If you’re self-employed or own a small business, you have unique options for retirement savings beyond the traditional 401(k) or IRA. One popular choice is the SEP IRA (Simplified Employee Pension Individual Retirement Account). A SEP IRA is a retirement plan that allows business owners to contribute to retirement for themselves and their employees with higher limits and flexible funding. They are known for being easy to administer, which is great for entrepreneurs. However, SEP IRAs also come with some restrictions and potential downsides to consider. In this article, we’ll break down the general benefits of a SEP IRA and the disadvantages so you can determine if it’s the right plan for you or your business.
What is a SEP IRA?
A SEP IRA is a type of retirement plan established by an employer (typically a self-employed person, small business owner, or freelancer) for themselves and potentially their employees. “SEP” stands for Simplified Employee Pension. It basically functions like a Traditional IRA in terms of tax treatment – contributions are tax-deductible (as a business expense for the employer), investments grow tax-deferred, and withdrawals in retirement are taxed as income. However, the contribution limits for SEP IRAs are much higher than for a personal IRA. In a SEP, only the employer can contribute – employees do not contribute from their salary. If you’re self-employed, you’re both the employer and employee, so essentially you contribute to your own SEP IRA.
Key points of how a SEP works: - Every eligible employee (including the owner) has their own SEP IRA account set up (usually at a brokerage or financial institution). The employer decides each year how much to contribute for each employee. - Contributions are made by the employer for each employee, and must be proportional to their compensation. For example, if you decide to contribute 10% of salary for yourself, you must also contribute 10% of each eligible employee’s salary into their SEP IRA. - Contributions are discretionary each year. One major benefit is that you can choose to contribute a lot in good profit years and little or nothing in lean years. There’s no required annual contribution. This flexibility is why many cyclical businesses like SEPs. SEP IRAs follow the same investment rules as regular IRAs–funds can be invested in stocks, bonds, mutual funds, etc. No fancy stuff like life insurance or collectibles, similar to normal IRA restrictions. Employees are always 100% vested in their SEP IRA money immediately. That means once you contribute, the money belongs to the employee (there’s no vesting schedule as with some 401k matches). If the employee leaves, they take their SEP IRA with them (it’s just an IRA in their name).
Now, let’s look at the pros and cons of this type of plan.
Benefits of a SEP IRA
• High Contribution Limits: One of the biggest advantages of a SEP IRA is the ability to contribute much more each year than to a regular IRA. For 2025, a business owner can contribute up to 25% of an employee’s compensation, or $70,000, whichever is less. (For 2024 the dollar cap was $69,000; these limits increase with inflation). In practical terms, if you’re a sole proprietor with a good income, you could potentially sock away tens of thousands in a SEP, far above the $7k limit of a personal IRA. This makes SEPs a powerful tool for catching up on retirement savings or reducing taxable income. For example, if you (as the business owner) have a $100,000 net income from self- employment, you might contribute around $18,000–$20,000 to your SEP (since self-employed use a special calculation ~20% of net profit). Higher income can hit the max easily (e.g., at $300k income you’d hit the $70k cap, since 25% of $300k is $75k but the cap limits it). High contribution limits are a key reason people choose SEP IRAs – you can really accelerate retirement savings in good years 20 .
• Tax Deductibility and Lower Taxes Now: Contributions to a SEP IRA are generally tax-deductible as a business expense. This means every dollar you put into the plan lowers your taxable profit. For a sole proprietor, SEP contributions are taken as an above-the-line deduction on your tax return. For an incorporated business, they’re a deductible expense on the business books. Either way, you’re effectively lowering your current tax bill by saving for retirement. This is a win-win. Over time, the investments grow tax-deferred (no taxes each year on interest, dividends, or gains). You’ll pay taxes when you withdraw in retirement, but ideally at that time you might be in a lower tax bracket. In the meantime, you got a tax break up front. For instance, a $20,000 SEP contribution could save a self- employed person perhaps $4,000–$6,000 in taxes (depending on their tax bracket and state taxes).

