Cash Balance Plan Deduction: Feasibility, Funding and Employee Costs

By AE Tax Advisors Team · Updated November 6, 2026

A cash balance plan is a defined benefit pension plan, even though participants see an account-style benefit. Before commissioning one, ask for a census-based feasibility study that separates required funding, the deductible contribution range, employee costs and business cash needs. An age-based online estimate cannot establish your contribution.

Give the actuary the complete employer picture

• Ownership of all related businesses, including changes expected through acquisitions or succession.
• Employee dates of birth, hire dates, hours, compensation and ownership; include eligible part-time employees and related-employer staff.
• Existing retirement plans, prior benefits, plan documents and recent valuations.
• Owner compensation or self-employment income, profit forecasts, debt service and available cash after operating reserves.
• Expected retirement, business sale or ownership-change dates.

Coverage, nondiscrimination and related-employer rules determine who must benefit. Do not assume a separate management company permits an owner-only plan, or that employee cost is a standard percentage of payroll. Request participant-level costs and the assumptions behind them.

Ask for minimum funding and the deductible range separately

Required funding is not the same as the maximum tax deduction. The actuary evaluates the benefit formula, compensation, service, existing assets, prior funding and actuarial assumptions. Age is one input, not a contribution schedule. Coordinate the deductible amount with the tax preparer before transferring funds.

Compare a base forecast with lower profits, weaker asset performance, additional employees and an earlier business sale. Ask how each affects required contributions and administrative costs. A hypothetical account balance is not a separately invested personal account; the employer remains responsible for the plan's obligations. A permissible actual-return or variable crediting formula does not eliminate funding, benefit or termination risk. See the Department of Labor cash balance plan guidance.

Combining a cash balance plan with a 401(k)

The plans can coexist, but contributions, employer deductions and employee testing require coordinated calculations. Under Section 404(a)(7), the 6% threshold is an exception within combined employer deduction rules, not a universal profit-sharing contribution cap. Employer defined-contribution amounts above that threshold can enter the combined-limit calculation. Elective deferrals and PBGC-covered single-employer defined benefit plans receive specified exclusions. Other applicable limits still matter.

Have the actuary, plan administrator and tax preparer agree on the calculation for the actual plans. Do not add a maximum 401(k) figure to an age-based pension estimate and call the sum deductible.

Confirm PBGC coverage rather than choosing it

The professional-service exemption requires a plan that has never covered more than 25 active participants since ERISA's enactment, established and maintained by an employer whose principal business is professional services and owned or controlled by professional individuals engaged in that same service. A small employee count alone is insufficient. Other exemptions have their own conditions. Obtain a coverage determination when uncertain; see PBGC coverage guidance.

Adoption, funding and deduction dates differ

A permissible prior-year adoption deadline does not automatically extend minimum funding deadlines. Defined benefit minimum funding generally has a final deadline 8½ months after plan-year end, with quarterly installments where applicable. Deduction timing, plan adoption and any 401(k) deferral elections or deposits need separate calendar entries. Ask the administrator to provide the dates for your plan year and employer tax year before signing. IRS Publication 560 explains these distinct requirements.

Costs and downside decisions to put in the proposal

Budgeting estimates are $2,000 to $5,000 for setup and $2,500 to $6,000 per year for actuarial and administrative work, plus investment management. These are estimates, not a current provider quote or guaranteed total. Confirm employee funding, PBGC premiums if applicable, amendments, termination work and other exclusions separately.

A freeze can stop future accruals under the applicable amendment and notice rules, but does not erase benefits already earned or remaining funding obligations. Termination is a formal process, not an automatic rollover when profits fall. Ask who will manage participant notices, funding, final filings and permitted distributions. See the defined benefit administration and exit checklist.

Illustrative feasibility review

An owner planning both a practice expansion and a pension asks for three projections: maintaining current staffing, hiring additional employees and a lower-profit year. This illustrates a review process, not projected savings. The decision package should show owner and employee benefits, required funding, deductible range, fees, cash remaining and who updates the forecast. Proceed only after the written scope assigns design, administration, tax reporting and ongoing monitoring.
