A SEP IRA lets self-employed individuals and small business owners contribute up to 25% of compensation per employee, with a maximum of $69,000 for 2024. A SEP IRA, or Simplified Employee Pension Individual Retirement Account, is a tax-deferred retirement plan designed for self-employed individuals and small business owners who want higher contribution limits than a standard IRA allows.

What Is a SEP IRA?

A SEP IRA, or Simplified Employee Pension Individual Retirement Account, is a tax-deferred retirement plan designed for self-employed individuals and small business owners who want higher contribution limits than a standard IRA allows.

The “simplified” in the name reflects the plan’s actual design philosophy. Unlike a 401(k), a SEP IRA requires no complex plan documents, no nondiscrimination testing, and no annual Form 5500 filing for most plan sponsors. You open the account, contribute when your finances allow, and deduct those contributions from your business income. The IRS created the SEP IRA specifically to give sole proprietors, freelancers, and small business owners access to meaningful retirement savings tools without the administrative overhead of larger corporate plans.

For retirement savers who work for themselves, the SEP IRA closes a significant gap. A standard traditional IRA caps contributions at $7,000 per year (or $8,000 if you are 50 or older) in 2024. A SEP IRA can accept up to $69,000 in the same year, depending on income. That difference, compounded over a career, shapes the retirement outcome in a fundamental way.

How a SEP IRA Works

A SEP IRA functions similarly to a traditional IRA in most respects. Contributions are tax-deductible, the account grows tax-deferred, and withdrawals in retirement are taxed as ordinary income. The critical structural difference is that only the employer contributes. If you are self-employed, you are both the employer and the employee, so you make contributions on your own behalf.

The contribution limit is the smaller of 25% of the employee’s net compensation or $69,000 (2024 figure, indexed to inflation annually). For a self-employed individual, “compensation” is calculated as net self-employment income after deducting half of self-employment tax and the SEP contribution itself. This circular calculation requires a specific IRS worksheet, found in Publication 560, to get right.

If a business has employees, the rules tighten. The employer must contribute the same percentage of compensation for all eligible employees as they contribute for themselves. You cannot selectively contribute for some employees and not others. Eligible employees are generally those who are at least 21 years old, have worked for the business in at least three of the last five years, and received at least $750 in compensation during the year. These thresholds can be relaxed but not tightened.

Accounts are immediately 100% vested. The moment a contribution lands in an employee’s SEP IRA, that money belongs to the employee entirely.

Regulations That Govern a SEP IRA

The IRS treats each participant’s SEP IRA as an individual traditional IRA for distribution purposes. That means the same rules apply: withdrawals before age 59½ trigger a 10% early withdrawal penalty plus ordinary income tax, with some exceptions. Required minimum distributions begin at age 73 under the SECURE 2.0 Act.

Contributions must be made by the employer’s tax filing deadline, including extensions. A sole proprietor who files on extension until October 15 can make SEP IRA contributions up until that date for the prior tax year. That flexibility is one of the plan’s most practical advantages.

The IRS does not require a formal written plan document for a SEP IRA, but it does require that you use a written agreement, typically Form 5305-SEP or a prototype plan from a financial institution. Form 5305-SEP is not filed with the IRS. It stays on file with the employer. Many financial institutions that offer SEP IRAs handle this paperwork as part of the account-opening process.

A SEP IRA can hold the same types of investments as a traditional IRA: stocks, bonds, mutual funds, ETFs. If you open a self-directed SEP IRA through a qualified custodian, the account can also hold IRS-approved physical precious metals, including gold with a minimum fineness of .995 and silver with a minimum fineness of .999.

SEP IRA in Practice

Consider a freelance graphic designer who earns $120,000 in net self-employment income in 2024. After deducting half of self-employment tax (approximately $8,478), her adjusted net earnings for SEP calculation purposes are roughly $111,522. Twenty-five percent of that figure is approximately $27,880, which is the maximum she can contribute to her SEP IRA for that year.

She makes the contribution in March of the following year, before her tax filing deadline. That $27,880 is fully deductible from her gross income, reducing her taxable income and her federal income tax bill for the prior year. The money goes into her SEP IRA and grows tax-deferred until she begins taking distributions in retirement.

If she hires an assistant later and pays that employee $50,000, she must contribute the same percentage for the assistant that she contributes for herself. If she contributes 25% for herself, she contributes 25% of $50,000, or $12,500, to the assistant’s SEP IRA.

