The Pass Rate Crash — What Actually Happened

Group II pass rate dropped from 25.26% (Sep 2025) to 9.76% (Jan 2026) — a swing of more than 15 percentage points in a single attempt. Less than 1 in 10 cleared Group II in Jan 2026.

The simplistic explanation is “hard papers.” The paper-led explanation is more precise: amendment cutoffs, evaluation benchmarks, and a deliberate shift towards application.

DT (Paper 4): Sep 2025 vs Jan 2026 — Full Comparison

Structure remained constant: 6 questions, Q1 compulsory (14 marks), attempt any 4 of remaining 5, total 70 marks, 3 hours, AY 2025–26. The difference was task design and marking expectation.

Q1 — Compulsory: Business income computation

Q2 — Capital gains + special entities

Q3 — Charitable trust + individual with foreign income

Trust computation (12AB / allied logic) appeared in both papers. The “no DTAA” double-taxation relief for individuals also repeated with changed facts — meaning ICAI is testing the framework, not memorised sums.

Q4 — TDS/TCS + Transfer pricing

Transfer pricing repeated, but method rotated. May 2026 could rotate again (TNMM / RPM / Profit Split). Strategy: prepare all methods as a set.

Q5 — Procedural (choose 2 of 3): marking benchmark changed

The insertion of application is not cosmetic. It signals what evaluators will reward: your answer must connect provision to the facts (dates, amounts, parties), not just reproduce the law.

IDT (Paper 5): Sep 2025 vs Jan 2026 — Full Comparison

Structure remained constant (Q1 compulsory, attempt any 4, total 70, 3 hours). The amendment cutoff moved from 28 Feb 2025 (Sep 25) to 30 June 2025 (Jan 26), and Jan 26 used that window aggressively.

Q1 — Compulsory GST computation

Q2 — Valuation + customs assessable value + RCM rotation

Both papers tested assessable value with multiple dates/exchange rates. The consistent trap: correct date selection (bill of entry vs entry inward) and correct application for BCD/IGST.

Q3 — Place/time of supply + customs

Baggage Rules repeated with different passenger facts. That’s a strong signal: prepare the chapter as a framework (traveller category → allowance → prohibited goods → consequences), not as one solved question.

Q4–Q6 — Procedure became sharper (returns/refund/appeals + OR options)

Sep 25 leaned on interest mechanics; Jan 26 leaned on refund timelines and procedural precision. Jan also introduced an OR option within a sub-part — indicating more “choice within theory” going forward.

ICAI deliberately tested both frameworks across attempts: Sep 25 used 74A (new SCN framework theme) while Jan 26 tested 74 (old). For May 2026, treat “old vs new framework” as a compulsory comparison area.

Topics That Repeated in BOTH Attempts — Highest Priority for May 2026

If a topic appears in Sep 2025 and Jan 2026, it signals ICAI’s “core testable basket.” These are the topics that should not be left to chance.

Direct Tax — repeating topics

Indirect Tax — repeating topics

The Critical Shift ICAI Made Between the Two Attempts

Beyond topics, ICAI changed how marks are earned. Three shifts matter for May 2026 execution.

Shift 1 — “Application” became explicit

Sep: Issue → Provision → Analysis → Conclusion. Jan: Issue → Provision → Analysis & application → Conclusion. That single word changes answer-writing discipline.

Shift 2 — Q1 became a two-task question

Jan Q1 often required compute + advise/evaluate. Students who completed only computation left marks unclaimed. For May 2026, practice Q1 as two deliverables, not one.

Shift 3 — theory moved from “definitions” to “scenarios”

Jan theory demanded precise conditions, timelines, and scenario mapping. Reading once is not enough — you must prepare theory in a structure (trigger → provision → conditions → consequence).

The Amendment Gap — The Hidden Reason Group II Crashed

The amendment cutoff gap between attempts was ~4 months (Feb 28 → Jun 30). Jan 2026 used that gap as a filter: outdated notes weren’t merely “suboptimal” — they became risky.

What May 2026 Students Must Do Differently

Based on a paper-by-paper comparison, here is the high-yield execution blueprint for May 2026 — focused on what earns marks under the newer benchmark.

DT (Paper 4) — execution blueprint

• Train Q1 as “compute + evaluate.”

  Practice the second deliverable (rate regime / beneficial option / advisory conclusion) — not just computation.

• Transfer pricing: prepare all methods as a set.

  Sep tested CUP, Jan tested Cost Plus. Prepare TNMM/RPM/Profit Split with the same confidence.

• Buyback taxation (with foreign variation) is now core.

  It repeated. Treat it as non-negotiable.

• 12AB / trust computation is not optional.

  It repeated with changed facts. Prepare the framework, not one solved question.

• Answer-writing must show application.

  Use the facts (dates/amounts/parties) inside your analysis. Don’t write generic law notes.

• Amendment cutoff verification is mandatory.

  DT is the most amendment-sensitive paper. Confirm your material’s cutoff and patch gaps early.

IDT (Paper 5) — execution blueprint

• Q1 GST computation: practice like a speed + accuracy skill.

  Target 10 full mixed-entity questions. Build a method: classification → place of supply → ITC eligibility → output → net.

• RCM: know the notified services list, not just concepts.

  Questions rotate services. The constant is the framework and conditions.

• Customs assessable value: master the two-date/two-rate trap.

  Practice bill of entry vs entry inward logic and correct application for BCD/IGST.

• Baggage Rules: prepare traveller categories systematically.

  Different facts, same chapter. Prepare as a matrix: traveller type → allowance → prohibited goods → outcome.

• Old vs new SCN framework awareness.

  If ICAI is testing both across attempts, you must be fluent in comparisons and timelines.

• Write with provisions + clarifications where expected.

  Where circulars/notifications directly govern treatment, cite them as part of the answer structure.
