Simple IRA vs SEP IRA: Pros & Cons Explained

As individuals journey through their careers and grow older, planning for retirement becomes increasingly important. Two popular retirement saving options are Simple IRAs and SEP IRAs, which offer distinct advantages and disadvantages to both employers and employees. Navigating through the complexities of these retirement plans can be challenging, but having a thorough understanding of their features, requirements, and potential benefits will allow you to make informed decisions that best align with your financial goals.

Understanding Simple IRAs

One key aspect of Simple IRAs is their purpose and eligibility requirements for both employers and employees. Simple IRAs, or Savings Incentive Match Plan for Employees, are designed to offer a retirement savings plan for small businesses with 100 or fewer employees. This type of plan is advantageous for small business owners as it lessens the financial burden on the company, compared to a traditional 401(k) plan. To qualify for a Simple IRA, employees must have earned at least $5,000 in the past year and expect to earn another $5,000 in the upcoming year. Both employers and employees need to meet these eligibility requirements for the plan to be an option for the business.

Another important point in understanding Simple IRAs is the contribution limits associated with this type of plan. Employees can contribute up to $13,500 in 2021, or $16,500 if they are over the age of 50. These limits are lower than those for traditional 401(k)s, but still offer employees an opportunity to save for retirement. In contrast, a Simplified Employee Pension (SEP) IRA has significantly higher contribution limits, with the 2021 limit set at $58,000 or 25% of the employee’s compensation, whichever is less. This can be advantageous for self-employed individuals or small business owners earning a high income and seeking to maximize their retirement contributions.

One benefit of Simple IRAs is the presence of employer matching. Under a Simple IRA, employers can choose between two different matching options: a dollar-for-dollar match of employee contributions up to 3% of the employee’s salary or a 2% non-elective employer contribution for all eligible employees, regardless of whether the employee contributes to the Simple IRA. This employer match offers an incentive for employee participation in the retirement plan, and encourages employees to save for their future. SEP IRAs, on the other hand, do not require or allow for employer matching contributions, which can result in lower overall contributions for employees in comparison to Simple IRA plans.

When it comes to setting up a Simple IRA, the process is relatively straightforward. Employers can choose a financial institution to handle the administration of the plan. Once the chosen institution is in place, the employer and financial institution collaborate to create a written plan document that outlines the details of the Simple IRA. The employer then notifies eligible employees about the Simple IRA, provides them with enrollment materials, and establishes procedures for payroll deductions. This setup process is generally more streamlined and cost-effective in comparison to a traditional 401(k) plan, which can make it a suitable option for small businesses.

As employers work to provide their employees with retirement benefits, a key decision they face is whether to choose a Simple IRA or a SEP IRA. Both options have unique advantages that cater to different business situations and employee needs. While the SEP IRA’s higher contribution limits are often more attractive to high earners, the Simple IRA may provide a more cost-effective solution for small businesses with its lower administrative costs and employer-matching contributions. Comparing the features of both Simple and SEP IRAs helps employers make an informed decision on the most suitable retirement savings plan for their workforce.

Understanding SEP IRAs

When considering retirement savings options, SEP IRAs and SIMPLE IRAs can both be appealing choices for small businesses and self-employed individuals. The Simplified Employee Pension (SEP) IRA is a retirement plan that allows employers to make tax-deductible contributions to their employees’ IRAs. The primary purpose of SEP IRAs is to provide an easy-to-manage and cost-effective retirement savings plan for small businesses with minimal administrative requirements.

To be eligible to establish a SEP IRA, an employer must have earned income and must not have any other employer-sponsored retirement plan. Employees who meet the eligibility criteria – which typically includes being at least 21 years old, having worked for the employer in at least three of the previous five years, and having earned at least $600 during the current year – can participate in the plan. The flexibility of SEP IRAs allows employers to choose whether or not to contribute to their employees’ retirement accounts each year, making it an attractive option for businesses with variable income.

