Professional Employer Organizations, CPEOs & Third-Party Workforce Relationships
Professional Employer Organizations (PEOs), Certified Professional Employer Organizations (CPEOs), staffing companies, payroll providers, administrative services organizations, and other third-party workforce arrangements present federal tax issues that rarely fit neatly within a single category. Employer status, wage reporting, tax deposits, worker classification, credits and refunds, fringe benefits, and contractual allocations of responsibility frequently overlap.
For PEOs, a single technical or administrative issue may affect multiple clients, large workforces, and many tax periods. The matter must be addressed not only as a legal question, but also as an operational problem involving payroll systems, client data, IRS account administration, and the interests of worksite employees.
Experience With the PEO Industry and the IRS
Fuller Tax Law Group’s PEO practice combines two complementary perspectives with decades of experience.
David Fuller has worked with PEOs and other third-party workforce organizations since 1995.After leaving a leadership role in the IRS National Office branch responsible for these practice areas, David wrote a monthly tax column for PEO Insider on federal tax developments affecting PEOs and their clients. His private-practice experience at Am Law 100 law firms includes planning, compliance, audit defense, administrative appeals, refund claims, and litigation involving payroll taxes and complex workforce relationships.
Before joining the firm, Janine Cook was also a partner at a leading international law firm before then becoming a senior executive in the IRS Office of Chief Counsel. Janine led the National Office functions with technical jurisdiction over employment tax matters for all taxpayers, including PEO and CPEO issues, worker classification, fringe benefits, and federal payroll taxes. In that role, she regularly engaged with NAPEO, PEO industry leaders, IRS operating divisions, and Treasury personnel concerning issues affecting the industry.
This experience affords uncommon insight into the technical rules, the reasons behind IRS positions, the way issues move among IRS functions, and the practical considerations that can determine whether a matter is resolved efficiently or expands into a broader controversy.
PEO and CPEO Tax Planning & Compliance
Proper understanding of the various types of third-party workforce relationships, and structuring and managing the relationships in such a way to achieve the desired result are critical within the PEO industry, both for competitiveness and for minimizing disputes with government agencies such as the IRS. Fuller Tax Law Group can assist with:
- CPEO qualification and ongoing compliance under Sections 3511 and 7705, including covered customers, worksite employees, financial and reporting requirements, and the consequences of suspension or termination.
- Federal employment tax filing and payment structures, including Forms 941 and 940, Forms W-2 and W-3, Schedule R allocations, deposit practices, correction procedures, and account reconciliation.
- Review operational practices to evaluate the allocation of payroll-tax responsibilities and whether the written agreement reflects actual operations.
- Common-law and statutory employer analysis, including control of the payment of wages under Section 3401(d), Section 3504 agent relationships, reporting-agent arrangements, and other third-party payer structures.
- Successor-employer, predecessor-successor, wage-base, common-paymaster, acquisition, client-migration, and employee-transition issues.
- Tax treatment and payroll reporting of employee and executive fringe benefits administered through PEO arrangements, including important safe harbor protections.
Tax Credits, Refunds & IRS Account Resolution
Refundable credits and aggregate payroll filings can produce especially difficult questions for PEOs. A claim may be filed under the PEO’s EIN but depend on client-level eligibility, substantiation, and allocations. Processing delays, offsets, amended returns, Schedule R discrepancies, and IRS account coding may then affect both the PEO and its clients. Fuller Tax Law Group regularly assists with high-dollar matters involving:
- Employment tax refund claims and administrative appeals, including substantiation and procedural strategy.
- Employee Retention Credit matters involving PEO or CPEO filings, client allocations, supplemental claims, audits, erroneous-refund exposure, and responsibility between the PEO and its clients.
- Delayed or misapplied payments, credits, and refunds; transcript and account analysis; and coordination with appropriate IRS functions.
- Information-return and payroll-reporting penalties, reasonable-cause submissions, and penalty-abatement claims.
Worker Classification & Three-Party Relationships
Three-party relationships can complicate the threshold question of who is the employer and which party bears responsibility for federal employment taxes. We advise on the common-law factors, statutory-employer rules, contractual arrangements, and reporting practices that shape that analysis, including:
- Independent-contractor and employee classification reviews and audit defense.
- Section 530 relief and Classification Settlement Program strategies.
- Staffing, payroll-services, ASO, reporting-agent, and Section 3504 agent arrangements.
- Allocation of responsibility among the service provider, client, and related entities.
- Federal tax implications of workforce transfers, reorganizations, acquisitions, and platform conversions.
IRS Examinations, Appeals & Controversies
PEO controversies require early attention to both the substantive issue and the architecture of the examination. Information developed for one client or quarter can quickly be applied across a broader population. We work to define the issue, manage information flow, evaluate available statutory and administrative relief, and prevent a focused inquiry from becoming an unnecessary enterprise-wide dispute.
Our work includes examination strategy, responses to information document requests, technical submissions, meetings with IRS specialists and National Office personnel when appropriate, IRS Appeals, supporting litigation efforts, and coordination with a client’s existing legal and accounting advisors.
With costs rising across the board, we seek to provide all of our guidance efficiently—conserving our clients’ resources while pursuing favorable results. In a number of matters, we have identified refund and tax-saving opportunities that have substantially exceeded our fees, including identifying previously unrecognized multimillion-dollar refund opportunities.
A Focused Role Within the PEO’s Existing Team
Fuller Tax Law Group can serve as primary employment tax counsel or as specialized counsel on a discrete, high-stakes issue. We collaborate with in-house tax and legal departments, payroll and finance professionals, outside counsel, accountants, and other advisors. Our concentrated role is intended to add technical depth and informed IRS perspective without disrupting established relationships. In every client relationship, we seek to provide our services with the highest standards of ethics, integrity, and professional responsibility. Consistent with our prior leadership roles within the IRS National Office, we have earned the respect of IRS personnel for adhering to these standards.
