Do You Inherit the Debt When You Buy a Business? (UK)

If I buy a business do I inherit the debt in the UK? The honest answer is: it depends entirely on how you structure the deal. Buy the company itself and you usually take on everything it owes, the loans, the tax, the disputes you haven't heard about yet. Buy only the assets and you can often leave most of the debt with the seller. Same business, same price tag, two completely different risk profiles. The structure is the lever, and most first-time buyers don't realise they have a hand on it until a solicitor explains it.

The two paths split right at the start. A share purchase means you buy the shares in the limited company. The company is a separate legal person under UK law, legally separate from the people who own it, and it keeps every right and obligation it had the day before you signed. You change the owner; you don't change the company. So its debts come with it.

An asset purchase means you buy the things the business uses to trade, the equipment, the stock, the brand, the customer list, the goodwill, and you leave the old company behind as an empty shell that the seller winds down. Because you never bought the company, you generally don't buy its liabilities either. There are exceptions, and we'll get to the ones that bite, but the default position is the opposite of a share deal.

This matters because the businesses you'll look at on a marketplace like our businesses for sale listings come in both shapes. A sole trader's café is almost always an asset deal. A £1.5m limited company with a brand, a lease and twelve staff could go either way, and which way you go changes what you're exposed to by potentially tens of thousands of pounds. The rest of this guide walks each structure, the liabilities that can still chase you even in an asset deal, how diligence surfaces hidden debt, and the contract tools that protect you. By the end you'll know which question to ask first when a deal lands on your desk.

A share purchase is the acquisition of the shares in a limited company, which means you step into the seller's shoes and own the company exactly as it stands. Because a UK limited company is a separate legal entity, it carries its own debts. When you buy the shares, the company doesn't change; only its owner does. So every liability sitting inside that company on completion day, disclosed or not, is now effectively yours through the value of what you bought.

That's the part buyers underestimate. It isn't just the bank loan on the balance sheet. A share purchase hands you:

• Bank loans, overdrafts and asset finance still outstanding
• Money owed to suppliers (trade creditors)
• Tax owed to HMRC: corporation tax, VAT, PAYE and any deferred balances
• Director's loan accounts that need settling
• Employee liabilities, accrued holiday, pension contributions, redundancy exposure
• Contingent liabilities: a customer dispute, a warranty claim on past work, a tribunal that hasn't been filed yet

The last category is the dangerous one. Disclosed debt you can price. It's the liability nobody mentioned, because the seller forgot, or hoped you wouldn't ask, that does the damage. A claim from a customer over a job finished two years ago lands on you, because it lands on the company, and you own the company now.

In a share purchase, you don't really buy a balance sheet. You buy a legal person with a memory. Everything it ever signed, owed or promised is still attached the morning after completion, and the only thing that changed overnight is whose name is on the share register.

So why does anyone choose a share purchase? Because it's often cleaner to run. The company keeps its name, its contracts, its trading history, its bank relationships and its licences. Customers and suppliers may not even notice the change of hands, which protects revenue. Contracts that would need re-signing in an asset deal often just continue. And for the seller it's usually more tax-efficient, which is why sellers of limited companies frequently push for a share deal and may accept a lower price to get one.

On cost, a share purchase carries its own tax. The buyer pays stamp duty of 0.5% on the consideration for the shares when the transaction is over £1,000. On a £600,000 share purchase that's £3,000, a footnote next to the liabilities you're absorbing, but a real number your budget should carry. The trade-off is the whole game: a share deal is simpler and often cheaper to execute, but you're buying the company's entire history, the good and the buried. That's why diligence and the right contract protections, which we cover below, matter far more in a share deal than anywhere else.

An asset purchase is where you buy specific assets and, if you choose, specific liabilities of a business, rather than the legal entity that owns them. You cherry-pick. The kit, the stock, the goodwill, the brand, the customer contracts and the website might all come across, while the old company keeps its bank loan, its tax bill and that dispute you'd rather not own. The seller then winds the empty shell down. This is the structure most buyers reach for when debt is the worry, and it's why the answer to whether you inherit debt is so often "not if you buy the assets."

The mechanics are a list, not a single transfer. In the sale agreement you and your solicitor itemise exactly what's being bought and, just as importantly, what isn't. Anything not on the list stays with the seller's company. That clarity is the protection: a debt that isn't named as a transferring liability simply doesn't follow the assets across. A trade creditor the seller owes £40,000 chases the old company, not you, because you never bought the entity that owes the money.

