Tax Question:

Please compute the total tax due (April 30th, 2020) for the following single (non-senior, nonmarried) resident of Ontario.

During the 2019 tax year, they earned $160,000 in (gross) T4 employment income. From this sum, $40,000 was deducted by their employer (for provincial and federal taxes) at source and remitted to the Canada Revenue Agency, which may or may not be enough to cover their tax bill. They also paid the full Canadian Pension Plan (CPP) premiums and Employment Insurance (EI) premiums for 2019. They contributed $10,000 to an RRSP and plans to utilize the entire deduction. In addition, they received $3,500 in interest income from a Canadian bank and $350 in dividends from her stockholdings (which involved only Canadian companies). Lastly, they provided 4.5 hours of volunteer service to their local fire department each Sunday and made $6,500 in charitable contributions during the 2019 tax year.
