If you own property in Bengaluru, the civic body you have dealt with your whole adult life no longer exists. BBMP stopped governing on 2 September 2025 and was replaced by the Greater Bengaluru Authority, with the city reorganised into five separate corporations. Most guides you will find online have not caught up. Here is what actually changed, and the short answer on what it means for your paperwork is: less than you fear.

What actually happened

The Karnataka legislature passed the Greater Bengaluru Governance Act, 2024 in March 2025. Under it, the Greater Bengaluru Authority came into existence on 15 May 2025 as the apex civic body for the city, and became fully operational on 2 September 2025. On that date the Bruhat Bengaluru Mahanagara Palike — BBMP — ceased its governance functions after eighteen years.

The reasoning was straightforward enough. BBMP administered a city that had roughly tripled in population since the body was formed in 2007, across an area that kept absorbing surrounding land. One corporation covering all of it had become unwieldy. The Act split the city into smaller corporations under a single coordinating authority.

What this does not change

Start here, because it is the question people actually have, and the answer is reassuring.

Your SAS property tax ID is the same. Your existing Khata remains valid — a certificate issued under BBMP was not invalidated on 2 September 2025. The e-Aasthi portal, where Khata and property records live, carried across unchanged and is still run by the Government of Karnataka through the Karnataka Municipal Data Society. Property tax continues on the same system.

No document you hold needs reissuing because of the transition. If somebody tells you otherwise and offers to handle it for a fee, that is a good moment to stop the conversation.

What does change

Three things, in rough order of how much they will affect you.

• The name on newly issued documents. Certificates and approvals issued now come from the corporation with jurisdiction, under the GBA, rather than from BBMP.
• Which office handles a problem. A dispute, an approval or a correction now goes to your corporation. For most owners this is the single practical difference, and it is worth establishing which one you are in before you need to know.
• Local administration over time. Five corporations means five sets of budgets, priorities and works programmes. Over years, that is likely to produce real differences in how fast things get done in different parts of the city.

Worth being honest about the last one, because it cuts both ways. Smaller units can be more responsive and more accountable. They can also be less well funded. Which of those a given corporation turns out to be is not something anybody can tell you yet, and anyone who claims otherwise is guessing.

The boundary question

This is the loose end, and it deserves a straight answer rather than a confident one.

As of May 2025 the GBA had not officially demarcated the new municipal corporation boundaries, with draft notifications issued later in 2025. For most properties in the established parts of the city, which corporation you fall under is obvious from geography. For properties near a boundary — and Bengaluru has a lot of recently absorbed periphery — it is worth confirming rather than assuming.

If you are buying on the edge of the city, ask the question directly during diligence. It affects which office you will deal with for the Khata transfer after registration, and knowing it in advance saves a wasted trip.

This matters most in exactly the places Bengaluru has been growing fastest. The northern corridor around Devanahalli and Bagalur, the eastern stretch past Whitefield, and the southern periphery beyond Electronic City are all areas where the city boundary has moved within living memory. A project like Prestige Marigold Phase 2 at Yelahanka sits in precisely that kind of location — well inside the city in practice, on ground that was periphery not long ago.

There is no cause for alarm in any of this. Jurisdiction is an administrative question, not a title question, and it does not affect who owns the property or what it is worth. It affects which counter you queue at. But knowing the answer before you need it is free, and finding out on the day is not.

What it means if you are buying

For a buyer the transition changes process, not risk. The documents to collect are the same ones as before.

1. e-Khata — and check whether it is a draft or a final certificate, because only the final is accepted at registration. Our e-Khata sample walkthrough shows exactly what to look at.
2. Property tax paid up to date. Arrears transfer to you and will block a Khata transfer.
3. The right Khata type. A-Khata and B-Khata still mean what they meant, and the difference still decides whether a bank will lend — we cover it in A-Khata, B-Khata and e-Khata.
4. Which corporation the property sits in, so you know where the Khata transfer goes after registration.

And budget properly for the statutory side, which changed separately and more expensively in 2025: stamp duty, registration and cess now come to roughly 7.5% of value on a flat above ₹45 lakh, because the registration charge doubled to 2% on 31 August 2025. We show the full working in stamp duty and registration charges in Bangalore.

That is the genuinely expensive change of 2025. The GBA transition is administrative. The registration increase costs you a lakh on a crore.

It is worth separating those two clearly, because they happened within days of each other and get muddled together in conversation. The registration charge rose on 31 August 2025. The GBA took over on 2 September 2025. One of those changed what you pay. The other changed who you pay it to. Only the first one should affect your budget.

Why the city was split at all

The reorganisation was not sudden, and understanding the reasoning helps you read what happens next.

BBMP was formed in 2007 by merging the old city corporation with surrounding municipalities and villages. It inherited an area far larger than the body that preceded it, and then spent eighteen years administering a city that kept growing outward faster than its systems could absorb. One corporation handled everything from the dense old core to farmland that became apartment corridors within a decade.

The case for splitting it was that a single administration covering that range of conditions ends up serving none of them well. Smaller corporations can set priorities that suit their own areas, and a coordinating authority above them handles what has to be city-wide — the things that make no sense to fragment, like major infrastructure.

The case against was that fragmentation can concentrate money where the tax base already is, and that a poorer corporation stays poorer. Both arguments are reasonable and neither has been settled by events yet, because the corporations have barely begun operating independently.

For a property owner the honest position is that it is too early to price this into a buying decision. If you are choosing between two areas, choose on the things you can actually verify — commute, infrastructure that already exists, project approvals, the Khata — not on a guess about which corporation will be better run. That guess will be available as evidence in a few years. It is not available now.

Where new projects sit in this

New launches carry approvals from whichever authority had jurisdiction when they were granted, so a project approved under BBMP before September 2025 is not affected by the change — the approvals stand.

What you should still check, exactly as before, is the RERA registration on the Karnataka RERA portal for the specific phase you are buying into, and the occupancy certificate for anything already completed. Those are the two documents that tell you whether a project is what it claims to be, and neither was touched by the reorganisation.

For an under-construction purchase, the Khata comes after completion and assessment, so there is nothing to check yet on that front. For a ready flat — something like Prestige Sunrise Park in Electronic City, where handover has already happened — the Khata exists and should be produced before you pay an advance, not after.
