⚡ Quick Answer

Property tax in Mumbai is an annual tax that the Brihanmumbai Municipal Corporation (BMC) charges on buildings and flats. It is based on the capital value of the property, which depends on factors such as location, size, type of use and age of the building. For a new flat, the tax usually starts once the building is assessed after the Occupancy Certificate.

  • Paid to the BMC, usually in two half-yearly instalments.
  • Calculated on capital value - location, carpet area, use and age matter.
  • Separate from your society maintenance charges.
  • Can be checked and paid online on the BMC portal.

When you buy a flat in Mumbai, the costs do not end with the agreement value, stamp duty and registration. Every year, you will also pay property tax to the city. Many first-time buyers are unsure how this tax is worked out, when it begins for a new flat and how it is different from the maintenance bill their society sends.

This guide explains BMC property tax in plain language – what it pays for, how the capital value system works, when a new flat starts paying, and how to check and pay your bill online. It is general information; exact rates and rules are set by the BMC and can change, so always check the latest details on the official BMC website.

What Is Property Tax in Mumbai?

Property tax is a local tax collected by the municipal corporation on land and buildings within its limits. In Mumbai, this is the Brihanmumbai Municipal Corporation (BMC). The money supports city services such as roads, water supply, drainage, solid waste management, street lighting and public health.

The tax is levied on the property, not on the person. So whoever owns the flat is responsible for paying it, and unpaid dues can stay attached to the property. That is why buyers of resale flats ask for proof that property tax has been paid up to date.

In simple words: property tax is your yearly contribution to the city for the services around your home.

How BMC Property Tax Is Calculated

Mumbai uses a capital value system. Instead of looking only at rent, the BMC estimates the value of the property and applies the tax rates to it. Broadly, the calculation considers:

  • Locationthe ready reckoner value of the area where the building stands.
  • Sizethe carpet area of the flat.
  • Type of useresidential, commercial or other use, each with its own weighting.
  • Nature of buildingthe type of construction, such as an RCC high-rise.
  • Age of buildingolder buildings usually get some depreciation benefit.
  • Floor factorin some cases, the floor on which the flat sits.

The final bill is made up of several components, such as general tax, water tax, sewerage tax and other charges, depending on the services available. Because so many factors are involved, two flats of the same size in different areas can have very different bills.

Carpet area plays a big part here, so it helps to understand the difference between carpet area, built-up and super built-up area.

When Does Property Tax Start for a New Flat?

For an under-construction project, property tax on individual flats usually begins after the building is complete and the BMC has assessed it. This normally happens after the Occupancy Certificate (OC) is issued. Until each flat is assessed separately, the developer may receive a bill for the building as a whole.

  1. OC is issued for the building or wing.
  2. BMC assesses the property and creates property tax accounts.
  3. Bills are raised on the developer or the society, and later on individual flats.
  4. Society is formed and bills are often collected through the society.
  5. Owner pays directly or through the society, depending on how the account is set up.

At possession, ask the developer whether any property tax is collected in advance, how it will be adjusted later, and in whose name the account will be created. Our possession handover checklist lists other questions to ask on that day.

Property Tax vs Maintenance Charges

PointProperty taxMaintenance charges
Paid toBMC (the city)Your housing society
What it coversCity services - roads, water, drainage, wasteBuilding upkeep - security, lifts, cleaning, amenities
How it is setBMC rules based on capital valueSociety budget, usually per sq.ft
FrequencyUsually half-yearlyUsually monthly or quarterly

General overview. Some societies collect property tax along with maintenance and pay the BMC on behalf of members.

Many buyers see one combined bill from their society and assume it is all maintenance. Ask for the break-up. To understand the society side, read maintenance charges, corpus fund and society formation explained.

How to Check and Pay Property Tax Online

  1. Go to the official BMC portal (portal.mcgm.gov.in) and open the property tax section.
  2. Enter your property account number printed on your bill.
  3. Check the bill details - owner name, address, area and amount due.
  4. Pay online using net banking, card or UPI.
  5. Save the receipt with your flat documents. You may need it for resale or a loan.
Tip: pay before the due date. Late payment can attract penalties, and unpaid dues remain on the property.

Planning Property Tax in Your Home Budget

Property tax is one of several running costs of owning a flat, along with maintenance, insurance and utilities. When you compare homes, include these yearly costs, not just the purchase price. Our guide to the true cost of buying a flat in Mumbai covers one-time costs like stamp duty and GST, and home insurance for a new flat covers another yearly expense.

Larger homes in prime locations generally carry a higher property tax bill, so it is worth asking for an estimate from the society or a tax consultant once the building is assessed. Owners of a home loan may also want to read about home loan tax benefits in India.
