Asset Purchase vs Share Purchase: What Buyers Should Know
When you buy a business, you can buy the things the company owns, or you can buy the company itself. That choice, an asset purchase or a share purchase, decides which debts and problems come with the deal, which contracts survive, what happens to the staff and how the sale is taxed. This guide explains the differences in plain terms. It is general information, not legal or tax advice, so always confirm the details for your deal with a qualified adviser.
Key takeaways
- In an asset purchase you pick the assets you want and usually leave most past liabilities with the seller.
- In a share purchase (called a stock purchase in the US) you buy the company itself, with its full history, good and bad.
- Contracts, leases, licenses and permits often move more easily in a share purchase, but may need consent or reapplication in an asset purchase.
- Buyers often prefer asset deals and sellers often prefer share deals, mostly for liability and tax reasons, so structure is a negotiating point.
Most first-time buyers focus on the price. Experienced buyers spend just as much time on the structure, because two deals at the same price can leave you in very different positions. One gives you a clean set of equipment, customer lists and a brand. The other gives you a legal entity that may carry an old tax bill, a forgotten lawsuit or a supplier dispute you never heard about.
If you are still working through the overall buying process or the valuation, those topics have their own guides. Here we focus on one decision: what exactly you are buying.
The two structures in plain English
A business that operates as a corporation, LLC or limited company is a separate legal entity. It owns things (equipment, stock, contracts, a website, a brand) and it owes things (loans, taxes, obligations to customers and staff). The owners hold shares or membership interests in that entity.
Asset purchase
In an asset purchase, your company (often a new one you set up for the deal) buys specific assets from the seller's company. You list what you are taking: perhaps the equipment, inventory, trade name, website, phone numbers, customer list and goodwill. The seller's company stays in existence, keeps whatever you did not buy and remains responsible for its own past, unless you agree to take on certain liabilities.
Share purchase or stock purchase
In a share purchase, you buy the shares from the owners. In the US this is usually called a stock purchase, or a membership interest purchase for an LLC. In the UK it is a share purchase, documented in a share purchase agreement. The company itself does not change: same legal entity, same contracts, same bank accounts, same tax registrations, same history. Only the owners change.
Pro tip
If the seller is a sole proprietor or sole trader, there are no shares to buy. There is no separate entity, so the sale is effectively an asset purchase by default. The share purchase question only arises when the seller trades through a company.
Liabilities: what comes with the business
Liabilities are usually the biggest reason buyers prefer one structure over the other.
With a share purchase, the company keeps all of its liabilities, including ones nobody knows about yet. That can include unpaid taxes from earlier years, claims from former employees, product warranty problems, environmental issues at the premises or a customer who sues over work done before you arrived. Since you now own the company, those problems become your problems, even though they happened on the previous owner's watch.
With an asset purchase, you generally take only the liabilities you agree to take, such as specific supplier contracts or customer deposits. Most historic problems stay with the seller's entity. "Generally" is the key word: some obligations can follow the assets depending on local law, for example certain employment rights, some tax debts tied to the business, or liens and security interests registered against specific equipment. Your adviser will check what applies where you are buying.
Common mistake
Assuming a share purchase is fine because the seller "has no problems." Unknown liabilities are, by definition, the ones the seller has not told you about. In a share deal, your protection comes from due diligence, warranties and indemnities in the purchase agreement, and sometimes holding back part of the price, not from the seller's reassurance.
Contracts, leases, licenses and permits
Here the advantage often swings toward a share purchase.
In a share deal, the company that signed the lease, the supplier agreements and the customer contracts still exists, so those agreements usually continue without being reassigned. Watch for change of control clauses, though. Many leases, franchise agreements, bank facilities and larger customer contracts let the other party approve, renegotiate or terminate if the ownership changes.
In an asset deal, contracts belong to the seller's entity, so each one must be assigned to your company. Many contracts need the other party's consent to assign. Some landlords will want a new lease, a fresh guarantee or updated terms. Some customers may use the moment to renegotiate.
Licenses and permits can be the trickiest part. Some business licenses, alcohol licenses, health permits, professional registrations and government contracts are tied to a specific entity or person and cannot simply be transferred. In an asset purchase you may need to apply for your own, which takes time. Licensing rules vary a lot by country, state and city, so check with the issuing authority before you agree on a closing date.
| Item | Asset purchase | Share or stock purchase |
|---|---|---|
| Past liabilities | Mostly stay with the seller, with some exceptions | Stay with the company you now own |
| What you buy | Only the assets listed in the agreement | The whole company, everything it owns and owes |
| Customer and supplier contracts | Usually need assignment, often with consent | Usually continue, unless a change of control clause applies |
| Premises lease | Assignment or new lease, landlord involved | Continues, check for change of control terms |
| Licenses and permits | May need new applications | Often continue, but check notification rules |
| Employees | Depends on local law, may be rehired or transfer automatically | Stay employed by the same company |
| Paperwork | More documents, each asset transferred | Simpler transfer, more warranties and diligence |
Employees and the people side
In a share purchase, the employees stay employed by the same company. Their contracts, length of service, accrued holiday and benefits all continue.
