GST Impact on Construction Cost
Materials like cement and paint attract a high 28% GST, which increases the base cost of construction. Meanwhile, essentials like bricks, sand, and fly ash are taxed at just 5%, keeping them affordable.
Items taxed at 18% like steel, tiles, wiring, and bathroom fittings fall in the mid-range, forming a large share of construction expenditure.
Knowing these slab-wise differences helps builders and homebuyers make smarter procurement choices.

Input Tax Credit for Builders
Builders and contractors registered under GST can claim Input Tax Credit (ITC) on the GST paid for construction materials.
However, if the construction is for personal use or for selling as completed property, ITC is not allowed under certain rules. For under-construction properties, developers can claim ITC only under the old 12% GST regime (if opted before April 2019).
So, the benefit of ITC depends on:
- GST rate opted by builder
- Type of construction (residential vs commercial)
- Stage of completion and sale
