Small business owners often face the important decision of selecting the right retirement plan to help themselves and their employees secure a stable financial future. Two popular options tailored for small businesses in the United States are the SEP IRA (Simplified Employee Pension) and the SIMPLE IRA (Savings Incentive Match Plan for Employees). While both provide tax benefits and retirement savings opportunities, they have distinct structures, contribution rules, and administrative requirements. Understanding these differences is crucial for choosing the most suitable plan for your business.
What is a SEP IRA?
A SEP IRA allows employers to make tax-deductible contributions directly to individual retirement accounts for themselves and their eligible employees. Only employers contribute to SEP IRAs; employees cannot defer salary into the plan. Contribution limits are relatively high — for 2023, contributions can be up to 25% of an employee’s compensation or $66,000, whichever is less (adjusted annually for inflation by the IRS). Contributions must be proportional for all eligible employees, meaning if you contribute 10% of your salary, you must do the same for eligible staff.
What is a SIMPLE IRA?
In contrast, a SIMPLE IRA allows both employer and employee contributions. Employees can defer a portion of their salary up to $15,500 for 2023, with an additional catch-up contribution of $3,500 if they are age 50 or older. Employers are required to either match employee contributions dollar-for-dollar up to 3% of compensation or contribute a fixed 2% of pay regardless of employee contributions. SIMPLE IRAs are designed for businesses with 100 or fewer employees, making it ideal for smaller companies wanting employee involvement in retirement savings.
Eligibility Requirements
- SEP IRA: Any size business can adopt a SEP IRA. Eligible employees are typically those aged 21 or older who have worked for the business at least three of the last five years and earned at least $750 during the year.
- SIMPLE IRA: Reserved for businesses with 100 or fewer employees. Employees who earned $5,000 or more in the previous calendar year are eligible to participate.
Contribution and Employer Involvement
SEP IRAs provide maximum flexibility with discretionary employer contributions each year, allowing businesses to adjust based on profitability. This flexibility can benefit seasonal businesses or those with fluctuating income. On the other hand, SIMPLE IRAs involve mandatory employer contributions—either matching contributions or fixed percentages—encouraging consistent employer participation in employee retirement savings.
Administrative Requirements
SEP IRAs have minimal administrative duties, with no annual filing requirements to the IRS. Contributions are straightforward to execute, reducing paperwork and complexity.
SIMPLE IRAs require employers to provide employees with an annual notice outlining plan details and must file Form 5500-SF if the plan exceeds 100 participants. Additionally, SIMPLE IRA setup involves a formal adoption process using IRS Form 5304-SIMPLE or 5305-SIMPLE.
Early Withdrawal Penalties
Both plans impose a 10% federal tax penalty on withdrawals taken before age 59½. However, SIMPLE IRAs carry a higher early distribution penalty of 25% if the withdrawal occurs within the first two years of participation, which is designed to discourage early cash-outs.
Real-World Example
Consider a small bakery with five employees:
- With a SEP IRA, the owner can decide annually whether to contribute, and if so, must contribute the same percentage of salary for all eligible employees. If the owner contributes 10%, each employee receives 10% of their pay as a contribution.
- With a SIMPLE IRA, employees can elect to defer part of their salary into the plan. The employer then matches contributions up to 3% or contributes 2% of pay automatically, regardless of employee participation.

Choosing Between SEP IRA and SIMPLE IRA
- Opt for a SEP IRA if you want flexible, potentially larger employer-only contributions without employee deferrals.
- Choose a SIMPLE IRA if you want to encourage employee savings with payroll deductions and are ready to commit to mandatory employer contributions and more administrative steps.
- Your business size and cash flow should also influence your choice. SIMPLE IRAs are limited to 100 or fewer employees, while SEP IRAs can fit any business size.
Common Pitfalls
- Confusing the two plans as interchangeable; they have different rules around contributions and employer obligations.
- Ignoring eligibility criteria can lead to compliance issues.
- Overlooking the elevated early withdrawal penalties in SIMPLE IRAs during the initial two years.
- Underestimating mandatory employer contributions’ impact on budget with SIMPLE IRAs.
