A Year-End Checklist for Traditional and Safe Harbor 401(k) Plans for an Employer
The popularity of 401(k) plans today is because they offer certain tax advantages to employers and employees. For employers to qualify to have 401(k) plans, they must meet specified fiduciary responsibilities. Managing these tasks is complicated and can feel, at times, overwhelming. Receiving guidance from a financial professional can help you navigate the myriad of tasks you might face. We compiled a year-end checklist to help you get organized in preparation for that consultation with a financial professional.
☐ Have you completed all the required tasks?
☐ Has your plan document been updated within the past few years?
- Have you distributed the following required notices?
- Qualified Default Investment Alternative (QDIA) notice
☐ Safe harbor 401(k) notice (if applicable)
- Automatic (negative) enrollment notice
- Participant fee disclosure notice
- Forms or website instructions (for newly eligible employees)
- Beneficiary designations (for newly eligible employees)
☐ Have you completed the nondiscrimination tests? (This only applies to Traditional 401(k) plans)
The Employment Retirement Income Security Act (ERISA) requires several tests annually to ensure 401(k) plans do not discriminate in favor of employees earning higher incomes. The tests get broken up between non-highly compensated employees (NHCEs) and highly compensated employees (HCEs). To be considered a highly compensated employee, you need to:
- Own more than five percent of the interest in the business at any time during the year or the preceding year without regards to the amount of compensation earned or received. [i]
- Being in the top 20 percent of employees when ranked by compensation, or, for the preceding year, received compensation from the business of more than $155,000 (2024), up from $150,000 in 2023.
Once the NHCEs and HCEs are identified, you look into the plan’s benefits, rights, and features to ensure they are non-discriminatory. The actual deferral percentage (ADP) and actual contribution percentage (ACP) tests are used for this purpose.
- Actual Deferral Percentage (ADP)/Actual Contribution Percentage (ACP) test
- Excess deferral (IRC section 402(g)) test (Included in the ADP test in the year the amounts were deferred)
- Annual addition (IRC section 415(c)) test
- Rate group (IRC section 401 (a)(4)) test [ii]
- Top heavy (IRC section 416) test. Lastly, the top-heavy test evaluates the overall benefits that key employees have accumulated. Suppose the total value of the plan accounts of key employees is more than 60 percent (different from HCEs) of the total value of the plan assets. In that case, the plan is top-heavy, and certain minimum benefits may need to be provided to the non-key employees. If a 401(k) plan is top-heavy, the employer must contribute up to three percent of compensation for all non-key employees. To be a key employee requires the employee to be:
- An officer making over $220,000 (for 2024);
- Be a five percent owner of the business; or
- An employee owning more than one percent of the business and making over $150,000 for the plan year.
A non-key employee is everything else. [iii]
☐ Are you up-to-date on contributions, distributions, deposits, and refunds to correct failed ADP/ACP tests?
- If your employees have Safe Harbor 401(k) plans you are required to contribute to their accounts whereas a Traditional 401(k) plan does not require it, but contributions can be made. Both Safe Harbor and Traditional plans have an annual contribution limit that may not exceed the lesser of 100% of your compensation or $69,000 for 2024 ($66,000 for 2023). [iv] This includes elective deferrals, employee contributions, employer matching, discretionary contributions, and allocations of forfeitures but does not include catch-up contributions for those aged 50 and older. However, if you are 50 or over, you qualify for catch-up contributions, increasing the ceiling to $76,500 ($73,500 for 2023). [v]
- Matching or nonelective contributions made to appropriate employees under the plan terms
- Top-heavy minimum contributions made
- Hardship distributions made
- Safe harbor or Qualified Non-Elective Contribution (QNEC) contributions made
- Distribute contribution refunds to correct a failed ADP/ACP test with a 10 percent excise tax (non-safe harbor plans only)
- Distribute Required Minimum Distributions (RMDs) to participants that became RMD-eligible in the prior year
- Ensure employee salary deferrals and loan payments are deposited timely
- Cash-out account balances associate with terminated employee participants
- Process any defaulted loans
- Use any unallocated forfeitures
- Deposited employee elective deferrals
☐ Are all eligible employees identified and given the opportunity to make an elective deferral? [vi]
☐ Was form 5500 filed? [vii]
☐ If IRS form 5500 was not filed did you request an extension to file it using IRS form 5558?
☐ Have you taken the steps to seek guidance from a financial professional?
- There is a lot involved with year-end 401(k) planning if you are an employer. Still, with the help of an experienced financial professional, you can create a strategy to manage some of the potential challenges that come with completing the necessary fiduciary responsibilities.
