Cash Balance Plans for Physicians and Business Owners

The basics
What Is a Cash Balance Plan and How Does It Differ From a 401(k)?
A 401(k) is a defined contribution plan: the account balance depends on what goes in and how the investments perform, and the participant carries that investment risk. A cash balance plan is a defined benefit plan with a different presentation. Each participant has a hypothetical account that is credited each year with a pay credit (often a set percentage of pay or a set dollar amount) and an interest credit at a rate the plan document specifies.
The business funds the plan with real assets, and an actuary calculates how much is needed each year to support the benefits the plan promises. If plan investments fall short of what the actuary assumed, the business may need to contribute more. If they exceed it, required contributions may be lower. Either way, the funding obligation sits with the sponsor, not the individual participant.
Because the benefit is defined by a formula and funded over a period of years, contributions for an older participant can be larger than 401(k) limits allow. That feature is why these plans come up for high earners, and it is also why they carry obligations a 401(k) does not.
Fit
Who Tends to Consider a Cash Balance Plan?
The people who tend to look at these plans usually share a few traits: high and relatively stable income, a desire to save more on a tax-advantaged basis than a 401(k) allows, and an age at which fewer years remain to fund a retirement benefit. Owners of medical practices, specialty groups, and closely held businesses are common examples. A plan may be a poor fit where income swings widely, where staff costs would be high relative to the owners' benefit, or where the business could change hands soon.
For physicians, the question often comes after the standard options are full. Our guide on what a physician may consider after maxing out a 401(k) covers the broader sequence, and our article on retirement planning for physicians who started saving late looks at where a defined benefit plan fits in a catch-up timeline. Self-employed physicians may also want to compare the solo 401(k) contribution limits before deciding whether a more involved plan is worth its complexity.
Business owners weighing a sale face an additional question: how a plan interacts with the timing and structure of an exit. Our guide to business exit planning for owners explains why decisions made years before a sale may matter.
Obligations
What Does a Cash Balance Plan Require of the Practice or Business?
A cash balance plan is a commitment, not just an account. The main requirements generally include:
- Employer sponsorship: The business adopts a written plan document and is responsible for operating the plan in line with it.
- Annual actuarial work: An actuary calculates the funding requirement each year and certifies it.
- Funding obligations: Contributions generally must fall within the range the actuary calculates, whether or not the business had a strong year.
- Employee coverage: The plan generally must cover eligible employees and satisfy nondiscrimination rules, which may mean staff receive benefits the business must fund.
- Administration and filings: Ongoing recordkeeping, annual government filings, and plan-testing carry costs, and some plans may also owe insurance premiums to the Pension Benefit Guaranty Corporation depending on their size and structure.
Not every business can carry these obligations comfortably. A year of lower revenue does not automatically reduce what the plan needs, which is why cash-flow stability is central to the decision.
Illustrative example
Illustrative Example: A Physician-Owner at Age 50
Hypothetical example for illustration only. The facts are invented, no dollar results or returns are shown, and nothing here is a projection or a recommendation.
Consider a 50-year-old physician who owns a specialty practice. The practice has had steady income for several years, the owner already contributes the maximum to the practice's 401(k) plan, and six eligible employees range from their late twenties to mid-fifties. The owner asks whether a cash balance plan could add to tax-advantaged savings.
An actuary and plan administrator would typically model several designs and show three things side by side: the contribution range for the owner, the cost of the pay credits for the six employees, and the funding the practice would be required to make each year. The owner and the practice's CPA would then weigh that cost against the practice's cash flow in a weaker year, how partner or staff changes could affect the plan, and what would happen if the owner sold or merged the practice.
In this scenario the plan may look attractive in a strong year and burdensome in a weak one. That tension, rather than any single number, is usually the real decision.
2026 limits
How Are Cash Balance Plan Contribution Limits Determined?
There is no single annual contribution number for a cash balance plan. Contributions are actuarially determined, based on the benefit the plan promises, the participant's age and pay, the plan's interest-crediting terms, and the value of plan assets. The IRS limits the benefit the plan can provide rather than the contribution in any one year.