Asset deals suit some situations more than others:

• The target carries debt or risk you won't take on. The classic reason. You want the trade, not the baggage.
• You only want part of the business. One profitable division out of three, one shop out of a chain.
• The seller is a sole trader or partnership. There are no shares to buy, so an asset deal is the only structure available.
• You want a clean line under the past. A fresh entity with none of the old company's history can be easier to finance and insure.

The trade-offs are real, though, and they're mostly friction. Because you're not buying the company, its contracts don't automatically come with you. Each material customer and supplier agreement may need novating or re-signing, and a counterparty can use that moment to renegotiate or walk. Licences and permits the business trades on may not transfer and might need fresh applications. The brand and IP only come across if the agreement says so in writing, which is exactly the kind of thing buyers assume and then find wasn't done. And the seller often resists an asset deal because it can trigger a double tax charge, once in the company on the sale of assets, then again when they extract the cash, so expect price pushback. None of this is a reason to avoid an asset purchase. It's a reason to brief a solicitor properly and to read the next section closely, because "asset deal = no liabilities" is the single most expensive oversimplification in this whole topic.

Buying the assets doesn't give you a clean break from every liability. A handful of obligations attach to the business or its assets by law, no matter how carefully your sale agreement is worded, and these are the ones that catch buyers who assumed an asset purchase meant zero risk. Here are the business liabilities when buying that can still chase you in an asset deal.

Employees and TUPE

This is the big one, and it surprises almost everyone. When you buy a business as a going concern, the staff usually come with it whether you wanted them or not. Under the UK rules covering transfers and takeovers (TUPE), the employees' jobs transfer to the new owner, their existing terms and conditions transfer with them, and their continuity of employment is preserved. You can't quietly reset their holiday or notice terms after completion, and there are duties to inform and consult staff before the transfer happens. So the employee liabilities, accrued holiday, owed wages, the redundancy exposure if you later restructure, can land on you even though you only bought the assets. Get your solicitor to confirm TUPE applies to your deal, because for an asset purchase of a trading business it usually does, and getting it wrong is expensive.

Leases and the landlord's consent

If the business trades from premises, the lease is its own negotiation. A lease isn't an asset you can just pick up. To take it on you almost always need the landlord's consent to assign, and the landlord can attach conditions, ask for a rent deposit, or in some cases require the outgoing tenant to guarantee your performance. The repairing obligations transfer with you, so a full repairing and insuring lease can hand you a five-figure dilapidations bill down the line. None of that shows on the seller's balance sheet, but all of it is yours once you sign the assignment.

Certain taxes and VAT

Most of the seller's tax debt stays with the seller's company in an asset deal, which is the whole point. But not all of it. VAT is the one to watch: if the deal qualifies as a transfer of a going concern it can be outside the scope of VAT, but get the conditions wrong and VAT becomes payable on the asset values, a cash hit nobody budgeted for. And in specific situations HMRC can pursue a buyer for certain unpaid amounts connected to the business or transferred employees. Have your accountant confirm the VAT treatment in writing before completion, not after.

Product, environmental and other attaching liabilities

Depending on the sector, other obligations ride with the assets. Product liability for goods the old business sold, environmental clean-up duties tied to a site or its equipment, regulatory obligations attached to a licence. The pattern is the same throughout: liabilities that the law attaches to the business, the staff or the physical assets don't care how you structured the deal. The defence is to surface them in diligence and then write a specific indemnity into the contract, which is exactly where we go next.

Due diligence is the structured investigation you run on the target before signing, and on the question of debt it has one job: find every liability the seller hasn't volunteered. In a share deal that work is non-negotiable, because you inherit whatever it misses. In an asset deal it still matters, because of the liabilities that follow regardless. Either way, the debt you don't find in diligence is the debt you pay for later.

Start with what you can pull for free, before you ask the seller for anything. For a limited company, Companies House gives you the filed accounts, the confirmation statement, the officers and, critically, the register of charges, which shows secured debt: who's lent against the company and what they hold as security. A charge you didn't expect is a debt you didn't know about. Cross-check the filed accounts against the figures the seller hands you. They should reconcile. When they don't, you've found your first question.

