Cafeteria plan

Note: The HSA is not itself a cafeteria plan benefit – employees cannot receive HSA contributions through salary reductions unless the plan offers an HDHP and explicitly authorizes HSA funding.

Why cafeteria plans matter for enterprise HR

For Benefits Managers and Total Rewards leads at organizations with 1,000 or more employees, cafeteria plans are not optional infrastructure. They are a core mechanism for delivering competitive compensation without proportionally increasing payroll tax obligations.

According to the BLS National Compensation Survey, access to employer-sponsored flexible benefits programs correlates with lower voluntary turnover among professional and managerial workers. SHRM’s 2026 Employee Benefits Survey found that approximately 60% of employers now offer at least one flexible spending account – down from 68% in 2021 – creating a differentiation opportunity for organizations that maintain robust cafeteria plan offerings.

From a compliance standpoint, enterprise HR teams face two distinct obligations. First, the plan must meet IRS Section 125 written plan document requirements. Second, it must pass three annual nondiscrimination tests that prevent highly compensated and key employees from capturing a disproportionate share of tax-advantaged benefits. Failure on either front triggers immediate taxation of benefits for the favored group – a material compliance risk at scale.

The financial stakes are real. For a 2,000-person organization where employees average $3,000 in annual pre-tax benefit elections, a failing nondiscrimination test can convert a significant portion of those elections into fully taxable income for highly compensated participants, generating retroactive tax liability and payroll corrections mid-cycle.

How a cafeteria plan works

The mechanics

Cafeteria plans operate through salary reduction agreements. Employees agree, during open enrollment, to reduce their taxable wages by the amount they wish to direct toward qualifying benefits. Because the deduction occurs before federal income tax and FICA calculations, neither the employee nor the employer pays tax on the redirected amount.

The pre-tax flow works as follows:

1. Employee elects $3,000 in pre-tax health FSA contributions during open enrollment

1. Each paycheck, $115.38 (for a 26-pay-period schedule) is deducted pre-tax
2. The deducted amount reduces the employee’s Box 1 (taxable wages) on their W-2
3. The employer’s FICA obligation is also reduced on that same $3,000

A numerical example of pre-tax savings

Consider an employee earning $60,000 annually who elects $3,000 in pre-tax health insurance premiums under a premium-only plan.

	Without cafeteria plan	With cafeteria plan
Gross wages	$60,000	$60,000
Pre-tax benefit deduction	$0	$3,000
Taxable wages	$60,000	$57,000
Employee FICA (7.65%)	$4,590	$4,361
Federal income tax (22% bracket)	$13,200	$12,540
Total tax liability	$17,790	$16,901
Annual savings	—	$889

The employer also saves $229.50 in FICA contributions on that same $3,000 election. Across 1,000 employees with similar elections, that is $229,500 in annual employer FICA savings – savings that accumulate each plan year without additional benefit spend.

The four types of Section 125 plans

IRS Section 125 authorizes four distinct plan structures. Most enterprise employers operate at least two simultaneously.

1. Premium-only plan (POP)

The simplest and most common structure. Employees pay their share of employer-sponsored health, dental, and vision insurance premiums through pre-tax payroll deductions. No employer contribution is required beyond the plan infrastructure. POP plans are the entry point for most Section 125 implementations – they require minimal administration and deliver immediate FICA savings for both parties.

Best for: Organizations new to Section 125 or those that already offer group health coverage and want to tax-shelter the employee premium share.

2. Flexible spending accounts (FSA)

FSAs allow employees to set aside pre-tax dollars to pay for qualifying out-of-pocket medical expenses (health care FSA, or HCFSA) or dependent care expenses (dependent care FSA, or DCFSA). The health FSA limit for 2026 is $3,400 per employee (IRS Publication 15-B). The dependent care FSA limit is $7,500 per household ($3,750 for married filing separately).

