Selling a business to a family member

Selling a business to your son, your daughter, your sibling or your nephew is a commercial transaction wearing family clothes, and it goes wrong when one of those two things is allowed to swallow the other. The price has to be a number you could defend to a stranger, because the people it has to survive are not strangers — and the money almost never arrives as cash, which means you are usually being paid, over years, out of profits the business has not yet earned. That is the same arithmetic as a management buyout, with one extra risk on top: if the payments stop, you do not send a solicitor’s letter to a stranger. You sit opposite them at Christmas.

What this page does not cover, and why that matters first

Most of what is written about selling a business to a family member is about tax. That is not an accident: the tax and estate questions really are the largest single part of this decision, and they can change the net result by more than the price negotiation does. They are also the part where getting it wrong is expensive and difficult to reverse.

So, plainly, once: nothing on this page is about tax, reliefs, inheritance or estate planning, and nothing here should be treated as legal or financial advice. Those questions belong with your own accountant and your own solicitor, engaged before anything is agreed — not after a price has been shaken on across a kitchen table, because by then you have made a decision you may not be able to unmake. Get them in the room early. That is the whole of the advice this page offers on the subject.

What is left when you take tax out is the part almost nobody writes about properly, and it is the part that decides whether the arrangement holds together: the commercial and the practical. What the business is actually worth. Where the money comes from when the buyer is 31 and has a mortgage. What you are living on if most of the price is being paid to you in instalments. What the other children think. What happens if the person you sold it to discovers, two years in, that they do not want it.

Why a family sale is structurally different

Three things separate this from a sale to a trade buyer or an outside investor, and they compound each other:

• There is no competitive tension. In an open sale, price is discovered by more than one party wanting the thing. Here there is exactly one buyer, and they were always going to be the buyer. Nobody is bidding against anybody, so the price has to come from somewhere other than the market.
• Neither side can walk away cleanly. A trade buyer who does not like your numbers stops returning calls and you both move on. A family buyer who does not like your numbers is still your child. That asymmetry pushes both sides towards agreeing quickly and vaguely, which is exactly the wrong instinct.
• The consequences outlive the deal. Every other sale ends. This one becomes the background to the next twenty years of family life, including for the people who are not party to it.

None of that is a reason not to do it. Businesses pass within families constantly and many of them do very well, for the simple reason that the buyer already understands the business, already knows the customers, and is not going to strip it for parts. The advantages are real. They are just not a substitute for doing the arithmetic.

The rest of this page is that arithmetic, in the order it actually has to be done: the number, the funding, the fairness, the failure case, and the handover.

Why the price has to come from outside the family

The instinct in a family sale is to start from what the buyer can afford and call that the price. It is a generous instinct and it causes most of the trouble, because it produces a number that nobody can explain afterwards. An unexplained number is the one that gets re-litigated — by the buyer when trading is hard, by the seller when it is going well, and by the siblings at some point regardless.

An independently worked valuation is not there to extract the last pound from your own child. It is there so that everyone in the family, including the people not at the table, can see where the figure came from. It protects the buyer as much as the seller: a child who paid a defensible price owns the business outright in every sense, and never has to hear that it was handed to them. That protection is worth more to them than a discount.

Get to a range before anyone says a number out loud

Small businesses are usually valued by applying a multiple to a measure of profit, adjusted for the specific circumstances of the business — customer concentration, how much of the trade depends on the owner personally, the quality of the records, whether the earnings are recurring or won again every month. The mechanics are worked through in full in how to value a small business, and the free business valuation calculator will give you a range from your own figures in your browser, privately, before the subject is ever raised.

Do that privately and early. The moment you raise the possibility with a family member, the relationship has changed whether or not a sale ever happens — they now know you are planning to leave, and they now have a stake in the number. Arriving at that conversation with a worked range, rather than discovering the number during it, is the single most useful thing you can do.

Separate the value from the price, and write both down

These are two different figures and conflating them is where fairness problems start. The value is what the business is worth on a defensible, independently worked basis. The price is what you have decided to accept from this particular buyer. You are entitled to set the price below the value. It is your business. But the moment you do, the difference between the two becomes a real transfer of family wealth to one person, and pretending otherwise does not make it invisible — it only makes it undiscussed.

Family discount = independently assessed value − agreed family price

Write both numbers down, and write the discount down as its own line. A family that can point at a piece of paper saying the business was assessed at one figure, sold at another, and here is the difference and here is why, has removed almost all of the fuel from the argument before it starts. A family that only ever discussed the price has left the difference to be estimated later, by people who were not there, in a worse mood.

