A Bengaluru buyer who budgeted carefully in 2023 comes back to the market in 2026 and gets a small shock at the sub registrar's counter. The registration fee they remembered as one percent is now two, doubling that line of the bill, while the stamp duty slab still climbs with the value of the flat. Neither change is hidden, but both are easy to miss if you rely on an old rule of thumb. For a purchase this size, the safest habit is to price the government charges from the current rates, not from what a friend paid a few years ago, because these numbers have moved.

The short answer. In Karnataka, stamp duty on a residential sale follows a slab: 2 percent below 20 lakh rupees, 3 percent between 20 and 45 lakh, and 5 percent above 45 lakh, all charged on the higher of your price or the government guidance value. Registration is now 2 percent, raised from the long standing 1 percent, so a flat above 45 lakh in Bengaluru carries roughly 7 percent in combined stamp duty and registration, before a small cess and surcharge on the stamp duty. The trade off to plan for is that these are your own funds at registration, not something the home loan covers.

What are the stamp duty slabs in Karnataka?

Stamp duty rises in steps with the value of the property. As ClearTax sets out for Karnataka, the rate is 2 percent for property valued below 20 lakh rupees, 3 percent between 20 and 45 lakh, and 5 percent above 45 lakh, and these rates are the same across the state and do not change with the gender of the owner. Most Bengaluru apartments sit in the top slab, so a buyer here is usually working with the 5 percent figure.

The slab is applied to the whole value once your property falls into a band, so a flat above 45 lakh is charged 5 percent on its full value. Knowing which slab you are in is the first step, because it fixes the largest single charge in your closing. For most city flats that means starting your budget from 5 percent stamp duty and building the rest on top of it. That single rate is the backbone of the closing cost, so it is the first number to fix before adding anything else. Buyers in the lower slabs, for a compact home or a plot in an outer area, benefit from the 2 or 3 percent rate, but should still confirm which band their value falls into.

What has changed with registration charges?

The registration fee in Karnataka is now 2 percent of the property value, doubled from the 1 percent that applied for many years. ClearTax confirms the registration charge is 2 percent for the sale of all kinds of properties in the state, so a buyer budgeting from an older 1 percent figure will be short by a full percentage point of the property value. On a flat above 45 lakh, that difference alone can run into a meaningful sum.

This is the single change most likely to catch a returning buyer off guard, which is why it deserves a line of its own in your plan. Registration is charged on the same value as stamp duty, the higher of your price or the guidance value, so the two move together. Update your mental arithmetic to 2 percent registration, and the rest of your budget will hold. It is worth keeping a copy of the current fee schedule, so that if anyone quotes you the old rate you can point to the change rather than argue from memory.

What is the total you should budget?

For a flat above 45 lakh in Bengaluru, budget roughly 7 percent of the property value for stamp duty and registration together. That is 5 percent stamp duty plus 2 percent registration, before a small cess and surcharge that are levied on the stamp duty in urban areas and nudge the effective stamp duty a little above 5 percent. Because the cess and surcharge are modest and can vary, confirm the exact combined figure on the state's Kaveri portal or with the sub registrar rather than assuming a single number. The portal reflects the current rates and is the most reliable place to pin the final figure.

Treat this 7 percent or so as cash you arrange yourself. Home loans are sized against the property value and do not usually fund the stamp duty and registration, so these charges land on the buyer at the point of registration. A buyer who has stretched to the down payment and forgotten this line is the one scrambling at the counter, so build the full amount into your plan from the outset. Setting the money aside early also means the registration date can be booked without a last minute scramble to arrange funds, which keeps the whole transaction on schedule.

How do the charges look across values?

The slab structure means your rate depends on where your flat sits. The table below shows the pattern for a Karnataka residential purchase.

The last row is the one buyers most often overlook. Both stamp duty and registration are charged on the higher of your agreed price or the government guidance value, so a low figure in the agreement does not reduce the bill if the guidance value is higher. Look up the guidance value for your exact property before you finalise the budget, because that number, not just your price, sets what you pay. That single check protects the accuracy of your whole budget.

Why is the value basis so important?

Because the government values the property independently, and charges on the higher figure. If the guidance value for your flat is above your negotiated price, both stamp duty and registration are computed on that higher guidance value, so the saving you thought you had negotiated does not carry into the duty. This is by design, to prevent under declaration, and it applies uniformly. The department publishes these guidance values, and they are revised from time to time, so a value that was accurate a year ago may have moved.

The practical response is to treat the guidance value as the floor of your cost planning. Check it early, compare it with your price, and compute your 7 percent or so on whichever is higher. Doing this before you commit turns the government charges from a nasty surprise into a known, fixed line that you have already provided for in full. This one habit, checking the guidance value first, prevents the most common budgeting error buyers make on a Karnataka purchase.

How does this fit your other Bengaluru costs?

Stamp duty and registration sit within a wider set of closing costs and taxes. The same higher of price or guidance value that sets your duty also sets the base for your withholding tax, which we cover in our guide to TDS on a property purchase under Section 194-IA, so getting the value right serves both calculations at once. Aligning them keeps your total closing outflow accurate.

These charges also sit alongside your financing, and it helps to see the whole picture together. Our guide to how your home loan EMI works at the current repo rate covers the monthly commitment, while the stamp duty and registration are one time costs you fund yourself. If you are weighing a specific project, a registered development such as Adarsh Savana comes with clear value records, which makes computing these charges straightforward.

What should a Bengaluru buyer do?

Price the government charges from current rates before you commit:

1. Identify your stamp duty slab from the property value, usually 5 percent in the city.
2. Use the current 2 percent registration figure, not the older 1 percent.
3. Look up the guidance value for your exact flat and compare it with your price.
4. Compute stamp duty and registration on whichever of the two is higher.
5. Add a small allowance for the cess and surcharge on the stamp duty.
6. Confirm the exact combined figure on the Kaveri portal or with the sub registrar.
7. Arrange the full amount as your own funds, since the loan does not cover it.

Frequently asked questions

What are the stamp duty rates in Karnataka?

Stamp duty in Karnataka follows a slab: 2 percent for property below 20 lakh rupees, 3 percent between 20 and 45 lakh, and 5 percent above 45 lakh. The rate applies to the whole value once your flat falls into a band, and it is the same across the state. Most Bengaluru apartments sit in the top slab.

Has the registration charge in Karnataka changed?

Yes. The registration fee is now 2 percent of the property value, doubled from the old 1 percent. A buyer budgeting from the old figure will be short by a full percentage point of the value. Registration is charged on the same base as stamp duty, the higher of your price or the guidance value.

How much should I budget in total for a Bengaluru flat?

For a flat above 45 lakh, budget roughly 7 percent of the value, being 5 percent stamp duty plus 2 percent registration, before a small cess and surcharge on the stamp duty. Confirm the exact combined figure on the Kaveri portal or with the sub registrar. These are your own funds at registration.

Are the charges based on my price or the guidance value?

They are based on whichever is higher, your agreed price or the government guidance value for the property. If the guidance value exceeds your price, both stamp duty and registration are computed on that higher figure. This is why you should look up the guidance value for your exact flat before finalising your budget.
