You did everything right. You built the business, you pay yourself well, and you max out every qualified plan your CPA put in front of you. And you are still writing the largest check of your year to the IRS. A cash balance plan is usually the piece that is missing.
For 2026, a 401(k) with profit sharing caps out at $72,000 — $83,250 if you are 60 to 63. On $900,000 of net income, that is a rounding error. A cash balance plan is how closely held business owners move from a $72,000 deduction to a $300,000-plus deduction, with nearly all of it earmarked for themselves and a short list of key people.
This is the how-to guide: what a cash balance plan is, exactly how the deduction lands in an S corporation, a C corporation, or a partnership, what it costs you in employee benefits, and — the part most guides skip — what to do once the plan hits its ceiling and you still have income you want to shelter.
What a Cash Balance Plan Actually Is
A cash balance plan is a defined benefit pension plan wearing a 401(k) costume.
Legally, it is a pension. The company promises a benefit, an enrolled actuary certifies the funding each year, and the contribution is a business obligation rather than an option. Practically, each participant sees a single hypothetical account balance that grows two ways:
- Pay credit — the annual contribution the plan document assigns to that person. It can be a flat dollar amount (“$225,000 to the owner”) or a percentage of pay. Owners and key people can be placed in their own benefit groups.
- Interest credit — a guaranteed crediting rate defined in the document, typically a fixed 4% to 5% or a rate tied to an index such as the 30-year Treasury.
That structure is why owners like it. Unlike a traditional pension, the benefit is stated as a balance the participant can understand, and unlike a profit sharing plan, the contribution is not capped at $72,000 per person. It is capped by age, compensation, and actuarial math — and age works in your favor.
The 2026 Cash Balance Plan Numbers
Start with the limits that frame every design (IRS Notice 2025-67):
| 2026 Limit | Amount |
|---|---|
| 401(k) elective deferral | $24,500 |
| Catch-up, age 50+ | $8,000 |
| Enhanced catch-up, ages 60–63 | $11,250 |
| Total defined contribution limit — 415(c) | $72,000 |
| Compensation limit — 401(a)(17) | $360,000 |
| Defined benefit annual benefit limit — 415(b) | $290,000 |
| Approximate maximum lifetime lump sum | ~$3.7 million |
| Highly compensated employee threshold | $160,000 |
| Key employee threshold | $235,000 |
Now the number you actually care about. Because the cash balance limit is driven by how many years remain until retirement age, the older the owner, the larger the deduction:
| Owner’s Age | Cash Balance Contribution | 401(k) + Profit Sharing | Approximate Total Deduction |
|---|---|---|---|
| 40 | ~$120,000 | $72,000 | ~$192,000 |
| 45 | ~$150,000 | $72,000 | ~$222,000 |
| 50 | ~$197,500 | $80,000 | ~$277,500 |
| 55 | ~$250,000 | $80,000 | ~$330,000 |
| 60 | ~$325,000 | $83,250 | ~$408,000 |
| 62 | ~$359,000 | $83,250 | ~$442,000 |
Illustrative only. Actual limits are determined by an enrolled actuary based on your compensation history, plan design, and assumed retirement age.
At a 40% combined federal and state rate, a 55-year-old owner deducting $330,000 keeps roughly $132,000 that would otherwise have gone to tax — every year, and the money stays in a creditor-protected trust with the owner’s name on it.
How the Cash Balance Plan Deduction Works in Your Entity
This is where most owners get bad advice. The plan is the same in every entity. Where the deduction lands is not.
S Corporation
Your contribution is calculated on your W-2 wages only — not on K-1 distributions. If you have been running a $150,000 salary and taking the rest as distributions to minimize payroll tax, you have capped your own pension before you started.
The corporation deducts the contribution as a business expense, which reduces the K-1 income flowing to your 1040. The planning point: your W-2 has to be large enough to support the benefit you want (compensation counts up to $360,000 in 2026), and it still has to be defensible as reasonable compensation. Raising salary to fund a pension is a legitimate reason — it just needs to be decided before the year runs, not after.
C Corporation
The contribution is deducted at the corporate level against the 21% rate. That makes the raw deduction less valuable per dollar than in a pass-through — but it is often the better answer anyway, because it moves money out of the corporation and into a personal retirement trust without a second layer of tax. Compare that to a dividend, which is taxed twice and deducted never. For professional corporations and owners who have been trapped by accumulated earnings, this is frequently the cleanest exit for cash.
