Final answer:
Ed may exclude the cost of the copies as a de minimis fringe benefit. This is because the value is relatively low and impractical to account for, and the copies were used for non-profit purposes, thus not required to be included in his gross income.
Step-by-step explanation:
The employee Ed using the copy machine for personal purposes at Mauve Accounting Services must consider whether this constitutes taxable income or not. The correct answer is Ed may exclude the cost of the copies as a de minimis fringe benefit, assuming the personal use does not constitute a significant expense for the employer. A de minimis fringe benefit is one that, considering its value and the frequency with which it is provided, is so small as to make accounting for it unreasonable or impractical.
In Ed's case, the $150 cost of the copies made throughout the year is likely to fall into this category, given that it is relatively low and the copies were used for a non-profit civic organization. This would typically not require inclusion as part of his gross income, thus making option D the correct choice for his tax situation.
