What Is a Keogh Plan? Self-Employed Retirement Explained

If you freelanced in the 1990s or sat through a CPA dinner in the early 2000s, someone almost certainly mentioned a Keogh plan. The word still shows up in old plan documents, bank marketing, and dinner-table advice from relatives who saved as sole proprietors. What it usually means today is simpler than the nickname suggests. A Keogh (also called an H.R. 10 plan) was the classic label for a tax-qualified retirement plan set up by a self-employed person. After federal law leveled the field between corporate and unincorporated sponsors, the IRS mostly folds that idea into ordinary qualified plans. The nickname stuck. The product aisle moved on to SEP IRAs, solo 401(k)s, and, for some high earners, defined benefit designs.

This guide explains what people still mean by Keogh, how contribution mechanics work at a high level, who those plans were built for, and how the modern menu compares. Figures for 2026 come from IRS announcements and Publication 560 style materials where noted. Nothing here is personalized tax, legal, or investment advice. Plan documents and a professional who sees your return still control.

What a Keogh Plan Was (and Still Is, Under Another Name)

In plain English, a Keogh plan is a qualified retirement plan for a business that is not a corporation in the old sense of the word, or more accurately, for a self-employed individual and any employees covered under the same plan. Sole proprietors, partners, and many LLC owners taxed as self-employed used Keogh language for decades. The plan could be a profit-sharing plan, a money purchase pension plan, a defined benefit plan, or a combination. Contributions were deductible within IRS limits. Growth inside the plan was tax-deferred. Distributions in retirement were generally taxed as ordinary income.

IRS Publication 560 still notes that qualified plans are also called H.R. 10 plans or Keogh plans when they cover self-employed individuals. So if a brochure or an older Form 5500 package says Keogh, it is usually pointing at a qualified plan for a self-employed sponsor, not a mysterious fourth account type that sits beside IRAs and 401(k)s.

Two design families mattered historically:

• Defined contribution Keoghs (profit-sharing and money purchase). Each participant has an account. The benefit equals whatever sits in the account after contributions and investment results.
• Defined benefit Keoghs. The plan promises a formula benefit at retirement. Required funding can be large when the owner is older and income is high, which is why some professionals still use defined benefit or cash balance designs under modern qualified-plan rules.

Money purchase plans once forced a fixed contribution percentage every year. Profit-sharing plans allowed more discretion. Over time, many owners preferred the flexibility of profit sharing, SEP IRAs, and later the solo 401(k), which combined employee-style deferrals with employer-style profit sharing in one package.

A Short History: Why the Nickname Exists

Self-employed workers once lacked the same tax-favored retirement tools that corporations offered employees. Congress answered with the Self-Employed Individuals Tax Retirement Act of 1962, often tied to bill H.R. 10 and to Representative Eugene Keogh. The popular name followed the sponsor. For decades, contribution limits and some administrative rules for self-employed plans lagged or differed from corporate plans, which kept the Keogh label useful as a distinct category.

The Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA) is the turning point most educators cite. It largely aligned contribution opportunities so that unincorporated owners and corporate plans lived under the same broad qualified-plan ceilings. After that, marketers and the IRS leaned harder on ordinary labels: profit-sharing plan, money purchase plan, defined benefit plan, 401(k). Keogh remained a cultural shorthand, especially among older advisors and savers who opened plans before the rewrite.

That history explains a common confusion. People ask whether Keogh plans were repealed. The underlying idea was not deleted. The special brand name stopped being necessary once the Code stopped treating self-employed qualified plans as a permanently second-class cousin.

Who Keogh Plans Were For

Classic Keogh eligibility centered on net earnings from self-employment. Think sole proprietors filing Schedule C, partners with self-employment income, and many LLC members taxed that way. If the business hired employees, the plan generally had to cover them under nondiscrimination and eligibility rules. That last point still matters under modern qualified plans. A solo shop with no employees other than a spouse can often run a one-participant design with lighter paperwork. A shop with staff usually cannot quietly fund only the owner.

People who incorporated as an S corporation or C corporation typically set up corporate qualified plans rather than calling the arrangement a Keogh, even when the economic goal was identical. The nickname followed the self-employed tax posture more than the daily work of consulting, dentistry, farming, or freelance design.

