For self-employed individuals and small business owners, planning for retirement can be challenging without access to traditional employer-sponsored plans. However, the Solo 401(k) provides a powerful solution. This article dives into the benefits, requirements, and strategies for leveraging a Solo 401(k) to secure your financial future.
What is a Solo 401(k)?
A Solo 401(k), also known as a one-participant 401(k), is a retirement savings plan designed specifically for self-employed individuals or small business owners with no employees, except for a spouse. It offers the same benefits as a traditional 401(k) but with added flexibility tailored for entrepreneurs.
Eligibility Requirements
To qualify for a Solo 401(k):
- You must earn income through self-employment.
- Your business can’t have employees, apart from a spouse.
- The business structure can vary—sole proprietorship, LLC, corporation, or partnership.

Tax Advantages
