You're a successful dentist. You max out your 401(k) every year. You feel good about it.
Here's what you might not know: That $23,000 employee contribution (plus maybe employer matching) is a fraction of what you could be deferring.
With the right structure, you could be contributing $100,000, $150,000, even $275,000+ per year—all tax-deferred.
The difference compounds over 15-20 years. We're talking about millions of dollars in retirement wealth that most dentists never build.
Let me show you what you're probably missing.
The Retirement Vehicle Ladder
Think of retirement plans as a ladder. Most dentists are stuck on the first rung.
Rung 1: Basic 401(k)
Employee contribution: $23,000/year ($30,500 if 50+)
This is where most people stop. It's fine. It's better than nothing. But for a dentist earning $400,000+, it's nowhere near enough.
Rung 2: 401(k) with Profit Sharing
Total contribution: Up to $69,000/year ($76,500 if 50+)
Add employer profit-sharing contributions on top of your employee deferrals. This is better—but still leaves room for more.
Rung 3: Defined Benefit/Cash Balance Plans
Total contribution: Up to $275,000+/year (varies by age)
This is where serious wealth building happens. And this is what most dentists don't know about.
Understanding Defined Benefit Plans
A defined benefit (DB) plan promises a specific benefit at retirement—hence the name.
The contribution required to fund that promise is calculated actuarially. For older, high-income professionals, this means massive tax-deductible contributions.
The Basic Math
The older you are and the higher your income, the more you can contribute.
Why? Because you have fewer years to fund the retirement benefit. The same target benefit requires larger annual contributions when you're 55 than when you're 35.
Approximate contribution limits by age:
Age
Approx. Annual Contribution
40
$80,000 - $120,000
45
$100,000 - $150,000
50
$130,000 - $180,000
55
$170,000 - $230,000
60
$220,000 - $280,000+
These are estimates. Actual amounts depend on your specific situation, income, and plan design.
How It Works With Your Existing 401(k)
Here's the beautiful part: Defined benefit plans stack on top of 401(k)s.
You can have both:
401(k) with profit sharing: ~$69,000
Defined benefit plan: $100,000 - $200,000+
Total annual deferral: $169,000 - $275,000+
At a 37% tax bracket, that's $62,000-$100,000+ in annual tax savings.
Real Numbers: What This Looks Like
Case Study: Dr. Martinez, Age 52
Situation:
Solo practice, $480,000 net income
Maxing 401(k) at $69,000 (with profit sharing)
Taxable income after 401(k): $411,000
Current federal tax: ~$135,000
After adding defined benefit plan:
401(k) contribution: $69,000
Defined benefit contribution: $145,000
Total retirement contribution: $214,000
New taxable income: $266,000
New federal tax: ~$78,000
Annual tax savings: $57,000
But here's the real win:
Over 13 years until retirement at 65:
Additional annual contributions: $145,000
At 7% growth: ~$3.2M additional retirement assets
Tax saved along the way: ~$740,000
That's not theoretical money. That's real wealth that compounds.
Case Study: Dr. Chen, Age 48
Situation:
Group practice, 2 partners
Dr. Chen's net income: $380,000
Current 401(k): $69,000
3 employees (makes plan design important)
After optimization:
401(k) with profit sharing: $69,000
Cash balance defined benefit: $95,000
Employee contributions: ~$12,000 (required to make the math work)
Net owner benefit: $152,000
Annual tax savings: ~$35,000
Note: When you have employees, plan design becomes more complex. You may need to contribute for them too. But the math usually still works.
Cash Balance Plans: The Modern Approach
Most defined benefit plans today are "cash balance" plans rather than traditional pension-style plans.
How they work:
Each participant has a notional "account"
The account grows by a guaranteed interest rate (say, 5%)
At retirement, you receive the account balance
Why cash balance is popular:
Easier to understand (like a 401(k) with guaranteed returns)
More portable if you sell or close the practice
Cleaner to wind down if needed
For most dental practices, a cash balance plan is the right choice.
