A buyer in Bengaluru who signed an agreement to sell for a flat in 2026, with the keys handed over so he could start interiors before the sale deed, was surprised to learn the agreement itself attracted stamp duty at nearly the same rate as a full sale. Another buyer, who signed a similar agreement but took no possession, paid only a small duty. The difference between the two came down to a single factor that most buyers overlook: whether possession changed hands. In Karnataka, that one fact reshapes both the stamp duty on an agreement to sell and whether it must be registered.

The short answer. Under the Karnataka Stamp Act, an agreement to sell that delivers or agrees to deliver possession before the sale deed is stamped at the same rate as a conveyance on the property's market value, while an agreement without possession attracts a much smaller, nominal duty. Crucially, duty already paid on the agreement is adjusted against the duty on the later sale deed between the same parties, so you do not pay full duty twice. The trade-off is that taking early possession under an agreement pulls the higher duty forward, and makes the agreement compulsorily registrable, so early access has a cost and a paperwork consequence.

The anchor rule for a Bengaluru buyer in 2026 is possession. Because stamp rates were revised by the Karnataka Stamp Amendment Act that took effect in early 2024, confirm the exact current figures with the Department of Stamps and Registration or on Kaveri, and read this guide for the structure rather than a specific percentage. Sale agreement stamp duty in Karnataka therefore turns on whether you take possession.

Does an agreement to sell attract stamp duty in Karnataka?

Yes, and how much depends on whether possession is delivered under it. The Karnataka Stamp Act treats an agreement to sell in which possession is delivered, or agreed to be delivered, before the conveyance as attracting the same duty as a conveyance on the market value of the property. An agreement to sell where possession is not delivered attracts only a nominal duty calculated on the consideration or market value. This is a deliberate design: an agreement that hands over possession looks economically like a sale, so it is taxed like one, while an agreement that merely records a promise to sell in future is taxed lightly. For a buyer, the practical message is that asking for early possession is not a free convenience, it changes the tax character of the document you are signing. Our guide to the agreement to sell versus the sale deed for Bengaluru buyers explains how these two documents differ in the first place.

Why does possession change the duty so much?

Possession is the trigger because the law looks at the substance of the transaction, not just its label. When you take possession under an agreement, you begin enjoying the property as if it were yours, even though the formal conveyance has not happened, and the law taxes that transfer of practical control at the conveyance rate. When no possession passes, you hold only a contractual promise, and the duty is nominal. This is why the same document, an agreement to sell, can carry wildly different stamp duty depending on one clause about handing over keys. A buyer negotiating early access should therefore factor the higher duty into the decision, because the saving in time can be offset by bringing forward a large duty payment and creating a registrable document.

There is a cash flow angle to this as well. On a possession backed agreement, the conveyance rate duty falls due at the agreement stage rather than at the sale deed, so a buyer who takes early possession is paying a large sum earlier in the transaction than a buyer who waits. Because that duty is later adjusted against the sale deed, the total is not higher, but the timing is. For a buyer who is stretching to fund the purchase, bringing forward a big duty payment to enable early interiors work can strain the budget at exactly the wrong moment, which is another reason early possession is a decision to make deliberately rather than by default.

Is the duty on the agreement adjusted against the sale deed?

Yes, stamp duty already paid on the agreement is adjusted against the duty payable on the later sale deed between the same parties for the same property, so the amount is not charged twice. The Karnataka Stamp Act provides, in an explanation to the relevant article, that where a conveyance is later executed in pursuance of the agreement between the same parties, the duty already paid on the agreement is adjusted towards the total duty on the conveyance. So a buyer who paid conveyance rate duty on a possession backed agreement does not pay it again in full on the sale deed, the earlier payment is set off. This is an important protection, because without it, taking early possession would mean paying nearly the full duty twice. The table below sets out how the common situations play out.

Read the table as structure, not as a rate card, because the exact nominal figure was revised by amendment and should be confirmed on the official portal before you rely on a number.

Must an agreement to sell be registered in Karnataka?

An agreement to sell must be registered when possession has been or will be delivered under it, and is otherwise not compulsorily registrable. The Registration Act makes a contract for the transfer of immovable property registrable where it is coupled with delivery of possession, reflecting the same logic that governs the stamp duty. So a possession backed agreement is both stamped like a conveyance and required to be registered, while an agreement with no possession can remain unregistered without losing its basic contractual validity. Because registration practice can be updated, a buyer should confirm the current requirement with the Department of Stamps and Registration, but the governing principle is the familiar one: possession changes the obligations. Our guide to token and advance money refunds for Bengaluru buyers covers the earlier stage, before any agreement is signed.

What happens to the agreement once the sale deed is executed?

Once a proper sale deed is executed and stamped for the same property between the same parties, the agreement has largely served its purpose and merges into the sale deed. Courts have recognised that an agreement to sell, once followed by a duly executed and stamped sale deed, is not independently taxed again, because it has merged into the conveyance. For a buyer, this means the sale deed is the document that finally conveys ownership, and the agreement is the interim step that protected the deal and, where possession passed, was taxed and registered accordingly. Keeping both documents is still sensible, because the agreement records the terms the parties committed to, but the sale deed is what establishes your title. If a dispute later arises about what was promised on price, timeline or fixtures, the registered agreement is the record you fall back on, which is one more reason to make sure its terms were captured accurately before you signed it.

What should a buyer do before signing an agreement to sell?

Whether or not you plan to take early possession, work through this checklist before signing an agreement to sell in Karnataka.

1. Decide whether you actually need possession before the sale deed, because that choice drives the duty and registration.
2. Confirm the current stamp duty for an agreement with and without possession with the Department of Stamps or on Kaveri.
3. Where possession is involved, budget for conveyance rate duty on the agreement itself.
4. Confirm in writing that the duty paid on the agreement will be adjusted against the sale deed duty.
5. Register the agreement where possession is delivered, as the law requires.
6. Keep the timeline to the sale deed tight, so the interim agreement stage does not drag on.
7. Have a lawyer draft or review the agreement so the possession, payment and duty terms are clear.

Does my agreement to sell pay the same stamp duty as a sale deed?

It depends on possession. Under the Karnataka Stamp Act, if possession is handed over or agreed to be handed over before the sale deed, the agreement is stamped at the same rate as a conveyance on the property market value. If no possession is transferred, only a nominal duty applies, which you should confirm currently with the Department of Stamps and Registration.

Will I have to pay stamp duty twice, on the agreement and again on the sale deed?

No. Under the Karnataka Stamp Act, when a sale deed is later executed between the same parties for the same property, the stamp duty already paid on the agreement to sell is adjusted against the total duty payable on the sale deed. You are not charged the full sale deed duty twice for the same transaction.

Is my agreement to sell invalid if I do not register it?

Not automatically. Registration of an agreement to sell is compulsory only where possession has been or will be delivered under it. If no possession is transferred, the agreement can remain unregistered without losing its basic contractual validity, though you should verify the current registration guidance with the Department of Stamps and Registration before relying on this.

What happens to the agreement once the sale deed is signed?

Once a duly executed and stamped sale deed is in place for the same property and parties, the agreement merges into the sale deed and is not independently taxed again. The sale deed becomes the document that conveys ownership, while the agreement was the interim step, taxed and registered according to whether possession passed under it.
