Is a Cash Balance Plan Right for Your Business?

You’ve maxed out your 401(k). 

You’ve added profit sharing contributions. 

And yet, when you look at your tax bill, you’re still writing a check to the IRS that feels like a significant portion of your annual productivity.

Traditional retirement vehicles have a ceiling. In 2026, a profit sharing 401(k) plan can provide annual contributions of up to $72,000, increasing to $80,000 for participants age 50 and older and $83,250 for those ages 60-63 that are eligible for enhanced catch-up contributions. For a physician, attorney, or accounting firm partner earning $1 million or more, that contribution barely moves the needle on taxable income.

Cash balance plans help break through that ceiling. Eligible business owners can contribute $100,000 to $350,000 or more annually in tax-deductible retirement savings — well beyond what a 401(k) allows. In this article, I’ll explain how cash balance plans work, who they’re best suited for, and the key considerations before setting one up.

What Is a Cash Balance Plan?

A cash balance plan is a type of defined benefit retirement plan, but it looks and feels more like a defined contribution plan to participants. 

In a 401(k) (a defined contribution plan), you can contribute up to the annual limit, invest based on your personal goals and risk tolerance, and your final balance depends on market performance. You bear the investment risk. In a traditional pension plan, the employer promises a specific monthly benefit at retirement based on years of service and salary — the employer bears the investment risk, but the benefit is expressed as future income instead of a current balance.

A cash balance plan lies between these two. Like a pension, it’s a defined benefit plan through which the employer bears investment risk. But like a 401(k), each participant has an individual account (called a hypothetical account) that shows a specific balance.

How Cash Balance Plans Work

Each year, the employer makes two types of credits to each participant’s hypothetical account:

• Pay credits: A set contribution, typically expressed as a percentage of compensation. If the plan specifies a 5% pay credit and an employee earns $100,000, their account receives a $5,000 credit that year.
• Interest credits: A guaranteed rate applied to the existing account balance, which is either a fixed rate or one indexed to a benchmark like the 30-year Treasury rate. This is guaranteed regardless of actual investment performance, which is why the employer bears the investment risk.

At retirement, participants can typically take their accumulated balance as a lump-sum distribution or convert it to an annuity providing monthly income. 

Cash balance plan balances can typically be rolled over to an IRA or another qualified plan if a participant leaves before retirement. This portability makes them more attractive to employees than old-style pensions and reduces the friction of workforce changes.

Tax Advantages of a Cash Balance Plan

Employer contributions to a cash balance plan are tax-deductible as a business expense, reducing current-year taxable income. Growth inside the plan is tax-deferred, so interest credits and investment returns compound without annual tax drag. And because cash balance plans can be layered on top of an existing profit sharing 401(k) plan, business owners can maximize their tax sheltered contributions while allowing employees to continue deferring from their own compensation.

For a business owner in the 37% federal marginal tax bracket contributing $200,000 annually to a cash balance plan, that’s potentially $74,000 in federal tax deferral alone, before accounting for state income taxes.

How Cash Balance Plans Compare to 401(k)s

The defining advantage is high contribution limits. While a 401(k) combined with profit sharing caps at $72,000 to $83,250 annually (as of 2026), cash balance plan contributions are age-based and actuarially determined. In turn, they can be substantially higher, particularly for owners in their 50s and 60s who have fewer years until retirement.

The IRS limits the maximum annual benefit payable from a defined benefit plan (including cash balance plans) to $290,000 under Section 415(b) for 2026, with a lifetime lump-sum accumulation cap of approximately $3.7 million. 

Annual contributions depend on the participant’s age, compensation, and years remaining until retirement. For instance, a 60-year-old may need to contribute $250,000 or more annually to reach that benefit level, while a 45-year-old would contribute significantly less given more time for compounding.

Combined with a profit sharing 401(k) plan, tax deductible contributions can reach $300,000 or more for owners in their late 50s and early 60s.

Who Cash Balance Plans Work Best For

Cash balance plans aren’t appropriate for every business. The strongest candidates share several characteristics.

Business owners 50 and older with a short runway before retirement typically benefit most. Contribution limits are substantially higher for older owners, and the combination of higher contributions and compounding over 5–15 years can help accumulate material retirement savings. 

Partners at professional service firms are among the most common users — law firms, medical practices, accounting firms, and consulting practices. These businesses typically have high partner compensation, relatively stable cash flow, and owner-heavy demographics where the math of covering employees works favorably relative to the partners’ tax savings.

Businesses with consistent, predictable cash flow. Unlike profit sharing plans, which have discretionary contributions year to year, cash balance plans require annual funding. Variable or unpredictable income can make this obligation difficult to manage.

High earners who’ve exhausted other options. If you’re already maximizing a profit sharing 401(k) plan and still have significant taxable income, a cash balance plan could be an effective next step.

An Example

A 57-year-old physician in a private practice earns $650,000 annually. She’s currently maximizing her 401(k) — $32,500 in employee deferrals and catch-up contributions plus $47,500 in employer contributions, totaling $80,000. Her practice adds a cash balance plan, allowing approximately $230,000 in additional annual tax-deductible contributions based on her age and compensation.

At her effective combined federal and state marginal rate of approximately 48% (37% federal and 11.3% California), that’s roughly $107,000 in tax deferrals. 

The Employee Coverage Requirement

Cash balance plans are qualified plans under ERISA and the Internal Revenue Code, which means they can’t solely benefit business owners. They must cover eligible employees, and employer contributions must be made on behalf of eligible staff.

Non-discrimination testing requires that the plan not disproportionately favor highly compensated employees, but this doesn’t translate to equal contributions for everyone. Plan mechanics like a new comparability formula are specifically designed to account for differences in age, compensation, and years until retirement. These allow older, higher-compensated owners to receive larger contributions based on actuarial variables not taken into account with the basic pro-rata and flat dollar methods.

Managing employee costs comes down to plan design: contribution formulas, vesting schedules, and eligibility requirements all affect what employees receive and when. The plan sponsor and plan administrator work together to structure contributions that meet compliance requirements and align with the business’s financial goals.

When Cash Balance Plans Don’t Make Sense

Cash balance plans are not ideal for every business.

• Variable or unpredictable income. If business revenue fluctuates significantly year to year, the mandatory annual funding obligation can lead to financial risk. A bad year doesn’t eliminate the contribution requirement.
• Younger business owners. Contribution limits are substantially lower for owners under 45. A profit sharing 401(k) plan may be sufficient and less expensive to administer.
• High employee turnover. Frequent workforce changes increase administrative complexity and can affect non-discrimination testing results.
• Short time horizons. If you’re planning to sell the business or retire within two to three years, setup costs and administrative burden likely outweigh the tax benefits.
• Small contribution budgets. If cash flow constraints limit contributions, annual actuarial fees, PBGC premiums, and administrative costs may not be justified by tax savings.

Is a Cash Balance Plan Right for Your Business?

Cash balance plans are a compelling tool for the right business owner — but “right” depends on age, income stability, time horizon, employee demographics, and how the plan fits alongside your existing retirement vehicles. The tax savings can be substantial. So can the administrative and funding obligations.

At BEW, we help business owners work through that evaluation, partnering with plan administrators to model contribution scenarios, analyzing employee coverage costs, and providing ongoing fiduciary oversight if a plan makes sense. If you’re a high earner who’s exhausted traditional options, it’s worth exploring.
