Indirect Tax Laws

GST dominates and Customs is the reliable minority. The paper moves with the law, so currency of material matters more than volume of practice.

Indirect Tax is largely a GST paper with a Customs section that students routinely under-prepare and then find sitting there worth real marks. The GST questions test the same chain every attempt — is it a supply, when, where, at what value, and what credit is available — while Customs tests valuation, duty computation and procedure. Because GST changes frequently, the risk here is studying the right topic from the wrong year.

How the paper is built

Goods and Services Tax

~70–80 marks

Computation, application and provisions

The dominant section of the paper.

Customs and FTP

~20–30 marks

Valuation, duty computation and procedure

Compact, predictable and often under-prepared.

Where the marks sit

Bands follow the weightage published by ICAI for the current scheme. Read them as a guide to study order, not as a prediction of any one paper.

GST — supply, time, place and value of supply

Steady20–25%

The classification chain that opens most questions.

GST — input tax credit

Rising15–18%

Blocked credits, apportionment, reversal.

GST — registration, returns, payment and refunds

Steady15%

Threshold and timeline recall.

GST — assessment, audit, demand, appeals and penalties

Steady12–15%

Procedural, and reliably present.

Customs — valuation and duty computation

Steady12–15%

The most computational part of the Customs block.

Customs — procedures, exemptions and baggage

Steady10%

Short questions, cheap marks.

Foreign Trade Policy

Steady8%

Small, self-contained, frequently skipped.

Questions that repeat

These are the forms that come back attempt after attempt. Each one has an opening move — the thing to write down before you start computing.

01

GST liability computation with input tax credit

Every attempt10–14 marks

Outward and inward supplies, credit eligibility, and net liability in cash.

How to attack it

Tabulate with a reason column for every credit allowed or denied. The reasons carry marks independently of the final figure.

02

Classification chain question

Every attempt6–10 marks

Whether a transaction is a supply, its time, place and value.

How to attack it

Answer in the statutory order — supply, time, place, value. Skipping a link loses the mark for it even if the conclusion is right.

03

Customs duty computation

Most attempts8–12 marks

Assessable value from a transaction value with additions, then the duty ladder.

How to attack it

Build the assessable value line by line before computing any duty. The additions to transaction value are where the marks sit.

04

Procedural provision question

Every attempt4–6 marks

Registration, return, refund, appeal or penalty provisions under GST or Customs.

How to attack it

Memory work with a high return. State the rule, apply the timeline to the facts, conclude.

Your three hours

A starting plan for the paper. Adapt the order to your own strengths — the point is to walk in with an order decided, because deciding it in the hall is what leaves questions unattempted.

  1. 0–35

    Objective block

    Case scenarios first while reading stamina is high.

  2. 35–95

    GST computation

    Take the main GST liability and classification questions with full reason columns.

  3. 95–140

    Customs block

    Write the Customs answers. They are quicker than GST per mark — do not leave them stranded at the end.

  4. 140–180

    Remaining and review

    Finish the procedural questions and verify that every credit denial has a stated reason.

Avoidable losses

Every one of these costs marks after the work was already done. They are the cheapest marks on the paper to recover.

Skipping Customs and FTP

What it costs

20–30 marks of comparatively easy content

Do this instead

The Customs block is compact and its question forms are stable. Per hour of study it is the best-value section of the paper.

Studying GST from outdated material

What it costs

Right topic, wrong rule

Do this instead

GST moves. Confirm the amendments applicable to your attempt and prefer the current study material over older notes.

Concluding a classification question without the chain

What it costs

The marks for each link you skipped

Do this instead

Supply, time, place, value — write each step even when the conclusion is obvious. Each is separately marked.

How to prepare

  • Prepare Customs early, not last. It is finite, stable and worth a fifth to a quarter of the paper. Leaving it to the final week is the most common structural mistake in this paper.
  • Practise the ITC reason column. Writing the reason for every credit decision is a habit that has to be built in practice. It is where the marks are concentrated.
  • Track amendments as you study. One live sheet, updated continuously. In indirect tax the law is the thing that changes, not the technique.

How much of the paper is Customs?

Typically a fifth to a quarter, including Foreign Trade Policy. That is enough to decide a marginal result, and it is the section students most often leave to the last week. Its question forms are also more stable than GST's.

Why is currency of material such an issue here?

Because GST rules, rates and procedures are amended frequently, and the exam tests the position applicable to your attempt. Unlike a technique, an outdated rule gives you a confidently wrong answer with no signal that anything is off.

Is this paper mostly computation?

It is more balanced than it appears. The computations are prominent, but a large share of the marks sits in classification reasoning and procedural provisions — both of which are written answers rather than arithmetic.

Please note

Weightage bands follow the skill-wise and chapter-wise weightage published in the ICAI syllabus and study material for the current scheme. Frequency labels (Every attempt / Most attempts / Alternate attempts / Occasional) describe recurring question forms observed across recent past papers and are editorial guidance, not an ICAI statistic — no breakdown here predicts what will be asked. Paper patterns, marks splits and the MCQ share change between schemes and notifications: always confirm against the exam notification and study material for your attempt before planning around any figure on this page.
