Preliminary statistics explanatory notes

The Preliminary Statistics present data based on the universe of all 2011 tax year returns. This represents about 95% of the expected number of returns to be filed for the 2011 tax year. The initial assessment values are used to produce the tables. Any changes to the assessment as a result of Agency or taxpayer initiated reassessments are not included in the Preliminary Statistics.

These Preliminary Statistics contain Tables 1 to 5A. They use data from personal tax returns filed two years earlier. For example, the 2013 edition of the tables analyzes returns from the 2011 tax year, which generally had to be filed by the end of April 2013. The number of items in Tables 2-5A has been expanded and now present data for 113 items. All counts and amounts in this publication can be subject to revision.

Please note that the RRSP transfer amounts are not included in other income, other pension or superannuation income, and RRSP income.

Confidentiality procedures

To ensure the protection of taxfiler information, data have been suppressed where warranted. As well, counts are rounded to the nearest multiple of 10. For example, 104 would be rounded to 100 and 105 would be rounded to 110. Dollar amounts have been rounded to the nearest thousand in Tables 2 to 5A, and to the nearest million in Table 1. Totals may not add up due to rounding or suppression.