Then go after the liabilities that hide. The checklist that's saved buyers real money:

• The full debt schedule: bank loans, overdrafts, asset finance, director's loans, invoice financing, and any personal guarantees the owner has given that a lender will want re-papering
• The HMRC position in writing: VAT, PAYE and corporation tax statements, plus any time-to-pay arrangement or open enquiry. Tax arrears love to surface after completion
• Off-balance-sheet commitments: operating leases, long supplier contracts, deferred income you'll have to deliver against, warranty obligations on past sales
• Contingent liabilities: threatened or live disputes, tribunal claims, customer complaints that could become refunds. Cross-check against any legal provisions in the accounts
• Working capital: aged debtors and creditors, because a business quietly funding itself by stretching its suppliers passes that strained balance straight to you

The cheapest debt to deal with is the one you find before you sign. The most expensive is the one that introduces itself three months after completion, when your money is already in the seller's account and your only route back is a contract clause you hopefully remembered to insist on.

The rule that protects you: anything the seller can't or won't evidence is itself a finding. "Trust me, it's all paid" is not evidence. If the seller stonewalls on the HMRC statements or the register of charges, assume the worst case and either price it in or build a specific protection into the contract. For the full process, including the financial, legal, commercial and operational pillars, work through the business due diligence checklist for UK buyers, and use the questions to ask when buying a business to script the conversations where debt tends to come up. Diligence is also where your offer gets sharper: a liability you uncover is a reason to revise the price, change the structure, or insist on the warranties we cover next.

Diligence finds the risks; warranties and indemnities are how the sale and purchase agreement allocates them. They're the two contract tools that decide who carries the cost if something you couldn't fully verify turns out to be wrong. Get them right and a buried liability becomes the seller's problem instead of yours. Skip them and "we didn't know" becomes an expensive lesson.

A warranty is a statement of fact the seller makes about the business, written into the contract. "The company has no debt other than what's listed in this schedule." "All tax due has been paid." "There are no disputes, threatened or actual." If a warranty turns out to be false and you suffer loss as a result, you have a claim for breach of contract. The seller is on the hook for the difference between what they promised and what was true. Warranties cover the things you reasonably expect to be a certain way and want a contractual right to recover on if they aren't.

An indemnity is stronger and more specific. It's a promise to reimburse you, pound for pound, for a particular identified risk, with no need to prove breach or loss in the same way. If diligence flags a possible VAT exposure or a live customer dispute, you don't warrant it, you indemnify against it: "if this specific liability crystallises, the seller pays it." Indemnities are where the worrying findings from diligence go to be neutralised. The pattern is simple: anything the seller couldn't evidence and you couldn't disprove becomes an indemnity.

In a share purchase, the warranties and indemnities are the difference between buying a company and buying a lawsuit. You inherit the company's liabilities by default; the warranties and indemnities are the contractual route to push the disclosed and discovered risks back onto the seller.

Two mechanics shape how much protection you actually get. First, the disclosure letter: alongside the warranties, the seller formally discloses exceptions, the things they're telling you aren't true so they can't be sued for them later. A warranty you've been told the exception to is no longer a warranty you can claim on, so read the disclosure letter as carefully as the warranties themselves. Second, the limits: sellers cap their liability with a time limit (often shorter for general warranties, longer for tax) and a financial cap, frequently tied to the purchase price. A warranty claim is also only worth what the seller can pay, which is why, on a debt-heavy target, buyers reach for the tools in the next section. None of this is DIY territory. The wording is your solicitor's job, but understanding what these clauses do lets you brief them on which risks you actually care about.

Retentions and completion accounts are the mechanisms that keep part of the price contingent on the business being what the seller said it was, so a warranty or indemnity claim isn't just a promise but money you can actually reach. A warranty is only as good as the seller's ability to pay when you call on it. These tools fix that by not handing all the cash over on day one.

A retention is the simplest version. A slice of the purchase price, say 10%, is held back in a joint account or by the solicitors for an agreed period, often six to twelve months. If a warranted liability surfaces in that window, an undisclosed debt, a tax bill, a dispute, the money comes out of the retention rather than chasing the seller through the courts. Whatever's left at the end of the period goes to the seller. It's a buyer's safety net for exactly the kind of hidden liability a share deal exposes you to, and sellers accept it because the alternative, a lower headline price, is usually worse for them.

Completion accounts solve a different problem: the gap between the estimated state of the business at signing and its actual state on completion day. Businesses move. Debt goes up, cash goes down, working capital shifts between the day you agreed a price and the day the money changes hands. With a completion accounts mechanism, the parties prepare a set of accounts drawn up to completion, and the price adjusts against agreed targets, typically for net debt and working capital. If the company turns out to carry £30,000 more debt at completion than the deal assumed, the price drops by £30,000. It directly answers the debt question: you pay for the business as it actually is on the day, not as it looked weeks earlier.

