Selling Your Business: Key Tax & Legal Considerations You Need to Know

Thinking about selling your business in Australia? It’s a big milestone - and a chance to realise the value you’ve built.

To get the best outcome, you’ll want to manage two things well: the deal terms (legal) and the numbers (tax). The right structure, clean contracts and smart planning can help you maximise price, reduce risk and avoid last‑minute surprises.

In this guide, we’ll walk you through the key decisions, documents and compliance steps so you can sell with confidence.

Should You Do A Share Sale Or An Asset Sale?

The first decision usually shapes everything else: will the buyer purchase the company’s shares (a share sale), or will they buy the business assets from your entity (an asset sale)? Each path has different legal and tax consequences.

Share Sale: You Sell The Company

• What it means: The buyer acquires the shares in your company. The company itself stays the same - same ABN, contracts, employees and licences - but it now has new owners.
• Pros: Often simpler for operations to continue; some contracts and licences may not need assignment; can be cleaner for customers and suppliers.
• Cons: Buyer inherits all liabilities (past and present), so they usually ask for more warranties and indemnities; requires thorough due diligence.

For a deeper look at how these deals compare, see a practical overview of share sale vs asset sale. If you’re selling shares in a private company, it’s worth reviewing the typical process and documents involved in a sale of shares in a private company.

Asset Sale: You Sell The Business (Not The Entity)

• What it means: The buyer purchases specific assets (for example, goodwill, IP, stock, equipment) from your company or you as a sole trader/partnership. Your entity retains anything not expressly sold.
• Pros: Liabilities are easier to ring‑fence; you can keep or exclude certain assets; useful if your entity has legacy issues.
• Cons: Contracts, leases and licences usually need consent or assignment; employees may transfer or be terminated/re‑engaged; more “paperwork” to transition operations.

Whichever route you choose, align it with your tax position, the buyer’s preferences and any change‑of‑control restrictions in key contracts.

Step‑By‑Step: How To Prepare Your Business For Sale

Good preparation can increase price and speed up due diligence. Think of it as making the buyer’s “yes” easier.

1) Get Your House In Order

• Corporate records: Ensure company details, registers and meeting minutes are up to date. If you operate through a company, confirm the share register and constitution are accurate.
• Financials: Clean, recent and reconcilable financial statements. Many buyers will ask for management accounts and tax lodgements.
• Key contracts: Locate signed copies and check for change‑of‑control or assignment clauses in customer agreements, supply contracts, finance documents and your lease.
• Employees: Confirm roles, award coverage, leave balances and any incentive schemes. Be ready to explain how entitlements will be handled at completion.
• Intellectual property: Make sure brand assets are owned by the entity being sold, not by founders personally. If needed, centralise ownership before the sale.

2) Identify Consents, Transfers And Releases

• Contracts and leases: Map which agreements require consent or assignment. Landlords, key customers and software vendors often need to approve a transfer.
• Security interests: Check and tidy up the Personal Property Securities Register (PPSR). Buyers will expect assets to be transferred free of security interests and may require you to provide PPSR releases. If you need a refresher, here’s what the PPSR is and why it matters for your business.
• Licences and permits: Note which can transfer, which require fresh applications, and any notice periods to regulators.

3) Prepare A Clear Deal Structure And Timeline

• Heads of terms: Outline price, what’s included, assumptions (e.g. stock levels, cash/debt position), earn‑outs and handover support. This guides your sale documents.
• Due diligence: Assemble a data room early. The more complete it is, the faster the review.
• Completion roadmap: Track who is doing what and when (consents, releases, staff communications). Many sellers find a concise completion checklist helpful.

What Contracts Do You Need To Sell A Business?

Your contracts define the deal, allocate risk and reduce disputes later. The exact suite depends on whether you’re doing a share sale or an asset sale, but these are the common documents.

Core Sale Document

• Business Sale Agreement (asset sale): Sets out the assets included, purchase price, adjustments, warranties, indemnities, restraints and completion mechanics. If you’re selling an online‑only business, you may prefer a tailored online business sale agreement focused on IP and goodwill.
• Share Sale Agreement: Used for a share sale - addresses title to shares, company accounts, liabilities, warranties and post‑completion obligations. It often includes specific tax and litigation warranties.

Related Documents You May Need

• Assignment and novation documents: Many third‑party contracts need assignment or novation to move to the buyer. A quick primer on why this matters is in Assignment of Contracts.
• Lease transfer: Retail and commercial landlords typically require a formal assignment and their consent. A Deed of Assignment of Lease is standard here.
• Intellectual property transfer: Trade marks, domains, copyrights and designs should be assigned properly. Where brand value is central, factor in timing to transfer a trade mark.
• Employment documents: Letters of offer, transfer of business communications, and possibly Deeds of Release for departing senior staff.
• Vendor Finance Agreement (if applicable): If you’re funding part of the price, document the repayment schedule, security and default rights.

