Staying Ahead in 2025 – Compliance Deadlines You Don’t Want to Miss! 

Start 2025 off on the right foot! Here’s a rundown of some compliance and testing dates and deadlines to keep in mind for 2025: 

ADP (Actual Deferral Percentage) and ACP (Actual Contribution Percentage) tests are IRS nondiscrimination tests that ensure 401(k) plans don’t favor highly compensated employees (HCEs) over non-highly compensated employees (NHCEs). If a plan is Safe Harbor, it automatically passes these tests. 

  • January 31, 2025: Deadline for plan sponsors to submit the Annual Plan Questionnaire & 2024 Employee Census Data in good order to ensure testing and employer contribution deadlines are met. 
  • March 6, 2025: Deadline for plan sponsors to sign off on ADP/ACP test results to ensure timely processing of any applicable corrective distributions. 
  • March 17, 2025: Deadline for processing most ADP/ACP corrective distributions to avoid a 10% excise tax.

*Note that the plan sponsor is responsible for paying this excise tax if applicable. 

The Form 5500 is a required filing with the DOL and contains information about a 401(k) plan’s financial condition, plan qualifications, and operation. The form aims to provide the IRS and DOL with information about the plan’s operation and compliance with government regulations.

  • April 15, 2025: Deadline for C-Corps and Sole Props to make 2024 employer contributions for tax deductibility purposes when filing without an extension.
  • July 31, 2025: Standard deadline for filing Form 5500/5500-SF without an extension. 
  • October 15, 2025: Final deadline for submitting Form 5500/5500-SF if Form 5558 was filed for an extension. 
  • September 15, 2025: Deadline for plan sponsor to communicate any requested Plan amendments for an effective date of January 1, 2026.
  • December 1, 2025: Deadline for plan sponsor to distribute required Plan notices for the 2026 plan year.
  • December 29, 2025: Deadline for processing corrective distributions for failed ADP/ACP tests for the plan year ending December 31, 2024, to avoid plan disqualification.