The alternative you'll hear about is a locked-box structure, where the price is fixed against a historical balance sheet date and the seller warrants nothing leaks value out of the business between then and completion. It's cleaner and faster, with no post-completion truing-up, but it shifts the timing risk to the buyer, so it works best when the accounts are recent and reliable.

For a debt-heavy or higher-risk target, buyers often combine these: an earn-out or deferred consideration that ties part of the price to future performance, plus a retention for warranty claims, plus completion accounts to catch debt movements. Each tool keeps some of your money out of the seller's hands until the relevant risk has passed. How you fund the upfront part, and how a deferred or retained chunk fits your lender's terms, is its own decision, covered in how to finance buying a business in the UK. The point here is that price isn't only a number; it's a structure, and the structure is where you defend yourself against debt you can't fully see.

Here's the head-to-head. The choice between a share purchase and an asset purchase is, more than anything, a choice about who carries the liabilities, but tax, complexity and the typical use case all pull on the decision too. Use this table to frame the conversation with your advisers; the right answer depends on the specific target, not on a rule of thumb.

Factor	Share purchase	Asset purchase
Liabilities	You inherit them all by default: debt, tax, disputes, contingent claims, disclosed or not	You take only the liabilities you name; most stay with the seller's company
Liabilities that still follow	n/a, you get everything	TUPE employees, leases, some VAT/tax, product and environmental duties
Tax for the buyer	Stamp duty 0.5% on the share price (over £1,000)	No share stamp duty; SDLT may apply if land/buildings are bought; VAT unless it qualifies as a going concern
Tax for the seller	Usually more efficient, one level of tax, often capital gains treatment	Can trigger a double tax charge, in the company then on extraction
Contracts and licences	Continue automatically; the company is unchanged	Often need novating or re-signing; licences may need fresh applications
Complexity	Simpler to execute, but needs deep diligence and heavy warranties	More moving parts in the transfer, but a cleaner break from the past
Buyer's main risk	Hidden and contingent liabilities you didn't find	Missing a contract or licence transfer; the liabilities that follow by law
Typical use	Established limited company, clean history, buyer wants continuity	Sole trader or partnership; debt-heavy target; buying part of a business
Who usually prefers it	Sellers of limited companies (cleaner, more tax-efficient)	Buyers worried about inherited debt and risk

The one-line version: a share purchase is simpler to run but you buy the whole history, so it lives or dies on diligence and warranties. An asset purchase is more fiddly to transfer but lets you leave the debt behind, subject to the handful of liabilities the law attaches anyway. Sellers of companies tend to want the share deal; buyers worried about debt tend to want the asset deal; the negotiation is often about meeting in the middle on price and protections. If you're still mapping the whole journey from search to completion, the how to buy a business in the UK guide sets the structure decision in the context of the full process.

So, if I buy a business do I inherit the debt in the UK? You now know the real answer: a share purchase hands you the company's liabilities by default, an asset purchase generally lets you leave them behind, and a short list of obligations, TUPE employees, leases, certain taxes, follow the business either way. The structure is the single biggest lever you control over what debt you take on, and choosing it well is worth more than almost any price negotiation.

This is one area where doing it alone is a false economy. The numbers make the case. A misjudged structure on a £600,000 deal can mean the difference between walking away clean and absorbing tens of thousands in undisclosed debt, against an accountant and solicitor fee that's a small fraction of that. Two professionals earn their keep here:

• An accountant to run financial diligence: verify the real debt position, confirm the HMRC and VAT status in writing, model the tax consequences of each structure for you and the seller, and price the completion-accounts adjustment so you pay for the business as it actually is.
• A solicitor to handle the legal side: read the register of charges, draft or review the share or asset purchase agreement, negotiate the warranties, indemnities and disclosure letter, confirm whether TUPE and going-concern VAT treatment apply, and build any retention into the contract.

You can and should still do the early work yourself. Pull the Companies House record, list the visible debt, ask the seller the direct questions, and decide in principle whether this is a share or an asset target before you spend a penny on advice. That groundwork makes your advisers faster and cheaper, and it means you walk into the room understanding the choice rather than nodding along to it. The buyers who get caught by inherited debt are almost always the ones who treated structure as a formality and signed whatever was put in front of them.

The through-line: whether you inherit a business's debt isn't fixed by the business, it's decided by the deal you build around it. Get the structure right, surface the liabilities in diligence, and lock the protections into the contract, and you can buy a perfectly good company that happens to carry debt without that debt becoming your problem.
