What is a cash balance plan?
A defined benefit plan with a defined contribution feel
A Cash Balance Plan is a type of defined benefit pension plan governed by ERISA — but unlike a traditional pension, it presents each participant's benefit as a hypothetical individual account balance rather than a fixed monthly payment at retirement. Each year, the employer credits the participant's account with a "pay credit" (typically a percentage of compensation) and an "interest credit" (usually tied to a fixed rate or a market index such as the 30-year Treasury yield).
Because benefits are actuarially defined, the annual contribution required to fund those benefits — and thus the employer's tax deduction — can be substantially higher than what a 401(k) alone permits. For a business owner in their 50s, the combined annual deductible contribution between a Cash Balance Plan and a complementary 401(k)/profit sharing plan can regularly exceed $200,000 to $350,000 or more.
Who benefits most
Built for high earners with stable, profitable businesses
Cash Balance Plans are not a fit for every business. They shine brightest for a specific profile: the successful, established owner or professional who has maximized their 401(k), still faces a significant tax burden, and wants to rapidly accumulate retirement assets in a tax-sheltered environment.
Medical practices — especially solo or small group practices — are among the most common and effective settings for Cash Balance Plans. High W-2 or K-1 income, few or no employees in some structures, and a late start on retirement savings make the age-weighted acceleration particularly valuable.
Partners at law firms and solo practitioners often face the same profile: high income, meaningful tax exposure, and a desire to catch up on retirement savings. Equity partners may coordinate across the firm to establish a plan benefiting all senior partners at once.
S-corp, C-corp, and partnership owners with consistently strong profits are well-suited. If net income exceeds $200,000–$300,000 annually, the deduction alone can justify plan establishment costs many times over.
CPAs, financial advisers, architects, engineers, and other self-employed professionals with high pass-through income often find Cash Balance Plans among the most efficient retirement vehicles available to them.
Why age matters
Actuarial equivalence — the older you are, the larger your contribution
Cash Balance Plans are actuarially driven. The IRS §415 limit caps the annual benefit that can be paid out at retirement (currently $275,000 per year for 2025), and the actuary works backward from that limit to determine how much must be contributed today to fund that benefit by a normal retirement age (typically 62 or 65).
Because a 58-year-old has fewer years to accumulate investment returns before retirement than a 45-year-old, the required annual contribution for the older participant is much higher — sometimes dramatically so. This is what makes Cash Balance Plans uniquely compelling for owners in their 50s and early 60s who may have under-saved earlier in life. A 55-year-old business owner might contribute $150,000 or more per year to the Cash Balance Plan alone; a 62-year-old could exceed $250,000 annually.
This age-weighted structure means the plan's value is not symmetric — younger participants contribute meaningfully but not explosively, while older participants can effectively compress decades of tax-deferred savings into 10–15 years.
Key considerations & drawbacks
Understand the commitments before you proceed
A Cash Balance Plan is a legally binding, actuarially required commitment. The employer must make the actuarially determined contribution each year the plan is active. If profits drop sharply or the business hits a difficult period, the obligation remains. Plans can be amended or frozen — but not without cost, complexity, and IRS scrutiny. This plan is best suited to businesses with consistently strong, predictable earnings, not those with volatile income.
If your business has employees, coverage and non-discrimination rules apply. You will likely need to provide meaningful benefits to rank-and-file employees as well, which adds cost. The plan's economics are most favorable when the ownership group is older relative to employees, or when the business has very few non-owner employees. Plans with many younger, lower-paid employees can still work, but the cost–benefit tradeoff must be carefully modeled by an actuary.
Cash Balance Plans require an enrolled actuary (EA) and a third-party administrator (TPA) to design, certify, and administer annually. Setup and annual administration costs are meaningful — typically $2,000–$5,000 or more per year depending on plan complexity and provider. These costs are generally easily justified when contribution levels are high, but are a real consideration for smaller plans.
In nearly all cases, a Cash Balance Plan works best when paired with an existing 401(k)/profit sharing plan — and in many cases, the business should already have that foundational plan in place before adding a Cash Balance Plan. The two plans complement each other: the 401(k) handles employee-directed saving and elective deferrals, while the Cash Balance Plan provides the larger, owner-oriented defined benefit layer. Having both also allows the actuary to model the most favorable aggregate outcome for participants across both plans under IRS cross-testing rules.
Advanced strategies & plan carveouts
Beyond the basics — powerful combinations to explore
Cash Balance Plans can be combined with or enhanced by several complementary strategies and IRS-recognized plan structures, each with distinct planning benefits:
A §401(h) account is a sub-account within a defined benefit or Cash Balance Plan that allows the employer to fund retiree medical benefits on a tax-deductible basis. Contributions to the §401(h) account are excluded from the participant's income, grow tax-deferred, and can be used tax-free for qualified medical expenses in retirement — essentially functioning like a large, employer-funded Health Savings Account within the pension structure. For older business owners with high medical expense expectations in retirement, this can add another meaningful dimension of tax-free accumulation.
By pairing a Cash Balance Plan with a 401(k) that includes a profit sharing feature, sophisticated plan design under IRS cross-testing rules can allow the owner to maximize contributions at both the 401(k)/profit sharing level ($70,000 for 2025, or $77,500 with catch-up at age 50+) and the Cash Balance level simultaneously — dramatically increasing total annual tax-deferred contributions compared to any single plan structure.
Under IRS non-discrimination rules, "new comparability" plan designs allow profit sharing allocations to be heavily weighted toward owner-participants on an age-adjusted basis. Combined with a Cash Balance Plan, this structure can satisfy non-discrimination requirements while concentrating the majority of total contributions on the business owner, even in businesses with several employees.
When a business owner retires or sells the business, Cash Balance Plan balances can typically be rolled over to an IRA — allowing continued tax deferral. The transition from an active plan to a rollover IRA is a significant planning event that, managed properly, can preserve years of accumulated tax-deferred wealth. This is an area where qualified advisory guidance at the exit stage is particularly important.