Common profiles that once lived in Keogh marketing:

• Professionals with uneven but strong Schedule C income (attorneys, physicians in private practice, accountants, consultants).
• Partners who wanted a deductible contribution larger than a plain IRA.
• Owners willing to accept plan documents, possible Form 5500 filings, and trustee or custodian paperwork in exchange for higher ceilings.

Those same people today often hear SEP IRA or solo 401(k) first. The need did not vanish. The product names on the shelf changed.

Contribution Mechanics at a High Level

You do not need actuarial training to understand the skeleton. For defined contribution designs that people called Keoghs, the employer (which might be you) contributes within plan terms and IRS limits. For a self-employed person, compensation is not a W-2 in the usual sense. It is earned income: net earnings from self-employment after certain adjustments, including a reduction related to the deductible half of self-employment tax and the retirement contribution itself. IRS materials walk through that circular math because the contribution lowers the income base used to size the contribution.

Profit-sharing style contributions are often discussed as up to 25 percent of eligible compensation for employees, with a parallel but carefully computed percentage for the owner. Money purchase designs historically locked in a stated percentage. Defined benefit designs reverse the logic: start from a promised benefit, then compute the contribution needed to fund it.

For 2026, several dollar ceilings matter across the modern successors to Keogh designs:

• IRA contribution limit: $7,500, plus a $1,100 catch-up for eligible savers age 50 and older.
• Employee elective deferral limit for 401(k), 403(b), most governmental 457 plans, and the Thrift Savings Plan: $24,500. Many plans allow an $8,000 catch-up at age 50 or older. Some plans allow an $11,250 catch-up for people who turn 60, 61, 62, or 63 during the year.
• SEP maximum contribution: the lesser of 25 percent of compensation or $72,000.
• Defined contribution annual additions limit under section 415(c): the lesser of 100 percent of compensation or $72,000 (catch-up amounts can raise the combined picture further when you qualify).
• Annual compensation limit taken into account for many calculations: $360,000.

Those numbers are shared across plan types. A legacy Keogh profit-sharing document and a brand-new solo 401(k) both live under the same sky of IRS ceilings, even if the nicknames on the cover differ.

How Keogh Talk Maps to Modern Options

When someone says they want a Keogh in 2026, translate the request into a concrete product.

SEP IRA

A Simplified Employee Pension lets an employer contribute to traditional IRAs set up for eligible employees, including the owner. Setup is relatively light. There are no employee elective deferrals in a regular SEP. For 2026, employer contributions cannot exceed the lesser of 25 percent of compensation or $72,000. If you have employees, you generally must contribute for them under the plan's formula when you contribute for yourself. Many sole props with no staff like SEPs for simplicity. Owners who want to defer a large slice of personal pay as an employee often outgrow a SEP and look at a solo 401(k).

Solo 401(k) (one-participant 401(k))

This is the workhorse for many owner-only businesses. You wear two hats. As employee, you can elect deferrals up to the $24,500 limit for 2026 (plus catch-up if eligible). As employer, you can add a nonelective or profit-sharing contribution within deductible limits, commonly discussed around 25 percent of eligible compensation, subject to the overall $72,000 annual additions ceiling before catch-up. The IRS maintains a dedicated page on one-participant 401(k) plans. Once the plan covers employees other than a spouse, it stops being a simple one-participant design and full 401(k) rules apply.

Profit-sharing and money purchase qualified plans

These are the direct descendants of defined contribution Keoghs. Profit sharing remains popular because contributions can vary by year. Money purchase plans are less common for new setups because the fixed funding commitment feels rigid next to profit sharing or a solo 401(k). If an older Keogh document is still open, a tax professional can explain whether to keep, amend, or merge it into a cleaner design.

Defined benefit and cash balance plans

High-income owners in their 50s and early 60s sometimes still want the large deductible contributions that a defined benefit formula can support. Those plans are qualified plans, not IRAs. Actuarial work, funding rules, and PBGC considerations (when applicable) raise cost and complexity. The educational point for Keogh history is simple: the old defined benefit Keogh lane never fully disappeared. It rebranded as modern defined benefit or cash balance planning for the self-employed and small firms.

