1,567 companies, a named finance person, a direct line, and a reason

All four things you asked for, from the 5500-SF — the short-form annual return that 97% of small plans file. The trick is the signature block: whoever signs the filing is the company's finance decision maker, and the form also carries the sponsor's own phone number.

Why this beats every list you've had

Judy Diamond sells you the recordkeeper. The OSHA file gave you headcount but almost no phones and zero names. The 5500-SF gives you all three at once — the company, the person who signs for the plan, and the number they filed — plus a compliance answer you can quote back to them.

The 63 best: late employee contributions

Question 10a on the form asks whether the plan failed to transmit participant contributions on time. These 63 answered yes. That's not a filing quirk — late deferrals are treated as a prohibited transaction, and it sits with the company rather than the provider.

Hi, is Dave available? … Dave, this is Kevin Peake from ADP. You signed your 5500 for the plan — the filing answered yes to the late-contributions question, employee deferrals that didn't get into the plan on time. That one's treated as a prohibited transaction rather than paperwork, and it sits with the company, not your provider. Has anyone walked you through the correction?

Note what you get for free here: you can ask for them by name. That alone changes the gatekeeper conversation from "who's calling and what's this about" to "one moment."

The 57 in motion: terminating their plan

Their filing shows a formal resolution to terminate. They're already leaving — so there's no incumbent to displace, just a decision being made right now.

I saw your filing shows a resolution to terminate the plan. If you're moving off it anyway, that's usually the moment worth looking at what payroll and a new plan cost together instead of separately. What's driving the wind-down?

Then 739 with a bond problem, and 693 on size alone

The fidelity-bond rows either report no ERISA bond or one below the required 10% of plan assets. It's a real finding, cheap to fix, and it makes you the person who noticed. The remaining 693 have clean filings — for those you're leading on the fact that they're right in RUN's band and paying for payroll and the plan as two separate relationships.

One thing I caught and fixed, worth knowing about. The first cut of this list had "QIAN LIU" as the controller at seven different companies. Turns out the signature block is often signed by the plan provider's staff, not the client's — Qian Liu signs 407 Bay Area filings, Shirley Horner 304, Marcus Bowie 196. Calling Chelsea Motor Inn and asking for Qian Liu would have made you look ridiculous. So this list only keeps rows where the signer name and the phone number are both unique to that one company — that's what took 3,922 down to 1,567. The names left are genuinely their own people.

Honest limits

The name is the plan signatory, not a verified job title. It's usually the controller, CFO, HR director or owner — the person who owns the finance relationship — but the form doesn't say which. Ask for them by first name and let them tell you what they do.
These all have a 401(k) already. That's what makes them filers. So the door is a takeaway or a consolidation, not a first-plan sale. The no-plan companies are in the OSHA list instead — and that one has almost no phones. The two lists are complements.
Participant count, not employee count. 24–49 plan participants usually means slightly more employees, since not everyone enrols. Close enough for RUN banding, but don't quote it to them as their headcount.
2024 plan year — the most recent complete filing set. A company at 29 last year could be 40 now.
Don't quote penalty amounts or excise-tax rates on the late-contribution rows. Name what the filing says and hand the mechanics to the specialist.
