Guide — GST on Property & Works
The GST on property calculator below follows standard Indian construction practice and the relevant IS-code conventions. Enter the site dimensions exactly as measured, press Calculate Now, then refine the quantities line by line in the live sheet before you export.
GST applies only to under-construction property. Once the occupancy certificate is issued, a sale is treated as an immovable property transaction and attracts stamp duty but no GST.
Since April 2019 residential projects pay 1% on affordable housing and 5% on other residential units, both without input tax credit. Commercial construction and pure works contracts remain at 18% with ITC available.
The affordable-housing threshold is a carpet area of 60 m² in metros or 90 m² elsewhere, with a value cap of ₹45 lakh. Missing either limit moves the whole unit to the 5% slab.
Treat every output as an indicative pre-tender estimate. Site conditions, wastage allowances, specification changes and local market rates all move the final figure, so validate against your drawings and approved rate analysis before procurement.

About the GST on Property & Works
This tool is built for site engineers, quantity surveyors, contractors and property investors who need dependable numbers fast. Every input is reactive — changing a single field instantly recomputes the full output set, so you can run sensitivity checks on dimensions, grades and rates before committing to an estimate.
Keep unit consistency in mind: metric inputs (metres, square metres, cubic metres) produce metric outputs, with imperial and Indian trade units shown alongside where they are commonly used on site.
