What is Solo 401(k)?

In short

A solo 401(k) is a 401(k) plan for a self-employed person with no employees other than a spouse. The owner contributes as an employee (elective deferrals) and as the employer (a profit-sharing contribution), up to a combined annual limit.

Key takeaways

  • Employer contributions for a sole proprietor are limited to 20% of net self-employment earnings (25% of wages for an incorporated owner).
  • Elective deferrals can be made as Roth contributions.
  • Once plan assets exceed $250,000, an annual return (Form 5500-EZ) is required.
