India Municipal Property Tax Calculator (Bengaluru & Mumbai)

Indian municipal property tax is not one system -- it is whatever formula each city's own municipal corporation has adopted, and the differences are not cosmetic. This calculator deliberately covers only two cities, chosen specifically because their valuation methods are genuinely different, not similar systems with different numbers plugged in: all amounts are in Indian Rupees (₹, INR).

• BBMP Bengaluru uses a Unit Area Value (UAV) system: your locality is classified into a value zone (A through F) based on the Karnataka government's own guidance value for that street, and tax is computed from a per-square-foot notional value for that zone, adjusted for usage and age, rather than from any market price or government valuation of your specific unit.
• BMC Mumbai uses a Capital Value System (CVS): your property's actual notional capital value is built up by multiplying the state's Ready Reckoner Rate for your exact micro-location by a chain of weighting factors (building construction type, age, floor, category of use), and tax is a percentage of that computed capital value -- structurally closer to a market-value-based property tax than Bengaluru's zone system.

A important, deliberate scope decision. Delhi (MCD), Chennai (GCC), Hyderabad (GHMC), and Kolkata (KMC) were all investigated for inclusion in this calculator, specifically because Delhi's Unit Area System is often cited as a third distinct method worth comparing. None could be verified to this platform's accuracy standard: Delhi's Unit Area System formula (Annual Value = Unit Area Value × built-up area × use factor × structure factor × age factor × occupancy factor, taxed by A-H colony category) is well-documented, but a current, citable per-category Unit Area Value table or tax rate percentage could not be located from any source, official or otherwise, during research for this calculator. Rather than publish invented numbers for Delhi (or guess at Chennai, Hyderabad, or Kolkata's current rates), this calculator covers only Bengaluru and Mumbai, where genuine primary-source material was found. If you need a Delhi, Chennai, Hyderabad, or Kolkata property tax estimate, this calculator does not cover it.

BBMP Bengaluru (Unit Area Value): 1. Gross Unit Area Value = Unit Area Value (₹/sq ft/month for your zone and usage) × built-up area (sq ft) × 10 (BBMP's Self Assessment Scheme annualizes the monthly rate over 10, not 12, months). 2. Net Unit Area Value = Gross Unit Area Value × (1 − depreciation %), where depreciation depends on the property's age per BBMP's notified schedule. 3. Base tax = Net Unit Area Value × 20% (BBMP's general tax rate). 4. Cess = Base tax × 24% (a cess computed on the tax itself, not on the property value). 5. A 5% rebate applies if you pay the full year's tax in one lump sum by the early-payment deadline; a 50% exemption applies to ex-servicemen under KMC Act 1976 Section 110(1A).

BMC Mumbai (Capital Value System): 1. Capital Value = Ready Reckoner Rate (₹/sq ft for your exact micro-location) × Building-Type factor (1.00 for RCC construction, 0.70 for non-RCC/pucca) × Age factor (1.00 for a 0-5-year-old building, sliding down to 0.50 for a building over 49 years old) × Floor factor (1.00 for nearly all buildings) × Carpet area (sq ft). 2. Property Tax = Capital Value × the applicable tax rate for your usage category (residential, commercial/industrial, or vacant land). 3. 500 sq ft exemption: a residential unit with 500 sq ft (46.25 sq m) carpet area or less pays zero property tax, under Maharashtra Act 25 of 21 March 2022, effective 1 January 2022 -- a full waiver, not merely a capped or frozen tax.

Bengaluru, Zone C, self-occupied residential, 1,200 sq ft built-up area, 5% depreciation, early-payment rebate claimed: 1. Gross Unit Area Value: ₹3.60/sq ft/month × 1,200 sq ft × 10 = ₹43,200 2. Net Unit Area Value after 5% depreciation: ₹43,200 × 0.95 = ₹41,040 3. Base tax (20%): ₹8,208 4. Cess (24% of tax): ₹1,969.92 5. Tax before rebate: ₹8,208 + ₹1,969.92 = ₹10,177.92 6. 5% early-payment rebate: −₹508.90 7. Final tax payable: ₹9,669.02

Mumbai, 600 sq ft residential RCC flat, 10 years old, Ready Reckoner Rate ₹25,000/sq ft: 1. Age factor at 10 years (interpolated between the confirmed 1.00-at-5-years and 0.50-at-49-years anchors): 0.9432 2. Capital Value: ₹25,000 × 1.00 (RCC) × 0.9432 × 1.00 (floor) × 600 sq ft = ₹1,41,47,727 3. Tax at 0.78% of Capital Value: ₹1,10,352.27

The same Mumbai flat at only 450 sq ft carpet area instead: ₹0, fully exempt under the 500 sq ft rule.

