Offering employee benefits shouldn’t feel like walking through a compliance minefield. But for many employers, a small misstep in paperwork or plan setup can undo thousands in tax savings and leave the team uncovered.

Section 125 plans are powerful when done right. But far too often, businesses overlook the fine print and run into avoidable IRS trouble.

125 cafeteria plan benefits are straightforward in theory, but stringent in terms of paperwork and regulations, which is the risk. Your plan won’t provide the savings or protections it claims if it isn’t completely compliant.

At Health Sphere, we’ve seen how costly these mistakes can be. That’s why our support is built to keep your plan safe, compliant, and working exactly as intended.

 

Mistake #1: Missing or Incomplete Section 125 Plan Documents

One of the most common and costly mistakes is simply not having the proper documentation in place.

The IRS requires a written plan document for all Section 125 plans, including Premium-Only Plans. This isn’t just a formality. Without a valid, up-to-date plan document, the entire plan is considered invalid, and your pre-tax benefit elections become taxable.

What You Need:

According to official Section 125 document requirements, your POP plan document must include:

• A description of all benefits offered

• The eligibility rules

• Employer contributions (if any)

• Election procedures and rules

• Plan year information

• Procedures for mid-year changes

If your document is outdated, vague, or missing entirely, you’re not compliant, even if you’ve been offering pre-tax benefits for years.

 

Mistake #2: Not Following the Plan Document

Having a valid document isn’t enough. You also have to follow it exactly.

Many employers make the mistake of updating benefits mid-year or allowing employees to make changes without a qualifying life event. But under Section 125 rules, once an employee makes their pre-tax benefit election, it’s locked in for the entire plan year, unless they experience an eligible change (like marriage, birth, or loss of coverage).

Changing benefit elections outside of these parameters, even with good intentions, can disqualify the tax advantages and put the employer at risk during an audit.

 

Mistake #3: Failing to Communicate the Plan to Employees

Another common oversight is not informing employees that a Section 125 POP exists or failing to offer a formal annual enrollment opportunity.

Employees must be:

• Given a Summary Plan Description (SPD) outlining their rights and options

• Allowed to make their elections before the plan year starts (or within 30 days of hire)

If you’ve been deducting premiums on a pre-tax basis without documenting employee elections or giving them proper disclosures, your plan isn’t compliant, even if your intentions were right.

At Health Sphere, we simplify this by providing digital enrollment tools, clear documentation, and a fully managed onboarding process that ensures employees are covered and the employer is protected.

 

Mistake #4: Not Tracking Election Changes and Life Events

Section 125 plans come with strict election rules, and employers must track them closely.

Each employee’s election must be:

• Made before the start of the plan year

• Based on a valid, documented life event, if changed mid-year

• Archived for record-keeping and potential audits

Employers all too frequently permit undocumented, informal changes, such as modifying deductions following a marriage or childbirth, without obtaining a new election form or submitting an SPD.

With Health Sphere’s Revive Plan, we automate compliance tracking and ensure all required records are in place for each participant, removing the administrative burden from your team.

 

Mistake #5: Forgetting to Update the Plan Annually

Your Section 125 POP isn’t a “set it and forget it” arrangement. The IRS requires that your plan:

• Be restated at least every 5 years

• Reflect any changes in benefit offerings or eligibility rules

• Align with federal law and regulatory updates (e.g., ACA compliance, COBRA rules)

Unaware that it is endangering them, many companies continue to function using antiquated plan documents. Even worse, modifications like new health plan providers, adjustments to the contribution structure, or policies pertaining to remote workers frequently necessitate instant plan updates.

At Health Sphere, we ensure your Section 125 plan stays up to date, because even small errors can trigger big consequences.

 

Mistake #6: Non-Compliance with Discrimination Testing

Section 125 POPs must undergo nondiscrimination testing to ensure the plan does not unfairly favour highly compensated employees (HCEs) or key employees.

There are three key tests:

• Eligibility Test

• Contributions and Benefits Test

• Key Employee Concentration Test

Failing any of these could cause tax issues for your top earners. Many small businesses are unaware of these testing requirements, especially if they offer richer coverage or contribution structures to executives.

The Health Sphere platform includes annual testing as part of our fully managed services, so employers remain compliant without having to decipher complex IRS formulas.

 

Mistake #7: Assuming Your Payroll Provider Handles Everything

While your payroll provider may help with deductions, they typically don’t:

• Maintain your Section 125 document

• Run discrimination testing

• Handle employee elections or life event changes

• Track compliance with IRS code sections 125, 213(d), and 105

This is where businesses get caught off guard, assuming automation means compliance. It doesn’t.

Health Sphere bridges this gap by managing the entire plan, from documentation and elections to ongoing audits and updates. You keep the payroll provider you already use; we just make it smarter, safer, and more tax-efficient.
