If you have yet to develop a retirement plan for your business, or if you're not sure the plan you've chosen is the right one, here are some things to consider.

How much can my business afford to contribute?

The cost of contributions may be managed by the plan type.

A simplified employee pension plan (SEP) is funded by employer contributions only. SEP contributions are made to separate IRAs for eligible employees.1

Savings Incentive Match Plan for Employees of Small Employers (SIMPLE) IRAs blend employee and employer contributions. For example, some employers match employee contributions up to 100% of the first 3% of compensation. Others may contribute 2% of each eligible employee’s compensation. It’s up to the employer to decide the formula based on what works best for the business.2

A 401(k) is primarily funded by the employee; the employer can choose to make additional contributions, including matching contributions.3

What plan accommodates high employee turnover?

The cost of covering short-tenured employees may be managed by eligibility requirements and vesting.

With the SEP-IRA, only employees who are at least 21 years old, earn at least $750 in compensation, and have been employed in three of the last five years must be covered.4

The SIMPLE IRA must cover employees who have earned at least $5,000 in any prior two years and are reasonably expected to earn $5,000 in the current year.5

The 401(k) and defined benefit plan must cover all employees who are at least 21 years of age. These retirement plans are open for employees who have either worked 1,000 hours in the space of one full year or to those who have worked at least 500 hours per year for three consecutive years.6,7

Vesting is immediate on all contributions to the SEP-IRA, SIMPLE IRA and 401(k) employee deferrals, while a vesting schedule may apply to 401(k) employer contributions and defined benefits.

Do I want to maximize contributions for myself (and my spouse)?

The SEP-IRA and 401(k) offer higher contribution maximums than the SIMPLE IRA. For those business owners who are starting late, a defined benefit plan may offer even higher levels of allowable contributions.

My priority is to keep administration easy and inexpensive.

The SEP-IRA and SIMPLE IRA are straightforward to establish and maintain. The 401(k) can be more onerous, but complicated testing may be eliminated by using a Safe Harbor 401(k). Generally, the defined benefit plan is the most complicated and expensive to establish and maintain of all plan choices.
