Can a buyer pick the profitable machines and leave the past liabilities behind, while the seller keeps the corporate shell and its tax history? That apparent contradiction is the practical choice at the heart of every Australian business sale in 2026, because an asset sale and a share sale deliver very different legal and commercial outcomes. This guide walks buyers and sellers through who actually buys what, how employees and tax are treated, what consents and due diligence matter, and the documents advisers will want to see. Follow these nine steps before Heads of Agreement to fix tax planning, diligence scope and post-closing risk allocation.
Which is the single structural choice that governs tax treatment, employee continuity, due diligence, third-party consents and stamp duty?
1. Frame the transaction objective and preferred risk allocation
Start with the objective. The core legal distinction is simple and it decides most of the rest. In a Share sale the buyer purchases the shares in the company that runs the business and therefore steps into the seller’s shoes. The buyer acquires the company with all of its assets, contracts, licences, employees and liabilities, both known and unknown. In an Asset sale the buyer acquires only specified assets and, if agreed, particular liabilities transferred out of the seller’s company. Parke Lawyers sums it up as the buyer in a share sale effectively becoming the existing company, while in an asset sale the corporate shell, its tax history and any undisclosed liabilities remain with the seller.
This first choice must be made early, ideally before Heads of Agreement. It determines the tax planning, the scope of due diligence, the warranty and indemnity structure the parties will negotiate, and the shape of completion mechanics. The commercial question to answer now is which party will carry legacy risk and how that will be priced into the deal.
2. Map employee and industrial relations consequences
Employment law pushes parties in different directions depending on structure. On a share sale the employing entity doesn't change, so employment relationships and accrued entitlements continue without individual terminations and re-hirings. That simplicity matters when continuity of service is commercially important.
On an asset sale employees don't transfer automatically. Common practice is that the seller terminates employment at completion and the buyer offers new contracts. Whether a legal transfer of business has occurred alters how service and accrued entitlements are treated. The transfer-of-business rules in Part 2-8 of the Fair Work Act 2009 (Cth) set the legal test.
Parties must identify whether the sale meets that test, and then negotiate whether service and entitlements will be preserved, paid out or adjusted through the purchase price or an employment transition agreement.
That negotiation affects price, settlement mechanics and post-closing integration. If preserving service is critical, a share sale avoids interruption. If the buyer wants to pick particular staff and leave others behind, an asset sale gives that option but requires careful compliance with Fair Work Act obligations and practical arrangements for accrued leave, redundancy and award coverage.
3. Assess tax and indirect tax outcomes
Tax is a primary driver of structure. A share sale is generally input-taxed under Division 40 of A New Tax System (Goods and Services Tax) Act 1999 (Cth), so GST doesn't ordinarily apply to the sale of shares. By contrast, an asset sale attracts GST unless the parties satisfy the conditions for a supply of a going concern in section 38-325 of the GST Act. Those statutory tests are precise and must be front of mind during negotiating and diligence phases.
Capital gains tax and eligibility for small business concessions will depend on whether the deal is of assets or shares, and on the seller’s specific circumstances. The brief recommendation is clear: involve your accountant early because CGT small business concessions and other tax outcomes are bespoke. Buyers also need to model stamp duty or transfer duty. For example, in Victoria transfer duty on assets is assessed under the Duties Act 2000 (Vic), and landholder duty can apply to share sales if the company holds Victorian land above the statutory threshold.
4. Scope and sequence due diligence according to structure
The breadth of due diligence follows the structure. In a share sale the buyer inherits the company’s corporate history so diligence must be wide and deep. That includes historical tax positions, contingent liabilities, regulatory breaches, contracts, litigation exposure and employment issues. Parke Lawyers and other advisers recommend comprehensive diligence followed by allocation of residual risk through warranties, indemnities, caps, baskets and survival periods.
In an asset sale the buyer can narrow exposure to the selected assets and agreed liabilities. Diligence can therefore be more targeted: title searches for assets, intellectual property checks, verification of stock, plant and equipment, and searches for security interests. The parties should sequence diligence so that the most deal-critical checks happen first. The choice of structure therefore controls adviser time, legal cost and the residual risk to be fixed in the sale documents.
5. Identify and plan third-party consents and licensing hurdles
Third-party consents often decide whether an asset sale is workable. Assigning customer contracts, supply agreements, commercial leases and certain licences and permits normally requires the counterparty’s consent. A share sale typically avoids individual assignments because the same legal entity remains a party to existing contracts. But beware change-of-control provisions. Some suppliers, lenders or counterparties have contractual triggers that apply on a share sale and may need consent too.
Some government licences aren't transferable at all. If that's the case, an asset sale may force the buyer to apply for new approvals after completion. Parties should compile a consent schedule early and obtain conditional waivers or pre-approvals where possible to avoid disruption after settlement. Early engagement reduces the risk that a seemingly clean asset deal stalls over a small number of stickier consents.
