In September 2025, a couple buying a two-bedroom flat off Sarjapur Road walked into a Bengaluru sub-registrar office expecting to hand over a franked sale deed, and were told to generate a Kaveri challan instead. The rules had shifted under their feet twice that year, first when the state notified new digital e-stamp rules, then again when the registration fee doubled. Knowing the right mode of stamp duty payment in Karnataka is now as important as knowing the rate.

The short answer. A Bengaluru buyer can pay stamp duty four ways: e-stamping through SHCIL, franking at an authorised bank, physical stamp paper, or an e-challan generated inside Kaveri 2.0. For a registered sale deed the duty is 5% above Rs 45 lakh, 3% between Rs 20 lakh and Rs 45 lakh, and 2% up to Rs 20 lakh, plus a registration fee of 2%. The trade-off: the Kaveri challan and e-stamp routes are fastest and are now the state's preferred rails, while franking is being phased down and physical stamp paper is fading out.

Karnataka notified the Karnataka Stamp (Digital e-Stamp) Rules, 2025 on 7 August 2025 and doubled the property registration fee from 1% to 2% effective 31 August 2025, according to the Department of Stamps and Registration. That single quarter reshaped how money actually moves when you register a property in Bengaluru.

How do you actually pay stamp duty in Karnataka in 2026?

You pay through one of four instruments, and for a property sale in Bengaluru the practical winner is almost always an electronic payment tied to the Kaveri Online Services portal. The Department of Stamps and Registration recognises e-stamping, franking, physical stamp paper and electronic payment, and the last two years have steadily pushed transactions toward the digital rails. When you book a slot on Kaveri 2.0, the portal calculates the duty on the higher of your consideration or the guidance value, then lets you pay by net banking, UPI, debit card or credit card and issues a challan you carry into the sub-registrar office.

The key mental model is that stamp duty is one thing and the instrument you use to prove you paid it is another. Franking, e-stamp certificates and challans are all just proof of the same underlying tax. What changes between them is speed, where they are accepted, and how quickly the mode is being retired.

What does each payment mode mean, and where is it accepted?

Each mode is a different way of stamping the same duty, and all four are accepted at a Bengaluru sub-registrar office when done correctly, but they are not equally convenient. E-stamping produces a computer-generated certificate carrying a Unique Identification Number that anyone can verify online, which is why banks and buyers trust it for high-value deeds. Franking is an ink impression a bank or authorised collection centre stamps onto the first page of your document after you pay the duty to them, historically used for smaller instruments like rental and sale agreements. Physical stamp paper is the old non-judicial paper bought from a licensed vendor, and it is the mode the department is actively moving away from.

The fourth mode, an e-challan or e-payment through Kaveri, is not a stamp at all but a treasury receipt proving the duty hit the government account. For a registered sale deed in Bengaluru this challan route, combined with an e-stamp, is what most sub-registrar offices now expect.

Why is franking being phased down in Bengaluru?

Franking is being phased down because it depends on physical machines at banks and collection centres that the state is replacing with a fully digital, treasury-linked system. The Karnataka Stamp (Digital e-Stamp) Rules, 2025 were framed to move stamping onto an integrated online platform with direct treasury payment, template-based deed writing and Aadhaar-based authentication of the parties, as summarised in this note on the Digital e-Stamp Rules. Several reports note the new rules are designed to remove the SHCIL service charge and route money straight to the treasury, which reduces the role of intermediaries that franking and third-party e-stamping relied on.

For a Bengaluru buyer this means franking still works today for many agreements, but it is the mode most likely to disappear or be capped first. Banks already frank only up to certain document values, and franking availability varies branch to branch. Compared with a year ago, when franking a sale agreement was routine, the momentum has clearly moved to e-stamp certificates and Kaveri challans. That is the honest trade-off: franking is familiar and often available at your own bank, but you are choosing the mode with the shortest remaining runway.

How does the Kaveri 2.0 challan route work step by step?

The Kaveri 2.0 route works by calculating your duty inside the portal, collecting payment digitally, and issuing a challan you present at registration. You log in to the Kaveri Online Services portal, choose the document registration service, and enter the property and consideration details. The system compares your sale value against the applicable guidance value and computes stamp duty plus the registration fee on whichever is higher. You then pay online and download the challan and, where required, an e-stamp certificate.

