❓ Frequently Asked Questions
What is a Solo 401(k) and who is it for?
A Solo 401(k) is a retirement plan for self-employed individuals with no employees (other than a spouse). It lets you contribute as both employee and employer, often offering higher limits and flexible investment options.
How does a SEP IRA differ from a Solo 401(k)?
A SEP IRA is employer-funded only and easy to set up; all eligible employees must receive the same percentage of their compensation. A Solo 401(k) allows employee deferrals plus employer contributions, usually with higher total limits and better for owners with no or few employees.
How do contributions work in a Solo 401(k)?
You contribute as an employee (deferral) and as an employer (profit‑sharing). The combined annual limit depends on your compensation and plan rules, and catch‑up contributions are available if you’re 50 or older.
Which plan is best for my business?
If you have employees and want simplicity, a SEP may be easier. If you’re a sole proprietor or have no eligible employees, a Solo 401(k) often offers higher contribution potential and more investment flexibility (with some plans also allowing loans).
