How To

  1. Understand the Testing Requirements: Familiarize yourself with the two primary tests: the Actual Deferral Percentage (ADP) test for employee contributions and the Actual Contribution Percentage (ACP) test for employer matches.
  2. Monitor Contributions Quarterly: Regularly track employee contributions to identify any discrepancies between HCEs and NHCEs. This will help you make timely adjustments.
  3. Evaluate Plan Design: Consider adopting a safe harbor plan, which can exempt you from nondiscrimination testing while also increasing NHCE participation.
  4. Use Compliance Software: Invest in software that can help automate the testing process and provide projections based on current contribution patterns.
  5. Communicate with Employees: Ensure that all employees understand the contribution limits and the importance of equitable participation in the 401(k) plan.
  6. Prepare for Corrections: If you anticipate potential failures, familiarize yourself with corrective measures such as refunds or reallocations, as outlined in the IRS guidelines.
  7. Consult Professionals: If your plan is complex or if you encounter issues during testing, consider consulting a retirement plan professional for guidance.
  8. Document Everything: Keep detailed records of all contributions, testing results, and communications to ensure compliance and facilitate audits.
  9. Review Limits Annually: Stay updated on annual contribution limits and adjust your plan accordingly. For 2025, the maximum employee deferral limit is $23,500, with a catch-up contribution of $7,500 for those aged 50 and above according to the IRS.
  10. Prepare for the Deadline: Ensure that all tests are completed by the end of the plan year (typically December 31) and that any necessary corrections are made by the tax filing deadline (April 15, 2026).
