Mastering Form 5500 Compliance: Common Errors and How to Avoid Them

As a Third-Party Administrator (TPA) dedicated to supporting financial advisors and their clients, we understand the critical importance of accurate Form 5500 filings. The annual Form 5500 is more than just a regulatory requirement—it’s a cornerstone of retirement plan compliance. Errors can expose plan sponsors to audits, penalties, and reputational damage. Fortunately, with the right guidance and processes, most mistakes are entirely avoidable.

Here are the top Form 5500 errors we see—and how you, as a financial advisor, can help your clients steer clear of them. 

1. Incorrect Plan Information

Common Error: 
Entering the wrong plan name, plan number, or Employer Identification Number (EIN) is surprisingly common and can delay processing or trigger red flags. 

How to Avoid: 

  • Double-check all identifying information before submission. 
  • Maintain a master file with up-to-date plan details. 
  • Use the same plan number consistently from year to year. 

2. Missing or Invalid Electronic Signatures

Common Error: 
Form 5500 must be electronically signed via the DOL’s EFAST2 system. Missing or invalid signatures will result in immediate rejection. 

How to Avoid: 

  • Ensure the plan administrator has an active EFAST2 account. 
  • Confirm the signer’s credentials and access well before the filing deadline. 
  • Schedule a “signature day” to ensure timely completion. 

3. Late Filings

Common Error: 
Missing the July 31st deadline (for calendar-year plans) is a frequent and costly mistake. 

How to Avoid: 

  • Set calendar reminders for key deadlines. 
  • Start gathering data early—at least 90 days before the deadline. 
  • If more time is needed, file Form 5558 for an automatic 2.5-month extension. 

Common Error: 
Forgetting to attach required schedules (like Schedule A for insurance contracts or Schedule C for service providers) or providing incomplete information. 

How to Avoid: 

  • Review the plan’s structure annually to determine which schedules are required. 
  • Work with all service providers early to collect necessary data. 
  • Use a checklist to verify all schedules are attached and fully completed. 

5. Incorrect Participant Counts

Common Error: 
Misreporting the number of eligible or active participants can change the plan’s filing status (small vs. large plan) and audit requirements. 

How to Avoid: 

  • Regularly update participant records throughout the year. 
  • Include all eligible employees, even those not actively contributing. 
  • Reconcile year-end census with payroll data. 

Proactive Steps for Financial Advisors

  1. Educate Your Clients: 
    Host annual compliance reviews and remind clients of key filing requirements. 
  2. Collaborate with TPAs: 
    Maintain open communication with your TPA to ensure all parties are aligned and deadlines are met. 
  3. Leverage Technology: 
    Use secure portals and automated reminders to streamline document collection and signature processes. 
  4. Stay Informed: 
    Regulatory requirements change—subscribe to updates from the DOL, IRS, and your TPA.
