Can I deduct the health care expenses on my tax return that are reimbursed through the health care FSA?
No. You cannot claim a tax deduction for the same expenses that are reimbursed tax-free through your health care FSA. But, keep in mind only health care expenses that are more than 7 1/2% of your adjusted gross income can be deducted from your income taxes, and most people do not have enough expenses to take the deduction. So, in a sense, an FSA eliminates the 71/2% threshold.
