If you are self-employed, there is no HR department automatically enrolling you in a retirement plan or depositing an employer match. You are responsible for deciding how much to save, where to invest it, and how retirement contributions fit with the cash flow of your business.
A Simplified Employee Pension, commonly called a SEP IRA, can make that process easier. It is designed for self-employed professionals, freelancers, independent contractors, and small-business owners who want relatively high contribution potential without the administrative requirements of a traditional corporate retirement plan.
For 2026, SEP contributions can reach $72,000, subject to compensation and contribution-percentage limits. However, the calculation works differently for a sole proprietor than it does for an S-corporation owner, and having employees can significantly affect the cost of the plan.
Understanding those rules before making a contribution can help you take advantage of the SEP without accidentally exceeding the limit or overlooking contributions required for eligible employees.
What Is a SEP IRA?
A SEP is an employer-sponsored retirement arrangement that allows a business to make contributions to IRAs established for eligible participants.
For a self-employed person with no employees, you effectively wear both hats: you are the employer establishing the SEP and the participant receiving the contribution.
SEP plans are popular because they combine several useful features:
- High Contribution Potential: The annual SEP limit can be substantially higher than the regular Traditional or Roth IRA contribution limit.
- Flexible Annual Funding: The employer generally can contribute more during a profitable year and contribute less, or nothing, during a slower year.
- Relatively Simple Administration: A SEP is generally easier to operate than many qualified retirement plans and typically does not require the same annual Form 5500 filing associated with certain other plans.
- Immediate Vesting: SEP contributions belong to participants immediately rather than becoming vested gradually over several years.
The simplicity becomes especially valuable for a freelancer or business owner whose income changes significantly from one year to the next.
What Is the SEP IRA Contribution Limit for 2026?
For 2026, employer contributions to a participant’s SEP IRA generally cannot exceed the lesser of:
- 25% of eligible compensation, or
- $72,000
The maximum compensation that can generally be considered when determining a SEP contribution for 2026 is $360,000.
That does not mean every self-employed person can simply deposit $72,000. Your actual limit depends on your business structure, compensation, net earnings, and whether you have eligible employees.
2026 SEP IRA Limits at a Glance
| SEP Rule | 2026 Amount |
| Maximum SEP contribution | $72,000 |
| Maximum employee compensation considered | $360,000 |
| Maximum employer contribution rate | 25% |
| SEP minimum compensation for eligibility | $800 |
| Age-50 catch-up contribution | None for a regular SEP |
A regular SEP also does not permit employee elective salary deferrals like a 401(k). The contributions are employer contributions, although a self-employed person effectively makes the contribution for themselves as the business owner.
How Much Can a Sole Proprietor Contribute to a SEP IRA?
For a sole proprietor or independent contractor, the calculation is more complicated than simply multiplying net business profit by 25%.
Your SEP contribution is based on net earnings from self-employment, adjusted for the deductible portion of self-employment tax and the contribution itself.
Because the SEP contribution reduces the compensation on which the contribution percentage is calculated, a 25% plan contribution rate generally translates into an effective maximum rate of approximately 20% of adjusted net self-employment earnings for the self-employed owner.
The basic process is:
- Determine your net profit from self-employment.
- Reduce it by the deductible portion of self-employment tax.
- Apply the self-employed SEP contribution calculation.
- Make sure the result does not exceed the $72,000 maximum for 2026.
Suppose a consultant has $150,000 of business profit. The SEP contribution would not simply be 25% of $150,000, or $37,500. The calculation first needs to account for the applicable self-employment tax adjustment and the special self-employed contribution formula.
This is why self-employed business owners should use the current SEP worksheet or tax software rather than applying 25% directly to Schedule C profit.
How Do SEP Contributions Work for an S Corporation?
An S-corporation owner follows a different calculation because the SEP contribution is generally based on W-2 compensation paid by the corporation, not business distributions.
