Form 5500 Extended Deadline: What Happens If You File for an Extension

You filed Form 5558 back in July and felt a big weight lift off your shoulders. Now October 15 is creeping up, and your Form 5500 still isn't done. Sound familiar? You're not alone. Plenty of busy owners go through this problem every fall.

This guide breaks down the Form 5500 extended deadline in plain English. You'll learn what is really due, who has to file, and what happens if you miss it. We'll also show you how this date lines up with your Summary Annual Report deadline.

What Is the Form 5500 Extended Deadline?

Form 5500 is the yearly report for your employee benefit plans. It falls under ERISA, the federal law that sets the rules for these plans. That's why many people call it the ERISA annual report. For a calendar-year plan, the normal due date is July 31. That's seven months after the plan year ends. 

When you filed the Form 5558 extension, you bought an extra two and a half months to file it. That means for the 2025 plan year, your Form 5500 extended deadline is now October 15, 2026. 

Important note: October 15 fits calendar-year plans. If your plan year runs on a different schedule, your dates will be different too. So, remember to check your plan year before you stick to that date.

What's Actually Due on October 15?

Form 5558 only gave you more time. It didn't actually file anything. Form 5500 is still due by October 15, and needs to be filed online through the Department of Labor's EFAST2 system. 

Also, don't count on a second extension. Form 5558 works one time for each filing, so sending another request won't extend the date again. That's true for any Form 5500 filing extension small business owners request, no matter how few people are on the team.

Who Needs to File Form 5500?

Not every business has to file this form. Here's a simple way to find out if you need to:

• You generally have to file if your plan had 100 or more participants on the first day of the plan year.
• You also have to file if your plan is funded through a trust, even if the plan is small.

Many employee benefits count here, not just health insurance. Medical, dental, vision, life, and disability plans can all be part of it. Flexible spending accounts (FSAs) and health reimbursement arrangements (HRAs) are included as well.

How to Count Participants

You need to count your covered employees, former employees who kept coverage through COBRA, and covered retirees. You do not need to count spouses and kids. 

Also, make sure to use the headcount from the first day of the plan year, and not today's roster.

Who Can Skip the Form 5500?

Smaller plans with fewer than 100 participants are usually off the hook if the benefits are fully insured or paid from company funds. If you bundle several benefits into one wrap plan, you typically file just one Form 5500 for the whole bundle.

If your team has grown fast this year, double-check your numbers. A startup can cross the 100 mark quicker than you think.

Form 5500 Late Filing Penalties

The Department of Labor (DOL) can charge up to $2,739 per day for missing the Form 5500 extended deadline or an incomplete Form 5500. 

The law doesn't set a cap on that total. This means that just thirty days late could quickly add up to over $82,000 in penalty fees! In real life, the DOL has some say in the final amount, but it’s best not to take that chance with your business.

Notice that incomplete forms also face penalties. A rushed form with missing pieces can cause trouble just like a late one.

Already Late? There's a Fix (The DFVCP)

Don't panic. The Delinquent Filer Voluntary Compliance Program, or DFVCP, is the DOL's own safety net for late filers. It lets you turn in an overdue Form 5500 and pay a much smaller penalty, which can be a lifesaver for businesses that catch a mistake late. 

Here's the catch: You have to file through this program before the DOL sends you a written notice about the missed Form 5500 filing. If you receive this notice, you won’t be eligible to use the DFVCP

Reduced Penalties Under the Delinquent Filer Voluntary Compliance Program

Under the DFVCP, the basic penalty is $10 per day. Each filing also has a cap, and the cap depends on the size of your plan:

• Large plans (100 or more participants): $2,000 per late year, and $4,000 per plan if more than one year is late.
• Small plans (fewer than 100 participants): $750 per late year, and $1,500 per plan if more than one year is late.

Two Important Things to Know About the DFVCP

1. If you miss the Form 5500 extended deadline (October 15), the clock starts counting from your original July 31 due date, not from October 15.
2. The program only covers the DOL's late-filing penalties. It doesn't wipe out every penalty, and it won't settle anything the IRS may charge on its own.

How the SAR Deadline Fits In

Your Summary Annual Report, or SAR, runs on a related timeline. It's the short, plain-English version of your Form 5500 that goes out to your plan participants. Normally it's due September 30, but because you extended the 5500, your SAR deadline moves out to about December 15.

That gives you a little breathing room, but only if your Form 5500 gets filed first. Our post on what is a summary annual report explains what goes in the SAR, who gets a copy, and how to hand it out the right way.

A Checklist for the Form 5500 Extended Deadline

It’s best to set your own finish line a week before the real one. That way, a mistake doesn't turn into a penalty. Here are the things you need to do:

1. Check your Form 5558 record: Make sure the form lists the right company, plan number, and plan year. Your Form 5500 should match this.
2. Request carrier details: Ask your insurance carriers for their contract details, such as policy numbers, dates, premiums, and commissions. These numbers go on the form. Make sure to put this in writing, and request in advance since carriers can take a while to answer.
3. Confirm your participant count: Check your participant counts against the right date, and not this month's roster. The first day of the plan year decides whether you have to file at all.
4. Assign the filing: Decide who reviews, signs, and submits the form, and make sure their online EFAST2 access works. Test the login early so a password problem doesn't eat up your last day.
5. Keep your records: Save your filing confirmation and keep your records. According to ERISA, you need to keep these documents for at least six years. That includes the papers you used to prepare the form.

Also, the form should match the 2025 plan year. Your newest renewal paperwork may not tell the right story for last year's benefits.

Ready to File Form 5500 Before the Extended Deadline?

Your Form 5558 extension gave you time, but the Form 5500 itself still has to be filed by October 15. Whether you run a growing shop in Kansas or a startup in Missouri, compliance often lands on your desk, and you already have a business to run.

Benefits Made Great is the benefits broker that can help you keep these dates in view all year, not just at renewal. Call us today at (913) 243-3412, and let's get this form filed before the deadline.