Key FSA mechanics to communicate to employees: the use-it-or-lose-it rule applies, with an optional $660 rollover provision in 2026 or a 2.5-month grace period (but not both). The uniform coverage rule for HCFSAs means the full annual election is available on day one of the plan year – even if the employee has not yet made all their payroll contributions.

Best for: Employees with predictable medical or dependent care costs who can accurately forecast annual spending.

3. Full flex cafeteria plan

The most comprehensive structure. Employers provide a defined flex credit or employer contribution that employees can apply toward any qualifying benefit in the menu – health insurance, FSA, dental, vision, group term life, disability. Employees can also supplement employer credits with their own pre-tax salary reductions. Full flex plans require more robust administration and annual nondiscrimination testing but offer the broadest tax-advantaged benefit selection.

Best for: Large enterprise employers seeking maximum benefit flexibility as a total rewards differentiator.

4. Simple cafeteria plan

Authorized under IRS Section 125(j) for employers with 100 or fewer employees. Simple cafeteria plans must meet a specific eligibility requirement (all employees with at least 1,000 hours of service in the prior year must be eligible) and require minimum employer contributions – 6% of compensation or twice the employee’s salary reduction, whichever is less. In exchange, simple cafeteria plans receive a statutory exemption from the three nondiscrimination tests.

Best for: Small and mid-size employers seeking the administrative safe harbor. Not available to enterprises with 101 or more employees.

Eligible and excluded benefits

What qualifies under Section 125

The following benefits can be offered through a cafeteria plan:

• Employer-sponsored accident and health insurance (medical, dental, vision)
• Health care flexible spending accounts (HCFSA)
• Dependent care flexible spending accounts (DCFSA) – limited to $7,500 per household in 2026
• Group term life insurance up to $50,000 face value
• Accidental death and dismemberment (AD&D) insurance
• Disability insurance (short-term and long-term)
• HSA contributions (employee salary reductions into a qualifying HSA paired with a high-deductible health plan)
• Adoption assistance subject to separate annual limits

What is excluded from a cafeteria plan

Section 125 explicitly prohibits the following from cafeteria plan treatment. Offering these as pre-tax elections is a common compliance error:

• 401(k) elective deferrals and employer matching contributions (governed by IRC Section 401(k), not 125)
• Scholarships and educational assistance programs (IRC Section 117/127)
• Transportation and commuter fringe benefits (IRC Section 132 – these have their own pre-tax treatment but cannot flow through a cafeteria plan)
• Long-term care insurance premiums
• Employee Assistance Programs (EAPs) where the primary benefit is counseling access
• After-tax Roth contributions
• Benefits for non-dependents (with limited exceptions for domestic partners under state law – federal tax treatment of domestic partner coverage remains imputed income under federal tax law)

2026 contribution limits and key thresholds

Benefit	2026 annual limit	Source
Health care FSA (HCFSA)	$3,400 per employee	IRS Publication 15-B
HCFSA rollover (optional)	$660	IRS inflation adjustment
Dependent care FSA (DCFSA)	$7,500 per household	IRC Section 129
DCFSA – married filing separately	$3,750	IRC Section 129
HSA – self-only (paired HDHP)	$4,300	IRS Rev. Proc. 2025
HSA – family (paired HDHP)	$8,550	IRS Rev. Proc. 2025
Group term life insurance exclusion	$50,000 face value	IRC Section 79
HCE compensation threshold	$160,000+	SHRM 2026 Benefit Plan Limits

Note: The HSA is not itself a cafeteria plan benefit – employees cannot receive HSA contributions through salary reductions unless the plan offers an HDHP and explicitly authorizes HSA funding. The cafeteria plan and the HSA are separate legal instruments; the former can facilitate the latter.

Nondiscrimination testing requirements

This is the most frequently misunderstood compliance obligation for enterprise cafeteria plans – and the section most HR glossary pages skip. Every non-simple cafeteria plan must pass three annual tests under IRS Section 125 and Treasury Regulation SS1.125-7.

