Compliance & Fiduciary Strategy

Form 5500 Season: What Your July 31 Deadline Actually Means for Your Fiduciary Duty

Ethos Benefits  |  July 2026

You’ve probably already circled July 31 on the calendar. For most calendar-year retirement and health plans, that’s the day your Form 5500 is due to the Department of Labor. It’s easy to treat this as one more box on the compliance checklist, hand it to your recordkeeper or TPA, and move on. But the Form 5500 deadline is really a checkpoint on something bigger: whether you, as plan sponsor, are living up to the fiduciary duty you signed up for the moment you started offering a retirement or health plan.

What’s Actually Due on July 31

If your retirement or health and welfare plan runs on a calendar year, your Form 5500 annual return is due the last day of the seventh month after the plan year ends, which lands on July 31, 2026 this year. The form, along with its schedules and attachments, has to be filed electronically through the DOL’s EFAST2 system. Depending on plan size, you’ll file the full Form 5500, the Form 5500-SF for plans with fewer than 100 participants, or the Form 5500-EZ for one-participant plans.

This filing isn’t just an administrative formality. It’s the government’s primary window into how your plan is run, who’s covered, what it costs, and whether the money is being handled the way ERISA requires. That’s exactly why it deserves more attention than a quick sign-off.

This Isn’t Just a Filing. It’s a Fiduciary Checkpoint.

Every decision maker attached to a retirement or health plan, including you, is filtered through one question under ERISA: is this decision truly in the best interest of the people who depend on it? That’s the fiduciary standard, and it doesn’t take a vacation just because the form got filed on time. Plan sponsors are responding to heightened fiduciary risk right now, and NAPA-Net’s coverage of the rising ERISA litigation environment makes the point plainly: filing accurately and on time is table stakes, not the finish line.

When you pull together the data for Form 5500, you’re already looking at plan expenses, service provider fees, participant counts, and investment performance. That’s the same information a real fiduciary review needs. Treating the deadline as a strategy moment instead of a paperwork chore means using this data pull to ask sharper questions: are your recordkeeping and administrative fees reasonable? Is your investment lineup still serving participants well? Are your plan documents current with the latest regulatory changes? The filing gives you the raw material. The fiduciary duty is what you do with it.

None of this requires a forensic audit. It just requires asking the right questions in the right order, and writing down the answers somewhere you can point to later if a participant, an auditor, or your own future self asks how you arrived at them. Use these four checkpoints as your starting point for that conversation with your recordkeeper, TPA, or advisor.

If You Need More Time: Form 5558

Sometimes July 31 arrives before your data is clean or your service providers have finished their piece. That’s what Form 5558 is for. Filing IRS Form 5558 on or before your original due date buys you an automatic two-and-a-half month extension, pushing calendar-year plans to October 15, 2026. A few things worth knowing before you lean on it:

• The extension has to be requested by the original deadline. There’s no filing it late.
• If you sponsor more than one plan, each plan needs its own Form 5558. There’s no bundling.
• Form 5558 can now be filed electronically through EFAST2 or on paper, whichever your process supports.

An extension isn’t a workaround for disorganization. It’s a tool, and a good one, for making sure the filing you submit is accurate rather than rushed. Real fiduciary care sometimes means slowing down to get it right.

What It Costs to Get This Wrong

The penalties for missing the deadline entirely are steep, and they can stack from two different regulators at once.

According to the Department of Labor’s Federal Register notice on 2026 civil penalty adjustments, the DOL can assess up to $2,739 per day with no ceiling for a late or incomplete Form 5500. Separately, the IRS layers on its own penalty of $250 per day, capped at $150,000 per plan year. Miss the deadline and you could be facing both regulators at once.

If you do fall behind, the DOL’s Delinquent Filer Voluntary Compliance Program offers a real path back. Filing voluntarily before the DOL sends a notice caps the penalty at $10 per day, up to $2,000 per plan per year, or $4,000 for multiple years of delinquent filings. It’s a meaningful reduction, but it only works if you catch the problem before the DOL does.

Turn the Deadline Into a Strategy Moment

You’ve built strategy into nearly every other part of your business. Benefits compliance shouldn’t be the one area that runs on autopilot until a deadline forces attention. SHRM’s guidance on Form 5500 frames the filing as an annual checkpoint on plan health, and that’s the right instinct. The real opportunity is using this moment to ask whether your plan design, your fees, and your provider relationships still serve your people the way they should.

That’s where a real fiduciary approach pays off. Instead of a once-a-year scramble to get a form filed, you build a rhythm of reviewing plan performance, benchmarking costs, and keeping documentation current, so that July 31 becomes confirmation of work already done well, not a deadline you’re racing.

You’ve managed every other part of your business with strategy. Benefits shouldn’t be the one area that beats you every year.

Frequently Asked Questions About Form 5500

What is Form 5500, and who actually has to file it?

Form 5500 is the annual report that ERISA-covered employee benefit plans file with the Department of Labor, IRS, and Pension Benefit Guaranty Corporation. If you sponsor a retirement plan like a 401(k), or a health and welfare plan such as group health, dental, or vision coverage with enough participants, you’re on the hook for it. Fully insured health plans with fewer than 100 participants at the start of the plan year are typically exempt, but retirement plans generally have to file regardless of size, just on a different version of the form.

What’s the difference between Form 5500, Form 5500-SF, and Form 5500-EZ?

The standard Form 5500 is built for larger plans. Form 5500-SF is a shorter version for plans with fewer than 100 participants at the start of the plan year. Form 5500-EZ is for “one-participant” plans, meaning plans that cover only a business owner, the owner and a spouse, or partners and their spouses, with no other employees. Which version you file depends on your plan’s size and structure, not on how big your company is overall.

What happens if I file Form 5500 late?

Two regulators can penalize you separately, and neither penalty cancels out the other. The DOL can assess up to $2,739 per day with no cap for 2026 filings, and the IRS layers on its own penalty of $250 per day, capped at $150,000 per plan year. Missing the deadline doesn’t just risk one fine, it risks both at once, which is exactly why treating July 31 as an afterthought is a costly habit to break.

Is there a way to reduce the penalty if I’ve already missed a filing?

Yes. The DOL’s Delinquent Filer Voluntary Compliance Program lets you self-correct before the DOL sends a notice. Under DFVCP, the penalty drops to $10 per day per missed filing, capped at $2,000 per plan per year, or $4,000 for multiple years of delinquent filings. It only works if you come forward first, so the earlier you catch a missed filing, the better your outcome.

Does Form 5500 apply to health and welfare plans, or just retirement plans?

Both. Most people associate Form 5500 with 401(k)s, but ERISA-covered health and welfare plans, including group health, dental, vision, life, and disability plans, are subject to the same filing requirement once they cross the participant threshold. If you sponsor multiple plans, each one may need its own filing, which is worth confirming with your TPA or broker well before the deadline.

Should I file Form 5558 even if I think I’ll make the July 31 deadline?

It doesn’t hurt to have the option in your back pocket. Filing Form 5558 before the original due date is what preserves your right to the extension, so if your data isn’t fully reconciled as July 31 approaches, filing for the extension buys you until October 15 without triggering a penalty. Treat it as an insurance policy for your timeline, not an admission that something’s wrong with your plan.
