Section 8 of the Central Goods and Services Tax Act, 2017 deals with the tax liability on composite supplies and mixed supplies. It provides the method for determining which tax treatment should apply when a single transaction contains two or more supplies of goods, services, or both.
This section is important because businesses often supply multiple goods or services together. In such cases, GST law needs to determine whether the transaction is a composite supply or a mixed supply and, consequently, which GST rate should apply.
Section 8 contains two basic rules:
- A composite supply is taxed as the supply of its principal supply.
- A mixed supply is taxed as the particular supply that attracts the highest rate of tax.
To understand Section 8 properly, it is necessary to also understand the definitions of composite supply, mixed supply and principal supply under Section 2 of the CGST Act.
What is Section 8 of the CGST Act?
Section 8 is titled:
“Tax liability on composite and mixed supplies.”
The section provides the rules for determining tax liability when a transaction qualifies as either a composite supply or a mixed supply.
Section 8 states:
“The tax liability on a composite or a mixed supply shall be determined in the following manner, namely:—
(a) a composite supply comprising two or more supplies, one of which is a principal supply, shall be treated as a supply of such principal supply; and
(b) a mixed supply comprising two or more supplies shall be treated as a supply of that particular supply which attracts the highest rate of tax.”
Therefore, Section 8 essentially establishes two different tax rules.
| Type of Supply | GST Treatment |
|---|---|
| Composite Supply | Taxed as the principal supply |
| Mixed Supply | Taxed at the highest applicable rate among the supplies |
Why is Section 8 Important Under GST?
A single transaction may contain several goods or services.
For example, a business may sell a product along with:
- Packing
- Transportation
- Insurance
- Installation
- Warranty
- Other related services
If these components are supplied together, simply applying the GST rate of each individual component may not always be the correct approach.
GST law therefore provides specific rules for determining the tax treatment of such bundled supplies.
Section 8 makes the distinction between naturally bundled supplies and artificially bundled supplies important.
What is a Composite Supply?
The term “composite supply” is defined under Section 2(30) of the CGST Act.
A composite supply means a supply made by a taxable person to a recipient consisting of two or more taxable supplies of goods or services or both, or any combination thereof, which are:
- Naturally bundled;
- Supplied in conjunction with each other;
- Supplied in the ordinary course of business; and
- One of which is the principal supply.
Thus, merely supplying two or more items together does not automatically make the transaction a composite supply.
The supplies must satisfy the statutory requirements.
Example of Composite Supply
The CGST Act itself provides an illustration involving goods that are packed and transported with insurance.
For example, suppose a supplier sells goods and, as part of the same arrangement, provides:
- The goods;
- Packing;
- Transportation; and
- Insurance.
If these supplies are naturally bundled and supplied together in the ordinary course of business, the transaction can qualify as a composite supply.
In this example, the supply of goods is the principal supply.
Therefore, under Section 8(a), the entire composite supply is treated as a supply of the principal supply.
What is Principal Supply?
The expression “principal supply” is also important.
Under Section 2(90), principal supply means the supply which constitutes the predominant element of a composite supply and to which any other supply forming part of that composite supply is ancillary.
In simple words, the principal supply is the main supply, while the other components are supporting or ancillary supplies.
Example
Suppose a customer purchases a refrigerator from a retailer and the retailer also provides packing and transportation as part of the same bundled transaction.
If the goods are the main element and transportation and packing are ancillary to that supply, the refrigerator can be considered the principal supply.
Under Section 8, the composite supply is treated as a supply of that principal supply.
Tax Treatment of Composite Supply Under Section 8(a)
Section 8(a) provides a straightforward rule.
When a composite supply contains two or more supplies and one of them is the principal supply, the entire composite supply is treated as a supply of the principal supply.
Therefore, the tax treatment follows the principal supply.
Example
Suppose a business supplies a machine together with:
- Packing;
- Transportation; and
- Insurance,
as a naturally bundled package.
