How Chennai property tax is calculated
The Greater Chennai Corporation (GCC) charges property tax twice a year based on a property's annual rental value — an estimate of what it could earn as rent, not its market price. The value depends on the plinth area, a zone-wise basic rate per square foot, and whether the property is residential or commercial. The estimator above follows this method with editable rates.
The method
The actual GCC computation also applies depreciation by building age and separate components (general tax, education tax, library cess), so treat this as a close estimate and confirm the exact demand on the GCC portal.
A worked example
A 1,000 sq ft self-occupied home at a basic rate of ₹1.50: monthly value = ₹1,500; annual = ₹18,000; after 10% = ₹16,200; at 12.4% that is about ₹2,009 a year, or roughly ₹1,004 per half year.
Paying and saving
- Pay online on the GCC / Namma Chennai portal using your property tax assessment number.
- Due dates are usually 31 March and 30 September; early payment sometimes earns a small incentive.
- Self-occupied residential property is taxed lower than rented or commercial use.
- Keep your assessment updated after any construction — under-declaring invites penalties.
