It’s important to differentiate between the nature of the work being done, as this impacts the GST rate applicable to the construction work.
- Types of Supply: The nature of the supply can be categorized into works contract, supply of goods, or a combination of both. Each has different GST implications.
- Contractual Agreements: GST may also vary based on whether the contract is for a government project, private development, or a public-private partnership.
GST Rates on Construction Work
The GST rates applicable to construction work typically range from 5% to 18%, depending on the specific services involved:
- 5% on construction of affordable housing.
- 12% on construction of residential complexes.
- 18% on commercial construction projects.
How to Calculate GST in Construction Estimate
Calculating GST in a construction estimate involves several steps. Here’s how to ensure accurate GST inclusion in your estimation:
- Identify the Nature of Supply: Determine whether it’s a works contract, supply of materials, or a service, as this affects the applicable GST rate.
