Definition
A profit sharing plan is a defined contribution plan under which the employer makes discretionary contributions to participant accounts on a formula the employer establishes, historically funded from company profits though no actual profits are required under current tax law.
Why it matters
The profit sharing plan is the statutory ancestor of the modern 401(k) — the 401(k) provision was originally enacted as an elective-deferral feature that could be added to a profit sharing plan — and it remains a widely used plan form, either as a standalone arrangement or as the employer-contribution component of a 401(k) plan. Understanding it clarifies the structural distinction between employer discretionary contributions and participant elective deferrals within the broader DC plan universe.
How it works
A profit sharing plan is a defined contribution plan in which the employer makes contributions to participant accounts on a formula the employer establishes and reserves the right to change from year to year. The plan document specifies the allocation formula — commonly a percentage of each participant's compensation, or a pro rata share of a total contribution amount — and the employer decides each plan year whether and how much to contribute. Despite the name, contributions are not required to come from profits under current tax law; the employer may make a profit sharing contribution regardless of the company's financial results, subject to the plan document and applicable nondiscrimination requirements. Contributions are subject to the 415(c) annual additions limit ($72,000 for 2026, per IRS Notice 2025-67), which applies to combined employer and employee contributions across all defined contribution plans of the same employer. Distributions follow the standard DC plan restrictions: separation from service, death, disability, plan termination, age 59½, or financial hardship.
In practice
If you participate in a profit sharing plan, the operative facts are the allocation formula, the employer's contribution history, the vesting schedule that applies to employer contributions, and the plan's investment options. Because contributions are discretionary, the employer's actual contribution rate can vary substantially from year to year, and the plan document — not any marketing materials — is the source that specifies what the plan does and does not require the employer to contribute. When a profit sharing plan is combined with a 401(k) plan (common in current practice, with the profit sharing component functioning as the employer-contribution vehicle), the elective deferral rules apply to the 401(k) portion and the discretionary contribution rules apply to the profit sharing portion. A professional advising on profit sharing plan decisions should be able to name the specific allocation formula, the historical contribution pattern, and the vesting schedule.
In the Longevity Standard Framework
The profit sharing plan is one of the earlier DC plan forms and the statutory context in which the elective-deferral feature of the modern 401(k) was originally enacted. Where a profit sharing plan is combined with a 401(k) plan, the distinction between the two is the source of contributions (employer discretionary versus participant elective) rather than any structural difference in what the accumulated balance produces or how it can be converted to lifetime income.