If the machine is the principal supply, the composite supply is treated as a supply of the machine.
The GST rate applicable to the principal supply is therefore relevant for determining the tax liability on the composite supply, subject to the applicable GST provisions.
What is a Mixed Supply?
The term “mixed supply” is defined under Section 2(74) of the CGST Act.
A mixed supply means two or more individual supplies of goods or services, or any combination thereof, made together by a taxable person for a single price, where the combination does not constitute a composite supply.
The important distinction is that the supplies in a mixed supply are not naturally bundled in the manner required for a composite supply.
Example of Mixed Supply
CBIC gives the example of a package containing items such as:
- Canned foods;
- Sweets;
- Chocolates;
- Cakes;
- Dry fruits;
- Aerated drinks; and
- Fruit juice,
when these items are supplied together for a single price.
If these individual items can be supplied separately and the package does not qualify as a composite supply, it can be treated as a mixed supply.
Tax Treatment of Mixed Supply Under Section 8(b)
Section 8(b) provides that a mixed supply consisting of two or more supplies is treated as a supply of the particular item that attracts the highest rate of tax.
This is different from the rule applicable to composite supply.
Example
Suppose a business sells a gift package for a single price containing three taxable products:
| Product | GST Rate |
|---|---|
| Product A | 5% |
| Product B | 12% |
| Product C | 18% |
If the package qualifies as a mixed supply, Section 8(b) provides that the mixed supply is treated as the supply attracting the highest rate, which in this example is 18%.
Therefore, the highest applicable GST rate becomes relevant to the tax treatment of the mixed supply.
Difference Between Composite Supply and Mixed Supply
This is one of the most important concepts under Section 8.
| Composite Supply | Mixed Supply |
|---|---|
| Contains two or more taxable supplies | Contains two or more individual supplies |
| Supplies are naturally bundled | Supplies are not naturally bundled |
| Supplied in conjunction with each other | Supplied together for a single price |
| One supply is the principal supply | No principal supply in the sense required for composite supply |
| Taxed as the principal supply | Taxed at the highest rate applicable to the supplies |
| Example: goods with packing, transport and insurance | Example: a single-price package containing unrelated products |
CBIC explains that the essential difference is whether the supplies are naturally bundled and whether one supply is the principal supply.
Composite Supply vs Mixed Supply: Simple Explanation
The difference can be understood with a simple question:
Composite Supply
Ask:
“Are these supplies naturally connected and normally supplied together, with one main supply?”
If yes, the transaction may be a composite supply.
Mixed Supply
Ask:
“Are separate supplies simply combined and sold together for one price, without being a naturally bundled composite supply?”
If yes, the transaction may be a mixed supply.
The actual classification depends on the statutory definitions and facts of the transaction.
What Does “Naturally Bundled” Mean?
“Naturally bundled” is a key concept in identifying a composite supply.
It generally means that the individual supplies are commonly provided together as part of the normal business practice and are naturally associated with one another.
For example, CBIC uses the supply of goods along with packing, transportation and insurance as an illustration of a composite supply.
The fact that multiple items are included in one invoice does not by itself establish that the supplies are naturally bundled.
The nature of the transaction and the normal business practice need to be considered.
Does a Single Invoice Mean It Is a Composite Supply?
No.
The fact that several goods or services appear on one invoice or are charged together does not automatically make them a composite supply.
The statutory requirements of Section 2(30) must be satisfied.
The supplies must be naturally bundled and supplied in conjunction with each other in the ordinary course of business, and one must be the principal supply.
Therefore, the classification should be based on the actual nature of the transaction rather than simply the invoice format.
Does a Single Price Mean It Is a Mixed Supply?
A single price is an important element of the definition of mixed supply, but it is not the only requirement.
The transaction must involve two or more individual supplies made together for a single price and must not constitute a composite supply.
Therefore, a transaction should first be examined to determine whether it qualifies as a composite supply. If it does not and the other requirements are satisfied, it may qualify as a mixed supply.
