Key Points

For Keogh purposes: a sole proprietor is his or her own employer, and a partnership is the employer of each partner. Only the partnership (not an individual partner) may establish a Keogh plan — a minority partner needs majority approval from the other partners.
A self-employed person must have earned income from personal services actually rendered and be subject to self-employment (SE) tax. Passive investors, S corporation shareholders, and limited partners generally do not qualify as self-employed for Keogh purposes.
An owner-employee is a sole proprietor or a partner who owns more than 10% of the capital or profit interest in a partnership. Only owner-employees and regular employees may be covered by a Keogh — no others.
Keogh contributions are based on earned income from the specific business that maintains the plan — not from other businesses the owner may operate.
When computing net earned income, the owner must deduct one-half of self-employment taxes and the Keogh contribution itself before applying the contribution rate. This creates a circular calculation resolved by converting the plan’s stated rate to a reduced percentage: nominal rate ÷ (1 + nominal rate).
A plan’s stated contribution rate of 25% of post-contribution income is equivalent to approximately 20% of pre-contribution income — the maximum effective rate for owner-employees.

“Employer” Defined

Qualified plans must be established by “an employer.” For unincorporated businesses, the term is specifically defined:

  • A sole proprietor (an individual owning the entire interest in an unincorporated business) is considered to be his or her own employer.
  • A partnership is considered to be the employer of each partner.

This has an important practical consequence: since a qualified plan must be a plan of an employer, an individual partner cannot establish a Keogh plan for himself alone — only the partnership as a whole may do so. A partner without a controlling interest must secure agreement from a voting majority of the other partners before the partnership can establish a Keogh plan.

“Self-Employed Person” and Personal Services

A self-employed person, for Keogh purposes, is generally anyone who has earned income from personal services actually rendered and who is subject to self-employment tax under Social Security (with limited exceptions). The key is that the individual’s personal efforts must be involved in generating the income.

Personal Services Requirement

Mere financial backing of a business is not sufficient — the individual must actively work in it. As a result:

  • Most limited partners are not considered self-employed for retirement plan purposes. Distributions of profit to them are investment income, not earned income.
  • S corporation shareholders are not considered self-employed. Pass-through income from an S corporation does not constitute net earnings from self-employment.
  • A retired partner who performs no services and holds no interest in the partnership is not self-employed merely because he or she receives partnership retirement benefits.
Consulting Fees and Royalties

A retiree may earn self-employment income from consulting fees, provided actual services are performed. However, courts have ruled that an exclusive consulting arrangement with a former employer may violate the self-employed definition — retirees should be available to serve more than one client.

Royalties and licensing payments to an inventor or author for property they created through their own efforts are treated as self-employment income. However:

  • The sale of a patent or copyright is treated as the sale of a capital asset — not self-employment income.
  • Royalties paid for one’s name or reputation (not for property created through personal effort) are not self-employment income.

“Owner-Employee” and “Employee”

Owner-Employees

Self-employed individuals fall into two categories for Keogh purposes: those who are owner-employees and those who are not. An owner-employee is a self-employed person who:

  • owns the entire interest in an unincorporated trade or business (a sole proprietor), or
  • in a partnership, is a partner who owns more than 10% of the capital interest or profit interest of the partnership.

The partnership agreement ordinarily governs a partner’s capital and profit interest percentages.

Regular Employees

An employee, for Keogh purposes, is someone who owns no part of the business and works for a self-employed person. Employees do not have the right to establish a Keogh plan themselves, but may be covered as participants by a Keogh plan established by their employer.

Example — Employee vs. Owner-Employee

Paul Drake is a private investigator working for Perry Mason, a self-employed attorney. Paul is an employee — he cannot establish a Keogh plan based on his work for Mr. Mason. However, he may be included as a participant in any Keogh plan Mr. Mason establishes.

If Paul also sets up his own separate investigative firm — Moonlight Detectives — he can establish a Keogh plan for that business, based on the earnings from Moonlight. His income from Mr. Mason would not count toward that Keogh.

Earned Income & Net Earned Income

Keogh plan contributions on behalf of self-employed individuals — including owner-employees — are based on earned income: gross income derived from a sole proprietorship or partnership, less allowable business deductions. Contribution limits for Keogh plans are the same as those for corporate plans (see ch62).

If an owner-employee operates more than one business but only one has a Keogh plan, contributions to that plan may only be based on earned income from the business that maintains the plan — not from the owner’s other businesses.

Example — Multiple Businesses

Jeff is a sole-practitioner attorney with three employees. He also holds a 40% interest in Striders Shoe Store (a partnership with Hank, who owns 60%). Striders maintains a Keogh plan.

Jeff may participate in Striders’ Keogh plan without being required to also establish a Keogh for his law office employees. However, contributions to the Striders Keogh on Jeff’s behalf may only be based on his earned income from the shoe store — not his law practice income.

Net Earned Income — The Circular Calculation

When computing the deductible Keogh contribution for an owner-employee, the following items must be subtracted from net earnings before applying the contribution rate:

  • a deduction for one-half of the self-employment tax paid (the employer-equivalent portion), and
  • a deduction for the Keogh contribution itself on behalf of the self-employed person.

This second deduction creates a circular calculation: the contribution depends on net income, but net income is reduced by the contribution. The IRS resolves this by expressing the contribution as a reduced percentage of pre-contribution income:

Reduced % = Nominal Rate ÷ (1 + Nominal Rate)
Plan Rate (% of post-contribution income) Effective Rate (% of pre-contribution income) Formula
5%4.7619%5% ÷ 105%
10%9.0909%10% ÷ 110%
15%13.0435%15% ÷ 115%
20%16.6667%20% ÷ 120%
25%20.0000%25% ÷ 125%

The maximum plan contribution rate of 25% of post-contribution income translates to an effective rate of 20% of pre-contribution (gross) income. This is the same ~20% effective rate discussed for SEP-IRAs and applies for the same mathematical reason.

Example — Jackson’s Keogh Contribution

John Jackson is a sole proprietor with employees. His Keogh plan requires a 15% contribution for all participants. For the tax year, net earnings from the business are $131,000 (after paying employees and their Keogh contributions, but before Jackson’s own contribution).

Step 1 — Convert the nominal 15% rate to the effective pre-contribution rate:
15% ÷ 115% = 13.0435%

Step 2 — Subtract the deductible half of SE tax:
SE tax on the FICA wage base portion: $131,000 × 15.3% (on relevant base) ÷ 2 = approx. $4,406 deduction
Net after SE tax deduction: $131,000 − $4,406 = $126,594

Step 3 — Apply the reduced rate:
$126,594 × 13.0435% = $16,512 deductible Keogh contribution for Jackson
