A Bengaluru buyer who had budgeted carefully for a flat in early 2025 came back to close a similar purchase months later and found the registration bill had quietly doubled. On an 80 lakh flat, the registration fee alone had risen from about 80,000 to 1.6 lakh, because Karnataka revised the rate in the middle of 2025. The stamp duty had not changed, the price had barely moved, yet the cash needed on registration day jumped by nearly a lakh. For anyone buying in the city now, understanding the current slabs and the 2025 registration change is the difference between a budget that holds and one that falls short at the sub registrar office.

The short answer. Registering a sale deed in Bengaluru now costs roughly 7 percent of the property value for a home above 45 lakh: 5 percent stamp duty plus a 2 percent registration fee, with a small cess and surcharge on top. Stamp duty follows a slab, 2 percent below 20 lakh, 3 percent from 21 to 45 lakh, and 5 percent above 45 lakh, charged on the higher of your price or the guidance value. The trade off to note is the 2025 change: the registration fee doubled from 1 percent to 2 percent, so older calculators understate what you actually owe.

What will registering a flat in Bengaluru cost in 2026?

For a typical flat above 45 lakh, expect about 7 percent of the value, made up of 5 percent stamp duty and 2 percent registration fee, plus a cess and surcharge on the duty. Current 2026 rate guides confirm the stamp duty slabs and that the registration fee is now 2 percent of the property value for all property transactions. On a 60 lakh flat that is about 3 lakh in stamp duty and 1.2 lakh in registration, before the cess and surcharge that nudge the effective rate a little higher. These are statutory charges collected on the sale deed, and they sit on top of the price, brokerage and any documentation the builder charges.

Treat the total as cash you must arrange yourself. Home loans generally fund a share of the property cost and expect stamp duty and registration to come from your own pocket, so a buyer who plans only for the price and the down payment will be short at the counter. A practical approach is to set aside a little over 7 percent of the property value in advance, then refine the exact number using the official calculator once you know the guidance value for your flat.

How does the Karnataka stamp duty slab work?

Stamp duty rises with the property value across three slabs. It is 2 percent for properties below 20 lakh, 3 percent for those from 21 to 45 lakh, and 5 percent above 45 lakh, and the same rates apply across Karnataka with no concession based on the owner's gender. The table below sets out the slabs alongside the registration fee so you can see the full picture.

Most Bengaluru apartments fall into the top slab, so the 5 percent rate is the one to plan around. For example, a flat at a project such as Arvind Sylva in Kodathi priced above 45 lakh would attract the 5 percent stamp duty slab, plus the 2 percent registration fee and the cess and surcharge on the duty.

What changed in 2025 that raised my registration cost?

Karnataka doubled the registration fee from 1 percent to 2 percent in 2025. The revision, reported to have taken effect on 31 August 2025, applies to all property transactions including resale and new construction, and it materially raised the cash a buyer needs at registration. As one guide illustrated, on an 80 lakh property the registration fee alone rose from about 80,000 to 1.6 lakh after the change, with no change in the sale price.

This is why older stamp duty calculators and even recent advice can understate your bill. If a source still shows a 1 percent registration fee, it predates the revision. Always apply the current 2 percent registration fee, and confirm it on the official portal, so your budget reflects what you will actually pay rather than what buyers paid a year ago.

Is the charge based on my price or the guidance value?

It is based on whichever is higher, your agreed price or the government guidance value. Stamp duty is typically calculated on the higher of the transaction value or the guidance value notified by the government for that location. If your negotiated price is below the guidance value, the sub registrar still charges duty on the higher guidance value, so a low declared price does not reduce your bill. If your price is higher, duty is charged on your price.

Because the guidance value sets the floor, checking it early is essential to an accurate budget. Our companion guide to the e stamping and franking process in Karnataka covers how you then pay the duty once you know the figure.

What extra cess and surcharge apply?

