The Retirement Account Your CPA Never Mentioned: How High Earners Can Shelter $200K+ Per Year
If you're earning $300,000, $500,000, or more, and your tax strategy ends with "I maxed out my 401(k)," you're leaving an enormous amount of money on the table every single year.
A 401(k) lets you stash $23,000 in 2025 (or $30,500 if you're 50+). That's it. For someone in the 37% bracket, that saves you roughly $8,500 in federal taxes. Not nothing — but not even close to what's possible.
There's a retirement vehicle most CPAs never bring up — partly because it takes more work to set up, partly because it doesn't fit the "file once a year and disappear" model. It's called a defined benefit plan, and for the right person, it can legally shelter $150,000 to $300,000+ in taxable income every single year.
That's not a typo. Let's break it down.
What Is a Defined Benefit Plan?
A defined benefit plan is a type of qualified retirement plan — just like a 401(k) — but instead of contributing a fixed dollar amount each year, you fund it based on a promised future benefit. An actuary calculates how much you need to contribute annually to hit a target retirement income at a defined age.
Because the contributions are actuarially determined, they can be dramatically higher than what a 401(k) or SEP-IRA allows — especially for high earners over 45 who are "catching up" toward retirement.
All contributions are pre-tax, and the money inside the plan grows tax-deferred until distributions begin.
A cash balance plan is a close cousin — technically a defined benefit plan, but presented as an account balance rather than a monthly payout. Many high earners prefer the simplicity of the cash balance structure. Both work the same way for tax purposes.
The Numbers: How Much Can You Actually Shelter?
Here's where it gets real.
In 2025, a defined benefit plan can allow annual contributions up to roughly $275,000 — sometimes more depending on your age, income, and plan design. Compare that to:
| Plan Type | 2025 Max Contribution |
|---|---|
| 401(k) (employee only) | $23,000 |
| 401(k) with profit sharing | ~$70,000 |
| SEP-IRA | ~$70,000 |
| Defined Benefit Plan | $150,000–$275,000+ |
The older you are, the higher the contribution ceiling — because you have fewer working years to accumulate that promised benefit. A 55-year-old physician with strong self-employment income can sometimes fund a defined benefit plan at the maximum level on top of a 401(k) with profit sharing, potentially sheltering $300,000+ per year in total retirement contributions.
At a 37% combined federal and state marginal rate, that's $111,000 or more in real tax savings. Per year.
Who Benefits Most from a Defined Benefit Plan?
Defined benefit plans aren't for everyone — but if you check multiple boxes on this list, it's worth a serious conversation:
- Business owners and self-employed professionals with consistent, high net income (doctors, surgeons, attorneys, consultants, franchise owners)
- High-earning W-2 employees who also run a side business or professional practice — even a modest side entity may qualify
- Earners over 45 who want to accelerate retirement savings and compress a lot of tax-advantaged funding into fewer remaining working years
- People who can afford to set aside a predictable amount annually — defined benefit plans require consistent funding; they're not ideal if your income swings wildly year to year
- Real estate investors and entrepreneurs who want to build wealth while lowering their taxable income today
If you're a surgeon running your own practice, an executive with consulting income on the side, or a business owner netting $400K+ annually, this is almost certainly on the table for you — and you may never have heard of it.
What Your CPA Is Probably Missing (And Why)
This isn't meant to bash anyone. But here's the reality of how most CPA relationships work:
You send your documents in February. Your CPA files your return in March or April. Maybe they mention an extension. You get your bill. You don't hear from them until next year.
That model doesn't allow for proactive planning. And defined benefit plans require proactive planning. The plan must be established before the end of your tax year (typically December 31), funded by the tax filing deadline, and maintained by an actuary and administrator. For a CPA who's managing hundreds of clients in a compliance-first workflow, recommending and implementing a defined benefit plan means taking on significant additional coordination.
So they don't bring it up.
That's not illegal or even unethical — it's just the difference between a tax preparer and a tax strategist. One files what happened. The other shapes what's going to happen.
Year-round, proactive tax planning is what separates high earners who pay 35–40% effective tax rates from those who've engineered their situation down to 20–25% — legally, using exactly the tools the tax code was designed to offer.
Real-World Scenario: Before and After
Here's a composite example based on the kind of planning we do at Roadmap Tax. Details are anonymized.
The client: A 52-year-old orthopedic surgeon operating as an S-Corp, netting approximately $750,000 in professional income per year.
Before: Their existing strategy — a 401(k) with profit sharing maxed at roughly $70,000. Federal tax bill was pushing $220,000 per year.
After implementing a defined benefit plan stacked on top of the existing 401(k):
- Additional defined benefit plan contribution: $230,000
- Total retirement contributions: $300,000+
- Federal taxable income reduction: $230,000
- Federal tax savings (at 37%): approximately $85,000 per year
Over 10 years — before any investment growth — that's $850,000 in tax savings that stayed in the client's pocket, funding a retirement account that continued to grow tax-deferred.
Their CPA had never once mentioned a defined benefit plan.
This Is Not the Only Strategy
A defined benefit plan is one tool in a well-built tax strategy. High earners who are serious about reducing their tax burden typically layer several strategies together — entity structuring, S-Corp payroll optimization, cost segregation on real estate, charitable giving vehicles, and coordinated quarterly planning.
No one strategy does everything. But defined benefit plans are frequently the highest-dollar-impact, single move available to a business owner or self-employed professional in their 40s or 50s — and it's almost always the one their current CPA hasn't mentioned.
