest is calculated only on the net cash component for the delay period — not on the gross tax liability. ITC utilised against output liability does not attract interest under this limb so long as the credit was eligible.

18% per annum on wrongly availed and utilised input tax credit (Section 50(3)). This is a critical provision after the Finance Act 2022 amendment, which replaced the earlier text and reduced the rate from 24% to 18%. The current law levies interest only where ITC has been both wrongly availed and actually utilised. Mere availment in the credit ledger without utilisation against an output liability does not, by itself, trigger Section 50(3) interest. Where credit is reversed before utilisation, the interest exposure under this sub-section is nil. Rule 88B(3) sets out the manner of computation, including the date from which credit is treated as utilised based on the order of debits to the electronic credit ledger.

Both interest charges are simple interest, computed daily on the outstanding amount. Interest accrues automatically by operation of law and does not require a separate adjudication order before payment becomes due — though demand and quantification typically follow only when the department audits or scrutinises the return.

3. General Penalty (Section 125)

Section 125 is the residual penalty provision. It applies where a person contravenes any provision of the Act or rules for which no specific penalty is otherwise prescribed. The penalty under Section 125 may extend up to Rs. 25,000 under the CGST Act, with an equal amount under the SGST/UTGST Act, taking the maximum combined exposure to Rs. 50,000 per default.

Common situations where Section 125 gets invoked include: non-display of GSTIN at the place of business, failure to issue or maintain prescribed accounts where a specific penalty is not separately listed, and various procedural lapses that do not fit into the more specific limbs of Section 122. The "may extend to" wording leaves the proper officer with discretion — the officer can impose a lower amount where the lapse is technical or first-time.

4. Invoice and Compliance Default (Section 122(1))

Section 122(1) lists 21 specific contraventions — covering non-issuance of invoice, issuance of incorrect or false invoice, supply without invoice, collection of tax but failure to pay, ITC availed without actual receipt of supply, refund obtained fraudulently, and similar conduct. For each of these, the penalty under Section 122(1) is Rs. 10,000 or an amount equivalent to the tax involved (tax evaded, tax not deducted or short-deducted, ITC wrongly availed or distributed, refund fraudulently claimed), whichever is higher. An equal penalty is payable under the SGST/UTGST Act.

The "whichever is higher" formulation matters because for low-value defaults the floor of Rs. 10,000 controls, while for higher-value evasion the tax-equivalent component bites instead. The penalty under Section 122(1) is independent of the demand recovery proceedings under Sections 73 and 74 — though the same conduct typically does not get penalised under both routes simultaneously.

5. Fraud Cases and Non-Fraud Demands (Section 122(2), Section 74A)

Section 122(2) deals with situations where any taxable person has supplied goods or services and either has not paid the tax, or has short-paid, erroneously refunded, or wrongly availed/utilised ITC. The sub-section bifurcates the consequence based on intent:

  • Section 122(2)(a) — non-fraud: Where the default is for any reason other than fraud, wilful misstatement or suppression of facts, the penalty is Rs. 10,000 or 10% of the tax due, whichever is higher. CGST + equal SGST.
  • Section 122(2)(b) — fraud: Where the default is on account of fraud, wilful misstatement or suppression to evade tax, the penalty is Rs. 10,000 or 100% of the tax due, whichever is higher. CGST + equal SGST.

The fraud limb under 122(2)(b) is materially harsher — the penalty equals the entire tax amount, on top of the tax itself and the 18% interest. Departmental orders that classify a default as fraud carry significant downstream consequences (ITC reversal under Rule 86A, prosecution thresholds under Section 132), so the fraud characterisation is itself the most important contestation in many adjudications.

Demand provision changeover — Sections 73, 74, and 74A. For tax periods up to and including FY 2023-24, the operative demand provisions are Section 73 (non-fraud, 10% of tax or Rs. 10,000 whichever higher) and Section 74 (fraud, 100% of tax). For FY 2024-25 onwards, the Finance (No. 2) Act 2024 inserted Section 74A as a unified demand provision — Sections 73 and 74 expressly do not apply to those periods. Section 74A consolidates the time limits and procedure into a single section but retains the bifurcated penalty: 10% of tax (or Rs. 10,000 if higher) for non-fraud cases, and 100% of tax for fraud cases. Section 74A was brought into force vide Notification 17/2024-Central Tax. The article is positioned for FY 2025-26 — so for the live periods the operative section is Section 74A; Sections 73 and 74 remain relevant only for residual proceedings on older periods.

Across all three sections, the early-payment windows are the most under-used penalty levers in the regime: pre-SCN voluntary payment of tax and interest (with 15% penalty in fraud cases, no penalty in non-fraud) closes the proceedings; payment within 30 days of SCN reduces fraud-case penalty to 25% and non-fraud to nil; payment within 30 days of the adjudication order in fraud cases reduces penalty to 50%. The exact sub-section reference depends on whether the period falls under Section 73/74 or Section 74A, but the structure of the windows is preserved across the changeover.