Compared to SIMPLE IRAs, SEP IRAs generally offer higher contribution limits, which can be particularly advantageous for those looking to save more for their retirement. For 2021, the maximum contribution limit for a SEP IRA is the lesser of 25% of an employee’s compensation or $58,000. In contrast, the maximum contribution limit for a SIMPLE IRA is $13,500 for employees under 50 and $16,500 for those 50 or older. This can make SEP IRAs more appropriate for businesses with higher-earning employees who want to maximize their retirement savings.

Another benefit of SEP IRAs is their flexible funding options. Employers have the discretion to decide how much they want to contribute each year, and the contribution rates can even vary among employees. Additionally, the deadlines for funding SEP IRA accounts are more lenient, allowing employers and self-employed individuals to make contributions up until their tax filing deadline, including extensions. This flexibility can be particularly helpful for businesses experiencing fluctuating financial circumstances.

Establishing a SEP IRA involves relatively simple steps. First, the employer needs to complete and sign an IRS Form 5305-SEP, which provides a written agreement detailing eligibility requirements, contribution rates, and other plan information. Once this form is completed, the employer must provide a copy to each eligible employee and open individual SEP-IRAs for them at the chosen financial institution. Compared to other retirement plan options like the 401(k), SEP IRAs have fewer reporting requirements and lower administrative costs, which can be particularly advantageous for small business owners.

Pros and Cons of Simple IRAs

On the other hand, SIMPLE IRAs have their unique advantages that may be more suitable for certain businesses or individuals. One clear advantage of a SIMPLE IRA over a SEP IRA is the ease of setup and lower administrative costs. This makes SIMPLE IRAs an attractive retirement plan for small businesses and self-employed individuals who prioritize more straightforward setup processes and minimal paperwork requirements. As an employer, this means less time spent on retirement plan management and more time to focus on growing and maintaining business operations.

While SEP IRAs offer higher contribution limits for businesses with higher-earning employees, SIMPLE IRAs may still be a better fit for smaller companies or those with more modest incomes. Both options have their advantages and disadvantages, and the choice ultimately depends on the business’s needs and financial circumstances. It is essential to weigh the pros and cons of each retirement savings plan to determine which is the best fit for the business and its employees.

In terms of employer contributions, Simple IRAs may present both pros and cons. On the positive side, employers are required to either match employee contributions up to 3% of an employee’s salary or make non-elective contributions of 2% for all eligible employees, regardless of employee contributions. This aspect of Simple IRAs can serve as an incentive for employees to participate in the plan and may help with employee retention and satisfaction. However, this mandatory contribution requirement could be viewed as a disadvantage for employers who may not be in a financial position to make consistent contributions to their employees’ retirement accounts.

From the employee perspective, the ability to make contributions to a Simple IRA can be an advantage compared to a SEP IRA. Whereas SEP IRAs are funded solely through employer contributions, Simple IRAs allow employees to contribute to their retirement plans via salary deferrals on a pre-tax basis. This feature of Simple IRAs enables employees to take greater control over their retirement savings and reduces their taxable income for that year, a perk that is absent in SEP IRAs.Another potential drawback of a Simple IRA is the limitation on contributions and employer matching compared to a SEP IRA. In 2021, the annual contribution limit for Simple IRAs is $13,500 for employees under 50 ($13,000 in 2020), significantly lower than the $58,000 limit for SEP IRAs. This lower cap on contributions may be a disadvantage for employees with higher incomes who wish to maximize their retirement savings. Furthermore, since employer matching is capped at 3% in Simple IRAs, employees who can save more may not reap the full benefits of employer matching, leading them to miss out on potential increased retirement savings.In conclusion, Simple IRAs and SEP IRAs each possess their own unique set of restrictions that may impact their suitability depending on the specific circumstances. For example, Simple IRAs are solely accessible to employers having 100 or fewer employees, and the obligatory contribution prerequisite might not be appropriate for certain businesses. In contrast, SEP IRAs are often viewed as being more adaptable due to their allowance for variable annual contribution rates. However, this characteristic may not be advantageous to all employees, particularly if an employer opts for lower or irregular contribution sums. In the end, determining whether to choose a Simple IRA or a SEP IRA depends on the particular needs and preferences of the employer and employee, and a comprehensive understanding of both options can contribute to a well-informed decision.

