What is a cash balance plan and how much can an owner put in?

The short answer

A cash balance plan is a type of pension that a business can add next to its 401(k). Because the contribution is based on the benefit you are allowed to build by retirement, an owner in their 50s or 60s can often set aside several times what a 401(k) alone allows.

For 2026, the IRS caps the annual benefit a defined benefit plan can provide at $290,000 and counts at most $360,000 of compensation. An actuary turns those limits into a contribution for your age and pay.

What is a cash balance plan, in plain terms?

Legally it is a defined benefit plan, the same family as a traditional pension. On paper it looks like a 401(k). Each participant has an account balance that grows two ways each year:

• A pay credit, often a percentage of salary or a flat dollar amount set in the plan document.
• An interest credit, a rate the plan defines, which may be fixed or tied to an index.

The difference from a 401(k) is who carries the obligation. In a 401(k), you decide what to put in and the account rises and falls with the investments. In a cash balance plan, the company promises the stated balance, so it must fund the plan each year and absorb any investment shortfall. The Department of Labor describes it as a defined benefit plan that states the promised benefit as an account balance.

Why do older owners get the biggest numbers?

The IRS limit is on the benefit, not on the deposit. To fund a large benefit by 62, there are fewer years left for a 58-year-old than for a 38-year-old, so the required deposit each year is larger. That is why the same plan can allow a modest contribution for a younger employee and a very large one for the owner.

It is also why this design shows up so often in the decade before a sale. An owner with high, stable profits and a plan to exit in five to ten years has exactly the profile the math rewards.

What are the 2026 limits that matter?

Cash balance plan vs 401(k): side by side

The two plans are often paired rather than chosen between. The 401(k) keeps flexibility, and the cash balance plan adds the large deductible layer. To see how plan dollars fit next to the value of the company itself, try the free business value calculator, and if a sale is on the horizon, the exit readiness scorecard shows what else to line up.

How much can an owner put in? A hypothetical example

Meet Mark, 55, a hypothetical example. He owns an engineering firm with eight employees, pays himself a $360,000 salary, and the business is consistently profitable. He wants to build wealth outside the company before a sale he expects in about seven years.

Here is one way his year could look with a 401(k) plus a cash balance plan. The cash balance figure is an assumption for illustration. A real number comes from an actuary and depends on age, pay, the plan formula, interest rates, and the employees in the plan.

Compare that with $32,500 from deferrals alone. In this example the combined design moves about $221,600 more into tax-deferred accounts in a single year. If Mark's top federal bracket were 37 percent, the deduction on that extra amount would lower this year's federal income tax by roughly $82,000. That tax is deferred, not erased. Withdrawals in retirement are taxed as ordinary income, so the value depends on the rate he pays later.

The employees in the plan also receive contributions, and that cost belongs in the business case. For a small firm, the employee cost is often a fraction of the owner's benefit, but it is a real annual expense and it is what keeps the plan qualified.

What are the trade-offs?

• It is a commitment. The company must make the required contribution every year. Plans can be amended, but this is not a "fund it when you feel like it" account.
• Costs are higher than a 401(k). Expect actuarial fees, annual Form 5500 filings, and possibly PBGC premiums, depending on the firm.
• Investment risk sits with the company. If the assets earn less than the plan's interest credit, the business makes up the difference.
• Profits need to be steady. A plan built for a strong year can be a burden in a weak one.
• Employees are part of the deal. Coverage and nondiscrimination testing are required, so the design must work for the whole payroll.

How does it fit into a business sale?

A cash balance plan can turn some of the years before a sale into large, deductible contributions that sit outside the business. That money is no longer tied to the value of one company, which is the core idea behind building wealth outside the business, covered in how your business becomes your retirement.

The plan also needs an exit of its own. Buyers rarely want to inherit a small company's pension, so plans are commonly terminated before or at closing, with balances rolled to IRAs. Termination takes filings and a final funding calculation, so it belongs on the calendar well before a letter of intent arrives. Your CPA, plan actuary, and deal attorney should all see the timeline.

The bottom line

A cash balance plan is a pension that reads like a 401(k). For an older owner with high, steady profits, it can allow far larger tax-deferred savings than a 401(k) alone, within 2026 limits of $290,000 in annual benefit and $360,000 of counted pay. It comes with required funding, higher costs, and employee contributions, and it needs a plan for how it ends when the business is sold.

Questions people ask next

Is a cash balance plan a 401(k)?

No. It is a defined benefit pension plan. It shows each participant a hypothetical account that grows with a pay credit and an interest credit, but the employer carries the funding obligation and the investment risk, and an actuary certifies the numbers each year.

How much can a business owner contribute to a cash balance plan in 2026?

There is no single dollar cap on the contribution. The limit is on the benefit: for 2026 the annual benefit a defined benefit plan can provide is capped at $290,000, and only the first $360,000 of compensation counts. The actuary converts that into a yearly contribution, which is larger the older the owner is.

Can I have a 401(k) and a cash balance plan at the same time?

Yes, and many owners do. The 401(k) keeps its own limits, $24,500 in deferrals for 2026 plus catch-up contributions. When both plans exist, combined deduction rules can limit the employer profit-sharing piece, so the plan actuary and your CPA test the design together.

Do I have to cover my employees?

Usually, yes. Qualified plans must pass nondiscrimination and coverage tests, so eligible employees generally receive a benefit. The design question is how to meet those tests at a cost that still makes sense for the business.

What happens to the plan when I sell the business?

A cash balance plan is often terminated before or at a sale, and the balances can typically be rolled to an IRA. Timing matters, because termination involves filings and final funding, so it belongs on the exit-planning calendar a year or more ahead.

Is a cash balance plan better than a 401(k) for a business owner?

Neither is better in general, and many owners use both. A 401(k) is flexible and inexpensive, with 2026 deferrals capped at $24,500 plus catch-up contributions. A cash balance plan requires funding every year, but for an owner in their 50s or 60s with steady profits, the actuary set contribution can be several times larger.
