Retirement Contributions Beyond 401(k) Limits

Maxing out your 401(k) is the beginning of the conversation, not the end. Several layers can extend deductible contributions well beyond the standard limits.

Once a business owner is already maxing out a 401(k), the natural next question is whether the plan design can be expanded. The answer is often yes — there are several recognized ways to contribute beyond standard 401(k) limits, each suited to a different situation. The goal is not simply the largest possible number; it is the largest contribution the business can comfortably sustain.

Start with the 401(k) ceiling

In recent years, employee 401(k) deferrals have been capped near $23,000–$23,500, with an additional catch-up for those 50 and older, and total additions (including employer contributions) capped near $70,000 per participant. For a profitable owner, that total may still be modest relative to income. Each additional layer below extends the deductible total.

Layer 1: Profit sharing

A profit sharing contribution sits on top of employee deferrals and can bring a participant toward the combined defined contribution limit. With the right allocation method (such as new comparability or age-weighted designs), profit sharing can be tilted toward owners while still passing testing — a meaningful step up from deferrals alone.

Layer 2: Cash Balance Plan

For owners who want to go well beyond the defined contribution limit, a Cash Balance Plan is the primary tool. Because it is a defined benefit plan, it can permit $100,000 to $300,000+ in additional annual deductible contributions for the right owner, scaling with age and compensation.

Layer 3: 401(h) medical reimbursement account

When retirement medical costs are part of the planning goal, a 401(h) account attached to the pension plan can add a tax-advantaged medical pool — potentially deductible going in, tax-deferred while invested, and tax-free for eligible reimbursements.

Build for sustainability

The point of layering is not to chase a headline deduction for one year. A defined benefit plan creates an expected funding obligation, so the design should reflect income you can reasonably sustain. A good plan is one you can fund through ordinary business cycles without strain — which is exactly what a feasibility review is meant to confirm.

Frequently Asked Questions

Can a business owner contribute more than the 401(k) limit?

Yes. Through profit sharing, a Cash Balance Plan, and in some cases a 401(h) account, owners may deduct contributions well beyond standard 401(k) limits, subject to age, income, demographics, and plan design.

What is the maximum a business owner can contribute across all plans?

There is no single number — it depends on age, compensation, and design. A coordinated 401(k), profit sharing, and Cash Balance Plan can reach several hundred thousand dollars per year for the right owner.

Do I need a new plan to go beyond 401(k) limits?

Usually you add layers rather than replace your 401(k). A profit sharing component and a Cash Balance Plan are commonly added alongside the existing 401(k).
