If you’re self-employed or running a small business, you’ve probably felt the tension between investing in your company and investing in your future.
A SEP IRA is one of the simplest ways to do both.
These retirement accounts were designed specifically for people like you: business owners, freelancers, and sole proprietors who need high contribution limits without the headache of managing a complex retirement plan.
The contribution ceiling for 2026 alone is $72,000, which makes a traditional IRA’s $7,500 cap look tiny.
Whether you’re a one-person shop or you employ a handful of people, understanding how SEP retirement accounts work can be the difference between retiring comfortably and scrambling to catch up later.
This guide walks through the essentials for small businesses and self-employed workers: eligibility, contributions, tax perks, setup, and the rules that trip people up most often.
Article Highlights:
- SEP IRAs let small business owners and self-employed individuals contribute up to $72,000 in 2026, dwarfing traditional IRA limits.
- Only employers make contributions, and the same percentage must apply to all eligible employees.
- Setup is straightforward: complete IRS Form 5305-SEP, open accounts, and notify your team.
- Contributions are tax-deductible for the business and grow tax-deferred for participants until withdrawal.
Understanding Simplified Employee Pension (SEP) IRAs
A Simplified Employee Pension IRA is an employer-funded retirement account that allows business owners to make tax-deductible contributions directly into IRAs established for themselves and their eligible employees.
The key word there is “employer-funded.”
Unlike a 401(k), employees don’t contribute their own salary. The business makes all the deposits, which simplifies administration dramatically.
SEP IRAs were created to give small businesses access to a retirement savings vehicle that doesn’t require annual IRS filings, nondiscrimination testing, or the administrative overhead that comes with qualified plans.
As James Blake, VP of ADP Broker-Dealer Operations, puts it: “A SEP IRA offers small business owners and self-employed individuals a simple, flexible way to save for retirement – with high contribution limits and upfront tax benefits. They are easy to set up and can scale with your business.”
That scalability matters.
In a strong revenue year, you can max out contributions. In a lean year, you can contribute nothing. There’s no mandatory annual contribution, which gives you breathing room that most other retirement plans don’t.
How a SEP IRA Differs from a Traditional IRA
The most obvious difference is the contribution limit.
Traditional IRAs cap contributions at $7,500 in 2026, with a $1,100 catch-up for those 50 and older. SEP IRAs allow up to $72,000 for the same year. That’s nearly ten times the savings potential.
Another distinction: traditional IRAs are funded by the individual, while SEP IRAs are funded entirely by the employer.
Even if you’re self-employed and you are the employer, the contribution comes from the business side of the equation, not your personal income. This matters for how deductions are calculated on your tax return.
Traditional IRA deductions can also phase out based on income if you or your spouse are covered by a workplace plan, but SEP contributions don’t face that same phase-out issue.
Primary Benefits for the Self-Employed and Small Business Owners
For freelancers, consultants, and small business owners, a SEP IRA checks several boxes at once.
You get high contribution limits, minimal paperwork, and flexible funding. There’s no requirement to contribute every year, so your retirement savings can flex with your income.
Small businesses may also be eligible for a tax credit of up to $5,000 per year for the first three years to offset the cost of starting a SEP plan. That’s money back in your pocket just for setting up the account.
And because contributions reduce your taxable business income, the tax savings compound: you’re building retirement wealth while lowering your current tax bill.
Eligibility Requirements for Employers and Employees
Not every business or worker automatically qualifies for a SEP IRA. The IRS has specific rules about who can establish a plan and who must be included.
IRS Criteria for Business Owners
Any business entity can set up a SEP IRA: sole proprietorships, partnerships, LLCs, S-corps, C-corps, and even nonprofit organizations.
There’s no minimum or maximum business size. A freelance graphic designer working from their kitchen table has the same access as a 20-person accounting firm.
The critical requirement is that you have self-employment income or business income to fund the contributions.
If your business didn’t generate a profit, you can’t contribute.
And if you’re a sole proprietor, your contribution is based on net self-employment income after deducting half of your self-employment tax, which we’ll cover in the contribution section.
Statutory Requirements for Employee Participation
Here’s where things get important for business owners with staff.
If you have employees who meet the IRS eligibility criteria, you must include them in the plan. You can’t set up a SEP IRA just for yourself and exclude qualifying workers.
An employee is eligible if they are at least 21 years old, have worked for the business in at least three of the last five years, and have earned at least $800 in 2026. For 2025, that minimum compensation threshold was $750. These thresholds are adjusted periodically for inflation.
