Stamp duty on a flat purchase in West Bengal is about 6% of the higher of the agreement value or the government market value inside a municipal or corporation area, and about 5% in a panchayat area, with one percentage point added where the value exceeds ₹1 crore. A flat registration fee of a flat 1% of that same value is charged on top. Inside Kolkata the buying cost is therefore roughly 7% of value up to ₹1 crore and 8% above it.
These are the full baseline rates. The pandemic-era reduction that many buyers still remember ended on 30 June 2024, so a buyer budgeting today should not plan around any rebate. The figure that matters is not your negotiated price but the government's assessed market value, and the higher of the two is what is charged.
The current rates at a glance
| Location and value | Stamp duty | Registration fee |
|---|---|---|
| Kolkata, Howrah and other municipal or corporation areas, up to ₹1 crore | about 6% | 1% |
| Same areas, above ₹1 crore | about 7% | 1% |
| Panchayat area, up to ₹1 crore | about 5% | 1% |
| Panchayat area, above ₹1 crore | about 6% | 1% |
There is no separate, lower rate for women buyers in West Bengal. Men and women pay the same rates. Where the flat is a registered flat in a housing society or an apartment project, the transaction follows the ordinary conveyance rate; the classification turns on whether the property lies within a corporation, a municipality or a notified area, or in a rural panchayat area.
Charge is on the higher of price or circle rate
West Bengal does not charge duty on your agreement price alone. The registering officer uses the government's assessed market value, often called the circle rate or, in West Bengal, the market value assessed by the registration department. Where the assessed value is higher than the price you paid, the duty is computed on the assessed value. Suppose you buy a flat in Kolkata for ₹65,00,000 but the assessed value is ₹70,00,000: the duty is charged on ₹70,00,000, and stating the lower figure in the deed will not reduce it.
The assessed value is checked through the department's online market-value assessment for the relevant mouza and holding. Because the value depends on the locality, the floor and the recorded area, it is best to obtain it before you finalise what you will pay, not after.
Worked example
Take an ₹85,00,000 flat inside the Kolkata Municipal Corporation area, where the agreement value is at or above the government market value.
| Charge | Basis | Amount |
|---|---|---|
| Stamp duty | about 6% of ₹85,00,000 | about ₹5,10,000 |
| Registration fee | 1% of ₹85,00,000 | ₹85,000 |
| Total government charges | about ₹5,95,000 |
If the same flat were in a panchayat area instead of the corporation area, the duty would fall to about 5%, or ₹4,25,000, bringing the total to roughly ₹5,10,000. That one percentage point is the whole reason buyers check whether the address is inside a municipal boundary.
Buying an under-construction flat
Where you buy an under-construction flat, the agreement for sale and the later conveyance are two stages. An agreement for sale of such a flat attracts a lower stamp duty, and the amount already paid is adjusted against the duty on the final conveyance deed, so you are not charged twice on the full value. The practical consequence is that the first payment is smaller than a completed-sale purchase, and the larger duty falls due at conveyance. Buyers should keep the receipts from the agreement stage, because they are credited later.
How the purchase is registered
Registration of a flat purchase in West Bengal runs through the state's online system, with the e-Nathikaran service handling much of the processing. The steps are broadly:
- The deed is drafted on the agreed terms, showing the correct consideration and the description of the flat.
- An e-requisition is raised and the system computes the stamp duty and registration fee on the relevant value.
- Where the duty exceeds ₹10,000 or the fee exceeds ₹5,000, payment is made electronically through GRIPS.
- The parties attend the sub-registrar's office, identities are verified, and the document is admitted and registered.
The registration fee itself is a flat 1% across urban and rural areas; a few secondary sources quote a slightly higher figure, but the settled position used by most practitioners and departments is 1%. Because individual figures are set by notification, confirm the current amount on the day you register.
Documents needed when you register a flat
Registration is refused, or postponed, when a paper is missing. For a flat in West Bengal keep the following ready:
- The seller's original title deed and the chain of documents proving a clear title.
- The agreement for sale, or the builder-buyer agreement for a new flat.
- Identity and address proof of both parties, and PAN where the transaction is large.
- The latest property tax receipt and the municipal or society holding details.
- A no-objection certificate from the housing society or the developer where one is required.
- Two witnesses for execution, and photographs if the registering officer asks for them.
A missing document can push registration past a loan deadline, so the file is best assembled before the date of presentation is fixed.
The single most useful fact for a buyer is that the rate depends on whether the flat lies inside a corporation, a municipality or a notified area, or in a rural panchayat area. A property on the edge of a municipal boundary can be charged one percentage point more or less depending on which side of the line it falls. Buyers should confirm the classification from the municipal record, not from the developer's brochure or a neighbour's guess.
Stamp duty and the registration fee are payable when the conveyance is registered, which is usually after the price is agreed and around the time of possession. A lender often disburses against a registered sale deed, so the buyer frequently has to fund the government charges from savings rather than out of the loan. On an ₹85,00,000 flat that is close to ₹5,95,000, and it is a cash requirement that must be planned for well in advance.
In a housing project the developer's conveyance to the association and the buyer's own conveyance are separate steps. The buyer registers the transfer that gives the individual flat, or the undivided interest that goes with it.
The deed is registered at the sub-registrar's office that has jurisdiction over the property, not over where the buyer lives. A flat in south Kolkata is registered at the office covering that locality, and a land parcel at the office for its sub-district. Presenting at the wrong office is a frequent, and entirely avoidable, cause of delay.
Check the papers before the money moves
Before paying the price, confirm the seller's title, the municipal holding number, the latest tax receipt, and whether any mortgage or charge subsists on the flat. Stamp duty and registration record a transfer; they cannot cure a defective title. If the title chain is incomplete, fix it before registration, because after you have paid and registered you are in a much weaker position. Our property title search checklist for West Bengal sets out what to look for.
After registration: mutation and society records
Registration records the transfer, but the flat should then be mutated so that property tax and the municipal record show the buyer. Inside Kolkata that is the Kolkata Municipal Corporation; elsewhere it is the relevant municipality. For a flat in a housing society or apartment association, the change of name in the society's register is a separate step that the buyer must pursue with the managing committee. Delaying mutation does not undo the purchase, but it makes the next sale or loan harder. Our guide to the mutation application for Banglarbhumi or KMC sets out the process.
Budgeting for the total cost
Stamp duty and registration charges together add roughly 6% to 8% to the cost of a flat in West Bengal, depending on the area and whether the value crosses ₹1 crore. That money is due at registration, before possession, and it is not financed by most home loans in the same way as the price. A buyer should therefore set aside the amount in advance and treat it as part of the purchase, not as an afterthought. It is prudent to confirm the assessed value and the exact charges at the sub-registrar's office before signing anything, and to take advice if the transaction is unusual.
