Applicability of GST on Construction in India
Goods and Services Tax (GST) plays a significant role in the taxation of construction activities across India. Understanding when and how GST applies can help stakeholders in the construction sector ensure compliance and optimise their tax liabilities. Below are the key aspects of GST applicability on construction:
Types of Construction Activities Covered by GST
- Private Construction: Involves residential projects intended for individual use, such as single-family homes and villas.
- Commercial Construction: Includes buildings designed for business purposes, such as offices, retail spaces, hotels, and malls.
- Residential Complexes: Encompasses the development of flats, housing societies, and apartment complexes.
GST on Under-Construction Properties
- Classification as Supply of Service: Any property that is still under construction and intended for sale is classified as a supply of service under GST laws.
- GST Liability: Applicable GST rates are charged on the value of the under-construction property. Developers and contractors are responsible for remitting GST based on the property's construction stage and value.
GST Exemption for Completed Properties
Ready-for-Sale Properties: Properties that are fully constructed, completed, and available for immediate sale are exempt from GST. Since these properties are not in the construction phase, they do not attract GST.
Factors Influencing GST Applicability on Construction Service
Type of Construction:
Residential vs. Commercial: Different GST rates and rules may apply depending on whether the project is residential, commercial, or industrial.
Nature of the Transaction:
- Sale: Direct sale of under-construction property attracts GST.
- Leasing/Renting: Construction intended for leasing or renting for commercial purposes may have specific GST treatments.
- Additional Services: Ancillary services related to construction might also be subject to GST.
Status of the Parties Involved:
- Buyers and Sellers: Their roles determine GST obligations.
- Contractors: Responsible for applying and remitting GST on their services.
- Other Stakeholders: Investors, agents, and intermediaries may have specific GST responsibilities.
Exemptions and Concessions under GST Law
There are several exemptions and concessions available under GST law for the construction sector:
- Affordable Housing Projects: Construction work on affordable housing is taxed at a reduced GST rate of 1%, applicable to residential properties with a carpet area of up to 60 square meters in metropolitan cities and up to 90 square meters in non-metropolitan cities, valued at ₹45 lakhs or less.
- Property Resale: GST is not applicable when reselling properties.
- Buying/Selling Apartments for Residence: Transactions involving the purchase or sale of apartments intended for residential use are exempt from GST.
- Buying/Selling Land: GST does not apply to transactions involving land.
- Pradhan Mantri Awas Yojana (PMAY): Construction or enhancement services provided through pure labour contracts under PMAY are exempt from GST.
- Single Residential Units: Construction services through pure labour contracts for a single residential unit or part of a residential complex are also exempt from GST.
Additional Requirements under GST for Construction Services
- e-Way Bills: Required for transporting building materials like cement and steel only if the consignment value exceeds ₹50,000.
- Invoicing: Businesses involved in the supply of construction services must issue GST-compliant invoices if they are registered under GST.
GST Rate for Construction Services
Under the new GST structure effective 22 September 2025, the standard GST rate for most construction services remains 18%, with a few important exceptions:
- Affordable housing projects continue to enjoy a reduced 1% GST rate (without input tax credit).
- Government-notified infrastructure projects such as roads, bridges, and irrigation works attract a 5% GST rate.
For construction materials, the applicable GST varies by item: cement is taxed at 28%, bricks at 12%, and sand at 5%. These rates play a crucial role in project costing and budgeting for developers, contractors, and property buyers.
GST Rate and HSN Code for Construction Services
Understanding the applicable GST rates and HSN (Harmonized System of Nomenclature) codes for various construction activities is essential for compliance and accurate tax calculation. Below is a detailed overview of the GST rates and corresponding HSN codes for different types of construction services in India:
| Construction / Works Contract Activity | GST Rate* | HSN / SAC Code |
|---|---|---|
| Affordable housing apartments (projects started on or after 1 Apr 2019) – without ITC | 1 % | 9954 |
| Non-affordable residential apartments (under-construction) – without ITC | 5 % | 9954 |
| Commercial apartments / commercial real estate projects (under-construction) | 18 % | 9954 |
| Works contract services (material & labour supplied by contractor) | 18 % | 9954 |
| Works contract services (pure labour only) | 18 % | 9987 |
| Government / local authority contracts for roads, bridges, dams, irrigation, etc. (notified public works) | 5 % | 9954 |
| Composite supply of works contract & goods (value of goods < 25 % or ≥ 25 %) – general cases | 18 % | 9954 |
*Rates shown are the net GST rates after deduction of one-third of the value towards land, wherever applicable, as per CBIC notifications.
