One Paper, Two Tax Systems
CA Intermediate Paper 3 — Taxation — is one of the most marks-intensive papers in the CA Intermediate curriculum. It covers Income Tax Law (60 marks) and Goods and Services Tax (40 marks) in a single sitting. Both halves require regular updating for Finance Act changes and GST notifications, which makes this subject simultaneously high-reward (if current) and high-risk (if outdated).
Students who separate their preparation into two distinct study tracks — one for Income Tax, one for GST — consistently score better than students who jump between the two without a plan. The subjects are conceptually independent even though they share the same exam paper.
Income Tax (60 Marks): Syllabus Overview

High-Yield Topics: Where Marks Are Won
Income Tax
- PGBP computation: Disallowances (Section 40, 40A), deemed profits, maintenance of books — appears as a full 12–15 mark computation problem
- Capital Gains: Short-term vs long-term classification, indexation benefit, Section 54/54F/54EC exemptions — scenario questions are common
- Old vs New Tax Regime (Section 115BAC): Comparative computation — which regime is beneficial for a given individual is tested regularly since FY 2023-24
GST
- Input Tax Credit: The blocked credits under Section 17(5) list is a favourite MCQ area — motor vehicles, food, health insurance, works contract
- Composite vs Mixed Supply: Identifying the classification and its GST implication — commonly tested with practical scenarios
- Place of Supply: Interstate vs intrastate determination for services — particularly B2B vs B2C services
Preparation Sequence That Works
Complete Income Tax first — it is larger and requires more time. Within Income Tax, sequence: Basic Concepts → Salary → House Property → PGBP → Capital Gains → Other Sources → Clubbing & Set-off → Deductions → Tax Computation. Then take GST: Supply → Registration → Valuation → Place of Supply → ITC → Returns. This sequence follows the logical dependency of concepts in both systems.
💡 Taxation is an amendment-sensitive subject. Ensure your study material is updated to the Finance Act applicable for the relevant exam sitting. Use the e-mentor Planner to schedule both Income Tax and GST as separate daily blocks — mixing them in a single session reduces the contextual focus each requires.

Common Scoring Mistakes in Taxation Paper
- Not showing the tax computation format — writing the tax liability without the structured income computation table
- Using wrong assessment year — always verify whether the question specifies PY or AY
- Ignoring GST notifications and circulars — ICAI does incorporate recent GST Council decisions
- Treating old tax regime deductions as available under the new regime — they are not, and this distinction is tested
