The standard 401(k) caps contributions at $23,500. A properly designed Defined Benefit plan can shelter $275,000 or more per year for a business owner in their fifties — tax-deductible, creditor-protected, and entirely legal under the Employee Retirement Income Security Act of 1974. The gap is not a secret. It is a pricing failure. The people best positioned to exploit this gap — owner-operators of profitable small businesses — are the ones least likely to have it explained to them.
Your CPA filed a return. Nobody designed a plan.
I. The default is expensive.
Most business owners inherit their retirement strategy from a payroll vendor. You received a 401(k) because your HR platform offered one. The contribution ceiling was chosen by a salesperson who never had to defend it, because it matched the previous client's ceiling — and the previous client did not complain.
This is not malice. It is the default. But defaults in the retirement industry are not neutral. They are sold by companies whose economics depend on high-volume low-customization products, and they are reviewed by professionals — CPAs, generalist advisors — whose economics depend on billable hours for what is already on the form, not original design for what is not.
The retirement industry sells products. A wealth strategist designs a plan.
The distinction is not semantic. A product is a menu item; a plan is an architecture. One is chosen; the other is designed. The difference, for a business owner earning $600,000, is approximately $250,000 per year in additional tax-deductible shelter. Multiplied across a decade of compounding, it is the difference between a retirement and a legacy.
II. What a Defined Benefit plan actually is.
A Defined Benefit plan is not a product. It is an actuarially-designed instrument that funds a target retirement benefit. Where a 401(k) asks "how much would you like to contribute this year?", a DB plan asks "what retirement benefit are we targeting, and how much must be contributed today to fund it?"
The math runs in the opposite direction. You start with the outcome; the contribution is whatever produces it. For a business owner in their fifties, that contribution routinely lands between $180,000 and $275,000 — per year, tax-deductible, governed by IRS §415(b) benefit limits and funded under rules that have been stable since ERISA was enacted in 1974.
Three Characteristics That Matter
- Tax-deductible at full face value. A $200,000 DB plan contribution reduces federal taxable income by $200,000. For a business owner in the top marginal bracket, this produces roughly $74,000 in year-one federal tax savings — before state.
- Tax-deferred compounding inside the plan. Investment gains on contributed assets are not taxed as earned. The deferral compounds on the compounding. The arithmetic is quiet — and then it is enormous.
- Creditor-protected under ERISA. Assets held in a qualified DB plan are shielded from business creditors under federal law. For owner-operators whose wealth is concentrated in an operating company, this is not a detail. It is the point.
III. The reason you have not been offered one.
DB plans are legal, elegant, and widely available. They are also inconvenient to sell. They require actuarial certification — they cannot be originated from a call-center or a payroll platform. The commission structure rewards product sales, not plan design. A financial advisor who spends a month designing a Defined Benefit plan earns a small fraction of what the same advisor earns selling a mutual fund portfolio in an afternoon.
The instrument is not secret. It is structurally under-marketed. For the small population of business owners who find out about it — usually through a CPA who happens to be curious, or an advisor who is paid to design rather than to sell — the effect on a career's worth of accumulated wealth is not marginal. It is, in almost every case I have seen, the single most valuable financial decision the owner ever made.
IV. What to do with this information.
If you are a business owner earning above $400,000 a year, and your current retirement contribution is capped at the 401(k) limit, there is a reasonable probability that a Defined Benefit plan would save you between $60,000 and $100,000 in year-one federal tax, with roughly ten times that in compounded shelter over the following decade.
Whether the strategy fits your specific circumstance depends on entity structure, employee census, compensation consistency, and retirement target. None of these require a long engagement to assess. A fifteen-minute conversation, run against your tax return and a short list of questions, is usually sufficient to produce a yes or a no.
If the answer is yes, the next step is plan design, not plan sales. If the answer is no, you have spent fifteen minutes and learned something useful about your own affairs.
Either outcome is an improvement over the default.
