One consideration regarding medical FSAs is that the participating employee's entire annual contribution is available at the start of the plan year, commonly January 1, or after the first contribution to the FSA is received by the FSA vendor, depending on the plan. Therefore, if the employee experiences a qualifying event during the first period, the entire amount of the annual contribution can be claimed against the FSA benefits. If the employee is terminated, quits, or is unable to return to work, he or she does not have to repay the money to the employer.
