GST on Installation Charges Included in Product Price

A comprehensive guide on GST on installation charges included in the product price, including the composite supply treatment under Section 8 of the CGST Act.

Introduction

Many products — air conditioners, machinery, equipment, and furniture — are sold with installation included in the price. The question arises: How is GST applied when installation charges are included in the product price?

The answer depends on whether the supply is a composite supply or a mixed supply. This guide explains the legal framework and the practical implications.

Legal Framework: Section 2(30) and Section 8 of the CGST Act, 2017

Composite Supply

Section 2(30) defines a composite supply as a supply comprising two or more taxable supplies that are naturally bundled and supplied in conjunction with each other, one of which is a principal supply.

Tax Liability on Composite Supply

Section 8(a) provides that a composite supply is treated as a supply of the principal supply. The GST rate applicable to the principal supply applies to the entire composite supply.

Installation as Part of Composite Supply

When Installation is Ancillary

Where installation is ancillary to the supply of goods — that is, the installation is necessary for the goods to function as intended — the supply is a composite supply. The principal supply is the goods, and the GST rate applicable to the goods applies to the entire supply.

Examples

  • Air Conditioner with Installation: The AC is the principal supply; installation is ancillary. The entire supply is taxed at the GST rate applicable to the AC.
  • Machinery with Installation: The machinery is the principal supply; installation is ancillary. The entire supply is taxed at the GST rate applicable to the machinery.
  • Furniture with Assembly: The furniture is the principal supply; assembly is ancillary.

When Installation is a Separate Supply

Where installation is a separate supply — that is, the customer can choose whether or not to purchase installation — it may be treated as a separate supply. In such cases, GST is applied separately to the goods and the installation service.

GST Rate on Installation Services

Where installation is treated as a separate supply, it attracts 18% GST as a service.

Documentation Required

  • Supply Agreement: Documentation of the supply terms.
  • Invoice: Invoice showing whether installation is included or charged separately.
  • Work Completion Certificate: Certificate of installation.

Best Practices

  • Determine the Nature of Supply: Assess whether installation is ancillary or a separate supply.
  • Document the Agreement: Clearly document whether installation is included in the price.
  • Issue Proper Invoices: Issue invoices that reflect the correct GST treatment.
  • Maintain Records: Document all installation services.
  • Seek Professional Assistance: For complex supply arrangements, seek guidance.

Conclusion

Installation charges included in the product price are treated as part of a composite supply if the installation is ancillary to the supply of goods. The GST rate applicable to the goods applies to the entire supply. Where installation is a separate supply, it attracts 18% GST. Proper documentation is essential.
