GST on Under-Construction Property in India (2026)

Property GST hinges on one thing: whether construction is complete. An under-construction home carries GST; a ready-to-move flat with a completion certificate does not. And within under-construction, affordable and other homes have different rates. Here's the 2026 picture for buyers and builders.

Quick answer: affordable under-construction home = 1% (no ITC); other under-construction home = 5% (no ITC); commercial under-construction = 12% (with ITC); ready-to-move (completion certificate) = no GST.

Property GST at a glance

Why ready-to-move is GST-free

GST is a tax on the supply of under-construction services. Once a project has its completion certificate (or first occupation), a sale is treated as a transfer of immovable property, which is outside GST — only stamp duty and registration apply. That's why a ready-to-move flat has no GST while an under-construction one does.

The no-ITC trade-off on homes

The 1% and 5% residential rates come without input tax credit for the builder — a lower headline rate in exchange for no credit on cement, steel and inputs. Commercial under-construction at 12% allows ITC. The developer's inability to claim ITC on 1%/5% homes is part of why those rates are low.
