Section 125 plan pros and cons, honestly

If you have read what a Section 125 plan is, you know the idea is simple: employees pay for certain benefits before tax. Whether it is worth setting one up depends on your headcount, your entity type, and how much of the pitch you are hearing is about the plan itself versus the add-ons sold on top of it. Here is the honest version of both columns.

Where a Section 125 plan helps

• Employees keep more of their paycheck on premiums they were going to pay anyway.
• The employer's payroll tax bill drops by 7.65% of every dollar employees elect pre-tax. At 50 or 100 people that is real money.
• A premium-only plan is cheap to set up and simple to run. The plan document is the main cost.
• FSAs and dependent care accounts fit under the same plan once it exists.
• It is a 45-year-old section of the tax code, not a loophole. Done plainly, nobody at the IRS blinks.

Where it costs you

• Owners are excluded. More-than-2% S-corp shareholders, partners, LLC members taxed as partners, and their close family cannot participate.
• Elections lock for the plan year. Employees can only change them after a qualifying life event, and the rules for that are specific.
• Nondiscrimination testing is real. A plan that favors the highly paid can lose its tax treatment for them. Ask who runs the test and when.
• Lower reported wages can trim Social Security credit and some disability or loan calculations for employees. Small, but worth saying out loud.
• The aggressive designs carry the risk. The plan itself does not; the add-ons do.

What to watch out for

A "Section 125 wellness plan" or "preventive care management program" is a specific design: a pre-tax premium for a wellness or indemnity benefit, with cash coming back to the employee. In June 2023 the IRS said in Chief Counsel Advice 202323006 that the cash-back part is taxable wages when it is not tied to an actual medical expense. That does not make every plan illegal. It makes the details the whole game, and it puts the burden of proof on the plan, not on you.

Signs a pitch has not done that work:

1. "IRS-approved." The IRS does not approve plan designs.
2. Savings several times larger than the 7.65% arithmetic. Ask what design produces the number, then read that design, not the summary.
3. No insurance carrier by legal name. Every indemnity or wellness benefit has an insurer behind it. If you cannot verify one, stop.
4. A tax opinion you are not allowed to read. Opinions exist so your CPA can read them.
5. Money flowing back through payroll with no documented medical service. That is exactly what the 2023 memo describes as wages.
6. Pressure to enroll this month. Section 125 has been in the code since 1978. Nothing about it needs a decision before your accountant has looked.

A fair summary

For most companies with more than a dozen employees on the health plan, a premium-only plan is worth having, costs little, and has almost no downside beyond paperwork. The decision that deserves real care is whether to add anything on top of it. If you do, bring the six questions above to the call, and keep the answers in writing.