SIMPLE IRA

For smaller employers who want employee deferrals with lighter administration than a full 401(k), a SIMPLE IRA can fit. Employee deferral limits are lower than a regular 401(k). For 2026 the SIMPLE elective deferral limit is $17,000 under IRS COLA tables, with its own catch-up rules. It is usually not the first translation of classic Keogh talk, but it sits on the same self-employed and small-business shelf.

Keogh vs SEP vs Solo 401(k): A Practical Comparison

Use this as an education map, not a ranking for every household.

• Ceiling height. A SEP tops out at the employer contribution limit ($72,000 / 25 percent framework for 2026). A solo 401(k) can often reach a similar overall additions ceiling while letting a large piece arrive as an employee deferral, which helps when earned income is modest relative to the deferral limit. A plain IRA at $7,500 is far smaller.
• Employee deferrals. Regular SEPs do not allow them. Solo 401(k)s do. Classic profit-sharing Keoghs without a 401(k) feature also lacked paycheck-style elective deferrals.
• Roth options. Many solo 401(k)s offer designated Roth deferrals. SEP contributions go to traditional SEP-IRAs (Roth conversion strategies exist but are a separate conversation). Confirm plan terms rather than assuming.
• Loans. Some qualified plans, including many solo 401(k)s, permit participant loans if the document allows them. IRAs (including SEP-IRAs) generally do not. Older Keogh lore sometimes claimed owner loans were banned; EGTRRA-era changes and modern plan design largely put owner-employees on the same loan footing as other participants when the document permits loans.
• Paperwork. SEPs are usually the lightest. Solo 401(k)s and other qualified plans can require a written plan, timely adoption, and Form 5500-EZ once assets or other thresholds are met. Legacy Keogh plans carried a reputation for heavier administration than IRAs, which is one reason SEPs and prototype solo 401(k)s won shelf space.
• Employees. The moment you hire staff who must be covered, costs and testing jump. A design that felt perfect as a solo Keogh or solo 401(k) can become expensive overnight.

Arithmetically, a quick teaching example helps. Suppose a self-employed consultant has enough earned income to support a full employee deferral and a solid employer contribution in a solo 401(k). Electing $24,500 as an employee for 2026, then adding an employer profit-sharing contribution sized under the 25 percent style rules, can approach the $72,000 overall additions area before catch-up when income is high enough. The same person using only a SEP would rely entirely on the employer contribution formula and could not use the elective deferral lane. Someone limited to a traditional or Roth IRA would face the $7,500 ceiling (plus catch-up if eligible). Exact owner math still needs the earned-income worksheet. The comparison is about lanes, not a promise that every Schedule C reaches the ceiling.

Taxes, Deadlines, and Distributions in Plain English

Deductible contributions to a Keogh-style qualified plan or a SEP generally reduce taxable income for the year they apply, subject to the usual limits. Investment growth inside the plan is typically tax-deferred. Withdrawals are usually taxed as ordinary income. Taking money before age 59 and a half often triggers an additional 10 percent tax unless an exception applies. Required minimum distributions eventually apply under current law, with timing that depends on birth year and work status.

Setup and funding deadlines differ by plan type and matter a lot. As a high-level pattern many educators teach: a qualified plan generally must be adopted by the end of the tax year for which you want a deduction, while funding can often wait until the tax filing deadline including extensions. SEP establishment and funding windows are often more forgiving and can extend to the filing deadline including extensions. Solo 401(k) adoption timing has been clarified in recent years so that, in many cases, the plan can be established by the filing deadline including extensions for the year of the deduction, but elective deferrals still have payroll and election timing rules that bite if you wait too long. Always confirm the current rule for the exact product you use. Missing a deadline is one of the most expensive self-employed mistakes in this category.

Self-employed contributions are typically deducted on Schedule 1 of Form 1040 on the line for self-employed SEP, SIMPLE, and qualified plans, not as a Schedule C expense that reduces net profit before self-employment tax in the same way wages would. That placement surprises new freelancers. Publication 560 and the IRS self-employed contribution pages explain the computation.

