A 401(k) plan can include an employer profit-sharing contribution in addition to employee salary deferrals. The key design question is not only how much the employer contributes, but also how that contribution is allocated among eligible participants.
What is 401(k) profit sharing?
In a 401(k) plan, employees can elect to defer part of their pay. The plan may also permit employer contributions. A profit-sharing contribution is an employer nonelective contribution: it does not depend on an employee choosing to defer from a paycheck.
The term can be confusing because the contribution does not have to be a literal distribution of accounting profits. The plan document controls the contribution formula and allocation method. Profit-sharing contributions are employer retirement-plan contributions credited to participant accounts.
The IRS describes profit-sharing contributions as flexible employer contributions and notes that a profit-sharing plan with a salary-deferral feature is a 401(k) plan. A plan still must satisfy applicable qualification, nondiscrimination, contribution-limit and document requirements.
How are profit-sharing contributions allocated?
The employer first decides the contribution under the terms of the plan. The plan then needs a method for allocating employer dollars among eligible participants. Several approaches can answer very different business questions.
| Method | Plain-English idea | Question it can answer |
|---|---|---|
| Pro rata | The same percentage of eligible compensation is allocated to covered participants. | What does a simple uniform contribution look like? |
| Flat dollar | The allocation is expressed as the same dollar amount, subject to plan terms and limits. | What happens if the employer wants equal dollars rather than equal percentages? |
| Age-weighted | Age influences the allocation because contributions are evaluated with retirement timing in mind. | How can age differences affect the design? |
| New Comparability | Participants can be placed into different allocation groups, subject to the plan document and nondiscrimination testing. | Can the contribution be targeted differently among owners or employee groups? |
There is no single allocation method that is automatically best. The useful starting point is the employer's objective: a simple uniform benefit, a fixed budget, a specific owner target, or different contribution goals for different people.
For a deeper comparison, see profit-sharing allocation methods and New Comparability versus pro rata profit sharing.
A simple profit-sharing example
Assume a business owner earns $300,000 and three employees earn a combined $150,000. The owner wants to see what a 10% pro rata employer contribution would cost before exploring anything more specialized.
| Participant | Compensation | Illustrated rate | Employer contribution |
|---|---|---|---|
| Owner | $300,000 | 10% | $30,000 |
| Employee A | $60,000 | 10% | $6,000 |
| Employee B | $50,000 | 10% | $5,000 |
| Employee C | $40,000 | 10% | $4,000 |
| Total | $450,000 | — | $45,000 |
A uniform 10% formula produces $30,000 for the owner and $15,000 for employees. That $45,000 total becomes a useful benchmark. A more specialized design should be compared against the same objective or the same budget—not against a moving target.
Illustration assumptions: A standalone defined contribution plan; all people shown are eligible for the illustrated employer contribution; compensation is eligible plan compensation; employee deferrals, catch-ups, matching contributions and fees are excluded. This is a fictional planning example, not a completed compliance test or funding instruction.
Where does New Comparability fit?
New Comparability is one way to allocate a profit-sharing contribution. Instead of automatically assigning the same percentage to every covered participant, the plan may use different allocation groups. The resulting design then must satisfy the applicable plan-document and nondiscrimination requirements.
For example, an employer may want to compare the $45,000 pro rata benchmark above with a design that directs a larger portion of the same budget toward an owner or other target participant. Whether that alternative works depends on the actual census, ages, compensation, ownership, contribution sources and plan terms.
The specialized analysis comes after the broader profit-sharing question. If that is the issue on your desk, read what a New Comparability profit-sharing plan is, then compare worked allocation examples.
What limits the contribution?
Several limits can matter at the same time. For 2026, the general defined contribution annual-additions limit is $72,000 per participant, before catch-up contributions, and the compensation limit used for plan purposes is $360,000. Employee elective deferrals have their own $24,500 regular limit for 2026.
Those individual limits are not the same thing as the employer's overall deduction limit, the amount required under a particular allocation formula, or the amount that will satisfy nondiscrimination testing. Plan terms can also be more restrictive than the statutory maximums.
If you are modeling an actual contribution, separate these questions: employee deferrals, employer match, employer profit sharing, catch-up contributions, annual additions and the employer's deduction limit. Combining them into one number can make a design look simpler than it really is.
What should you ask next?
Start with the business objective rather than a percentage. How much does the owner or target group want to receive? What is the acceptable employee budget? Is the priority simplicity, a fixed total employer cost, or maximizing a particular participant's employer contribution?
Then compare allocation methods on the same basis. A useful proposal should show owner dollars, employee dollars, total employer funding, the allocation method being used and which compliance tests still need to be completed.

Common 401(k) profit-sharing questions
Does a company need to have accounting profits to make a profit-sharing contribution?
Not necessarily. “Profit sharing” is the retirement-plan contribution label; the plan document controls how the employer contribution is determined and allocated. Start with the plan terms rather than assuming the contribution must equal a percentage of accounting profit.
Does the employer have to make a profit-sharing contribution every year?
Many profit-sharing contributions are discretionary, but the plan document and any applicable commitments still matter. Confirm the plan’s terms before treating a contribution as optional or deciding on the amount.
What is the difference between profit sharing and a 401(k) match?
A match is generally tied to employee elective deferrals. A profit-sharing contribution is an employer nonelective contribution and does not depend on an employee choosing to defer from pay.
Can owners receive a higher profit-sharing percentage than employees?
Potentially. New Comparability can use different allocation groups, but the plan document must support the approach and the final allocation must satisfy the applicable nondiscrimination and other qualification requirements.
What information is needed to compare profit-sharing allocations?
A useful review typically starts with the employee census, ages, eligible compensation, ownership and family relationships, existing employer contribution sources, the business objective and the current plan document. Aggregate payroll alone is not enough for a final testing conclusion.
What is the fastest way to see whether New Comparability may be worth exploring?
Start with the owner or target-participant contribution goal and the acceptable employee budget. Then compare a simple pro rata benchmark with a hypothetical New Comparability scenario using the free calculator. A formal design still requires the full facts and testing.
