More cities will take part in a government survey on a proposed property tax and its implementation scheme. Yang Suizhou, a deputy chief of the State Administration of Taxation's local tax division, said the government would further expand the consultation by adding five more cities to the survey, without identifying them. The provinces of Anhui, Henan, Fujian, Liaoning and Jiangsu, the autonomous region of Ningxia, and the autonomous municipalities of Beijing, Tianjin, Shenzhen and Chongqing were picked initially to take part in the study on tax reform and how to collect the new tax. Faced with a complicated tax system, the state must do a lot of research and carry out trials to ensure a smooth tax collection process, Soufun.com quoted Mr Yang as saying. The proposed tax is the latest move to put a lid on property prices. The central government suggested introducing a property tax in 2003, along the lines of Hong Kong's tax regime, which bases the tax rate on the size of the premises. Rumour has it that the tax will be introduced this year, but many developers say the complicated tax system would be hard to implement so soon.
