How this is worked out

The agreement value is not the base price. It is the base price plus PLC, floor rise, car park and club membership — so every statutory percentage is applied to a larger number than the one in the advertisement.

Worked from the data: on the median listed unit the agreement value is ₹1.13 Cr, giving ₹5.7 L of GST, ₹7.9 L of stamp duty and ₹4.5 L of registration.

How the Tamil Nadu rate is made up: Tamil Nadu — 7% duty with registration at 4%, the heaviest combination in this catalogue.

⚠️ Verify before transacting. These are the rates each listing records, derived from the listing's own figures as at 5 Aug 2026, and they are illustrative prototype figures. Real duty varies with the buyer's gender, the value slab, whether the address sits inside a municipal corporation and the state budget of the year. This is not tax or legal advice.
