Deductions & credits

What is your AGI?  What are your medical expenses?

As previously stated only the amount of medical expenses that is greater than 7.5% of your AGI can be entered as an itemized deduction.

For example if your AGI is $50,000 and your medical expenses are $25,000 then the amount of medical expenses you can deduct is $25,000 - $3,750 ($50,000 * .075) = $21,250
