Simplified Employee Pension Plans: Core Rules for Producers

A SEP gives an employer a relatively straightforward way to make retirement contributions through individual retirement accounts. The employer contributes; employees generally do not make salary-deferral contributions to a traditional SEP arrangement.

How the plan works

The employer adopts a written SEP arrangement and contributes to SEP-IRAs for eligible employees. Contributions are discretionary from year to year, but if the employer contributes for itself, it must follow the plan’s allocation formula for eligible employees. SEP contributions are immediately vested; the employee owns the IRA assets.

Eligibility and equal allocation

Federal rules generally require coverage for an employee who meets the plan’s age, service, and compensation criteria, subject to permitted exclusions. A commonly used model SEP covers an employee who is at least 21, worked for the employer in at least 3 of the last 5 years, and received the minimum compensation specified for the year. The employer may use less restrictive eligibility rules but cannot make them more restrictive than the legal maximums. If a contribution is made for the owner, eligible employees generally receive contributions at the same percentage of compensation.

SEP is not a SIMPLE IRA

A traditional SEP is funded by employer contributions and does not operate like a salary-reduction 401(k). A SIMPLE IRA has employee salary-reduction contributions and required employer contributions under its rules. Do not mix their contribution mechanics or notice requirements. Tax limits change over time, so consult current IRS guidance for a particular year.

Eligibility and nondiscrimination in practice

An employer must apply its written SEP eligibility provisions consistently. The familiar model criteria—age 21, service in at least three of the prior five years, and minimum compensation—are maximum exclusion limits for the model arrangement, not mandatory hurdles every employer must impose. A plan can be more generous by using less restrictive eligibility rules.

Certain employee categories may be excluded under permitted rules, such as employees covered by a collective bargaining agreement where retirement benefits were bargained for in good faith, or certain nonresident aliens with no U.S.-source earned income. Check current IRS instructions for the tax year and the actual plan document before excluding anyone.

Worked allocation example

Suppose an employer makes a 10% SEP contribution for itself based on compensation under the plan formula. Eligible employees generally receive the same contribution percentage applied to their plan-defined compensation, subject to statutory limits. If one eligible employee has $40,000 in compensation, a simplified 10% illustration would be $4,000 before applying annual caps and definitions.

Do not allocate only to employees the owner prefers or vary the percentage by job title unless the plan and applicable rules permit the design. If the employer contributes for the owner, the contribution rate generally must be applied for eligible employees under the SEP’s allocation terms.

SEP limits, ownership, and timing

Employer contributions are subject to annual dollar limits and compensation caps that change over time. The IRS publishes current limits and contribution deadlines; avoid memorizing an outdated dollar figure for a reusable article. Contributions are placed in employee SEP-IRAs and are immediately vested, so the employer does not retain a forfeitable employer-contribution balance as it might under some qualified plans.

Employees control their IRA investments subject to account rules. Withdrawals generally follow IRA distribution and tax rules, including potential tax and early-distribution consequences. The SEP is a retirement arrangement, not a promise that the employee receives a guaranteed pension amount.

Compare SEP with SIMPLE and 401(k)

A traditional SEP is funded by employer contributions. A SIMPLE IRA permits employee salary-reduction contributions and requires employer contributions under its own formula. A 401(k) plan permits salary deferrals and can include employer match or profit-sharing contributions, with more extensive plan administration.

For exam questions, identify who contributes, whether employee deferrals are allowed, how employer contributions are calculated, vesting, and eligibility. Remember the narrow historic SARSEP exception for qualifying older plans rather than broadly saying no SEP arrangement ever permits salary reduction.

Employer action checklist

An employer considering a SEP should select the document or IRS model arrangement, define eligibility, calculate the permitted employer contribution, and ensure every eligible employee receives the required notice and contribution. Reconcile payroll records with the definition of compensation and keep evidence of allocation calculations. If the employer has more than one plan, coordinate contribution limits and coverage testing.

A sole proprietor’s own SEP contribution uses a special calculation based on adjusted net earnings from self-employment, not simply the employee percentage applied to gross business receipts. IRS Publication 560 explains the calculation. An agent should avoid calculating a self-employed client’s contribution from a round revenue figure without accounting for the tax rules.

Producer’s year-end review

At year end, reconcile who met the plan’s eligibility rules, which compensation definition applies, the contribution percentage, and the amount deposited to each SEP-IRA. Verify that the employer contribution was deposited by the applicable tax-filing deadline, including extensions where allowed, and that required employee notices were provided.

Compare the employer’s contribution with the current IRS limit and any compensation cap for that tax year. Limits change periodically. Use the IRS publication for the year in question rather than a stale calculator or a prior-year figure.

For a self-employed owner, calculate the contribution using IRS rules for net earnings from self-employment; the owner’s rate is not simply applied to gross receipts. A tax professional can confirm the deductible amount and coordinate the SEP with any other retirement plan.

Keep year-specific figures current

SEP compensation and contribution limits can change annually. A study answer that does not require a dollar figure should emphasize eligibility, employer funding, allocation, and vesting. If a question supplies a tax year and asks for a limit, consult the IRS value for that year rather than relying on a memorized historical amount.

Exam takeaway

Think employer-funded IRA, discretionary contribution decisions, same percentage for eligible workers, and immediate vesting. Determine eligibility using the plan and current federal rules.
