The 2012 taxation year of the taxpayer (“TD”) ended on October 31, 2012. Under s. 24(1) of the International Business Activity Act (B.C.), it was required to file its 2012 tax return (in which it claimed a refund based on operating an international financial business in B.C.) “within 18 months after the end of the taxation year or within a later period approved by the commissioner.” S. 25(5) of the Interpretation Act provided that “in the calculation of time…the first day must be excluded and the last day included.”
TD provided its 2012 return to a courier in Toronto on April 30, 2014, and the return was not received by the Commissioner (in Victoria) until the next day, May 1, 2014. Before finding that TD’s return had been filed one day late, Frankel JA noted (at para. 41) the TD submission that:
because when a taxation year ends “at the last instant of the last day of the taxation year”, the first day on which a taxpayer can do anything is November 1st…[so that] November 1st is the “first day” and, therefore, the day excluded by operation of s. 25(5) of the Interpretation Act
and then stated (at para. 44):
Although a taxation year ends at the last instant of the last day of that year, it nevertheless ends on that day. Consequently, TD was required to file its return within 18 months after October 31, 2012. By operation of s. 25(5) of the Interpretation Act, October 31, 2012, is excluded, [and] the time for filing began to run on November 1, 2012, and expired on April 30, 2014.
