Worker Classification Impacts Retirement Plans for Contractor Businesses

May 7, 2026

Construction and contractor businesses often operate with highly dynamic workforces, using seasonal or project-based hires, independent contractors, and the like. The flexibility required in these types of companies—while essential to project-based work—can create significant retirement plan compliance risks. 


From a retirement plan perspective, these workforce characteristics require careful oversight, as even small administrative inconsistencies can lead to costly compliance failures over time. 

Classification Risks: Independent Contractor vs. Employee 


While worker classification is often viewed primarily as a tax issue, it’s actually one of the most significant retirement plan compliance challenges for contractor businesses.  Distinguishing between independent contractors and employees has direct implications for plan eligibility and compliance. 


If individuals classified as 1099 independent contractors are later reclassified as employees—whether as a result of an internal review or because of an IRS determination—retirement plan issues tend to arise retroactively. That’s because those individuals may have been previously excluded incorrectly from participating in the plan, creating a need for some type of corrective action. 


In these situations, employers may be required to make corrections called missed deferral opportunities (MDOs); make payments foremployer contribution liabilities; and complete IRS compliance documentation. These actions can be both administratively burdensome and financially significant, particularly if misclassifications span multiple years. 


To minimize this long-term risk, proactively reviewing worker classification (at least once a year) and coordinating that analysis with your retirement plan administrator are critical. 


Dealing with High Turnover and Tracking Re-hires 


Contractor businesses often experience high workforce turnover, with employees departing and re-entering based on the flow of projects. This pattern introduces additional complexity for the purposes of retirement plan administration, specifically in terms of tracking prior service. 


What do we mean by this? If rehires’ prior service hours are not properly tracked and credited, errors may occur in determining plan eligibility and vesting. For example, a re-hired employee, who satisfied eligibility requirements when they worked previously, may now be incorrectly treated as a brand new hire, delaying plan re-entry or under-calculating benefits. 


These types of errors can create the need for compliance corrections (either through government fix-it programs or by reworking a Plan document) and increased scrutiny during a retirement plan audit, not to mention participant dissatisfaction. 


Implementing consistent rehire tracking processes and maintaining accurate historical employment records are essential components of effective retirement plan administration in this environment. 


Timing of Plan Contributions in Fast-Paced Payroll Cycles 


Another key area of risk for contractor businesses is the timing of deposits of employee deferrals. With project-based pay schedules creating frequent payroll cycles,there is an increased need to monitor the timely remittance of employee retirement plan contributions. 


Why? Because Department of Labor (DOL) regulations require that employee deferrals be deposited as soon as administratively feasible. Delays beyond this standard can result in prohibited transactions (for example, creating a loan from the plan to the employer, which isn’t allowed), required corrective contributions, and potential costly penalties. 


Due to the volume and frequency of payroll activity in the contractor industry, even minor process breakdowns can lead to recurring issues if not proactively addressed. 


Controlled Group and Multi-Entity Considerations and Their Impact on Plan Compliance 


Many contractor and construction businesses operate through multiple related entities, whether for liability protection, project segmentation, or tax planning purposes. However, when ownership overlaps (i.e. when multiple businesses are owned by the same entities), the IRS may treat those entities as a single employer under something called “controlled group” rules. Under these rules, employees of any related entities must all be considered together for retirement plan coverage and nondiscrimination testing purposes. Failure to properly account for controlled group status can result in testing failures, missed eligibility, and incorrect contribution allocations. 


When these issues surface (often during annual testing), the fixes are rarely painless: 


  • Owners may have to take plan contributions back (and lose expected tax benefits) 
  • Employers may need to make additional contributions to staff to correct imbalances 
  • Corrections can require recalculations and reallocation of contributions, sometimes going back multiple years 
  • Administrative costs and potential penalties can follow if not handled properlyIn other words, what looks like a technical oversight can quickly turn into a cash flow issue. 


Why Construction Businesses Are Especially Exposed 


This compliance risk related to controlled groups tends to be higher in construction and contractor businesses because: 


  • It’s common to have multiple LLCs across projects or ownership groups 
  • Payroll and operations are often decentralized 
  • Different entities may work with different plan providers or advisors 

This combination makes it easy for one entity to operate in a silo—without realizing it’s part of a larger compliance picture. 


When payroll, ownership, and retirement plans aren’t aligned across entities, employees may be unintentionally excluded from plan participation, contributions may be misallocated, and testing results may not reflect reality. These problems often go unnoticed until year-end testing—or worse, an audit—when they become more expensive and disruptive to fix. 


The Bottom Line: You Can Strengthen Retirement Plan Compliance If You Have a Contractor or Construction Business 


As we explained above, contractor businesses benefit from a retirement plan administration approach specifically designed to address the workforce fluidity and operational complexity inherent to the industry. Without structured oversight, the natural variability of a contractor workforce can create ongoing plan compliance instability. Over time, these risks can compound, leading to costly corrections, regulatory scrutiny, and operational disruption. 


By aligning retirement plan processes with workforce realities, contractor businesses support a more stable and effective retirement plan framework.

