Automatic enrollment in the Solo 401k
The Automatic Enrollment feature can be added to your Solo 401k plan, allowing you to receive a $1500 tax credit over 3 years.
What it is
The Automatic Enrollment feature allows employers to contribute a default portion (e.g. 3%) of an employee’s wages to the retirement plan, on the employee’s behalf.
With the Solo 401k, you are typically both the employer and the employee. You may also have a spouse as an additional employee. By adding the automatic enrollment feature, you are setting a default contribution to be made for each employee in the plan.
With this feature, the IRS allows you, as the employer, to claim a $1500 tax credit over 3 years- a $500 dollar-for-dollar tax reduction per year if you maintain the arrangement over 3 years.
Applies to the employee contribution
With Automatic Enrollment, the employer must make at least a 3% salary deferral contribution for each employee. This is typically done as a pre-tax employee contribution.
However, the employee can elect to do otherwise by completing an election form within a certain time frame. The employee can elect to:
- Make a portion or all of the contribution as Roth
- Make a greater contribution than the 3%
- Make a lesser contribution than the 3%
- Not make the contribution at all
To make this election, the employee must complete the Deferral Election form. This form is located in our Miscellaneous Forms section:
The completed Deferral Election form is submitted to the plan administrator. Typically, this is you- you are the employee, employer, and the plan administrator.
The employee must complete the Deferral Election Form and then typically, also keep the form as plan administrator. This form must be completed within 60 days of receiving the notice.
Note that the limits for the employee salary deferral contribution still apply to this arrangement:
- The employee salary deferral contribution limits still apply. For example, the limit for 2024 is $23,000.
- The employee salary deferral contribution, as the employer profit sharing contribution, is based on your compensation from the adopting business.
- The employee salary deferral contribution limits are per person, not per plan. If you have already reached the limit through another employer-sponsored plan for the year, you will not be able to make this contribution to this plan.
- All employee elective deferral contributions, including those under this arrangement, cannot be withdrawn from the plan unless you are 59.5 or older.
Requirements for the arrangement
The Automatic Enrollment feature must be for the full plan year. It has two requirements:
- Uniformity requirement: The arrangement must uniformly apply to all employees after giving them the required notice.
- Notice requirement: A notice of the Automatic Enrollment must be given to all employees within a reasonable period of time, e.g. 30 days before the arrangement is adopted. Notices must also be given to all employees in subsequent years.
Your first notice is included in your set of plan documents (“Automatic Enrollment Notice”). Please review the notice carefully.
Claiming the tax credit
The $1500 tax credit is given over 3 years at $500 per year. You must maintain the Automatic Enrollment feature for all 3 years to claim the tax credit. The tax credit is a dollar-for-dollar reduction (vs. a deductible expense).
To claim the credit, you must file Form 8881 for the first year Automatic Enrollment was included in your plan:
