What Is a Keogh Plan? A Complete Guide to Retirement Savings for Self-Employed Individuals

Retirement planning is one of the most important financial decisions business owners and self-employed individuals will make. While traditional employees often have access to employer-sponsored 401(k) plans, entrepreneurs and independent professionals must take responsibility for building their own retirement savings.

One retirement savings option that has existed for decades is the Keogh plan. But what is a Keogh plan, how does it work, and is it still a good retirement strategy today?

A Keogh plan is a tax-advantaged retirement plan designed primarily for self-employed individuals and owners of unincorporated businesses. Although newer retirement options have become increasingly popular, Keogh plans can still provide substantial tax benefits and retirement savings opportunities.

Understanding how a Keogh plan works can help business owners determine whether this retirement arrangement fits their long-term financial goals.

What Is a Keogh Plan?

A Keogh plan is a qualified retirement savings plan established by a self-employed individual or an eligible business owner. Named after U.S. Representative Eugene Keogh, who helped introduce the legislation that created these retirement arrangements in 1962, the plan was designed to give self-employed workers access to retirement benefits comparable to those available to traditional employees.

Today, the term Keogh plan generally refers to certain qualified retirement plans maintained by self-employed individuals or unincorporated businesses. These plans may take the form of a defined contribution plan or a defined benefit pension plan.

Like traditional employer-sponsored retirement accounts, a Keogh plan can provide tax advantages that encourage long-term investing.

One important distinction is that Keogh plans are not a separate retirement plan category under modern tax law. Instead, the term describes certain qualified retirement arrangements, such as profit-sharing, money purchase pension, and defined benefit plans.

How Does a Keogh Plan Work?

A Keogh plan allows an eligible business owner to contribute money toward retirement through a qualified retirement arrangement. Depending on the structure selected, contributions may be based on business earnings, a predetermined contribution formula, or the amount necessary to fund a future pension benefit.

Money contributed to a traditional Keogh plan generally receives tax-deferred treatment. This means eligible contributions may reduce current taxable income, while investment earnings accumulate without annual income taxation inside the plan. Taxes are generally paid when retirement distributions are received.

For example, imagine a self-employed consultant who earns $200,000 annually and establishes a qualified profit-sharing plan commonly described as a Keogh plan. The consultant may be able to contribute a significant portion of eligible compensation to the retirement account, subject to applicable IRS limits.

Those contributions can potentially reduce current taxable income while helping the business owner accumulate retirement savings. Over several decades, tax-deferred compounding can create substantial wealth. You can model that growth with our compound interest calculator.

Types of Keogh Plans

There are two primary categories of retirement arrangements commonly associated with Keogh plans.

1. Defined Contribution Keogh Plan

A defined contribution Keogh plan establishes an individual retirement account balance based on contributions and investment performance. Two traditional examples include profit-sharing plans and money purchase pension plans.

Profit-sharing plans allow employers to make contributions according to a written plan formula. Contributions can generally vary from year to year, providing flexibility when business income fluctuates.

Money purchase pension plans typically require employers to contribute a specified percentage of eligible compensation annually.

With either arrangement, the final retirement account balance depends on contributions, investment returns, fees, and withdrawals.

2. Defined Benefit Keogh Plan

A defined benefit Keogh plan operates more like a traditional pension. Instead of focusing on annual account contributions, the plan promises a retirement benefit calculated using a predetermined formula. Factors may include compensation, years of service, and retirement age.

An actuary determines the contributions necessary to fund the promised retirement benefit. Defined benefit plans can sometimes permit significantly larger deductible contributions than defined contribution plans, particularly for older, high-income business owners.

However, these plans generally involve greater administrative complexity, ongoing funding obligations, and higher professional expenses.

Who Qualifies for a Keogh Plan?

A Keogh plan is primarily associated with individuals earning income through self-employment or an unincorporated business. Potentially eligible individuals include:

• Sole proprietors operating their own businesses.
• Independent consultants and contractors.
• Physicians, dentists, and attorneys operating eligible practices.
• Partners in partnerships.
• Other qualifying self-employed professionals.

An important consideration is that eligible employees generally cannot be excluded simply because the owner wants to maximize personal retirement contributions. A business owner with employees may be required to include qualifying workers and make contributions on their behalf. This can significantly increase the overall cost of maintaining a Keogh plan.

Additionally, owners of incorporated businesses can sponsor qualified retirement plans, although those arrangements generally are not described as Keogh plans under the traditional terminology.

Keogh Plan Contribution Limits for 2026

One of the biggest advantages of a Keogh plan is its potential for substantial retirement contributions. However, contribution limits depend on the specific qualified plan structure.

For 2026, the IRS defined contribution annual additions limit is $72,000, subject to applicable compensation limits and plan rules. A self-employed individual contributing to a profit-sharing plan is generally limited to an employer contribution based on approximately 20% of adjusted net earnings from self-employment, up to the applicable annual limit. The exact calculation requires adjustments for self-employment taxes and other applicable factors.

Defined benefit Keogh plans operate differently. Their contribution requirements are based on actuarial calculations and applicable pension funding rules rather than a simple annual contribution percentage. For 2026, the maximum annual benefit permitted under the general defined benefit plan limit is $290,000, subject to additional legal limitations.

These higher potential funding amounts can make defined benefit arrangements attractive to certain high-income professionals approaching retirement. Because IRS limits can change annually, business owners should verify current figures before making contributions.

Tax Advantages of a Keogh Plan

The tax treatment of a Keogh plan is one of its most attractive features.

Tax-Deductible Contributions

Eligible contributions to a traditional Keogh plan are generally deductible, subject to IRS requirements. For a business owner in a relatively high marginal tax bracket, retirement contributions can produce meaningful current-year tax savings.

