Reading a show cause notice: the first thirty days
What to check before anyone starts drafting, why the period matters more than the merits, and the three things that quietly decide the matter years later.
Pre-deposit arithmetic under both regimes, the ceilings, the difference between an additional deposit and a total one, and the windows that no authority can extend.
The decision to appeal is usually presented as a question about the merits. In practice, in the first fortnight, it is a question about cash and about dates. Both are computable, and doing so early changes the decision more often than people expect.
Neither the GST law nor the Customs Act lets you argue an appeal without putting money down first. There is no stay application and no discretion. The deposit is a condition of the appeal being entertained, and once it is made, recovery of the balance stays suspended while the appeal is pending. That is the practical reason the figure matters more than the merits in the first two weeks.
At the first appeal, the appellant pays in full the part of the demand that is admitted, and in addition a sum equal to ten per cent of the remaining tax in dispute, subject to a statutory ceiling Section 107(6), CGST Act 2017. Where the order involves only a penalty and no tax, the percentage runs on the penalty.
At the Tribunal, a further ten per cent of the tax in dispute is payable, and the statute says it is in addition to what was paid under the first appeal provision Section 112(8), CGST Act 2017. That word matters. Two stages of appeal under this law mean two deposits, not one topped up.
The Customs Act works differently. Seven and a half per cent of the duty, or of the penalty where only a penalty is in dispute, is deposited for an appeal to the Commissioner (Appeals), and ten per cent where the appeal lies to the Tribunal, subject to a ceiling Section 129E, Customs Act 1962. The requirement at the Tribunal stage is expressed as a total rather than as an addition, so what was deposited at the first appeal counts towards it and only the balance is paid.
The two regimes therefore produce very different second appeal numbers on the same facts. That is not an anomaly to be smoothed over. It is the statute, and it has to be computed regime by regime.
Both regimes cap the deposit. Under the GST law the ceiling applies separately under the central and the state enactment. Under the Customs Act there is a single ceiling. On a very large demand the cap is what makes an appeal fundable at all, and it is worth identifying early because it changes the shape of the decision.
This is where most avoidable losses happen.
Condonation is not a second deadline. It is a discretion exercised on sufficient cause shown, and pressure of work is not sufficient cause. Treat the first date as the date.
It is not a payment of the demand. Where the appeal succeeds the amount is returned, and the statutes provide for interest on it. It should be accounted for accordingly, and it is worth saying so to a board that reads the deposit as a loss crystallising.
Once the number and the dates are known, the decision becomes a comparison rather than an argument. Four things go into it.
The deposit is an input to the decision, not the decision. But it is a number, it is knowable on day one, and businesses that work it out on day one make better decisions than those that work it out on day forty.

A Special Valuation Branch reference is a process, not an accusation. What goes into the reply, why royalties are the hard part, and how a loading survives for years.
Both are computable on day one, and the appeal decision is a different conversation once they are on the table.
