It is March 2024 and Allen Marshall has asked you to help him with his 2023 taxes. During your meeting with Allen you learn the following:

• Allen is thirty years old, divorced, and has an eight-year-old son from his former marriage. He pays $500 a month in child support.
• Allen lives in City A, where he is a salesman for a large manufacturing plant. He receives a base salary of $5,000 per month plus a commission of 1% on the sales he makes in the month. His sales were $50,000 every month in 2023.
• Allen moved to City A from City B on December 1st of 2022 when he was promoted and transferred with his company to the office in City A. Allens tax deductible moving expenses totaled $9,500. He did not receive a reimbursement from his employer. He was able to claim $4,500 of this expense on his 2022 tax return. Allen took out a $120,000 mortgage to purchase his new home. His interest payments were $8,400 in 2023.
• In order to perform his work duties, Allen is required to drive his own vehicle and pay for his expenses, for which he is not reimbursed. However, he does receive an allowance of $450 each month which is treated as unreasonable for tax purposes. Allen has a car which he uses seventy-five percent of the time for business purposes. The undepreciated capital cost of the vehicle at the beginning of 2023 was $28,000. Total costs to operate the vehicle are $800 per month. Interest expense on his car loan is $200 per month.
• Allen spends $300 per month on suits for work. He also updates his cell phone regularly and typically spends $1,500 per year on a new phone. Allens cell phone bill is $80 per month, of which twenty-five percent is for personal use.
• Allen takes his files home with him at the end of the day and reviews his sales calls in his home office. He then returns the files to his office at his place of employment in the morning prior to leaving for the day to make sales calls. Allens monthly total expense for his home insurance, property taxes, maintenance, and utilities is $1,000. His home office occupies ten percent of the square footage in his home.
• Allen maximizes his RRSP contribution each year. His earned income in 2022 was $42,000 which consisted of $6,000 in commissions.