The three nondiscrimination tests

Test 1 – Eligibility test

The plan must not discriminate in favor of highly compensated individuals (HCIs) as to eligibility to participate. At least 70% of all non-HCI employees must be eligible, or the plan must satisfy an IRS facts-and-circumstances alternative. HCI for this purpose means any employee who was a 5% owner or earned more than $160,000 (2026 threshold) in the prior plan year.

Test 2 – Contributions and benefits test

The benefits available under the plan must not discriminate in favor of HCIs. If the plan offers richer benefit menus, higher employer credits, or more flexible elections to senior or highly paid employees, it fails this test. The IRS examines whether nontaxable benefits provided to HCIs as a percentage of compensation are disproportionate relative to non-HCIs.

Test 3 – Key employee concentration test

The nontaxable benefits received by key employees must not exceed 25% of the total nontaxable benefits provided under the plan to all participants. Key employees are defined under IRC Section 416(i): officers earning more than $220,000, 5% owners, or 1% owners earning more than $150,000.

Consequences of failing nondiscrimination testing

If the plan fails any of the three tests:

• HCIs and key employees lose their pre-tax treatment on benefits elected under the failing test
• Those benefits become taxable income, reportable on the employee’s W-2
• Retroactive tax gross-ups may be required
• The plan sponsor faces potential IRS penalties if testing was not conducted or documented

Failure does not disqualify the plan for non-HCI employees – their benefits retain pre-tax treatment. The consequence is targeted at the favored group.

When to run the tests

Best practice per Newfront’s Section 125 Nondiscrimination Guide is to run a mid-year projection test in Q2 or Q3 and the formal year-end test before the plan year closes. Calendar-year plans should complete testing by November 30 to allow time for corrective actions – removing HCI elections or restructuring benefits – before December 31.

Qualifying events and mid-year election changes

The irrevocability rule

Section 125 plans operate on an irrevocability principle: elections made during open enrollment are binding for the entire plan year. Employees cannot change their benefit elections mid-year simply because their preferences shift. This is the most common employee complaint about cafeteria plans and a frequent source of HR escalations at the start of each calendar year.

Recognized qualifying events

Under IRS Treasury Regulation SS1.125-4, employees may change their cafeteria plan elections mid-year only if they experience a recognized qualifying event AND the election change is consistent with the event:

1. Change in marital status – marriage, divorce, legal separation, annulment

1. Change in number of dependents – birth, adoption, death of a dependent
2. Change in employment status – employee or spouse or dependent gains or loses employment, moves from full-time to part-time, or takes an unpaid leave of absence
3. Change in dependent eligibility – dependent turns 26 (ACA age limit), change in student status, gain or loss of dependent status
4. Change in coverage under another plan – spouse’s employer changes plan during a plan year, or spouse gains or loses coverage elsewhere
5. FMLA leave – employees on FMLA may drop health coverage and re-elect upon return

The 30-day election change window

Most plan documents require employees to submit an election change within 30 days of the qualifying event. Missing this window typically locks the employee in for the remainder of the plan year. HR teams should establish a documented process for receiving, reviewing, and approving or denying mid-year election change requests – both for IRS audit readiness and to manage employee expectations during major life events.

Cafeteria plan vs FSA vs HSA vs HRA

These four terms appear together constantly in benefits conversations and are regularly confused. The table below distinguishes the key dimensions for enterprise HR use:

Dimension	Cafeteria plan (Section 125)	FSA (health care)	HSA	HRA
What it is	Plan structure / legal wrapper	Specific benefit type	Employee-owned savings account	Employer-funded reimbursement account
Who funds it	Employee (salary reduction) and/or employer	Primarily employee	Employee and/or employer	Employer only
IRS code section	Section 125	Section 105/125	Section 223	Section 105
2026 contribution limit	N/A (wraps other limits)	$3,400	$4,300 / $8,550	No federal cap
Rollover at year-end	N/A	Up to $660 (or grace period)	Yes – full balance	Plan-defined
Portability	Not portable	Not portable	Fully portable	Not portable
Requires HDHP?	No	No	Yes	No
Best for	Broad benefit flexibility	Predictable medical costs	Long-term medical savings	Employer-defined reimbursement

An FSA can exist inside a cafeteria plan. An HSA cannot be funded through a cafeteria plan salary reduction unless paired with a qualifying HDHP. An HRA is always employer-funded and cannot receive employee salary reductions – it cannot sit inside a cafeteria plan.