On top of the headline stamp duty, Karnataka adds a cess and a surcharge calculated on the duty. These are smaller components than the main slab, but they raise the effective stamp duty above the flat 5 percent, which is why the true cost for a home above 45 lakh lands a little over 7 percent once registration is included. The exact cess and surcharge depend on the property location and the transaction, so the reliable way to get your precise figure is the official calculator rather than a rounded estimate. Because they are calculated on the duty rather than on the full property price, they add a modest amount rather than a large one, but they are still real cash you should include in your plan.

Do not treat a broker or builder calculator as final. The binding figures come from the Karnataka Registration Department, and the safest step is to compute the amount on the official Kaveri Online Services system before you plan your cash. For related mortgage side costs, our note on MODT and mortgage registration charges covers a charge many loan buyers overlook.

How and where do I pay and check the exact figure?

Compute and pay through the official Kaveri Online Services portal run by the Karnataka Registration Department. The portal at kaveri.karnataka.gov.in lets you look up the guidance value, calculate stamp duty, registration fee, cess and surcharge, and generate the challan. Doing this first means your total is built from official figures, not an outdated calculator, and it flags cases where the guidance value is higher than your negotiated price.

Once you have the figure, you pay the stamp duty through e stamping or the prescribed challan and book a registration slot. Keep the paid challans with your sale deed and encumbrance certificate, since you will need them for mutation, khata and any later loan step. Use the checklist below to work through the cost in order.

1. Find the guidance value for the property on Kaveri Online Services.
2. Identify your stamp duty slab from the higher of your price or the guidance value.
3. Add the 2 percent registration fee, revised up from 1 percent in 2025.
4. Add the applicable cess and surcharge on the stamp duty using the official calculator.
5. Budget the full total as cash, separate from your price and loan.
6. Pay via e stamping or the prescribed challan before your registration slot.
7. Register the sale deed and keep the paid challans with your documents.

Following these seven steps in order gives you a figure you can rely on and removes the risk of a shortfall on registration day.

What mistakes cost Bengaluru buyers money?

The most common mistake now is budgeting with the old 1 percent registration fee. After the 2025 revision to 2 percent, a buyer using last year's numbers is short by 1 percent of the property value, which is a lakh on a 1 crore flat. Others plan only for the 5 percent stamp duty and forget the cess and surcharge, and some negotiate hard on price only to find duty charged on a higher guidance value. Each of these leaves a gap between the budget and the counter.

Avoiding them comes down to one habit: build your figure on the official Kaveri calculator using the current rates, apply the higher of price or guidance value, and treat the total as fixed cash. Do that and the registration bill will match your plan rather than surprise it.

Frequently asked questions

What are the stamp duty and registration charges in Bengaluru in 2026?

For a home above 45 lakh, expect about 7 percent of the value: 5 percent stamp duty and a 2 percent registration fee, plus a cess and surcharge on the duty. Stamp duty is 2 percent below 20 lakh, 3 percent from 21 to 45 lakh, and 5 percent above 45 lakh in Karnataka.

Did Karnataka increase the registration fee?

Yes. The registration fee was revised from 1 percent to 2 percent of the property value, reported to have taken effect on 31 August 2025, and it applies to all transactions including resale and new construction. On an 80 lakh property this raised the registration fee alone from about 80,000 to 1.6 lakh.

Is stamp duty charged on my price or the guidance value?

It is charged on whichever is higher. Stamp duty is typically calculated on the higher of your transaction value or the government guidance value for that location. If your price is below the guidance value, the sub registrar charges duty on the higher guidance value, so a low declared price does not cut your bill.

Where can I calculate the exact charges?

Use the official Kaveri Online Services portal run by the Karnataka Registration Department. It lets you look up the guidance value and calculate stamp duty, the registration fee, and the cess and surcharge for your specific property, then generate the challan. Building your budget from these official figures avoids the errors that outdated calculators introduce.
