Premium Only Means Premium Only: What Your Section 125 Plan Won't Cover

Plain English Benefits · Updated September 30, 2026 · Education, not tax advice

Short Answer

A premium only plan covers exactly what the name says: insurance premiums. You can pay for health, dental, and vision insurance with pre-tax dollars, and that's it. You cannot use a premium only plan to set aside money for medical expenses (FSA), daycare costs (dependent care FSA), or HSA contributions. Those benefits require a full cafeteria plan. Most employees never notice the limitation because they weren't planning to use those other benefits anyway, but if you wanted an FSA this year and your employer only offers premium only, you're out of options until next open enrollment.

What Premium Only Actually Covers

The term "premium only" is literal. The plan lets you pay insurance premiums before taxes are calculated. That typically includes:

• Health insurance premiums
• Dental insurance premiums
• Vision insurance premiums

Some plans extend to accident and disability coverage premiums if the employer offers them, but the core idea stays the same: if it's a recurring insurance premium and your employer sponsors the coverage, a premium only plan can make it pre-tax.

What it does not cover, ever, is out-of-pocket spending. A premium only plan has no mechanism to set aside money for copays, prescriptions, glasses, braces, or daycare. Those benefits live in a different part of Section 125, and if your employer didn't set up that part, you don't get access to it.

What Employees Give Up

The limitation matters most when you compare a premium only plan to a full Section 125 cafeteria plan. Here's what a premium only plan excludes:

Health FSA

A health flexible spending account lets you set aside pre-tax money for medical expenses your insurance doesn't cover—copays, prescriptions, dental work, vision care. You decide how much to contribute during open enrollment, the money comes out of each paycheck, and you use it throughout the year.

A premium only plan does not offer this. If your plan is premium only and you need to budget for a known medical expense, you're paying with after-tax dollars.

Dependent Care FSA

A dependent care FSA covers daycare, preschool, before- and after-school care, and summer day camps for kids under 13. The limit is high—up to $5,000 per year for most households, or $7,500 if your employer adopted the recent increase. The tax benefit can be significant for families paying full-time daycare rates.

Premium only plans exclude dependent care FSAs entirely. If you wanted to pay for daycare with pre-tax money, you needed a full cafeteria plan, and if your employer didn't set one up, you're back to paying the daycare center with post-tax income.

HSA Contributions Through Payroll

This one confuses people. You can absolutely have an HSA while you're enrolled in a premium only plan—the two are unrelated. An HSA is paired with a high-deductible health plan, and if you're eligible, you can open one and contribute to it yourself.

But a premium only plan does not let you make HSA contributions through payroll as a pre-tax deduction. Some employers offer that as part of a full cafeteria plan; others handle it outside Section 125 entirely. Either way, if your employer's plan is premium only, HSA payroll contributions are not part of the deal.

You can still contribute to your HSA directly and deduct the contribution on your tax return, so the tax benefit is not lost. You just don't see it show up as a pre-tax payroll deduction the way a cafeteria plan FSA would.

Why Employers Choose Premium Only

Most small employers are not skipping the full cafeteria plan because they're trying to limit benefits. They're choosing premium only because it's simpler.

A premium only plan requires a plan document, employee elections during open enrollment, and annual nondiscrimination testing just like a full cafeteria plan. But the testing burden is lighter when the plan only covers insurance premiums, and there's no FSA balance to track, no midyear reimbursement requests to process, and no year-end forfeitures to reconcile.

For an employer who offers health insurance but does not have the bandwidth to administer an FSA, premium only delivers most of the tax benefit with a fraction of the administrative load. Employees still get pre-tax premiums, which is the largest recurring deduction for most people, and the employer avoids the payroll-tax savings questions that come with more complex cafeteria plans.

The tradeoff is real, but it's a deliberate one. The employer is trading flexibility for simplicity, and in many cases that's the right call.

When Premium Only Is Actually Enough

If you're trying to decide whether your employer's premium only plan is holding you back, the answer depends entirely on whether you would have used the benefits it excludes.

