Each year, cities plan their budgets by estimating the revenue needed to provide essential services, factoring in cost increases like inflation, new regulations and added responsibilities from other orders of government.
In British Columbia and other Canadian provinces, cities are required to collect their needed taxes based on property value (called "assessment") as established by BC Assessment, a provincial agency. Early in the new year, BC Assessment provides the valuation of all the properties in the province.
After the City sets its budgeted expenditures and once BC Assessment provides those values, the City’s tax division can set the municipal Tax Rate. The Tax Rate (often called the "mill rate"), when multiplied by the total value of all the property, will equal the total revenue needed to be collected from that class of property (residential, commercial, industrial, etc.).
