Asset Sale vs Share Sale: What Australian Business Sellers Need to Know

When a buyer makes an offer for your business, there are two numbers that matter: the headline price, and what you actually walk away with after tax. Deal structure, whether the transaction is set up as an asset sale or a share sale, can shift that second number by six figures or more.

Most sellers don't know which structure they're agreeing to until after the offer lands. By then, the negotiating leverage to change it is largely gone. This article explains what each structure means, why the tax difference is real and material, and what you can do about it before you sign anything.

Why the Buyer Usually Gets to Choose

In practice, the buyer proposes the deal structure, and most SME buyers default to an asset sale. Their reasons are commercially rational: asset sales give them a clean start with no inherited liabilities, more control over what they acquire, and a better tax position on the assets they buy.

Unless you push back, with knowledge, leverage, and the right professional support, the structure will be whatever the buyer finds most convenient. Most sellers accept this without realising the cost. Running the process confidentially also matters here: a seller who has managed to keep the sale quiet until late in the process retains more negotiating leverage on structure than one whose sale is already market knowledge.

The dynamic is asymmetric. Buyers who do multiple acquisitions understand this completely. Sellers, who are usually doing this once, often don't know what they don't know. That gap tends to resolve in the buyer's favour.

What Is an Asset Sale?

In an asset sale, the buyer purchases specific business assets, equipment, intellectual property, client contracts, goodwill, stock, and whatever else is agreed. They do not acquire the company entity itself.

Your company, the legal structure, the ABN, the bank accounts, the registered entity, stays with you. So does everything inside it that the buyer didn't specifically agree to take: pre-existing employee entitlements, historical tax positions, pending disputes, and any liabilities that were sitting quietly in the background.

After settlement, you're left holding a corporate shell. Winding it down takes time and costs money. Any undiscovered liabilities that surface after settlement remain your problem. Learn more about working capital can affect your net proceeds. Learn more about broker fees and other costs.

From a CGT perspective, the gain on an asset sale is typically realised at the company or individual level, depending on how the assets are held. Companies don't access the 50% CGT discount available to individuals, so if the gain is realised inside a company, you're taxed on the full amount at the corporate rate (25% for base rate entities, 30% otherwise) before any distribution back to you triggers further tax. If assets are held personally or through a trust, the 50% discount may apply if they've been held for more than 12 months. The Small Business CGT Concessions, including the retirement exemption, 15-year exemption, and small business rollover, may also be available, subject to eligibility criteria.

What Is a Share Sale?

In a share sale, the buyer acquires the shares in your company. They don't cherry-pick assets, they buy the entire entity. Everything inside it transfers automatically: assets, contracts, goodwill, employees, IP, and any liabilities that were there before the deal closed.

For you as the seller, this is typically the cleaner exit. Once the shares are transferred and you receive your proceeds, you're done. There's no entity to wind down, no assets to novate, no employee entitlements to settle on a standalone basis. You hand over the shares and walk out.

The CGT treatment is generally more straightforward for individual shareholders. If you hold shares personally, or through a trust, and have held them for more than 12 months, the 50% CGT discount applies directly to your capital gain. Small Business CGT Concessions may stack on top, depending on whether your circumstances meet the relevant tests. In the right structure, a share sale can dramatically reduce or eliminate the CGT payable on what might otherwise be a significant gain.

The downside for the buyer is that they inherit everything, including unknown liabilities. That's why most buyers resist share sales, and why sellers who want one need to give buyers a reason to accept it.

The Tax Difference, and Why It's Large

The structure of your sale can change your after-tax outcome by $100,000 to $400,000 on a typical SME transaction. The exact amount depends on your structure, how assets are held, the cost base, and whether CGT concessions apply. But the direction of the difference is almost always the same: share sales are better for sellers. (For a comprehensive breakdown of all tax considerations when selling a business, including timing strategies and concession planning, see our detailed guide.)

Here is a simplified illustrative example, not tax advice, and not a substitute for working through your own numbers with an accountant.

Scenario: A business is sold for $3,000,000. The seller is an individual who holds the shares personally and has owned them for more than 12 months. The adjusted cost base is $500,000. The small business CGT concessions are assumed not to apply for the purposes of this comparison.

Item	Share Sale	Asset Sale (gain in company)
Sale proceeds	$3,000,000	$3,000,000
Less: cost base	($500,000)	($500,000)
Capital gain	$2,500,000	$2,500,000
50% CGT discount (individual)	($1,250,000)	Not available to company
Taxable amount	$1,250,000	$2,500,000
Tax payable (approx.)	~$562,500 at 45%	~$625,000 at 25% (corporate) + further tax on distribution
Estimated net proceeds	~$2,437,500	~$2,200,000–$2,375,000

The gap widens materially if: the assets have been held in a company for years with significant accumulated depreciation, the business involves goodwill or IP that doesn't attract the discount at entity level, or distribution of the after-tax proceeds from the company triggers additional tax in your hands. For professional services businesses in particular, where goodwill is often the primary asset, the structure of the deal interacts closely with how that goodwill is valued and taxed. In practice, the all-in difference between a well-structured share sale and an asset sale can easily exceed $200,000 on a $3M transaction, and considerably more if small business CGT concessions are in play for the share sale but not the asset sale.

