Asset Sale vs Share Sale: Which Structure Fits Your Business

A buyer has put a credible offer in front of you. The price looks workable, but one question changes the entire conversation: should the buyer purchase your company's shares, or only the business assets? For an Australian founder, asset sale vs share sale isn't just a comparison of tax rates. It affects the contract date, GST, employee continuity, inherited liabilities, warranties, and what you can realistically keep after settlement.

Who this article is for: Australian founders, medical practice owners, professional firms and SME sellers weighing an asset sale or share sale.

Currency note: This article reflects Australian rules, thresholds and regulator guidance current as at 08/2026.

When the Sale Question First Hits a Business Owner

A Sydney SME owner may spend years building a profitable operation, then receive an offer that appears to answer the retirement or reinvestment question. The buyer's adviser soon asks whether the transaction should be an asset purchase or a share purchase. The headline price remains the same on paper, but the amount reaching the owner, the liabilities left behind and the work required before completion may change substantially.

The first ten minutes of a sale discussion should not begin with “Which rate is lower?” It should begin with “What exactly is being transferred, and what must remain with the seller?” A share sale usually transfers the company itself. An asset sale transfers selected business assets, and the original company generally remains in existence with anything excluded from the deal.

Founders often focus on staff continuity, lease assignments, customer contracts and professional licences before they focus on tax. That instinct is sound. A structure that looks attractive in a spreadsheet can become difficult if key contracts require consent, employees need to be rehired, or old compliance obligations remain inside the seller's company.

Practical rule: Compare both structures using the same commercial price, then adjust for tax, GST, duty, transfer costs, retained liabilities and the buyer's likely pricing response.

An early review of merger and acquisition advisory considerations can help identify whether the proposed structure matches the business you operate. The right answer is rarely universal. It depends on entity type, the age and nature of assets, the risk profile, the buyer's bargaining position and your plans after exit.

What an Asset Sale and a Share Sale Actually Transfer

An asset sale transfers identified items from the selling entity to the buyer. Those items may include goodwill, equipment, stock, intellectual property, customer relationships, leases and selected contracts. The buyer may also agree to assume specified liabilities, but the buyer doesn't automatically take everything the seller's company owes.

The selling entity continues after completion unless the owners later wind it up. It may retain cash, excluded assets, tax obligations, unpaid creditors, historical disputes and other liabilities. Each transfer needs careful documentation, and third-party consent may be required for contracts, leases, licences or financing arrangements.

A share sale works differently. The buyer acquires the shares in the company from its shareholders. The legal entity remains the same, so its assets, contracts, employees, leases, debts, tax history and contingent claims remain inside the company. The buyer gains control of the whole entity rather than selecting individual components.

That continuity can make a share sale operationally smoother, but it also means the buyer needs broad due diligence. A buyer may request warranties, indemnities, tax protections and price adjustments to address risks discovered in the company's history.

The distinction can be summarised this way:

Goodwill deserves particular attention because the value may sit in customer relationships, reputation, systems or personal expertise. A disciplined goodwill calculation approach can support the allocation and reduce disagreement during negotiation.

How Tax Treatment Differs Between the Two Structures

The contract date can settle the tax year before money changes hands. For a sale under contract, the capital gains tax event generally occurs when the contract is entered into, not at settlement. That date can affect the income year for the gain, the use of capital losses and access to small business CGT concessions.

The ATO's CGT discount guidance covers eligible assets. The 50% CGT discount can apply to eligible individuals and trustees, not companies, that have held shares or assets for at least 12 months. A company seller cannot claim that discount on its capital gain.

For a company seller, an asset sale may create tax at company level before proceeds reach the owners. The tax result depends on the asset sold, the selling entity, the ownership period and whether small business concessions are available. Those concessions can operate differently for business assets and shares, so the structure should be tested before the sale contract is signed. The capital gains tax discount guide provides a practical explanation of the discount rules.

A buyer usually receives a new tax cost base for assets acquired in an asset sale. Where the rules allow, that cost base may support future depreciation or amortisation deductions. A share buyer generally takes the company's existing tax history instead. The underlying assets do not automatically receive new tax values.

