The maximum 401(k) contribution is not the maximum employer profit-sharing contribution. Employee deferrals and other annual additions use part of the same overall limit.
Separate the contribution buckets
Employee elective deferrals come from pay. Employer matching and nonelective contributions are funded by the business. For the annual-additions limit, regular deferrals and employer contributions generally share one ceiling; eligible catch-up contributions are outside that ceiling.
For 2026, the dollar ceiling is $72,000, also subject to the applicable 100%-of-compensation limit. The regular elective-deferral limit is $24,500. Those are ceilings, not a promise that every owner can receive that amount.
Example: calculate remaining employer room
| Contribution source | Amount |
|---|---|
| Regular employee deferral | $24,500 |
| Safe harbor nonelective already allocated | $9,000 |
| Additional employer room, before other constraints | $38,500 |
| Total annual additions | $72,000 |
The owner has $47,500 of total employer room in this simplified example, but $9,000 is already being used. Adding another $47,500 would double-count the safe harbor contribution.
This assumes no other annual additions or relevant aggregated-plan contributions. Catch-ups are separate and depend on age and plan eligibility. The employer allocation still has to satisfy the document, testing and deduction rules.
Compare a target, not only the maximum
An owner may prefer a $35,000 employer contribution if reaching $47,500 requires a much larger employee contribution. Ask for two or three meaningful targets, with the total employer cost beside each.
| Option | Owner employer contribution | Employee employer contributions | Total |
|---|---|---|---|
| Lower target | $35,000 | $10,000 | $45,000 |
| Higher target | $45,000 | $15,000 | $60,000 |
Here, another $10,000 for the owner requires another $15,000 of business funding. The decision depends on the owner’s savings goal and the value the business places on the additional employee benefit.
How profit-sharing allocation changes employee cost
Contribution room answers how much an owner could potentially receive. The allocation method answers a different question: what does the business have to contribute for everyone else to support that objective?
Assume an owner earns $300,000 and wants a $45,000 employer contribution. Three eligible employees earn $150,000 in total. A uniform 15% pro rata profit-sharing formula would provide the same 15% of compensation to the employees. A proposed New Comparability illustration could instead model a 5% employee rate, subject to the plan document and testing.
| Allocation illustration | Owner | Employees | Total employer funding |
|---|---|---|---|
| Pro rata at 15% | $45,000 | $22,500 | $67,500 |
| New Comparability illustration | $45,000 | $7,500 | $52,500 |
The owner target is identical, but the illustrated employee funding differs by $15,000. The New Comparability row is not a passing test result; it is the economic question a full census and plan document must validate.
That is why an owner-contribution conversation should compare profit-sharing allocation methods, not just calculate an individual maximum.
Contribution capacity is not tax savings
A $45,000 contribution is money funded into a retirement account. Its current tax effect depends on the entity, deduction rules and individual circumstances. It is not a $45,000 reduction in taxes owed.
For S corporation owners, shareholder distributions are not retirement-plan compensation. Partners and sole proprietors require an earned-income calculation. Confirm compensation before treating the preliminary allocation as available.
Questions to answer before funding
- What is the owner’s actual employer-contribution target? Do not assume the maximum is the goal.
- Which contribution sources are already using the annual limit? Include prior employer contributions before calculating what remains.
- What employee budget is acceptable? Compare owner dollars, employee dollars and total funding together.
- What allocation method does the plan permit? Start with profit-sharing fundamentals and the allocation-method comparison.
- What still has to be tested? A gateway calculation or illustrative percentage is not a final nondiscrimination result.
Once those facts are clear, use the profit-sharing and New Comparability calculator to frame the scenario before requesting a full design.
