A fixed credit is a promise. A volatile year is not an excuse.

Consulting income does not arrive like a salary. A contract slips, a retainer renews, a single client is half the year, and then the client is gone. Owners who live with that pattern are often attracted to a cash balance plan for a sensible reason. A good year produces more taxable income than a 401(k) can absorb, and a defined benefit credit can move real money into a deductible retirement promise. The attraction becomes a problem when the document freezes last year's good fortune into this year's formula. A pay credit is not a hope. Once the formula has accrued it, the sponsor owes the funding that goes with it. You do not get to skip the deposit because the pipeline thinned out, and you do not get to call the skip a business judgment.

This briefing is for that consultant: one owner, or a small group, with income that is real and uneven. It is not an argument against a plan. It is an argument against the wrong promise. The right design admits, in the document and in the funding conversation, that next year may not look like this year. Sterling Pension Group is a West Hartford third-party administrator. We coordinate independent Enrolled Actuaries for the valuation. We are not an actuarial firm. We will not write a flattering credit and leave the lean year for someone else to explain.

What the credit actually is

In a cash balance plan, each participant has a hypothetical account. The pay credit is the amount added for the year under the formula. It might be a flat dollar amount, a percentage of compensation, or an amount that differs by person. The interest credit is the growth the document applies to the account. Participants see a statement that looks a little like a 401(k) statement. The resemblance is cosmetic. The assets are pooled in a trust. The sponsor is responsible for funding the promise. If the investments earn less than the crediting rate, the sponsor makes up the difference over time. If a pay credit was accrued, the sponsor does not erase it by having a quiet fourth quarter.

A fixed dollar credit is the clearest version of the promise and the most dangerous one for uneven income. "Each year, $150,000" is easy to explain in a year when net profit is $700,000. It is the same sentence in a year when net profit is $90,000. The plan does not contain a clause, unless you wrote one, that says the credit appears only when the owner feels prosperous. Some formulas are written as a percentage of pay, which moves when pay moves. That is softer, and it is still a promise: if you take the compensation, you accrue the percentage. And for an S corporation, pay means wages, not the distribution. A consultant who keeps W-2 wages steady in order to support the formula has recreated a fixed credit by another name.

The figures in the last paragraph are illustrative. They are not IRS limits and not a recommendation of either size. The limits that are actually in force for 2025 are published in IR-2024-285 and on the IRS cost-of-living adjustment page. Elective deferrals in a 401(k), if you also have one, are capped at $23,500. The catch-up is $7,500, or $11,250 for a participant who attains age 60, 61, 62, or 63, and the higher catch-up replaces the lower one. Annual additions other than catch-up are capped at $70,000. Compensation taken into account is capped at $350,000. The defined benefit dollar limit is an annual benefit of $280,000, not a deposit, and the IRS summarizes the reductions for early payment and short service on its benefit limits page. A consultant can be well under every one of those ceilings and still be unable to fund the credit the document just promised. The ceilings are not a feasibility study.

Why "we will decide in December" is not a design

Owners often ask for a large credit with a private understanding that they will fund it only in good years. The understanding is not in the plan. Accruals follow the document. Reducing or stopping them requires an amendment adopted in time, and a significant reduction in future accruals generally requires a notice under ERISA section 204(h) before the reduction takes effect. You cannot adopt that amendment in concept. You adopt it in a signed document, on a date that is early enough to matter. A conversation with the administrator in November does not unwind a credit that accrued in January.

Freezing the plan is a real choice. It stops future accruals. It does not cancel benefits already accrued, and it does not excuse the minimum contribution those accrued benefits require. Terminating a plan is a larger project, with its own funding, filing, and timing rules, and it is a poor emergency exit from a single soft quarter. The designs that fit uneven income are the ones that were allowed to be smaller, or conditional in a way the statute actually permits, before the soft quarter arrived. When a plan is not a fit is a more useful page than a heroic contribution in a bad year.

There is a difference between a discretionary profit-sharing contribution and a pension credit. Profit-sharing, inside a defined contribution plan, can often be decided late, including after the year is over, subject to the document and to the deduction rules. That flexibility is why consultants like profit-sharing. It is also why the deduction is smaller. A cash balance credit buys a larger deduction by giving up that flexibility. You do not get both the size and the option to skip. Publication 560 draws the line between the plan types in plain IRS language. It is worth reading before you ask a pension to behave like a profit-sharing plan.

Minimum funding makes the line concrete. For a calendar-year defined benefit plan, the minimum required contribution for a year is generally due by September 15 of the following year. Some plans also owe quarterly installments. The Enrolled Actuary, not a rule of thumb, determines which schedule applies. Miss the minimum and the sponsor owes an excise tax of 10 percent of the unpaid amount, reported on Form 5330. If the shortfall is not corrected, an additional and much larger tax can apply. The 10 percent is not a financing charge you should plan to pay. It is a penalty for a funding failure.

