Imagine building a business from scratch with your closest friend. You spend years grinding, sacrificing weekends, and finally hitting your stride. Then, the unthinkable happens. Your partner unexpectedly passes away or suffers a severe, career-ending injury. Suddenly, you aren’t just managing the business alone—you are partners with their grieving spouse or dealing with a massive cash crunch to buy out their share. It sounds like a movie plot, but it happens to real entrepreneurs every single day.
That is where a buy-sell agreement comes in. Think of it as a prenuptial agreement for business owners. It lays out exactly who gets what, when, and for how much if someone exits the stage. But a piece of paper is only as good as the money backing it up. Without real funding, that contract is just a wish list.
What Exactly Is a Buy-Sell Agreement Anyway?
At its core, a buy-sell agreement is a legally binding contract between business co-owners. It determines what happens to a person’s shares if they die, become disabled, or just decide to retire. It prevents random outsiders—or well-meaning but inexperienced family members—from stepping in and trying to run the shop.
But here is the catch. If the agreement says you have to buy out a departing partner for two million dollars, where does that cash come from? Do you take out a massive bank loan? Do you drain your working capital and risk liquidation. That is why smart owners don’t just write the agreement; they fund it.
Why Insurance Is the Ultimate Safety Net
Funding an agreement with life insurance is often the most practical, tax-efficient route available to businesses today. When an owner passes away, the policy pays out a death benefit. This cash goes directly toward buying out the deceased partner’s shares from their heirs.
This does two major things simultaneously. First, it gives the remaining owners full control of the company without scrambling for loans. Second, it ensures the grieving family gets fair, immediate compensation. Everyone wins during an incredibly stressful time, and the business keeps running smoothly without a hitch.
The Curveball: What If an Owner Gets Disabled?
Everyone thinks about death, but what about a severe illness or injury? Statistically, a working adult is much more likely to become disabled during their career than to die young. If your partner can no longer work due to a stroke or a terrible accident, the business still needs to move forward.

This is where disability buy-out insurance enters the picture. It specifically funds the purchase of a disabled owner’s interest if they can no longer fulfill their duties. Relying on company cash flows to pay a disabled partner a full salary indefinitely while also hiring their replacement is a quick way to go bankrupt.
The Connelly Problem: A New Tax Landscape
If you haven’t looked at your business plan since the recent Connelly v. United States Supreme Court ruling, you need to do it right now. This decision completely changed the tax math for corporate-owned life insurance. Essentially, the court ruled that life insurance proceeds used to redeem shares must be included in the total value of the company for estate tax purposes.
This means your business might suddenly be worth a lot more on paper than you thought, leading to massive, unintended estate tax bills. It is a huge wake-up call for closely held businesses in 2026. Reviewing how your ownership and funding are structured is no longer optional; it is urgent.
Choosing Your Structure: Cross-Purchase vs. Entity Plans
There are two traditional ways to set up these arrangements. In an entity-purchase (or redemption) plan, the business itself buys the policies on each owner. When someone passes away, the company buys back the shares. Because of the Connelly ruling, this method now carries higher tax risks for certain wealthy business owners.
The alternative is a cross-purchase plan, where owners buy policies on each other. If there are only two or three partners, this is often the cleanest route because the insurance proceeds go directly to the individuals, bypassing the company valuation trap entirely. It can get messy with a lot of partners, but the tax benefits are hard to ignore.
Putting the Pieces Together for Your Business
Getting this right requires a solid team. You need a sharp accountant, a trusted insurance advisor, and an attorney who understands corporate law. Start by getting an accurate, professional valuation of your business so you know exactly how much coverage you actually need.
Don’t just set it and forget it, either. Your business grows, your partnership dynamics shift, and tax laws evolve. Make it a habit to review your funding strategy every single year to ensure your family and your life’s work stay fully protected.
At the end of the day, securing your business with life and disability insurance isn’t just about financial logicall maneuvers. It is about peace of mind. It is knowing that the blood, sweat, and tears you’ve poured into your enterprise won’t dissolve overnight due to an unexpected tragedy.
By taking the time to properly fund your buy-sell agreement, you protect your partners, your employees, and your own family’s wealth. It is the ultimate safety net that ensures your business legacy endures, no matter what surprises life throws your way.
