Family business succession planning is a coordinated plan for who owns the business, who runs it, what it is worth, and who pays the tax. A will transfers ownership and leaves the other three unanswered.
A will can move shares to your heirs. It cannot tell a bank who signs the credit line on Monday morning. It cannot tell your daughter what her brother's 40 percent is worth, or where he finds the cash to buy her out. It cannot stop the IRS from asking for estate tax nine months after your death on a business nobody can sell that fast. Those questions live in other documents, and most owners have never written them.
What does a will actually do for a family business?
A will does one job well: it directs who receives your property when you die. For a closely held business, that means it directs who receives the shares or membership units.
That is a narrower job than most owners assume. The will says nothing about who has voting control, who becomes an officer, whether the non-active children get paid, what price applies if someone wants out, or how the family finds money to pay a tax bill on an illiquid asset. Those terms are set by the operating agreement, the shareholder agreement, the buy-sell agreement, and the funding behind them.
A will names an owner. It does not name a leader, set a price, or produce cash. Succession requires all three.
This is also why a plan can look complete on paper and still fail in practice. If you have not pressure-tested the documents against a real event, read whether your estate plan will work the way you intended before assuming the file in the attorney's office covers the business.
- Buy-sell agreement
- A contract among owners that sets who may buy an ownership interest, on what trigger events (death, disability, divorce, departure), at what price, and on what payment terms.
- Valuation formula
- The method written into the buy-sell for setting price, such as an independent appraisal on a set schedule, a multiple of earnings, or a periodically agreed value.
- Key person
- An individual whose departure would materially damage revenue, lending relationships, or operations. Often the founder, sometimes not.
- Section 6166 election
- A federal provision that may allow the executor of a qualifying estate to defer and then pay estate tax attributable to a closely held business in installments rather than all at once.
Which documents do the real work in family business succession planning?
Think of the will as one line in a larger system. Here is what each piece controls, and what tends to happen when it is missing.
| Document | What it controls | What happens without it |
|---|---|---|
| Will and revocable trust | Who receives the ownership interest | State intestacy law decides, and the interest may pass through probate as public record |
| Operating or shareholder agreement | Voting, management rights, transfer restrictions, deadlock resolution | An inheriting spouse or in-law may gain voting rights the family never intended |
| Buy-sell agreement | Trigger events, who may buy, price method, payment terms | Heirs and remaining owners negotiate under pressure, often with lawyers on both sides |
| Current valuation | The number everyone plans around | Family members argue over worth at the worst possible moment |
| Funding source | Where buyout cash and estate tax cash come from | The business borrows, sells assets, or sells itself |
| Employment and compensation agreements | Roles, pay, and expectations for family and non-family managers | Active children and inactive children fight about fairness |
Notice that only the first row is what most people mean by "estate planning." The other five rows are business governance documents that happen to have enormous estate consequences.
Who runs it versus who owns it?
This is the decision that separates plans that hold together from plans that blow up at the first family dinner after the funeral.
Ownership is an economic right. Management is a job. Many founders try to solve fairness by splitting shares equally among children, including the ones who have never worked a day in the business. That creates a company where the operator answers to siblings who do not share their risk, their hours, or their view of reinvestment.
Equal is not the same as fair. Dividing shares equally among active and inactive children solves an emotional problem and creates a governance one.
There are structural ways to separate the two: voting and non-voting interests, distinct classes of units, trusts that hold economic interest while a manager holds control, or equalizing inactive children with assets outside the business. Which one fits depends on entity type, family dynamics, and how your business is taxed. Entity structure drives more of this than owners expect, which is why the S-Corp versus LLC decision shows up in succession conversations as often as it does in tax conversations. An S corporation, for example, has limits on who may hold shares, and certain trusts must make specific elections to qualify.
Where does the money come from?
A buy-sell agreement without funding is a promise to write a check nobody has. Three cash needs tend to arrive at once.
1. The buyout itself
If the agreement requires surviving owners or the company to purchase a departing owner's interest, the cash has to exist. Common funding approaches include life insurance owned by the company or by the other owners, a sinking fund, seller financing over a term of years, or third-party debt. Each has different balance sheet, tax, and credit consequences, and the choice belongs in the plan rather than in the moment.
2. Estate tax and settlement costs
Federal estate tax returns are due within nine months after the date of death. For the 2026 tax year, the federal estate and gift tax basic exclusion amount is $15,000,000 per person, up from $13,990,000 in 2025. Many family businesses fall under that threshold and owe no federal estate tax at all. Some do not, and state estate or inheritance taxes may apply at far lower thresholds. These figures are adjusted annually, so confirm the current-year number with your tax professional before acting on it.
3. Working capital after the transition
Lenders often reassess credit facilities when the guarantor dies. Key customers and key employees test the new leadership. The company needs breathing room precisely when it is paying out cash.
The estate tax deadline does not move because the asset is illiquid. Nine months is nine months, whether or not there is a buyer.