If your S corporation pays you $120,000 of eligible W-2 wages, a 25% employer contribution could generally reach $30,000.
If the same business distributes an additional $100,000 to you as an S-corporation shareholder distribution, that distribution does not create another $25,000 of SEP contribution capacity.
This distinction can be important for business owners who keep W-2 salary relatively low while taking substantial shareholder distributions.
The contribution still cannot exceed the annual $72,000 SEP maximum for 2026.
Can an LLC Use a SEP IRA?
Yes. An LLC may be able to establish a SEP, but the contribution calculation depends on how the LLC is taxed.
A single-member LLC taxed as a sole proprietorship generally follows the self-employed calculation based on adjusted net earnings. An LLC electing S-corporation taxation generally bases the owner’s SEP contribution on eligible W-2 wages.
A partnership has another layer of rules because partners are treated as self-employed individuals for retirement-plan purposes. The partnership establishes the SEP rather than each partner establishing a separate SEP for partnership income.
Your legal business structure therefore does not tell the entire story. The tax treatment of the business determines which SEP contribution calculation applies.
What Happens if Your Business Has Employees?
A SEP can become significantly more expensive when a business has eligible employees.
If you contribute the same percentage of compensation to your own SEP account, eligible employees generally must receive the same contribution percentage under the plan’s allocation formula.
For example, if you decide to contribute 15% of eligible compensation for yourself, you generally cannot give yourself 15% while contributing only 5% for another employee who is eligible under the same SEP terms.
That makes a SEP extremely attractive for many solo business owners but potentially less attractive for a growing company with several employees.
Before establishing a SEP, calculate not only how much you want to contribute for yourself but also what the same contribution percentage could cost across your eligible workforce.
Who Is Eligible for a SEP?
A SEP can generally use eligibility requirements that include employees who:
- Have Reached Age 21
- Worked for the Employer in at Least Three of the Previous Five Years
- Receive at Least $800 in Compensation During 2026
An employer can use less restrictive requirements. For example, a business could allow employees to participate before age 21 or after a shorter period of service.
The employer generally cannot use eligibility requirements that are more restrictive than the permitted SEP limits.
The same participation rules also apply to an owner. A business owner cannot create restrictive rules that exclude employees while ignoring those same requirements for themselves.
Can You Skip a SEP Contribution in a Bad Business Year?
Yes. One of the major advantages of a SEP is that employer contributions are generally discretionary from year to year.
If business income is strong, you may decide to make a substantial contribution. If profits fall or the business needs additional cash, you may contribute a smaller percentage or choose not to make a contribution for that year.
If you do contribute, however, eligible participants generally must receive contributions according to the plan’s allocation formula.
This flexibility can make a SEP particularly useful for consultants, contractors, and business owners whose income is unpredictable.
What Is the SEP IRA Contribution Deadline?
A SEP offers more flexibility than many workplace retirement plans because the plan can generally be established and funded as late as the due date of the business’s federal income-tax return, including extensions.
The exact deadline therefore depends on how your business is taxed and whether you requested an extension.
A sole proprietor filing Schedule C with an individual return may have a different extended deadline from an S corporation or partnership. For that reason, it is better to follow your actual business tax-return deadline rather than relying on one universal date such as October 15.
This can be valuable because you may know your final business profit before deciding how much to contribute.
For example, instead of committing to a large contribution during an uncertain year, you can review the completed financial results and then determine what contribution fits your cash flow and tax strategy.
Are SEP IRA Contributions Tax-Deductible?
Traditional SEP contributions generally provide a business tax deduction subject to the applicable deduction rules.
For a sole proprietor, the owner’s SEP deduction is generally reported with the individual return rather than deducted directly as a Schedule C business expense.
An S corporation generally deducts eligible employer SEP contributions on its corporate return.
The money contributed to a traditional SEP IRA can then grow tax-deferred until distributions begin.