What Buyers Prefer (and Why)

In Australia, most SME sales under $5 million are structured as asset sales. This is not accidental. Buyers consistently prefer asset sales for several well-founded commercial reasons:

• No inherited liabilities. In an asset sale, pre-completion disputes, ATO positions, employment claims, and any other legacy issues stay with the seller's entity. The buyer starts clean.
• Selective acquisition. The buyer can choose which assets to acquire and leave behind what they don't want, old equipment, unfavourable contracts, leases they'd rather not assume.
• Depreciation step-up. When assets are acquired at market value, the buyer resets their cost base. This generates additional depreciation deductions over subsequent years, which has real after-tax value.
• Simpler due diligence. A company-level legal and financial audit, including reviewing the entity's full history, all contracts, employment records, and regulatory compliance, is time-consuming and expensive. Asset sales narrow the scope considerably.
• Lower risk of surprises. Buyers know what they're getting in an asset sale because they specify it. In a share sale, unknown liabilities can surface months or years after settlement.

From a buyer's perspective, asset sales are rational. The risks they avoid are real. The tax benefit they receive is real. As a seller, understanding why they prefer it, rather than simply accepting it, is the starting point for any structural negotiation.

What Sellers Prefer (and Why)

Sellers almost universally prefer share sales. The commercial logic is just as clear:

• Cleaner exit. Once the shares transfer, you're out. No entity to wind down, no residual obligations, no PAYG to settle separately months after settlement.
• Better CGT treatment. Individual shareholders can access the 50% CGT discount directly. Small business concessions may apply on top, potentially reducing the tax to near zero in eligible situations.
• Retained company structure. If IP, trademarks, regulatory licences, or client contracts are tightly embedded in the company entity, a share sale transfers them automatically, no complex novation, no consent requirements from counterparties, no risk of losing them in transition.
• Less residual risk. In an asset sale, you can spend months after settlement still responsible for the corporate shell, including any liabilities that surface after the buyer has moved on. In a share sale, that risk transfers with the entity.

The practical reality is that buyers rarely agree to a share sale unless there's a compelling commercial reason to accept the additional risk. That reason is usually the presence of something that can't practically be transferred as an asset, a government licence, a key contract that requires consent to novate, or a regulatory approval tied to the entity itself. If your business has one of those elements, you have natural leverage to push for a share sale. If it doesn't, you'll need to create that leverage through the negotiation itself.

How to Negotiate the Structure

Structure negotiation is not a footnote, it's a core part of deal terms, and it needs to happen early. Once you've signed heads of agreement or a letter of intent, your leverage to change the structure is effectively gone. Here are three mechanisms that allow sellers to negotiate effectively:

Price grossing-up

If a buyer insists on an asset sale, the seller can negotiate a higher headline price to compensate for the additional tax burden. This is called a gross-up. The mechanics are straightforward: your accountant models the tax differential between the two structures given your specific circumstances, and that differential becomes the basis for a higher asking price in an asset sale scenario.

A buyer who understands the deal economics will often accept a modest gross-up rather than complicate the transaction with a share sale they're uncomfortable with. The negotiation becomes a question of how much of the tax difference each side is willing to absorb.

Warranty and indemnity insurance

Warranty and indemnity (W&I) insurance is increasingly common in Australian M&A above $1 million. The buyer takes out a policy that covers them if a warranty given by the seller in the sale agreement turns out to be false. If a pre-completion liability surfaces after settlement, the buyer claims on the policy rather than against you personally.

W&I insurance directly addresses the buyer's primary objection to share sales, the fear of unknown liabilities. With appropriate coverage in place, many buyers who would otherwise demand an asset sale can be comfortable completing a share sale. The premium is typically 1–2% of the insured amount, and it can be paid by either party as part of the overall deal terms.

Specific indemnities

Where there are identified historical risks, a pending ATO review, a former employee claim, a known warranty exposure, the seller can provide specific contractual indemnities covering those items. This gives the buyer protection for known risks without converting the whole deal to an asset sale. Indemnities of this kind are a normal feature of well-negotiated share sale agreements.

The practical takeaway from all three mechanisms is the same: get your accountant and a transaction lawyer involved before you accept any offer, even an indicative, non-binding one. The moment you've agreed in principle to a price and structure, your ability to reopen either one diminishes rapidly. The deals where sellers walk away with the best net outcome are invariably the ones where they understood the structure before the negotiation began, not after. That understanding also requires knowing what a buyer will actually scrutinise, and how a thorough due diligence process is likely to test the numbers you've presented.
