What Every HR Manager Needs to Know About ERISA

If you manage HR, you’ve probably heard of ERISA, the Employee Retirement Income Security Act. But even experienced professionals sometimes underestimate how much it shapes everyday benefits administration. From health plans to 401(k)s, ERISA is everywhere. Understanding it, and finding the right support, can save your organization from fines, lawsuits, or worse.


Think of ERISA as a framework that protects employees while keeping your company compliant. Here’s what every HR manager should know, with practical tips for avoiding common pitfalls and how Ameriflex can help.

1. ERISA Covers More Than Retirement Plans

Many assume ERISA only applies to retirement plans. Not true. It covers most private-sector benefit plans, including:

  • Health, dental, and vision insurance
  • Disability and life insurance
  • Retirement plans like 401(k)s

Even small perks, like paying employee medical premiums or offering short-term disability, can trigger ERISA requirements.

Example: A company introduces a short-term disability benefit without realizing it qualifies as an ERISA plan. Because no plan document is created, they miss required documentation deadlines.

Avoid headaches: Treat every benefit as a potential ERISA plan. Document it, track it, and make sure you understand your obligations. Ameriflex can help identify which benefits fall under ERISA and keep documentation up to date.

2. You Might Be a Fiduciary

Here’s a surprise for many HR managers: if you make decisions about benefits plans, you may be considered a fiduciary under ERISA. That means you must:

  • Act in the best interest of participants
  • Make prudent, documented decisions
  • Follow plan documents
  • Monitor fees and providers

Failing to meet fiduciary duties can lead to personal liability. 

Example: A small company selects a retirement plan vendor without reviewing or benchmarking fees. Years later, they discover employees have been paying excessive costs, drawing regulatory attention.

Avoid headaches: Identify fiduciaries formally, provide training, and document decisions. Fiduciary liability insurance helps, and Ameriflex partners with HR teams to reduce personal and organizational risk.

3. Documentation Is Non-Negotiable

Every ERISA plan needs a formal plan document and a Summary Plan Description (SPD). Missing or outdated documents can be costly. Other requirements include:

  • Form 5500 (for larger plans)
  • Annual notices
  • Benefit statements

Example: An HR team adds a wellness stipend to its benefit offerings but doesn’t update its SPD. When an employee asks for plan details, the company cannot provide compliant documentation—creating unnecessary risk.

Avoid headaches: Treat documentation as a living system. Update it with every change and maintain a compliance calendar. Ameriflex makes it simple to manage ERISA-required SPDs and Wrap documents, helping employers file all benefits in one Form 5500.

4. Claims and Appeals Require Clear Processes

ERISA requires employers to have fair claims and appeals procedures. Health plan denials, in particular, must include detailed explanations and strict timelines.

Example: A claim denial letter lacks the required details, leaving an employee confused and delaying their appeal. This not only frustrates the employee but also exposes the employer to compliance risks.

Avoid headaches: Establish a transparent, well-documented process for claims, train your team, and rely on specialists. Ameriflex helps ensure claims procedures are compliant and smooth for both HR and employees.

5. Stay Audit-Ready

The Department of Labor regularly audits benefit plans, often triggered by participant complaints, red flags in Form 5500s, or fiduciary gaps. Auditors typically review:

  • Fiduciary oversight
  • Fee reasonableness
  • Disclosure timing
  • Prohibited transactions

Example: A DOL audit uncovers that a company failed to monitor service provider fees, raising questions about fiduciary oversight.

Avoid headaches: Conduct internal reviews, keep documentation tight, and work with ERISA experts to spot issues early. Ameriflex helps HR teams prepare for audits, perform reviews, and implement corrective actions.

You Don’t Have to Do This Alone

ERISA can feel overwhelming, but with the right systems and partners, it’s manageable. Treat compliance as an ongoing commitment, not a one-time project.

Ameriflex works alongside HR leaders to keep plans compliant, employees protected, and processes streamlined. From fiduciary guidance to plan documents, claims management, and audit support, we help you focus on your people, not the paperwork.