The Challenge Sometimes the most expensive retirement plan mistakes aren't dramatic. They're quiet. A former client of ours changed retirement plan providers following an acquisition several years prior. On the surface, everything appeared to be operating normally after moving to the new provider: employees continued making contributions to the plan, the plan’s investments remained in place, and the business continued its normal operations. Then another merger opportunity came along. As part of their due diligence process, the buyers reviewed the retirement plan. What they found immediately raised concerns. The annual Form 5500 filings required by ERISA law had not been submitted for several years. That also meant that none of the required compliance testing had been completed, and routine administrative responsibilities had also gone undone. What had started as a routine review quickly became a significant obstacle to completing the business sale. The Hidden Risk Many employers assume that once a retirement plan provider is hired, responsibility for the plan’s ongoing administration has effectively been transferred to that provider. But a plan sponsor is never completely relieved of its responsibility to oversee the plan. Even when outside providers are hired to handle filings, testing, recordkeeping, or other administrative functions, the employer still needs to make sure those responsibilities are being fulfilled. At the same time, there is an important difference between a provider that simply waits for the employer to supply information and one that actively works with the employer to make sure the plan stays on track. In this case, some of the missing work may have resulted from information requested by the provider that was never supplied by the employer. Technically, the employer still had a responsibility to provide that information and ensure the work was completed. But years of required administration should not quietly disappear into a communication gap. A proactive administrator follows up. If the usual contact isn’t responding, they escalate the issue. They make sure the appropriate people understand what is outstanding, why it matters, and what could happen if it isn’t addressed. Retirement plans require ongoing attention every year, including government filings, compliance testing, participant administration, documentation, and, when necessary, operational corrections. When those responsibilities are neglected, the consequences may not become obvious immediately. Instead, problems can accumulate quietly in the background until an IRS inquiry, Department of Labor investigation, audit, or—as in this case—a business transaction suddenly exposes years of unresolved issues. The prospective buyer made it clear that the retirement plan issues needed to be addressed before the transaction could move forward. The Rescue Knowing we had previously administered their plan, the current company leadership contacted us. Our first step was to determine the full scope of the problem. The timing made the situation particularly challenging. This wasn’t simply a retirement plan cleanup project. A business transaction was underway, and the company needed answers quickly. We assembled a team to determine the full scope of the problem and begin developing a path forward. Because we have deep experience with taking over neglected plans, we were able to separate perceived problems from actual compliance issues and reconstruct the plan's history. In reviewing the prior documentation, we identified exactly which administrative functions had been completed and which had been missed. We gathered historical payroll and participant data and developed a comprehensive correction strategy. Having access to historical plan records was especially important. Retirement plan problems may not surface until years after the underlying event, making good record retention critical. If you’re curious about how long to hold onto plan documentation, please see our blog post here . The final correction effort proved to be far more manageable than originally feared. Instead of allowing uncertainty around the retirement plan to continue hanging over the transaction, the employer now understood what had actually gone wrong, what needed to be corrected, and what steps were required to move forward. The Outcome With the correction efforts clarified and a clear roadmap in place, the employer was able to begin correcting the plan and continue moving toward its business transaction. More importantly, the company avoided entering the acquisition process with unresolved retirement plan liabilities hanging over or ruining the deal. The experience also reinforced an important lesson: Changing retirement plan providers doesn't eliminate administrative responsibilities. But it also demonstrated why the quality of the administrator matters. A good retirement plan administrator doesn’t simply process the information that arrives. They help make sure the information arrives in the first place. The Lesson: Oversight Is a Shared Process Employers ultimately have a responsibility to oversee their retirement plans, even when they hire professionals to handle much of the day-to-day work. That doesn’t mean the employer should have to become a retirement plan expert or personally track every filing deadline and compliance requirement. That’s one of the reasons experienced administration matters. A proactive provider should help keep the employer informed, identify missing information, follow up when something is outstanding, and escalate issues before a missed request becomes a missed filing—or several years of missed filings. The cost of failing to do so can extend well beyond an annual administration fee: Missed filings and potential penalties Incomplete compliance testing Corrective work Additional professional fees Delayed business transactions Uncertainty during mergers and acquisitions  By the time those costs appear, they can far exceed whatever might have been saved by choosing a lower-cost service model. That’s why retirement plan administration shouldn’t simply be viewed as paperwork. It should be viewed as an ongoing partnership in managing risk.

The Challenge A business owner came to us after receiving confusing news from their retirement plan actuary. Their Defined Benefit (Cash Balance) Plan had performed exceptionally well over several years; strong investment returns seemed to have created what’s called an overfunded Plan. While it seems like a positive name, an overfunded plan can create excessive and unexpected tax liabilities. So, their actuary recommended terminating the Plan by transferring the excess assets into the company's other Plan, a 401(k)/Profit Sharing Plan, before eventually closing both Plans, a lengthy and complicated process.

As we wrap up the second quarter of 2026, one trend continues to stand out: retirement plans are becoming increasingly specialized. Whether driven by changing regulations, unique workforce structures, or evolving business goals, employers are finding that a one-size-fits-all approach simply doesn't work. This quarter, we explored the unique retirement plan challenges facing several industries—including medical and dental practices, construction companies, architecture and design firms, wineries, and California employers navigating CalSavers requirements. We also continued our series on the hidden risks of low-quality retirement plan services, highlighting how operational complexity, fragmented accountability, and misaligned incentives can create costs that extend far beyond administrative fees. For employers still evaluating their retirement plan options, we also discussed opportunities that many business owners overlook, including the ability to establish retirement plans after filing a tax extension and potentially generate meaningful tax savings. Below is a recap of the articles we published this quarter. We hope they provide practical insights to help you reduce risk, improve plan performance, and make more informed retirement plan decisions.
