Final answer:
Option D is incorrect because, under the Tax Cuts and Jobs Act of 2017, miscellaneous itemized deductions, including the cost of work-related education, are suspended for tax years 2018 through 2025.
Step-by-step explanation:
The incorrect statement in the tax treatment of education expenses is option D) Sophie is a partner in a CPA firm. She pays out of her own funds to attend an update course on estate and gift tax planning. Sophie can deduct the cost of the course for AGI.
For tax purposes, the cost of education that maintains or improves skills required in one's present employment may be deductible as a miscellaneous itemized deduction. These deductions are limited to the amount that exceeds 2% of the taxpayer's adjusted gross income (AGI) when they are allowed. However, the Tax Cuts and Jobs Act of 2017 suspended miscellaneous itemized deductions for tax years 2018 through 2025, which means that these expenses currently cannot be deducted. Hence, none of the options A, B, and D would currently allow for a deduction.
For someone like Iris, who is reimbursed by her employer for attending an educational course, there is no tax effect because it would typically be classified as a working condition fringe benefit, which is not included in taxable income.