GST creates another clear distinction. Shares are generally input-taxed financial supplies, so GST is not charged on the share transfer itself. An asset sale is generally taxable if the seller is registered, or required to be registered, although a sale may qualify as a GST-free going concern under Division 38 and section 38-325 of the GST Act. The ATO states that GST generally needs to be accounted for when a registered business disposes of capital assets, including real property unless an exception applies. See its guidance on GST and disposal of capital assets.

State duty requires a separate review. Share transfers typically avoid direct stamp duty, while asset transfers can attract duty on dutiable property and landholder rules. In the Northern Territory, landholder duty thresholds and state-based rates can reach 5.95%, as outlined in Australian deal structuring guidance.

Liability, Employees and Warranty Risk on Each Side

Tax doesn't determine whether a transaction is safe. In many sales, liability transfer is the more important commercial question.

With an asset sale, the buyer can usually identify the contracts, assets and liabilities it wants to acquire. Trade creditors, historic employment claims, product disputes and old compliance issues may remain with the selling entity unless the agreement says otherwise. That doesn't remove the seller's exposure. The seller may still give warranties about the entire business and may need to fund retained liabilities after completion.

With a share sale, the buyer acquires the legal entity and its history. Existing tax positions, leases, employment obligations, payroll matters, contractual commitments and latent claims remain inside that company. The buyer therefore relies heavily on due diligence and contractual protection, including warranties, indemnities and limits on liability.

Employee treatment needs careful review under the Fair Work Act and applicable transfer-of-business rules. An asset transaction may involve employees ending employment with one entity and transferring or recommencing with another, while continuity of service and accrued entitlements can depend on the circumstances and documentation. A share sale usually leaves the employing entity unchanged, but a change in ownership can still affect consultation, incentives, senior management arrangements and retention terms.

Lease consent is a common closing issue. An asset sale may require an assignment or novation. A share sale may avoid an assignment but still trigger a change-of-control clause. Professional licences, privacy obligations and regulated approvals can create similar complications.

Warranty caps, indemnity exclusions and warranty and indemnity insurance can shift risk, but they don't eliminate the need for accurate disclosure. A structured business due diligence checklist helps both parties identify obligations before they become completion disputes.

Why the Lower Tax Rate Is Not Always the Better Outcome

A lower nominal tax result can be the wrong commercial result if it removes access to a valuable concession or forces the buyer to reduce the price.

Australian small business CGT concessions don't operate as a single automatic discount. Eligibility can depend on the entity, the asset, the ownership period and the active asset test. The active asset test may require the asset to have been active for at least half the ownership period, or 7.5 years in longer-held cases, according to business.gov.au guidance on CGT for business.

That matters because a share sale and an asset sale present different concession questions. A share sale may allow the shareholder to assess concessions on the shares, subject to the detailed requirements. An asset sale may assess the underlying goodwill, business premises or other active assets separately. If the ownership structure was changed late, the shares may not satisfy the relevant conditions even though the operating business has been active for a long period.

The opposite commercial pressure comes from the buyer. An asset sale may provide a more useful tax cost base and a cleaner liability perimeter. The buyer may therefore accept a higher price for assets than the seller's first tax comparison suggests, particularly where the acquired assets support future deductions.

The correct comparison is not tax on the sale price. It is the seller's net proceeds after tax, GST, duty, transaction costs, retained liabilities and any price adjustment needed to secure the buyer's preferred structure.

Modelled outcomes should include the contract date, settlement date, entity-level tax, shareholder tax, available concessions, GST treatment, duty, working capital and the owner's post-sale plans. For a founder considering retirement, reinvestment or a move into superannuation, flexibility can matter more than the lowest tax payable in one income year.

A Worked Example From a Sydney Medical Partnership

Castle Medical is a hypothetical GP partnership in Sydney. Its principals are considering a transaction valued at $2.4 million, but the practice is regulated and operationally dependent on its fitout, equipment, patient records, long lease and practitioner arrangements.

