What are the statutory costs?
Stamp duty is 5 percent on land, commercial property and resale flats, at every price point. The lower slabs, 2 percent up to 20 lakh and 3 percent from 20 to 45 lakh, apply only to the first sale of a flat by the builder under Article 20(2A) of the Karnataka Stamp Act. Cess and surcharge are added on the duty amount. Registration is 2 percent of value, uncapped, for documents executed on or after 31 August 2025. Everything is charged on the higher of your sale value or the guidance value.