6. E-Way Bill and Goods-in-Transit Violations (Section 129)

Section 129 governs detention, seizure and release of goods and conveyances in transit where there is a contravention of provisions relating to e-way bills, documentation accompanying the consignment, or transport. The provision was substantially rewritten by the Finance Act 2021 with effect from 1 January 2022 — both the rates and the structure changed. The current position:

Section 129(1)(a) — owner of the goods comes forward to pay: Penalty equal to 200% of the tax payable on such goods (calculated on the value of goods at the applicable GST rate). For exempt goods, the penalty is 2% of the value of goods or Rs. 25,000, whichever is less.

Section 129(1)(b) — owner does not come forward: Penalty equal to 50% of the value of the goods or 200% of the tax payable on such goods, whichever is higher. For exempt goods, 5% of the value of goods or Rs. 25,000, whichever is less.

Three nuances that get missed:

  • The penalty under Section 129(1)(a) is computed as 200% of tax — not 200% of value. On a Rs. 10 lakh consignment of 18% GST goods, the tax is Rs. 1.8 lakh and the penalty is Rs. 3.6 lakh (CGST + SGST combined). The earlier pre-2022 formulation was 100% of tax, so this is a material increase for owners who do come forward.
  • Procedure under Section 129(3): the proper officer must issue a notice specifying the penalty within 7 days of detention or seizure, and pass the order within 7 days from the date of service of that notice. If the penalty is not paid within 15 days of receipt of that order, the detained goods or conveyance can be sold or disposed of under Section 129(6) to recover the penalty. The conveyance is released separately on payment of the penalty under Section 129(3) or Rs. 1 lakh, whichever is less.
  • Confiscation under Section 130 is a separate, independent route after the Finance Act 2021 amendment — it is no longer auto-triggered by non-payment under Section 129. Section 130 is invoked where the proper officer establishes intent to evade tax, and runs on its own SCN-and-order procedure.
  • The penalty under Section 129 is in lieu of, not in addition to, the Section 122 penalty for the same default. The tax on the underlying supply (where exigible) and any interest under Section 50 are paid separately by the supplier through normal returns.

7. Annual Return Late Fee — GSTR-9 (Section 47(2))

Section 47(2) prescribes a late fee for delayed filing of the annual return under Section 44. The statutory maximum is 0.25% of state turnover under the CGST Act and an equal 0.25% under the SGST Act, taking the combined statutory cap to 0.5% of turnover. The daily rate under the Act is Rs. 100 per day. Notification 07/2023-CT dated 31 March 2023 reduced both the daily rate and the cap for smaller taxpayers from FY 2022-23 onwards, and that reduced regime continues to apply.

For FY 2022-23 onwards (Notification 07/2023-CT, combined CGST + SGST figures):

  • Aggregate turnover up to Rs. 5 crore: Rs. 50 per day, capped at 0.04% of turnover (0.02% under each Act).
  • Aggregate turnover above Rs. 5 crore but up to Rs. 20 crore: Rs. 100 per day, capped at 0.04% of turnover.
  • Aggregate turnover above Rs. 20 crore: Rs. 200 per day, capped at 0.5% of turnover (i.e., the unreduced statutory cap of 0.25% under each Act continues for this bucket).

GSTR-9 has historically been made optional for taxpayers with aggregate turnover up to Rs. 2 crore — but this exemption is granted by a fresh notification each financial year and is not a permanent feature of the Act. The most recently issued notification on this point at the time of writing is Notification 14/2024-Central Tax, which exempted persons with turnover up to Rs. 2 crore from filing the annual return for FY 2023-24. For any later FY, confirm the corresponding annual notification on the CBIC site before treating the exemption as available; do not assume the exemption rolls over automatically.

GSTR-9C nuance for taxpayers above Rs. 5 crore. Where GSTR-9C is required (turnover exceeding Rs. 5 crore), Circular 246/03/2025-GST dated 30 January 2025 has clarified that the late fee under Section 47(2) continues to run until the complete annual return — i.e., both GSTR-9 and GSTR-9C — is furnished. Filing GSTR-9 alone without the reconciliation statement does not stop the late fee clock. For larger taxpayers, this materially changes the late-fee exposure and is a frequent source of late-fee build-up that gets noticed only at audit.

