The Income Shield: Defined Benefit & Cash Balance Plans

The Income Shield: Defined Benefit & Cash Balance Plans

Too rich for a 401(k)? How business owners and high-income professionals can deduct $200k+ annually and slash their taxable income instantly.

Executive Summary

  • The Problem: Successful business owners and doctors maximize their 401(k) ($69k limit with profit sharing), but still face massive tax bills on hundreds of thousands of dollars in remaining income. A 401(k) is too small a bucket.
  • The Solution (DB Plan): Unlike a 401(k) (Defined Contribution), a Defined Benefit (DB) Plan promises a specific payout at retirement. To fund this future promise, the IRS allows you to contribute (and deduct) huge sums today ($100k – $300k+) depending on your age and income.
  • Cash Balance Plan: A modern hybrid of DB and 401(k). It creates a hypothetical account balance for each participant. It is the preferred structure for medical groups and law firms to allow partners to defer massive taxes.

The Mandatory Commitment

A 401(k) is discretionary (you can stop contributing in bad years). A DB Plan is a mandatory obligation. You must make the actuarially determined contribution every year, regardless of profit. Do not start this unless you have stable, high cash flow for 3-5 years.

“If you are paying $200k in taxes, you are effectively buying a Ferrari for the government every year. A DB Plan lets you buy that Ferrari for your own retirement instead.”
