Cash Balance Plans for Business Owners

A Cash Balance Plan is a defined benefit plan that reads like an account balance — and for the right owner it can unlock far larger deductible contributions than a 401(k) alone.

A Cash Balance Plan is a type of defined benefit plan, but it is designed to feel far more intuitive than an old-fashioned pension. Instead of expressing your benefit as a monthly income stream decades from now, it communicates a hypothetical account balance that grows each year from two sources: a pay credit (a contribution defined by the plan) and an interest credit (a guaranteed crediting rate set in the plan document).

For a profitable owner, that structure can permit much larger deductible retirement contributions than a stand-alone 401(k). It is not a fit for every company, but where it fits, the impact on deductions and retirement accumulation can be significant.

How the contributions scale with age

Because a defined benefit plan funds a target benefit by retirement age, older owners can generally support larger annual contributions than younger owners — there are simply fewer years to fund the benefit. Illustrative annual owner contribution ranges often look like this (actual figures require actuarial calculation):

• Age 40–45: roughly $80,000–$140,000
• Age 50–55: roughly $150,000–$240,000
• Age 60+: roughly $250,000–$300,000+

These are stacked on top of what a coordinated 401(k) and profit sharing plan may allow, which is why the combined design can be so powerful for the right owner.

Who tends to be a good fit

• Owners with strong, stable income who want to contribute well beyond defined contribution limits.
• Owners who are typically 40 or older and want to accelerate retirement funding.
• Businesses with employee demographics that allow the design to pass nondiscrimination testing at a reasonable staff cost.
• Owners comfortable with a recurring, expected annual funding commitment.

The tradeoffs to understand

A Cash Balance Plan is more involved than a SEP IRA or 401(k). It requires an actuary, a formal plan document, annual administration and certification, and disciplined funding. Because it is a defined benefit plan, contributions are not as discretionary as a profit sharing contribution — the plan creates a funding obligation, although designs can be built with reasonable ranges and amended over time.

How it works with your 401(k)

In most designs, the Cash Balance Plan does not replace the 401(k) — it sits alongside it. The 401(k) captures employee deferrals and a profit sharing allocation, while the Cash Balance Plan adds the larger employer-funded layer. Coordinating the two correctly is where plan design and actuarial work matter most, particularly for passing IRS testing while keeping staff contributions efficient.

Frequently Asked Questions

How much can I contribute to a Cash Balance Plan?

Contributions are actuarially determined and scale with age and compensation — often $100,000 to $300,000 or more per year for the right owner. The exact figure requires a feasibility study.

Is a Cash Balance Plan worth the administration cost?

For owners who can use the large deductions and sustain the funding, the tax benefit often far exceeds the administrative cost. For owners with volatile income or unfavorable demographics, it may not be the right fit.

Can I have both a 401(k) and a Cash Balance Plan?

Yes. Most high-income designs pair a coordinated 401(k) and profit sharing plan with the Cash Balance Plan to maximize total deductible contributions.