SEP IRA vs. SIMPLE IRA

A SIMPLE IRA, or Savings Incentive Match Plan for Employees, is another retirement plan designed for small businesses, but the mechanics differ in important ways.

The most significant difference is who contributes. In a SIMPLE IRA, both the employer and the employee make contributions. Employees can defer up to $16,000 of their salary in 2024 (plus a $3,500 catch-up for those 50 and older). Employers are required to match contributions up to 3% of compensation or make a flat 2% non-elective contribution for all eligible employees. In a SEP IRA, only the employer contributes, and there is no employee salary deferral.

For a high-earning sole proprietor with no employees, the SEP IRA almost always wins on contribution limits. A freelancer earning $200,000 can contribute up to $50,000 to a SEP IRA, far more than the SIMPLE IRA’s employee contribution cap. For a small business owner who wants to offer employees a way to save their own money alongside a modest employer contribution, the SIMPLE IRA fits better. The right choice depends on your income level, your workforce, and how much you want employees to participate in their own savings.

Common Mistakes and Red Flags

Ignoring the compensation calculation. Self-employed savers frequently overestimate their contribution limit by using gross revenue instead of net self-employment income after required adjustments. Use the IRS worksheet in Publication 560 or work with a tax professional.

Missing the contribution deadline. Contributions must be deposited by the tax filing deadline including extensions. Missing the deadline means you lose the deduction for that year.

Skipping eligible employees. If you have employees who meet the age, service, and compensation thresholds, you must cover them at the same contribution percentage you use for yourself. Failing to do so violates the plan’s terms.

Treating SEP contributions as optional indefinitely. If you have employees, skipping contributions for yourself does not eliminate your obligation to contribute for eligible employees in years when you do contribute for yourself.

Confusing SEP IRA accounts with the plan itself. Each participant holds their own individual SEP IRA. The business establishes the plan, but the accounts belong to the individuals. Understand the distinction before making investment decisions.

Why a SEP IRA Matters for Your Retirement Plan

For self-employed individuals, retirement savings require deliberate action. There is no payroll deduction, no employer match, and no default enrollment. The SEP IRA gives you a tool with contribution limits that rival corporate retirement plans, combined with simplicity that makes it practical to actually use.

The deduction is immediate and meaningful. A $30,000 SEP IRA contribution at a 24% tax bracket saves $7,200 in federal taxes in the current year while building long-term retirement capital. Over a 20-year career, that combination of tax savings and compound growth represents a substantial difference in financial security.

For savers who want to diversify retirement assets beyond paper markets, a self-directed SEP IRA opens access to IRS-approved physical gold and silver. The same contribution limits apply. The same tax treatment applies. The assets are simply held at an approved depository rather than a brokerage. If diversifying into tangible assets is part of your retirement thinking, the SEP IRA does not limit that option.

The Bottom Line

A SEP IRA is one of the most powerful retirement savings tools available to the self-employed. The contribution limits are high, the setup is straightforward, and the tax advantages are immediate. If you work for yourself and have not yet explored what a SEP IRA can do for your retirement outlook, the gap between what you are saving now and what you could be saving deserves a close look.

Frequently Asked Questions

Can a sole proprietor with no employees open a SEP IRA?

Yes. A sole proprietor with no employees is the most common SEP IRA participant. You act as both employer and employee, contribute on your own behalf, and deduct the contribution from your business income. There is no minimum number of employees required to establish the plan.

Is a SEP IRA the same as a traditional IRA?

A SEP IRA uses the traditional IRA framework for distributions and investments, but the contribution limits are much higher and contributions come entirely from the employer. The tax treatment at distribution is identical: withdrawals are taxed as ordinary income, and early withdrawals before age 59½ are subject to a 10% penalty.

Can I roll a SEP IRA into a different type of retirement account?

Yes. SEP IRAs can be rolled over into traditional IRAs, other SEP IRAs, SIMPLE IRAs (after a two-year holding period), and eligible employer-sponsored plans like 401(k)s. A rollover to a Roth IRA is also allowed but triggers income tax on the amount converted.

What happens if I contribute more than the SEP IRA limit?

Contributions above the annual limit are considered excess contributions and are subject to a 6% excise tax for each year the excess remains in the account. Correcting the excess before the tax filing deadline, including extensions, avoids the penalty.

Can I hold gold or silver in a SEP IRA?

Yes, through a self-directed SEP IRA. The account must be held at an IRS-approved custodian, and any physical metals must meet IRS purity standards and be stored at an approved depository. Gold must be at least .995 fine, and silver must be at least .999 fine to qualify.
