A Simplified Employee Pension (SEP) Plan is a written retirement plan document that authorizes an employer β including a self-employed individual β to make tax-deductible contributions to SEP-IRA accounts held by each eligible employee. Unlike a 401(k) or defined benefit plan, a SEP requires no annual IRS filing, no actuarial calculations, and no complex administration: the employer establishes the plan once in writing, determines a uniform contribution percentage each year, and deposits funds directly into participants' individual IRA accounts. The plan document specifies eligibility requirements, the compensation definition, the contribution formula, and the employer's disclosure obligations β creating the compliance record the IRS requires if the deduction is ever questioned.
Operating a SEP without a written plan document is not compliant β the IRS requires every SEP to be established under a formal written arrangement, whether using the agency's own Form 5305-SEP or a prototype document like this template. Without one, the entire deduction is at risk if your return is examined. Beyond IRS compliance, a written plan protects the employer from contribution disputes with employees, documents eligibility decisions for part-time and variable-schedule workers, and creates the notice trail required for annual participant disclosures. For self-employed professionals, completing this document before the tax-return deadline is the single step that locks in a deduction worth tens of thousands of dollars. This template gives you a ready-to-complete, structured plan document you can finalize in under an hour and retain indefinitely alongside your annual tax filings.

Why it matters: A plan document that names the business differently from IRS records creates a mismatch that triggers correction requests and can complicate the deductibility of contributions.
Fix: Use the exact business name as registered with the IRS and confirmed on the EIN assignment letter. Update the document if the business is restructured or renamed.
Why it matters: SEP rules require the same percentage of compensation to be contributed for all eligible participants. An owner who contributes 25% for themselves but 10% for staff violates the non-discrimination requirement.
Fix: Apply one uniform contribution percentage across all eligible participants in the same plan year. If the business cannot afford contributions for employees, consider suspending contributions for everyone that year.
Why it matters: Contributions deposited after the employer's tax-return due date β including extensions β are not deductible for the prior tax year, eliminating the primary tax benefit of the SEP.
Fix: Deposit contributions at least two weeks before the tax-return due date to allow for processing time at the financial institution.
Why it matters: Excluding a qualifying part-time worker or overlooking a former employee who met the service requirement can disqualify the plan or trigger correction under the IRS's Employee Plans Compliance Resolution System.
Fix: Run a formal eligibility check against payroll records before each year's contributions. Include employees who have since left if they met the eligibility requirements during the plan year.
Use the exact registered business name and the EIN as filed with the IRS. Set the effective date to the first day of the tax year in which contributions will first be made.
π‘ If you adopted the plan retroactively, the effective date can be as late as your tax-return due date including extensions β confirm with your tax advisor.
Choose minimum age (up to 21), years of service (up to 3 of the preceding 5), and minimum compensation (up to $750 indexed). You may use requirements less restrictive than the IRS maximums.
π‘ Using the most permissive eligibility rules (age 21, 3-year service, $750 compensation) maximizes the plan's reach and reduces the risk of inadvertently excluding eligible workers.
Enter the percentage of each eligible participant's compensation that the employer will contribute. The same percentage must apply to all eligible participants, including the owner.
π‘ A contribution rate between 10% and 25% is most common β start lower if cash flow is variable, since SEP contributions are discretionary and can be zero in any year.
Specify whether compensation means W-2 Box 1 wages, 415 compensation, or net self-employment income. Include or exclude bonuses and overtime explicitly, and reference the IRS annual compensation cap.
π‘ For self-employed individuals, net self-employment income must be reduced by the deductible portion of self-employment tax before applying the contribution percentage β a step many owners miss.
Confirm that contributions will be deposited by the tax-return due date including extensions. Document the financial institution holding each participant's SEP-IRA.
π‘ Open SEP-IRA accounts at the same institution to simplify deposits and annual contribution tracking.
Identify how and when eligible employees will receive a copy of the plan and annual contribution notices. A January 31 deadline for prior-year notices is standard.
π‘ Email delivery with read-receipt confirmation creates a timestamped record of notification that satisfies the disclosure requirement if the IRS requests proof.
The employer should date and retain the signed plan document permanently. Store a copy with annual tax filings and contribution records.
π‘ A SEP plan does not require filing with the IRS or DOL, but the plan document must be produced on request β keep it in the same folder as the employer's Form 5500 or tax return.
Each year, confirm the IRS contribution limit, the compensation cap, and the minimum compensation threshold, and update any figures stated in the document. Confirm eligibility lists before each year's contributions are made.
π‘ Set a recurring calendar reminder 30 days before your tax-return due date to review contribution calculations, update IRS limits, and deposit funds on time.
