A well-designed 401(k) plan can help to recruit and retain employees, and – for most workers who have access to a company 401(k) plan – it serves as the primary (or only) investment vehicle to accumulate savings for retirement.  For many employers, the 401(k) plan’s effectiveness in helping owners and key personnel to save meaningful amounts for retirement is limited by annual compliance testing required by the IRS.  In this article, we describe those compliance testing requirements and explain how a safe harbor contribution provision offers several advantages in giving the plan an exemption to those testing requirements.

The Actual Deferral Percentage (ADP) Test

What is the ADP test and how does it work?

Required to be performed annually, the actual deferral percentage (ADP) test exists to help ensure that non-highly compensated employees (NHCEs) are – on average – able to make 401(k) contributions at near the same rate as the employer’s highly compensated employees (HCEs).  HCE and NHCE are defined by the IRS.

An HCE is anyone who:

1) owns more than 5% of the business,

2) is related to a 5%+ owner as a spouse, child, parent, or grandparent, and/or

3) had gross wages from the employer of $130,000+ in the prior year. 

Everyone else is an NHCE.

Each year the plan is required to calculate the average 401(k) contribution percentage for the HCE group, and to do the same for the NHCE group.  For example, if there are three HCEs who contribute 3%, 7%, and 8%, the HCE group’s “average deferral percentage” would be (3%+7%+8%) / 3 HCEs = 6%.  Once the same average deferral percentage is calculated for the NHCE group, the HCE and NHCE groups’ averages are compared.  If the HCE group’s average doesn’t exceed the NHCE group’s average by more than 2%, testing passes and no corrective action is required.  If the HCE group’s average exceeds the NHCE group’s average by more than 2%, testing fails and the plan is required to make “corrective taxable refunds” to the HCE(s) who contributed the most (and who caused the testing failure) to bring the HCE group’s average down to the 2% threshold required to pass testing.  The purpose of corrective taxable refunds is to remove the excess HCE 401(k) contributions from the plan and treat them as if they had not been contributed to the plan in the first place.  (If the testing sounds complex, don’t worry: each year it is performed by the plan’s third party administrator (TPA), who communicates the results – and any required corrective action – to the employer.)

What happens if a 401(k) plan fails an ADP Test?

ADP test failures are common, and can make for unhappy HCEs when they’re told they’ll be receiving a corrective taxable refund.  For plans that are subject to the ADP test each year, it is generally recommended that the employer – with the help of the plan’s third-party administrator (TPA) – be proactive in limiting or eliminating the possibility of an ADP testing failure.  This is usually accomplished by first estimating the NHCE group’s average deferral percentage and then communicating to all of the HCEs that they are only able to make 401(k) contributions up to the NHCE group’s average plus 2%.  Unfortunately, this can still make for unhappy HCEs who would like to make 401(k) contributions up to the annual IRS limit of $19,500 (plus an additional $6,500 “catch-up” contribution for those age 50+).  Note: this limit applies in 2020 and is indexed for cost-of-living adjustments.

A Safe Harbor Contribution Provision

Fortunately, the IRS offers employers a way to give the plan a complete exemption to the ADP test, thereby enabling HCEs to make 401(k) contributions up to the annual IRS limit without the possibility of an ADP testing failure resulting in corrective taxable refunds.  To gain an exemption to the ADP test, the employer can make one of two types of safe harbor contributions: a 3% safe harbor “nonelective” contribution or a 4% safe harbor “matching” contribution.

What are the employer’s different options for making a safe harbor contribution?

Option 1 – Safe Harbor 3% Nonelective

In a 401(k) plan, “nonelective” means “not conditioned on employees making 401(k) contributions”, so under this first option the safe harbor nonelective contribution is made as 3% of gross pay to all eligible plan participants whether or not they make 401(k) contributions.

Option 2 – Safe Harbor 4% Matching

The 4% safe harbor matching contribution is a “company match”, so it is conditioned on employees making 401(k) contributions.  The “basic” (i.e., minimum required) IRS safe harbor matching contribution formula is a 100% match on the first 3% of 401(k) contributions and a 50% match on the next 2% of 401(k) contributions, for a maximum matching contribution of 4%.  If this sounds too complicated, you’re not alone.  The IRS permits the plan to use an “enhanced” safe harbor matching contribution formula as long as that formula is at least as favorable as the IRS “basic” formula at all 401(k) contribution levels.  Many employers prefer a safe harbor matching contribution formula of 100% on the first 4% of 401(k) contributions because it is generally easier for employees to understand and it is easier to calculate and fund to the plan.

The type of safe harbor contribution that is made to the plan is determined by the employer; there is no requirement that one option be used versus the other.  And regardless of the type of safe harbor contribution that is made, the employer is given the option to fund the contribution to employee accounts each payroll period throughout the year, or in a single lump sum deposit after the end of the year (if the latter is selected, the contribution must be funded by the employer’s tax filing deadline – including extensions – to be tax deductible to the employer for the year of the contribution).