Pros and Cons of SEP IRAs

One notable advantage of a SEP IRA (Simplified Employee Pension Individual Retirement Account) for employers is the flexibility it offers regarding contributions. Employers can elect to contribute up to 25% of an employee’s compensation or $58,000 in 2021 (whichever is less) without committing to a fixed percentage every year. This enables employers to modify contributions based on the company’s financial performance, which can be especially beneficial for small businesses with fluctuating revenues. Conversely, employees may benefit from potentially higher contribution limits compared to a SIMPLE IRA (Savings Incentive Match Plan for Employees Individual Retirement Account), which only permits a maximum annual employee contribution of $13,500 in 2021.Another pro of SEP IRAs is the simplified administration compared to other retirement plans. While both SEP and SIMPLE IRAs require minimal paperwork and reporting, the SEP IRA is easier to set up, typically with lower fees. This can be especially attractive to employers who seek a cost-effective retirement plan with minimal administrative burdens. In addition, both employers and employees can benefit from the tax advantages that come with a SEP IRA, such as tax-deductible contributions and tax-deferred growth.However, there are also some limitations to SEP IRAs that can pose challenges for both employers and employees. One of the major drawbacks is the lack of employee participation in contributions. Unlike SIMPLE IRAs, which allow employees to contribute to their accounts via elective salary deferrals, SEP IRA contributions can only be made by the employer. This may mean that employees who would like to contribute more to their retirement savings may feel limited by a SEP IRA plan.

Another potential con of a SEP IRA is the requirement for employers to make proportional contributions for all eligible employees. This means that if an employer decides to contribute to their own SEP IRA or that of a key employee, they must also contribute an equal percentage of salary for all other eligible employees. This can lead to higher overall costs for the employer, which is one of the reasons many small business owners may opt for a SIMPLE IRA instead.

One potential downside of a SEP IRA (Simplified Employee Pension) is the limited eligibility for some employees. Generally, employees must be at least 21 years of age, have worked for the employer for a minimum of three out of the last five years, and have received at least $650 in compensation in 2021 to be eligible for a SEP IRA plan. This could result in certain employees being unable to participate in this retirement plan, which may be a drawback for employers who seek to offer a retirement savings option to their entire staff.

Comparing Simple and SEP IRAs

When comparing SIMPLE IRAs and SEP IRAs, it is important to evaluate the unique features of each retirement plan in relation to employer and employee needs, company size, and tax implications. SIMPLE IRAs, also known as Savings Incentive Match Plan for Employees, are employer-sponsored retirement plans catered to small businesses with 100 or fewer employees. These plans require employers to contribute a percentage of employee salaries, either through matching contributions up to 3% or a flat 2% non-elective contribution for all eligible workers. In contrast, SEP IRAs cater to self-employed individuals and small businesses of any size. With SEP IRAs, employers have the ability to make tax-deductible contributions to employee accounts without being obligated to make mandatory contributions. This flexibility can be a determining factor when choosing between the two retirement plan options.

The tax implications for both Simple and SEP IRAs are similar, with contributions being tax-deductible for employers and tax-deferred growth for employees. However, there are some key differences in contribution limits. For Simple IRAs, employees may contribute up to $13,500 in 2021 ($16,500 for those age 50 and over), while the maximum employer contribution is 3% of employee compensation. On the other hand, SEP IRAs allow employers to contribute up to 25% of an employee’s compensation, with a maximum limit of $58,000 in 2021. This higher contribution limit may make SEP IRAs more attractive to businesses seeking to maximize retirement savings and tax deductions.

In terms of employer administration and costs, Simple IRAs are generally considered easier and less expensive to set up and maintain compared to other employer-sponsored retirement plans such as 401(k)s. They do not require annual filing with the IRS and are relatively straightforward to administer. Meanwhile, SEP IRAs also have low startup and maintenance costs, and employers can easily adjust their contributions based on business performance. This flexibility can be a significant advantage for businesses with fluctuating revenues or for self-employed individuals who might need to adjust their contributions based on their income.