Worked Examples

Example 1 — GSTR-3B filed 30 days late, turnover Rs. 4 crore, Rs. 60,000 tax payable through cash:

  • Late fee: 30 days x Rs. 50 = Rs. 1,500 combined (within Rs. 5,000 turnover cap, so full daily rate applies).
  • Interest under Section 50(1): Rs. 60,000 x 18% x 30/365 = Rs. 888 (rounded).
  • No Section 125 penalty because Section 47 specifically deals with late filing — no residuary penalty piles on top.

Example 2 — GSTR-1 nil return filed 60 days late, turnover Rs. 80 lakh:

  • Late fee: 60 days x Rs. 20 = Rs. 1,200, but capped at Rs. 500 per return for nil filers.
  • No interest, no other penalty — nothing else triggers because there is no tax liability.

Example 3 — Goods worth Rs. 8 lakh of 18% GST goods detained for missing e-way bill, owner comes forward:

  • Tax on goods: Rs. 8,00,000 x 18% = Rs. 1,44,000.
  • Section 129(1)(a) penalty: 200% of Rs. 1,44,000 = Rs. 2,88,000 (CGST + SGST combined).
  • Amount to release goods: Rs. 2,88,000 — the penalty alone. The tax on the underlying supply is paid separately by the supplier through normal GSTR-3B; under the post-Finance-Act-2021 structure of Section 129, release of goods requires payment of penalty only, not tax-plus-penalty as under the pre-2022 text.

Example 4 — ITC of Rs. 5 lakh wrongly availed and utilised against output, picked up in scrutiny six months later:

  • Tax to be reversed: Rs. 5,00,000.
  • Interest under Section 50(3) at 18% for 180 days: Rs. 5,00,000 x 18% x 180/365 = Rs. 44,384 approx.
  • Penalty: for FY 2024-25 onwards under Section 74A, the non-fraud limb attracts 10% or Rs. 10,000 whichever higher = Rs. 50,000, while the fraud limb is 100% = Rs. 5,00,000. For periods up to FY 2023-24, the parallel comes from Section 73 (10%) or Section 74 (100%). The fraud-versus-non-fraud characterisation is everything here.

How to Avoid Penalties — Practical Approach

The compliance load that actually drives penalty exposure is narrower than people assume. A handful of disciplined practices eliminate most of it:

  • File on time even if you cannot pay. Late fees compound daily; interest at 18% is far smaller per day than late fee at Rs. 50 per day for low-tax filers. Filing the return on time and paying tax late carries only the interest, not the late fee.
  • Reconcile GSTR-2B before claiming ITC. Most Section 50(3) interest exposure on wrongly-availed-and-utilised ITC starts as a 2A/2B mismatch that no one cleaned up. Monthly reconciliation prevents the build-up.
  • Verify e-way bill compliance before dispatch. The Section 129 penalty is the highest per-rupee penalty in the GST regime. A 30-second check of the e-way bill, the invoice value, and the validity period prevents a 200%-of-tax penalty.
  • Respond to ASMT-10, DRC-01A and DRC-01 within the prescribed window. Pre-SCN voluntary payment and within-30-days-of-SCN payment are the cleanest penalty collapsers — non-fraud cases close at zero penalty; fraud cases drop from 100% to 15% (pre-SCN) or 25% (within 30 days of SCN). The exact sub-section reference is Section 73/74 for periods up to FY 2023-24 and Section 74A for FY 2024-25 onwards.
  • Do not contest the fraud characterisation casually — but do contest it where the facts support a non-fraud reading. Across both the old Section 73/74 regime and the unified Section 74A regime, a non-fraud finding caps penalty at 10% while a fraud finding takes it to 100%. The legal work to push the characterisation in the right direction often pays for itself many times over.

Bottom Line

GST penalties read as a long list, but the underlying logic is short. Late fees under Section 47 are formulaic and turnover-banded. Interest under Section 50 is mechanical and runs at 18% on the right base (cash-only for delays, availed-and-utilised credit for wrong ITC). General penalty under Section 125 is the residual catch-all at Rs. 25,000. Section 122(1) handles specific contraventions at Rs. 10,000 or tax-equivalent. Demand-route penalties bifurcate by intent: 10% of tax for non-fraud, 100% for fraud — the operative section being Section 73/74 for periods up to FY 2023-24 and the unified Section 74A for FY 2024-25 onwards. Section 129 deals with goods-in-transit at 200% of tax, with a higher exposure if the owner does not come forward. Section 47(2) handles annual return delays, banded by turnover with reduced caps for taxpayers up to Rs. 20 crore.

The amount payable in any specific case turns on which of these provisions the department invokes, the assessee's turnover band, and crucially the fraud-versus-non-fraud line. Each of these is a separate fight, and the early-payment windows in Sections 73, 74 and 74A are the most under-used penalty-reduction levers in the regime. Knowing which lever applies to your specific facts — before the show cause notice, not after the order — is what separates a clean closure from a multi-year appellate journey.