A SEP plan is a retirement arrangement that allows employers β including self-employed individuals β to make tax-deductible contributions to individual SEP-IRA accounts for each eligible employee. Contributions vest immediately, administration is minimal, and the plan requires no annual IRS filings. SEPs are one of the most widely used retirement vehicles for small businesses and sole proprietors because they offer high contribution limits with very low overhead.
For 2024, contributions are limited to the lesser of 25% of an eligible participant's compensation or $69,000. The compensation base used in the calculation is itself capped at $345,000 for 2024. Both limits are indexed for inflation annually. Self-employed individuals calculate their effective contribution rate slightly differently β typically about 20% of net self-employment income after the self-employment tax deduction.
The employer sets eligibility within IRS maximums: employees who are at least 21 years old, who have worked for the employer in at least 3 of the past 5 years, and who earned at least $750 (2024) in compensation during the year must be included. Employers may use less restrictive standards β for example, including employees after just one year of service β but cannot use more restrictive ones.
No. Under a standard SEP, only the employer contributes. Employees cannot make their own salary-deferral contributions to a SEP plan established after 1996. If employee contributions are a priority, a SIMPLE IRA or 401(k) plan is the appropriate alternative. However, employees are free to make their own regular IRA contributions separately, subject to income and contribution limits.
A SEP plan accepts only employer contributions, has a higher annual contribution limit ($69,000 in 2024), and requires no annual IRS filings. A SIMPLE IRA allows employee salary-deferral contributions up to $16,000 (2024) plus employer matching or non-elective contributions, but has a lower overall cap. SEPs are better suited to profitable businesses where the owner wants maximum tax-deductible contributions; SIMPLE IRAs are better when employee participation in their own retirement savings is a priority.
A SEP plan has no annual filing requirement with the IRS or the Department of Labor β unlike a 401(k), which requires Form 5500. However, the employer must maintain a written plan document and produce it on IRS request. Contributions are reported on the employer's tax return as a deduction, and financial institutions report SEP-IRA contributions on IRS Form 5498.
Yes. A SEP plan can be established and funded as late as the employer's tax-return due date, including extensions. For a sole proprietor on a calendar year with an October 15 extension, the plan can be set up and funded any time up to that date and still generate a deduction for the prior tax year. This is one of the SEP's key advantages over other retirement plans, which must generally be established by December 31.
Because all SEP contributions vest immediately and 100%, a departing employee retains full ownership of every dollar contributed to their SEP-IRA regardless of tenure. The former employee's SEP-IRA continues to grow tax-deferred, and they may roll it over to another IRA or retirement plan. The employer has no right to recapture or forfeit any contributed amounts.
If a part-time or seasonal worker meets all three eligibility requirements β age 21, at least 3 years of service in the past 5 years, and at least $750 in compensation during the year β the employer must make a SEP contribution for them at the same percentage applied to full-time employees. Many small business owners underestimate how many part-time workers qualify once they have worked for the business for three or more years.
A SIMPLE IRA allows both employer and employee contributions, making it better suited to businesses where employees want to save from their own paychecks. The SEP has a higher annual contribution ceiling ($69,000 vs. $16,000 employee deferral) and no annual filing requirement, but accepts only employer contributions. Use a SEP when the owner's tax deduction is the primary goal; use a SIMPLE IRA when employee participation in saving is important.
A Solo 401(k) is designed for owner-only businesses with no common-law employees. It allows both employee salary-deferral contributions ($23,000 in 2024) and employer profit-sharing contributions, potentially enabling higher total contributions than a SEP for self-employed individuals with lower net income. A SEP is simpler to administer and can cover employees; a Solo 401(k) is generally limited to the owner and their spouse.
A defined benefit plan promises a specific monthly retirement income rather than an account balance, and can allow significantly higher deductible contributions for older high-income owners. However, it requires annual actuarial calculations, mandatory contributions regardless of business performance, and Form 5500 filings. A SEP is far simpler and more flexible; a defined benefit plan is suited to established businesses with stable cash flow and owners aged 50 or older who want to maximize retirement savings rapidly.
An employee handbook describes the existence and general terms of a retirement benefit for employees to read at onboarding, but it is not the governing plan document. The SEP plan document is the operative legal instrument that defines eligibility, contributions, and compliance requirements. Both documents are needed: the plan document governs; the handbook communicates.
Attorneys, accountants, architects, and consultants use SEPs as a primary retirement strategy due to variable annual income and the flexibility to skip or adjust contributions in lower-revenue years.
Independent physicians and dentists in small practices use SEPs to maximize tax-deferred retirement savings while keeping plan administration separate from complex practice management obligations.
Small agencies and solo creative professionals use SEPs for their combination of high contribution limits and zero filing requirements, supporting retirement savings alongside fluctuating project-based revenues.
Small retail owners and online sellers with lean teams use SEPs as an affordable first step toward offering retirement benefits without the cost and complexity of a 401(k) plan.
