A SEP IRA, or Simplified Employee Pension IRA, is a retirement plan for self-employed people and small-business owners that allows employer-only contributions into traditional IRAs set up for eligible employees. It stands out because it offers much higher contribution limits than a traditional or Roth IRA, while keeping setup and administration relatively simple, according to the IRS.

A SEP IRA can be a strong option if you want flexible contributions, tax deductions and a straightforward retirement plan for a small business. But it can get expensive if you have employees, because eligible workers generally must receive the same contribution percentage as the owner.

What Is a SEP IRA?

A SEP IRA is a retirement plan that lets an employer contribute to traditional IRAs for employees. The IRS says a business of any size, including a self-employed person, can establish a SEP.

In plain terms, it’s a simpler employer-funded retirement plan that works especially well for:

• Self-employed individuals
• Freelancers and contractors
• Sole proprietors
• Partnerships
• LLCs
• Corporations with a small number of employees

Key Insight: A SEP IRA is funded by the employer only. Employees do not make salary-deferral contributions the way they can in a 401(k) or SIMPLE IRA.

How Does a SEP IRA Work?

A SEP IRA works by allowing the employer to contribute to a traditional IRA established for each eligible employee. Those contributions are generally tax-deductible to the business, and the money grows tax-deferred until it’s withdrawn in retirement.

Here’s the basic structure:

• The employer sets up the SEP plan
• A SEP IRA is opened for each eligible employee
• The employer decides whether to contribute each year
• Contributions vest immediately
• Withdrawals are taxed as ordinary income in retirement

One of the biggest advantages is flexibility. The IRS says employers can decide each year whether to contribute, which can help if business income fluctuates.

Who Can Open a SEP IRA?

A SEP IRA can be opened by a business of any size, including someone self-employed. That includes sole proprietors, partnerships, LLCs and corporations.

Who Can Use One?

• Self-employed individuals
• Freelancers and gig workers
• Independent contractors
• Small-business owners
• Partnerships
• Corporations
• LLCs

Who Is Eligible To Participate in a SEP IRA?

The IRS sets a standard baseline for employee eligibility. For 2026, an eligible employee generally must:

• be at least 21
• have worked for the employer in at least 3 of the last 5 years
• have received at least $800 in compensation from the employer in 2026

An employer can choose less restrictive rules, but not more restrictive ones.

Tip: If you have employees, check eligibility carefully before choosing a SEP IRA. A plan that feels simple for a solo business owner can become more expensive once staff qualify.

What Are the SEP IRA Contribution Limits for 2026?

For 2026, SEP IRA contributions are limited to the lesser of:

• 25% of an employee’s compensation
• $72,000

The IRS also raised the compensation cap used in retirement-plan calculations to $360,000 for 2026. That makes SEP IRAs much more generous than traditional and Roth IRAs, which have much lower annual contribution limits.

Example

If an eligible employee earns $150,000 and the business contributes 25%, the contribution would be $37,500 for that year.

For self-employed people, though, the calculation isn’t always as simple as taking 25% of gross income. IRS formulas for self-employed SEP contributions adjust for self-employment tax and other factors, so many business owners use tax software or a CPA to calculate the exact maximum.

What Are the Main IRS Rules for SEP IRAs?

The key SEP IRA rules are fairly straightforward.

Main SEP IRA rules

• Employer-only contributions: Employees don’t contribute directly to the SEP IRA
• Immediate vesting: Contributions belong to the employee right away
• Equal contribution percentage: If you contribute for yourself, you generally must contribute the same percentage of compensation for eligible employees
• Flexible annual funding: You can choose whether and how much to contribute each year, subject to IRS limits
• Traditional IRA tax treatment: Withdrawals are generally taxed as ordinary income, and early withdrawals may face a 10% penalty unless an exception applies

What Are the Tax Benefits of a SEP IRA?

A SEP IRA can offer meaningful tax advantages.

Main Tax Benefits

• Employer contributions are generally tax-deductible to the business
• Investments grow tax-deferred until withdrawal
• Contributions can help reduce the current taxable business income

The tradeoff is that withdrawals in retirement are generally taxed as ordinary income, just like traditional IRA distributions.

SEP IRA vs. Traditional IRA vs. Roth IRA: What’s the Difference?

A SEP IRA is very different from a traditional or Roth IRA when it comes to contribution size and who can fund it.

Feature	SEP IRA	Traditional IRA	Roth IRA
Best for	Self-employed people and small-business owners	People with earned income	People with earned income and qualifying income level
Who contributes	Employer only	Individual	Individual
2026 contribution potential	Up to $72,000, subject to limits	Much lower annual IRA limit	Much lower annual IRA limit
Tax treatment now	Employer deduction	Often deductible	After-tax contributions
Tax treatment later	Taxed on withdrawal	Taxed on withdrawal	Qualified withdrawals tax-free
RMDs	Yes	Yes	No lifetime RMDs for original owner

The biggest reason people choose a SEP IRA is the contribution room. The biggest reason they may skip it is the employee cost if the business has staff.

What Are the Pros and Cons of a SEP IRA?

Pros

• High contribution limits: up to $72,000 for 2026, subject to IRS rules
• Easy setup: The IRS allows employers to establish a SEP with a formal written agreement, often using Form 5305-SEP
• Flexible contributions: You can decide year by year whether to contribute
• Tax-deductible contributions: Helpful for reducing taxable business income
• Can be paired with other IRA ownership: You can still also have a traditional or Roth IRA, subject to IRA rules

Cons

• Employer-only contributions: Employees can’t contribute directly to the SEP IRA
• Same contribution percentage for eligible employees: Can become expensive if you have staff
• No catch-up contributions: SEP IRAs don’t have age-50 catch-up contributions like some other retirement plans
• RMDs apply: SEP IRAs follow IRA RMD rules starting at age 73
• Early withdrawals can trigger penalties: Generally, 10% before age 59½ unless an exception applies

How Do You Open a SEP IRA?

Opening a SEP IRA is usually pretty straightforward.

Steps to open a SEP IRA

1. Choose a financial institution that offers SEP IRAs.
2. Execute a formal written agreement, often using IRS Form 5305-SEP if it fits your business structure.
3. Set up a SEP IRA for each eligible employee.
4. Fund the account based on your chosen contribution amount and IRS limits.
5. Select your investments.

The IRS says you can generally set up a SEP as late as the due date of the business’s tax return, including extensions, for the year you want to make contributions.

When Does a SEP IRA Make Sense?

A SEP IRA often makes the most sense if you:

• Are self-employed
• Run a business with few or no employees
• Want high contribution limits
• Want flexibility to contribute more in good years and less in leaner years
• Want a simpler plan than a solo 401(k) or more complex employer plan

It can be especially attractive for high-income self-employed people who want a large tax deduction and fast retirement-plan funding.

When Might a SEP IRA Not Be the Best Choice?

A SEP IRA may be less attractive if:

• You have several employees who qualify for contributions
• You want employees to contribute from their own pay
• You want catch-up contributions after age 50
• You want a plan better suited to predictable employee deferrals

In those cases, comparing a SIMPLE IRA or solo 401(k) may make sense.

Final Take to GO

A SEP IRA is a retirement plan built for self-employed people and small-business owners who want high contribution limits, flexible employer funding and tax-deductible contributions. For 2026, the contribution limit is the lesser of 25% of compensation or $72,000, which makes it one of the most powerful retirement tools available to eligible business owners.

It’s often a great fit for solo business owners and high earners. But if you have employees, the equal-percentage contribution rule can make a SEP IRA much more expensive than it first appears.
