Questions a CFO Should Ask Before Any Employer-FICA Vendor Conversation

The email or LinkedIn message usually arrives before the checklist does.

A vendor wants to “review payroll taxes and benefits structure.” The deck mentions employer-side FICA. Someone on the leadership team asks whether the conversation is worth having.

What should a CFO ask a company that wants to review payroll taxes and benefits structure before any conversation starts?

That is the purpose of this post. It is a vendor-agnostic due-diligence checklist for CFOs and owners. It applies to every proposer, including System Stream.

For the underlying Section 125 framework, see Reduce Payroll Costs with Section 125. For the broader employer-cost framework, see How Employers Can Reduce Payroll Costs Without Cutting Compensation.

The operating principle is simple: benefits first. Employee value and a compliant structure come first. Any employer-side FICA impact is a consequence of qualified elections that actually reduce FICA wages under the applicable rules.

Checklist first. Conversation second.

Why CFOs need criteria before the first call

Employer FICA is 7.65% of taxable wages, consisting of 6.2% Social Security and 1.45% Medicare.

Once employer-side FICA becomes a conversation topic, the framing matters. Some approaches begin with qualified benefits, plan design, employee value, and protected take-home. Others begin with a savings target and treat benefits primarily as the mechanism for producing it.

Without a fixed set of questions, the CFO is left reacting to each presentation instead of comparing every proposer against the same standard.

Criteria beat brand lists.

If your organization already sponsors a Section 125 plan, that is a separate diligence question. See We Already Have a Section 125 Plan. Why Would Employer-Side FICA Still Be Worth a Look?.

This checklist is about screening the conversation before detailed payroll data is shared or potential savings are socialized internally.

10 questions to ask before any vendor conversation

1. Is employee take-home protected by design?

Ask whether the proposed employer-side impact depends on reducing employee take-home pay.

A benefits-first structure should treat protected take-home as a design requirement, not as optional messaging. If the economics require employees to lose net pay, understand that before going any further.

2. Is there a written Section 125 cafeteria plan?

Ask whether the required written plan exists, whether a new or amended plan would be needed, and when your professional advisors would be able to review the documentation.

The plan document should not be an implementation afterthought.

3. Who is the plan sponsor?

Ask which legal entity sponsors the cafeteria plan, how the proposed structure interacts with your existing benefits arrangement, and whether anything changes regarding sponsorship.

A CFO should know who owns the plan before evaluating the economics surrounding it.

4. How are nondiscrimination testing and related compliance handled?

Ask who is responsible for testing, how eligibility and contribution rules are addressed, and what happens if testing identifies a problem.

Do not settle for “compliance is handled.” Ask who handles it, what is tested, and how issues are addressed.

5. Does our broker stay involved?

Ask whether your existing benefits broker remains involved and how the proposer expects to coordinate with your broker, CPA, and other advisors.

A proper review should complement those relationships, not require you to sideline them.

Your CPA should remain part of the tax and accounting discussion. Your broker should remain part of the benefits discussion. Your payroll provider should remain part of payroll implementation.

6. What is the W-2 headcount screen?

Ask whether the opportunity is designed for employers with 20 or more W-2 employees and how workforce composition affects fit.

Contractor-only models are not a fit.

A proposer should be able to explain why your W-2 population is relevant before requesting detailed payroll information.

7. How are fees structured, and what exactly are we buying?

Ask whether fees are performance-based, retainer-based, fixed, or structured another way.

Then ask the more important question: What exactly is being sold?

Separate the underlying benefit, service, design, administration, or implementation support from the financial consequence of employee elections.

Employer-side FICA movement, if any, follows qualified elections that affect the FICA wage base. It is not a guaranteed financial result that can simply be purchased.

8. How will payroll be configured?

Ask which payroll codes or processes would change, who coordinates the configuration with your payroll provider, how elections move into payroll, and who verifies that the intended treatment has been implemented correctly.

Benefits design and payroll execution eventually have to meet.

If payroll configuration is treated as someone else’s problem later, the implementation risk still belongs to the employer.

