Section 125 Advisory Group Introductions

In short A Section 125 SIMERP is a pre-tax payroll structure that reduces employer FICA by an estimated $640 per enrolled W-2 employee per year and raises employee take-home pay by roughly $125 a month, with no change to the existing health plan.

The tax treatment of these plans is contested and employers should have their own counsel review the plan documents.

The arithmetic

Where do the savings actually come from?

Every dollar, shown before you sign. The admin fee comes out of the savings, never out of pocket. That is what zero net cost means. Here is every line of it at your headcount.

Where the savings come from

Employer FICA reduction

7.65%

A second Section 125 pre-tax deduction lowers taxable wages, which lowers your matched payroll tax on those wages.

Employee take-home increase

~$125/mo

The same mechanics raise net pay without a raise. That is why participation averages above 90% once employees see the math.

Reimbursement platform

213(d)

Urgent care, primary care, mental health, pharmacy, and preventive care in one platform. Spouse and up to five dependents at no added employee cost.

Employees keep their existing plan, carriers, and broker. Nothing about their coverage changes.

Side by side

How does a SIMERP compare to a standard Section 125 plan?

Most employers already run a Premium Only Plan. It captures a fraction of what the tax code allows.

The compliance question

Don't take my word for any of this.

Arrangements in this general area have drawn IRS attention, including Chief Counsel Advice Memorandum 202323006. If you have read it, you are right to ask how this plan is structured and how § 105(b) applies to it. Those are questions for your own tax counsel, reading the actual plan documents, not for a website. I am an introducer, not your tax advisor, and I will not tell you the answer is obvious.

Primary sources: 26 U.S. Code § 125 (cafeteria plans) · § 105 (employer-provided accident and health plans) · § 213 (medical expense definitions) · IRS Publication 15-B (Employer's Tax Guide to Fringe Benefits). Read them yourself; we would rather you did.

How it is structured

Self-Insured Medical Expense Reimbursement Plan

  • A second pre-tax deduction is added under your existing § 125 cafeteria plan
  • A self-insured medical reimbursement plan sits beneath it, reimbursing amounts the administrator treats as § 213(d) medical care
  • Lower taxable wages mean lower matched employer FICA
  • Your group health plan, carrier, and broker are untouched
  • Administered by the plan provider, not by this practice

Ask your own advisors

Questions worth putting to counsel

  • Under the plan as written, must an employee incur a medical expense to receive a reimbursement?
  • How does the plan address Treas. Reg. § 1.105-2 and Rev. Rul. 2002-3?
  • What substantiation does the plan actually require, and from whom?
  • Who bears the tax risk if the IRS disagrees, and what exactly does the coverage cover?
  • Has outside counsel issued a written opinion, and can we read it?

Per the plan administrator

Audit protection, included

The plan provider includes an audit-protection program with every enrollment, backed by errors-and-omissions coverage. Ask for the policy and coverage terms in writing, and confirm who the named insured is. Most errors-and-omissions coverage responds to professional negligence by the party who purchased it and does not pay a policyholder's own tax assessments, penalties, or interest. Under the reasoning in Chief Counsel Advice 202323006, liability for recharacterized wages sits with the employer, not the administrator. Ask whether this policy is different.

Common questions

Straight answers.

Still unresolved? Ask directly at nick.gavin@simerpadvisors.org.

Cost

What does it cost the company or the employees?

Zero net cost to either. An admin fee of $40.00 per enrolled employee per month is paid out of the savings the program generates, never out of pocket. The employer nets $53.33 per enrolled employee per month, roughly $640 annually.

Timeline

How quickly do savings begin?

Within the first payroll cycle after go-live, typically 30 days from signing. The employer sees operating budget improvement immediately and employees see higher take-home pay in their first paycheck under the new structure. There are no upfront costs. The admin fee comes out of savings already captured.

Employees

Does anything change for our employees or existing benefits?

Nothing changes. Your existing health plan, carriers, and brokers stay exactly as they are. We add a second Section 125 pre-tax deduction that generates FICA savings. That's it. Employees don't change how they use their current coverage.

Compliance

How does this relate to what the IRS has warned about?

CCA 202323006 addressed fixed-indemnity wellness arrangements. The plan provider takes the position that this structure is different because it is a self-insured medical reimbursement plan under Section 105(b). Whether that distinction holds for your organization is a legal question, and it depends on the plan language, not on marketing. Get the plan documents, give them to your tax counsel, and let them reach their own conclusion. Any advisor who tells you this is settled is overselling.

Approvals

Does this require a board vote or a new contract?

No board vote required. This is a payroll administration change, not a new benefit plan or expenditure. It's handled at the employer level by whoever manages payroll setup.

HR lift

What's the HR lift after implementation?

