The cash balance plan, in plain English.
If you own a profitable practice or business and the 401(k) limit feels almost insulting against your income, there is a second pension on the menu that almost no one mentions. It can move six figures off your taxable income in a single year — and it deserves a clear, unhyped explanation.
A pension that thinks it’s a 401(k).
Qualified retirement plans come in two families: defined contribution (the 401(k) you already know, where the contribution is capped and the ending balance is whatever it grows to) and defined benefit (the old-fashioned pension, where a future benefit is promised and the contribution is whatever it takes to fund it).
A cash balance plan is a defined benefit plan wearing a 401(k)’s clothes. Legally it’s a pension, which is why the contribution limits are so much larger. But each participant has an individual hypothetical account with a stated balance that grows two ways every year: a pay credit (the employer contribution) and an interest crediting rate, or ICR (a fixed growth rate written into the plan, often around 5%). It reads like a 401(k) statement, but it funds like a pension.
The combination is the point. You get the very high contribution ceiling of a defined benefit plan with the familiar, portable, “number on a page” feel of a defined contribution plan. Pair it with a 401(k) and profit-sharing plan — the standard “combo” design — and a high-earning owner can shelter far more than either plan allows alone.
Assets now held in cash balance plans nationwide — one of the fastest-growing corners of the retirement-plan world.
How much more an owner in their mid-40s or older can typically contribute versus a standalone 401(k) — the multiple varies widely by age and income (see the table).
Of employer contributions are tax-deductible to the business in the year they’re made, and grow tax-deferred.
Industry totals are approximate, drawn from public Form 5500 / U.S. Department of Labor data (cash balance assets surpassed $1 trillion over roughly two decades of growth); figures change year to year.
The limits, when the 401(k) stops being enough.
A cash balance plan is sized so that, by your target retirement age, your hypothetical account can reach the actuarial equivalent of the maximum pension the IRS allows — a lifetime benefit of $290,000 a year for 2026, or roughly $3.5 million as a lump sum (an actuarial estimate that varies with interest rates at distribution; the $290,000 annual figure is fixed by statute for 2026). Because older owners have fewer years to get there, they’re allowed to contribute the most.
| Owner’s age | 401(k) + Profit Sharing1 | Cash Balance2 | Combined, pre-tax |
|---|---|---|---|
| 30–34 | $72,000 | $80,000 | $152,000 |
| 35–39 | $72,000 | $105,000 | $177,000 |
| 40–44 | $72,000 | $135,000 | $207,000 |
| 45–49 | $72,000 | $175,000 | $247,000 |
| 50–54 | $80,000 | $225,000 | $305,000 |
| 55–59 | $80,000 | $285,000 | $365,000 |
| 60–63 | $83,250 | $345,000 | $428,250 |
| 64–67 | $80,000 | $385,000 | $465,000 |
1. 2026 defined-contribution maximum: $72,000 in total additions (IRC §415(c)), plus the age-50 catch-up of $8,000, or the special age 60–63 catch-up of $11,250. Assumes compensation at or above the $360,000 limit.
2. Cash balance figures are illustrative approximate maximums for a sole or lead owner. Actual amounts are actuarially determined and depend on your age, compensation history, years to retirement, plan design, and the contributions required for any employees. Your numbers will differ.
A 55-year-old maxing a 401(k) shelters $80,000. A 55-year-old with a well-designed cash balance plan can shelter roughly $365,000 in the same year — an illustrative maximum for the scenario in the table above; your amount depends on your age, income, and plan design.
Six reasons it’s worth the paperwork.
A large, current-year deduction
Every dollar of employer contribution is deductible to the business this year, and compounds tax-deferred until you draw on it. For an owner in their peak-earning years, it can be one of the largest current-year business deductions available — one your CPA should weigh against your full tax picture.
Catch-up, at scale
If you spent two decades reinvesting in the business instead of your own retirement, this is how you make up for lost time — three to four times the annual limit of any other qualified plan.
Diversification away from the business
For most owners, the business is the net worth. A cash balance plan is a disciplined, tax-advantaged way to move money off the balance sheet of one closely held company and into a diversified portfolio you actually own.
Creditor protection, with limits
As an ERISA-qualified plan, assets in the plan are generally protected from most creditors under federal law — meaningful for litigation-exposed professions. Key exceptions apply (divorce/QDROs, IRS tax claims, criminal restitution), and protection shifts to state law once funds are distributed or rolled to an IRA. Ask your attorney about your situation.
A talent and retention tool
The same plan that funds your retirement provides a real, visible benefit to the employees you want to keep — a differentiator in a tight labor market.
Predictable, “number on a page” design
Unlike a traditional pension whose liability swings with interest rates, a cash balance plan grows at a stated rate. Owners and employees see a clear account balance, not an actuarial abstraction.
What it looks like for a practice owner.
A purely hypothetical scenario built to illustrate common plan-design features — not based on any actual client or actual results. Picture the founding partner of a small professional practice, age 55, with about $850,000 of practice income and three valued employees. The goal — cut this year’s tax bill, accelerate retirement, and reward long-tenured staff without overspending on benefits.
| Participant | Comp. | 401(k) + PS | Cash Balance | Total |
|---|---|---|---|---|
| Owner, age 55 | $360,000 | $80,000 | $285,000 | $365,000 |
| Associate, 38 | $115,000 | $8,625 | — | $8,625 |
| Sr. paralegal, 46 | $78,000 | $5,850 | — | $5,850 |
| Administrator, 29 | $52,000 | $3,900 | — | $3,900 |
| Totals | — | $98,375 | $285,000 | $383,375 |
Hypothetical illustration for education only — not a real client and not a projection of results for any specific business. Employee allocations shown at a 7.5% profit-sharing “gateway,” a common design for combined plans; actual allocations depend on census and nondiscrimination testing.