Section 8 and GST Rate
Section 8 determines which supply’s tax treatment should apply.
For a composite supply, the principal supply determines the treatment.
For a mixed supply, the supply carrying the highest GST rate determines the treatment.
This can have a significant effect on the tax payable by the supplier.
Composite Supply
Principal supply → Applicable tax treatment
Mixed Supply
Highest GST rate → Applicable tax treatment
Example: Composite Supply
Suppose a company sells a computer along with:
- Packing;
- Transportation; and
- Insurance,
under a single arrangement.
Assume these components are naturally bundled and the computer is the principal supply.
The transaction can qualify as a composite supply.
Under Section 8(a), the transaction is treated as a supply of the principal supply.
Therefore, the GST treatment follows the principal supply.
Example: Mixed Supply
Suppose a business sells a festive package for one price containing:
- Chocolates taxed at 18%;
- Dry fruits taxed at 5%;
- A food item taxed at 12%.
If the package does not qualify as a composite supply and satisfies the definition of mixed supply, Section 8(b) applies.
The package is treated as the supply attracting the highest rate of tax, which in this example is 18%.
The exact GST rate applicable to any actual product should always be checked against the current rate notification because GST rates can change.
Another Example of Composite Supply
Consider a hotel or service provider that provides a naturally bundled package in which one service is clearly the principal element and other services are ancillary.
If the transaction satisfies the definition of composite supply, Section 8 requires the tax treatment to follow the principal supply.
However, not every package offered by a business automatically qualifies as a composite supply. The specific facts and applicable classification rules must be examined.
Another Example of Mixed Supply
Suppose a business creates a gift basket containing several unrelated products and sells the complete basket for a single consolidated price.
If:
- The items are individually available;
- They are not naturally bundled;
- They are sold together for one price; and
- The transaction does not qualify as a composite supply,
the transaction may qualify as a mixed supply.
In that situation, Section 8(b) applies and the highest applicable GST rate among the individual supplies determines the tax treatment.
Section 8 and Section 2 Definitions
Section 8 cannot be understood properly without referring to the relevant definitions in Section 2.
The important definitions are:
Section 2(30) – Composite Supply
Defines composite supply.
Section 2(74) – Mixed Supply
Defines mixed supply.
Section 2(90) – Principal Supply
Defines principal supply.
Together, these provisions explain:
What is being supplied → How the supplies are bundled → Which supply is principal → Which GST treatment applies.
Section 8 and Schedule II
Schedule II also becomes relevant when determining whether a particular activity is a supply of goods or a supply of services.
However, Section 8 deals specifically with the tax liability on composite and mixed supplies.
Therefore, the legal analysis may involve several provisions.
For example:
Section 7 → Determine whether there is a supply
Section 2 → Determine whether it is composite or mixed
Schedule II → Determine goods/services classification where applicable
Section 8 → Determine the tax treatment of composite or mixed supply
This sequence helps in understanding the structure of GST law.
Section 8 and Section 7
Section 7 and Section 8 perform different functions.
| Section 7 | Section 8 |
|---|---|
| Scope of supply | Tax liability on composite and mixed supplies |
| Determines what constitutes supply | Determines treatment of composite or mixed supply |
| Works with Schedules I, II and III | Applies specifically to composite and mixed supplies |
| Broad starting point | Applies after the relevant classification |
Therefore, Section 7 generally comes before Section 8 when analysing a transaction.
Section 8 and Section 9
Section 8 determines how a composite or mixed supply is treated for tax liability.
Section 9 is the provision dealing with the levy and collection of CGST on intra-State supplies, subject to the provisions of that section.
Therefore:
Section 7 → Scope of supply
Section 8 → Composite and mixed supply treatment
Section 9 → Levy and collection of CGST
These provisions form an important part of the structure of the CGST Act.
Why Correct Classification Matters
Correctly identifying a transaction as a composite or mixed supply can affect the amount of GST payable.