Withdrawals from a traditional SEP IRA generally follow Traditional IRA tax rules. Taxable distributions are usually included in ordinary income, and withdrawals before age 59½ can potentially face the federal 10% additional early-distribution tax unless an exception applies.
Can a SEP IRA Have Roth Contributions?
Yes. This is an important change from older SEP guidance.
Federal law now permits Roth SEP IRA contributions when the SEP arrangement and financial institution support the feature. That means the old statement that SEP IRAs can only receive pre-tax employer contributions is no longer universally accurate.
With a traditional SEP contribution, the contribution generally receives pre-tax treatment and future taxable withdrawals are included in income.
A Roth SEP contribution instead receives Roth tax treatment. The participant generally recognizes the contribution as income rather than receiving the traditional pre-tax benefit, while qualified future Roth distributions can potentially be tax-free.
Not every SEP provider necessarily implements Roth SEP contributions in the same way, so confirm availability with the institution administering the plan before assuming the feature is offered.
Does a SEP IRA Allow Catch-Up Contributions?
A regular SEP does not provide the age-50 catch-up contribution available in many 401(k) plans. That means turning 50, 60, or 63 does not increase the $72,000 SEP contribution ceiling simply because of age.
This is one area where a Solo 401(k) can have an advantage for a business owner with no common-law employees. A Solo 401(k) can allow employee elective deferrals in addition to employer contributions and can provide catch-up contribution opportunities for eligible older participants.
If maximizing contributions late in your career is a major priority, compare both structures rather than assuming a SEP is automatically the better option because it is simpler.
SEP IRA vs. Solo 401(k): Which Is Better?
Both accounts can work well for self-employed business owners, but they create retirement contributions differently.
A SEP IRA generally relies on employer contributions. A Solo 401(k) allows an eligible owner to contribute both as an employee and as the employer.
For 2026, the basic employee 401(k) elective-deferral limit is $24,500. Eligible participants age 50 or older can have additional catch-up capacity, while the overall defined contribution limit is generally $72,000 before applicable catch-ups.
That can make a Solo 401(k) particularly useful when business income is moderate because the employee contribution component may allow you to reach a higher total contribution at a lower level of income.
A SEP can still be attractive when simplicity, flexible employer funding, and reduced administration are the priorities.
RetireNova’s 401(k) contribution limits guide provides more detail on the current workplace-plan limits.
Can You Have a SEP IRA and Another Retirement Plan?
Potentially, yes.
For example, someone who works as an employee for one company and also earns income through an unrelated self-employed business may participate in the employer’s retirement plan while establishing a SEP for the separate business.
The interaction between plan limits depends on whether the businesses are related, which employer sponsors each plan, and the type of contribution being made.
It is therefore not accurate to assume that every dollar contributed to a 401(k) at another unrelated employer automatically reduces the amount your separate business can contribute to a SEP.
Rules become more complicated when businesses are under common control or when more than one retirement plan is maintained by the same employer.
If you have several businesses or workplace retirement plans, check the contribution limits before funding the accounts rather than assuming each plan automatically receives an entirely separate maximum.
Can You Also Contribute to a Traditional or Roth IRA?
Yes, if you are otherwise eligible.
An employer SEP contribution does not by itself use up your regular personal IRA contribution limit.
For 2026, the combined regular Traditional and Roth IRA contribution limit is $7,500, with an additional $1,100 catch-up for individuals age 50 or older.
Roth IRA eligibility is also subject to income phaseouts, while the deductibility of a Traditional IRA contribution can depend on income and retirement-plan coverage.
This means a self-employed individual may potentially use a SEP for business retirement savings while also making a personal IRA contribution under the separate IRA rules.
What Happens to a SEP IRA in Retirement?
A traditional SEP IRA generally follows many of the same distribution rules as a Traditional IRA.
Withdrawals are generally taxable as ordinary income to the extent they consist of pre-tax contributions and earnings. Early distributions can potentially face the additional 10% federal tax unless an exception applies.
