Final answer:
Megan can deduct $1,780 of her medical and dental expenses on her taxes, excluding the cost of her elective tummy tuck surgery since only expenses above 7.5% of her adjusted gross income are deductible.
Step-by-step explanation:
Megan has various medical and dental expenses that she may be able to deduct on her taxes. Not all expenses qualify for a deduction. The Internal Revenue Service (IRS) allows you to deduct the amount of your medical and dental expenses that exceed 7.5% of your adjusted gross income on Schedule A (Form 1040), line 4.
First, we need to determine which of Megan's expenses are qualified medical expenses. The elective tummy tuck surgery is not considered a qualified medical expense because it is cosmetic. This leaves us with the prescriptions ($1,480), doctor copays ($950), dental bills ($2,800), and health insurance premiums ($1,800) as potentially deductible. The total of these expenses is $7,030 ($1,480 + $950 + $2,800 + $1,800).
Megan's adjustable gross income (AGI) is $70,000. So, 7.5% of her AGI is $5,250 ($70,000 * 0.075). To calculate her allowable deductions, we subtract this amount from her total qualified expenses. Therefore, Megan can report $1,780 ($7,030 - $5,250) of allowable medical and dental expenses on Schedule A (Form 1040), line 4.
