Many companies allow employees to set aside a specific dollar amount from their salary each year in a flexible spending account (FSA) to pay for qualifying medical expenses.

You choose to set aside $5,000 in a medical FSA. As you incur medical expenses you would either submit the bills to be paid by the FSA, or request reimbursement from the FSA, up to the $5,000 set aside.

Monies contributed to an FSA are pre-tax for federal income tax (and state income tax in most cases) and FICA (Social Security and Medicare) tax purposes.

If your annual salary is $75,000 and you set aside $5,000 in a medical FSA, the federal wages reported on your Form W-2, as well as the Social Security and Medicare wages, will be $70,000. If you are in the 25% bracket, this $5,000 will save you $1,633 in federal income and FICA taxes, plus possibly a few hundred in state income taxes.

The savings don’t end there, though. Because contributions to a medical FSA reduce taxable wages they also reduce Adjusted Gross Income, and therefore may increase deductions and credits that are affected by AGI.

Under a medical FSA you get an above-the-line deduction for 100% of qualified medical expenses paid through the plan. You do not have to reduce the expenses by 7.5% of your AGI.

Of course medical expenses paid through an FSA are not included in medical costs deducted on Schedule A.
