BMC closed FY2025-26 with a record ₹7,610.9 crore in property tax collections — 103.68% of target — and on March 31 alone, ₹399.74 crore hit their servers in a single day. If you own property in Mumbai, your bill for FY2026-27 is already live on the BMC portal, and the deadline to grab the early bird discount is May 31, 2026. Miss it, and you lose a flat 10% savings. Miss the main deadline (June 30), and you start bleeding 2% monthly interest.
Here is a straight breakdown of how Mumbai property tax works this year, what changed, and how to calculate your exact number.
Early bird discount deadline: May 31, 2026 — get 10% off your full-year bill
Final payment deadline: June 30, 2026
Late payment penalty: 2% per month on the outstanding amount
Ready Reckoner rates: Unchanged from FY2025-26 (no hike for FY27)
Residential tax rate: 0.316% to 0.726% of capital value
Commercial tax rate: 1.2% to 2.3% of capital value
Exemption: Residential units under 500 sq.ft — zero property tax

Why Your FY2026-27 Bill Hasn't Changed Much
The Maharashtra government kept Ready Reckoner (RR) rates unchanged for FY2026-27 — the same rates as last year apply. Since BMC calculates your property tax based on RR rates, this means no increase in the base valuation. Last year (FY2025-26), there was a 3.89% hike in RR rates that pushed bills up across the board. This year, you get a breather.
For property buyers, this is worth understanding. If you bought a flat in Worli or Lower Parel last year, your registration stamp duty was calculated on the same RR rate that your property tax bill uses. No RR hike means your tax bill stays stable — a small but real relief when you're already dealing with EMIs, maintenance, and society charges.
How Mumbai Property Tax Is Calculated — The Capital Value System
Mumbai switched from the old rateable value system to the Capital Value System (CVS) in 2015. Instead of taxing based on estimated rent, BMC now taxes based on the market value of your property. Here is the formula:
Where:
Capital Value = Base Value (RR Rate) × Carpet Area × Construction Type Factor × Age Factor × Floor Factor × Usage Factor
Each factor adjusts the base value up or down depending on your property's specifics. Let me break down each one.
Construction Type Factor
| Construction Type | Weight |
|---|---|
| RCC / Bungalow | 1.00 |
| Semi-permanent / Chawl | 0.60 |
| Under-construction / Vacant land | 0.50 |
Age Factor (Depreciation)
| Year of Construction | Weight | Effect |
|---|---|---|
| After 1985 | 1.00 | No depreciation |
| Between 1945 and 1985 | 0.90 | 10% reduction |
| Before 1945 | 0.80 | 20% reduction |
If you're buying in areas like Dadar West or Prabhadevi, many buildings date from the 1960s-70s and qualify for the 0.90 age factor — a 10% cut off your capital value before the tax rate even applies.
Usage Category
This is where the biggest difference kicks in. Residential properties pay significantly less than commercial ones. BMC applies different tax rates based on how the property is used:
| Property Type | Typical Tax Rate Range | Annual Tax on ₹2 Cr Capital Value |
|---|---|---|
| Residential | 0.316% – 0.726% | ₹6,320 – ₹14,520 |
| Commercial (Office) | 1.2% – 2.0% | ₹24,000 – ₹40,000 |
| Industrial | 1.5% – 2.3% | ₹30,000 – ₹46,000 |
| Open Land (Vacant) | Variable | Based on land area and zone |
For our buyers looking at commercial office space in Andheri East — which topped BMC's ward-level tax collection at ₹719.2 crore in FY26 — the tax burden is roughly 3-4x higher than a residential flat in the same building. Factor that into your yield calculations.
Property Tax by Mumbai Area — What Real Numbers Look Like
To give you a practical sense of how bills vary across the city, here is a comparison for a standard 1,000 sq.ft carpet area residential flat (RCC construction, post-1985) across different localities:
| Area | RR Rate (₹/sq.ft) | Approx. Capital Value | Est. Annual Tax |
|---|---|---|---|
| Worli | ₹45,000 – ₹70,000 | ₹4.5 – 7 Cr | ₹14,000 – ₹50,000 |
| Lower Parel | ₹40,000 – ₹60,000 | ₹4 – 6 Cr | ₹12,600 – ₹43,500 |
| Andheri West | ₹20,000 – ₹35,000 | ₹2 – 3.5 Cr | ₹6,300 – ₹25,400 |
| Dadar West | ₹30,000 – ₹50,000 | ₹3 – 5 Cr | ₹9,500 – ₹36,300 |
| Mira Road | ₹6,000 – ₹10,000 | ₹60L – 1 Cr | ₹1,900 – ₹7,260 |
The spread is massive. A 1,000 sq.ft flat in Worli can cost you ₹50,000/year in property tax. The same size in Mira Road might be under ₹5,000. This is entirely driven by the Ready Reckoner rate for your zone — the higher the RR rate, the higher the capital value, the higher the tax.
