Some employers choose to issue a debit card to their employees who participate in the FSA. Participants may use the debit card to pay for their FSA-eligible expenses at the point of sale. Pharmacies and grocery stores who choose to accept the debit card as payment must disallow transactions at point of sale if the participant attempts to pay for items that are not eligible under an FSA. In addition, employers still must require employees to provide itemized receipts for all expenses charged to the debit card. The IRS allows employers to waive this requirement when an individual uses the debit card at a pharmacy or grocery store that complies with the above procedure. The IRS also allows employers to waive this requirement when the amount charged to the debit card is a multiple of a co-pay of the employee's group health insurance plan. In most cases, the FSA administering firm will prefer actual insurance Explanations of Benefits (EOBs) clearly representing the patient portion of any medical expense, over other, more vague documentation. This requirement is becoming less cumbersome as more insurances allow patients to search for past EOBs on their websites.