The provider estimates five to ten minutes per payroll period, with confirmed direct integrations to ADP and Paycor. Treat that estimate skeptically if you run lean. Ask the provider to walk your payroll lead through exactly what their team does and what your staff does, every pay period, including new hires and terminations. A small payroll department is the most common reason an otherwise good fit does not proceed, and it is better to surface that in week one than in month three.

Eligibility

We already have a Section 125 plan. Does that disqualify us?

Most employers already have one, and that's usually the starting point. What most have is the shell of a Section 125 plan covering pre-tax health premiums. What they don't have is the SIMERP structure underneath that captures the full FICA savings. A car without the engine; we add the engine.

Structure

What is the difference between Section 125 and a SIMERP?

Section 125 is the broad IRS provision allowing pre-tax payroll deductions; most employers have a basic Premium Only Plan covering health premiums. A SIMERP is a more advanced structure under Sections 125, 105(b), and 213(d) that generates full FICA savings for employer and employee alike. Only about 2% of employers currently have one.

Fit

What types of employers benefit most?

Any employer with W-2 staff at 30+ hours on an existing group health plan. The strongest results come from stable full-time workforces: manufacturing, professional services, healthcare, school districts, logistics, and staffing. It scales with the number of eligible enrolled employees, so larger full-time workforces see the largest figures. The minimum is 25 enrolled.

Protection

What is the audit protection, exactly?

The plan provider includes an audit-protection program at no additional cost, backed by errors-and-omissions coverage. That is their program and their representation, not mine, and I would not want you relying on my summary of it. Establish four things in writing before you commit: what the policy covers, what it excludes, who the carrier is, and whether coverage extends to your organization or only to the administrator. Most errors-and-omissions coverage responds to professional negligence by the party who purchased it and does not pay a policyholder's own tax assessments, penalties, or interest. Under the reasoning in Chief Counsel Advice 202323006, liability for recharacterized wages sits with the employer, not the administrator. Ask whether this policy is different and read the answer in the policy language.

Tax code

What tax codes govern the SIMERP structure?

Section 125 (cafeteria plan pre-tax deductions), Section 105(b) (employer-provided accident and health plans), and Section 213(d) (qualified medical expense reimbursements). The plan provider also represents that the structure is built to meet ERISA, HIPAA, and ACA requirements. Citing multiple code sections is not itself a defense. The IRS applies substance over form, so what decides the treatment is whether reimbursements are tied to medical expenses the employee actually incurred, not how many provisions the plan documents reference.

P&L

Where does the FICA savings show up on our P&L?

Employer FICA is 7.65% of covered wages, 6.2% for Social Security up to the annual wage base plus 1.45% for Medicare with no cap. It is a payroll tax expense, so it typically sits inside SG&A or within the department wage lines that carry loaded labor cost, depending on how your chart of accounts is built. A reduction flows straight to operating income. It is not a rebate, a credit, or a below-the-line item, and there is no revenue offset to book. Your controller will know exactly which account it lands in.

SG&A

How can we reduce SG&A without cutting headcount or benefits?

Most SG&A reduction requires cutting something a person or a department depends on. Employer payroll tax is one of the few line items where the expense can fall without anyone losing a job, a benefit, or a service. A Section 125 restructure reduces the employer FICA obligation on enrolled employees while leaving the health plan, carrier, broker, and coverage untouched.

Take-home

Can we increase employee take-home pay without raising salaries?

That is the second half of what this structure does. Enrolled employees typically see roughly $125 more per month in net pay at no cost to them, because the restructure changes how the payroll is taxed rather than how much is paid. Payroll cost does not increase. For employers who cannot fund a raise pool, it is one of the few compensation levers that does not hit the budget.

Sizing

How much would a company our size actually save?

The estimate is roughly $640 per enrolled W-2 employee per year to the employer. The number that matters is not headcount but how many employees are full-time W-2 and enrolled in your group health plan, which is usually a fraction of total staff. Part-time workers, employees on a union multiemployer fund, and 1099 contractors are outside it entirely. Employees in positions outside Social Security coverage still generate the 1.45% Medicare portion, so they count for roughly a fifth of the headline figure rather than nothing. A payroll census returns a real number in three to five business days.

Eligibility

Which employees do not qualify?

Anyone who is not W-2 working 30 or more hours per week, the ACA full-time threshold, and enrolled in an employer-sponsored group health plan. In practice that means most part-time and seasonal staff, employees covered by a union multiemployer or Taft-Hartley fund rather than the company plan, independent contractors, and workers in positions outside Social Security coverage, which includes certified staff in many public school districts whose Section 218 Agreement places them in a state retirement system instead. Those employees are not fully excluded: the employer stops paying the 6.2% Social Security portion but still pays 1.45% for Medicare, so the saving is roughly a fifth of the headline figure. Coverage varies by district, not just by state, so it has to be confirmed rather than assumed. The eligible population is often much smaller than total headcount.