Partnership and Multi-Member LLC
Two different mechanics run at once. Contributions made for employees are a partnership-level deduction that reduces every partner’s K-1. Contributions made for a partner are deducted by that partner personally on Schedule 1 of the 1040, based on that partner’s earned income from self-employment.
Two consequences worth understanding before you sign anything. First, the earned income calculation is circular — the deduction reduces the earned income the deduction is based on — so the ceiling is lower than a simple percentage of your K-1 suggests. Second, partners can be placed in different benefit groups with different pay credits, but the partnership agreement usually has to allocate the cost specially so one partner is not funding another partner’s pension. Fix the agreement first.
Sole Proprietor / Single-Member LLC
Same as a partner: the deduction is personal, based on Schedule C net earnings after the self-employment tax adjustment, with the same circular math.
The 199A Multiplier Most Owners Miss
If you are a pass-through owner, the qualified business income deduction — made permanent by the 2025 tax act — phases out above roughly $200,000 of taxable income single, $400,000 joint, and disappears entirely for a specified service business (medicine, law, accounting, consulting, financial services) once you clear the top of the phase-in range.
A cash balance contribution reduces taxable income. For an owner sitting just above the threshold, the contribution can pull income back down into the range and restore a 199A deduction that was otherwise lost. You get the pension deduction and you get the QBI deduction back. Run this with your CPA before year end — it is the single highest-leverage number in the analysis and it is entirely a timing decision.
What a Cash Balance Plan Costs You in Employee Benefits
Nobody gets a $300,000 deduction without covering staff. Three rules set the price:
- Minimum participation — 401(a)(26). A defined benefit plan must provide meaningful benefits to the lesser of 50 employees or 40% of eligible employees, with a floor of two participants. A one-person plan works if you are genuinely a one-person business; it does not work if you have twelve employees and want to cover only yourself.
- Cross-testing and the gateway. The cash balance plan and the 401(k) are tested together on a benefits basis. To use that testing, non-highly compensated employees generally need a minimum allocation of roughly 5% to 7.5% of pay depending on how the design is structured.
- Coverage. The plan has to benefit a nondiscriminatory cross-section of your workforce, not just the corner offices.
In practice, a well-designed combo runs about 5% to 8% of non-owner payroll — often satisfied by a 3% safe harbor you may already be paying plus a profit sharing allocation on top. The right way to evaluate it is a ratio, not a total: a design where 85 cents of every plan dollar lands on the owners and key people is working. A design where that number is 55 cents needs to be rebuilt, or replaced with a nonqualified structure that has no coverage rules at all.
The Rules You Have to Live With
- Permanence. The plan must be established with the intent to be permanent. Plan on funding it at least three to five years. A genuine business change — a sale, a downturn — supports an earlier termination.
- The contribution is a range, not a number. Each year the actuary certifies a minimum required contribution and a maximum deductible contribution. You choose within that band. That is your flexibility — the minimum is an obligation, not a suggestion.
- An actuary signs off annually, and the plan files a Form 5500 with a Schedule SB.
- Investments should track the crediting rate. Beating a 5% credit by a wide margin creates a surplus you may not be able to take out efficiently; falling short creates a funding shortfall you must make up in cash. Conservative, liability-matched portfolios are the point.
- Deadlines. A new plan can generally be adopted as late as your tax filing deadline including extensions, and funded by 8.5 months after year end. Do not confuse “can be adopted late” with “should be” — payroll and salary decisions have to be made during the year.
How to Set Up a Cash Balance Plan: Seven Steps
- Set the target. Not “how much can I put in” — how much do you need at your exit, and in what tax character? Everything else reverse engineers from that number.
- Pull the census. Date of birth, date of hire, compensation, ownership percentage, and family relationships for every employee. Design is impossible without it.
- Fix the compensation structure. S corporation W-2, partner guaranteed payments, C corporation salary. This is the step that gets skipped and the one that caps the result.
- Model two or three designs. Compare owner allocation percentage, staff cost, and after-tax cash flow — not just the headline deduction.
- Adopt and integrate. Execute the documents, restate the 401(k) if needed so the two plans test together, and set the interest crediting rate deliberately.
- Fund and invest to the liability. Match the portfolio to the crediting rate.
- Layer the nonqualified plan on top. Which is the rest of this guide.
