Kolkata Property Tax (KMC): Complete Guide to Rates, Calculation & Online Payment

If you own property in the West Bengal capital, you’ve probably come across terms like KMC Kolkata property tax or Kolkata Municipal Corporation property tax. Both of these are ways of referring to the annual property tax collected by the Kolkata Municipal Corporation (KMC). In FY 2024-25, the Assessment Department of the KMC reported a total property tax collection of INR 1,258.53 crore , one of the highest in the nation.

In this guide, we’ll break down everything you need to know about paying your property tax in Kolkata.

What Is the Kolkata Municipal Corporation Property Tax?

The KMC charges an annual property tax on all buildings and land within the city. This tax helps fund essential civic services such as roads, drainage, street lighting, and waste management.

In 2024, the West Bengal government introduced the Unit Area Assessment (UAA) system  to make property tax fairer and more transparent. Under this method, Kolkata is divided into different zones, and each zone has a fixed value per square foot.

How KMC Kolkata Property Tax Is Calculated

Kolkata property tax is calculated under the UAA system, which uses a simple formula:

Annual Property Tax = BUAV × Property Area × Multiplicative Factors × Tax Rate 

Here’s what each term means:

• BUAV (Base Unit Area Value): The fixed value per square foot set for your zone.
• Property Area: The total built-up or covered area of your property.
• Multiplicative Factors: Adjustments based on factors like property use (residential or commercial), age of the building, type of structure, location, and occupancy status.
• Tax Rate: The percentage applied to the assessed value, which varies by category.

For example, if your zone’s BUAV is INR 50 per sq. ft., your property covers 1,000 sq. ft., the combined factors equal 1.2, and the tax rate is 8%, then:

Tax = 50 × 1,000 × 1.2 × 0.08 = INR 4,800 per year.

Note: Additional charges like the Howrah Bridge tax may apply in some wards. 

If you are a home loan aspirant planning your future homeownership expenses, understanding these property-related charges is crucial for long-term budgeting. You can use a home loan EMI calculator to estimate your monthly repayments and plan your finances more effectively.
