This Case study from Canada.

Your client Amy, a 40-year-old accountant from Ontario, works for ABC Inc. Her annual income from ABC is $60,000. During tax season, Amy prepares tax returns for her friends and earns an extra $2,000.

Each year, Amy contributes $4,000 to an RRSP. Amy's 2-year-old son Oscar, is in daycare 4 days per week, costing $300 per month.

On Fridays, her mother looks after Oscar at no charge.

What is Amys total income for the year? What is her taxable income for the year?

Based on your calculations of Amys total and taxable income, what is Amys total federal tax payable? Is provincial tax payable?

What is Amys marginal tax rate? If she received another $100 of income, how much additional tax would she pay?