Where the Cash Balance Plan Runs Out
A cash balance plan is an excellent tool with four hard edges:
- It has a ceiling. Roughly $3.7 million of lifetime accumulation and $290,000 of annual benefit. Once you are there, you are done.
- It cannot be selective. You cannot cover two key executives and skip the other forty employees. Qualified plan rules forbid it.
- Every dollar comes out as ordinary income, subject to required minimum distributions at a time and rate Congress chooses, not you.
- It retains nobody. A pension the government requires you to vest is not golden handcuffs.
Those four limits are precisely what nonqualified plans exist to solve.
Layer Two: Building the Nonqualified Stack on Top
Once the qualified bucket is full, the question changes from how do I get a deduction to how do I accumulate selectively, control the vesting, and create income that is not fully taxable at distribution. Four structures do that work.
The Leveraged Bonus (Section 162 / REBA)
The simplest step up from the pension. The company bonuses a premium into a life policy the executive owns; the company deducts it as compensation, the executive reports it as W-2 income. Add a gross-up — the “double bonus” — and the benefit costs the executive nothing out of pocket. Add a restrictive endorsement and it becomes a REBA: the executive cannot touch the cash value without the company’s consent until the vesting schedule you wrote is satisfied.
Why it pairs well with a cash balance plan: it is fully selective, immediately deductible, has no 409A exposure, no Top Hat filing, and no coverage testing. For a pass-through owner who has maxed the pension, this is usually the next dollar. Read the full Section 162 bonus plan breakdown.
Split Dollar
Where the largest numbers live. Under a loan-regime arrangement, the company advances premium to a policy as a series of loans; the executive owes only the imputed interest, and the company is repaid from cash value or death benefit. There is no current deduction — and no current income either, which is the trade. The economics reward scale and time, and the exit is designed at inception, not improvised later.
For an owner who has already captured the deduction through the cash balance plan, split dollar is how you deploy the after-tax dollars at institutional efficiency. See Split Dollar Architecture and the SOX, 409A and strategic loan analysis.
SERP and Employer-Paid NQDC
A supplemental executive retirement plan is a written promise to pay a defined benefit at a defined date if defined conditions are met. No contribution limits. No coverage rules — you pick the participants. Full control of the vesting schedule and the forfeiture triggers.
The trade-offs are real and should be stated plainly: the employer’s deduction is deferred until the benefit is actually paid, the promise is unsecured and sits behind general creditors, and Section 409A governs every election with penalties that are unforgiving. Informal funding with corporate owned life insurance is what makes the balance sheet work. Related: phantom stock for owners who want to share growth without sharing equity, and 401(k) mirror plans when executives want to defer their own income above the qualified limits.
Choosing the Right Layer
| Cash Balance | Leveraged Bonus / REBA | Split Dollar | SERP / NQDC | |
|---|---|---|---|---|
| Current employer deduction | Yes | Yes | No | Deferred until paid |
| Current tax to executive | No | Yes (W-2) | Imputed interest only | No |
| Contribution ceiling | 415 limits | None | None | None |
| Can you pick participants? | No | Yes | Yes | Yes (top hat) |
| Must cover staff | Yes | No | No | No |
| Creditor protected for executive | Yes | Yes | Varies | No |
| Retention / golden handcuffs | Weak | Strong with endorsement | Strong | Strongest |
| Character of retirement income | Ordinary | Potentially tax-free | Potentially tax-free | Ordinary |
The Sequence That Works
For most closely held owners between $750,000 and $5 million of income, the order is consistent:
- Max the 401(k) and safe harbor. Cheap, expected, and it feeds the combined testing.
- Add the cash balance plan and take the largest deduction the design supports.
- Use a leveraged bonus or REBA for the key employees you actually want to keep — selectively, with a vesting schedule.
- Use split dollar or a SERP for the owner’s excess capital and for the executives whose numbers are too large for anything else.
- Coordinate the whole thing with the buy-sell agreement and the succession plan, so the benefit stack and the exit plan tell the same story.
That is The Perfect Plan® approach: start at the goal, then reverse engineer the structure. Most advisors sell one product and describe the goal that fits it. When the number you need at exit is fixed, the plan becomes an engineering problem, not a sales problem.
When you get to the distribution phase, the same discipline applies to turning these balances into spendable, tax-efficient income — see Creating Income in Retirement.
