What Are Defined Benefit Plans?

A Defined Benefit (DB) plan is a retirement plan that promises a specific benefit at retirement, typically based on years of service and salary. Unlike a 401(k) where your benefit depends on how much you contribute and how investments perform, a DB plan guarantees a certain retirement income regardless of market conditions.

Think of a traditional pension—that’s a Defined Benefit plan. The employer (or self-employed individual) commits to providing a specific benefit, then contributes whatever is needed to fund that promise. For high-income business owners, this creates an opportunity for massive tax-deductible contributions.

What Are Cash Balance Plans?

A Cash Balance plan is a type of Defined Benefit plan that looks and feels more like a 401(k). Instead of promising a monthly pension, it promises a hypothetical account balance that grows each year through:

At retirement, you can take the cash balance as a lump sum or convert it to an annuity. It’s the best of both worlds: DB plan contribution limits with 401(k)-style portability.

Why These Plans Are Powerful

Massive Contribution Limits

The real attraction: contribution limits far exceed 401(k)s:

The Actuarial Calculation

Contributions are determined by:

Older participants can contribute more because there’s less time for compounding.

These are rough estimates—actual amounts depend on many factors and require actuarial calculation.

How Cash Balance Plans Work

The Two Credits

Pay Credit:

Interest Credit:

Example Growth

Year 1: $50,000 pay credit Year 2: $50,000 pay credit + 5% interest on Year 1 balance Year 3: $50,000 pay credit + 5% interest on Years 1-2 balance …and so on

DB Plan vs. Cash Balance Plan

Traditional Defined Benefit

Combining with a 401(k)

The Super-Charged Strategy

The Bottom Line

Defined Benefit and Cash Balance plans offer high-income business owners and self-employed professionals the opportunity to make massive tax-deductible retirement contributions far exceeding 401(k) limits. For a 55-year-old, contributions of $250,000 or more annually may be possible—potentially saving $100,000+ in taxes each year.

The key requirements are stable, high income and willingness to commit to ongoing contributions. Unlike 401(k)s, you can’t just skip a year when cash is tight. The required contribution must be made, or penalties apply.

For the right person—a high-earning professional or business owner with stable income, few or no employees, and significant retirement catch-up goals—these plans are among the most powerful tax-saving strategies available. The combination of a 401(k) with a Cash Balance plan can shelter $300,000 or more annually from taxes.

However, the complexity, cost, and commitment required mean these plans aren’t for everyone. Careful planning, experienced advisors, and realistic assessment of your situation are essential before starting down this path.

For those who qualify, the ability to rapidly build retirement wealth while dramatically reducing current taxes makes Defined Benefit and Cash Balance plans worthy of serious consideration.

This guide provides general educational information about Defined Benefit and Cash Balance plans. These are complex retirement plans with significant actuarial, legal, and administrative requirements. Contribution limits and rules are complex and depend on many factors. Always work with qualified actuaries, ERISA attorneys, and tax professionals before implementing these plans.
