Prior to the enactment of the Patient Protection and Affordable Care Act, the Internal Revenue Service permitted employers to enact any maximum annual election for their employees. Patient Protection and Affordable Care Act amended Section 125 such that FSAs may not allow employees to choose an annual election in excess of a limit determined by the Internal Revenue Service. The annual limit was $2,500 for the first plan year beginning after December 31, 2012. The Internal Revenue Service will index subsequent plan years' limits for cost-of-living adjustments. For 2018, this adjustment increases the contribution limit to $2650. Employers have the option to limit their employees' annual elections further. This change starts in plan years that begin after December 31, 2012. The limit is applied to each employee, without regard to whether the employee has a spouse or children. Non-elective contributions made by the employer that are not deducted from the employee's wages are not counted against the limit. An employee employed by multiple unrelated employers may elect an amount up to the limit under each employer's plan. The limit does not apply to health savings accounts, health reimbursement arrangements, or the employee's share of the cost of employer-sponsored health insurance coverage.
