How do you use the property tax calculator?
- Enter the built-up area of your home and any covered or stilt parking, in sq ft.
- Pick your zone (A to F), say if you live in the home or rent it out, and enter the age of the building.
- Read the tax for the year. The building category, payment option, tax rate, cess and the waste user fee are under “Adjust category, payment and rates”.
Your zone depends on the street, not the locality name. Find it on your last tax receipt, or in the 2016 zonal classification on the GBA property tax portal.
How is property tax worked out in Bengaluru?
Bengaluru uses the Unit Area Value (UAV) system. Each street is placed in one of six zones, A to F, and each zone has a monthly value per sq ft for each type of building. A rented-out home is valued at twice the rate of a self-occupied one. The yearly value is the area times that rate times 10 months. Depreciation for the building’s age comes off that value; the tax is 20% of what is left, and a cess of 24% of the tax is added. Paying the whole year’s tax in one go within the rebate window earns a 5% rebate.
How the tax is worked out
(Built-up area + parking × 50%) × UAV × 10Step 1 − depreciation for ageStep 2 × 20% × 1.24Step 3 − 5% rebate (if paid in full in time) + waste user feeWorked example: 1,200 sq ft flat in zone C
A self-occupied RCC flat of 1,200 sq ft in zone C has a UAV of ₹ 2.15, so its gross value is ₹ 25,800. At five years old it gets 6% depreciation, leaving ₹ 24,252. Tax at 20% is ₹ 4,850 and cess ₹ 1,164, a total of ₹ 6,014, or ₹ 5,714 after the 5% rebate. Rented out, the same flat pays ₹ 11,428.
Worked example: the portal’s own sample
The sample calculation on the GBA property tax portal takes a new 2,850 sq ft self-occupied house in zone D at ₹ 1.90. The gross value is ₹ 54,150, 3% depreciation is ₹ 1,625, the tax is ₹ 10,505 and the cess ₹ 2,521: ₹ 13,026 before any rebate, the same as the portal’s figure. A 1,650 sq ft flat in zone B, two years old, with 135 sq ft of covered parking pays ₹ 9,420 after the rebate.
What are the unit area values?
| Zone | I, self-occupied | I, rented | II, self-occupied | III, self-occupied |
|---|---|---|---|---|
| A | ₹ 3.00 | ₹ 6.00 | ₹ 2.40 | ₹ 1.80 |
| B | ₹ 2.40 | ₹ 4.80 | ₹ 2.10 | ₹ 1.50 |
| C | ₹ 2.15 | ₹ 4.30 | ₹ 1.80 | ₹ 1.20 |
| D | ₹ 1.90 | ₹ 3.80 | ₹ 1.50 | ₹ 1.00 |
| E | ₹ 1.50 | ₹ 3.00 | ₹ 0.95 | ₹ 0.60 |
| F | ₹ 1.20 | ₹ 2.40 | ₹ 0.85 | ₹ 0.50 |
Category I is an RCC or Madras terrace building, which covers most flats and houses. Category II is the same, but only where the whole house has cement or red-oxide flooring. Category III is a tiled or sheet roof. Rented rates are twice the self-occupied rates in every category.
What depreciation applies for age?
Depreciation is 3% for a building up to three years old, rising by 3% for every further three years: 6% up to six years, 9% up to nine, and so on to 60% up to 60 years, and 70% after that.
What else can change your bill?
- Paying late: from the 2026-27 dates on the portal, interest on the first half applies from 1 June 2026 and on the second half from 1 December 2026, and a penalty from 29 November 2026. Defaulters pay interest at 2% a month.
- The rebate window for 2026-27 ran from 1 April and was extended by government order to 31 May 2026.
- Zone limits: where a street moved up more than one zone in 2016, it pays the rate of the next zone up, so your demand can be lower than the table suggests.
- Apartment common facilities such as a clubhouse are assessed separately, usually through the owners’ association.
- A solid waste user fee is now collected with the tax. Enter the yearly amount on your bill under Adjust.
