The City of Macroville hires you as a consultant to help establish a procedure to simplify its property tax collection processing and make the process more efficient. Currently the city and six special districts receive money from a property tax. Each district and the city has its own billing, recording, and collection functions. In addition, the taxpayers are upset about paying seven different tax bills. At a recent town hall-type meeting, several citizens spoke and demanded that the city do something to simplify the process. As a consultant, how would you advise the city?