The deduction is a different calendar. Under section 404(a)(6), a contribution is often deductible for the prior tax year if it is paid by the due date of that year's return, including extensions, and it is on account of that year. Confirm the application with your CPA. For many consultants the extended date is September 15 or October 15, depending on whether the taxpayer is a corporation, a partnership, or a sole proprietor. Those dates can land on the funding deadline or after it. Landing on the same day does not make them the same rule. A sole proprietor who may deduct a contribution as late as the extended individual return can still have owed the minimum funding deposit on September 15. And an extension you did not file does not create a later deduction date. If the return was filed in the spring, the window under 404(a)(6) is already shut.

What a consultant can honestly promise

Start with a credit the lean year can survive, not a credit the peak year can celebrate. The peak year can sometimes support an amendment that increases the credit, if the increase is adopted before it accrues and the testing still works. Increasing a formula you can afford is an ordinary amendment. Decreasing one you cannot afford is an amendment with a deadline you may already have missed. Direction matters.

Compensation design is part of the promise. A consultant who is a sole proprietor has earned income that moves with the Schedule C. The contribution moves with it, within the formula. A consultant who is an S corporation shareholder has wages that move only when payroll moves. Holding the W-2 flat so that a percentage credit stays large is a choice to keep the promise large. It may be the right choice. It should be made on purpose, with the CPA, and not discovered when the actuary asks for the payroll register.

A floor credit plus a discretionary piece is sometimes discussed and rarely as available as the phrase suggests. Defined benefit accruals have to be definitely determinable. You cannot leave the credit to a December mood and still have a pension formula. Whatever flexibility exists has to be written in a way the document, the regulations, and the Enrolled Actuary will accept. If someone offers you "total flexibility" and a large deduction in the same sentence, ask to see the sentence in the document. If it is not there, you have a sales claim.

Staff and related employers tighten the promise further. A consultant with employees cannot size the credit as if the plan were owner-only. Coverage and nondiscrimination apply. A spouse on the payroll, a child on a summer wage, or a second entity that shares control can change who must be included. The consultant overview starts from the owner. The census decides whether that description is true.

Interest credits compound the risk. A fixed crediting rate, which is the pattern in most micro plans, keeps the account statement steady and leaves the investment result with the sponsor. A market-rate credit moves the account with an index or with the assets and can make next year's contribution swing even when pay does not. Neither choice removes the pay credit. Both should be chosen by someone who has seen a bad year, not only a model of a good one. The illustration page is the right place to look at a range. A single number from a peak-year sketch is not a range.

The 401(k), if there is one, is the flexible layer. You can defer from wages as they are paid, up to $23,500, plus the catch-up if you qualify, and you can decide a profit-sharing contribution later if the document says the contribution is discretionary. Annual additions still stop at $70,000 before catch-up. That layer will not replace a cash balance plan in a peak year. It will keep you from forcing the peak-year pension formula to do a job the profit-sharing plan was built to do. The deadline calendar is where the two deposits, which feel like one check, are kept apart.

A bad year is a reason to call early

If 2025 is already softer than the year the credit was based on, the useful act is a call now, in April, not a silence until the funding date. The questions are narrow. Has the credit for 2025 already accrued. Can the formula be amended before further accruals, and is a 204(h) notice required. What minimum will the actuary sign if nothing changes. What compensation is now realistic. None of those questions is answered by skipping a deposit and hoping the administrator will "true it up."

Sterling Pension Group can administer the amendment, the notice, the census, and the filing calendar. The independent Enrolled Actuary certifies the funding numbers. Your CPA decides what is deductible and on which return. We will not advise you to ignore a minimum because the business had a difficult quarter. That advice would be wrong, and it would not be ours to give. This briefing is not tax, legal, or actuarial advice.

What to do in the next two weeks

Put last year's net income, this year's year-to-date income, and a deliberately pessimistic year-end estimate on one page. Use the compensation the plan can see, not billings. If you are an S corporation, use wages.

If you do not yet have a plan, ask for an illustration at the pessimistic compensation, and a second illustration at a number you have actually earned in a weak year, not only in a strong one. Tell the person preparing it that the credit has to be survivable. Reject any sketch that assumes you will "just not fund it" if the year disappoints.

If you already have a plan, read the pay credit formula and write the accrual date in the margin. If the formula is larger than the pessimistic page can fund, contact us before you contact anyone about skipping the deposit. Skipping is not one of the options. Amending, reducing future accruals in time, or freezing may be. Which of those is still open depends on the document and on the date, and two weeks is enough time to find out.