Which employees must receive the safe harbor contribution?

HCEs are usually included in the safe harbor contribution allocation, but they don’t have to be.  The IRS permits the employer to exclude HCEs from the safe harbor allocation and still gain an exemption to the ADP test.  Excluding HCEs from the safe harbor contribution is most commonly done by employers who want HCEs to be able to contribute 401(k) up to the annual IRS maximum, but who don’t have it in the company budget to fund a safe harbor contribution to the HCE group.

What other requirements apply to the safe harbor contribution?

The safe harbor contribution is a “fixed” contribution that is written into the plan document and represents a commitment to employees.  By adding a safe harbor contribution provision to a 401(k) plan, the employer obligates itself to making the safe harbor contribution for the full 12-month plan year.  A safe harbor contribution provision can be removed from a plan with a plan amendment, but – with few exceptions – this can only be done as of the beginning of the next plan year.

A couple other requirements apply to safe harbor contributions that do not apply to more traditional “discretionary” matching and profit sharing contributions.  First, safe harbor contributions are required to be immediately 100% vested and cannot be subject to a vesting schedule.  Second, safe harbor contributions cannot be subject to “allocation conditions” whereby an employee is only eligible for an employer contribution if they are employed as of the last day of the plan year and/or worked at least 1,000 hours with the employer during the year.  The safe harbor contribution is made to all employees who were eligible for the plan at any time during the year.

In a safe harbor 401(k) plan, at least 30 (but no more than 90) days prior to the beginning of each plan year the employer is required to distribute a “safe harbor notice” to employees notifying employees of the safe harbor contribution that will be made for the upcoming year.  The notice is required in order to give employees time to consider what 401(k) contributions they would like to make for the coming plan year in light of the fact that the safe harbor contribution will be made.

Leveraging Safe Harbor to Increase Employer Contributions to Owners and HCEs

Many employers wish for the business’ owners (and perhaps other HCEs) to receive more than the maximum annual 401(k) contribution plus the safe harbor contribution.  While doing so is possible with a discretionary profit sharing or matching provision, it is often determined to be cost-prohibitive because those contributions must be made uniformly to all eligible plan participants, including NHCEs.

There is a special type of employer contribution, however, that can enable the employer to make significant additional contributions to the accounts of owners/HCEs with only a nominal increase to the employer contributions made to NHCEs (or in some cases no increase at all).  This is accomplished with an “age-based” (sometimes referred to as “cross-tested” or “new comparability”) employer profit sharing contribution provision.

Here’s how it works: “Profit sharing” is another term that is often used for a discretionary “nonelective” contribution.  In this context, “nonelective” means the same thing as it does for the safe harbor 3% contribution type described earlier in this article: not conditioned on employees making 401(k) contributions.  Because an age-based profit sharing contribution is a type of nonelective contribution, it is included in the same set of nondiscrimination/actuarial testing as the safe harbor 3% nonelective contribution.  This enables the employer to “layer” profit sharing contributions on top of a safe harbor 3% nonelective contribution in a way that significantly – and legally – skews those additional profit sharing contributions in favor or owners and HCEs.

Because the nondiscrimination/actuarial testing is age-based, this “layering” concept only works in situations where the owners/HCEs who are being targeted for additional profit sharing contributions are – on average – older than the NHCEs.  The targeted owners/HCEs don’t need to be older than all of the NHCEs, but if the average age difference is significant (i.e., a decade or more), age-based profit sharing tends to work very well.

It should be noted that – because a safe harbor 3% nonelective contribution creates a 3% contribution “base” in the testing of nonelective contributions – safe harbor 3% nonelective works far better than the safe harbor 4% matching option with an age-based profit sharing contribution.

Many employers use this plan design (safe harbor 3% nonelective plus discretionary age-based profit sharing) as the lowest-cost method to maximize annual contributions to the 401(k) plan for owners at the IRS total annual contribution limit of $57,000 ($63,500 for those age 50+), and at a relatively low employer contribution expense for NHCEs.

Summary

In addition to demonstrating the employer’s commitment to helping employees save for a comfortable retirement, a safe harbor provision has several advantages.  Most importantly, it gives the plan an exemption to the ADP test and enables the employer’s owners and highly-compensated employees (HCEs) to maximize 401(k) contributions at the annual IRS limit without the possibility of corrective taxable refunds.  And for businesses for which the owners tend to be – on average – older than NHCEs, a safe harbor provision creates a contribution “base” on which additional profit sharing contributions can be layered to disproportionately favor the targeted owners and HCEs.

There are certainly many different considerations in determining whether a safe harbor contribution provision is a good fit for an employer and its 401(k) plan.  TRPC works with hundreds of employers to implement and administer safe harbor 401(k) plans, and we welcome an opportunity to speak with you whether you are considering adding a safe harbor provision to an existing 401(k) plan or starting a brand new safe harbor 401(k) plan.
