As a small business owner, your ability to plan for retirement while managing tax efficiency is one of the smartest financial strategies you can employ. However, the variety of retirement plans available can feel overwhelming. Two of the most popular retirement savings vehicles for small business owners are the SEP IRA and the Solo 401(k). Each offers distinct advantages depending on your income, business size, and long-term goals.
In this guide, we’ll explore the SEP IRA and Solo 401(k) in detail, comparing them based on contributions, tax benefits, and suitability for different business structures.
What is a SEP IRA?
A Simplified Employee Pension (SEP) IRA is a retirement plan designed for self-employed individuals and small business owners. It’s straightforward, easy to set up, and offers significant tax-deferred growth potential.
Key Features of a SEP IRA:
Eligibility: Employers (including sole proprietors) can set up SEP IRAs for themselves and their employees. There are no age restrictions for participation.
Contribution Limits: For 2024, contributions can be up to 25% of an employee’s compensation or $70,000, whichever is less. For self-employed individuals, contributions are calculated based on net earnings after expenses and self-employment taxes.
Tax Benefits: Contributions are tax-deductible, reducing taxable income for the year they are made. Investments grow tax-deferred until withdrawal.
Ease of Administration: Minimal paperwork and no ongoing compliance testing make SEP IRAs a simple option for small business owners.
However, SEP IRAs require uniform contributions. If you contribute 25% of your salary to your own SEP IRA, you must contribute the same percentage for all eligible employees.
What is a Solo 401(k)?
A Solo 401(k) is a retirement savings plan designed for self-employed individuals and small business owners with no employees (other than a spouse). It offers higher contribution limits and additional tax-saving opportunities compared to a SEP IRA.
Key Features of a Solo 401(k):
Eligibility: You must have no employees other than yourself (and possibly a spouse). Part-time or freelance help generally doesn’t count.
Contribution Limits: For 2024, the total contribution limit is $70,000, with an additional $7,500 in catch-up contributions for individuals aged 50 or older. Contributions are divided into:
Employee Deferral: Up to $23,500 or 100% of compensation, whichever is less.
Employer Profit Sharing: Up to 25% of net self-employment income.
Tax Benefits: Contributions can be pre-tax (reducing taxable income) or Roth (allowing for tax-free growth). Investments grow tax-deferred or tax-free, depending on the account type.
Loan Feature: You can borrow up to $50,000 or 50% of the account balance, whichever is less.
Administrative Requirements: Solo 401(k)s require more paperwork than SEP IRAs. Once your account reaches $250,000, you must file Form 5500 annually with the IRS.
The Solo 401(k) is highly customizable, allowing you to optimize for tax savings, retirement savings, or a mix of both.

Feature | SEP IRA | Solo 401(k) |
Eligibility | Business owners and employees | Self-employed with no employees |

Catch-Up Contributions | Not available | $7,500 for those aged 50+ |
Tax Deductibility | Contributions reduce taxable income | Pre-tax or Roth options available |
Ease of Setup | Simple with minimal paperwork | More complex, requires plan setup |
Employee Participation | Uniform contributions required for employees | Not applicable |

Choosing the Right Plan Based on Income, Business Size, and Goals
1. Income Level
If you have a high income, both the SEP IRA and Solo 401(k) allow for substantial contributions. However, the Solo 401(k) provides the ability to contribute more at lower income levels due to the employee deferral component.
Example: With an income of $50,000, you could contribute $23,500 to a Solo 401(k) but significantly less to a SEP IRA (limited to 25% of net income).
2. Business Size
A Solo 401(k) is ideal if you’re the only employee. It allows for flexible contributions and higher limits.
A SEP IRA is better suited if you have multiple employees since it enables you to contribute to their retirement accounts easily. However, the requirement to contribute the same percentage for all employees can become costly as your team grows.
3. Tax Efficiency
If you’re looking to reduce taxable income, both plans are effective. A Solo 401(k) with a Roth option offers additional flexibility by providing tax-free withdrawals in retirement.
SEP IRAs only allow pre-tax contributions, which may not be as advantageous if you anticipate being in a higher tax bracket during retirement.
4. Administrative Preferences
For those who prioritize simplicity, the SEP IRA is a clear winner. It requires less paperwork and no annual reporting.
If you’re comfortable with more administrative responsibilities, the Solo 401(k) provides greater flexibility and features.
Real-World Scenarios: Which Plan Fits You Best?
Scenario 1: High-Earning Solo Entrepreneur
Income: $200,000
Business Structure: Sole Proprietor
Goal: Maximize contributions while reducing taxable income
Best Choice: Solo 401(k). You can contribute up to $23,500 as an employee, plus an employer profit-sharing contribution, potentially reaching the maximum limit of $70,000.
Scenario 2: Consultant with a Few Employees
Income: $150,000
Business Structure: LLC with 2 employees
Goal: Simple setup with employee benefits
Best Choice: SEP IRA. Contributions are easy to calculate and provide employees with a retirement savings option, enhancing job satisfaction and retention.
Scenario 3: Mid-Income Freelancer
Income: $60,000
Business Structure: Sole Proprietor
Goal: Save for retirement while keeping costs low
Best Choice: Solo 401(k). With the employee deferral option, you can contribute more at this income level compared to a SEP IRA.
Key Considerations When Deciding
Future Growth: If you plan to hire employees, a Solo 401(k) might not be the right choice long-term, as it excludes businesses with employees (other than a spouse).
Flexibility: A Solo 401(k) offers more customization and options, such as Roth contributions and loans.
Administrative Comfort: SEP IRAs are easy to set up and maintain, while Solo 401(k)s require more administrative effort but provide greater tax-saving opportunities.
The Bottom Line: SEP IRA or Solo 401(k)?
The choice between a SEP IRA and a Solo 401(k) depends on your specific financial situation and goals. While both plans are excellent tools for building retirement wealth, the Solo 401(k) generally offers more advantages for self-employed individuals with no employees, especially those seeking higher contribution limits and tax flexibility. A SEP IRA, on the other hand, is a straightforward and effective option for small business owners with employees who want an easy-to-administer retirement plan.