The equal contribution rule is non-negotiable: whatever percentage of compensation you contribute for yourself, you must contribute the same percentage for every eligible employee.
If you put in 20% of your own compensation, every qualifying team member gets 20% of theirs too.
This is the single biggest factor that makes some business owners with multiple employees look at other plan types instead.
Contribution Limits and Calculation Rules
The contribution math for SEP IRAs is straightforward in concept but has a few quirks worth understanding, especially for self-employed individuals.
Annual Percentage and Dollar Caps
For 2026, employers can contribute up to 25% of an employee’s compensation or a maximum of $72,000, whichever is less. Compensation used for the calculation is capped at $360,000 in 2026, so even if an employee earns $500,000, you’d calculate the contribution based on $360,000.
For W-2 employees, the math is clean: multiply their compensation by whatever percentage you choose (up to 25%), and that’s the contribution.
For a business owner paying themselves a $200,000 salary through an S-corp, a 25% contribution would be $50,000.
The 25% Compensation Rule Explained
Self-employed individuals face a slightly different calculation.
You can’t simply take 25% of your gross self-employment income. Instead, you first reduce your net earnings by half of your self-employment tax, then apply the contribution percentage to that adjusted figure.
The effective maximum rate for sole proprietors and partners works out to roughly 20% of net self-employment income rather than 25%.
Here’s a practical example…
Say your Schedule C shows $150,000 in net profit. After deducting half of your self-employment tax (approximately $10,597), your adjusted net self-employment earnings are about $139,403. At the effective 20% rate, your maximum SEP contribution would be roughly $27,881.
It’s less than the $37,500 you might expect from a straight 25% calculation, but it’s still significantly more than you could put into a traditional IRA.
Tax Advantages and Deductions
The tax benefits of a SEP IRA work on two levels: immediate deductions for the business and long-term tax-deferred growth for the account holder.
Tax-Deductible Business Contributions
Every dollar you contribute to a SEP IRA is deductible as a business expense.
For sole proprietors, this deduction appears on your personal tax return (Form 1040, Schedule 1) as an adjustment to income. For corporations, it’s a deductible business expense on the corporate return. Either way, it directly reduces taxable income.
If you’re in the 32% federal tax bracket and contribute $50,000 to your SEP IRA, that’s $16,000 in federal tax savings alone, not counting state taxes.
The deduction is available regardless of whether you itemize, which makes it accessible to virtually everyone.
Tax-Deferred Growth for Participants
Once contributions land in the SEP IRA, investment gains compound without annual taxation. You won’t pay taxes on dividends, interest, or capital gains until you withdraw the money.
Over 20 or 30 years, that tax-deferred compounding can add hundreds of thousands of dollars compared to investing in a taxable brokerage account.
One recent development worth knowing about: the SECURE Act 2.0 made Roth SEP IRAs possible, combining high contribution limits with tax-free withdrawals in retirement.
With a Roth SEP, you pay taxes on contributions now but never pay taxes on qualified withdrawals later. For younger business owners expecting higher future tax rates, this can be a powerful planning tool.
Step-by-Step Guide to Setting Up a SEP Plan
Setting up a SEP IRA is one of the easiest things you’ll do as a business owner. The entire process can be completed in an afternoon.
Executing a Formal Written Agreement (Form 5305-SEP)
You need a formal written agreement to establish the plan.
The simplest approach is to use IRS Form 5305-SEP, which is a model plan document the IRS provides for free. Fill it out, keep it in your records, and you’re done. You don’t file it with the IRS.
Alternatively, many brokerage firms (Fidelity, Schwab, Vanguard) provide their own SEP plan documents that you complete when opening the account. The process typically involves:
- Choosing a financial institution for the accounts
- Completing the plan adoption agreement
- Opening a SEP IRA account for yourself and each eligible employee
- Funding the accounts
There are no annual IRS filings required for a SEP IRA, which is a major advantage over 401(k) plans that require Form 5500 each year.
Notifying Eligible Employees
You must provide each eligible employee with a copy of the completed Form 5305-SEP (or your institution’s equivalent) and information about the plan.
Employees need to know that a SEP IRA has been established on their behalf, how contributions work, and what their rights are regarding the funds.
Each employee owns their SEP IRA account outright. There’s no vesting schedule.
Once you deposit money into an employee’s SEP IRA, it belongs to them immediately. They control the investment choices within their account, and they take the account with them if they leave your company.