• Flexible Annual Contributions: With a SEP, you are not obligated to contribute every year. You can skip contributions entirely in a year if finances are tight, or vary the amount. This flexibility is valuable for small businesses with fluctuating income. For example, if you have no profit one year, you simply don’t contribute. There are no penalties or required minimum funding like some other plans. Contrast this with a SIMPLE IRA or certain pension plans that might require fixed contributions or matches – a SEP lets you decide each year. It’s “good if cash flow is an issue,” as the IRS notes.
• Ease of Setup and Low Admin Costs: As the name implies (“Simplified”), SEP IRAs are straightforward to establish and maintain. You can open a SEP plan by filling out a simple one-page form (IRS Form 5305-SEP) or adopting a brokerage’s prototype plan document. There’s no annual IRS filing required by the employer (unlike a 401(k) which requires Form 5500 filings for larger plans). Administration is minimal – essentially just fund the contributions and give employees an annual statement of what was contributed. Most banks or brokerages that offer IRAs also offer SEP IRAs, and they often charge little or no extra fees for them. This simplicity and low cost make SEPs very attractive to small businesses that don’t have the resources for a complex plan. It’s truly as easy as opening IRAs for employees and deciding on contributions each year.
• Employee Morale and Retirement Benefit: If you have employees, a SEP IRA can serve as a nice benefit that helps attract and retain talent. While you aren’t required to contribute every year, when you do, you’re effectively giving your employees a profit-sharing bonus that goes into their retirement. Employees immediately own those contributions (vested) and can see their retirement savings grow. Small businesses often can’t afford to offer a full 401(k) with matching; a SEP is a simpler way to do something for your employees’ futures. It also has an advantage that employees don’t contribute from their pay – some might see that as a con (no salary deferral), but others might appreciate that whatever goes in is entirely from the company. From the business owner perspective, contributions are discretionary and only made when affordable, which manages cost.
• Concurrent Personal IRA: Having a SEP IRA doesn’t prevent you from also contributing to a personal Traditional or Roth IRA. You can do both (though if you contribute to a Traditional IRA, the deductibility might be affected by being covered by a plan). Also, you can have a SEP IRA and other plans: e.g., you could also contribute to a Roth 401(k) at a day job and still do a SEP for your side business. There are some aggregation rules, but generally a SEP offers an additional avenue to save.
In summary, SEP IRAs provide high limits, flexibility, tax breaks, and simplicity – all great benefits for a small business owner or self-employed individual.
Drawbacks and Disadvantages of a SEP IRA
• Employer-Funded Only (No Employee Contributions): With a SEP, employees cannot contribute from their own salaries. This is a disadvantage if you (or your employees) want to defer more of your own pay toward retirement. In a 401(k), for example, an employee can elect to save part of their paycheck (and the owner can too, as an employee of their business), but a SEP doesn’t allow that. So if an employee wants to save extra, they’d need to do it in their own IRA separate from the SEP. For the owner, this means you can’t do the “employee deferral” portion you could in, say, a solo 401(k). You’re limited to employer contributions only. That’s usually fine if your income is high enough (you’ll reach the max anyway), but for some it’s a limitation.
•Must Include All Eligible Employees Equally: SEP IRAs have little flexibility in covering employees – if you set one up, you generally have to include all employees who are at least 21 years old, have worked for you 3 of the last 5 years, and earned at least a minimal amount ($750 in 2023, inflation-adjusted) 22 . You also must contribute the same percentage of compensation for each eligible employee 23 . For example, if you (the owner) want to contribute 20% of your pay to your SEP, you must also contribute 20% of each eligible worker’s pay to their SEP IRAs. This can become expensive if you have multiple employees. There is no option to only cover yourself or exclude certain employees (aside from those who don’t meet eligibility criteria). Moreover, if you contribute for yourself in a year, you have to contribute for them as well at the same rate – you can’t give yourself 25% and employees 10%, for instance. This equal percentage rule is a major drawback for business owners with staff; it’s very generous to employees, but it might limit how much you want to contribute (because contributing a high percentage for everyone could be unaffordable). Some owners in this situation might look at alternative plans (like a 401k or SIMPLE IRA) that allow or require more cost-sharing from employees.