In an asset purchase, the picture depends on where you are:
- In the US, the seller's company typically ends the employment of its staff and the buyer offers new employment to the people it wants to keep. Accrued vacation, benefit plans and any notice requirements need careful handling, and state rules differ.
- In the UK, transfer of undertakings rules (often called TUPE) usually mean employees transfer automatically to the buyer on their existing terms when a business is sold as a going concern. The buyer generally cannot simply pick and choose, and both sides have duties to inform and sometimes consult staff. Check GOV.UK guidance and take advice.
Example
Imagine you are buying a small UK café through an asset purchase. You plan to keep the brand and the equipment but bring in your own manager. Because the business is transferring as a going concern, the existing staff, including the current manager, may transfer to you automatically on their current terms. Your plans need to account for that, and your adviser may suggest how the purchase agreement should allocate any employment risks between you and the seller.
Tax treatment in general terms
Tax often decides which side wants which structure. The details depend heavily on the country, the type of entity and the deal, so treat what follows as a broad outline only.
Why buyers often like asset deals
In many systems, when you buy assets you can record them at the price you paid and claim depreciation or capital allowances on that value. Part of the price allocated to goodwill may also be deductible over time in some places. How you allocate the price across equipment, inventory, goodwill and other assets matters, and in the US both sides typically report the allocation to the IRS, so it should be agreed in writing.
Why sellers often like share deals
When owners sell shares, they are usually taxed once on their personal gain. When a company sells its assets, the company may pay tax on the gain, and the owners may pay tax again when they take the money out. Some regimes also offer reliefs that apply to share sales. As a result, sellers may ask for a higher price to accept an asset deal, or a lower price may be acceptable to them in a share deal.
Other tax points to ask about
- Transfer taxes or stamp duties that may apply to shares, property or certain assets.
- Sales tax or VAT on the transfer of assets, and whether a going concern relief applies (in the UK, ask about the rules for transfers of a going concern).
- Tax losses inside the company, which may or may not be usable after a change of ownership.
- Special elections in the US that can let a stock deal be treated like an asset deal for tax purposes in certain cases.
Which structure suits your deal?
Neither structure is always better. Use the comparison below to see where your deal leans, then decide with your lawyer and accountant.
An asset purchase may suit you when
- The seller is a sole trader or sole proprietor
- The company's history is unclear or records are poor
- You want only part of the business
- Tax benefits from asset values matter to your plan
- Key contracts and licenses are easy to transfer or replace
A share purchase may suit you when
- Valuable contracts or leases would be hard to reassign
- Licenses or permits are tied to the entity and slow to obtain
- The company is well run with clean, audited records
- Continuity for staff and customers is important
- The seller will only sell shares and the price reflects the risk
How buyers protect themselves in either deal
Whichever structure you choose, the same tools reduce your risk:
- Do proper due diligence. Review financial statements, tax filings, contracts, employment records, licenses, litigation and the condition of key assets. In a share deal, go deeper, because you inherit everything.
- Negotiate warranties and indemnities. These are the seller's written promises about the business and the agreement to compensate you if certain problems surface later.
- Consider holding back part of the price. An escrow, retention or deferred payment gives you something to claim against if a warranty turns out to be wrong.
- Check for liens and charges. Make sure assets are released from any lender's security at closing.
- Plan the transfers. List every contract, lease, license, domain, account and registration that must move or be reissued, and who will do it.
- Get specialist advice. A business lawyer and an accountant who handle small business sales will spot issues a generalist might miss.
Your deal structure checklist
- Confirm whether the seller trades as a company or as an individual
- List the assets you want and the liabilities you will accept
- Read key contracts and leases for assignment and change of control clauses
- Ask each licensing authority whether permits transfer or must be reissued
- Check how employees will transfer under your local rules
- Ask your accountant to compare after-tax outcomes for both structures
- Agree a written price allocation if you choose an asset deal
- Negotiate warranties, indemnities and any holdback
Frequently asked questions
Is a stock purchase the same as a share purchase?
Yes, broadly. "Stock purchase" is the common US term and "share purchase" is the common UK term. Both mean buying the ownership of the company rather than its individual assets. For an LLC, the US equivalent is usually called a membership interest purchase.
Can I avoid all liabilities with an asset purchase?
Not always. You avoid most of the seller's past liabilities, but some obligations can follow the business or specific assets, such as certain employee rights, registered liens or some tax matters, depending on local law. Due diligence and good contract terms still matter.
Does the structure affect SBA or bank financing?
It can. Lenders, including those offering US SBA 7(a) loans for business acquisitions, set their own terms and may have requirements about the structure, guarantees and what collateral is available. Talk to your lender early so the structure and the financing fit together.
Who decides the structure, the buyer or the seller?
Both. It is part of the negotiation. Buyers often push for an asset deal and sellers for a share deal, and the price, warranties and holdbacks are often adjusted to reach a structure both sides can accept.

The bottom line
An asset purchase lets you choose what you buy and usually leaves the seller's past behind, but transfers can be slower and messier. A share purchase keeps contracts, licenses and staff in place, but you inherit the company's entire history. Compare both on risk and after-tax outcome, not just price.
Rules on liabilities, employees and tax change and vary by country and state, so treat this as general information and check official sources such as the IRS, GOV.UK and HMRC, and work with a qualified lawyer and accountant before you sign.