Comparing SEP IRAs with Solo 401(k)s and SIMPLE IRAs
Choosing between a SEP IRA, a Solo 401(k), and a SIMPLE IRA depends on your specific situation. Here’s how they stack up:
- A Solo 401(k) allows both employee deferrals and employer contributions, potentially letting you save more at lower income levels. It also permits Roth contributions directly. However, it’s only available to business owners with no employees (other than a spouse), and it requires Form 5500-EZ once assets exceed $250,000.
- A SIMPLE IRA works for businesses with 100 or fewer employees and has mandatory employer contributions (either a 3% match or 2% non-elective contribution). The 2026 employee deferral limit is lower than a 401(k), and the plan has a two-year waiting period before rollovers to other IRAs are penalty-free.
- A SEP IRA wins on simplicity and high contribution limits but lacks employee deferral options and requires equal percentage contributions for all eligible employees.
If you’re a solo freelancer earning over $60,000, a Solo 401(k) often lets you shelter more income at lower earnings levels.
If you have employees and want the simplest possible plan, the SEP IRA is hard to beat. The right choice depends on your income level, employee count, and how much administrative work you’re willing to handle.
Deadlines for Contributions and Plan Maintenance
One of the most attractive features of a SEP IRA is its generous contribution deadline.
You can make SEP IRA contributions for the 2026 tax year as late as your business tax filing deadline, including extensions.
For sole proprietors, that means April 15, 2027, or October 15, 2027, if you file an extension.
This gives you months of additional time compared to traditional IRA contributions, which must be made by the April tax deadline without extensions. It also means you can wait until you know your exact income for the year before deciding how much to contribute. That kind of flexibility is rare in retirement planning.
Ongoing maintenance is minimal.
There are no annual filings, no compliance testing, and no required employer contributions in any given year. You simply decide each year whether and how much to contribute.
Withdrawal Rules and Early Distribution Penalties
SEP IRA withdrawal rules mirror those of traditional IRAs.
Withdrawals before age 59½ are generally subject to income tax plus a 10% early distribution penalty. There are exceptions for disability, certain medical expenses, first-time home purchases (up to $10,000), and a few other qualifying events.
Once you reach 59½, you can take distributions without the penalty, though you’ll still owe ordinary income tax on every dollar withdrawn.
SEP IRAs also require minimum distributions starting at age 73, which means you can’t let the money grow indefinitely.
You’ll need to start drawing down the account according to IRS life expectancy tables.
For those thinking about tax-efficient withdrawal sequencing in retirement, SEP IRA funds are typically drawn after taxable accounts but before Roth accounts.
Strategic Roth conversions during lower-income years can help reduce the eventual RMD burden and give you more control over your tax picture in retirement.
At Hero Retirement, we think about this through the Returns pillar of our HERO framework (Health, Enjoyment, Returns, Opportunity): it’s not just about accumulation but about keeping more of what you’ve built.
Your Next Step: Start Before the Deadline
A SEP IRA remains one of the most powerful and underused retirement tools available to small business owners and self-employed workers.
The combination of high contribution limits, tax deductibility, minimal paperwork, and flexible funding makes it a strong fit for anyone with variable business income who wants to build serious retirement wealth.
The best part?
You can establish and fund a SEP IRA all the way up to your tax filing deadline, so there’s still time to make a meaningful contribution for this tax year. Don’t let another year pass without putting your business profits to work for your future self.
Frequently Asked Questions
Can I have a SEP IRA and a traditional IRA at the same time?
Yes. SEP IRA contributions don’t affect your ability to contribute to a traditional or Roth IRA. However, having a SEP IRA means you’re covered by an employer plan, which may limit the deductibility of your traditional IRA contributions depending on your income.
What happens to my SEP IRA if I close my business?
The money stays in your SEP IRA account. You own it. You can leave it invested, roll it into a traditional IRA, or convert it to a Roth IRA. Closing the business doesn’t trigger any penalties or forced distributions.
Can I contribute to a SEP IRA if I also have a full-time job with a 401(k)?
Yes, if you have qualifying self-employment income on the side. Your SEP IRA contribution is based solely on your self-employment earnings and is separate from your 401(k) contributions at your day job.
Do I have to contribute the same amount every year?
No. SEP IRA contributions are entirely discretionary. You can contribute the maximum one year and nothing the next. The only rule is that whatever percentage you choose in a given year must apply equally to all eligible employees.
