For most of the bill, a nonprofit buys a PEO the same way a company does: the admin fee, health premiums and workers' comp are priced the same way (see how PEO fees and pass-through costs add up). Two tax rules are different, and both affect what the PEO should charge you:

• Federal unemployment tax (FUTA). Service for a 501(c)(3) organization is excluded from FUTA (Internal Revenue Code section 3306(c)(8); see the IRS page "Section 501(c)(3) organizations: FUTA exemption", checked October 17, 2026). For-profit employers pay a net 0.6% on the first $7,000 per employee, or $42 per employee per year (IRS Topic 759). A PEO quote that bundles a single "employer tax" rate may include FUTA you do not owe.
• State unemployment (SUTA). Federal law (section 3309) requires states to let 501(c)(3) employers choose between paying regular SUTA contributions and reimbursing the state for the unemployment benefits actually paid to their former employees. We could not read the statute or an official explainer on our check date; only the title of a US Department of Labor guidance letter on reimbursing employers supports it, so confirm the option with your state agency. Under a PEO, how your account is reported can affect whether you keep that choice.

Reimbursing employer status and the PEO

A reimbursing nonprofit pays nothing to the state UI fund until a former employee collects benefits, then repays those benefits dollar for dollar. A contributory nonprofit pays a rate on each employee's wages up to the state wage base, like any business.

The PEO question is whose account your wages are reported under:

• If the PEO reports under its own state account, your employees' wages go into the PEO's pool at the PEO's rate. That is a contributory arrangement, and your reimbursing election may not apply while you are with the PEO.
• If the PEO reports under your own account, your status and history stay with you. Washington, for example, requires both the PEO and each client to register with the Employment Security Department, and the PEO files client reports within 30 days of each new or ended client plus quarterly reports (RCW 50.12.300).

Some state details that change the math:

Which is cheaper: reimbursing or a PEO's pooled rate?

It depends on turnover. A Missouri nonprofit paying the 1.00% contributory rate on a $9,000 base pays $90 per employee per year. A reimbursing nonprofit with no layoffs pays nothing, but one former employee drawing a full claim can cost more than years of contributions. Under a PEO's pooled account, a layoff does not hit you directly, but you pay the PEO's rate every quarter. Ask the PEO what rate it will bill for your state, whether you can stay reimbursing, and what you will owe for claims that come in after you leave the PEO.

What a PEO costs a nonprofit

No PEO we checked publishes a nonprofit price. The published fees are the same for everyone:

TriNet, Insperity, ADP TotalSource, Paychex PEO and Rippling PEO quote only. The one nonprofit discount in our price research is outside the PEO market: Atlas lists its employer of record service at $399 per employee per month for eligible NGOs and nonprofits, against $599 for others. That is for hires in other countries, not US staff (see PEO vs EOR).

Benefits: the main reason nonprofits look at a PEO

Nonprofits often compete for staff with employers who pay more, so benefits carry weight. A PEO offers large-group health plans and a ready retirement plan. Before you sign, check:

• Retirement plan type. Nonprofits often run a 403(b). PEOs usually offer a 401(k) through the PEO's own plan. The 2026 deferral limit is $24,500 for both (IRS, November 13, 2025). Ask whether you must move your 403(b) assets, and what happens to the plan if you leave the PEO. More in retirement plans for small employers.
• Health credits. Under a certified PEO, the small employer health insurance credit stays with you as the customer (26 USC 3511(d)). Check whether your organization qualifies before you assume the PEO's plan is cheaper.
• FSA administration. TriNet's most common 2026 complaint from worksite employees is rejected FSA claims and repeated proof requests (Trustpilot, July and August 2026). For a mission-driven team, staff experience with the benefits platform matters.

Grant and program reporting

Funders often ask you to show salary costs by grant or program. A PEO's payroll reports are built for companies, so ask before you sign whether you can tag each employee's hours or pay to a program, location or grant code, and export that by pay period. If you use nonprofit accounting software such as Aplos, ask whether the PEO's payroll export maps to your chart of accounts.

If you only need payroll with grant tagging, a payroll service may be enough. Compare in payroll for nonprofits.

PEO, ASO or payroll software

• PEO: you share employer duties and use the PEO's benefits, workers' comp and possibly its state unemployment account. Best fit when you cannot get competitive health quotes on your own.
• ASO: the provider runs payroll, benefits administration and HR, but you stay the only employer. Your own state account, and with it a reimbursing election, stays in place. See PEO vs ASO.
• Payroll software plus a broker: lowest fees ($50 a month plus $8 per employee at Justworks Payroll), full control, your own plans. See the break-even math in PEO vs payroll service.

Questions to ask a PEO before signing

1. Will you bill us FUTA? We are a 501(c)(3). Show the tax lines on the quote.
2. Do you report state unemployment under your account or ours in each of our states? Can we keep our reimbursing election?
3. Who pays unemployment claims from former employees after we leave you?
4. Is the contracting entity on the IRS active CPEO list? Give us its exact name and EIN (check it on our IRS certified PEO list).
5. Can we keep a 403(b), or must we move to your 401(k)?
6. Can payroll be tagged by grant or program and exported?
7. What are the notice period and fees to end the agreement? Most PEOs do not publish them.

Common mistakes

• Accepting a bundled tax rate. If the PEO quotes one percentage for "employer taxes," you may be paying FUTA you do not owe.
• Giving up reimbursing status without noticing. A low-turnover nonprofit can pay more under a PEO's pooled unemployment rate than it ever paid in claims.
• Forgetting claims after you leave. Former employees can file after your PEO contract ends; settle in writing who pays.
• Comparing fees, not plans. In our 10-person example on the PEO cost page, the admin fee was under 12% of the cost on top of salaries; premiums were the larger line. See our PEO rankings for how providers compare.
