1. What Is SRO Registration?
Property registration in India is governed by the Registration Act, 1908 and is mandatory for all property transactions above ₹100 in value (Section 17). In practice, all residential property purchases must be registered to be legally valid and enforceable.
The Sub-Registrar's Office (SRO) is the government office that records the sale deed and provides an official registration number. Once registered, the transaction is entered into the public record maintained by the Kaveri Online system in Karnataka.
Registration serves several purposes:
- Creates an indefeasible legal record of ownership transfer
- Enables Khata transfer at BBMP to the new owner
- Allows the bank to create a mortgage charge on the property for home loan
- Provides legal evidence in any ownership dispute
- Required for any further sale, inheritance, or gift of the property
In Bangalore, registration is done at the SRO for the jurisdiction where the property is located. Different areas in Bangalore are under different SRO jurisdictions. The builder or seller typically knows which SRO has jurisdiction. You can also look up the SRO on the Kaveri Online portal at kaveri.karnataka.gov.in.
2. Karnataka Stamp Duty Rates 2026
Karnataka has a tiered stamp duty structure based on property value. The 5.6% rate for properties above ₹45L comprises: 5% base stamp duty + 0.5% KSFDC (Karnataka Slum Development Board) cess + 0.1% local body cess.
| Property Value | Stamp Duty | Registration Fee | Total Rate | Example |
|---|---|---|---|---|
| Up to ₹20 lakhs | 2% | 1% | 3% | ₹20L flat → ₹60,000 |
| ₹20L to ₹45L | 3% | 1% | 4% | ₹40L flat → ₹1,60,000 |
| Above ₹45L | 5.6% | 1% | 6.6% | ₹1Cr flat → ₹6,60,000 |
| Women buyers (above ₹45L) | 5.1% (0.5% concession) | 1% | 6.1% | ₹1Cr flat → ₹6,10,000 |
Note: Women buyers in Karnataka get a 0.5% concession on stamp duty (reduced to 4.5% for the base component), making the total 5.1% + 1% registration = 6.1% for properties above ₹45L. This concession applies only if the property is purchased in the woman's name or jointly with the woman as the first applicant.

3. SRO Registration Process — Step by Step
Calculate Stamp Duty
Determine the stamp duty on the higher of agreement value or guidance value. Get the guidance value from Kaveri Online by selecting the SRO, locality, and property type. Use Brickplot's calculator for a quick figure.
Pay Stamp Duty Online
Go to Kaveri Online (kaveri.karnataka.gov.in). Choose "e-Stamp" under the Citizen Services menu. Enter property details, select document type (Sale Deed / Agreement for Sale), and pay online. Print the e-Stamp with the Unique Identification Number (UIN).
Prepare the Sale Deed / Agreement
Draft the Agreement for Sale or Sale Deed with your advocate. The document must include: full property description, sale consideration, payment schedule, possession date (for AFS), OC commitment (for AFS on under-construction), and title warranty clause.
Book SRO Appointment
Book an appointment on Kaveri Online under "Appointment for Deed Registration". Select the SRO jurisdiction, date, and time. Walk-in appointments are accepted at most SROs but may involve longer waits.
Attend SRO with All Documents
Both buyer and seller (or their POA holders) must be present. The SRO officer will verify identity via biometric authentication (fingerprint). The document is executed in the officer's presence.
Collect Registered Document
After registration, the SRO stamps the document with the registration number. The registered copy is handed over immediately or within 1–3 days depending on the SRO. Keep the original safely — it is your primary title document.

5. Market Value vs Agreement Value — What to Know
Stamp duty in Karnataka is calculated on the higher of:
Agreement Value
The actual price you are paying the seller / builder. This is the amount stated in the Agreement for Sale or Sale Deed.
Guidance Value (Circle Rate)
The state government's minimum per-sqft or per-sqm value for a property in each locality, published on the Kaveri Online portal. Updated annually.
In most parts of Bangalore, the guidance value is lower than actual market prices, meaning stamp duty is typically paid on the agreement value. However, in some localities where guidance values were recently revised upward (like parts of Whitefield), guidance value may exceed the agreement price — and stamp duty must be paid on the higher guidance value.
Practical tip: Check the guidance value on Kaveri Online before finalising your agreement price. If guidance value is higher than your deal price, you will have to pay stamp duty on guidance value regardless — factor this into your negotiation.
For under-construction flats, stamp duty on the Agreement for Sale is calculated on the total consideration (land component + construction component). Some builders split these to reduce the apparent base value, but the SRO can reject such arrangements and insist on total consideration. Consult your advocate on the correct structure for your agreement.
6. Frequently Asked Questions
What is the stamp duty rate for a flat in Bangalore in 2026?
In Bangalore (Karnataka) for 2026, the stamp duty rate depends on the property value: Properties up to ₹20 lakhs: 2%. Properties between ₹20L and ₹45L: 3%. Properties above ₹45L: 5.6% (comprising 5% stamp duty + 0.5% KSFDC cess + 0.1% local body cess). Additionally, a registration fee of 1% of the property value is payable. So for a ₹1 crore flat, total registration cost = ₹5.6L stamp duty + ₹1L registration fee = ₹6.6L.
What is the difference between market value and agreement value for stamp duty?
Stamp duty must be paid on the higher of (a) the agreement value (the price you are paying), or (b) the government's guidance value (also called circle rate or market value). The guidance value is the minimum value per square metre that the government recognises for a given locality. It is published annually by the State Revenue Department on the Kaveri Online portal. If you buy a flat for ₹80L but the guidance value for the same flat size in that locality computes to ₹90L, you pay stamp duty on ₹90L.
Can I register a flat without physically visiting the SRO in Bangalore?
No. Property registration in Karnataka requires the physical presence of both buyer and seller (or their authorised Power of Attorney holder) at the Sub-Registrar's Office. Biometric verification of both parties is required. However, you can complete all preparatory steps online: stamp duty payment via e-Stamp, appointment booking on the Kaveri Online portal, and document preparation. The physical SRO appointment is the final step.
How soon should I register the flat after signing the Agreement for Sale?
RERA mandates that the Agreement for Sale must be registered within 4 months of signing. For an under-construction flat, the sale agreement (not the conveyance deed) must be registered. The final conveyance deed (absolute sale deed) is registered when the flat is ready for possession and the full consideration is paid. It is advisable to register the Agreement for Sale as soon as possible — an unregistered agreement offers significantly weaker legal protection if the builder defaults.
