For freelancers, consultants, and small business owners, planning for retirement can be a daunting task. The unpredictability of income often complicates the process of saving for the future. However, the introduction of the solo 401(k) offers a tailored solution for those who work independently.
A solo 401(k) is specifically designed for self-employed individuals or business owners who have no full-time employees other than themselves and possibly their spouse.
This innovative retirement plan functions similarly to a traditional 401(k), allowing for both employee and employer contributions. Its unique structure provides flexibility that surpasses other retirement savings options, such as SEP IRAs or SIMPLE IRAs.

Understanding the solo 401(k)
Many self-employed workers often underestimate the simplicity and advantages of a solo 401(k). This retirement plan is not only accessible to high-income earners but also beneficial for individuals across various income levels. With a solo 401(k), you can maximize your contributions during lucrative years while adjusting them down when your income decreases.
Tax advantages and contribution limits
One of the most significant benefits of a solo 401(k) is its generous contribution limits. In 2025, you can potentially contribute up to $70,000, not including any catch-up contributions for those aged 50 and above. This higher threshold allows for substantial tax-deferred growth, making it an attractive option for retirement savings.
Another appealing feature is the opportunity to make contributions for your spouse, if applicable. By contributing to the solo 401(k) using their earnings from your business, you can effectively double your retirement savings and further reduce your household’s taxable income through pre-tax contributions.
Setting up your solo 401(k)
Choosing the right provider is crucial for an efficient solo 401(k) setup. Look for a financial institution that prioritizes transparency in fees and offers user-friendly digital tools. Additionally, consider providers that present a range of financial services, enabling you to manage your financial portfolio conveniently from one platform.
Catch-up contributions and late setup options
Thanks to the SECURE Act 2.0, you can establish a solo 401(k) after the start of the new year and still make contributions for the prior year. For instance, if you set up your plan in March 2025, you can still contribute towards 2024 until your tax filing deadline. This feature allows you to catch up on any missed retirement savings opportunities.
Moreover, if you’re over 50, you can benefit from additional catch-up contributions, enhancing your retirement savings even further. Starting in 2026, any catch-up contributions must be allocated to a Roth solo 401(k) if your prior year’s income exceeded $145,000, providing a strategic way to save while managing your tax obligations.
Comparing solo 401(k)s with other retirement plans
As a self-employed individual, you might wonder how a solo 401(k) stacks up against other retirement accounts like SEP IRAs. While both options offer high contribution limits, the solo 401(k) provides more avenues for contributions. For example, if your income fluctuates, you can contribute as both an employee and employer, giving you greater flexibility in your savings strategy.
In contrast, SEP IRAs restrict contributions to employer funds only, which can cap the amount you can save based on your income. This limitation can be a disadvantage for those who wish to maximize their retirement contributions.