6. Design the commercial terms that allocate post-closing risk
Warranty and indemnity architecture differs by structure for an obvious reason: who carries the past. In share sales buyers take the company with unknown past events, so share sale agreements commonly include more extensive warranties and indemnities and detailed disclosure processes, often supported by a disclosure letter. In mid-market or larger deals parties may use warranty and indemnity insurance to bridge the gap between buyer protections and seller appetite for capped liabilities.
In asset sales sellers typically give fewer warranties because the buyer isn't acquiring the entire corporate history. Pricing mechanisms will reflect employee entitlements, tax risk, inventory valuation and retained assets. Negotiation points include liability caps, baskets, thresholds for making claims, survival periods for warranties, and whether an escrow is held to meet deferred claims. Each of these items should be referenced to the scope of transferred liabilities and any specific indemnities the seller is willing to accept.
7. Quantify transactional costs and the residual corporate profile
Practical costs diverge. Asset transfers can trigger multiple registrations and dealings with security registries. They require novations for contracts and individual assignments for licences, and each step attracts administrative and sometimes duty or GST consequences. Share sales spare the parties those individual transfers but can expose buyers to legacy liabilities that increase the cost of warranty insurance, or require escrow funds and vendor indemnities.
Sellers who want a clean break often prefer an asset sale to retain the corporate shell and its tax history. That choice leaves the seller with an entity to manage, including any residual tax attributes and retained liabilities. Buyers must weigh the administrative cost savings of a share sale against the potential long-tail exposures they inherit.
8. Execute completion and post-completion integration
Completion mechanics differ in form. Asset sales need conveyances, assignment deeds, novation agreements and the physical handover of inventory and plant. Share sales require transfer of share certificates, updates to the share register and compliance with any shareholders agreement mechanics. Post-completion, buyers should update registrations and file ASIC forms where relevant, and then begin systems and staff integration.
Sellers should plan for reporting and tax obligations that follow disposals, and for managing the retained corporate shell where an asset sale leaves one behind. Both sides benefit from a post-settlement risk-management regime that mirrors the agreed warranty and indemnity architecture, including claims processes, time limits and escrow mechanics.
9. Documentation checklist and adviser roles
The decisive documents vary with structure but the common list includes a Heads of Agreement or letter of intent, a tailored sale agreement, a disclosure schedule or letter, assignment and novation documents as required, and GST and stamp duty opinions. Employment transition agreements are necessary where staff move or are re-hired, and escrow arrangements or indemnity provisions are usual where deferred claims are possible. The brief recommends engaging a commercial lawyer to draft and negotiate the sale agreement and a tax adviser to model tax positions for both buyer and seller. For larger deals consider approaching warranty and indemnity insurance brokers early.
When legal advisers disagree on commercial emphasis, the facts of the transaction will decide. The firms consulted for this guide are consistent on the core legal distinctions and statutory references. Where the brief cites statute, rely on Part 2-8 of the Fair Work Act 2009 (Cth) for employee transfer rules, on section 38-325 and Division 40 of the A New Tax System (GST) Act 1999 (Cth) for GST questions, and on the Duties Act 2000 (Vic) for Victorian duty consequences. Where dollar thresholds or CGT eligibility are material, instruct the accountant to run tailored numbers because advisers don't publish fixed thresholds in general overviews.
Practical timing and sequencing. Work in this order: 1. Decide structure and record core points in Heads of Agreement, 2. Instruct tax and legal advisers to model outcomes, 3. Run targeted diligence, 4. Obtain critical third-party consents or conditional waivers, 5. Negotiate warranties, indemnities and pricing adjustments, and 6. Execute completion mechanics suited to the chosen structure. That sequence keeps cost and risk in step with commercial objectives.
Where to focus your advice budget. If you choose a share sale, allocate budget to broad historical diligence and warranty negotiation. If you choose an asset sale, budget for assignment and novation costs, licence transfers and targeted asset title checks. Either way, get clear GST and stamp duty advice early because those tax points change the headline economics.
Common failings to avoid. One repeated error is fixing structure late in negotiations. That delays tax modelling and exposes parties to ill-fitting Heads of Agreement terms. Another is underestimating consent hurdles in asset sales, which can frustrate otherwise agreed commercial terms. Finally, not linking warranty cap and survival periods to the real scope of transferred liabilities leaves parties exposed to mismatched expectations.
In short
1. Decide structure early because it controls tax, employees and diligence.
2. Ask your accountant about CGT concessions and your lawyer about GST and Victorian duty.
3. Use targeted due diligence for asset sales, comprehensive checks for share sales.
4. Compile consent schedules and get conditional waivers before settlement.
