KMC Property Tax: How to Calculate It, How to Pay It, and What Most People Get Wrong
Owning property in Kolkata comes with one non-negotiable responsibility — paying your KMC property tax on time. Miss it, and you're not just looking at a penalty. You could end up with dues compounding for years, making a small oversight feel very expensive very fast.
The good news? The Kolkata Municipal Corporation has made the process reasonably straightforward — both online and offline. You just need to know what you're doing.
KMC property tax is the charge levied by the Kolkata Municipal Corporation on all real estate within the city's jurisdiction. Residential homes, commercial spaces, industrial units, institutional properties, even vacant plots — everything falls under this.
This isn't just a fee. It's the primary revenue source that keeps Kolkata's basic civic machinery running — waste management, road repair, infrastructure projects, the works. So yes, skipping it has consequences beyond just your own wallet.
The tax amount isn't fixed across the board. It's calculated based on the Annual Valuation (AV) of your specific property, using a tiered structure that the KMC calls the Unit Area Assessment scheme.
Back in March 2017, the Kolkata Municipal Corporation introduced the Unit Area Assessment (UAA) scheme to replace the older, more opaque method of property valuation. The idea was simple — let property owners calculate their own tax rather than depending entirely on corporation assessors.
Here's how the system works.
Kolkata is divided into 293 blocks, which are further classified into 7 categories — A through G — based on market value, infrastructure quality, and available facilities. Each category carries a Base Unit Area Value, or BUAV, measured in rupees per square foot.

Category A is your prime real estate — highest value, highest BUAV. Category G covers Kolkata's slum areas, keeping the tax burden minimal for economically weaker sections. Category E is reserved for Refugee Rehabilitation colonies and areas under government EWS and BSUP schemes.
Around 6 lakh property taxpayers across Kolkata are covered under this uniform scheme.
But here's where it gets a little more nuanced.
The BUAV alone doesn't determine your tax. The KMC uses Multiplicative Factors (MF) to adjust the base value depending on several variables — road width, building age, how the property is used, who occupies it, and what it's built with.
Two houses in the same block can end up with very different tax bills because of these factors.

All those factors come together in one formula:
Annual Tax = BUAV × Covered Space or Land Area × Location MF × Usage MF × Age MF × Structure MF × Occupancy MF × Rate of Tax (including HB Tax)
The HB here stands for Howrah Bridge Tax — applicable only to properties in nearby wards.
Before you run the numbers, make sure your property records are updated and there are no outstanding dues sitting quietly against your account. If something looks off, report it to the KMC before it compounds.

Having trouble with your KMC tax payment or assessment? Here's where to reach them.
Address: The Kolkata Municipal Corporation, 5, S.N. Banerjee Road, Kolkata – 700 013
Phone: +91 33 2286-1000
Call Centre: 155360 / 2226-9909 / 18003453375 (Available Monday to Friday, 10:00 AM to 6:00 PM)
A: Your Assessee Number is printed on your previous KMC property tax bill or receipt. If you don't have an old bill, you can visit the KMC office at 5, S.N. Banerjee Road with your property documents and request the number from the Assessment department. It's also sometimes retrievable through the KMC portal using your address details.
A: The KMC online tax payment portal requires your Assessee Number to search for dues. If you don't have it, you'll need to visit the ward office physically and request a fresh assessment or recover the number from records. It's advisable to keep this number saved — you'll need it every time.
A: The Kolkata Municipal Corporation typically sets March 31st as the due date for annual property tax payment. However, KMC occasionally extends deadlines or announces special windows — especially when new waiver schemes are introduced. Check the KMC official portal or call 155360 for current deadline information.
A: Log in to the KMC official website, go to Online Services → Assessment Collection → Reprint E-receipt. Enter your Assessee Number and the date range of payment. Your KMC property tax bill will be available to download as a PDF. This works for all online payments made through the portal.
A: Yes. If property tax remains unpaid, the KMC charges a penalty of up to 15% of the outstanding amount as a one-time fine, plus interest on the dues. However, the 2024 waiver scheme significantly reduces these charges for long-term defaulters — the longer the default period, the lower the percentage of fine waiver you receive.
A: For a residential flat, the calcutta corporation tax is calculated using the UAA formula — BUAV multiplied by the flat's covered area, adjusted by multiplicative factors for location, building age, structure type, occupancy, and usage. For most standard residential flats under owner occupation, the usage MF is 1 and occupancy MF is also 1, making the calculation relatively straightforward.
A: Yes. The KMC bill payment portal accepts UPI payments during checkout. You can scan the QR code or enter your UPI ID on the payment page after entering your Assessee Number. There is currently no dedicated KMC mobile app — the payment is done through the web portal, which is mobile-browser compatible.
A: For offline payment at the KMC office, carry your previous tax receipt (if available), your Assessee Number, and a valid ID proof. If it's your first time paying or you've recently purchased the property, bring your property registration documents to help officials trace the account.
A: In most cases, online KMC property tax payments reflect within 24 to 48 hours on the portal. If you pay via UPI or debit card, it usually processes faster. Always download the e-receipt immediately after payment — don't wait for the portal to update before you have proof.
A: Yes. The KMC tax applies to vacant land as well. The usage multiplicative factor for vacant land up to 5 katha (not falling under other special categories) is 2, while vacant land above 5 katha carries a significantly higher MF of 8, making it one of the higher-taxed categories under the UAA scheme.