Who This Is Really For
Defined benefit plans make sense when:
✅ You're over 45 — The contributions scale with age ✅ Your income is $300,000+ — Need the income to fund contributions ✅ You have predictable income — Contributions are somewhat fixed year-to-year ✅ You have few or no employees — Fewer employee contributions required ✅ You plan to work 10+ more years — Time to compound
Defined benefit plans may NOT make sense when:
❌ You're under 40 — Contribution limits are lower; 401(k) may be enough ❌ Income is variable — Hard to commit to fixed contributions ❌ Many employees — Employee contributions can eat up the benefit ❌ Planning to exit soon — Not enough time to compound
The Employee Question
This is where it gets nuanced.
If you have employees, you typically need to contribute for them too. The IRS requires "nondiscrimination"—you can't just benefit yourself.
The math usually still works.
Example:
Your contribution: $150,000
Required employee contributions: $15,000
Net benefit to you: $135,000 (after employee costs)
Tax savings: ~$50,000
You're paying $15,000 to save $50,000. That's a good trade.
But plan design matters.
A good retirement plan administrator can structure the plan to maximize owner benefits while meeting compliance requirements. A bad one will waste your money on unnecessary employee contributions.
How to Implement
Step 1: Get the Right Analysis
You need someone who specializes in professional practice retirement planning. Not a generalist financial advisor. Not your regular CPA (unless they have this specialty).
Key questions to ask:
What's my maximum possible contribution given my age and income?
How much would we need to contribute for employees?
What's the net tax benefit after employee costs?
What are the ongoing administration costs?
Step 2: Plan Design
A retirement plan specialist (actuary) designs the plan to maximize your benefit. This involves:
Choosing the right benefit formula
Setting the interest crediting rate
Determining normal retirement age
Structuring for your specific staff situation
Step 3: Implementation
Once designed, you:
Establish the plan (legal documents)
Open plan accounts
Fund by your tax filing deadline
File required annual reports (Form 5500)
Ongoing costs:
Administration: $2,000 - $5,000/year
Actuarial valuation: $1,500 - $3,000/year
Against $40,000-$100,000 in annual tax savings, these costs are negligible.
Step 4: Annual Funding
Each year, the actuary calculates your required contribution. You fund it before your tax return deadline (including extensions).
Important: Contributions are somewhat fixed. You need to contribute roughly the same amount each year. If income drops significantly, this can be uncomfortable.
The 10-Year Comparison
Let's compare two dentists, both earning $400,000/year, both age 50.
Dentist A: 401(k) Only
Annual contribution: $69,000
Tax savings: ~$25,500/year
After 10 years at 7% growth: ~$950,000
Dentist B: 401(k) + Defined Benefit
Annual contribution: $200,000
Tax savings: ~$74,000/year
After 10 years at 7% growth: ~$2,750,000
Difference at age 60: $1,800,000
Same income. Same starting point. Different strategy.
Common Objections
"It's too complicated"
It's really not. You work with a specialist who handles the design and administration. Your involvement is: fund the account, get the tax deduction.
"I can't commit to fixed contributions"
This is a valid concern. If your income is highly variable, defined benefit plans can be uncomfortable. But for most established practices with predictable income, this isn't a problem.
"My CPA never mentioned this"
That's the whole point of this article. Most CPAs don't specialize in advanced retirement planning. They're excellent at filing returns, but they may not proactively suggest strategies like this.
"I'm too old / too young"
Too young (under 40): You're right, the numbers aren't as compelling. Focus on maxing 401(k) with profit sharing.
Too old (over 60): Actually, you're ideal. Contribution limits are highest. Even 5 years of maximum contributions can add significantly to retirement.
"What about employees?"
Employee contributions are a cost, but the math usually still works. Get a proper analysis that models your specific situation.
The Bottom Line
If you're a dentist over 45, earning $300,000+, and only doing a 401(k), you're leaving money on the table.
Not a little money. Potentially millions over your career.
The difference between $69,000/year and $200,000/year in retirement contributions is life-changing.
