Many retirement plan conversations begin with a specific objective. How can we use Retirement Plans to help Business Owners reach their target contribution goals?
A financial advisor or CPA may approach a retirement plan consultant with a clear target for their client. Sometimes the goal is to maximize contributions within a standard 401(k) plan. In other cases, the objective is much larger, such as creating a six-figure tax deduction.
The role of retirement plan design is to determine how those contribution goals can be achieved efficiently while balancing employee benefit requirements and long-term compliance considerations.
Understanding how these plans work together helps business owners and their advisors determine which structure best supports their financial strategy.
Why Advisors Often Start With a Contribution Target
Financial advisors and CPAs frequently begin the conversation with a specific number in mind.
In some cases, the advisor is working backward from a financial plan that shows the client needs to increase retirement savings. In others, the CPA may be looking for a tax deduction that aligns with the client’s current income.
These discussions often lead to questions such as:
- What is the maximum contribution allowed under current rules?
- Can the plan support a larger deduction?
- What employee benefits are required if the owner contributes more?
The answers depend on the structure of the retirement plan and the composition of the workforce.
Understanding the 401(k) Contribution Limits
For many businesses, the first step is evaluating what can be accomplished with a standalone 401(k) plan.
Under current contribution rules, a combination of employee salary deferrals, employer matching contributions, and employer profit-sharing contributions can reach a defined annual limit under Internal Revenue Code Section 415(c).
The 401(k) Maximum Contribution
In many cases, the total maximum contribution for a business owner can reach $72,000 in 2026, depending on eligibility and plan structure.
This total can include:
- Employee salary deferrals
- Employer matching contributions
- Employer profit-sharing contributions
Business owners age 50 and older may also make catch-up contributions, which are added on top of this limit and can push their total contribution even higher.
Employee Benefit Requirements
When an owner contributes significant amounts through a 401(k) plan, certain contributions may also need to be made for eligible employees.
These contributions help ensure the plan remains compliant with nondiscrimination rules and maintains fairness between highly compensated employees and the broader workforce.
For companies with staff, these costs become an important factor in determining whether a basic 401(k) plan is sufficient or whether additional planning may be beneficial.
When Business Owners Want Larger Tax Deductions
Sometimes the standard 401(k) contribution limits are not large enough to meet a client’s goals.
A CPA may ask whether it is possible to create a deduction of $150,000, $200,000, or more for a business owner. When contribution targets reach that level, additional retirement plan structures often become part of the discussion.
This is where defined benefit plans and cash balance plans may enter the conversation.
Using Cash Balance Plans to Increase Contribution Limits
Cash balance plans are a form of defined benefit plan designed to allow higher tax-deductible contributions for business owners.
When combined with a 401(k) plan, they can significantly increase the amount an owner is able to contribute each year.
Why Cash Balance Plans Are Often Paired With a 401(k)
For businesses with employees, combining a cash balance plan with a 401(k) plan can create a more favorable balance between owner contributions and employee benefits.
This structure allows the plan design to direct a larger percentage of total contributions toward the business owner or other key employees while still meeting regulatory requirements for employee benefits.
The result can be a more tax-efficient retirement strategy.
Evaluating the Cost of Employee Contributions
While larger deductions can be attractive, the cost of providing benefits to employees must always be considered.
For example, a retirement strategy that generates a $200,000 owner contribution may not be appealing if employee contributions required to maintain compliance reach a similar amount.
Effective plan design aims to balance these factors.
In many optimized structures, a large majority of total contributions can be directed toward the owner or key employees while employee benefits remain manageable and compliant.
Designing a Retirement Plan That Matches the Goal
The most effective retirement plans begin with a clear understanding of the client’s contribution target and financial priorities.
In some cases, a simple 401(k) plan meets the objective perfectly. If the owner wants to contribute $50,000 or $60,000 per year, the complexity of adding a defined benefit plan may not provide meaningful additional value.
In other situations, where the owner wants to contribute significantly more, additional plan structures can unlock much larger deduction opportunities.
The key is aligning the design of the plan with the financial goal.
Balancing Contribution Size and Plan Complexity
Retirement plan design always involves balancing opportunity with complexity.
Defined benefit and cash balance plans offer powerful contribution potential, but they also introduce additional elements such as actuarial calculations and minimum funding requirements.
For business owners whose contribution goals fall within standard 401(k) limits, a simpler structure often provides the best solution.
For those seeking six-figure deductions, more advanced plan designs may provide the flexibility needed to reach those targets.
A Strategic Approach to Retirement Plan Design
Retirement plan consultants work closely with financial advisors and CPAs to translate contribution targets into plan designs that work for the business.
This collaboration helps ensure that retirement strategies support broader financial planning goals, tax strategies, and employee benefit considerations.
By modeling different scenarios and evaluating both contribution limits and employee costs, advisors can determine which retirement plan structure delivers the greatest overall value.
For business owners, the result is a retirement strategy built around their financial goals, their workforce, and the long-term future of the business.