A specialist business sale lawyer can coordinate these documents so they align with your negotiated terms and the buyer’s due diligence findings.

Key Tax Issues When Selling In Australia

Tax outcomes depend on your structure (sole trader, trust, company), the deal type (asset vs share sale), the assets involved and your turnover/history. Work closely with your accountant, and ensure the tax position is reflected accurately in your sale documents.

Capital Gains Tax (CGT)

• What may be taxed: A sale of business goodwill, IP, or shares can trigger a capital gain event. The gain is generally sales proceeds minus your cost base.
• Small business CGT concessions: If you meet eligibility tests, concessions may reduce or defer CGT (for example, 15‑year exemption or 50% active asset reduction). Eligibility is specific - get advice before you sign heads of terms.
• Share sale vs asset sale: The CGT impact can differ materially between these paths, particularly for trusts and companies. Align your deal structure with your CGT strategy where possible.

Goods and Services Tax (GST)

• Going concern exemption: If you sell the business as a going concern and both parties are registered for GST, the sale may be GST‑free if the legal criteria are met. Your contract should deal with this expressly.
• Asset sales: If the going concern exemption doesn’t apply, some asset sales may attract GST. Ensure your price and completion adjustments are drafted on the correct GST basis.

Other Tax Considerations

• Balancing adjustments: Depreciating assets may trigger balancing adjustments when sold.
• Stock and work in progress: Agree how stock is valued at completion and ensure this aligns with tax rules and your accounting policies.
• Employee entitlements: Confirm whether the buyer will assume entitlements and how any provision affects price or completion adjustments.

Tax advice should inform your term sheet early - it’s harder to retrofit the right outcome after the commercial deal is “agreed in principle”.

Employees, Leases, Licences And Data: What Transfers And What Doesn’t?

Even once you’ve settled on deal structure, you’ll still need to plan how key operational pieces move across.

Employees And Fair Work Obligations

• Transfer of business: In an asset sale, employees can transfer to the buyer if the Fair Work “transfer of business” rules apply. This affects how service and some entitlements carry over.
• Redundancy vs re‑engagement: If the buyer doesn’t take some roles, you may need to manage redundancies. It’s best to get tailored redundancy advice so you meet consultation and notice obligations.
• Communications plan: Time your staff announcements with deal milestones and required consents.

Leases And Premises

• Landlord consent: Most commercial and retail leases restrict assignment. Build landlord approvals into your timeline and be ready with a lease assignment deed.
• Make‑good and bonds: Clarify who handles make‑good and how bonds/guarantees are replaced at completion.

Licences, Permits And Third‑Party Contracts

• Regulatory approvals: Some licences are not transferable and require a new application by the buyer. Factor approval time into your completion date.
• Key supplier and customer agreements: Identify change‑of‑control or assignment clauses early to avoid “consent bottlenecks”.

Intellectual Property And Data

• Trade marks and domains: Assign these formally at completion; ensure registrant details are updated. Where relevant, schedule the steps to transfer registered trade marks.
• Privacy compliance: If you’re transferring customer databases, confirm you’re permitted to do so and update your Privacy Policy and notices as needed. Some consents are purpose‑specific, especially for marketing lists.
• IT access and handover: Plan user access changes, repository transfers and escrow releases so handover is smooth.

Common Pitfalls To Avoid

• Unreleased security interests: A missed PPSR registration can delay settlement - obtain releases in advance.
• Incomplete consent trail: Landlord, franchisor or key customer consents can take longer than you think. Start early.
• Vague earn‑out terms: If part of the price depends on future performance, define the metrics, control rights and financial policies clearly.
• Overly broad warranties: Strike a fair balance and set sensible caps, baskets and limitation periods aligned with the deal value and diligence.

Key Takeaways

• Choosing between a share sale and an asset sale affects risk, paperwork and tax - align the structure with your objectives and key contracts.
• Strong preparation (clean financials, IP ownership, mapped consents and PPSR releases) makes diligence faster and can improve your sale price.
• Your primary contract - usually a Business Sale Agreement or share sale agreement - should capture price mechanics, warranties, restraints and a clear completion plan.
• Plan early for employees, leases, licences and data transfers so operations continue smoothly post‑completion.
• Tax can materially change your net outcome (CGT concessions, GST treatment, balancing adjustments) - get advice before you lock in terms.
• Document assignments, lease transfers and IP assignments properly to avoid gaps in rights after settlement.
