401(k), Profit Sharing or Defined Benefit Plan? What Business Owners Should Compare
The largest possible contribution is not necessarily the best starting point for choosing a company retirement plan.
By William M. LaPiana, CEPA® | President, Paxton Financial Services
For a profitable business owner, retirement-plan design can become an important part of both personal planning and employee benefits.
But 401(k) plans, profit-sharing contributions, and defined benefit plans work differently.
The question is not simply:
“Which plan lets me contribute the most?”
A more useful question is:
“Which structure fits the business well enough to maintain over time?”
Start With the 401(k)
A 401(k) allows eligible employees to defer compensation into the plan.
For 2026, the employee elective-deferral limit for most 401(k) plans is $24,500.
Eligible participants age 50 and older may generally contribute an additional $8,000, while certain participants ages 60 through 63 may have a higher $11,250 catch-up limit.
Employers may also make matching or other employer contributions.
A 401(k) can provide significant flexibility, but plan design, testing, employee participation, administration, and employer obligations all need consideration.
Where Profit Sharing Fits
Despite the name, a profit-sharing contribution does not simply mean distributing company profits to employees.
It is an employer retirement-plan contribution made according to the plan's design and applicable rules.
Profit-sharing provisions may provide employers with more flexibility over annual employer contributions than some other arrangements, although contribution allocations remain subject to plan terms and regulatory requirements.
For 2026, the general defined-contribution annual-additions limit is $72,000 per participant before applicable catch-up contributions, subject to compensation and other limitations.
That number should not automatically be treated as an amount every owner can contribute.
The actual contribution depends on the plan and the participant's circumstances.
A Defined Benefit Plan Works Differently
A defined benefit plan is not simply a larger 401(k).
Instead of defining the amount contributed to an individual account, the plan generally defines a retirement benefit according to a formula.
Required contributions can depend on actuarial calculations, participant ages, compensation, plan provisions, investment assumptions, and other factors.
For 2026, the IRS annual benefit limit for a defined benefit plan is generally $290,000, subject to applicable rules.
Importantly, that is a benefit limit, not a simple annual contribution limit.
Contributions required to fund the plan may vary.
That distinction matters.
Higher Potential Funding Can Mean Greater Commitment
Defined benefit plans can be relevant for certain established, profitable businesses, particularly when an owner is seeking to accelerate retirement funding.
But the potential for larger contributions comes with additional considerations.
A business may need to evaluate:
Consistency of future cash flow
Employee demographics
Owner and employee compensation
Expected years until retirement
Funding obligations
Actuarial requirements
Administrative costs
Investment risk
The owner's willingness to maintain the plan
A strategy that appears attractive in a particularly profitable year may feel different if business conditions change.
Compare the Plan With the Business
Retirement planning should not be separated from business planning.
Before changing or establishing a plan, consider:
How predictable are company profits?
How many employees may need to participate?
How important is annual contribution flexibility?
How much cash does the business need for operations and growth?
What retirement resources does the owner already have?
How long does the owner expect to remain involved in the company?
The answers may be more important than selecting the plan with the largest theoretical contribution.
Build Around the Longer-Term Objective
At Paxton Financial Services, business-owner retirement planning begins with understanding the business, the owner's existing assets, and the financial life the owner is working toward.
Retirement-plan design should then be evaluated with the appropriate plan administrator, actuary, CPA, and other professionals.