Why a third party is worth paying for

There is a strong argument for having the assessment done by somebody who is not in the family and is not going to benefit from the answer, even though it costs money. Not because your own arithmetic is wrong, but because it is yours. An assessment commissioned and produced entirely by the seller carries the seller’s fingerprints, and a buyer who feels the number was handed down rather than arrived at will remember that. The same applies in reverse if the buyer produces it.

This is the one respect in which a family sale should be run more formally than an arm’s-length one, not less. Outside buyers bring their own advisers and their own scepticism by default. Inside a family, that scepticism has to be deliberately imported, because nobody wants to be the person who introduced it.

How a family buyer actually pays for it

Almost no family buyer has the purchase price. They usually have a deposit made of savings, and after that the money has to come from somewhere that does not exist yet: the future profits of the business they are buying. This is the identical problem a management team faces, and the management buyout guide works the funding sources through from the buying side. The sources available in a family sale are the same, with different weightings:

Notice what that table means for you specifically. In a family sale the seller is typically funding the largest part of the purchase themselves, by waiting. You are not just the vendor; you are the principal lender, on an unsecured basis, to a borrower you cannot realistically pursue.

The year-one test

Before agreeing anything, work out what the business has to find in the first year and hold it against what the business actually earns. Everything else is detail.

Year-one headroom = operating profit − loan capital − loan interest − deferred instalment to the seller

Take an illustrative business making £180,000 a year in operating profit, after paying a market-rate salary for the owner’s job — which matters, because the family buyer has to live on something too. Agreed at an illustrative 4× multiple, the price is £720,000, funded like this:

Now the first year, at those terms:

Headroom of £2,800 on £180,000 of profit is 1.6% — and that is before tax, before any equipment the business needs to replace, and before anything at all goes wrong. It is not a deal. It is a hope.

Then run it 10% below plan, because that is the year that decides everything

Businesses have ordinary bad years. A large customer leaves, a contract slips, a supplier puts prices up. At £162,000 of profit, 10% below plan, against the same £177,200 of commitments, the business is £15,200 short.

Ask who absorbs that shortfall. The bank does not: the loan is documented, secured, and possibly secured on the buyer’s house. The instalment that gets missed is yours. In a family sale the deferred payment is the softest line in the structure, which means it is the line that flexes first — and if you have retired on the assumption of £125,000 a year for four years, the thing that flexes is your income.

This is the sentence worth sitting with: in most family sales, the seller’s retirement income and the buyer’s business are the same pot of money for several years after completion. Not two arrangements. One.

The same price, paid over longer, is a completely different deal

The price is not the lever most worth pulling. The schedule is. Keep everything identical and stretch the deferred element from four years to eight:

Same business, same price, same buyer. One version breaks in an ordinary bad year and one absorbs it comfortably. Nothing changed except time.

But read the other side of it honestly, because the trade is real. The eight-year version asks you to wait twice as long, and to keep depending on a business you no longer control for twice as long. Your exposure has not gone away; it has been swapped from a sharp risk to a long one. Which of those you prefer depends on your age, what else you have to live on, and how confident you are in the person taking over — and that is a judgement, not a calculation. The calculation only tells you what you are choosing between.

Fairness between siblings when only one is buying

For a great many families the business is the largest thing they own. When one child buys it and the others do not, the question of what is fair arrives whether or not anybody raises it — and the families that handle it worst are almost always the ones that decided it was too awkward to discuss.

Again, and only once more: how and when anything is transferred within a family, and what it costs, is a question for your solicitor and your accountant. What follows is purely the arithmetic of what a discount actually does, which is a different thing and one you can work out yourself in ten minutes.

A worked example: three children, one business

Illustrative figures throughout. A family with three adult children. One of them, call her the buyer, takes the business. The other two do not. The parents intend to treat all three equally.

• The business is independently assessed at £720,000.
• The parents agree a family price of £540,000, in effect a £180,000 discount.
• The parents hold £360,000 of other assets outside the business.

So the total the parents are distributing, counting the discount as what it is, is £540,000 of sale proceeds plus £360,000 of other assets plus the £180,000 already given away in the price: £1,080,000. An equal third of that is £360,000 each. Here is what each child ends up with under the two ways of counting:

The left-hand version treats the £180,000 discount as part of what the buyer received, so the buyer takes £180,000 in cash rather than £300,000 and all three land on £360,000. The right-hand version splits the cash equally and the buyer is £180,000 ahead — a 60% premium over each sibling (£480,000 against £300,000). Both are defensible choices. Only one of them is what most parents think they are doing when they split the cash three ways and call it equal.

