What’s the difference between a standard 401(k) and a Starter 401(k) with Guideline?
What’s the difference between a standard 401(k) and a Starter 401(k) with Guideline?

Here’s a comparison between the requirements and plan features of standard 401(k) and Starter 401(k) plans.

Updated over a week ago

At Guideline, we want to make retirement benefits accessible for all businesses – big and small. That's why we offer both standard 401(k) plans and Starter 401(k) plans, so employers can select the option that best fits their needs.

Standard and Starter 401(k) plans are similar in nature – they both offer the opportunity for employees to contribute to a retirement plan through their employer and are funded with automatic deferrals pulled from employees' paychecks. However, there are also significant differences in the requirements and features of each.

Can I move from one plan type to the other?

Moving to a Starter 401(k) plan

If an employer currently offers or will offer a standard 401(k), the plan will not be eligible to convert to a Starter 401(k) plan at a later date without terminating and waiting for a full 12 months to pass. Starter 401(k) plans are designed for businesses that have not offered any employer-sponsored retirement plan in at least 12 months.

Moving to a standard 401(k) plan

It is possible for a plan to convert from a Starter 401(k) to a standard 401(k) plan. However, the transition cannot take place within the same year. While an employer can request a plan amendment to move from a Starter 401(k) to a standard plan in advance, the change will not be effective until the beginning of the next calendar year.
