Definition and Overview
A Keogh plan is a tax-advantaged retirement savings plan available to self-employed individuals and unincorporated businesses, including sole proprietors and partners in partnerships, that allows them to make tax-deductible contributions toward their retirement savings in a manner analogous to the employer-sponsored retirement plans available to employees of corporations. Named after Representative Eugene Keogh of New York, whose legislative efforts led to the passage of the Self-Employed Individuals Tax Retirement Act of 1962 that created this retirement savings vehicle, the Keogh plan was for many decades the primary mechanism through which self-employed Americans could accumulate tax-advantaged retirement savings comparable to the pension and profit-sharing plans available to corporate employees.
The Keogh plan occupies an important historical position in the development of the US retirement savings framework, representing the first significant legislative recognition that self-employed individuals deserved access to tax-advantaged retirement savings vehicles equivalent to those available through employer-sponsored plans. Prior to the creation of the Keogh plan, self-employed individuals had no access to employer-sponsored retirement savings vehicles and could not make tax-deductible contributions toward their retirement savings, placing them at a significant disadvantage relative to corporate employees who could participate in pension and profit-sharing plans funded with pre-tax dollars.
While the Keogh plan remains a valid and available retirement savings vehicle for self-employed individuals, its practical significance has diminished considerably since the 1980s as simpler and more flexible alternatives including the Simplified Employee Pension IRA and the Solo 401(k) plan have become available and have in most circumstances superseded the Keogh plan as the preferred retirement savings vehicles for self-employed individuals. Understanding the Keogh plan is important for investment professionals both for historical context and because existing Keogh plans remain in force for many clients who established them before the alternatives became available.
Types of Keogh Plans
The Keogh plan framework encompasses two primary structures that differ in how contributions are calculated and how they relate to the plan's benefit promises to participants.
A defined contribution Keogh plan specifies the contribution formula rather than the ultimate retirement benefit, with the participant's retirement income depending on the accumulated contributions and their investment returns over the plan's life. Defined contribution Keogh plans come in two variants that differ in their contribution flexibility and calculation methodology. A profit-sharing Keogh plan allows the self-employed individual to vary their annual contribution from zero up to the maximum allowable amount based on their business profitability and cash flow needs, providing flexibility that is particularly valuable for businesses with variable annual income. A money purchase Keogh plan requires a fixed percentage contribution each year regardless of business profitability, providing less flexibility but potentially allowing higher contributions in some circumstances.
A defined benefit Keogh plan specifies the retirement benefit the participant will receive, with annual contributions calculated by an actuary based on the benefit promise, the participant's age, and the investment returns required to fund the promised benefit. Defined benefit Keogh plans can allow substantially larger tax-deductible contributions than defined contribution plans for older participants who have limited time to accumulate retirement savings, because the actuarial calculation determines the contribution needed to fund a specific benefit stream that can be set at a high level for highly compensated older participants.
Contribution Limits and Tax Treatment
The contribution limits applicable to Keogh plans are determined by the same general framework that governs other qualified retirement plans under the Internal Revenue Code, with the specific limits varying by plan type and being subject to annual inflation adjustments.
For defined contribution Keogh plans, the maximum annual contribution is limited to the lesser of twenty-five percent of the participant's net self-employment income or the annual defined contribution limit established by the IRS, which was sixty-six thousand dollars for 2023 and is subject to annual cost-of-living adjustments. The net self-employment income for this purpose is calculated after the deduction for one-half of the self-employment tax, reflecting the fact that self-employed individuals bear both the employee and employer portions of payroll taxes.
Contributions to a Keogh plan are deductible from federal income taxes in the year they are made, reducing the participant's current-year tax liability and allowing the contributed funds to grow tax-deferred until withdrawn. Withdrawals from a Keogh plan in retirement are taxed as ordinary income in the year received, following the same basic framework applicable to traditional IRAs and other pre-tax retirement accounts. Withdrawals taken before age fifty-nine and a half are subject to a ten percent early withdrawal penalty in addition to ordinary income tax, with certain exceptions for disability, substantially equal periodic payments, and other specified circumstances.
Keogh Plans and ERISA
As qualified retirement plans, Keogh plans are subject to the Employee Retirement Income Security Act of 1974, the comprehensive federal legislation governing private sector retirement plans that is discussed in the Fiduciary article in Section F. ERISA imposes substantial administrative and compliance obligations on Keogh plans, including annual Form 5500 reporting requirements for plans with more than one participant, plan document requirements, vesting standards if the plan covers employees in addition to the self-employed owner, non-discrimination requirements ensuring the plan does not disproportionately benefit highly compensated participants, and various other regulatory standards designed to protect plan participants.
