Maximizing Retirement Savings with a Solo 401(k) in 2023

For the self-employed business owner with no employees, a Solo 401(k) plan remains a powerful tool to maximize retirement savings.

Overview of Solo 401(k) for 2023

In 2023, the Solo 401(k) continues to serve as a robust retirement savings vehicle for business owners without employees. Often known by its other names—self-employed 401(k), individual 401(k), or one-participant 401(k)—the Solo 401(k) allows for both employer and employee contributions, providing a higher savings potential than many other plans.

Eligibility and Contributions

If you’re a business owner with no full-time employees other than yourself and possibly your spouse, you’re eligible to harness the benefits of a Solo 401(k). For 2023, the elective deferral limit set by the IRS remains a key figure, allowing significant pretax or after-tax contributions that grow either tax-deferred or tax-free, respectively.

Advantages for Business Owners

  • Tax Efficiency: Contributions reduce your taxable income, potentially placing you in a lower tax bracket.

  • High Contribution Limits: The combined contribution of employee elective deferrals and employer nonelective contributions can reach up to the specified annual limit.

  • Flexibility: There's no mandatory annual contribution, providing flexibility for those with variable income.

  • Loan Options: Participant loans and hardship withdrawals are permitted, offering financial flexibility in emergencies.

Operational Considerations

Despite the many advantages, a Solo 401(k) does require annual filing of Form 5500 once assets exceed $250,000 and may involve higher administrative costs than simpler plans. It’s important to remain aware of the total contribution limits across all retirement plans in which you participate.

Conflicts with Other Strategies

While the Solo 401(k) is comprehensive, it may not be compatible with other retirement strategies like SIMPLE IRAs or SIMPLE 401(k)s, which are geared towards businesses with employees.

Assumptions for 2023 Planning

The assumption for business owners considering a Solo 401(k) in 2023 is the desire to maximize retirement contributions while maintaining flexibility to adjust for varying income levels.

Requirements for Adoption

To adopt a Solo 401(k), ensure you have a plan document in place and understand that no full-time employees can be hired by the business, excluding the owner and spouse. Contributions should adhere to IRS guidelines and limits.


In 2023, the Solo 401(k) stands out for business owners without employees, providing an unmatched combination of high contribution limits, tax advantages, and flexibility. It’s an ideal structure for those who wish to maximize their retirement savings while retaining control over their business finances. As always, consult with a financial advisor to tailor the plan to your specific needs and to stay abreast of any changes in the tax code that may impact your retirement strategy.