Payroll tax

How do we reduce employer payroll tax without changing our health plan?

Employer FICA is 7.65 percent of covered wages. A Section 125 restructure reduces the FICA-taxable wage base on enrolled employees, which lowers the employer’s payroll tax expense. The health plan, carrier, broker, network, and coverage stay exactly as they are. Nothing about the employee’s medical benefits changes. FUTA and, in most states, SUTA fall on the same reduced base.

Layoffs

How do we cut costs without layoffs or benefit reductions?

Most cost reduction takes something away from someone. Employer payroll tax is one of the few expense lines that can fall without a person losing a job, a benefit, or a service. Nobody’s coverage changes, nobody’s pay is cut, and no position is eliminated. The savings are recurring rather than one time.

Renewal

How do we offset a health insurance renewal increase without cost-shifting to employees?

Mercer’s 2025 survey projects total health benefit cost per employee rising about 6.5 percent in 2026, the steepest increase since 2010. Aon projects 9.5 percent. The usual responses are raising deductibles, raising employee contributions, or narrowing the network, all of which push cost onto staff. A payroll-side restructure creates savings without touching plan design.

Raises

Can we increase employee take-home pay without giving raises?

Enrolled employees typically see roughly $125 more per month in net pay at no cost to them, because the restructure changes how payroll is taxed rather than how much is paid. Payroll cost does not increase. For employers under a wage freeze or a fixed salary pool, it is one of the few compensation levers that does not require new budget.

Legality

Is a FICA savings program legal, and what has the IRS actually said?

The honest answer is that this area is contested and you should not treat it as settled. The IRS addressed fixed-indemnity wellness arrangements in Chief Counsel Advice 202323006, concluding that indemnity payments are taxable wages where the employee has no unreimbursed out-of-pocket medical expense related to the payment. Earlier memoranda reached similar conclusions. The distinction that matters is whether reimbursements are tied to actual qualified medical expenses under Section 105(b) or paid as fixed cash regardless. Have your own counsel and CPA read the plan documents before you decide.

Eligibility

How do we know if our company qualifies?

Three conditions. Employees must be full-time W-2, enrolled in an employer-sponsored group health plan, and participants in Social Security. If your workforce is largely part-time, covered by a union multiemployer fund, classified as 1099 contractors, or outside Social Security, the eligible population will be small or zero. A payroll census answers this precisely in three to five business days.

EBITDA

What does this do to EBITDA, SG&A, and operating margin?

Employer payroll tax, 7.65% of covered wages, sits inside SG&A or within loaded labor cost depending on your chart of accounts, so a reduction flows to operating income and EBITDA. Be realistic about magnitude: it is a modest recurring contribution, not a step change. There is no revenue offset and nothing below the line. For a sponsor-backed company, recurring savings are capitalized at the exit multiple, which is where the number gets interesting.

Payroll

How does this work mechanically on payroll?

It is a second pre-tax deduction under the Section 125 cafeteria plan you already have, paired with a Section 105(b) reimbursement. Most employers already run a premium-only Section 125 that captures FICA on health premiums alone. This layers underneath. Ongoing effort is roughly five to ten minutes per payroll period. No new payroll system, no new carrier contract.

Exclusions

Which employees are excluded?

Part-time and seasonal staff who fall below full-time hours. Employees covered by a union multiemployer or Taft-Hartley fund rather than the company’s own plan. Independent contractors on 1099. And workers in positions outside Social Security coverage, which includes certified staff in many public school districts. That last group is reduced rather than excluded: the employer still pays 1.45% Medicare, so the saving is roughly a fifth of the headline figure. In practice the eligible population is often far smaller than total headcount.

K-12

How does this apply to a school district?

It depends on your district, and you have to check rather than assume. Social Security coverage for public employees comes through Section 218 Agreements between each state and the Social Security Administration, and coverage varies not only between states but within them. The Congressional Research Service notes that teachers in one county may be covered while teachers in a neighboring county are not, because these agreements cover positions rather than individuals. Where certified staff sit in a state retirement system outside Social Security, the employer stops paying the 6.2% Social Security portion but still pays the 1.45% Medicare portion for anyone hired after March 31, 1986. So the saving on those employees is roughly a fifth of the headline figure, not zero, and classified staff (bus drivers, custodians, aides, food service, office staff) remain fully eligible. Ask your business official which positions are covered under your district's Section 218 Agreement before anyone models a number.

Comparison

How is this different from an ICHRA, a PEO, or a level-funded plan?

Those all change your health plan. An ICHRA moves employees to the individual market. A PEO takes over co-employment and payroll. Level funding changes how claims are financed. This changes none of that. It is a payroll-side deduction structure that sits on top of whatever plan you already have, which is why it does not require a renewal cycle or a new carrier relationship.

Timing

When do savings actually begin?

