#1. (25 marks) Consider a Canadian family of six two adults and four children (all under 16). There are two wage earners in the family the husband's income is $46,000 and the wife's income is $13,000. Also assume that only federal personal income taxes are paid (that is, ignore provincial taxes) and use 2019 brackets and rates. (a) If the husband's income increases by $8,000, by how much does his PIT liability increase? (b) If we consider the same income increase as in (a) but look at the payroll taxes CPP and EI. Given that the employee's share of CPP is 5.1% and of El is 1.62%, by how much does his payroll tax liability increase? The individual income limit for CPP is $57,400 and for EI is $53,100. Also calculate the changes in the CPP and EI tax credits due to this payroll tax liability increase. (c) If the husband's income increases by $8,000, by how much does his tax liability increase due to the GST credit clawback? The GST credit is clawed back by 5% of the amount by which the family income exceeds $37,789 but under $61,629. (d) Now consider the Canada Child Benefit (CCB). It is clawed back by 23% if the family income is between $30,450 and $65,976 and by 9.5% if the family income exceeds $65,976. By how much does the husband's tax liability increase due to the CCB clawback when his income increases by $8,000? Combining (a), (b), (c) and (d), what is his effective MTR? #1.