Cash Staging Before You Fund the Plan

Self-employed retirement contributions feel abstract until the estimated tax voucher and the plan funding date land in the same month. A practical habit many owners use is to skim a percentage of every client payment into a holding account, then move a planned amount into the SEP or solo 401(k) on a schedule. Parking that staging cash in a high-yield savings account keeps it liquid and separate from checking, which reduces the odds that a slow receivables month raids the retirement earmark.

Near-term emergency cash still belongs outside retirement accounts. Raiding a Keogh-era qualified plan or a SEP for a transmission repair can create taxes, possible penalties, and lost compounding. Build a liquid cushion first, or in parallel, while you raise plan contributions as cash flow stabilizes.

What Steady Self-Employed Contributions Can Grow Into

Compound growth does not care whether the brochure said Keogh, SEP, or solo 401(k). It cares about dollars, time, fees, and return. The illustrations below are educational assumptions: monthly equivalents, a 7 percent average annual return, and no Social Security or pension layered on top. Real markets are lumpy. Fees differ. These are teaching examples, not forecasts.

Contribute the equivalent of $500 per month for 25 years at 7 percent average annual return, compounded monthly, and the future value is roughly $405,000. At $1,000 per month for the same horizon, the illustration is roughly $810,000. At $1,500 per month, roughly $1.22 million. Stretch any of those habits to 30 years and time does as much work as the contribution rate.

Use the interactive slider to model your current age, target retirement age, starting balance, monthly contribution, and assumed return. Change one input at a time. Notice how sensitive the ending balance is to years invested and to a modest bump in the monthly amount. That sensitivity is why opening any workable plan this year usually beats waiting two more seasons for a theoretically perfect document.

Common Confusions Worth Clearing

1. "Keogh plans were banned." No. The nickname faded after contribution rules were aligned. Qualified plans for the self-employed remain.
2. "A Keogh is a type of IRA." Not quite. Classic Keoghs were qualified plans. SEPs use IRA accounts as the funding vehicle. Solo 401(k)s are qualified plans that can look IRA-like at a brokerage but follow 401(k) rules.
3. "I can ignore employees." Coverage and nondiscrimination rules still apply when you have staff. Solo designs exist for a reason.
4. "Maxing is mandatory." Limits are ceilings, not homework. Many healthy careers fund far below the $72,000 area while still building a serious nest egg.
5. "The plan replaces an emergency fund." It does not. Keep short-horizon cash liquid.
6. "Any online calculator knows my earned income." Owner contribution math is circular. A tax professional or carefully followed IRS worksheet beats a generic percentage applied to gross receipts.

A Calm Decision Path for Self-Employed Readers

If you are choosing a lane in 2026, a neighborly sequence looks like this:

1. Estimate stable earned income after business expenses, not a single lucky month.
2. Decide whether you have (or will soon have) employees other than a spouse.
3. If you want simplicity and employer-only contributions, study a SEP IRA.
4. If you want employee deferrals plus employer profit sharing, and you are owner-only, study a solo 401(k).
5. If income is very high and you are older, ask a specialist whether a defined benefit or cash balance design belongs in the conversation.
6. Adopt the plan on time, fund it on time, invest the cash (do not leave it in a default sweep forever), and keep beneficiaries updated.

That path honors what Keogh plans were trying to do in 1962: give self-employed people a serious, deductible way to save for later life. The vocabulary refreshed. The need did not.

The Bottom Line

A Keogh plan is the historic name for a qualified retirement plan covering self-employed individuals, also called an H.R. 10 plan in IRS materials. Defined contribution and defined benefit versions both existed. After EGTRRA-era alignment, everyday shopping usually happens under labels like SEP IRA, solo 401(k), profit-sharing plan, or defined benefit plan, all living under shared 2026 ceilings such as the $7,500 IRA limit, the $24,500 elective deferral limit, and the $72,000 SEP and defined contribution additions framework. If an old document still says Keogh, read it as a qualified plan and review it with a professional. If you are starting fresh, pick the modern product that matches your income pattern, hiring plans, and paperwork tolerance, stage cash so funding day is calm, and let time and compounding do the quiet work.
