How do we exit a PEO without breaking payroll?

Why this is harder than arriving

Entering a PEO means handing functions to someone who does them constantly. Leaving means rebuilding those functions inside a company that has, by definition, not performed them for years — and frequently no longer employs anyone who did.

That asymmetry is the whole difficulty. The provider has an offboarding process; what it does not have is your future operating capability, and nobody is responsible for building that but you.

The wage-base question

When employees move between employers with different federal employer identification numbers mid-year, Social Security and FUTA wage bases can restart, meaning the employer pays those taxes again on wages already taxed that year. Across a full workforce this is a material number.

Whether it applies depends on the provider’s certification status and on how the transition is structured, and there are circumstances in which it does not. This is precisely the kind of question to put to your provider and your accountant in writing before setting a date, because the answer can be worth more than every other consideration in the timing decision.

It is also why a January first transition is preferred wherever the calendar permits: a clean year boundary removes the question entirely.

What has to be rebuilt

Payroll under your own FEIN, which means a platform selected, configured and tested. State withholding and unemployment registrations in every state where someone works — some may be dormant rather than absent, some will be new, and all take time. A benefit program: carriers, plans, rates, enrolment, and carrier feeds built and tested. Workers’ compensation underwritten on your own experience, which may be assessed differently outside the pool. And employee data extracted in a form your new systems can use, including historical payroll records you are obliged to retain.

Sequencing that works

Start six months out at minimum. Read the agreement first for notice periods and any data-return obligations. Select and configure the payroll platform early, because everything else depends on it existing. Run state registrations in parallel rather than serially, since lead times differ and none compress. Underwrite workers’ compensation before you need it rather than in the final month. Then parallel payroll, at least two full cycles reconciled to the cent, before the arrangement ends.

Benefits deserve their own track, because a mid-year plan change has employee consequences — deductibles that reset, networks that change, prior authorisations that may not carry. That is a communication project running alongside the technical one.

What people underestimate

The internal capability gap, most of all. Someone has to own payroll operations afterwards, and if nobody in the building has done it, the exit needs a hire or a service relationship decided in advance rather than discovered in month two.

And the historical data. You are obliged to retain payroll records; make their return an explicit part of the exit rather than assuming access continues once the relationship ends.
