Section 125 Software vs Administrator: What Your Company Needs

Section 125 software handles payroll deductions, but the plan document, the summary plan description and the yearly testing are separate jobs. See what each option covers and how to choose.

Quick Answer (as of 2026): Section 125 software processes pre-tax payroll deductions and enrollment. A Section 125 administrator also supplies the written plan document, the summary plan description and nondiscrimination testing support. Software alone leaves those legal tasks with you, so most small and mid-size employers choose an administrator or pair software with one.

Section 125 software and a Section 125 administrator solve different problems. Software moves data. An administrator keeps the plan legal. This page shows what each one covers so you can pick before you spend money on the wrong tool.

What is Section 125 software?

Section 125 software is a tool that tracks employee elections and sends pre-tax deduction amounts to payroll. It may also handle open enrollment screens, life event changes and reports.

The software does one job well: it moves numbers from an employee's election to a paycheck. Software does not decide whether your plan meets the tax code. The tax code asks for more than a deduction code.

What does the tax code require from a Section 125 plan?

A Section 125 cafeteria plan must be a written plan, and it must pass nondiscrimination tests (26 U.S.C. 125). Those two rules are the reason a deduction code in payroll is not a plan.

The tests look at three areas (J.J. Keller Compliance Network, summarizing 26 U.S.C. 125):

  1. Eligibility. The plan cannot favor highly compensated people, and no employee can be made to wait more than 3 years to join.
  2. Contributions and benefits. The plan cannot favor highly compensated participants.
  3. Key employee concentration. Key employees cannot receive more than 25 percent of the total qualified benefits.

If a plan fails, highly compensated or key employees lose the tax exclusion for the affected benefits. Small employers may use the simple cafeteria plan safe harbor if they meet its rules. Our guide to Section 125 nondiscrimination testing explains each test with examples.

Does my company need more than software?

Your company needs more than software if nobody on staff can write the plan document, issue a summary plan description and run the yearly tests. Software covers none of those three tasks by itself.

Check what your current setup leaves out. Summit Health Benefits can review your payroll deductions and tell you which compliance pieces are missing. Schedule a plan review.

Who actually handles the work, Summit or my payroll provider?

Your payroll provider runs the deductions. Summit Health Benefits handles the rest of the Section 125 work. Summit provides the written plan document, the summary plan description and nondiscrimination testing support, and its plan language is reviewed by ERISA attorneys.

That split keeps each party doing what it does best. Payroll applies the deduction code. Summit keeps the plan document and testing current. Your team approves the setup and sends census data. Our implementation timeline shows who owns each step, and most employers go from decision to first deduction in 3 to 6 weeks.

What does it cost to use an administrator instead of software?

Summit Health Benefits charges $35 per enrolled employee per month. Summit takes that fee out of the employer FICA savings the plan creates, so the employer still nets about $56 to $101 per enrolled employee per month. There is no setup fee.

FICA is 7.65 percent per side: 6.2 percent Social Security and 1.45 percent Medicare. The 2026 Social Security wage base is $184,500 (IRS Tax Topic 751, 2026). Pre-tax premiums reduce the wages that FICA applies to, and that reduction funds the fee. Our Section 125 plan cost breakdown shows the full math, and the FICA savings guide explains how the recapture works.

How do I decide between software and an administrator?

Choose software alone only if someone on your team can own the plan document, the summary plan description and the yearly tests. Choose an administrator if no one can, or if you want those tasks off your desk.

Ask these five questions before you decide:

  1. Who writes and updates the plan document each year?
  2. Who issues the summary plan description to employees?
  3. Who runs nondiscrimination testing, and when?
  4. Who answers an employee's life event question on a Tuesday afternoon?
  5. What happens to my plan if our HR manager leaves?

If your answer to any question is "nobody," a tool will not close the gap. A person or a service has to.

What should I check before I sign with any vendor?

Check the scope in writing. Ask the vendor to name, line by line, whether it supplies the plan document, the summary plan description, testing support and attorney review. Ask what is excluded and what costs extra.

Also ask how the fee is set. A fee that rises with each added feature is harder to budget than a flat monthly rate. Our guide to setting up a Section 125 plan walks through the whole sequence, and the Section 125 cafeteria plan guide covers the rules in plain English.

Frequently Asked Questions

What is the best software for a Section 125 cafeteria plan?
The best Section 125 software is the one that fits your payroll system and handles elections, deductions and life event changes. Software alone does not write the plan document or run nondiscrimination testing. Pair it with an administrator if no one on your team owns those tasks.
Do I need a plan administrator for a Section 125 plan?
A Section 125 plan needs someone to maintain the written plan document and run nondiscrimination tests, because the tax code requires both. An employer can do that work in house or hire an administrator. Summit Health Benefits provides the plan document, summary plan description and testing support.
Can payroll software replace a Section 125 plan document?
No. Payroll software applies a deduction code, but a cafeteria plan must be a written plan under 26 U.S.C. 125. Without the written document, pre-tax premium deductions lose their tax basis.
How much does Section 125 administration cost?
Summit Health Benefits charges $35 per enrolled employee per month, paid from the employer FICA savings the plan creates. The employer still nets about $56 to $101 per enrolled employee per month. There is no setup fee.
What happens if a Section 125 plan fails nondiscrimination testing?
If a plan fails the eligibility or contributions test, highly compensated participants lose the tax exclusion for the affected benefits. If it fails the 25 percent key employee test, key employees lose the exclusion. Other employees keep their tax treatment.
How long does it take to set up a Section 125 plan?
Most employers reach the first pre-tax payroll deduction in 3 to 6 weeks after deciding to move forward. The timeline depends on how fast the plan document is finalized and how quickly payroll sets up the deduction codes.