The ERISA compliance burden is one of the primary reasons that self-employed individuals have increasingly preferred the SEP-IRA and Solo 401(k) alternatives to the traditional Keogh plan. Both alternatives offer comparable or superior contribution limits with substantially lower administrative complexity and cost, making the Keogh plan's more burdensome regulatory requirements difficult to justify for most self-employed individuals who lack the dedicated administrative resources to manage a full ERISA-compliant qualified plan.
Comparison with Alternative Self-Employment Retirement Plans
The evolution of the retirement savings landscape since the Keogh plan's creation has produced several alternative vehicles that offer competitive advantages for most self-employed individuals in most circumstances.
The Simplified Employee Pension IRA, universally known as the SEP-IRA, allows self-employed individuals to contribute up to twenty-five percent of net self-employment income up to the annual defined contribution limit with a dramatically simplified administrative structure that requires no annual reporting to the IRS, no formal plan document beyond a simple adoption agreement, and no actuarial calculations or complex compliance requirements. The SEP-IRA's combination of high contribution limits and minimal administrative burden has made it the most popular retirement savings vehicle for self-employed individuals and small business owners, effectively superseding the Keogh plan for most practical purposes.
The Solo 401(k) plan, also called the individual 401(k) or self-employed 401(k), allows self-employed individuals with no employees other than themselves and their spouse to make both employee elective deferral contributions, up to the annual 401(k) deferral limit which was twenty-two thousand five hundred dollars in 2023 with a seven thousand five hundred dollar catch-up contribution for participants age fifty and older, and employer profit-sharing contributions of up to twenty-five percent of compensation, potentially allowing total contributions significantly above what a SEP-IRA would permit for self-employed individuals with moderate income levels. The Solo 401(k) also allows Roth contributions in many plan designs, providing access to after-tax retirement savings that the traditional Keogh structure does not readily accommodate.
The SIMPLE IRA is available to self-employed individuals and small businesses with one hundred or fewer employees, providing a simplified retirement savings structure with lower contribution limits than the Keogh or SEP-IRA but with mandatory employer matching contributions that can be valuable for businesses seeking to provide retirement benefits to employees as well as the owner.
Rollover and Transition Considerations
For clients who established Keogh plans in prior decades and have maintained them, the question of whether to maintain the existing plan structure or roll the accumulated assets into a simpler alternative vehicle is a common planning consideration that investment advisers may encounter.
Assets in an existing Keogh plan can generally be rolled over to a traditional IRA, a SEP-IRA, or a new qualified plan without triggering immediate income taxation, provided the rollover is completed within sixty days of the distribution or is executed as a direct trustee-to-trustee transfer. Rolling assets from a Keogh plan to a traditional IRA eliminates the ongoing ERISA compliance requirements of the Keogh plan, simplifies account administration and reporting, and consolidates retirement assets in a single account structure that is easier to manage and monitor.
The decision to maintain an existing Keogh or roll to an IRA should consider the client's remaining years of plan contributions, the administrative burden and cost of maintaining the plan, the availability of creditor protection under applicable state law, and any specific plan features that may not be replicated in an IRA structure. In most cases, the simplicity and flexibility of rolling to a traditional IRA outweigh any advantages of maintaining the original Keogh structure for clients who are no longer making contributions.
Examination Relevance and Key Takeaways
The Keogh plan is tested on the Series 65 examination in the context of retirement planning for self-employed clients and the range of tax-advantaged retirement savings vehicles available to individuals with earned income from self-employment. Candidates must understand the definition and historical origins of the Keogh plan, the distinction between defined contribution and defined benefit Keogh structures, the applicable contribution limits and their tax treatment, the ERISA compliance requirements applicable to Keogh plans, and the comparison between Keogh plans and the more commonly used alternative vehicles including the SEP-IRA and Solo 401(k).
The core points to retain are these: the Keogh plan is a tax-advantaged qualified retirement plan for self-employed individuals and unincorporated businesses, established by the Self-Employed Individuals Tax Retirement Act of 1962 and named after Representative Eugene Keogh; defined contribution Keogh plans include profit-sharing plans with flexible contributions and money purchase plans with fixed contribution percentages, while defined benefit Keogh plans use actuarial calculations to determine contributions needed to fund a specified retirement benefit; contributions are tax-deductible and grow tax-deferred with withdrawals taxed as ordinary income and subject to a ten percent early withdrawal penalty before age fifty-nine and a half; Keogh plans are subject to full ERISA compliance requirements including Form 5500 annual reporting for multi-participant plans; the SEP-IRA and Solo 401(k) have largely superseded the Keogh plan for most self-employed individuals due to their comparable contribution limits and substantially lower administrative burden; and assets in existing Keogh plans can generally be rolled to a traditional IRA or SEP-IRA without current taxation through a direct rollover or sixty-day indirect rollover.
