Big Tax Data and Economic Analysis: Effects of Personal Income Tax Reassessments and Delayed Tax Filing - ARCHIVED

This study investigates the extent to which income tax reassessments and delayed tax filing affect the reliability of Canadian administrative tax datasets used for economic analysis. The study is based on individual income tax records from the T1 Personal Master File and Historical Personal Master File for selected years from 1990 to 2010. These datasets contain tax records for approximately 100% of initial and all income tax filers, who submitted returns to the Canada Revenue Agency (CRA) before specific processing cut-off dates.