Of the $383,375 contributed across the whole plan, roughly $365,000 — about 95 cents of every dollar — lands in the owner’s own account. The owner’s share is deductible to the practice this year; at an assumed 40% combined federal-and-Utah marginal rate, the owner’s contribution defers on the order of $145,000 of tax, money that now compounds for the owner instead of leaving as a check to the IRS. These figures are hypothetical and specific to this scenario — your contribution limit, plan cost, and tax result will depend on your own facts, entity type, marginal rate, and IRS limits that change yearly. Don’t treat them as an estimate of your own savings.
The employee contributions aren’t a cost to apologize for — they’re a genuine benefit to the people who keep the practice running, and they’re what makes the owner’s large allocation pass IRS nondiscrimination testing. A well-designed plan keeps that employee cost efficient while maximizing what flows to the owner.
Two specialists, one plan.
A cash balance plan needs two different kinds of expertise. An actuary and third-party administrator (TPA) build and run the plan. An investment fiduciary decides whether you should have one at all, and then manages the money inside it. I’m the second — and I’ll bring in the right first.
Strategy & investments
- Decide whether a cash balance plan actually fits your income, your business, and your broader plan — before anyone sells you one
- Coordinate the actuary and TPA, and pressure-test the plan design against your goals
- Build and manage the plan’s investment portfolio to track the interest crediting rate and keep funding stable
- Integrate the plan with your personal portfolio, tax picture, and eventual rollover to an IRA
- Stay a fiduciary the whole way — fee-only, no product, no commission
Design & administration
- Draft the plan document and certify the actuarial funding each year
- Run nondiscrimination testing and set each participant’s contribution range
- Prepare government filings, including the annual Form 5500
- Amend or freeze the plan as your business and demographics change
The investing job is the quiet one that matters
A cash balance plan promises to grow at its interest crediting rate — say 5% — whether the market cooperates or not. If the portfolio earns more, the surplus reduces what you have to contribute next year. If it earns less, you have to make up the shortfall out of pocket. A wild, all-equity portfolio doesn’t “win” here; it just makes your required contribution unpredictable and can force cash in at the worst possible time.
So the goal isn’t to beat the market inside the plan. It’s to track the crediting rate with as little drama as possible. That’s a real, ongoing investment-management job — and it’s exactly the discipline an independent fiduciary is built for.
Be honest about the trade.
A cash balance plan is a commitment, not a one-year tax trick. The IRS expects it to run for at least five years, contributions are largely required each year, and administration costs more than a 401(k). For the right owner, the math is overwhelming. For the wrong one, it’s a headache. The line between them is usually clear.
- Owners already maxing their 401(k) who want to put away well beyond $80,000 a year
- $250,000+ of stable, pass-through or practice income
- Professional practices — attorneys, physicians, dentists, CPAs, consultants
- An owner who is older than most of the staff
- Solo owners with no employees (an excellent, simple case)
- A business willing to commit for at least five years (the IRS “permanency” expectation)
- Lumpy or unpredictable income you can’t count on year to year
- Looking for a one-time deduction with no intent to keep funding
- A young owner with an older, higher-paid workforce
- A business that can’t comfortably absorb the required contribution in a lean year
- No appetite for the added administration and actuarial cost
The honest answers.
Do I have to contribute the same amount every year? +
Largely, yes — that’s the trade for the bigger deduction. Each year the actuary calculates a contribution range with a required minimum, a recommended amount, and a maximum. You should expect to fund it annually. If your income drops, tell your advisor and TPA early; the plan can often be amended or frozen, but you can’t simply skip a year on a whim. Designs that step down the formula after a set number of years can build in flexibility from the start.
How long do I have to keep it open? +
There’s no hard number, but the IRS “permanency” expectation is generally read as at least five years. Legitimate business reasons — a sale, a real downturn — are recognized exceptions. As a rule, the longer it runs, the more you get out of it.
Do I have to cover every employee? +
No. A cash balance plan must provide a meaningful benefit to the lesser of 40% of eligible employees or 50 people, and it’s typically paired with a 401(k)/profit-sharing plan to satisfy testing. The result is a design where the large majority of the dollars can flow to the owner while employees receive a fair, efficient benefit.
When can I get the money, and how? +
At retirement, most owners convert the balance to a lump sum and roll it into an IRA, where it keeps growing tax-deferred until they draw on it. In-service access before retirement is generally limited, usually to age 62 and up under the plan terms.
What does it cost to run? +
More than a 401(k) — a cash balance plan needs annual actuarial work, so administration often runs roughly double a 401(k)’s. Set against a six-figure deduction, the cost is usually small in proportion, but it’s a real reason the plan only makes sense above a certain income.
What’s the deadline to set one up? +
The plan document can generally be adopted up to your business’s tax-filing deadline, including extensions, for the prior year. But watch the funding deadline: for a defined benefit / cash balance plan, the first year’s required contribution must usually be deposited by 8½ months after the plan year ends (about September 15 for a calendar-year plan) — earlier than the October extended return deadline. Designing the plan and funding year one takes weeks, so start the conversation well before your filing date, ideally during the plan year itself, not the week of.