Across our 681 listed properties on Property Butler, we see this play out daily. Buyers in Worli (92 listings) need to budget ₹20,000-50,000 annually for property tax on a typical 2BHK-3BHK, while those shopping in suburban locations pay a fraction of that.
Exemptions and Concessions You Should Know About
BMC offers meaningful relief for smaller residential units:
- Under 500 sq.ft carpet area: Completely exempt from property tax. Zero bill. This covers a huge number of 1BHK and studio apartments across Mumbai.
- 500-700 sq.ft carpet area: 60% concession on your property tax bill. So if your calculated tax is ₹10,000, you pay ₹4,000.
- Self-occupied residential: Lower tax rate compared to let-out properties in some ward calculations.
- Properties used for charitable/educational purposes: Partial or full exemption depending on usage certification.
If you are a first-time buyer looking at properties under ₹2 crore, many of those will fall in the 500-700 sq.ft range and qualify for the 60% concession. Check our first-time home buyer FAQ for more on what to budget beyond the purchase price.
How to Pay Property Tax Online — Step by Step
BMC has made this genuinely painless. No ward office visit needed.
- Go to ptaxportal.mcgm.gov.in
- Log in with your property account number (printed on your old tax receipt or bill)
- Enter the captcha and click "Pay Property Tax"
- Review your bill — check that carpet area, usage type, and ward details are correct
- Choose payment method: credit card, debit card, net banking, or UPI
- Complete payment and download the receipt
If you don't know your property account number, you can search by your name and ward on the portal. Your society secretary should also have this on file.
Pro tip: Pay the full year before May 31 to lock in the 10% early bird discount. On a ₹30,000 annual bill, that is ₹3,000 saved for doing nothing more than paying a few weeks early.
What Happens If You Don't Pay
BMC has gotten aggressive. In FY26, they attached 6,922 properties with outstanding dues totalling ₹6,089 crore. Of those, 2,888 defaulters cleared ₹784.32 crore after receiving attachment notices.
Here is the escalation:
- After June 30: 2% monthly interest starts accruing
- Continued default: BMC sends notice, then issues property attachment order
- Extreme default: BMC can seal and auction the property to recover dues
This is not theoretical. BMC has been sealing commercial properties in prime areas for non-payment. The crackdown has only intensified — they kept facilitation centres open on weekends and holidays through March 2026 specifically to chase defaulters.
The RR Rate Connection — Why Buyers Should Care
Here is something most buyers miss: the Ready Reckoner rate affects three costs simultaneously — stamp duty at registration, property tax every year, and capital gains tax when you sell. Since Maharashtra kept RR rates flat for FY2026-27, all three stay stable. We covered this in detail in our Ready Reckoner rate guide for FY2026-27.
For buyers sitting on the fence — this is a year where your ongoing holding cost (property tax) isn't going up. Combined with stable stamp duty, the total acquisition-plus-holding cost is as predictable as it gets in Mumbai real estate.
Frequently Asked Questions
How do I calculate property tax for my Mumbai flat?
Use the formula: Capital Value (RR Rate x Carpet Area x Construction Factor x Age Factor x Floor Factor) multiplied by your applicable tax rate (0.316%-0.726% for residential). The BMC portal at ptaxportal.mcgm.gov.in has a built-in calculator where you enter your ward, carpet area, and property details to get your exact number. For a quick estimate on any of our 681 listed properties, WhatsApp us at +91 84335 11885 and we will run the numbers for you.
Is property tax the same as house tax in Mumbai?
Yes, they refer to the same thing. BMC officially calls it "property tax" but many Mumbai residents still say "house tax" — particularly for residential units. The bill, the calculation method (Capital Value System), and the payment portal are identical regardless of what you call it.
My flat is under 500 sq.ft — do I still need to pay property tax?
No. Residential units with carpet area below 500 sq.ft are fully exempt from BMC property tax. Units between 500-700 sq.ft get a 60% concession. Make sure your property's carpet area — not built-up or super built-up — is correctly recorded in BMC's system. If there is a discrepancy, visit your ward office with your RERA-registered carpet area documents to get it corrected.
Can I claim property tax as a deduction on my income tax?
Yes, if the property is let out or deemed to be let out. Under Section 24 of the Income Tax Act, municipal taxes paid during the financial year are deductible from the gross annual value of the property. For self-occupied property, since the annual value is nil, there is no separate deduction for property tax — but your overall housing deductions under Section 24(b) for interest still apply. Consult your CA for your specific situation.
What if I just bought a flat — when does my property tax liability start?
Your property tax liability starts from the date of possession or the date of registration, whichever is earlier. For under-construction properties, you pay a reduced rate (0.50 construction factor) until possession. Once you get your occupation certificate and take possession, the full rate kicks in. Make sure the previous owner has cleared all dues before you complete the purchase — outstanding property tax is a charge on the property, not the person, and BMC can come after you for the previous owner's defaults.
