The Cash Balance Plan: How High Earners Can Shield $300k+ Annually from Taxes

COACHING POINTS

  • The Limit Breaker: While 401(k) plans are capped at ~$69,000 (2025), Cash Balance Plans allow for contributions exceeding $300,000 per year, depending on your age and income. It is the only way to compress 20 years of saving into 5 years.
  • The Tax Arbitrage: Every dollar contributed reduces your taxable income dollar-for-dollar. For a high earner in the 37% bracket + state tax, a $300k contribution creates an immediate tax savings of ~$120,000+.
  • The Asset Protection: Like other ERISA-qualified plans, assets in a Cash Balance Plan are generally protected from creditors and lawsuits, adding a layer of legal safety to the tax benefits.

If you are a successful business owner or partner earning over $500k, the 401(k) limit is a nuisance. You are likely paying more in taxes than you are saving for retirement. The Cash Balance Plan fixes this. It is a “Defined Benefit” plan that looks and feels like a 401(k) but has the contribution limits of a corporate pension.

The Age-Weighted Math

Defined Benefit limits are based on providing a specific payout at retirement. The closer you are to retirement, the more you can put in.

  • Annual Benefit Limit: $275,000 (Max annuity payout at age 62). Authority: IRS COLA Limits 2025
  • Lump Sum Max: ~$3.5 Million (The pot needed to fund that annuity).
  • Example (Age 60): To reach that $3.5M pot by age 62, you might need to contribute $300,000+ per year. This entire amount is tax-deductible.

What-If Scenario: 55-Year-Old Doctor ($800k Income)

Goal: Maximize Tax Deferral. Tax Rate: 40% (Fed + State).

Strategy Total Contribution Tax Savings (@40%) Take-Home Impact
401(k) + Profit Sharing $76,500 (Max) $30,600 Baseline
+ Cash Balance Plan $76,500 + $223,500 $120,000 Cost is offset by tax savings
Result: By adding the Cash Balance Plan, the doctor shelters an extra $223,500 and saves an additional ~$90,000 in cash taxes this year.

Execution Protocol

1
Hire an Actuary
You cannot open this at Fidelity with a click. It requires a Third-Party Administrator (TPA) and an Actuary to calculate your specific limits annually based on age and income. Authority: IRS Pub 560
2
Check “Owner-Only” Status
This strategy is most efficient for Solopreneurs or partnerships with few employees. If you have many staff, you must contribute to them too (typically 5-7.5% of their salary) to pass non-discrimination testing.
3
Commit for 3-5 Years
This is a “Pension” plan. You must intend to keep it open for at least a few years. It is not a one-year tax hack. However, you can freeze or terminate it later if business profits decline.

COACHING DIRECTIVE

  • Do This: If you are over 45, self-employed (or partner), earn >$400k, and want to catch up on retirement savings aggressively.
  • Avoid This: If your income fluctuates wildly. The contribution is mandatory. A bad year could force you to terminate the plan early, inviting IRS scrutiny.

Frequently Asked Questions

What is a Cash Balance Plan?

It is a type of ‘Defined Benefit’ pension plan that acts like a ‘Defined Contribution’ plan (401k). The employer credits a participant’s account with a set percentage of their yearly compensation plus a fixed interest rate credit.

Who is the ideal candidate?

High-income business owners, partners in professional firms (doctors, lawyers), or independent contractors aged 45+ who consistently earn enough to max out a 401(k) and still have excess cash flow.

Are the contributions mandatory?

Yes. Unlike a 401(k) where you can change contributions at will, a Cash Balance Plan requires a consistent annual funding commitment. However, the plan can be amended or frozen if business conditions change drastically.

Disclaimer: Cash Balance Plans have high administrative costs ($2k-$5k/year) and strict funding requirements. Investments must be managed conservatively to meet the interest credit target. Consult an actuary.
