Stamp duty and registration charges are among the largest upfront costs in any Bangalore property purchase, often adding 6–7% on top of the property price. Yet many first-time buyers only discover the exact figure at the Sub-Registrar's office. Here's exactly how these charges work, how they're calculated, and how to avoid common delays.
What Are Stamp Duty and Registration Charges?
Stamp duty is a tax levied by the Karnataka state government on property transactions, paid to make the sale deed a legally valid document. Registration charges are a separate fee paid to officially record the transaction with the Sub-Registrar's office, under the Registration Act. Both are mandatory — a sale deed that isn't registered has no legal standing, regardless of how much was paid for the property.
Think of it like this: when you buy a flat, the price you pay the seller is only part of the bill. The government also charges you a percentage of the property's value just to make the sale official — that's stamp duty. Then there's a separate, smaller fee to actually get your name written into the government's records as the new owner — that's registration. Both are paid together, in one visit to the Sub-Registrar's office, and both are compulsory — skip them, and you don't legally own the property, even if you've paid the seller in full.
Current Rates in Karnataka (Bangalore)
| Property Value | Stamp Duty | Registration Charge |
|---|---|---|
| Below ₹20 lakh | 2% | 2% |
| ₹20 lakh – ₹45 lakh | 3% | 2% |
| Above ₹45 lakh | 5% | 2% |
Say you're buying a flat worth ₹60 lakh. Since it's above ₹45 lakh, stamp duty is charged at 5% — that's ₹3,00,000. Registration is a further 2% — that's ₹1,20,000. So before you've paid a single rupee toward the flat itself, you already owe roughly ₹4,20,000 in government charges, plus whatever cess or surcharge applies in your specific area (more on that below). This is why it's smart to budget an extra 6-7% on top of the property price, not just the price itself.
Important: The registration fee was revised from 1% to 2% effective late August 2025. On top of stamp duty, a BBMP cess and/or surcharge may also apply depending on property location and value — these vary and change periodically, so always confirm the exact applicable charges on the official Kaveri Online Services portal before budgeting for a purchase.
How Is the Value Calculated?
Stamp duty is calculated on the higher of the actual sale price or the government-notified guidance value (also called circle rate) for that locality. If a property is sold below the guidance value on paper, stamp duty is still charged based on the guidance value — a common point of confusion for buyers negotiating below market rate.
Documents Required for Registration

Step-by-Step Registration Process
Common Mistakes That Cause Delays
- ● Underestimating the guidance value and arriving with insufficient stamp duty paid
- ● Mismatched names across PAN, Aadhaar, and the sale deed
- ● Missing or expired Encumbrance Certificate
- ● Witnesses without valid ID proof on the day of registration
- ● Not booking a Sub-Registrar appointment in advance during peak periods
Are There Any Exemptions or Concessions?
Karnataka has periodically offered concessional stamp duty rates for first-time homebuyers and properties below certain value thresholds. These schemes change over time, so it's worth checking current eligibility on the Kaveri portal or with a documentation professional before registration, since a missed concession can mean paying significantly more than necessary.
