How to Convert B Khata to A Khata in Bangalore


If you want to know how to convert B Khata to A Khata, eligible property owners in Bengaluru can apply through the designated municipal B-to-A Khata process, submit the required property and ownership records, complete Aadhaar-based verification and pay the applicable conversion charges. As of September 2026, the temporary 2% concession that ran until August 23, 2026 has ended, so the standard charge is applicable to new applications.
How to Convert B Khata to A Khata Online?
You can apply for B Khata to A Khata conversion online through the designated B-to-A Khata portal. The process starts with property and owner verification, followed by document scrutiny and a physical site inspection before the main conversion charge is demanded.
Step 1: Log in to the B-to-A Khata portal
Open the official B-to-A Khata in BBMP Portal i.e, https://bbmp.karnataka.gov.in/BtoAKhata/ and log in using the owner's details and the required Aadhaar authentication.
Keep the property documents ready before starting the application so the details entered online match the registered records.
Step 2: Enter and verify property details
Enter the required property information and check the details displayed by the portal.
Verify the:
Property ID/PID
Owner name
Property location
Site dimensions
Existing B Khata details
Ward and other property details
If the portal information doesn't match your registered documents, resolve the mismatch before submitting the application.
Step 3: Upload the required documents
Upload the documents requested for your property, such as the registered sale deed, B Khata record, latest property-tax receipt, Aadhaar details and applicable land or building documents.
Make sure the uploaded copies are clear and the information matches the details entered in the application.
Step 4: Pay the ₹500 application fee
The ₹500 application/registration fee is paid at the application stage, before the property goes through official scrutiny. The fee is separate from the main B Khata to A Khata conversion charge. The Indian Express reported that applicants are required to pay ₹500 when registering for the B-to-A Khata process.
After payment, save the application acknowledgement and payment receipt for future reference.
Step 5: Complete document scrutiny and site inspection
After the application is submitted, the property goes through document scrutiny and physical site verification.
A Revenue Inspector and Tax Inspector can examine the submitted records and inspect the property. The verification can cover the property's location, site details and other conditions relevant to the application.
This stage happens before the main conversion charge is paid.
Step 6: Pay the applicable conversion charge
Once the scrutiny and site verification are completed and the application is found eligible, the authority generates the applicable payment demand.
As of September 2026, the standard conversion charge is 5% of the property's applicable government guidance value. The temporary 2% concession ended on August 23, 2026.
For example, if the applicable guidance value is ₹60 lakh:
₹60,00,000 × 5% = ₹3,00,000
This ₹3 lakh is the conversion charge in this example and is separate from the ₹500 application fee.
Step 7: Receive the A Khata approval
After the demanded conversion charge is paid and the required verification is complete, the application moves towards approval.
Once approved, the property's A Khata/e-Khata record can be generated through the applicable municipal system. The payment of the conversion charge therefore comes after property scrutiny and site inspection, not before them.

Which Properties Can Be Converted from B Khata to A Khata?
A B Khata property can be considered for A Khata conversion if it meets the land-use, size, Khata, access and planning conditions prescribed under the current Karnataka rules. The eligibility also depends on when the B Khata was issued and whether the property falls within an excluded land category.
For an urban property, check these conditions before applying:
Existing B Khata: The property should have a B Khata issued on or before September 10, 2024, or meet the alternative eligibility provision for properties that existed before the cut-off date.
Property size: The current state-wide mechanism covers plots, sites or land measuring up to 1,000 sq. m.
Non-agricultural use: The property must already have been put to the proposed non-agricultural use, subject to the applicable land-use rules.
Permitted use: The proposed use must be allowed under the applicable Master Plan, zoning rules or other town-planning provisions.
Property access: The property must have the required road/access arrangement. Private-road situations may require the road to be recognised as a public road under the applicable process.
Certain properties are specifically excluded, including government land, B-Kharab land, forest land, gomal land, tanks or tank beds, rajakaluves, nalas, roads, road margins and land reserved for public purposes.
So, having a B Khata certificate alone doesn't guarantee conversion. Check the property's Khata date, land status, size, permitted use and road access before submitting the application.
