Could A Safe Harbor 401(k) Be A Simpler Retirement Plan Solution For Your Small Business?

Hiring an Accountant for Small Businesses: Pros and Cons

If you’re a small or mid-sized business that is now in a position to sponsor a qualified retirement plan, you may find yourself coming up against a series of complicated administrative requirements; a common obstacle. Are you ready to start dealing with the potential hassle and expense of IRS-mandated testing? Don’t you have enough to deal with already as a small business owner?

If you answered no and yes respectively, it might be worth taking some advice from professional tax preparation in Coral Gables, who could help you understand the benefits of a retirement plan known as a safe harbor 401(k). Designed to make administrative requirements simpler, and enable employees who are highly compensated to make contributions of the most allowable amounts, read on to discover whether you could benefit from a safe harbor 401(k) retirement plan:

Simple trade-off

Traditional 401(k) retirement plans are subjected under IRS regulations, to non-discrimination testing that takes place annually. This includes the following two tests:

  • The actual contribution percentage test, or ACP
  • The actual deferral percentage test, or ADP

In essence, these tests make sure that a company’s chosen retirement plan doesn’t place an unfair advantage on those employees that are more highly compensated than others within the company.

Should a plan fail either of these tests, extra contributions may have to be paid to other employees, or returned to highly compensated employees, in order to address the imbalance. This typically leads to disgruntled employees, administrative stress and costs the business could likely do without.

A safe harbor 401(k) on the other hand, involves the employer-sponsor agreeing to make contributions to employees accounts, mandatorily. The IRS, in exchange, agree to waive their requirement to carry out the above two tests every year.

Once this testing is no longer in the picture, failing them simply isn’t a concern, and employees who are highly compensated, can maximize their contributions.  

Some important caveats to take note of

The main caveat to be aware of, is the requirement for you to contribute compliantly to the accounts of every participant of the plan. In general, you can choose between the two outlined below:

  • A qualifying matching contribution, which may be 100% of the first 3% of compensation deferred, plus 50% of the next 2% deferred
  • A nonelective contribution totalling a minimum of 3% of the compensation for every participant who’s eligible

It’s also important to know that all necessary paperwork must be completed and notices delivered to employees by the 1st of October 2026 if you want to set up a safe harbor 401(k) this year, and contributions must start before the 1st of November 2026. Luckily, that gives you plenty of time if you’re thinking about setting it up this year.

You must also inform employees adequately of their rights, and outline in full, all details of your required contributions as their employer, following IRS rules as you do so.

The potential pitfalls

A commitment to making qualifying employer contributions is required with this retirement plan, and once you make that commitment, reducing or stopping them for any reason could trigger extra requirements from the IRS, or a disqualification from the plan.

Although these are exceptions, qualifying for them is complicated and working with an accountant in Coral Gables is strongly recommended.

Also of note, once funds are transferred into a participants account, they belong to them, regardless of whether they leave your employ.

If your business typically experiences fluctuations in cashflow throughout the course of each year, choosing this type of retirement plan might be too risky. But, if managing the mandatory contributions is within the realms of possibility, a safe harbor 401(k) might be suitable, and an assessment from an accounting service can help you make an informed decision.
