There's the traditional 401(k), of course. But there are also SIMPLE 401(k)s for small employers, 401(k)s with qualified automatic contribution arrangements (QACAs), and safe harbor 401(k)s.

The one thing all these special 401(k) plans have in common is that they're generally simpler to maintain because they're exempt from some or all of the complicated testing requirements that normally apply to traditional 401(k) plans. In order to qualify as a safe harbor plan, a 401(k) plan must meet special notice, contribution, vesting, and distribution requirements.
 

Special Contribution Requirements

In a traditional 401(k) plan you can, but you're not required to, make employer contributions. In contrast, you must make a fully vested contribution to a safe harbor plan. You have several options. First, you can make a contribution of 3% (or more) of pay on behalf of each employee eligible to participate in the plan. This "nonelective contribution" must be made even for participants who aren't actively contributing.

Alternatively, you can match employee contributions to the plan. If you use this approach, you must match each employee's contributions dollar for dollar up to 3% of that employee's pay, and match contributions from 3% to 5% at a 50% rate (the "basic match"). You also have the option of making an "enhanced" matching contribution that's at least as generous as the basic match, and that meets other requirements.

Your safe harbor contributions are generally subject to the same withdrawal rules that apply to employee 401(k) deferrals (that is, payouts are only allowed upon termination of employment, disability, death, hardship, or after age 59½).
 

Avoiding Testing Requirements

By using a safe harbor plan, you'll automatically satisfy the "actual deferral percentage" (ADP) test that compares the average deferrals of your higher paid and lower paid employees. This test often limits the amount that your higher paid employees can defer into the plan. If you make the basic safe harbor matching contribution, you'll utomatically satisfy the "actual contribution percentage" (ACP) test that applies to matching contributions. If you make additional matching contributions (including the enhanced match), you'll avoid ACP testing if you don't match employee contributions over 6% of pay, and any discretionary matching contributions don't exceed 4% of pay. Finally, you'll avoid top-heavy testing if you make only the safe harbor contribution to the plan.
 

Special Notice Provisions

You don't have to use the safe harbor rules every year. But for any year you do want safe harbor treatment, you must provide a notice to employees at least 30 days before the plan year starts. The notice must tell employees you'll be using the safe harbor rules for the following year, describe the safe harbor contribution you'll make, and explain the employees' rights and obligations under the plan. (Your formal 401(k) plan document must also include appropriate safe harbor language.)

You can also have a "flexible" safe harbor plan that lets you decide at year-end (instead of before the year starts) whether or not you'll use the safe harbor rules for that year. But this option is available only if you'll be making the 3% safe harbor contribution. You might find this plan design useful if you want to see how your discrimination testing is  progressing before you commit to a safe harbor contribution for the year. You'll still need to provide the notice to employees before the plan year starts, but the notice will tell employees that you may use the safe harbor rules for the following year. If you do decide to use the safe harbor rules, you'll have to inform your employees by sending a second notice no later than 30 days before the end of the plan year.
 

QACAs

A QACA may be an attractive alternative to a regular safe harbor plan if you like the idea of automatic enrollments.

A QACA is a 401(k) plan with an automatic ("negative") enrollment feature that avoids ADP, ACP, and top-heavy testing that meets certain requirements. While most of the rules applicable to safe harbor plans also apply to QACAs, there are some notable exceptions. Under a QACA, an employee who fails to make an affirmative deferral election is automatically enrolled in the plan. An employee's automatic contribution must be at least 3% for the first two calendar years of participation and then increase 1% each year until it reaches 6%. You can require an automatic contribution of as much as 10%. Employees can change their contribution rate, or stop contributing, at any time (and get a refund of their automatic contributions if they elect out within 90 days).

As with safe harbor plans, you're required to make an employer contribution; either 3% of pay to each eligible employee, or a matching contribution, but the match is a little different—dollar for dollar up to 1% of pay, and 50% on additional contributions up to 6% of pay. You can also require two years of service before your contributions vest (compared to immediate vesting in a safe harbor plan). And if you select certain default investments to hold employees' automatic contributions, you'll generally be relieved of fiduciary responsibility for any losses your employees incur while in those investments.