For a deeper comparison, see the flexible spending account (FSA) entry in the Testlify HR Glossary.

What “Cafe 125” means on your W-2

Employees regularly file HR tickets after receiving their W-2 and seeing “Cafe 125” or “125” in Box 14, or noticing their Box 1 wages are lower than their annual salary. Here is the explanation to share with your workforce:

Box 1 (wages, tips, other compensation): Box 1 reflects the employee’s taxable wages after all pre-tax deductions under the cafeteria plan. If an employee earned $60,000 and elected $3,000 in pre-tax health premiums and $1,500 in FSA contributions, Box 1 will show $55,500 – not $60,000. This is correct and expected.

Box 14 (other): Employers may use Box 14 to report additional information. Many payroll systems print “Cafe 125” or “Sec 125” here to document the total cafeteria plan deduction. This is informational only – it does not create additional tax liability. Not all employers populate Box 14 for this purpose, and its absence does not indicate an error.

Box 12, Code DD: Reflects the total cost (employer and employee share combined) of employer-sponsored health coverage. This is a reporting-only line under the ACA – it does not represent taxable income and does not require any entry on the employee’s tax return.

Employee confusion about Box 1 being “wrong” is the most common W-2 ticket driven by cafeteria plan participation. A one-page year-end benefits statement explaining the pre-tax deduction reconciliation eliminates most of these inquiries before they reach HR.

How to set up a Section 125 cafeteria plan

Step 1 – Written plan document requirement

IRS Section 125 requires that every cafeteria plan be maintained under a formal written plan document. The document must specify the plan year, eligible employees, qualifying benefits, election procedures, the irrevocability rule, and COBRA continuation rights where applicable. Verbal or informal arrangements do not qualify. Employers without a written plan document are not operating a cafeteria plan – they are operating a taxable benefit arrangement, and the IRS can assess penalties retroactively during audits.

Step 2 – Define eligible employees and benefits

The plan document must specify which employee classes are eligible (full-time, part-time above a minimum hour threshold, union vs. non-union) and which benefits are offered. New hires typically have a waiting period – often 30 to 90 days – before becoming eligible. Establish these parameters clearly to support nondiscrimination testing projections later in the plan year.

Step 3 – Open enrollment communication

Employees must receive sufficient information before each plan year to make informed elections. Required disclosures under ERISA include a Summary Plan Description (SPD) and Summary of Material Modifications (SMM) when the plan changes materially. For FSA elections specifically, provide a projected expense worksheet to help employees avoid significant year-end forfeitures – a common source of employee dissatisfaction.

Step 4 – Payroll integration and deduction setup

Each pre-tax election must map to a specific payroll deduction code. Confirm that your payroll system (Workday, ADP, or equivalent) reduces Box 1 wages, applies the pre-tax flag correctly for federal and state withholding, and tracks deductions per participant for nondiscrimination testing data pulls. Some states – New Jersey and Pennsylvania notably – do not fully recognize Section 125 pre-tax treatment. Verify state-specific payroll configuration before the plan year begins.

Step 5 – Annual nondiscrimination testing

Run eligibility, contributions/benefits, and key employee concentration tests annually before the close of each plan year. Document results and retain testing records for at least six years per IRS record-keeping guidance. If projections show potential failures, consider increasing employer contributions to non-HCI employees or restricting HCI election maximums before year-end.
