GST applies to construction activities across various sectors, whether it is residential, commercial, or public infrastructure projects.The application depends on multiple factors, such as the stage of the property, the nature of the services, and whether the project involves works contracts.

Under-Construction Properties

GST applies to under-construction properties intended for sale. Properties that have completed the construction process and received a completion certificate are exempt from GST.

Affordable Housing

Construction of affordable housing projects attracts a reduced GST rate of 1%. These properties must meet specific criteria to benefit from this reduced rate.

Works Contracts

Works contracts are often bundled, involving both services and materials. The applicable work contract HSN codes will determine the GST rate for the project.

In some cases, GST exemptions apply to construction services and transactions involving construction materials. Here are some common exemptions:

Completed Properties

GST does not apply to completed properties or those with a completion certificate. If the property is sold after completion, it is exempt from GST.

Land Transactions

GST does not apply to land sales, as land is exempt from GST under the law.

Affordable Housing

Projects that meet the affordable housing criteria benefit from reduced GST rates of 1%,
providing relief to developers and buyers.

Labour-only Contracts

Certain labour-only contracts, especially under government schemes like PMAY, are exempt from GST.

Let’s consider an example of how GST is calculated on a construction project:

Service Component

If the agreement value for a residential complex is ₹50 lakh with an 18% GST rate, the GST payable on services would be:

• GSTonServices=₹50,00,000×18%=₹9,00,000\text{GST on Services} = ₹50,00,000 \times 18\% = ₹9,00,000GSTonServices=₹50,00,000×18%=₹9,00,000

Material Component

If materials worth ₹10 lakh are used at an 18% GST rate, the GST payable on materials would be:

• GSTonMaterials=₹10,00,000×18%=₹1,80,000\text{GST on Materials} = ₹10,00,000 \times 18\% = ₹1,80,000GSTonMaterials=₹10,00,000×18%=₹1,80,000

Total GST

• The total GST payable on the project would be ₹9,00,000 + ₹1,80,000 = ₹10,80,000.

This simplified example demonstrates how GST is applied to both construction services and materials with different components.

Input Tax Credit (ITC) allows businesses to reduce their GST liability by claiming credits for taxes paid on inputs used in their operations. However, there are restrictions on claiming ITC for construction-related expenses:

ITC Availability

ITC is available for construction materials and services used in taxable construction activities. However, ITC is not available for the construction of immovable property unless used for business purposes.

Non-Eligibility for Residential Projects

ITC cannot be claimed on the construction of residential property unless the property is intended for business use, such as rental properties.

Eligible ITC on Works Contracts

Contractors engaged in works contracts can claim ITC on materials and services used in the contract, provided they meet the eligibility criteria.

Despite the simplification brought by GST, the construction sector still faces several challenges, such as:

Compliance

Understanding and complying with GST requirements can be challenging, especially for small and medium-sized contractors.

Cash Flow Issues

The need to pay GST on an accrual basis, even before receiving payment from clients, can lead to cash flow problems.

Classification and Rates

Determining the correct classification and applicable GST rates for different construction activities and materials can be confusing, leading to potential disputes with tax authorities.

Frequent Changes in Regulations

The construction industry needs to stay updated on the changing GST rates and exemptions for construction materials and services.
