How a Business Owner Turned a $275K Tax Liability Into a Retirement Asset

How a Business Owner Turned a $275K Tax Liability Into a Retirement Asset

At 54, running a professional services business that earns $600,000 a year, and facing a $275,000 estimated tax bill — that combination is not unusual for successful business owners in the United States. What is unusual is someone doing something about it in a structured, coordinated way before the check clears.

This is the case of a business owner who used a cash balance pension plan — coordinated between a financial advisor and a CPA — to convert a substantial tax liability into a retirement asset. And then did it again the next year, and the year after that.

The Client: 54 Years Old, $600K Income, Under $500K in Retirement Savings

The owner ran a professional services S-corp. Revenue was solid and consistent — $600,000 per year in taxable income. The business was mature, well-managed, and generating predictable cash flow.

The retirement picture told a different story. The owner had been maximizing a SEP-IRA for several years. The annual SEP-IRA limit at this income level was $70,000. Combined with earlier contributions, total liquid retirement assets were under $500,000.

For someone with five to six years until a target retirement age of 60, that number created a gap. The income was there. The wealth accumulation hadn't kept pace.

The estimated federal and state tax liability: $275,000 per year.

Bull Oak was engaged to build a financial plan that addressed both the retirement gap and the tax picture simultaneously. The first question they asked — one that the client's prior CPA had not raised — was whether a cash balance pension plan had ever been modeled.

It hadn't.

What a Cash Balance Plan Is and Why Age 54 Is the Right Time

A cash balance plan is a type of defined benefit pension plan. Unlike a 401(k) or SEP-IRA, which are defined contribution plans, a cash balance plan defines the benefit the owner will receive at retirement — and requires annual contributions to fund that benefit.

The IRS allows substantially higher annual contributions to defined benefit plans than to defined contribution plans, precisely because the plan is obligated to deliver a specific retirement benefit. For a business owner at age 54, the contribution limits approach $200,000 or more per year depending on the actuarial calculation (the exact figure is determined by an actuary and depends on age, salary, and target benefit).

This is the strategic window. The older you are, the larger the permissible annual contribution, because there are fewer years for the contributions to compound before you reach the plan's normal retirement age. A business owner who starts a cash balance plan at 54 can contribute significantly more per year than one who starts at 40.

Importantly, those contributions are fully tax-deductible. Every dollar contributed to the cash balance plan reduces the business's taxable income dollar-for-dollar.

Year One: $195,000 in Deductible Contributions

Bull Oak coordinated with the client's CPA to design the cash balance plan. The actuary established that a $195,000 annual contribution was appropriate given the client's age, salary, and retirement target.

The tax impact in year one:

Taxable income: $600,000 Cash balance contribution: $195,000 Adjusted taxable income: $405,000

At the client's combined federal and state marginal rate, reducing taxable income by $195,000 cut the annual tax bill by approximately $75,000.

The $195,000 that would have been paid partly as taxes was instead placed into a funded retirement account. The client's net out-of-pocket cost to fund $195,000 in retirement savings was approximately $120,000, after the tax savings.

That's a 38% effective discount on retirement savings, funded by the government.

Years Two and Three: Compounding the Strategy

Bull Oak's approach was not to treat the cash balance plan as a one-time move. It was integrated into a multi-year financial plan.

In years two and three, the cash balance contributions continued at the actuarially determined level. Alongside those contributions, the plan coordinated:

S-corp salary optimization. The reasonable salary paid through the S-corp was calibrated to support both the cash balance plan contribution base and the QBI deduction strategy under the OBBBA's permanent extension. These levers interact — the W-2 wage limitation on the QBI deduction at high income levels requires modeling to optimize.

QBI planning under OBBBA. With the deduction now permanent, the multi-year projection of the QBI benefit was incorporated into the long-term financial model. The planning horizon for structural decisions shifted from "before the 2025 sunset" to "for the foreseeable future."

Asset allocation for the pension. The cash balance plan's assets are invested. Bull Oak handled the investment strategy for the plan assets within the advisor's fiduciary role — separate from any tax decisions, which remained with the CPA.

Over three years, the cumulative reduction in tax liability from the combined strategy exceeded $200,000, while the retirement account balance grew substantially.

The Important Coordination Point

Bull Oak framed this as a two-professional engagement from the start. The financial planning and investment strategy for the pension assets was handled by Bull Oak in their capacity as financial advisors. The tax implementation — the cash balance plan contribution deduction, the QBI calculation, the S-corp salary structure — was handled by the client's CPA.

This coordination matters for legal and regulatory reasons. A financial advisor who is not also a licensed CPA does not provide tax advice. A CPA who is not a licensed investment advisor does not manage the pension assets. The client had both, working from the same plan.

If you're a business owner considering a cash balance plan and your CPA and financial advisor have never spoken to each other, that's the first thing to fix.

What This Strategy Requires

A cash balance plan is not the right tool for every business owner. It makes the most sense when:

You have consistent income over $250,000 per year and can commit to annual contributions. Cash balance plans have required minimum contributions — you can't skip a year because revenue was down.

You're within 10-15 years of your target retirement age. The contribution limits are highest and the strategy is most powerful in this window.

You have a CPA who can coordinate the plan design with an actuary and manage the tax treatment. The contribution deduction needs to be documented correctly.

For the client in this case, all three conditions were met. The result was a retirement savings acceleration that wouldn't have happened without the coordinated plan — and a tax liability that shrank materially in the years the strategy ran.

If you're a business owner over 50 with consistent income above $250,000 and you're still relying solely on a SEP-IRA or 401(k), a cash balance plan may be worth modeling. The most reviewed financial advisors on Sam's List who work with business owners understand how this coordination works.