• Cities not covered. Only Bengaluru (BBMP) and Mumbai (BMC) are modeled. Delhi, Chennai, Hyderabad, Kolkata, and every other Indian city are explicitly NOT covered -- see Overview above for why Delhi specifically was investigated and excluded.
• Exact current per-zone BBMP rates. The zone-by-zone Unit Area Value rates used as defaults here are illustrative/representative figures widely cited in secondary sources, not pulled from a directly-loaded official current rate table. Confirm your property's exact BBMP-notified UAV using BBMP's own SAS self-assessment calculator before relying on this figure for an actual payment.
• Exact current BMC tax rate. The 0.78%/1.9%/3.52% rates used as defaults are the officially-confirmed rates effective 1 April 2015 from MCGM's own published rules; BMC revises rates only once every 5 years, and secondary sources suggest the current residential rate may now be materially lower (roughly 0.316%-0.726%), which could not be confirmed against a specific post-2015-16 official notification. This calculator lets you override the rate directly if you know your current bill's actual percentage.
• BMC's intermediate age-factor brackets. Only the two endpoints (1.00 at 0-5 years, 0.50 above 49 years) were officially confirmed; this calculator linearly interpolates between them, while the actual official schedule may use discrete step brackets instead.
• Water tax, sewerage tax, education cess, and other BMC sub-components. Mumbai's actual bill bundles General Tax with several other named components (Water Tax, Water Benefit Tax, Sewerage Tax, Sewerage Benefit Tax, Education Cess, Employment Guarantee Cess, Tree Cess, Street Tax); this calculator models the combined effective rate, not each line item separately.
• Late-payment penalties and rebate deadlines. Both cities' rebates and penalties are date-driven; this calculator assumes you either do or don't qualify, without modeling the specific payment date.

• Assuming Bengaluru and Mumbai use the same kind of formula with different numbers. They don't -- Bengaluru's UAV system is a zone-based notional value system explicitly designed around the absence of a public rental registry, while Mumbai's Capital Value System is closer to a market-value-based tax built from the state's own Ready Reckoner Rate.
• Forgetting Mumbai's full exemption for small residential units. A 500-sq-ft-or-less residential flat in Mumbai owes zero property tax -- an easy detail to miss if you assume all property tax scales smoothly with size.
• Missing BBMP's 5% early-payment rebate deadline. It only applies to a lump-sum payment made by the scheme's specified early date each year, not to any payment made during the year.
• Using a citywide average Ready Reckoner Rate for Mumbai. Rates vary enormously by micro-location within Mumbai; a citywide average will materially misstate your actual Capital Value in either direction.
• Assuming this calculator covers Delhi, Chennai, Hyderabad, or Kolkata. It deliberately does not, for the accuracy reasons explained above -- do not extrapolate these two cities' figures to any other city.

• BBMP Bengaluru: zone system (A-F), age-based depreciation, the 5% early/lump-sum payment rebate, the 50% ex-servicemen exemption under KMC Act 1976 Sec 110(1A), and the general UAV mechanic are confirmed directly from BBMP's own property-tax portal FAQ document (bbmptax.karnataka.gov.in/documents/FAQs.pdf) -- primary-source confidence. The specific 20% general tax rate, 24% cess rate, 10-month annualization convention, and per-zone illustrative Rupee UAV rates are corroborated across multiple independent secondary sources describing BBMP's long-standing Self Assessment Scheme formula, but could not be re-confirmed against a directly-loaded current official rate-table PDF -- secondary-source confidence for those specific figures.
• BMC Mumbai: the Capital Value formula (Base Value × User-Category × Nature-of-Building × Age-Factor × Floor-Factor × Carpet Area), the officially-published 1 April 2015 rate table (Residential 0.78%, Commercial/Industrial 1.9%, vacant land 3.52%), the 5-year revision cycle with a 40%-of-prior-year cap on revision-year increases, and the full 500-sq-ft residential exemption (Maharashtra Act 25 of 21 March 2022, effective 1 January 2022) are all confirmed directly from the MCGM RTI Manual, Chapter 6, Manual V ("Rules for Fixing Capital Value of Lands and Buildings," portal.mcgm.gov.in) -- primary-source confidence. Whether the tax rate has since been revised for a later cycle (secondary sources suggest a lower current residential range) could not be confirmed this session and is exposed as an adjustable input.
• Delhi (MCD), Chennai (GCC), Hyderabad (GHMC), and Kolkata (KMC): investigated for inclusion; excluded because current, verifiable rate/valuation figures could not be located from any source during research for this calculator.
