The $412,000 Tax Shield: How a 55-Year-Old Orthopedic Surgeon Slashed $171,000 Off His Annual Tax Bill
A real-world quantitative breakdown of pairing a Defined Benefit Cash Balance Plan with a 401(k) Profit Sharing Plan to shelter $350k+ in top-bracket earnings.
The Limits of Traditional 401(k)s for High Earners
For physicians, dental surgeons, attorneys, and successful business owners earning $400,000 to $1,000,000+ per year, the standard IRS 401(k) limit of $69,000 ($76,500 with age 50 catch-up) is grossly insufficient. At a 47% combined federal and state marginal tax rate, high earners surrender hundreds of thousands of dollars to taxes. A Cash Balance Plan bypasses standard defined contribution limits, allowing older owners to contribute an additional $200,000 to $350,000+ legally each year.
The Scenario: Dr. Robert's Surgical Practice
Dr. Robert (Age 55) operates an orthopedic surgical practice with $500,000 in net profit. He employs 2 medical assistants with a combined W-2 payroll of $80,000. He compares keeping a standard 401(k) vs. establishing a Cash Balance Combo Plan:
Max Shelter: $76,500
Remaining Taxable: $423,500
Tax Bill: $202,856 / yr
Cash Balance: $289,000
401(k) Profit Share: $69,000
Total Shelter: $358,000 / yr
Staff Cost (6%): -$4,800

Frequently Asked Questions (Cash Balance Plans)
What is a Cash Balance Defined Benefit Plan?
A Cash Balance Plan is a hybrid defined benefit pension plan that defines the benefit in terms of a stated account balance rather than a monthly lifetime annuity. Under IRC § 415, high-earning business owners and partners can contribute between $100,000 and $350,000+ per year in pre-tax dollars depending on their age.
Can a Cash Balance Plan be paired with a 401(k) Profit Sharing Plan?
Yes. Pairing a Cash Balance Plan with a 401(k) Profit Sharing Plan (known as a 'Combo Plan') is the industry standard for maximum tax sheltering, allowing older business owners to shelter upwards of $400,000+ annually in combined pre-tax deductions.
Why do older business owners get higher contribution limits in a Cash Balance Plan?
Because Defined Benefit limits are calculated actuarially based on the amount of capital needed to fund a maximum allowable retirement benefit (IRC § 415 dollar limit) by retirement age (typically age 62-65). Older owners have fewer years to fund this target, resulting in significantly higher legal annual contribution limits.
