Penalty and interest: what the department can and cannot add
Two thirds of a typical GST demand is interest and penalty. They are computed by default and conceded by default.
Interest on delayed payment of tax arises under Section 50(1), confined by the proviso to the net cash liability where the return is filed late but before proceedings, and computed under Rule 88B. Interest on wrongly availed credit arises under Section 50(3) only where the credit is availed and utilised. Penalty arises under Section 73 or 74 with graded reductions for early payment, or under Section 122 for specified acts, subject to Section 126 for minor breaches and Section 75(13) against double penalty.
Interest, computed properly
Section 50(1) applies to tax not paid within the prescribed period. The proviso confines interest to the amount payable through the electronic cash ledger where the return for the period is furnished after the due date, except where proceedings under Section 73 or 74 have been initiated.
Rule 88B prescribes the manner. For a delayed return, interest is on the tax paid through the cash ledger, for the period of delay. For wrongly availed credit, interest runs from the date of utilisation.
Section 50(3) as substituted from 1 July 2017 requires the credit to be both wrongly availed and utilised. Rule 88B(3) treats credit as utilised when the ledger balance falls below the amount concerned.
The two most expensive default errors are interest on the gross liability where the proviso applies, and interest from availment where the credit was never utilised.
Penalty, and the reductions
Under Section 73: no penalty on payment before the notice under sub section (5), no penalty on payment within thirty days of the notice under sub section (8), and ten percent of the tax subject to a minimum on determination under sub section (9).
Under Section 74: fifteen percent before the notice, twenty five percent within thirty days of the notice, fifty percent within thirty days of the order, and otherwise equal to the tax.
Under Section 74A for 2024-25 onwards, a graded structure applies with the higher penalty where fraud, wilful misstatement or suppression is established.
Section 122 penalties are specific to the acts listed and Section 75(13) bars a second penalty for the same act.
Section 126 requires that no penalty be imposed for a minor breach, or for an omission easily rectifiable and made without fraudulent intent, and requires the officer to give reasons. Plead it expressly; it is rarely raised and rarely refused when it is.
Late fee, and the items that are not penalties
Late fee under Section 47 for delayed returns is a separate levy with its own caps and waivers, and it is not reduced by a successful appeal on the tax.
Section 125 provides a general penalty of up to twenty five thousand rupees where no specific penalty is prescribed. It cannot be used to supply a penalty the statute does not provide for a particular act.
Interest is compensatory and is not reduced on equitable grounds. The way to reduce interest is to reduce the tax or to correct the computation.
Exhibit — The four computations to run on every demand
| Computation | Provision | Common departmental error |
|---|---|---|
| Interest on delayed tax | Section 50(1) proviso with Rule 88B | Computed on gross liability instead of the net cash amount |
| Interest on wrongly availed credit | Section 50(3) with Rule 88B(3) | Computed from availment even where the credit was never utilised |
| Penalty with graded reduction | Sections 73(5) to (9), 74(5) to (11), 74A | Reduction not offered, or the thirty day window not communicated |
| Minor breach relief | Section 126 | Not considered at all; no reasons recorded |
Run all four before you decide whether to contest. The reduction in a typical demand is substantial and does not require winning on the merits.
What to do on Monday
Recompute interest under the Section 50(1) proviso and Rule 88B on every demand before responding.
Extract the credit ledger balances to establish whether disputed credit was ever utilised.
Plead Section 126 expressly for every minor or rectifiable breach.
Compute the graded reduction figures before deciding to contest, and record the decision.

Write to the GST practiceQuestions we are asked on this
Is interest automatic?
It arises by operation of law, but the computation is not automatic and is frequently wrong. Recompute it yourself.
Can penalty be waived entirely?
Under Section 126 for a minor or rectifiable breach, and under the payment provisions in Sections 73 and 74. Section 128A waived interest and penalty for the covered years.
Is interest payable on penalty?
No. Interest attaches to tax and to wrongly utilised credit.
Does a successful appeal on tax remove the late fee?
No. Late fee under Section 47 relates to the filing default and is unaffected.
Can the general penalty under Section 125 be added to a specific penalty?
It applies where no specific penalty is provided, and Section 75(13) bars a second penalty for the same act.
