SECTION 8 OF CGST ACT, 2017 – TAX LIABILITY ON COMPOSITE AND MIXED SUPPLIES

---

1. Introduction

Section 8 of GST Act deals with how tax liability is determined when a supply consists of more than one good or service.

👉 Section 7 answers “what is supply?”
👉 Section 8 answers “how much tax and at what rate?”

Thus, Section 8 is the logical continuation of Section 7.

Section 8 applies only when:

• There is a composite supply, or
• There is a mixed supply

---

2. Statutory Provision

Section 8 is contained in the Central Goods and Services Tax Act, 2017.

Text of Section 8 (Simplified)

1. Composite Supply → Tax rate of principal supply
2. Mixed Supply → Tax rate of highest taxed item

---

3. Meaning of Composite and Mixed Supply

Before understanding Section 8, we must understand definitions given in Section 2.

---

4. Composite Supply – Section 2(30)

Definition

Composite supply means:

A supply consisting of two or more taxable supplies of goods or services or both,
which are naturally bundled and supplied together in the ordinary course of business,
one of which is a principal supply.

---

Essential Elements of Composite Supply

1. Two or more supplies
2. Naturally bundled
3. Supplied together
4. One principal supply

---

Meaning of Principal Supply – Section 2(90)

Principal supply is the main supply, and other supplies are ancillary or incidental.

---

5. Examples of Composite Supply

• Hotel accommodation + breakfast
• Transport of goods + insurance
• Sale of machine + installation
• Construction contract (material + labour)

---

6. Tax Liability under Section 8(a)

👉 Entire composite supply is taxed at the rate applicable to principal supply.

Illustration

Hotel room (₹5,000) + breakfast (₹500)

Principal supply = Accommodation
Tax rate applicable = Rate of accommodation
Breakfast follows same rate.

---

7. Mixed Supply – Section 2(74)

Definition

Mixed supply means:

Two or more individual supplies of goods or services,
supplied together for a single price,
which are not naturally bundled.

---

Key Feature

Supplies can be supplied separately, but are bundled artificially.

---

8. Examples of Mixed Supply

• Gift hamper containing chocolates, wine, dry fruits
• Festival combo offers
• Electronics combo pack

---

9. Tax Liability under Section 8(b)

👉 Entire mixed supply is taxed at the highest rate applicable to any item.

Illustration

Gift hamper:

• Chocolates – 18%
• Perfume – 28%

➡️ Entire hamper taxed at 28%.

SECTION 8 – COMPLETE PROBLEM BASED MASTER ANALYSIS

(Composite Supply & Mixed Supply)

Under the Central Goods and Services Tax Act, 2017

---

PART 1 – CONCEPTUAL FOUNDATION (VERY DEEP ANALYSIS)

---

1. Why Section 8 Was Introduced?

Before GST:

• VAT taxed goods
• Service tax taxed services
• Courts faced difficulty in composite contracts

After GST:

• Everything is “supply”
• But rate confusion arises when multiple supplies are bundled

So Section 8 decides:

👉 How tax liability is determined when supply consists of more than one item.

---

2. Section 8 Text Simplified

If supply is:

(A) Composite Supply

→ Tax rate of principal supply

(B) Mixed Supply

→ Highest tax rate among items

---

3. Deep Understanding of “Naturally Bundled”

This is the MOST IMPORTANT concept.

Courts use following tests:

1. Are supplies normally provided together?
2. Is one supply dominant?
3. Would customer buy them separately?
4. Is separation artificial?

If answer shows natural connection → Composite.

If artificially clubbed → Mixed.

---

4. Judicial Background (Pre-GST Foundations)

---

1️⃣ State of Madras v. Gannon Dunkerley & Co.

Established that works contracts are composite in nature.

---

2️⃣ Bharat Sanchar Nigam Ltd v. Union of India

Explained distinction between goods and services in composite transactions.