With respect to employee access to funds, both Simple and SEP IRAs allow for early withdrawals before age 59½, albeit with a 10% IRS penalty in most cases. However, Simple IRA participants face an even steeper 25% penalty for withdrawals made within the first two years of the account’s existence, which may be a considerable disadvantage for employees who might need access to funds in emergency situations. Conversely, SEP IRA rules do not differentiate between long-term and short-term participation, and early withdrawals are subject only to the standard 10% penalty.

When considering retirement savings options for your business, it is essential to evaluate the specific needs and goals of your enterprise and employees. Two popular retirement savings plans often compared are the Simplified Employee Pension (SEP) IRA and the Savings Incentive Match Plan for Employees (SIMPLE) IRA. Both can provide significant tax benefits to you and your employees, but each has its unique set of advantages and disadvantages depending on your business structure, employee makeup, and financial objectives.

Choosing the Right IRA for Your Business

In summary, when assessing Simple and SEP IRAs, it is important to consider the unique features and requirements of each plan in relation to your individual or company’s specific needs. Simple IRAs are generally better suited for small businesses with consistent employer contribution levels, while SEP IRAs offer greater flexibility and higher contribution limits for employers, making them an attractive choice for the self-employed and businesses with fluctuating revenues. Both plans offer similar tax advantages and are relatively easy to administer, but employees should be aware of potential restrictions and penalties when it comes to accessing funds early.


For small business owners who are self-employed or have few employees, SEP IRA may offer a straightforward and flexible option. This plan allows the employer to contribute up to 25% of each employee’s compensation (or $58,000 for 2021, whichever is lower) directly to the employee’s SEP IRA account. Contributions are tax-deductible for the business and not considered taxable income for employees; however, employees cannot contribute to their SEP IRA accounts personally. The plan’s flexibility allows employers to adjust their contribution levels each year, making it a suitable choice for businesses with variable cash flow.


On the other hand, SIMPLE IRA plans are designed for businesses with 100 or fewer employees and allow both employer and employee contributions. Employers can either match employee contributions on a dollar-for-dollar basis up to 3% of the employee’s compensation, or contribute a flat 2% of each eligible employee’s pay, regardless of whether they contribute to the plan or not. Employee contributions are capped at $13,500 for 2021, with an additional catch-up contribution limit of $3,000 for employees aged 50 or over. While employee contribution limits are lower in SIMPLE IRAs than other retirement plans like 401(k)s, SIMPLE IRAs have fewer administrative requirements, making them more appealing to small business owners.

Employee Eligibility and Participation

Another factor that may influence your decision between a SEP IRA and SIMPLE IRA is employee eligibility and participation. To be eligible for a SEP IRA, employees must be at least 21 years old, have worked for the company in at least three of the last five years, and earned a minimum of $600 in the current year. SIMPLE IRA plans have less stringent eligibility requirements, as employees only need to have earned $5,000 in any two previous calendar years and expect to earn at least $5,000 in the current calendar year. Employers must also remember that they cannot offer other retirement plans, like a 401(k), alongside a SIMPLE IRA.


Ultimately, the choice between a SEP IRA and SIMPLE IRA comes down to your business’s specific needs and objectives. If your company has a small pool of high-income employees, a SEP IRA may provide a more attractive solution due to its higher employer contribution limits and adaptability. In contrast, SIMPLE IRAs offer the advantage of employee involvement and may better suit businesses looking to provide a more inclusive retirement savings opportunity with less administrative hassle. Examining your business structure, employee dynamics, and financial goals will be crucial to determining the best retirement plan for both you and your staff.

Ultimately, the decision between a Simple IRA and a SEP IRA depends on an individual’s or business’s unique needs, goals, and circumstances. It is crucial to meticulously evaluate each plan’s pros and cons, and to consult with a financial professional if necessary, in order to make the most suitable choice for your retirement saving strategy. By taking the time to understand the various aspects of these retirement plans, you’ll be setting yourself or your employees on the path to a more secure and prosperous future.