The first payroll cycle after go-live, typically about 30 days from signing. There are no upfront costs. The administrative fee is paid out of savings already captured rather than out of pocket, which is what the zero net cost description refers to.

Nonprofit

Does this work for a nonprofit or association?

Yes, if staff are full-time W-2 on the organization’s own group plan and pay into Social Security. Employees of 501(c)(3) organizations do pay FICA. The savings land in unrestricted funds rather than requiring a program cut, which is the relevant framing when grant or contract revenue is fixed.

ERC

Is this like the Employee Retention Credit?

No. The ERC was a pandemic-era refundable credit and the claim period has closed. This is not a credit, not retroactive, and not a refund. It is a forward-looking change to how payroll is structured. Anyone describing it as similar to ERC is either confused or selling something.

Retention

Can this help with retention in a tight labor market?

It is the honest reason many employers look at it. Employees see a higher net paycheck without the employer increasing payroll. For hourly workforces competing against warehouses, retail, and delivery on wage, that is a real differentiator that does not require board approval or a new salary band. It is not a substitute for competitive pay.

Substantiation

What substantiation does a reimbursement actually require?

This is the first question and everything else follows from it. Treasury Regulation 1.105-2 provides that Section 105(b) does not apply to amounts an employee is entitled to receive irrespective of whether medical expenses are incurred. So ask whether a tax-free reimbursement requires receipts or an explanation of benefits from a qualified provider, or whether it is triggered by participation alone such as completing a survey or using an app. Get the answer from the plan document, not from a person describing the plan document. If the answer is participation alone, that is the structure the IRS addressed adversely.

Circular flow

If the employee takes a pre-tax deduction, how does their take-home pay go up?

A fair and difficult question, and any competent CPA will ask it. A pre-tax deduction normally lowers take-home pay. If take-home rises anyway, money is coming back to the employee, and the tax treatment of that money is the whole issue. In a 2026 review, the law firm Steptoe reported that across the fixed-indemnity wellness proposals it examined, promoters had treated what were properly taxable wages as a tax-free benefit. Ask the plan administrator to walk your CPA through the actual payroll mechanics line by line. If the explanation only works when nobody looks closely at it, you have your answer.

Exposure

If the IRS recharacterized these amounts as wages, what would we owe?

Ask for the number, not the reassurance. Employer FICA is 7.65% of covered wages, 6.2% for Social Security up to the annual wage base plus 1.45% for Medicare with no cap, and the employee side is another 7.65%. In Chief Counsel Advice 202323006 the IRS concluded that payments of this type are subject to federal income tax withholding, FICA, and FUTA. Add failure-to-withhold and failure-to-deposit penalties plus interest, across a three-year audit lookback. Compare that figure to the annual savings. That ratio, rather than the savings alone, is the decision. An employer who has not run that calculation has not evaluated the program.

Standard practice

Why do the large accounting and benefits firms not recommend this?

You should ask this and you deserve a real answer. Steptoe, RSM US, HUB International, and Boutwell Fay have each published cautions on payroll-tax savings programs of this general type. Steptoe's 2026 piece states that its authors are not aware of the IRS having approved any of these arrangements, and notes that promoters commonly supply legal opinions written by their own counsel. Some of that published caution is genuine risk assessment and some is institutional conservatism, and reasonable people read it differently. What I would not accept from anyone is the claim that the establishment simply has not caught on. Ask your own advisors what they think and weigh their answer seriously.

What I do

  • Introduce employers to a third-party plan provider
  • Coordinate a written savings projection from that provider
  • Stay involved as a point of contact through implementation

What I do not do

  • Administer any plan, hold plan funds, or sign employer agreements
  • Determine tax treatment, or provide legal, tax, or accounting advice
  • Sell, solicit, or negotiate insurance. I am not an attorney, CPA, or licensed insurance producer

Read this before you go further

The tax treatment of this kind of plan is contested, and you should not treat it as settled. The exclusion under IRC § 105(b) applies to amounts reimbursing medical expenses an employee actually incurred. Treas. Reg. § 1.105-2 provides that § 105(b) does not apply to amounts an employee is entitled to receive irrespective of whether medical expenses are incurred. The IRS has taken an adverse position on fixed-payment arrangements in CCA 202323006, and a 2023 proposed rule addressing § 105(b) substantiation was deferred rather than withdrawn.

An employer adopting a plan like this should expect that the IRS could challenge it, and should decide, with its own counsel and CPA reading the actual plan documents, whether it is comfortable with that risk. I am telling you this because you deserve to hear it from the person making the introduction, not from an auditor.

How I am paid: if you engage the plan provider, the provider pays me a per-enrolled-employee fee. You pay me nothing. That is a real conflict of interest and you should weigh my enthusiasm accordingly. A written compensation disclosure consistent with ERISA § 408(b)(2) is available on request.
