A Costly Oversight: The Importance of a Written Section 125 Plan

Many employers offer popular pre-tax benefits such as health insurance premiums, health FSAs, and dependent care FSAs, assuming that running deductions through payroll on a pre-tax basis is enough. However, one critical component to offering these plans that is often overlooked is that these benefits generally must be offered pursuant to a written Section 125 plan. Often discovered during an audit or transaction, the failure to maintain a written plan document can expose employers to unexpected tax penalties.

What Is a Section 125 Plan?

A Section 125 plan, commonly referred to as a cafeteria plan or Premium Only Plan (POP), provides employees with the option of purchasing employer-sponsored benefits on a pre-tax basis. These plans allow employees to pick between increased total compensation and contributing part of their compensation towards the payment of benefit premiums. Employees that choose to contribute part of their salary to premiums can do so by making an election. These elections are generally irrevocable during the plan year and a new election cannot be made until the next annual open enrollment period. 

Pre-tax salary reductions are only permitted if they are made under a written cafeteria plan. If no written plan exists, or if the document is outdated or inconsistent with actual operations, the IRS may treat all employee contributions as taxable income. A common misconception is that payroll practices or other enrollment materials can substitute for a written plan, however, SPDs, benefit summaries, or other insurance carrier certificates do not replace a Section 125 plan document. The plan must be formally adopted and should clearly spell out:

• Eligible employees
• Benefits offered on a pre-tax basis
• Election rules (including irrevocability and change-in-status events)
• Other administrative provisions required under Section 125.

Offering pre-tax benefits is a valuable tool for both employers and employees, but only when done correctly. We frequently find that employers are not properly handling their pre-tax salary reductions for their benefit plans. Taking the time to confirm a written plan document is in place, up to date, and properly administered can help avoid unnecessary tax penalties.