Tax-Deferred Investment Growth

Investments inside a traditional Keogh plan generally grow without annual federal income taxation. Dividends, interest, and capital gains can remain invested, allowing the account to benefit from long-term compounding.

Retirement Income Planning

A Keogh plan can help business owners build retirement assets separate from their businesses. This diversification is particularly important for entrepreneurs whose personal wealth may be heavily concentrated in business ownership.

However, traditional plan distributions are generally taxable as ordinary income, and withdrawals before age 59½ may trigger an additional 10% tax unless an exception applies. Required minimum distribution rules also apply. For a related discussion of building a personal pension, see our guide to an individual pension plan.

Keogh Plan vs. Solo 401(k)

Many self-employed individuals considering a Keogh plan should also evaluate a Solo 401(k). A Solo 401(k) is designed for a business owner with no eligible employees other than a spouse. The following comparison highlights several important differences.

A Solo 401(k) may allow a business owner to contribute more at lower income levels because it permits employee elective deferrals in addition to employer contributions. For 2026, the regular employee elective deferral limit for a 401(k) is $24,500, with additional catch-up contributions available to eligible participants.

A defined benefit Keogh arrangement, however, may support substantially higher retirement funding for certain high-income individuals. The best option depends on earnings, age, employees, and retirement objectives.

Advantages and Disadvantages of a Keogh Plan

Before establishing a Keogh plan, business owners should understand both the benefits and limitations.

Advantages

• Higher retirement savings potential: Certain qualified retirement arrangements permit substantial annual contributions, particularly defined benefit plans.
• Tax advantages: Eligible contributions can reduce current taxable income while investments grow tax-deferred.
• Retirement flexibility: Business owners can select plan structures suited to their income and retirement goals.
• Long-term financial security: A Keogh plan can help entrepreneurs accumulate retirement assets independently of the value of their businesses.

Disadvantages

• Administrative requirements: Qualified plans must comply with IRS and Department of Labor requirements, where applicable.
• Professional costs: Some plans require specialized administration, actuarial services, or annual filings.
• Employee obligations: Business owners may need to cover eligible employees and contribute toward their retirement benefits.
• Limited access to funds: Early withdrawals can trigger income taxes and penalties.
• Complex contribution calculations: Self-employed contribution limits can be more complicated than those associated with an IRA.

How to Set Up a Keogh Plan

Establishing a Keogh plan generally involves working with a qualified retirement plan provider, financial institution, or third-party administrator.

The process begins by selecting the appropriate qualified retirement plan structure. Next, the business owner adopts a written plan document that establishes eligibility requirements, contribution formulas, vesting provisions, and distribution rules. A qualified custodian or trustee may then be selected to hold the plan assets.

The business owner must also establish appropriate recordkeeping procedures and meet applicable reporting requirements. Certain qualified plans must file Form 5500 or another applicable annual return.

Plan establishment deadlines vary by plan type and circumstances. Some employer-funded qualified plans may be adopted by the business's tax return filing deadline, including extensions, but special timing rules apply to elective deferrals and other plan provisions. Professional guidance is especially important when establishing a defined benefit arrangement.

Is a Keogh Plan Better Than a SEP IRA?

A SEP IRA is another popular retirement savings option for self-employed individuals. Both arrangements may allow substantial tax-deductible contributions.

However, SEP IRAs are generally easier to establish and maintain because they typically involve fewer administrative requirements than qualified pension plans.

A Keogh plan may provide additional design flexibility, particularly when structured as a defined benefit pension. For a self-employed professional with relatively straightforward retirement needs, a SEP IRA may be sufficient. For a business owner seeking a customized retirement arrangement or potentially larger pension funding opportunities, a qualified plan traditionally described as a Keogh plan may be worth considering.

Frequently Asked Questions About Keogh Plans

Is a Keogh plan the same as a 401(k)?

Not exactly. Keogh is an older term describing certain qualified retirement plans for self-employed individuals. A 401(k) is a specific type of qualified defined contribution retirement arrangement. Both can offer tax-advantaged retirement savings.

Can you withdraw money from a Keogh plan before retirement?

Withdrawals depend on the plan's distribution provisions and applicable law. Early taxable distributions may be subject to a 10% additional tax unless an exception applies.

Can a Keogh plan be rolled over into an IRA?

Generally, eligible rollover distributions from a qualified Keogh plan can be transferred to a traditional IRA or another eligible retirement plan without immediate taxation when rollover requirements are satisfied.

Can you have a Keogh plan and an IRA?

Yes. An eligible individual can generally maintain both a Keogh plan and an IRA. However, IRA deduction eligibility and qualified plan contribution limits must be evaluated separately.

Are Keogh plans still available?

Yes. Although the term Keogh plan is less commonly used today, the underlying qualified retirement arrangements remain available under current retirement plan rules.

Final Thoughts: Is a Keogh Plan Right for You?

Understanding what is a Keogh plan is an important step for self-employed individuals who want to maximize retirement savings and potentially reduce their tax burden.

While Keogh plans have become less prominent with the growth of Solo 401(k)s and SEP IRAs, certain qualified retirement arrangements still offer valuable benefits for business owners. A Keogh plan may be particularly attractive to higher-income entrepreneurs interested in substantial retirement contributions or defined benefit pension arrangements.

However, administrative costs, employee coverage requirements, contribution rules, and long-term financial objectives must all be considered.

Ultimately, the best retirement strategy is one that allows you to consistently save, invest wisely, and accumulate enough assets to make work optional. Whether you choose a Keogh plan, Solo 401(k), SEP IRA, or another retirement account, the most important decision is to begin planning early and remain committed to building long-term financial independence.
