With barely four days left for the deadline to pay property tax, the Federation of Retail Traders' Welfare Association (FRTWA) has requested the civic body and the state government to extend the deadline of another six months from June 30. In his appeal, Viren Shah, FRTWA's president said that an extension is required as there is a huge confusion in the method of computing property tax. ``Of 2.7 lakh bills were issued by the government, technical discrepancies were found in 20,000 bills. The civic body has further, received 40,777 complaints, many of which have not been rectified,'' said Shah.

Senior BMC officials though have rejected Shah's appeal. They said those who have not paid should get ready to shell out 2% penalty per month after the deadline expires.

The FRTWA added that there is a strong objection of increase from 2010 retrospective dates. ``Mumbaikars are not ready to bear such huge taxes on their owned property as there is a fear that after 2015 and 2020 onwards the rates of taxes and amount of tax is very confusing and it may rise upto 40 to 50 times and estimated collection by 2020 is upto Rs 30,000 crores by the BMC in property taxes,'' Shah added.
