Case Study: Why Strategic Design is Essential for Defined Benefit Plans
Defined Benefit (DB) plans—and their hybrid cousins, Cash Balance plans—are among the most powerful retirement vehicles for business owners and high-income professionals. But they require thoughtful design and ongoing strategy to deliver long-term value. Without it, even well-intentioned contributions can fall short of their full potential.
In this case study, we explore how a highly successful physician, referred to us by his CPA, nearly missed out on a million-dollar opportunity by misunderstanding how a DB plan works. It’s a powerful reminder that plan design isn’t just a technicality—it’s the engine of your wealth-building strategy.
Understanding Defined Benefit Plan Design
Defined Benefit and Cash Balance plans offer pre-tax contributions that can dramatically reduce taxable income. Unlike 401(k) plans with capped contributions, DB plans allow for six-figure annual contributions based on age, income, and years to retirement.
However, these plans are actuarially driven. Investment performance isn’t the focus—predictability and funding consistency are. That’s why strategic design is essential.
Why Defined Benefit Plans Must Be Designed Intentionally
- DB plans are contribution-first, not return-first. The real advantage is the annual tax deduction, not chasing market performance.
- Overperformance can backfire. If investments outperform targets, the required contribution can drop to zero, eliminating your deduction in future years.
Compliance and nondiscrimination testing matter. Pairing a DB or Cash Balance plan with a Safe Harbor 401(k) Profit Sharing plan helps you pass testing requirements and offer meaningful benefits to staff.
DB Dilemma: Missing the Forest for the Trees
Dr. Dan, a successful physician in California, was referred to us by his CPA to reduce his tax burden through a defined benefit plan. But like many high-earning professionals, Dr. Dan was laser-focused on investment returns.
“In the DB plan, we’re not trying to have great returns. The real return is the contribution deduction,” Mike explained.
That message didn’t land at first.
Dr. Dan insisted that his personal investments consistently outperformed 10%, and he didn’t want to “settle” for a 5–6% return target. He was ready to walk away from the plan entirely.
The Spreadsheet That Changed Everything
To bring the strategy into focus, Mike built a custom spreadsheet. The tool let Dr. Dan compare two paths:
- Taxable investing: After-tax dollars, chasing 10%+ returns.
- Tax-deferred DB contributions: Pre-tax savings with a modest 5% return.
The result? Over a 15-year projection, the defined benefit strategy outperformed by approximately $1 million.
Dr. Dan’s response:
“Well, I think the DB plan might be good for me. I need a tax deduction.”
The Real Power of a Defined Benefit Plan
What finally shifted Dr. Dan’s thinking was this realization:
“The tax deductions are like a match from the federal and state government.”
If you contribute $200,000 a year into a DB plan, you’re saving up to $100,000 a year in taxes. That’s not a theory—it’s cash in hand.
Strategic Design Supports Recruiting and Retention, Too
While Dr. Dan’s plan focused on owner savings, many high-income business owners layer a DB plan with a Safe Harbor 401(k) Profit Sharing plan. Why?
- Pass nondiscrimination testing: These combined plans meet IRS requirements for fair treatment of employees.
- Reward your team: You can offer staff meaningful retirement benefits without overextending your budget.
- Attract and retain top talent: Competitive retirement packages are a magnet for high-performing employees.
Strategy Turns Complexity Into Value
Defined Benefit and Cash Balance plans are not set-it-and-forget-it. They require expertise, actuarial insight, and a clear understanding of the tradeoffs between return, contribution, and compliance.
With strategic design, these plans can reduce tax liability, build retirement wealth, and support a healthy company culture. Without it, business owners may miss out on millions.