Premium only works fine if:

• You don't have predictable out-of-pocket medical expenses worth budgeting for in an FSA
• You don't pay for daycare, preschool, or other dependent care that would qualify for a dependent care FSA
• You either don't have an HSA or you're comfortable contributing to it outside of payroll

For a large portion of employees, that describes their situation. They're paying insurance premiums and not much else, or their medical spending is too unpredictable to commit to an FSA election in advance. In those cases, a premium only plan delivers the benefit they'd actually use, and the missing FSA options are irrelevant.

But if you're paying $800 a month for daycare, or you know you'll hit a $3,000 deductible this year for a planned surgery, or you wear glasses and need dental work and your kid needs braces, the lack of an FSA is a real cost. You're losing access to a tax benefit you would have used, and the only fix is to ask your employer to upgrade the plan or wait until you work somewhere that offers a full cafeteria plan.

The Upgrade Path

Moving from premium only to a full cafeteria plan is not a mid-year change. Cafeteria plans operate on a plan year, elections happen during open enrollment, and the IRS does not let employees change their FSA elections outside of qualifying events.

If your employer is considering the upgrade, the decision typically happens in the fall before the next plan year starts. The employer would need to adopt a new plan document, decide which benefits to offer (health FSA, dependent care FSA, or both), choose an FSA administrator or handle it in-house, and communicate the new options during open enrollment.

The nondiscrimination testing burden goes up slightly, but it's not a different test—it's the same annual requirement with more elections to include in the calculation. For employers who already run a premium only plan, adding FSA benefits is an incremental step, not a rebuild.

From the employee side, you can raise the question, but the timeline is fixed. If you're asking in March, the answer is "we'll consider it for next year." If you're asking in September and your employer is about to send out open enrollment materials, you might be in time to influence the decision.

How to Know What Your Plan Covers

Your plan document will say "premium only plan" or "POP" in the title if that's what it is. If the document describes FSA options, reimbursement procedures, or a menu of benefits you can choose from, you have a full cafeteria plan, not a premium only plan.

Most employees never see the plan document unless they ask for it. The faster check is your open enrollment materials. If the election form only asks whether you want health, dental, or vision coverage and there's no section for FSA contributions, you're almost certainly looking at a premium only plan.

You can also just ask your HR contact directly: "Is our Section 125 plan premium only, or does it include FSA options?" They'll know, and if they don't, that question will prompt them to check.

FAQ

Can my employer add an FSA to a premium only plan mid-year?

No. Cafeteria plan changes happen at the start of a new plan year, and employee elections are locked in at open enrollment except for qualifying events like marriage, birth, or loss of coverage. If your employer wants to add FSA benefits, the change would take effect January 1 of the following year, assuming the plan year matches the calendar year.

Does premium only mean I can't have an HSA?

No. Premium only refers to what the Section 125 plan covers, and an HSA is separate. If you're enrolled in a high-deductible health plan, you're eligible for an HSA whether your employer's cafeteria plan is premium only or not. The limitation is that you cannot make HSA contributions through payroll as a pre-tax deduction under a premium only plan, but you can contribute directly to your HSA and deduct it on your tax return.

Is premium only better or worse than a full cafeteria plan?

It's simpler, not better. A premium only plan delivers the benefit most employees use—pre-tax insurance premiums—without the administrative load of tracking FSA balances and processing reimbursement claims. For employees who would have used an FSA, it's a lost benefit. For employees who wouldn't, it makes no difference. The right answer depends on your situation and whether your employer has the capacity to run a more complex plan.

Can I opt out of a premium only plan?

You can decline to enroll in employer-sponsored insurance, which would mean you're not using the premium only plan at all. But if you're enrolled in the insurance, the pre-tax treatment is automatic—you don't opt in or out of the Section 125 plan separately. The plan exists to make your premiums pre-tax, and if you're paying premiums, that's what happens.

Running a Plan That Does More?

A premium only plan keeps it simple: insurance premiums, pre-tax, done. If your operation is ready to offer FSA benefits, dependent care accounts, or HSA payroll contributions, that's a full cafeteria plan, and the setup guide at /services/section-125-setup walks through the plan document, the nondiscrimination testing, and the two traps that catch almost everyone—in plain English.
