Karnataka stamp duty and registration charges, explained
Buying property in Karnataka comes with more than just the sale price — stamp duty, a cess, a surcharge and a registration fee stack on top, and the last of those doubled in 2025. Here's exactly how each piece is calculated.

The stamp duty slabs — a flat rate, not a marginal one
Karnataka charges stamp duty on a property sale (conveyance/sale deed) as a flat slab rate on the entire value, unlike income tax's marginal slabs: 2% if the value is up to ₹20,00,000; 3% if it's between ₹20,00,001 and ₹45,00,000; and 5% if it's above ₹45,00,000.
Because the rate applies to the whole value rather than just the portion inside each band, crossing a slab boundary by even ₹1 changes the rate on the entire amount — a property at exactly ₹45,00,000 is taxed at 3% on the full ₹45,00,000 (₹1,35,000), while one at ₹45,00,001 is taxed at 5% on the full amount (over ₹2,25,000).
Guidance value: the floor you can't undercut
Stamp duty and registration fee are both computed on whichever is higher — the sale consideration stated in the deed, or the government's guidance value (also called the circle rate or market value) for that property, published locality-wise. This stops buyers and sellers from under-declaring the price to save on duty.
You can look up the guidance value for a specific survey number, street or apartment on the Kaveri Online Services portal (kaveri.karnataka.gov.in) before signing anything — if the guidance value turns out higher than your agreed price, duty is charged on the guidance value regardless of what you actually paid.
Cess and surcharge: the extra layer on top of stamp duty
On top of the base stamp duty, Karnataka adds a flat 10% cess, plus a surcharge that depends on where the property is located — 2% inside BBMP, City Corporation or City Municipal Council limits (broadly, "urban"), or 3% inside Gram Panchayat limits under BMRDA ("rural"). Both the cess and the surcharge are calculated on the stamp duty amount, not on the property value itself.
At the top 5% slab, this works out to an effective stamp duty of 5.6% of the property value in urban areas (5% × 1.12) and 5.65% in Gram Panchayat areas (5% × 1.13) — before registration fee is even added.
Registration fee: doubled in August 2025
Registration fee is separate from stamp duty and is calculated as a flat percentage of the same value (sale price or guidance value, whichever is higher) — currently 2%, statewide, with no urban/rural distinction. This applies to sale deeds, Joint Development Agreements and General Power of Attorney registrations alike.
Effective 31 August 2025, the Karnataka government doubled this fee from 1% to 2% — the first revision since 2003 — citing a shortfall against the department's stamps-and-registration revenue target. For a ₹50,00,000 property, that single change added ₹50,000 to the closing cost.
A worked example: ₹50,00,000 flat in Bengaluru (BBMP)
Say the sale consideration is ₹50,00,000 and the guidance value is lower, so duty is calculated on ₹50,00,000. This falls in the top slab (above ₹45,00,000), so stamp duty is 5% = ₹2,50,000. Cess adds 10% of that = ₹25,000. Surcharge (BBMP, urban) adds 2% of that = ₹5,000. Total stamp duty comes to ₹2,80,000.
Registration fee is a separate 2% of ₹50,00,000 = ₹1,00,000. Total payable: ₹2,80,000 + ₹1,00,000 = ₹3,80,000 — 7.6% of the property value. In a Gram Panchayat area, the only change is the 3% surcharge (₹7,500 instead of ₹5,000), pushing the total to ₹3,82,500, or 7.65%.
No more concession for women buyers
Karnataka previously offered a 1% stamp duty concession to women buyers, but this was withdrawn under the Registration (Karnataka Amendment) Act, 2024. Stamp duty, cess, surcharge and registration fee are now identical regardless of the buyer's gender.
Is Karnataka stamp duty calculated on the sale price or the guidance value?
Whichever is higher. If the guidance value (circle rate) for the property is higher than what you're actually paying, stamp duty and registration fee are both charged on the guidance value instead. Check the exact figure on the Kaveri Online Services portal before finalising a deal.
Does the stamp duty slab work like income tax slabs?
No. Karnataka stamp duty is a flat rate applied to the entire value once you cross into a slab — not a marginal rate applied only to the portion above each threshold. A property one rupee over ₹45,00,000 is taxed at 5% on the whole amount, not just on the rupee that crossed the line.
What's the difference between the cess and the surcharge?
Both are calculated on the stamp duty amount, not the property value. The cess is a flat 10% statewide. The surcharge depends on location — 2% inside BBMP/Corporation/Municipal Council limits, 3% inside Gram Panchayat (BMRDA) limits.
How much did registration charges increase in 2025?
They doubled — from 1% to 2% of the transaction value — effective 31 August 2025. This was the first revision to Karnataka's registration fee since 2003, and it applies to sale deeds, JDAs and GPAs alike.
