Basics of Goods and Services Tax for CS Executive

Basics of GST covers why India moved to a destination-based, dual GST, the constitutional framework, and four provisions: power not to recover tax under general practice (sections 11A CGST and 6A IGST), GST practitioners (section 48), compliance rating (section 149) and authorised representatives (section 116). Learn the provision, apply it to facts, then conclude.

What this chapter covers

This chapter is the entry point to the GST part of Paper 7 Tax Laws and Practice. It explains the indirect tax background, why GST replaced many separate taxes, and how the Centre and States share the power to tax under the constitutional framework. You also meet the dual model: CGST and SGST or UTGST on intra-State supplies, and IGST on inter-State supplies.

The second half is about specific provisions that are easy to learn and easy to score on. These are the power to waive tax not levied or short-levied because of a general practice (section 11A of the CGST Act and section 6A of the IGST Act), GST practitioners (section 48), and the GST compliance rating (section 149). Section 116 on appearance by an authorised representative links closely to the practitioner provisions.

The chapter connects to everything that follows in Indirect Tax. Levy, supply, registration, input tax credit, returns and recovery all sit on the base you build here. If the model and the framework are clear, the later chapters are easier to follow.

This chapter is short, mostly conceptual, and based on clear statutory wording, so it is a good place to secure marks in Part II of Paper 7 (Indirect Tax, 40 marks). Questions can ask you to explain a provision, state who may act for a registered person, or apply a rule to a small fact pattern. Because the answers follow the section text closely, careful learning pays off directly, and the ideas here help you understand later GST chapters.

Basics of Goods and Services Tax: topics in the order to study them

  1. 1Introduction to GST and Indirect Tax BackgroundStart with why GST exists and what it replaced, so the later rules make sense.
  2. 2GST Model and Constitutional FrameworkNext, learn the dual model and who has the power to tax, since every later provision rests on it.
  3. 3Power Not to Recover Tax Under General PracticeThis is the most technical provision, with conditions to learn, so study it once the model is clear.
  4. 4GST PractitionersSection 48 is short and also leads into who can appear for a taxpayer under section 116.
  5. 5GST Compliance RatingFinish with section 149, the shortest provision, which is easy to revise last.

How to prepare Basics of Goods and Services Tax

Treat this chapter as a mix of background to understand and short sections to learn almost word for word.

  1. Read the background and model topics once for understanding. Write in your own words why GST is destination-based and dual.
  2. Make a one-page chart of CGST, SGST or UTGST, and IGST, with which applies to which kind of supply.
  3. Learn sections 11A (CGST) and 6A (IGST) together. They are parallel, differing only in the tax named. Note the two conditions, the Council's recommendation and the notification.
  4. Learn section 48 in three parts: the rules are prescribed, the registered person may authorise a practitioner to furnish returns, and responsibility for correctness stays with the registered person.
  5. Read section 116 beside section 48 and list who can be an authorised representative and who is disqualified.
  6. Learn section 149: the score is assigned by the Government, based on prescribed parameters, updated periodically and placed in the public domain.
  7. Practise writing answers in this order: provision, facts, conclusion, naming the Act and section.
