SIMPLE IRA or SEP IRA: Which Is Right for My Small Business?
Last reviewed: July 2026
The choice between a SIMPLE IRA vs SEP IRA comes down to who funds the plan and how many people you employ. A SIMPLE IRA lets both you and your employees contribute, with required employer matching, and works well for businesses with up to 100 employees. A SEP IRA is funded entirely by the employer and shines for solo operators or owners with very few staff who want higher contribution ceilings. If you have employees and want them saving alongside you, SIMPLE usually wins. If you're a one-person shop chasing the biggest deduction, SEP often pulls ahead.
Key Takeaways
- A SIMPLE IRA allows employee salary deferrals up to $17,000 in 2026, while a SEP IRA is employer-funded only.
- A SEP IRA permits contributions up to $72,000 in 2026, far above SIMPLE limits, making it strong for high-earning solo owners.
- SIMPLE IRAs require employer contributions every year; SEP IRA contributions are discretionary and can be skipped in lean years.
- SEP IRA contributions must be the same percentage for every eligible employee, which gets expensive as your staff grows.
About the Author: Jeff Judge, CFP®, AEP®, ChFC®, CLU® is Managing Partner of Chesapeake Financial Planners in Forest Hill, Maryland. He has been helping families and business owners in Harford County and the Baltimore metro area navigate small business retirement plans since earning his CFP® certification in 2013, by using Chesapeake Financial Planners’ signature process, the R.U.D.D.E.R. method™. Jeff has watched plenty of owners pick a plan based on a friend's recommendation, only to discover two years later that the contribution math worked against them.
What Is the Difference Between a SIMPLE IRA and a SEP IRA?
The core difference is who puts money in. A SIMPLE IRA (Savings Incentive Match Plan for Employees) lets employees defer part of their salary into the account, and the employer is required to match. A SEP IRA (Simplified Employee Pension) is funded entirely by the employer, with no employee contributions allowed at all.
That single distinction drives almost every decision that follows. If you want your team building their own retirement savings, SIMPLE creates that structure. If you'd rather control all the funding yourself and skip years when cash is tight, SEP gives you that flexibility.
Both plans skip the heavy paperwork and annual testing that come with a traditional 401(k). According to the IRS, a SIMPLE IRA has no annual Form 5500 filing requirement, which keeps administrative costs low. That's a real advantage for owners who don't want to hire a third-party administrator.
In Jeff's experience working with Harford County business owners, the simple ira vs sep ira question almost always resolves once you answer one thing first: do you have employees you want to include, or are you funding only yourself?

How Much Can I Contribute to a SIMPLE IRA vs a SEP IRA in 2026?
This is where the two plans separate the most. The contribution ceilings are not close.
For a SIMPLE IRA in 2026, employees can defer up to $17,000, per the IRS. Workers age 50 and older can add a catch-up contribution of $4,000. Thanks to SECURE 2.0, those aged 60 through 63 get an enhanced catch-up of $5,250 in 2026. On top of the employee deferral, the employer either matches dollar-for-dollar up to 3% of pay or makes a 2% nonelective contribution for all eligible workers.
For a SEP IRA in 2026, the employer can contribute up to 25% of each employee's compensation, capped at $72,000. There are no employee deferrals and no catch-up contributions for those over 50, because the entire account is employer-funded.
| Feature | SIMPLE IRA (2026) | SEP IRA (2026) |
|---|---|---|
| Who contributes | Employee + employer | Employer only |
| Employee deferral limit | $17,000 | Not allowed |
| Catch-up (age 50+) | $4,000 | None |
| Max total contribution | ~$20,000 with match | $72,000 |
| Employer contribution | Required every year | Discretionary |
| Best for | Businesses with employees | Solo owners or very few staff |
The takeaway: a high-earning solo business owner can stuff far more into a SEP IRA than a SIMPLE allows. But that ceiling only helps if you have the income to fill it.
Which Plan Is Better If I Have Employees?
If you have W-2 employees, the SIMPLE IRA usually fits better, and the reason is cost. With a SIMPLE IRA, your required contribution is a match. If an employee defers nothing, you owe nothing on the match formula (though the 2% nonelective option does require contributions regardless).
A SEP IRA flips that math against you. Under SEP rules, you must contribute the same percentage of compensation for every eligible employee that you contribute for yourself. So if you want to put 20% of your own pay into a SEP, you have to put 20% of every eligible employee's pay in too. With a handful of staff, that gets expensive fast.
Here's where Jeff Judge often tells clients to slow down. An owner sees the $72,000 SEP ceiling and gets excited, then realizes that matching that generosity across six employees could cost tens of thousands more per year than a SIMPLE would. The plan with the higher ceiling isn't automatically the cheaper plan.
The Department of Labor notes that both plans require you to cover eligible employees fairly, so neither lets you carve out only yourself once you have a team. Plan for the full cost before you sign.

