If you’re a freelancer, consultant, ecommerce seller, or small business owner with no full-time employees, a solo 401k can be one of the most powerful retirement tools available. Also known as an individual 401k, it allows you to contribute both as the employee and the employer, potentially maximizing your annual retirement savings while reducing taxes. Choosing the right solo 401k provider matters, especially when it comes to fees, investment options, and ease of administration. Below, we break down the top 10 solo 401k providers for business owners in 2026, helping you find the best fit for your financial goals.
1. Fidelity Investments Solo 401k
Fidelity Investments Solo 401k is a popular choice among business owners who want low costs and broad investment options. With no setup or annual maintenance fees, it’s especially attractive for cost-conscious entrepreneurs. You can invest in stocks, ETFs, mutual funds, and bonds, all within Fidelity’s robust trading platform. Their customer service is well regarded, and the account setup process is straightforward. However, the plan does not allow for Roth contributions in all cases and may have limited customization compared to specialized providers. Overall, it’s a strong option for business owners seeking simplicity, brand trust, and competitive investment choices.
2. Charles Schwab Individual 401k
Charles Schwab’s Individual 401k stands out for its user-friendly interface and commission-free stock and ETF trading. There are no account opening or maintenance fees, which makes it appealing for self-employed professionals and small business owners. Schwab offers a wide range of investment products, including its own low-cost index funds. The platform is intuitive and ideal for those who want hands-on control of their portfolio. However, alternative investment options are limited. For entrepreneurs who prefer traditional investments and a well-established brokerage experience, Schwab’s solo 401k is a reliable and efficient solution.
3. Vanguard Individual 401k
Vanguard is well known for its low-cost index funds, and its Individual 401k reflects that philosophy. Business owners who prioritize long-term, low-fee investing often gravitate toward Vanguard’s platform. There are no setup fees, and administrative costs are minimal. Investment options primarily include Vanguard mutual funds, making it ideal for passive investors focused on index strategies. However, it may not offer the flexibility of a fully self-directed solo 401k. If you believe in simple, diversified investing with a long-term mindset, Vanguard’s Individual 401k can be a powerful retirement vehicle for your business income.
4. E*TRADE Solo 401k
E*TRADE’s Solo 401k is designed for active investors who want flexibility and trading tools. With no setup or annual fees, it competes well with other major brokerage providers. Business owners can access stocks, ETFs, mutual funds, and options trading, making it attractive for those who manage their own investments. The platform also supports Roth contributions, which adds tax planning flexibility. E*TRADE’s strong online tools and educational resources are beneficial for entrepreneurs who want greater control over their retirement strategy. It’s a solid option for self-employed professionals comfortable navigating online brokerage platforms.
5. TD Ameritrade Solo 401k
TD Ameritrade’s Solo 401k, now integrated into Charles Schwab’s ecosystem, has long been known for powerful trading tools and flexibility. Business owners benefit from access to the thinkorswim platform, which is particularly useful for active traders. There are no annual maintenance fees, and investment choices are broad. While it may not support certain alternative investments directly, it works well for those focused on traditional securities. Entrepreneurs who actively manage portfolios or trade frequently may find TD Ameritrade’s former structure, now under Schwab, particularly appealing for its advanced research and trading capabilities.
6. MySolo401k Financial
MySolo401k Financial specializes in self-directed solo 401k plans, making it a favorite among business owners interested in alternative investments. With this provider, you can invest in real estate, private equity, cryptocurrency, and more. The plan supports both traditional and Roth contributions, along with loan provisions. While there is a setup and annual maintenance fee, the flexibility often justifies the cost for investors seeking broader diversification. If you want maximum control and the ability to invest beyond stocks and mutual funds, MySolo401k Financial offers one of the most customizable solo 401k solutions available.
7. Rocket Dollar Solo 401k
Rocket Dollar focuses on self-directed retirement accounts, including solo 401k plans for business owners. Its main advantage is the ability to invest in nearly any asset class, from real estate to startups and crypto. The platform simplifies the paperwork and compliance process for alternative investments. There are setup and monthly fees, which may be higher than traditional brokerages, but the flexibility can be worth it. Entrepreneurs who want true investment freedom and are comfortable managing alternative assets often find Rocket Dollar’s solo 401k structure highly attractive.
8. Ubiquity Retirement + Savings
Ubiquity Retirement + Savings provides customizable 401k plans tailored to small businesses and self-employed individuals. Unlike standard brokerage-based solo 401k plans, Ubiquity focuses more on plan administration and compliance support. This can be valuable for business owners who want hands-off management and professional oversight. Fees vary depending on plan features, and investment flexibility depends on the custodian selected. Ubiquity is ideal for entrepreneurs who prefer structured guidance and administrative support rather than managing every detail themselves, especially as their businesses grow and retirement planning becomes more complex.
9. Nabers Group Solo 401k
Nabers Group specializes in self-directed solo 401k plans with an emphasis on checkbook control. This structure allows business owners to make investment decisions quickly without custodian approval for each transaction. The plan supports real estate, private lending, and other alternative investments, along with Roth contributions and participant loans. There are upfront and annual fees, but many investors value the autonomy it provides. For entrepreneurs seeking full control over retirement funds and interested in non-traditional assets, Nabers Group offers a flexible and powerful solo 401k solution.
10. Guideline Solo 401k
Guideline is known for its modern, technology-driven retirement platform. While primarily focused on small business 401k plans with employees, it also offers options suitable for solo business owners. The interface is clean, automated, and easy to use, making compliance and administration simpler. Fees are transparent, and investment options typically include diversified ETF portfolios. Guideline is a good fit for tech-savvy entrepreneurs who appreciate automation and simplicity. If you plan to eventually hire employees and expand your retirement benefits, starting with a provider like Guideline may offer a smooth transition.
Conclusion
Choosing the best solo 401k provider depends on your business structure, investment style, and long-term financial goals. If you prefer low fees and traditional investments, major brokerages like Fidelity, Schwab, or Vanguard may be ideal. If you want alternative assets and maximum flexibility, specialized self-directed providers like MySolo401k or Rocket Dollar could be better suited. As a business owner, your retirement plan is one of your most powerful wealth-building tools. Compare fees, features, and investment options carefully, and select a solo 401k provider that aligns with your growth strategy and risk tolerance.
