The Dreaded 401(k) Refund: Corrective Distributions

The Dreaded 401(k) Refund: Corrective Distributions

March 25, 2024

Perhaps due to early experiences with annual tax returns, many hear the word refund and begin running down their wish list of ways to spend this extra money. However, when it comes to 401(k) refunds, or corrective distributions, the excitement should be dialed back.  

Corrective distributions are a headache for plan sponsors and employees alike. Essentially, these refunds mean that your plan has failed testing and tax deferred money that key employees set aside for retirement has to be returned to them. This is an issue for both you and your employees - in this article we are going to discuss what to do if you are caught in this situation. 

Highly Compensated Employees  

Your workforce is made up of two distinct employee demographics: highly compensated employees (HCEs) and non-highly compensated employees (NHCEs), also known as “rank-and-file”. An HCE is one who owns 5% or more of the company, a direct family member of an owner or earns more than $120,000 per year. NHCEs make up the remainder of your workforce.  

These two groups share a common goal of reaching retirement, and although HCEs may be able and willing to contribute more, your plan should be designed with both parties in mind. The IRS requires that both highly compensated plan participants and rank-and-file plan participants contribute to their 401(k) plans at similar rates.  

Understanding Testing Requirements 

If the idea of calculating and comparing percentages sends you down a path of traumatic flashbacks of math class, don’t worry. Our goal is to simplify and educate, not overwhelm. If you have more questions, we are happy to have that conversation.     

ADP Testing 

ADP stands for actual deferral percentage, and the testing for it compares the average of salary deferral percentages for HCEs with the average of salary deferral percentages for NHCEs. The ADP test applies to pre-tax and Roth elective deferrals, and its purpose is to ensure that all employees are benefitting from the plan. To pass ADP testing, the average contributions of HCEs must not exceed NHCE contribution by a factor of 1.25 or 2 percentage points as illustrated in the chart below: 


ACP Testing 

ACP stands for actual contribution percentage test It is similar to the ADP test, but it only tests employer matching contributions. So, ACP only applies to companies that offer a company match. It compares the average of the percentage of matching contributions and after-tax employee contributions for HCEs versus NHCEs.  

Top-Heavy Test 

The Top-Heavy Test looks at how much HCEs contribute to the plan compared to everyone else. If key employee balances exceed 60% of the entire plan balance at the end of the plan year, the employer is required to make a 3% contribution to the non-key employees in order to achieve a non-discriminatory status. 

What if Testing Fails? 

401(k) test failures are no fun for anyone, and it requires swift action for employers and plan sponsors alike. To correct plan failures, additional contributions or corrective distributions may be required. This means the possibility of pre-tax savings returned to employees, requiring owners and key employees to refile their taxes… talk about a nightmare!     

Can Testing Be Avoided? 

A Safe Harbor Plan eliminates the need for non-discriminatory testing. These plans automatically pass ADP/ACP testing when certain contribution and participant notice requirements are met. To fulfill the requirements, employers must make one of the following contributions: 

Basic matching – The company matches 100% of all employee 401(k) contributions, up to 3% of their compensation, plus a 50% match of the next 2% of their compensation. 

Enhanced matching – The company matches at least 100% of all employee 401(k) contributions, up to 4% of their compensation (not to exceed 6% of compensation). 


A non-elective contribution of not less than 3% of compensation is made by the employer to all eligible employees, regardless of whether they defer under the 401(k) arrangement. The 3% contribution must be set by the plan document and may provide that this contribution be made to only NHCEs. 


QACA safe harbor match – The QACA safe harbor matching contribution formula is a 100% match 

on the first 1% of compensation deferred and a 50% match on deferrals between 1% and 6%. 


  • A two-year cliff vesting schedule may be applied to QACA safe harbor contributions; and 
  • Unless the participant elects otherwise, the deferral rate starts at no less than 3% and increases at least 1% annually to no less than 6% (with a maximum of 10%). 

While a Safe Harbor plan allows owners and highly compensated employees to maximize deferrals, they do require specified employer contributions, and all contributions are immediately vested. Another factor to consider is distribution of employee communication. Plan sponsors are responsible for notifying participants of their plan rights and obligations within 90 days of their plan eligibility date and 30-90 days before the start of each new plan year thereafter.
