Delhi NCR [India], September 5: The GST Council has rationalised tax rates into a simplified two-slab structure of 5% and 18%. Among the most impactful changes is the reduction of GST on cement from 28% to 18%, a move expected to significantly lower project costs and drive growth in real estate. The Council has also reduced GST on marble and travertine blocks, granite blocks, sand-lime bricks, and stone inlay work from 12% to 5%, further easing input costs for developers.
