GST rates on construction materials have a direct impact on project costs, housing affordability, and the overall feasibility of real estate developments. To support the sector, the government has rationalised GST slabs, removing the previous 28% rate on key inputs and moving most construction materials into the 18% and 5% brackets. This page provides an overview of the latest GST rates on cement, bricks, tiles, and other essential materials, along with their effect on construction costs. It also explains how GST 2.0 has simplified compliance, enhanced cost predictability, and promoted affordable housing, while highlighting practical considerations for builders, developers, and individual homebuyers.

What are the GST rates on construction materials?

GST on construction materials has been significantly rationalised to support the real estate sector. The 28% top rate has largely been removed for key materials such as cement, with most essential construction items now falling under either the 18% standard rate or the 5% concessional rate. This harmonisation allows developers and individual homebuilders to plan and manage project costs more predictably. You can refer to the GST state code list to see the applicable tax codes across different regions.

Impact of GST 2.0 on the Cement Industry

The cut in GST on cement from 28% to 18% is a significant step. As cement makes up around 15–20% of overall construction expenses, this 10% reduction directly brings down the cost of building homes and infrastructure. The move is expected to give a boost to the affordable housing sector, which previously faced pressure from high input costs. Although the higher rate has been removed, businesses continue to use GSTR-3B for regular filings to claim eligible Input Tax Credits (ITC).

GST trends and the real estate industry

The move to a simplified two-slab GST structure of 5% and 18% has reduced much of the complexity in real estate accounting. By lowering GST on key materials such as paints, tiles, and cement to 18%, the government has encouraged developers to pass on cost savings to homebuyers. At the same time, the 5% GST rate on under-construction residential properties, without input tax credit, continues to apply to non-affordable housing to help keep the final price stable for buyers.

What is the GST rate on sand?

The GST rate on sand in India is set at 5%. This relatively low rate aims to keep the costs of basic construction materials affordable, especially for small-scale and rural construction projects. The tax applies to both natural sand and manufactured sand, ensuring uniformity across different types of the material. This rate is crucial for the construction sector as sand is a fundamental component in concrete and other building materials. Keeping the GST on sand low helps manage overall construction costs and supports infrastructure development. If you're registering for GST, you will need to provide the gst registration documents as part of the process.

What is the GST rate on Bricks and Tiles?

As per the new notification effective 22nd September 2025, GST on common construction materials has been reduced to support the "Housing for All" initiative:

  • Building Bricks (Clay, Fly Ash): 5% (down from 12%)
  • Roofing/Earthen Tiles: 5% (down from 12%)
  • Cement/Concrete Blocks: 12% (previously 18%)

Conclusion

The updated GST rates on construction materials significantly ease cost pressures for both builders and homebuyers. Reduced taxes on cement, bricks, and tiles make housing more affordable, simplify compliance, and promote growth in the real estate sector. With clearer slabs and predictable input costs, developers can plan projects more efficiently while supporting the government’s long-term housing and infrastructure goals.

Frequently asked questions

What is the GST rate on cement?

Effective 22 September 2025, the GST on cement has been reduced from 28% to 18%. This major reform under "GST 2.0" reclassifies cement as a standard construction material, easing the tax burden for residential and infrastructure projects. The 18% rate applies to all types of cement uniformly.

How to calculate cement GST bills?

To compute your cement GST under the revised 2025 rates, apply the 18% GST to the base price:

  • Base Price: Rs. 10,000
  • GST (18%): Rs. 1,800 (Rs. 10,000 × 18%)
  • Total Amount Payable: Rs. 11,800

Under the previous 28% rate, the total would have been Rs. 12,800, meaning this reduction saves Rs. 1,000 for every Rs. 10,000 spent on cement.

Is GST applicable on cement bricks?

Yes, GST is applicable to cement bricks, and the rate has been rationalised to 12% (6% CGST + 6% SGST) for most building bricks and fly ash blocks according to the latest 2025 notifications. While regular cement attracts an 18% GST, these pre-cast cement products fall under a lower slab to support affordable housing. It is essential to verify the relevant HSN code (for example, 6810 for cement bricks and 6815 for fly ash blocks) to apply the correct tax.
