Updated over a year ago

If you set up your Solo 401k plan near the end of the year, there are two things you must to so your plan is qualified:

  1. Complete your 401k plan docusign

  2. Formally elect your Solo 401k Contributions

Complete your 401k plan docusign

The IRS closes the last week of the calendar year. During this time, we can't get a new EIN for yoru 401k trust but we can still prepare your 401k plan documents.

If you submitted your Solo 401k plan application during the IRS planned closure (last week of the year), you'll see 11-111111 listed as the trust tax ID number temporarily. We'll have a tax ID number for your new 401k trust just after the new year.

You have until tax day to deposit contributions into your Solo 401 plan.

Having your plan documents from us is what makes you qualified for the current tax year, even if we haven't yet obtained your 401k trust tax ID number. We will obtain your new Solo 401k tax ID number when the IRS reopens.

If contributions are your main objective for having the plan open in 2023, you'll need to complete a contribution form (that we will provide)so you can make your formal election to contribute.
​
After you complete the contribution form, store it in a safe place with your signed 401k plan signature pages. You may send a copy to your CPA and/or tax advisor. You do not need to send anything to Nabers Group.
