I am quitting my job and my last day will be December 2. Can I terminate my flexible spending account so that the payroll deductions are not taken from the final paycheck?

If you are terminating employment, all pending deductions must be met prior to receiving a payment. FSA deductions are considered as a current deduction so in this case, if you work two days in December, you would be obligated to honor your pledge amount for December. For example, if you are a semi-monthly employee, you will not get paid for your time worked on December 1^st and 2^nd until the December 31^st paycheck. Therefore the deduction on December 31^st is for a time period during which you were an active employee.
