A business that took decades to build can be destroyed in months if the owner dies without a proper succession plan. Here are the 5 most common estate planning mistakes business owners make — and how to avoid them.
The five most common estate planning mistakes business owners make are: (1) no buy-sell agreement, leaving the business vulnerable to forced sale or co-ownership with strangers; (2) no succession plan, leaving the business without leadership at the owner's death; (3) no business valuation, making it impossible to plan for estate taxes; (4) no liquidity plan, forcing the estate to sell the business to pay estate taxes; and (5) no coordination between the business plan and the personal estate plan.
A business is often the largest asset in an owner's estate — and the most vulnerable. Unlike a stock portfolio, a business cannot be easily divided among heirs. Unlike real estate, a business requires active management to maintain its value. And unlike a retirement account, a business has no automatic beneficiary designation.
Mistake 1 — No Buy-Sell Agreement: A buy-sell agreement is a contract among business owners that governs what happens to an owner's interest at death, disability, or departure. Without one, a deceased owner's interest passes to their heirs — who may have no interest in or ability to run the business.
The surviving owners may find themselves in business with the deceased owner's spouse, children, or creditors.
A properly structured buy-sell agreement, funded by life insurance, ensures that the surviving owners can purchase the deceased owner's interest at a fair price — providing liquidity to the estate and continuity for the business.
Mistake 2 — No Succession Plan: Who will run the business when the owner dies or becomes incapacitated? If the answer is 'I haven't thought about it,' the business is at risk. A succession plan identifies the next generation of leadership, provides for their training and development, and establishes a timeline for the transition.
Mistake 3 — No Business Valuation: Estate taxes are based on the fair market value of the business at the owner's death. Without a current valuation, the estate may be surprised by a large tax bill — and may not have the liquidity to pay it. A current valuation also informs the buy-sell agreement price and the succession plan.
Mistake 4 — No Liquidity Plan: The federal estate tax is due nine months after death. If the largest asset in the estate is an illiquid business, the estate may be forced to sell the business at a distressed price to pay the tax. An irrevocable life insurance trust (ILIT) funded with life insurance can provide the liquidity needed to pay estate taxes without forcing a business sale.
Mistake 5 — No Coordination Between Business and Personal Plans: The business plan and the personal estate plan must work together. The buy-sell agreement must be consistent with the will and trust. The business valuation must inform the estate tax plan. The succession plan must be coordinated with the family's wealth transfer strategy.
Most business owners have a will and some life insurance — but no buy-sell agreement, no succession plan, and no coordination between their business and personal plans. The result is a business that is destroyed at death by taxes, family conflict, and lack of leadership.
A buy-sell agreement funded by life insurance must be reviewed regularly — if the business value has grown significantly, the insurance may be insufficient to fund the buyout.
A succession plan that names a family member as successor may not be the best choice for the business — the successor must have both the desire and the ability to run the business.
Estate taxes on a business interest can be paid in installments under IRC § 6166 — but the interest charges can be significant.
A business valuation for estate tax purposes may differ significantly from the price a buyer would pay — the IRS uses fair market value, which may be higher than the liquidation value.
Business succession planning is a core component of the Mini Family Office for business owners. The strategy combines a buy-sell agreement (funded by life insurance in an ILIT), a succession plan (identifying and developing the next generation of leadership), a business valuation (updated annually), and a coordinated estate plan (ensuring the business passes seamlessly to the intended heirs).
A private foundation can be a powerful tool in business succession planning. By contributing a portion of the business interest to the foundation before sale, the owner eliminates capital gains on the contributed portion and generates a charitable deduction. The foundation then becomes a permanent philanthropic legacy funded by the business's success.
Buy-Sell Agreement — governs ownership transfer at death, disability, or departure

Family Limited Partnership — holds the business interest with valuation discounts
Private Foundation — charitable giving vehicle funded by the business

View ResearchBusiness succession planning is one of the most complex and important areas of estate planning. Our pro bono assessment evaluates your business succession situation and identifies the strategies most relevant to your goals.
If you own a business, your estate plan is incomplete without a buy-sell agreement and a succession plan — period.
Get a business valuation every 3–5 years — the value of your business is the foundation of your estate tax plan.
Fund your buy-sell agreement with life insurance held in an ILIT — this provides the liquidity needed to fund the buyout without increasing your taxable estate.
Talk to your family about succession — the most important conversations about who will run the business after you are gone should happen while you are alive and healthy.
Every business owner client needs a buy-sell agreement — it is one of the most important documents in their estate plan and one of the most commonly missing.
Coordinate with the client's CPA on the business valuation — the valuation methodology used in the buy-sell agreement must be consistent with the estate tax valuation.
The ILIT is the standard vehicle for funding a buy-sell agreement — it provides the liquidity needed to fund the buyout without increasing the taxable estate.
Succession planning is a process, not a document — it requires ongoing attention and regular updates as the business and the family evolve.
