The BMC last year switched from the rateable value system of property tax to the capital value system.
Under the new system, 19% residential properties are facing a two-fold hike in rates.
Those whose taxes haven't increased will also face a hike in 2015. The BMC may also revise its rules.
Rajiv Jalota, additional municipal commissioner, said, “The proposal will be tabled before the standing committee and the corporation for approval."
