Statistics Canada has a long history of using tax data coming from the Canada Revenue Agency. At first, tax data were used in indirect ways such as data confrontation and frame maintenance. However in the late 1990s in response to respondent burden issues and fiscal restraints, Statistics Canada developed a strategy to significantly increase the use of tax data. This strategy included using tax data to replace survey data, to fill data gaps and to improve the edit and imputation processes of economic surveys. Today, tax data are an integral part of the economic statistics program. They are used to estimate the contribution of small units in the population, to replace survey data for many medium sized units and as auxiliary information in the edit and imputation processes. The successful integration of tax data into the economic statistics program at Statistics Canada would not have been possible without the development of a solid partnership and a legal framework between Statistics Canada and the Canada Revenue Agency. In this paper, we discuss the Statistics Canada/Canada Revenue Agency partnership and how tax data are used within Statistics Canada's statistical programs.
