Maxed Out Your 401(k)? Why Silicon Valley High Earners Should Consider a Cash Balance Plan

Maxed Out Your 401(k)? Why Silicon Valley High Earners Should Consider a Cash Balance Plan

September 02, 2025

If you’re a business owner, tech executive or startup founder in the Bay Area, you might already be maxing out your 401(k) contributions every year. That’s a great start, but if you still have surplus income, there’s another retirement savings tool that could reduce your taxes and accelerate your wealth: the cash balance plan.

Here are answers to the questions we hear most often from high-income professionals in Silicon Valley.

Q: I’m already contributing the max to my 401(k). What else can I do to save for retirement and reduce my taxes?


A: If you’ve reached the IRS 401(k) contribution limit, you can add a cash balance plan alongside your existing 401(k). This is a type of defined benefit plan that allows much larger, tax-deductible contributions – often in the range of $100,000 to $300,000+ per year, depending on your age and business structure. This strategy can significantly lower your taxable income while building a substantial retirement fund.

Q: Who is a good fit for a cash balance plan?


A: We often see the best fit among:

  • Business owners with consistent, high annual income
  • Tech founders or executives nearing a liquidity event
  • Professional firms (law, medical, engineering) with small or younger staff
  • High-income couples looking to catch up on retirement savings before stepping back from work 

Q: How is a cash balance plan different from just investing in taxable accounts?

A: Taxable investment accounts offer flexibility but no immediate tax deduction. A cash balance plan lets you put away a much larger portion of your income pre-tax, growing it tax deferred. Over time, the tax savings alone can be substantial – especially for California residents facing high state and federal rates.

Q: Are there drawbacks or risks I should know about?

A: These plans require annual minimum contributions, so they work best for those with predictable cash flow. They also have administrative and compliance requirements, including an actuary to calculate funding levels. That’s why working with an advisor who understands both the tax and investment side is critical.

Q: Can I have both a 401(k) and a cash balance plan?

A: Yes – and this is where the biggest opportunities exist. Stacking a 401(k) and a cash balance plan can allow high six-figure annual contributions, dramatically accelerating retirement savings while reducing taxable income.

Q: How do I set up a cash balance plan in California?

A: You’ll need a coordinated team – typically a financial advisor, a third-party administrator (TPA) and your CPA. At Johanson & Yau, we specialize in building custom retirement plan strategies for tech professionals, business owners and startup founders. We design plans that align with your income, business structure and long-term goals.

Q: How can I find out if a cash balance plan makes sense for me?

A: Start with a review of your income, tax liability and existing retirement plan. From there, we can model how much you could contribute, the potential tax savings and how it fits into your overall financial plan.