No Catch-Up Contributions for 50+: Unlike 401(k)s or Traditional/Roth IRAs, SEP IRAs do not permit catch-up contributions for those over age 50 24 . The limit is the limit for everyone. For example, in a 401k someone over 50 gets an extra $7,500 to defer; in a personal IRA an extra $1,000. In a SEP, there’s no such extra – the same $69k cap applies, regardless of age. This is a minor issue since the regular limit is already high, but if you’re older and want to turbocharge savings, a solo 401(k) might allow you to contribute more in combination (through deferrals + profit-sharing + catch-up).
No Roth Option: SEP contributions are pre-tax only; there is no built-in Roth SEP IRA feature 25 . All contributions go in tax-deductible and will be taxed on withdrawal. Some newer 401(k) plans allow Roth contributions; SEP IRAs do not. If you desire Roth money (tax-free in retirement), you’d have to later convert some of the SEP funds to a Roth IRA, which is an extra step and triggers tax on the conversion. So, SEP is somewhat less flexible in this regard. (Note: There is talk in the industry about whether legislation might eventually allow “Roth SEP” contributions, but as of now it’s not standard.)
Required Minimum Distributions: A SEP IRA, like any Traditional IRA, is subject to required minimum distributions starting at age 73 (for current retirees) or 75 in the future 26 . This means you can’t keep the money growing indefinitely – you’ll have to start drawing it down and paying taxes at that point. This is the same as any pre-tax plan, so it’s not unique to SEP, but worth noting. Roth IRAs by contrast have no RMDs for the original owner.
Early Withdrawal Penalties: Again, like any retirement account, pulling money out of a SEP IRA before age 591⁄2 will incur a 10% early withdrawal penalty (plus taxes) unless you meet an exception 27 . There’s no special loan provision or hardship withdrawal built into SEP IRAs as some 401(k)s have. Essentially, once money is in a SEP, it should stay until retirement or you’ll face penalties for taking it out too soon (with a few exceptions such as first-time homebuyer $10k, etc., which apply to IRAs). This isn’t really a disadvantage compared to other retirement accounts – more of a general caveat: don’t contribute money you might need in the short term.
Less Employee Control/Portability: Because employees themselves don’t contribute to a SEP, some might feel less engaged with the plan. Also, while an employee absolutely can roll over or transfer their SEP IRA when leaving the company (it’s an IRA, so very portable), the contributions are solely employer-driven. If you have employees who would rather save through payroll, they may prefer a 401(k) or SIMPLE IRA environment. That said, an employee can always separately open their own IRA to save personally; it just won’t be through payroll deduction.
In short, the drawbacks of SEP IRAs include lack of employee input (all contributions on employer), required equal contributions for employees (costly for multi-employee businesses), no Roth or catch-up features, and the standard retirement account restrictions on withdrawals. For one-person businesses or those with just a spouse as an employee, most of these drawbacks are minimal – which is why SEPs are especially popular for freelancers and very small businesses. For those with several employees, the proportional contribution requirement is the big factor to carefully consider.
Recommendation: A SEP IRA can be a great solution for a self-employed individual or a business owner with few or no employees. It offers high contribution potential with minimal fuss. If you do have employees, weigh the cost of contributing for them – sometimes a SIMPLE IRA or even a 401(k) might be more appropriate if employees want to contribute on their own or if you need more flexibility in contributions. If your priority is maximizing your own savings and you have no employees (or only high-earning employees where giving them the same percentage is acceptable), the SEP IRA is hard to beat for simplicity and impact. Green Musa Capital can help you compare SEP vs. Solo 401(k) vs. other plans to see which gives you the best outcome. Remember that whatever plan encourages you to save the most for retirement (without jeopardizing your business cash flow) is a winner.