Three things the table does not capture

The arithmetic is the easy half. The harder half is that neither column is obviously right:

• The buyer is not receiving £720,000 of anything. They are taking on a business, a debt, and years of work, and an illiquid asset they cannot spend. A sibling receiving £300,000 in cash has something materially easier to hold than a sibling holding a company valued at £720,000 on paper. Treating them as identical units of value is arithmetically tidy and emotionally unpersuasive.
• The value may already be partly theirs. If the buying child has worked in the business for fifteen years on below-market pay and a share of the current profit is visibly their doing, part of that £720,000 was built by the person buying it. Families rarely have a clean way to account for this, and it is one of the most common sources of quiet resentment in both directions.
• The risk is not shared. If the business halves in value over five years, the buyer carries that alone. If it doubles, the buyer keeps that alone. The siblings took their cash and went. Whether that asymmetry feels fair depends almost entirely on what happens after the deal, which is unknowable when you are deciding.

There is no formula that resolves this, and anyone selling you one is selling you a formula. What resolves it, as far as anything does, is that the numbers were visible and the reasoning was stated while the parents were alive and able to explain it. A decision the family disagrees with but understands survives. A decision the family has to reconstruct from bank statements does not.

Practically, that means having the conversation with all the children in it, once, with the assessed value, the agreed price and the difference written down in front of everybody. It is an uncomfortable hour. It is considerably less uncomfortable than the alternative version, which takes place later and without you.

What if they do not want it, or cannot run it

This is the possibility family sellers plan for least and should plan for most, because both failure modes are common and neither is anyone’s fault.

They do not want it, but will not say so

A child who has been raised around a business, whose parent has spent thirty years building it, and who is being offered it on favourable terms, is in an extremely difficult position if the honest answer is no. Declining feels like rejecting the parent, not the business. So the answer is often a yes that is really a maybe, and it holds until the first genuinely hard year.

The way to find out is to make declining cheap and early. That means:

• Ask the question separately from the offer. "Would you want to run this?" is a different question from "Will you buy it?", and it has to be asked first, on a different day, with no numbers attached.
• Say explicitly that no is an acceptable answer, and mean it. If your plan visibly collapses on a no, you have not asked a question. You have applied pressure.
• Have a real alternative in view before you ask. If you already know what you would do instead, they can hear that a no is survivable. The exit options guide sets out what the alternatives actually are, and it is worth having read it before the conversation rather than after.
• Let them work somewhere else first, if there is time. A few years outside is the most reliable test of whether the interest is genuine or inherited, and it usually improves the business either way.

They want it, but cannot run it

Wanting it and being able to do it are different, and enthusiasm is not evidence. The uncomfortable truth is that the current owner is often the worst judge of this, in both directions — too harsh because they remember the person at seventeen, or too soft because they want the story to work.

Test it before the sale, not after, and test it in the only way that produces evidence: hand over real responsibility with real consequences while you are still there. Give them the customer relationships you personally hold and see whether those customers stay. Give them a full budget cycle to own. Take a genuine month away — not a holiday where you answer the phone — and look at what the business did without you. If the business has already run for a month without the current owner, both sides know something they did not know before, and a lender will find that far more persuasive than any assurance.

Build the failure case into the paperwork

The commercial reason for engaging a solicitor early is not the completion documents. It is this: a family sale that goes wrong with nothing written down is the worst of all worlds, because there is neither a legal position nor a family one. Decide, in advance and in writing, what happens if:

• An instalment is missed — is it deferred, is interest added, does it accumulate, and at what point does something else happen?
• The buyer wants to sell the business on within a few years, to someone outside the family, while still owing you part of the price.
• The buyer becomes ill, or divorces, or dies, with the price part-paid.
• The buyer decides after two years that they do not want it after all. Can they hand it back? At what value? Do you have to take it back?

Every one of those is an ordinary contractual question with a standard answer, and every one of them is a catastrophe if it arrives undefined. Writing them down is not distrust. It is the opposite — it is the thing that lets both of you stop privately worrying about them. Families that documented the failure cases are the ones that never have to think about them again.

And be honest with yourself about your position on the downside. If the deferred payments are your retirement income, ask what you would genuinely do if they stopped. Most sellers, asked that directly, admit they would not enforce. That is a legitimate answer — but if it is your answer, then the deferred element is not really part of the price. It is a hope, and you should size it as one and make sure you can live on the part that is not.