As of October 8, 2026, the IRS states that the annual benefit for a participant under a defined benefit plan generally cannot exceed the lesser of 100% of the participant's average compensation for the highest three consecutive calendar years or $290,000 for 2026 (see the IRS page on defined benefit plan benefit limits). The same IRS cost-of-living notice sets a $72,000 limit on annual additions to a defined contribution plan such as a 401(k) with profit sharing, and a $360,000 limit on the annual compensation a plan may take into account (see IRS Notice 2025-67). These dollar amounts are adjusted for cost of living in future years.
The $290,000 figure is a ceiling on the benefit at retirement, not a statement of what a physician or owner can contribute this year. Actual contributions can be higher or lower depending on the design, and added limits may apply when a business sponsors both a defined benefit plan and a 401(k) or profit-sharing plan. A plan administrator or actuary can model the figures for a specific situation.
Trade-offs
What Are the Trade-Offs and Risks?
The same features that allow larger contributions create the main risks. Funding is generally mandatory, so a drop in income, a partner departure, or a change in staff could make a required contribution harder to meet. Employee costs may be meaningful. Setup and annual administration add expense, and a deduction today is not the same as a tax saving: pre-tax money generally is taxed when it is distributed, and large pre-tax balances may lead to sizable required minimum distributions later.
Ending or changing a plan has rules of its own. A plan that is frozen or terminated may require final funding and filings, and a business sale may require the buyer to assume the plan or the seller to wind it down. Outcomes vary by plan design, and tax results depend on individual circumstances.

What Should I Ask My CPA and Plan Administrator?
Plan design requires professionals who can advise on tax, legal, and actuarial matters. GGM Wealth Advisors does not provide tax, legal, or actuarial services, so these questions are meant to bring to a CPA, an attorney, and a plan administrator or actuary you already work with:
- What range of annual contributions would the actuary expect for each design, and what happens in a year when income is lower?
- What would the plan cost for eligible employees, and how would that change if staff or partners change?
- How would a cash balance plan interact with our current 401(k) or profit-sharing plan, including deduction and testing limits?
- What are the setup, actuarial, administration, and any insurance premium costs each year?
- What would it take to amend, freeze, or terminate the plan, and how would a sale or merger affect it?
- How would distributions be taxed, and how might the plan affect required minimum distributions in retirement?
Physicians and owners often make these decisions alongside several others. Our resources for physicians and specialists planning around high income and for business owners planning around a company and its eventual transition describe the wider planning context. We consider decisions alongside a client's CPA, attorney, and other professionals when appropriate.
Straight answers
Questions about cash balance plans
A cash balance plan is a defined benefit plan that expresses each participant's benefit as a hypothetical account balance. The balance generally grows through annual pay credits and interest credits set by the plan document. The employer funds the plan based on an actuary's calculation, and the employer, not the participant, bears the investment risk on plan assets.
The IRS limits the annual benefit under a defined benefit plan to the lesser of $290,000 or 100% of the participant's average compensation for the highest three consecutive years (2026 figures, per the IRS as of October 8, 2026). That is a limit on the benefit, not a flat cap on yearly contributions. The contribution for a given year is set by an actuary and depends on age, compensation, plan design, and plan assets.
Generally not at will. Defined benefit plans are subject to minimum funding rules, so the actuary calculates a required contribution within a range each year. A plan can sometimes be amended, frozen, or terminated, but those steps have rules, costs, and timing requirements. A plan administrator and attorney can explain what is possible for a specific plan.
Generally yes. A qualified plan must cover eligible employees and satisfy nondiscrimination and coverage rules, so staff may receive benefits and the business may bear that cost. A practice or business with no eligible employees other than the owner may have a simpler design. The specifics depend on the plan document and should be confirmed with a plan administrator.
Not usually. Many businesses that sponsor a cash balance plan also keep a 401(k) or profit-sharing plan, and the plans interact through combined deduction and testing rules. Whether pairing them makes sense depends on income stability, staff demographics, and cash flow, which is a question for a CPA and plan administrator.
