Two charges surprise buyers more than any others, and both arrive at the end of a purchase. Stamp duty and registration are not developer fees and they are not optional; they are what makes a sale deed enforceable and what puts your name on the public record. This article explains the concepts in general terms and points to where the current numbers should be confirmed. It belongs to the wider guide to buying an apartment in Bangalore.
What stamp duty is
A sale deed is a legal instrument, and Indian law requires instruments of this kind to be stamped before they can be relied on. Stamp duty is the state tax that pays for that stamp. Pay the prescribed amount and the deed is admissible; treat it as a formality and the document's validity is at risk. The duty is levied by the state, so the amount depends on Karnataka's rules at the time of execution rather than on anything the developer decides.
What registration means
Registration is the separate step of taking the executed deed to the sub-registrar's office and having it recorded. It is what converts a private agreement between two parties into a public record of ownership. Registration carries its own fee, and it produces the registered deed that you will keep and eventually pass on when you sell. Stamp duty and registration are often spoken of together because they happen at the same appointment, but they are two distinct charges for two distinct purposes.
Who pays, and when
In practice the buyer bears both, and both fall due around the execution and registration of the sale deed rather than at the time of booking or allotment. That timing matters for planning, because the money sits outside the loan alongside the other one-time charges on the cost sheet. Buyers who fund only the unit price and the down payment often find themselves short at the final stage.
| Charge | What it covers | Who normally pays | Where it is confirmed |
|---|---|---|---|
| Stamp duty | The state tax that stamps the sale deed | The buyer | The developer's cost sheet and the sub-registrar |
| Registration fee | Recording the deed and issuing the registered copy | The buyer | The sub-registrar's office |
| GST | Tax on the sale of an under-construction home | The buyer, where applicable | The cost sheet |
| One-time project charges | Clubhouse membership, infrastructure, corpus and similar | The buyer | The cost sheet for the specific unit |
The final column is the important one. Nothing in this article should be read as a current rate; rates and slabbing change, and the only figures you should rely on are the ones on your cost sheet and the ones the sub-registrar applies on the day.
Why the current rates must be confirmed
Karnataka revises stamp duty and registration charges from time to time, and exemptions or concessions can apply depending on the transaction. Two buyers completing similar purchases in different months can therefore pay different amounts for the same reason. That is why this article deliberately avoids quoting a percentage. Ask the developer for a cost sheet that shows the stamp duty and registration figures it expects, and confirm them with the sub-registrar's office or a qualified professional before you budget.
Where these charges sit in the purchase
Stamp duty and registration arrive at the registration stage, after verification, financing and the agreement for sale. If you are working through the full sequence, place them beside the home loan process, because the loan will not usually cover them, and beside the price guide to see how one project presents its figures. A caution worth repeating: at Lakeside Residences the indicative starting value excludes GST and several one-time charges, so the all-in number is meaningfully above the headline price.