An asset sale could require the parties to identify and transfer each relevant item. The process may involve AHPRA notifications, Medicare and bulk-billing assignment considerations, lease novation, goodwill allocation and arrangements for records and privacy. The original partnership would generally remain responsible for liabilities that weren't assumed, then work through its wind-up.

A share sale of a service company holding the practice could preserve the company's existing contracts and operating arrangements. The buyer would, however, acquire the company with its payroll obligations, restrictive covenants, historic compliance position and any AHPRA-related conditions attached to the structure. The result would turn on the company's ownership, licences and the precise contractual terms.

It isn't responsible to invent a net outcome from the $2.4 million price without the partners' cost bases, ownership periods, entity tax position, concession eligibility, GST registration, asset allocation and state duty facts. A meaningful model would present scenarios rather than pretend the answer is known:

For Castle Medical, the regulated nature of the practice may outweigh a simple rate comparison. Provider arrangements, leases, patient records, professional indemnity and employment continuity need to be mapped before either party commits to a structure.

Choosing the Right Structure for Your Circumstances

There is no Australian default that works for every seller.

For many medical practices, an asset sale may be more practical because the buyer can acquire the operating assets it needs without taking the entire historical entity. That doesn't make the transfer simple. Medicare arrangements, premises, patient records, professional indemnity, employment obligations and regulatory notifications still require careful coordination.

For an established SME, a share sale may be worth pursuing where the company has clean records, stable contracts and a concession pathway that aligns with the shareholders' ownership history. Sellers who have held the relevant interests for a long period should test the 15-year exemption, active asset reduction, retirement exemption and rollover rules rather than assume an asset sale is automatically superior.

Foreign sellers need an Australian tax and treaty review before choosing a structure. An asset sale may be administratively lighter in some circumstances, but the result depends on residency, the seller's corporate group, Australian assets and available relief. Treaty assumptions shouldn't replace transaction-specific advice.

Buyer power can reverse the preferred outcome. A skilled acquirer often prefers assets because it can limit assumed liabilities and obtain a more useful tax cost base. A seller seeking a share sale may need to negotiate a price adjustment, retention arrangement or earn-out to compensate the buyer for additional risk.

Founders should understand deal structure implications before signing a term sheet. The inputs that change the answer include entity type, asset age, ownership period, contingent liabilities, lease assignability, employee arrangements, regulatory status, GST treatment, state duty and your post-exit plans. Everglow's transaction and advisory services can help organise the commercial, tax and financial analysis before negotiations harden.

The better structure is the one that produces an acceptable net outcome while transferring the right risks and preserving a workable exit. An asset sale may suit a buyer seeking selectivity, while a share sale may suit a seller seeking continuity and concession access, but the right approach depends on the circumstances.

Frequently asked questions

Is an asset sale or share sale better for a seller?

A seller often prefers a share sale where the company has clean records, transferable contracts and shareholders who may qualify for relevant CGT concessions. An asset sale may still be preferable where the business contains liabilities or regulated arrangements that the buyer doesn't want to acquire. The answer should be based on net proceeds and risk, not the headline structure.

When does CGT apply to a business sale?

The Australian Taxation Office generally treats the CGT event as occurring when a sale contract is entered into, where there is a contract of sale. This means the contract date may determine the relevant income year even when settlement happens later. The asset or shares being sold, ownership period and seller entity still need separate analysis.

Is GST payable on an asset sale?

An asset sale can attract GST where the seller is registered or required to be registered. The sale may qualify as a GST-free going concern if the statutory requirements are satisfied. Shares are generally input-taxed financial supplies, so GST typically isn't charged on the share transfer itself.

Does a buyer inherit liabilities in a share sale?

The buyer acquires control of the company, so the company's existing liabilities remain within the entity. Those liabilities can include tax history, employment obligations, leases, contractual claims and undisclosed risks. Warranties, indemnities, disclosure and due diligence help allocate the risk, but they don't change the company's historical record.

Can small business CGT concessions apply to both structures?

Potentially, but the tests differ. A share sale examines the relevant shares and shareholder conditions, while an asset sale examines the underlying business assets and their use. The active asset test and other eligibility requirements must be checked against the actual ownership and operating history.
