What is Simplified Employee Pension (SEP) IRA?
A SEP IRA is a retirement plan that lets an employer make tax-deductible contributions into an employee’s individual retirement account.
Unlike a 401(k) or SIMPLE IRA, employees do not make salary deferrals into the plan. The employer decides whether to contribute each year and how much to contribute, up to the legal limit.
It is popular with small businesses and self-employed people because it is simple, flexible, and allows much higher annual contributions than a regular IRA.
A SEP IRA usually takes
- Less administration than a 401(k),
- Has immediate vesting and
- Gives business owners a straightforward way to build retirement savings while reducing taxable income.
How a SEP IRA Works
Once a SEP plan is established, the employer decides each year whether to contribute and, if so, what percentage of compensation to use.
If the employer contributes for one eligible worker, it must use the same percentage for all eligible workers.
1. Determine eligible employees
Use plan rules up to IRS minimums to list eligible employees.
All eligible employees who worked during the year must receive the contribution, even if they leave mid-year.
2. Set contribution rate
Choose a uniform percent (0–25%) of each employee’s compensation, they are subject to IRS caps.
3. Calculate contributions
For each eligible person, compute plan compensation and multiply by the chosen percentage.
If they are a salaried employee, the plan compensation is generally their pay.
For a self-employed owner, plan compensation is net business earnings minus half of the self-employment tax and minus the owner’s SEP contribution.
4. Make contributions by the deadline
Next, deposit each employee’s contribution into their SEP-IRA by the due date of the employer’s tax return.
Deposits can be made up to that deadline and still apply to the previous tax year.
5. Claim the tax deduction
The employer deducts the contributions as a business expense on its tax return
- Schedule C for sole proprietors
- Corporate return for C-corporations, etc.
Employees pay no tax on the contributions when made, and their tax is deferred until distribution.
The money then grows tax-deferred inside each person’s IRA.
Who Should Use a SEP IRA
SEP IRAs are attractive because they are simple.
They usually involve
- Minimal paperwork
- No employee salary deferrals, and
- No annual nondiscrimination testing.
They are also very flexible, since employers can contribute more in profitable years and skip contributions in lean years.
So, it makes them a good fit for businesses with uneven cash flow and lets them save a lot when they want to, without locking them into a rigid annual commitment.
Contribution limits
SEP IRA contributions are generous compared with standard IRAs.
| SEP IRA Contribution Limits (2026) | Amount | What It Means |
|---|---|---|
| Maximum employer contribution | Lesser of 25% of compensation or $72,000 | Employer contribution cap for 2026 SEP IRAs |
| Compensation cap for calculations | $360,000 | Only compensation up to this amount is counted for the limit |
| Maximum contribution at compensation cap | $72,000 | Even though 25% of $360,000 is $90,000, the IRS cap applies |
| Self-employed contribution basis | Net earnings after deducting one-half of self-employment tax | Uses adjusted self-employment income, not gross business income |
| Effective maximum rate for self-employed individuals | Approximately 20% of net earnings | Approximate deduction rate after self-employed plan calculations |
| Catch-up contributions (age 50+) | Not allowed | SEP plans do not permit elective salary deferrals or catch-up contributions |

Eligibility Requirements
A SEP plan must include all eligible employees.
The IRS sets minimum eligibility standards that employers may use, unless they choose less restrictive rules.
- Age and Service: Be age 21 or older and have worked for the employer in at least 3 of the last 5 years.
- Minimum Compensation: Have earned at least a threshold amount during the year from that employer.
Certain workers, such as union-covered employees or nonresident aliens without U.S. wages, may be excluded.
Is SEP IRA Taxed?
SEP IRA contributions are tax-advantaged for both the employer and the employee.
| Rule | Tax treatment |
|---|---|
| Contributions | Tax-deductible (pre-tax) |
| Growth | Tax-deferred |
| Withdrawals | Taxed as ordinary income |
| Early withdrawal (<59½) | +10% penalty + income tax |
For the employer, contributions are deductible as a business expense.
For the employee, contributions are not taxed when made and do not show up as current wages.
So, your money grows tax-deferred until it is withdrawn later.
SEP-IRA FAQs
No. Only the employer, or a self-employed individual acting as the employer, can contribute. Employees may still contribute separately to an IRA or Roth IRA within annual limits.
A SEP must be adopted by the employer’s tax filing deadline, generally April 15 or October 15 with extension. Contributions can be made up to that deadline and still count for the prior tax year.
No. Employer SEP contributions are not included in taxable wages or W-2 boxes. Employers simply indicate retirement plan coverage on the W-2.
Withdrawals are taxed as ordinary income. Early withdrawals before age 59½ may incur a 10% penalty unless an exception applies. Required minimum distributions begin at age 73.
Yes. SEP-IRAs can be rolled into other traditional IRAs or qualified plans tax-free, or converted to a Roth IRA with taxes due on the converted amount.
Excess contributions must be corrected or withdrawn. Otherwise, they may become taxable and non-deductible. IRS correction procedures may apply.
No direct restriction. Individuals may still contribute to IRAs or participate in 401(k)s. However, SEP participation may affect IRA deductibility based on income and tax filing status.
