One of the most common business owner retirement planning mistakes I see is owners assuming the business will fully fund retirement.
After spending decades building a successful company, it’s understandable. The business may be worth several million dollars, and the owner naturally views that value as their retirement nest egg. The problem is that many owners significantly overestimate what their business is worth, underestimate the challenges involved in selling it, or fail to account for taxes, transaction costs, and market conditions that can reduce the amount they ultimately take home.
That’s why I often encourage business owners to think about retirement planning long before the sale occurs. One of the most powerful strategies available for highly profitable businesses is combining a 401(k) with a cash balance plan during the final five to ten years before an anticipated sale.
For the right business owner, this approach can be transformative.
Don’t Let Your Entire Retirement Depend on One Asset
Business owners frequently have most of their net worth tied up in their company. While that concentration of wealth may have helped create substantial value, it can become risky as retirement approaches.
Think about it this way.
If your retirement plan depends entirely on receiving a certain amount from the sale of your business, you have a single point of failure. What if the market softens? What if a buyer values the company differently than you do? What if key employees leave? What if interest rates or economic conditions impact transaction multiples?
I’ve seen many owners who believed their business was worth $10 million only to discover the market was willing to pay $6 million or $7 million. Others find that after investment banker fees, legal fees, taxes, working capital adjustments, and other transaction costs, the amount they actually receive is far less than expected.
The best retirement plans don’t depend on one outcome.
They create multiple sources of retirement assets.
A disciplined funding strategy into a 401(k) and cash balance plan can create a significant pool of wealth outside the business, providing a valuable layer of protection and flexibility.
Why the Last Five Years Matter
The years immediately preceding a business sale are often the highest-income years of the owner’s career.
The business is mature. Profits are strong. Cash flow is predictable. Management systems are more established. In many cases, annual business income exceeds $1 million.
Those same factors that make the company attractive to buyers also create an opportunity for retirement plan funding.
A cash balance plan, when combined with a 401(k) and profit-sharing plan, allows business owners to make substantially larger tax-deductible retirement contributions than a traditional 401(k) alone. Older owners nearing retirement can often contribute hundreds of thousands of dollars annually, depending on age, compensation structure, and plan design. Cash balance plans are particularly attractive because allowable contributions generally increase as retirement approaches.
When a business owner has five years before a planned exit, those annual contributions can accumulate quickly.
Instead of hoping all retirement wealth will come from a future transaction, they begin systematically moving a portion of business profits into protected retirement assets.
The Tax Advantage Is Powerful
For owners earning more than $1 million annually, the tax benefit can be substantial.
When income reaches these levels, a significant portion is often being taxed at the highest federal marginal rate of 37%. The 37% federal bracket remains the top marginal rate in 2026.
A contribution to a cash balance plan generally creates a current-year business deduction while allowing the funds to grow tax deferred inside the retirement plan.
In simple terms, you’re moving dollars that would otherwise be taxed at one of the highest rates into a retirement account where taxation is deferred until later.
For many owners, retirement income is significantly lower than their peak earning years. As a result, distributions received years later may be taxed at lower effective rates than they would have been during the years the income was earned.
This creates a classic tax arbitrage opportunity:
- Deduct contributions while in a high tax bracket.
- Allow the investments to grow tax deferred.
- Potentially recognize the income later when personal tax rates are lower.
That is one of the reasons cash balance plans can be so effective for highly profitable business owners.
Creating Retirement Assets Outside the Business
Perhaps the biggest benefit isn’t the tax deduction.
It’s diversification.
A business owner who spends five years aggressively funding a 401(k) and cash balance plan may accumulate a retirement account balance large enough to materially change their retirement outlook.
Now the owner has:
- Retirement plan assets.
- Proceeds from the sale of the business.
- Personal investments and savings.
- Social Security benefits and other income sources.
That changes the conversation.
Instead of asking, “How much must I get for my business to retire?” the question becomes, “How much additional retirement security will the business sale provide?”
That’s a much stronger position.
The owner gains flexibility in negotiations, greater peace of mind, and reduced dependence on achieving a specific sale price.
The Hidden Benefit During Exit Planning
Many owners delay retirement planning because they believe the company itself is their retirement plan.
Ironically, those are often the owners who benefit most from a cash balance strategy.
By systematically moving wealth from the business into retirement accounts before the sale, they are converting a portion of their corporate value into personal retirement assets that are completely independent of future business performance, buyer demand, or market conditions.
The result is a more balanced retirement plan.
Rather than betting everything on a successful transaction, they are building retirement wealth while the business is still producing strong profits.
Final Thoughts
If you’re within five to ten years of selling your business and annual income exceeds $1 million, a 401(k) and cash balance plan may deserve serious consideration.
While every situation is different, I often find that owners spend more time estimating what their business might be worth than calculating what they actually need for retirement.
Those are not the same thing.
A business exit should be one component of a retirement strategy, not the entire strategy.
The owners who retire most comfortably are often those who use their final years of strong profitability to systematically build assets outside the business, maximize tax-deferred savings opportunities, and reduce their dependence on a future sale.
In many cases, that’s the difference between hoping your business funds retirement and knowing you’re already on the path to financial independence before the transaction ever occurs.
