Determining $250K Value QUESTION:

  • The total plan assets for all participants under the solo 401k plan must be added to determine if the cumulative balance is over $250,00.
  • IMPORTANT: If you participate in multiple solo 401k plans, all the plans assets must be aggregated to determine if the $250,000 threshold has been met. If your self-employed business also sponsors a defined benefit plan (DBP) also know as a Cash Balance Plan, the assets of the solo 401k plan and the DBP must be combined to determine if the greater than $250,00 threshold is met by both plans combined; if it does, a separate Form 5500-ez is required to be filed for each plan.
  • If you borrowed from the solo 401k plan (i.e., took a solo 401k participant loan), the balance of the loan as of December 31, 2025 is treated as an asset not a liability so it must be included in the calculation to determine if the $250K threshold filing requirement has been met.

Value of Real Estate and Alternative Investments QUESTION:

For alternative investments, you need to make a reasonable determination of the value of the solo 401(k)'s ownership interest in the investment as of December 31, 2025:

  • For an interest in a partnership, this will not be the amount listed on the K-1 but rather the value of such partnership interest.

Foreign Solo 401k Investments QUESTION:

Foreign investments do not trigger the Form 5500-EZ filing requirement unless when the value of the foreign investment(s) is included in the total value of the solo 401k plan causes the plan to exceed $250,000 in total value.

Reason being, a foreign plan is solo 401k plan maintained outside the U.S. primarily for nonresident aliens.
