Introduction to Cash Balance Plans

A 401(k) profit sharing plan already plays a role in many business owners’ retirement strategy. Still, there are times when maximizing that plan may not fully align with an owner’s savings goals or current tax situation. In those cases, a cash balance plan may be worth exploring as part of a broader retirement planning approach.

Defined Contribution vs. Defined Benefit

A cash balance plan is one type of defined benefit plan. Defined benefit plans are built around a promised retirement benefit, while defined contribution plans, such as 401(k) plans, are built around contributions made to an individual account. 

In a defined contribution plan, the participant’s retirement outcome depends on contributions, investment performance, and time. In a defined benefit plan, the retirement benefit is the target, and the employer funds the plan to support that outcome.

How Cash Balance Plans Work

What often makes a cash balance plan easier to understand is the way it is presented to participants. Rather than seeing a traditional pension formula, participants see a hypothetical account balance. That account generally receives two credits: a pay credit, which may be based on compensation or a flat dollar amount, and an interest credit, which helps grow the value of the benefit over time. The format can feel familiar, even though the plan remains a defined benefit arrangement behind the scenes.

This structure is one reason cash balance plans can appeal to business owners who want to save more for retirement. In some cases, they may allow for larger employer contributions than a 401(k) plan alone, and those contributions are generally tax deductible. The contributions also grow tax deferred within the plan. For owners who are already taking full advantage of their 401(k) profit sharing plan, that added capacity can be meaningful.

Cash balance plans are often discussed alongside 401(k) profit sharing plans because the two may work well together. A business may first evaluate the opportunities available through its existing 401(k) structure, then determine, based on its specific objectives, demographics, and testing results, whether a cash balance plan could support additional retirement savings.

Demographics, compensation levels, and plan testing all play a role, which is why these decisions usually call for careful coordination among the employer, Plan Advisor, actuary, and third-party administrator.

Responsibilities and Tradeoffs

At the same time, cash balance plans come with important responsibilities. Unlike discretionary profit sharing contributions, cash balance plan contributions are generally mandatory each year once the plan is established. These plans are generally designed as part of an ongoing retirement strategy rather than a short-term contribution objective, so they may be a better fit for businesses with steady cash flow and a long-term commitment to the strategy. Adopting a plan primarily for a single strong year without a longer-term commitment may not be appropriate and should be evaluated carefully with the employer’s legal, actuarial, tax, and plan administration advisors. 

Investment management is another key distinction. Even though participants see a hypothetical account balance, the assets are not typically directed by each participant the way they are in a 401(k). Instead, the assets are managed at the plan level. That means investment performance can affect the plan’s funded status, and losses or underperformance relative to the interest crediting rate may lead to higher required employer contributions over time. Because of that, investment strategy is usually designed with a focus on long-term funding needs, liability awareness, and risk management rather than simply chasing returns.

There are also compliance and administrative considerations to weigh. Cash balance plans operate within a stricter regulatory framework than many employers are used to with profit sharing plans. Changes often need to be made through plan amendments, and employers may need to account for funding rules, nondiscrimination testing, and, where applicable, Pension Benefit Guaranty Corporation (PBGC) coverage and premiums. That does not mean the plan lacks flexibility, but it does mean each change should be reviewed in the context of cost, compliance, and long-term business goals.

When a Cash Balance Plan May Make Sense

For certain businesses, a cash balance plan may offer another way to support retirement readiness for owners and key employees as part of a thoughtful long-term plan design. A useful starting point is often a practical conversation about goals, cash flow, workforce demographics, and how much complexity the business is prepared to take on. From there, employers can better determine whether a cash balance plan may be an appropriate addition to their retirement strategy.