If a transaction is incorrectly treated as a composite supply when it actually qualifies as a mixed supply, the wrong tax treatment could be applied.
Similarly, treating a naturally bundled transaction as a mixed supply may result in a different tax rate being considered.
Therefore, businesses should examine:
- The nature of each component;
- Whether the supplies are taxable;
- Whether they are naturally bundled;
- Whether they are supplied in conjunction with one another;
- Whether there is a principal supply;
- Whether the transaction is supplied for a single price;
- Whether the transaction satisfies the definition of mixed supply; and
- The applicable GST rate notifications.
Important Points About Composite Supply
A composite supply generally requires:
- Two or more taxable supplies.
- The supplies may consist of goods, services or both.
- The supplies are naturally bundled.
- They are supplied in conjunction with each other.
- They are supplied in the ordinary course of business.
- One supply is the principal supply.
Once the transaction qualifies as a composite supply, Section 8(a) provides that it is treated as a supply of the principal supply.
Important Points About Mixed Supply
A mixed supply generally involves:
- Two or more individual supplies.
- The supplies may consist of goods, services or both.
- They are supplied together.
- They are supplied for a single price.
- The combination does not qualify as a composite supply.
Once the transaction qualifies as a mixed supply, Section 8(b) provides that it is treated as the supply attracting the highest rate of tax.
Common Mistakes in Understanding Section 8
Mistake 1: Every Package Is a Mixed Supply
Not every package is a mixed supply.
If the supplies are naturally bundled and one is the principal supply, the transaction may instead be a composite supply.
Mistake 2: Every Bundled Transaction Is a Composite Supply
This is also incorrect.
The supplies must satisfy the requirements of the definition of composite supply, including natural bundling and the existence of a principal supply.
Mistake 3: Highest GST Rate Always Applies
The highest-rate rule applies to mixed supplies under Section 8(b).
It does not apply to a composite supply.
For a composite supply, the tax treatment follows the principal supply.
Mistake 4: Single Invoice Automatically Means Mixed Supply
A single invoice does not by itself establish a mixed supply.
The actual nature of the transaction must be examined.
Mistake 5: Principal Supply Means Highest-Priced Item
Principal supply does not simply mean the most expensive item.
Section 2(90) refers to the supply that constitutes the predominant element of a composite supply and to which the other supplies are ancillary.
Key Points of Section 8 of CGST Act, 2017
The important points are:
- Section 8 deals with tax liability on composite and mixed supplies.
- A composite supply consists of two or more taxable supplies that are naturally bundled and supplied together, with one being the principal supply.
- Under Section 8(a), a composite supply is treated as a supply of the principal supply.
- A mixed supply consists of two or more individual supplies made together for a single price and does not qualify as a composite supply.
- Under Section 8(b), a mixed supply is treated as the supply attracting the highest rate of tax.
- The definition of composite supply is contained in Section 2(30).
- The definition of mixed supply is contained in Section 2(74).
- The definition of principal supply is contained in Section 2(90).
- Schedule II may be relevant when determining whether a qualifying supply is treated as a supply of goods or services.
- Correct classification is important because composite and mixed supplies follow different tax rules.
Conclusion
Section 8 of the CGST Act, 2017 provides the rules for determining the tax liability on composite and mixed supplies. A composite supply consists of naturally bundled taxable supplies supplied together in the ordinary course of business, with one supply being the principal supply. Under Section 8(a), the entire composite supply is treated as a supply of the principal supply.
A mixed supply, on the other hand, consists of two or more individual supplies made together for a single price and does not qualify as a composite supply. Under Section 8(b), the entire mixed supply is treated as the supply that attracts the highest rate of tax.
Therefore, the key distinction is simple: composite supply follows the principal supply, while mixed supply follows the highest tax rate. However, determining whether a particular transaction is composite or mixed requires careful examination of the actual nature of the supplies and the definitions provided under the CGST Act.
