CA Final Indirect Tax — High Marks, High Amendment Risk
CA Final Paper 8 (Indirect Tax Laws) covers GST and Customs Duty. With a 100-mark paper, it's one of the more scoring papers in CA Final — but only for students who track amendments. A student with outdated notes can easily lose 20–25 marks to Finance Act and GST notification changes.

GST vs Customs: Time Allocation
CA Final IDT is 100 marks across 3 hours. GST carries approximately 70 marks; Customs approximately 30 marks. Within GST, Input Tax Credit (ITC) and Place of Supply rules are the most marks-dense and the most discriminatory — students who understand them deeply score well above average, while those who memorise shallowly fail the application-based questions.
| Topic | Marks | Key subtopics |
|---|---|---|
| Input Tax Credit | 15–20 | Section 16 conditions, Section 17(5) blocked credits, ITC reversal |
| Place of Supply | 10–15 | Sections 10/11/12/13, B2B vs B2C, services with specific rules |
| Registration, Returns, Refund | 8–12 | Threshold, composition scheme, inverted duty refund |
| Assessment, Demand, Appeals | 8–10 | Scrutiny, best judgement, Section 73/74 demand notices |
| Customs — Valuation, Duty, Classification | 25–30 | Transaction value (Rule 4), HSN classification, IGCR, FTP |
ITC — Section 17(5) Blocked Credits: The Exam List
Section 17(5) lists ITC that cannot be claimed regardless of business use. Learn these as a fixed list — they appear as true/false scenario questions ("Can XYZ Ltd claim ITC on the following?"):
- Motor vehicles and other conveyances (except when used for further supply, transportation of goods, or passenger transport as a business)
- Food and beverages, outdoor catering, beauty treatment, health services, cosmetic surgery
- Membership of a club, health and fitness centre
- Travel benefits (leave/home travel concession) to employees
- Works contract services for construction of immovable property (except when used for further supply of works contract)
- Goods or services for personal consumption
- Goods lost, stolen, destroyed, written off or disposed of as gift/sample
Customs Valuation: Transaction Value Additions
Customs duty is charged on transaction value under Rule 4 of the Customs Valuation Rules 2007. What is added to the invoice price: cost of transport to India (CIF basis), insurance, loading, unloading, and handling charges up to the port of importation. What is excluded: post-importation charges such as installation or erection done in India. Practice 4–5 customs valuation numericals — they follow a fixed addition/deduction template and are fully scoreable with practice.