The handover, and why leaving properly matters more here

In any sale the departing owner has to leave. In a family sale they frequently do not, and this is the single most common practical failure of the whole arrangement. It is worth being precise about why it matters more here than anywhere else.

A trade buyer has bought the business and has no relationship with you beyond the contract. When the agreed handover period ends, you go, because there is no mechanism by which you could stay. A family buyer has no such mechanism either — but they also cannot ask you to leave. They can ask their business partner to step back. They cannot easily ask their parent to.

So the departure has to be designed by the seller, in advance, and honoured by the seller. Nobody else in the arrangement is able to enforce it.

What a designed handover looks like

The commercial reason, not the emotional one

The case for leaving properly is not about dignity or letting go. It is arithmetic, and it points straight back at the year-one table earlier on this page.

If most of the price is deferred, then the profits of the next four or eight years are the money that pays you. Those profits depend on the business functioning without you. Every month you remain as the real decision-maker is a month in which the business has not yet demonstrated that it can — and the demonstration is what you are being paid out of. A seller who lingers is not protecting their investment. They are postponing the only test that matters, while the clock on their own instalments runs.

The same logic applies to what you take with you. If you personally hold the key customer relationships, the technical knowledge, the supplier terms or the pricing judgement, then the earnings that repay you can walk out of the door with you at the point you finally go. In a sale to an outsider that risk is priced into the multiple and discounted. In a family sale it is usually not discussed at all — which does not make it smaller, only later. Transferring those relationships deliberately, by name, with dates, while you are still there, is the most valuable work of the entire handover period and the part most often skipped.

The order that works

1. Value it privately first. Get a defensible range from your own figures before anybody in the family knows you are thinking about it.
2. Ask whether they want it, with no numbers in the room. Separately, and in a way that makes no a real option.
3. Test whether the business runs without you. A genuine month away. If it does not, that is the work, and no deal structure fixes it.
4. Model the year-one headroom, then model it again at 10% below plan. If the second version breaks, change the schedule before you change the price.
5. Engage an accountant and a solicitor before anything is agreed. The tax and estate questions are the largest part of this decision and they are not on this page for good reason.
6. Have the family conversation with the numbers written down — assessed value, agreed price, the difference, and what the other children receive.
7. Write down the failure cases, then agree the handover and its end date, and go on that date.

Seven steps, and the first six all happen before a single pound changes hands. That is the correct proportion. The transaction is the short part; everything that determines whether it worked happens either side of it.

Arithmetic and general information only — not financial, tax, legal or investment advice. Your own figures, and your own accountant, decide what any of this means for you.

Frequently asked questions

Can I sell my business to a family member below market value?

Commercially, yes. It is your business and you can agree any price with the buyer. What the price does not do is disappear: the difference between an independently assessed value and the price you accept is a real transfer of family wealth to one person, and it is visible to everyone else in the family. It can also have tax and estate consequences that are well outside the scope of this page. That combination is exactly why an accountant and a solicitor should be engaged before you agree a number rather than after.

How do you value a business when selling it to a family member?

The same way as for any other sale: a multiple applied to a measure of profit, adjusted for the circumstances of the business. The difference is that there is no competing buyer to discover a price, so the number has to come from an independently worked assessment instead. Having that assessment done by someone with no stake in the answer protects the buyer as much as the seller, and it gives the rest of the family something they can see rather than something they have to guess at.

How does a family member usually pay for a business?

Rarely in cash. The typical structure is a small deposit from their own savings, some borrowing where the business has assets or stable enough profits to support it, and a large deferred element paid to the seller in instalments over several years out of the business future profits. That makes the seller the largest lender in the deal, usually unsecured, which is the central risk to understand before agreeing terms.

What happens if my family member cannot keep up the payments?

In most structures the deferred payments to the seller are the softest line, so they are the first thing to flex when a year comes in below plan. The bank loan is documented and secured; your instalment is neither. If those instalments are also your retirement income, decide in advance what actually happens when one is missed, write it down, and make sure you can live on the part of the price that is not deferred.

How do you keep it fair between children when only one takes over the business?

Start by writing down three numbers: the independently assessed value of the business, the price the buying child is actually paying, and the difference between them. That difference is what the buying child has received beyond the deal itself, and whether you count it when dividing anything else is the whole of the fairness question. There is no formula that settles it, but a decision the family understands survives far better than one they have to reconstruct later.
