Cash Balance Plans Explained for Business Owners

A cash balance plan is a type of defined benefit plan that expresses each participant's benefit as a hypothetical account balance. The account is credited each year with a pay credit and an interest credit, and at retirement the participant receives the balance as a lump sum or converts it to an annuity. The legal structure is still a defined benefit plan, so funding rules, actuarial certification, and coverage requirements apply.

How the Account Works

Each participant has a notional account, not a separate investment account. The plan document defines the annual pay credit, often a flat dollar amount or a percentage of pay, and the interest credit, which may be a fixed rate or tied to an index. The account balance grows according to those formulas, regardless of how the underlying plan assets perform. The employer is responsible for funding the promised balance, so investment outperformance or underperformance shifts cost to the employer.

How This Differs from a Traditional Defined Benefit Plan

A traditional plan typically promises an annuity based on years of service and salary. A cash balance plan communicates the benefit as a lump sum, which employees may find easier to understand. For owners, cash balance plans are often designed to allow relatively large annual pay credits, especially at older ages, while still satisfying nondiscrimination rules. Because the benefit is portable as a lump sum, it can be rolled into an IRA upon termination or retirement.

Why Owners Consider Them

Owners typically explore a cash balance plan when:

• They want to contribute more than 401(k) and profit sharing limits allow.
• They are established and expect stable profits for several years.
• They want the ability to define the pay credit for each participant group in a way that meets testing rules.
• They value clarity about the target account balance.

Design Choices

Design flexibility is a major reason for their popularity. The plan can set different pay credit formulas for different groups, subject to nondiscrimination testing. The interest crediting rate can be fixed, which stabilizes the projected liability, or variable. Choices about the crediting rate can influence how much investment risk the employer bears. A conservative investment strategy is often chosen to match the crediting rate.

Employees and Testing

Employees who meet eligibility requirements generally must be covered, and the plan must pass coverage and nondiscrimination tests. Employers commonly pair the cash balance plan with a 401(k) profit sharing plan to satisfy testing and to give employees a base contribution. The cost of employee benefits can be significant compared with the owner's contribution, so modeling the total plan cost is essential.

Funding and Flexibility

Because required contributions are determined by an actuary, the company must be able to fund the plan each year. Some plans include design features that allow adjustments, such as freezing pay credits or amending the plan, but there are restrictions on changes that reduce accrued benefits. Termination requires specific steps and typically involves final funding and distribution of assets.

Costs

Costs include actuarial fees, administration, a plan document, and annual filings. These are generally higher than for a solo 401(k) or SEP. When considering whether the potential tax deferral is worth the cost, compare the total fees and the required funding against the expected benefit. Owners should also consider that contributions are deferral, not permanent elimination of tax, as distributions are generally taxable when received.

A Hypothetical Illustration

Imagine a business owner in her fifties who wants to accelerate savings. An actuary designs a cash balance plan with a pay credit for the owner and a smaller credit for a handful of employees, along with a fixed interest credit. The owner reviews the total cost, including required contributions and fees, and concludes the plan is affordable in a typical year. She elects to proceed. The example is hypothetical and no specific contribution level is implied.

Exit and Rollover

At retirement or termination, participants can generally roll their balances into an IRA, which preserves tax deferral. Owners should plan the timing of any lump sum distributions and coordinate with the overall tax picture, because distributions can be taxable in a single year if not rolled over.

Questions to Ask

1. What annual contribution range is likely and what drives it?
2. How are employees covered and what does that cost?
3. What interest crediting rate is proposed and why?
4. What is the plan's exit process?

Comparing Illustrations Fairly

When you receive plan illustrations from more than one provider, compare them on the same assumptions. Look at the pay credit, the interest crediting rate, the projected required contribution, the employee cost, and the annual fee. A design that looks attractive because it uses an aggressive assumption may not hold up if conditions change. Ask each provider to show a downside scenario, and prefer designs you could still fund if profit dropped.

A Word on Documentation

Keep the plan document, annual valuation reports, and funding notices together. Those records support the deduction and make it easier to transition to a new advisor or administrator if needed.
