Assignment Problem Four - 4 (Individual Tax Payable - 7 Cases) There are seven independent cases which follow. Each case involves various assumptions as to the amount and type of income earned by Ms. Barbra Baines during 2020, as well as to other information that is relevant to the determination of her 2020 Tax Payable. Barbra's Net Income For Tax Purposes is equal to her Taxable Income in all Cases. In those cases where we have assumed that the income was from employment, the employer withheld the maximum El premium and CPP contribution. Case 1 Barbra and her husband, Billy, are both 67 years of age. Billy is sufficiently disabled that he qualifies for the disability tax credit.

Mark is 15 and is physically infirm, but not sufficiently to qualify for the disability tax credit. He has income from part time work as a graphic artist of $3,450. The other child, Sandy, is 12 and is in good health and has no income during the current year. Case 3 Barbra is 58 years old and has income from investments of $102,000. She is divorced and has been awarded custody of her 21 year disabled son. The son qualifies for the disability tax credit.
