Mandy is itemizing deductions on her federal income tax return and had $6200 in medical expenses last year. If her AGI was $66,0
alisha [4.7K]
Multiply your total income by .075. Compare this number with the estimated total of your medical expenses. If you believe your total expenses were over 7.5% of your income, you qualify for the deduction.

.075*66,000= $4950

Subtract this number from the total of your payments calculated above. ($6200)

$6200-$4950= $1250

This is the amount you can deduct from your taxes.

($1250 is the answer)