For estates where the closely held business is the dominant asset, Section 6166 may help. If the interest in a closely held business included in the gross estate exceeds 35 percent of the adjusted gross estate, the executor may elect to defer the estate tax attributable to that interest for five years and then pay it in installments over ten years. Corporate stock generally qualifies if 20 percent or more in value of the voting stock is included in the gross estate, or the corporation had 45 or fewer shareholders. This is a technical election with ongoing conditions, and it is decided by your attorney and tax professional, not by a marketing article.
What is the business actually worth?
Every part of the plan runs on this number, and most families are working from a stale one.
A valuation set in the buy-sell five years ago may bear no relationship to today's earnings. A formula written for a company doing $4 million in revenue may produce absurd results at $12 million. Worse, a price the family agreed to informally is not a price the IRS is required to accept for estate tax purposes, and it is not a price a departing sibling's attorney will accept either.
Practical standard: put the valuation method in the buy-sell, name who performs it, and set a refresh interval. Annual or biennial is common for businesses in a growth phase. Then actually do it. A refresh schedule that everyone ignores is worse than no schedule, because it creates the appearance of a process that the record will not support.
How does family business succession planning get sequenced?
Succession is a multi-year project. Compressed timelines are where value leaks out. A workable sequence looks roughly like this.
- Years 1 to 2: visibility. Current valuation, entity and document audit, family conversation about who wants what, and an honest read on which children want to run the company versus own a piece of it.
- Years 2 to 3: structure. Update the operating or shareholder agreement, write or rewrite the buy-sell, separate voting from economic interest if needed, and align the estate documents with the business documents so they do not contradict each other.
- Years 3 to 5: funding and gifting. Put the buyout funding in place. Where transferring value during life makes sense, the annual gift tax exclusion for 2026 is $19,000 per recipient, which supports gradual transfers of minority interests over time. Larger lifetime transfers run against the basic exclusion amount and require a gift tax return.
- Years 5 to 7: handover. Move authority, not just title. Customer relationships, banking relationships, vendor relationships, and signing authority transfer in stages while the founder is still available to answer questions.
If a sale to an outside buyer is part of the picture rather than an internal transfer, the pre-transaction work is different in important ways. See estate planning for business owners before a transaction for what belongs in place first.
Where these plans usually break
Four failure patterns show up repeatedly.
The documents contradict each other. The trust says the shares go into a family trust. The shareholder agreement says shares may not be transferred to a trust without consent. Both were drafted competently, years apart, by professionals who never spoke.
The buy-sell was never funded. The agreement is signed and sitting in a drawer. The funding was going to happen "next year," for eleven years.
Nobody told the family. The plan is technically sound and completely unannounced. The first time the children learn how ownership was divided is the day it takes effect, which is the day they are least equipped to accept it.
No one is coordinating. The attorney drafts, the CPA files, the advisor manages the portfolio, and the owner is the only person holding all four corners. That is the structural problem behind most of the others, and it is fixable. Our view on coordinating your CPA, advisor, and attorney lays out how the roles fit together.
Every succession plan that failed was, at some point, a good plan that nobody kept current.
Anchor's role in this work is strategy and coordination. We do not draft legal documents or prepare tax filings. Your attorney drafts, your CPA files, and the plan is built so their work points the same direction. If you are inside a decade of stepping back, the estate planning checkpoints to review around age 60 pair naturally with this work.
Frequently asked questions
Is a will enough if my business is small?
Rarely. Size affects the tax exposure, not the governance problem. Even a business with one owner and two children needs to answer who runs it, what it is worth, and whether the inactive child gets bought out or stays a partner. A will answers none of those.
When should family business succession planning start?
Practically, three to seven years before the intended handover, because funding, valuation refreshes, and staged authority transfer all take time. Legally, the buy-sell and governance documents should exist as soon as there is more than one owner or more than one likely heir.
How do I treat children who work in the business and children who do not?
Usually by separating ownership from control, or by equalizing inactive children with assets outside the business. Splitting voting shares equally among active and inactive children tends to create governance conflict later. There is no single right answer, and the choice depends on entity type, family dynamics, and what non-business assets exist.
What happens if my heirs cannot pay the estate tax?
The estate tax return is due within nine months of death, which can force a rushed sale or borrowing. Qualifying estates where the closely held business exceeds 35 percent of the adjusted gross estate may be able to elect installment payment under Section 6166. Planning ahead for liquidity is generally preferable to relying on an election with strict conditions.
How often should the buy-sell agreement be updated?
Review it whenever ownership changes, when the valuation changes materially, when the entity structure changes, and on a set calendar regardless. Many growing companies refresh the valuation annually or every two years and review the full agreement every three.
Does a trust replace the need for a buy-sell agreement?
No. A trust governs how an interest is held and passed. A buy-sell governs the terms between owners, including price and payment. They solve different problems and need to be drafted so they do not conflict with each other.