When Does a SEP IRA Make More Sense?
A SEP IRA wins in a few clear situations. The most common is the solo business owner with no employees, where the proportional-contribution rule costs you nothing because you're the only person in the plan.
SEP also makes sense when your income swings year to year. SEP contributions are discretionary. You can contribute 20% in a strong year and zero in a slow one. A SIMPLE IRA, by contrast, requires an employer contribution every single year you run the plan, which can pinch during a downturn.
The third scenario is the high earner who wants maximum deduction now. A consultant netting $200,000 with no staff can shelter a large chunk of income through a SEP that a SIMPLE simply can't match. According to the IRS, self-employed individuals calculate their SEP contribution on net earnings after the self-employment tax deduction, so the working figure is a bit lower than gross, but the ceiling is still far above SIMPLE.
This is exactly the kind of trade-off the R.U.D.D.E.R. Method™ is built to surface. The R.U.D.D.E.R. Method™ is Chesapeake Financial Planners' six-step planning process: Review and Recognize, Uncover and Understand, Design and Develop, Discuss and Decide, Execute and Empower, and Reassess and Refine. The "Uncover and Understand" step is where we map your real cash flow against each plan's required commitments before anyone picks a structure.
Should I Choose a Solo 401(k) or SEP IRA for My Business?
Can I Switch From a SIMPLE IRA to a SEP IRA Later?
Yes, but timing matters. A SIMPLE IRA must generally be your only retirement plan during the calendar year you run it, so you typically can't run a SIMPLE and a SEP in the same year. To switch, you usually terminate the SIMPLE at year-end and start the SEP the following January.
There's a notice rule worth knowing. Per the IRS, you must notify employees during the election period (generally November 2 through December 31) if you plan to discontinue the SIMPLE for the coming year. Skip that notice and you may be locked in for another year.
This is a spot where owners trip themselves up. Jeff has seen a business owner decide in March to move to a SEP, only to learn the window to exit the SIMPLE had closed months earlier. The lesson: revisit your plan choice in the fall, not the spring.

Frequently Asked Questions
What is the main difference between a SIMPLE IRA and a SEP IRA?
The main difference is funding. A SIMPLE IRA allows both employee salary deferrals and required employer contributions, while a SEP IRA is funded entirely by the employer with no employee contributions permitted. SIMPLE suits businesses with employees who want to save; SEP suits solo owners or those wanting maximum employer-funded contributions.
Can I have both a SIMPLE IRA and a SEP IRA in the same year?
Generally no. A SIMPLE IRA must be the only retirement plan your business maintains during the calendar year you operate it. To switch from a SIMPLE to a SEP, you typically terminate the SIMPLE at year-end, provide proper employee notice, and start the SEP the following January for a clean transition.
How much can a self-employed person contribute to a SEP IRA in 2026?
A self-employed person can contribute up to 25% of net earnings (after the self-employment tax deduction) to a SEP IRA in 2026, capped at $72,000 per the IRS. Because the calculation uses net rather than gross income, the effective rate works out to roughly 20% of net self-employment earnings.
Does a SIMPLE IRA require me to contribute every year?
Yes. A SIMPLE IRA requires an employer contribution every year you maintain the plan, either a dollar-for-dollar match up to 3% of pay or a 2% nonelective contribution for all eligible employees. This mandatory funding is a key difference from a SEP IRA, where employer contributions are fully discretionary year to year.
Which plan is cheaper for a business with several employees?
A SIMPLE IRA is usually cheaper for a business with several employees. Under SEP rules you must contribute the same percentage for every eligible worker that you contribute for yourself, which scales costs quickly. A SIMPLE match only funds employees who defer, often making it the lower-cost option for staffed businesses.
What are the SIMPLE IRA contribution limits for 2026?
For 2026, employees can defer up to $17,000 into a SIMPLE IRA, per the IRS. Workers age 50 and older may add a $4,000 catch-up contribution. Under SECURE 2.0, employees aged 60 through 63 qualify for an enhanced catch-up of $5,250, raising their total deferral capacity for those specific years.
