Understanding Actual Deferred Percentage (ADP)

The Actual Deferred Percentage (ADP) is a measure used in 401(k) plans to ensure that highly compensated employees (HCEs) do not disproportionately benefit from the plan compared to non-highly compensated employees (NHCEs). The ADP test is part of the non-discrimination testing required by the IRS.

Components of the ADP Test

The ADP test involves several key components:

  • Calculating Deferrals: Determine the average percentage of compensation deferred by both HCEs and NHCEs.
  • Comparison: Compare the ADP for HCEs to the ADP for NHCEs to ensure compliance with IRS regulations.
  • Adjustments: If the ADP for HCEs exceeds the allowable limit, adjustments must be made to bring the plan into compliance.

Benefits of the ADP Test

The ADP test offers several benefits for 401(k) plan compliance:

  • Equity: Ensures that 401(k) plans benefit all employees, not just highly compensated ones.
  • Compliance: Helps plan sponsors comply with IRS regulations and avoid penalties.
  • Fairness: Promotes fairness and inclusivity in retirement savings plans.

Conducting the ADP Test

To conduct the ADP test effectively, plan sponsors should:

  • Gather Data: Collect data on employee deferrals, compensation, and classifications (HCE vs. NHCE).
  • Calculate ADP: Calculate the average deferral percentages for both HCEs and NHCEs.
  • Compare Results: Compare the ADP for HCEs to the ADP for NHCEs to determine compliance.
  • Make Adjustments: If necessary, make adjustments to deferrals or provide refunds to bring the plan into compliance.

Ensuring Compliance with the ADP Test

Regularly conducting the ADP test and making necessary adjustments ensures that 401(k) plans remain compliant with IRS regulations. This helps promote fairness and inclusivity in retirement savings, benefiting all employees.
