401k profit sharing rules

Profit sharing in a 401(k) plan is a popular method for employers to contribute to their employees’ retirement savings. This mechanism not only incentivizes employees by aligning their retirement benefits with the company’s financial success, but it also offers flexibility for employers in how and when contributions are made. Here, we will explore the key rules and considerations surrounding 401(k) profit sharing.

What is 401(k) Profit Sharing?

A 401(k) profit sharing plan allows employers to make discretionary contributions to their employees’ retirement savings based on the company’s earnings. Unlike standard 401(k) plans where employee deferrals are a primary component, profit sharing plans give employers the ability to boost their employees’ retirement savings independently of employee contributions.

Eligibility and Contributions

Eligibility Requirements:

Employers can set eligibility requirements for participation in profit sharing. Common criteria include having reached a certain age (often 21 years) and having completed a specific period of service (typically one year).

However, these requirements must be designed to not discriminate in favor of highly compensated employees.

Contribution Limits:

For 2023, the total contribution limit (from both employee and employer) to a 401(k) plan is $66,000 or 100% of the employee’s compensation, whichever is less. This limit includes employee deferrals, employer matching contributions, and profit sharing.

Discretionary Contributions:

One of the hallmarks of profit sharing is that contributions are discretionary. Employers are not obligated to make contributions every year. They can decide each year whether to contribute based on the company’s financial performance.

Allocation Formulas

Profit sharing contributions can be allocated to employees’ accounts using different formulas:

Pro-rata: Contributions are made as a uniform percentage of each eligible employee’s salary.

Age-weighted: Contributions take into account an employee’s age and compensation, benefiting older employees who are closer to retirement.

New comparability or cross-tested: Different groups of employees receive different rates of contributions, often to favor certain employees like owners or highly compensated individuals, while still passing nondiscrimination testing.


Vesting schedules determine when employees own the contributions made to their accounts. Employers can set up their own schedules for vesting, ranging from immediate vesting to graded or cliff vesting over several years. This can be a tool for employee retention.

Compliance and Testing

401(k) profit sharing plans are subject to various compliance tests to ensure they do not disproportionately favor highly compensated employees:

The Actual Deferral Percentage (ADP) and Actual Contribution Percentage (ACP) tests: These tests compare the deferral percentages and employer contribution percentages of highly compensated employees against those of non-highly compensated employees.

Top-Heavy Test: This test ensures that the key employees’ accounts do not contain more than 60% of the total assets in the plan.

Employers may use additional contributions or plan design changes to correct any disparities identified in these tests.

Tax Benefits

Both employers and employees benefit from tax advantages through 401(k) profit sharing. Contributions are tax-deductible for the employer and are tax-deferred for the employee. Furthermore, by offering a 401(k) profit sharing plan, employers might reduce their business tax liability while simultaneously improving employee satisfaction and retention.

401(k) profit sharing plans offer a flexible and powerful tool for employers to contribute towards their employees’ futures. By understanding the various rules and regulations that govern these plans, both employers and employees can better leverage this benefit for mutual advantage. As these plans are complex and subject to changing regulations, it’s often advisable for businesses to consult with financial professionals to ensure compliance and optimal structuring of their profit sharing arrangements.

Implementing and Managing a 401(k) Profit Sharing Plan
Implementing a 401(k) profit sharing plan requires careful planning and ongoing management to ensure compliance and to maximize its benefits. Here’s how employers can effectively implement and manage these plans:

Plan Design

Choosing the Allocation Formula:

The choice of allocation formula should align with the company’s goals for the plan, whether it’s to provide uniform benefits, favor older employees, or benefit key employees. Each formula impacts the plan’s testing and compliance differently, so it’s crucial to choose wisely based on company demographics and objectives.

Setting Vesting Schedules:

Employers should consider their workforce’s turnover rate and retention goals when setting vesting schedules. More immediate vesting can be a great incentive for new talent, while longer vesting schedules might better serve retention goals.

Defining Eligibility Criteria:

Clearly defined eligibility criteria help ensure that the plan benefits are offered fairly and in accordance with the company’s policy. This helps in maintaining transparency and trust among employees.

Implementation Process

Partnering with Financial Institutions:

Choosing the right financial institution or plan administrator is critical. These partners can provide valuable assistance in plan setup, administration, and compliance monitoring.

Employee Communication:

Effective communication is key to helping employees understand the benefits of the plan. Employers should provide clear information about how the profit sharing works, how contributions are calculated, and how these contribute to their retirement goals.

Documentation and Compliance:

Maintaining proper documentation is essential for compliance and for addressing any disputes that might arise. This includes plan documents, amendments, and records of contributions and tests.

Ongoing Management and Compliance

Annual Testing:

Regular testing for discrimination and top-heavy status is required to ensure that the plan remains compliant with IRS rules. These tests can be complex, often requiring input from financial advisors or third-party administrators.

Regular Reviews and Adjustments:

It’s wise to review the plan’s performance and structure regularly, ideally annually. This review can include checking if the plan still meets the company’s financial and operational goals, as well as ensuring that it remains compliant with current laws and regulations.

Handling Contributions and Distributions:

Managing contributions each year based on profitability and ensuring correct distributions during employee separations or retirements requires diligent oversight. Mistakes in these areas can be costly in terms of penalties and lost trust.

Best Practices for Maximizing Impact

Offer Matching Contributions:

While not required, adding an employer match to the profit sharing can greatly increase employee participation and savings rates.

Educate Employees:

Regularly educating employees on financial wellness and the importance of retirement planning can enhance the perceived value of the profit sharing plan.

Monitor Industry Trends:

Keeping an eye on trends and benchmarks within the industry can help ensure that the plan remains competitive and attractive to employees.

Profit sharing within a 401(k) framework presents a versatile and impactful employee benefit. With thoughtful implementation and careful management, employers can provide a significant boost to their employees’ retirement readiness while reaping financial and strategic benefits for their business. As regulations and economic conditions evolve, staying informed and adaptable will be key to maintaining an effective profit sharing plan.