The comparison table below shows how the four modes stack up for a typical Bengaluru sale deed. Note that only one of these, physical stamp paper, is genuinely on its way out, while franking sits in a shrinking middle ground.

What will the stamp duty and registration actually cost you?

Your headline cost is the stamp duty slab plus the registration fee, and both are set by the value of the property, not the mode you choose. For a sale deed the stamp duty is 5% for property valued above Rs 45 lakh, 3% for value between Rs 20 lakh and Rs 45 lakh, and 2% for value up to Rs 20 lakh. On top of that sits a registration fee that the Karnataka government doubled from 1% to 2% with effect from 31 August 2025, the first such revision in over two decades.

In Bengaluru, cess and surcharge components push the effective stamp incidence above the base 5% for higher-value flats, and several outlets estimate the combined outgo at roughly 7.6% of value once the 2% registration fee is added. The mode of payment does not change any of this. Whether you frank, e-stamp or pay by Kaveri challan, the arithmetic on the guidance value is identical, which is exactly why choosing a mode should come down to convenience and acceptance rather than cost. For a full breakdown of the slabs and the recent fee revision, see our explainer on Karnataka stamp duty and registration charges.

Which mode should a Bengaluru buyer choose?

For a registered sale deed, choose the Kaveri challan combined with an e-stamp, because that is the combination Bengaluru sub-registrar offices process most smoothly and verify instantly. It leaves a clean digital trail, the UIN on an e-stamp can be checked online, and you avoid depending on a bank branch having a working franking machine or the right stamp paper denomination in stock. Reserve franking for low-value agreements where your bank offers it and you want a one-window option, and treat physical stamp paper as a last resort only when nothing else is available.

The honest counterpoint is that digital does not mean frictionless. Kaveri 2.0 has had slot-availability and server-load complaints, and a failed online payment can leave your money in limbo for days while you chase a refund or re-challan. If a deadline is tight and the portal is down, a franked or e-stamped instrument bought in person can still be the pragmatic choice. Pick the mode that will actually clear before your registration appointment, not just the one that is theoretically most modern.

What paperwork and pitfalls should you watch for?

The paperwork you carry to registration matters as much as the payment mode, because a mismatch between the stamped value and the guidance value can stall the whole appointment. Work through this checklist before you pay.

1. Confirm the guidance value for your exact survey number and locality, since duty is charged on the higher of guidance value or sale price.
2. Decide your mode early, because e-stamp and Kaveri challan generation can be done ahead of the appointment while franking needs a bank visit.
3. Match the name and property details on the stamp instrument exactly to the sale deed, as any spelling mismatch can force a re-issue.
4. Keep the challan reference or e-stamp UIN handy and verify it online before you travel to the sub-registrar office.
5. Budget for the 2% registration fee separately from stamp duty, so a payment failure on one does not block the other.
6. Save screenshots and transaction IDs for every online payment in case a Kaveri transaction fails midway and needs a refund.
7. Ask whether your instrument is within any franking value cap if you choose that mode, to avoid being turned away at registration.

Get these right and the mode becomes a detail. Get the guidance value or the name matching wrong and even a perfect e-stamp will not save the appointment.

Can I pay Karnataka stamp duty entirely online?

Yes. Through the Kaveri Online Services portal you can calculate the duty, pay stamp duty and the 2% registration fee by net banking, UPI or card, and generate a challan and e-stamp before your registration slot. You still attend the sub-registrar office in person for biometric verification and signing of the deed.

Is franking still valid in Bengaluru in 2026?

Franking is still accepted for many agreements, but it is being phased down as Karnataka moves to a fully digital, treasury-linked stamping system under the Digital e-Stamp Rules, 2025. Banks apply value caps and machine availability varies, so for a high-value sale deed an e-stamp or Kaveri challan is the safer choice.

What is the difference between an e-stamp and a Kaveri challan?

An e-stamp is a certificate carrying a Unique Identification Number that proves stamp duty was paid, verifiable online. A Kaveri challan is a treasury receipt showing the payment reached the government account. For a Bengaluru sale deed you typically use both together, the challan for payment proof and the e-stamp as the stamped instrument.

Did Karnataka registration charges really go up?

Yes. The Karnataka government doubled the property registration fee from 1% to 2% of value with effect from 31 August 2025, the first revision in over two decades. This is separate from stamp duty and applies regardless of whether you pay by e-stamp, franking or Kaveri challan, so budget for it as a distinct line item.
