Section 125 cafeteria plan (noun): a written employer plan under Internal Revenue Code §125 that lets employees choose between taxable cash pay and certain qualified benefits, paying for those benefits with pre-tax salary reductions.
What a cafeteria plan does
A cafeteria plan lets an employee pay certain benefit premiums out of gross pay, before taxes. The salary reduction used to buy health coverage isn't included in the employee's gross income.[1] Premiums paid that way for accident or health insurance are excluded from income under Section 106.[2] The result: taxable wages go down, so the employee owes less income tax and FICA, and the employer owes less FICA on those dollars.[1, 3]
It has to be a written plan, run the way it's written
Pre-tax treatment depends on a written cafeteria plan, consistent elections and proper operation, including nondiscrimination testing.[4] Plans with 100 or more participants generally also carry ERISA paperwork, such as a summary plan description and possibly Form 5500 filings.[5]
Who can participate pre-tax
- Only W-2 employees can pay pre-tax. Partners, more-than-2% S-corporation shareholders and 1099 contractors are treated differently.[6]
- In the program this site covers, not every employee qualifies. Employees must earn enough each week for the deduction to work in their favor, and Elysian screens each employee. In Elysian's case data, roughly 60–80% of a workforce qualified.[7]
Elections are usually locked for the plan year
Under Section 125, elections are generally irrevocable for the plan year unless the employee has a qualifying change in status. One client's authorization form for this program calls the election “irrevocable” for the plan year.[8] Employees should get advance notice and an easy opt-out before coverage starts.[9]
What Section 125 does not decide
Section 125 settles how the premium is taxed. It doesn't decide how benefit payments are taxed. Sections 105 and 104 govern that, and it's where the IRS has drawn its lines on fixed indemnity plans paid pre-tax.[10, 11] Read FICA and payroll tax mechanics and The lines the IRS has drawn next.