9. What happens if employee elections do not materialize at the assumed level?

Ask how the economics change if participation differs from an illustration.

Also ask whether fees change, how employee communication and election support are handled, and which assumptions depend on actual elections.

A projection based on assumed participation should remain an assumption until elections actually occur.

10. If we removed employer FICA from the pitch, would the benefit design still make sense?

This is the benefits-first test.

Temporarily remove the employer-side tax result and examine what remains. Is there a legitimate employee benefit? Is there employee value? Is the structure something the employer would be comfortable explaining to its broker, CPA, payroll provider, employees, and leadership team?

If the entire rationale disappears when the employer-FICA outcome is removed, that deserves additional scrutiny.

For a deeper discussion of this distinction, see How to Tell a Benefits-First Section 125 Structure from a FICA “Savings Scheme”.

Benefits-first signals and savings-scheme red flags

You do not need a list of vendor names to perform an initial screen.

Benefits-first signals include protected employee take-home, clear employee value, written plan documentation, defined plan sponsorship, testing responsibility, coordination with existing professional advisors, a meaningful W-2 fit screen, and a clear explanation of what the employer is actually purchasing.

Red flags include leading almost entirely with tax savings, vague answers about plan documentation or sponsorship, pressure to exclude existing advisors, guarantees, unclear payroll implementation, or economics that depend on reducing employee take-home.

The distinction is not the logo on the presentation. It is the structure behind the presentation.

Use the same questions with every proposer.

When this checklist matters

This checklist is designed for employers with 20 or more W-2 employees evaluating employer-FICA, payroll-tax, or benefits-structure opportunities. Contractor-only models are not a fit.

The objective is not to determine the answer to every technical question before speaking with anyone. It is to determine whether the opportunity has enough structural credibility to justify the next level of diligence.

Before sharing detailed wage data, involving additional executives, or putting potential savings in front of the board, establish the basic facts.

One documented case, not a forecast

One Philadelphia-area home health agency with approximately 160 W-2 employees identified $118,000 in annual employer-side savings without reducing employee take-home pay.

Employer FICA at 7.65%, consisting of 6.2% Social Security and 1.45% Medicare, provides the rate context for employer-side FICA wage analysis.

This is one documented benefits-first case involving a real W-2 workforce. It is not a forecast, a per-employee benchmark, or an indication that another employer will achieve the same result.

Its relevance is narrower: protected employee take-home and employer-side FICA impact can coexist when qualified elections, plan design, employee participation, and payroll treatment align.

Use the checklist before deciding whether to investigate further

A CFO should not need to surrender contact information simply to determine whether an opportunity merits further diligence.

The Employer Workforce Savings calculator provides an initial directional screen using approximate W-2 headcount, without requiring contact information.

Treat the result as a screening tool, not a forecast or substitute for diligence.

If the potential opportunity appears material, the Employer Workforce Savings validation page provides an optional next step after you have applied the checklist.

For additional background, the Section 125 overview and Employer Workforce Savings provide the broader framework.

Throughout the process, keep your broker, CPA, and payroll provider involved. This type of review should complement their roles, not replace them.

Direct answer

Before any employer-FICA, payroll-tax, or benefits-structure vendor conversation, a CFO should establish ten things:

1. Whether employee take-home is protected by design.
2. Whether there is a written Section 125 plan.
3. Who sponsors the plan.
4. How nondiscrimination testing and related compliance are handled.
5. Whether the existing broker stays involved.
6. Whether the employer meets the 20+ W-2 employee fit screen.
7. How fees work and what the employer is actually purchasing.
8. How payroll will be configured.
9. What happens if employee elections do not materialize as assumed.
10. Whether the benefit design still makes sense when employer FICA is removed from the pitch.

Those questions are vendor-agnostic. Ask them of every proposer, including System Stream.

Checklist first. Conversation second.

Estimate your potential Employer Workforce Savings using approximate W-2 headcount. If the initial range warrants further investigation, review the eligibility validation page as an optional next step.
