The July 31, 2026 HR Deadlines Every Small Business Has to Hit

· HR Cadence Hub Team

If you run HR for a Small Business by yourself, you already know July is sneaky. Half the office is on vacation, the building is quiet, and it feels like the slow stretch before fall hiring picks back up. Then the last day of the month shows up carrying more federal paperwork than almost any other date on the calendar.

July 31, 2026 is one of those pile-up days. Three separate federal deadlines land on it, and for some small businesses there's a fourth. They come from different agencies, they have nothing to do with each other, and not one of them sends you a reminder. Miss one and the penalty is real money, not a gentle nudge.

So here's the plain-language version. What's actually due on July 31, who each one applies to, and the quick check that tells you whether you're on the hook. No legalese. Just the list you'd want a friend who's done this a few times to hand you.

Why one date carries three deadlines

There's no grand reason July 31 is so loaded. It's just where a few unrelated rules happen to collide. Quarterly payroll filings always land at the end of the month after a quarter closes, and the second quarter closes June 30. Retirement-plan filings are due seven months after a calendar plan year ends. And this year the government set a hard cutoff for electronic I-9 systems that happens to fall on the very same day.

That's the real trap for a team of one. These don't arrive as one tidy "July 31 to-do." They show up as three separate problems from three separate places, and you're the only person watching all three at once.

Deadline 1: Update your electronic I-9 system

If you onboard new hires with an electronic I-9 system (most HR platforms and onboarding tools handle this for you behind the scenes), it has to be running the current Form I-9 by July 31, 2026.

Here's the background in one breath. The older edition of the form showed an expiration date of 07/31/2026. The current edition shows 05/31/2027. After July 31, any I-9 you complete for a new hire has to be on that current edition, so if your software is still serving the old form, this is the thing to fix this month.

Most vendors push this update automatically, which means your real job is to confirm it actually happened rather than assume it did. Run one test I-9 in your system and check that the form shows the 05/31/2027 expiration date in the corner. If it does, you're set. If it doesn't, open a ticket with your vendor now, because you do not want to discover it's stale on the morning you're trying to onboard someone.

Still run I-9s on paper? Then there's no system to "update," but the same rule applies: any new I-9 you fill out after July 31 has to be the current edition, so pull a fresh copy from the source. We walk through the whole thing in our guide to the electronic I-9 deadline.

Deadline 2: File Form 5500 or 8955-SSA for your retirement plan

Sponsor a 401(k) or another retirement plan on a calendar plan year? Form 5500, the annual return that reports the plan to the Department of Labor and the IRS, is due July 31, 2026 for the 2025 plan year. That's the standard "last day of the seventh month after the plan year ends" rule, and for a December 31 plan year, that day is July 31.

If anyone left during the year with a vested balance still in the plan, Form 8955-SSA is due the same day. Good news if July is already packed: you can get an automatic extension to October 15 by filing Form 5558 before the deadline. Most small plans run through a recordkeeper or third-party administrator who files the 5500 for you, so your task is to confirm they're on it and that their data is right, not to file it yourself.

No retirement plan? Then this one isn't yours to carry. Skip ahead to the next.

Deadline 3: File Form 941 for Q2 payroll taxes

This one is close to universal. If you have employees and run payroll, Form 941 (your quarterly federal payroll tax return) for the second quarter of 2026 is due July 31. It reports the wages you paid from April through June and the federal income tax, Social Security, and Medicare you withheld.

If a payroll provider runs your payroll, they almost certainly file the 941 for you. It's still worth a thirty-second confirmation, especially if you switched providers mid-year or brought payroll in-house, because that's exactly the moment a quarter slips through the cracks. If you file it yourself, set the reminder now and don't let the quiet summer office lull you past it.

The fourth one that catches some small businesses: the PCORI fee

Here's the deadline most solo HR people have never heard of. If you offer a self-insured health plan, a level-funded plan, or a health reimbursement arrangement (an HRA), you owe the PCORI fee, and it's also due July 31, 2026. You report and pay it on Form 720.

It's a small per-person amount ($3.47 or $3.84 per covered life, depending on when your plan year ended), but it's easy to miss because it has nothing to do with the rest of your July paperwork and it only lands on a slice of employers. If your health coverage is fully insured through a carrier, the carrier handles this and you can ignore it. If you're self-insured or run an HRA, add it to the list.

How to keep July 31 from sneaking up again

You don't need a compliance department to stay ahead of a day like this. You need the dates living somewhere other than your own memory. The reason these deadlines bite teams of one isn't that they're hard. It's that nobody surfaces them until they're already late, and a spreadsheet doesn't nudge you.

That's exactly why we built the free 2026 HR Compliance Calendar. It maps the federal and state dates to the month they actually land (July 31 included, with all of these on it), so you can drop them into whatever calendar you already live in and stop holding them in your head. Grab it once, and the next pile-up day stops being a surprise.

While you're thinking in deadlines, mid-summer is also a sensible time for a quick once-over of the rest of your HR house. Our mid-year HR audit checklist is built for exactly that. If you'd rather handle the tracking with tools that don't cost anything, here's our honest roundup of free HR tools for a Small Business. And for the bigger picture on running compliance as a steady rhythm instead of a string of last-minute scrambles, here's how to build an HR compliance calendar when you're a team of one.

FAQ

What HR deadlines fall on July 31, 2026? Three land on almost every small business's radar: the deadline for electronic I-9 systems to be on the current Form I-9 (the edition showing a 05/31/2027 expiration), Form 5500 (or Form 8955-SSA) for calendar-year retirement plans, and Form 941 for second-quarter payroll taxes. A fourth, the PCORI fee on Form 720, applies if you offer a self-insured plan, a level-funded plan, or an HRA.

Do I have to update my I-9 system by July 31, 2026? If you use an electronic I-9 system, yes. It needs to serve the current Form I-9 (showing the 05/31/2027 expiration date) for any new hire after July 31, 2026. Most vendors push the update automatically, so the practical step is to confirm it happened by running a test I-9. If you complete I-9s on paper, there's no system to update, but new forms after that date still have to be the current edition.

When is Form 941 for Q2 2026 due? July 31, 2026. Form 941 is the quarterly federal payroll tax return, and the second quarter (April through June) is always due by the last day of the following month. If a payroll provider files it for you, confirm it's covered, particularly if you changed providers this year.

When is the Form 5500 deadline for 2026? For a calendar-year plan (one that runs January 1 to December 31), Form 5500 for the 2025 plan year is due July 31, 2026, which is the last day of the seventh month after the plan year ends. You can file Form 5558 by that date for an automatic extension to October 15, 2026.

What is the PCORI fee and when is it due in 2026? The PCORI fee funds patient-centered outcomes research and is paid on Form 720 by July 31, 2026 for plan years that ended in 2025. It applies to self-insured health plans, level-funded plans, and HRAs, at $3.47 or $3.84 per covered life depending on when the plan year ended. If your coverage is fully insured, your carrier handles it.