Key Takeaways
- Residential projects: 1 % (affordable) and 5 % (non-affordable) rates continue without input-tax credit (ITC).
- Commercial projects & most works contracts: fall under the 18 % slab with ITC.
- Government-notified infrastructure works (roads, bridges, irrigation) enjoy a reduced 5 % rate.
This table replaces the older 12 % classifications and aligns with the new GST reforms effective 22 Sept 2025.

GST for Under Construction Property
When purchasing an under-construction property, it's crucial to understand how Goods and Services Tax (GST) is applied. The total GST payable comprises two main components: the service component (construction services) and the material component (construction materials). Here's a step-by-step guide to calculating GST on an under-construction property with a practical example.
Service Component
The GST rate for construction services varies based on the type of project:
- Standard Projects: 18% GST
- Affordable Housing Projects: 1% GST
Example:
Consider a property with an agreement value of ₹50 lakhs falling under the standard category with an 18% GST rate.
2. Material Component
The GST rate for construction materials depends on the specific items used, but generally, it is 18%.
If the cost of construction materials amounts to ₹10 lakhs, the GST payable on materials is calculated as follows:
3. Total GST on the Property
To determine the total GST payable on the under-construction property, simply add the GST from both components:
Calculation:
Summary of the Example:
- Agreement Value: ₹50,00,000
- GST on Service Component (18%): ₹9,00,000
- Material Cost: ₹10,00,000
- GST on Material Component (18%): ₹1,80,000
- Total GST Payable: ₹10,80,000
ITC Availability on GST Paid During Construction
Understanding the eligibility for Input Tax Credit (ITC) on GST paid during construction is crucial for developers, contractors, and property owners. According to Section 17(5), clauses (c) and (d) of the CGST Act, ITC is restricted in the following scenarios:
Work Contract Services for Immovable Property:
- Ineligible for ITC: Expenses incurred on work contract services specifically for constructing immovable property are not eligible for ITC.
- Exception: ITC can be claimed for expenses related to input services that are used to complete the supply of work contract services or for constructing plants and machinery.
Renovation or Repair:
- Ineligible for ITC: Costs associated with the renovation or repair of a property do not qualify for ITC.
Note: Despite these restrictions, construction companies, builders, and promoters can still claim ITC for eligible expenses under the exceptions mentioned above.
Supreme Court Ruling (3rd October 2024)
On 3rd October 2024, the Supreme Court delivered a pivotal judgment clarifying the eligibility of GST Input Tax Credit for construction expenses related to commercial rental services. The key highlights of the ruling are as follows:
Eligibility for ITC on Commercial Rentals:
- Condition: If the construction of a building is essential for providing services such as leasing or renting for commercial activities, it qualifies for ITC.
- 'Plant' Exception: This falls under the ‘plant’ exception in Section 17(5)(d) of the CGST Act, which allows ITC claims on construction materials used for constructing plants and machinery, even though ITC is generally prohibited for immovable property construction.
Latest Updates

Key Recommendations from the 55th GST Council Meeting on Construction Materials
- Reduction in GST for AAC Blocks: Autoclaved Aerated Concrete (AAC) Blocks containing more than 50% fly ash will now be categorised under HS code 6815. This reclassification reduces the GST rate from 18% to 12%, making these environmentally friendly blocks more cost-effective.
- Amendment to Section 17(5)(d) of the CGST Act: The term "plant or machinery" will be updated to "plant and machinery". This change is applied retrospectively from July 1, 2017, ensuring consistency with the explanations provided at the end of Section 17.
3rd October 2024
Supreme Court Ruling on GST Input Tax Credit for Construction (October 3, 2024)
The Supreme Court has provided clarity on the eligibility of claiming Input Tax Credit (ITC) under GST for construction related to rental services used for commercial purposes. The landmark decision states that:
- Construction Essential for Commercial Activities: If a building’s construction is necessary for providing services like leasing or renting for commercial activities, it qualifies under the ‘plant’ exception in Section 17(5)(d) of the CGST Act.
- Implications of Section 17(5)(d): This section generally prohibits ITC claims on construction materials used in the construction of immovable property. However, the exception for plant and machinery allows businesses to claim ITC on construction costs if the property is used for commercial service provision.
Conclusion
In conclusion, understanding GST in construction is essential for developers, contractors, and property owners to ensure compliance and optimize financial outcomes. The GST on construction services generally stands at 18%, while affordable housing projects benefit from a reduced GST rate on construction services of 1%. For under-construction properties, GST is applicable as these are considered a supply of service, whereas completed properties ready for sale are exempt from GST.
Additionally, the GST on construction materials varies depending on the type of material, ranging from 5% to 28%, which should be considered when calculating total tax liability.