Traditional SEP IRAs also eventually become subject to required minimum distributions.
Under current law, the applicable RMD starting age generally depends on birth year. People born from 1951 through 1959 generally have an RMD age of 73, while people born in 1960 or later generally have an RMD age of 75.
If a large SEP balance becomes an important part of your retirement savings, understanding required minimum distributions and the rules by age can help you plan future withdrawals before they become mandatory.
Common SEP IRA Mistakes to Avoid
A SEP is simpler than many retirement plans, but the contribution rules still create opportunities for expensive mistakes.
Watch for these common issues:
- Using 25% of Schedule C Profit Directly: Self-employed individuals must use the special net-earnings calculation rather than simply multiplying business profit by 25%.
- Using an Outdated Contribution Limit: The maximum SEP contribution is $72,000 for 2026, not the $69,000 figure that applied in 2024 or the $70,000 limit for 2025.
- Ignoring Eligible Employees: A business owner generally cannot make a generous percentage contribution for themselves while excluding employees who meet the plan’s eligibility requirements.
- Assuming SEP Catch-Ups Exist: Regular SEP plans do not provide additional age-50 catch-up contribution room.
- Using S-Corp Distributions as Compensation: SEP contributions for an S-corporation owner are based on eligible W-2 wages rather than shareholder distributions.
- Assuming SEP Contributions Must Be Traditional: Roth SEP contributions are now permitted when the plan and provider support them.
Reviewing these rules each year is especially important as your business income, employee count, or tax structure changes.
How Should a SEP Fit Into Your Retirement Strategy?
The ability to contribute up to $72,000 does not mean the goal should always be to reach the maximum.
Your business still needs cash for taxes, emergency reserves, operating expenses, growth, and personal spending. A very large retirement contribution that leaves the business financially strained may not improve your overall position.
Think about the SEP alongside your other retirement assets, Social Security, expected retirement date, and future income needs.
A self-employed professional approaching retirement may also need to shift attention from how much goes into the SEP toward how those accumulated assets will eventually create sustainable income.
RetireNova’s retirement income and withdrawal planning can help connect today’s business contributions with the income those assets may later need to provide.
FAQs
What is the SEP IRA contribution limit for 2026?
The maximum SEP contribution for 2026 is generally the lesser of 25% of eligible compensation or $72,000.
How much can a self-employed sole proprietor contribute?
The calculation is based on adjusted net earnings from self-employment. Because the contribution itself affects the calculation, the effective maximum rate is generally about 20% rather than simply 25% of Schedule C profit.
What is the maximum compensation used for a SEP in 2026?
Up to $360,000 of eligible compensation can generally be considered when calculating a 2026 SEP contribution.
Can an S-corporation owner use distributions to calculate the SEP contribution?
No. SEP contributions for an S-corporation owner generally are based on eligible W-2 wages. Shareholder distributions do not count as compensation for calculating the SEP employer contribution.
Does a SEP IRA have an age-50 catch-up contribution?
No. A regular SEP does not allow the age-based catch-up contributions available through certain other retirement plans.
Can a SEP IRA have Roth contributions?
Yes. Federal law now allows Roth SEP IRA contributions when the plan and financial institution support the feature.
Can I contribute to both a SEP and a Roth IRA?
Potentially, yes. Employer SEP contributions do not automatically use your regular individual IRA contribution limit. Your Roth IRA contribution is still subject to its separate annual limit, compensation requirement, and income phaseouts.
When is the SEP IRA contribution deadline?
SEP contributions generally can be made through the due date of the employer’s federal income-tax return, including extensions. The specific date depends on your business structure and tax-return deadline.
Do I have to contribute to a SEP every year?
Generally, no. SEP employer contributions can be discretionary from year to year. However, when a contribution is made, eligible employees generally must be treated according to the plan’s contribution formula.
