When it comes time to sell or buy a business in South Australia, one of the first questions is how the transaction should be structured: as an asset sale or a share sale. Each approach has significant implications for ownership, liabilities, tax, and the future of the business.
Understanding the difference is essential for small business owners, families, and entrepreneurs planning to buy or sell in Adelaide and beyond.
What is an Asset Sale?
In an asset sale, the buyer purchases selected assets of the business. These can include:
Plant, equipment and stock
Intellectual property (trademarks, trade names, domain names)
Goodwill and customer lists
Leasehold interests or freehold property
The business entity itself (usually the company or trust) remains with the seller. Importantly, the buyer generally does not take on the seller’s liabilities unless agreed.
What is a Share Sale?
In a share sale, the buyer acquires the company’s shares (or units in a trust). This means the buyer steps into the shoes of the current owner and takes over everything the company owns and owes.
All assets, contracts and licences remain in place
All liabilities (including debts, tax obligations, employee entitlements) transfer with the company
The business continues operating under the same legal entity, but with a new owner
Key Differences Between Asset and Share Sales
Aspect | Asset Sale | Share Sale |
Ownership | Buyer takes specific assets | Buyer takes entire company |
Liabilities | Stay with seller (unless included) | Transfer to buyer |
Employees | Must be offered employment; entitlements negotiated | Automatically remain with company |
Contracts | May need to be re-assigned or novated | Usually continue without change |
Tax | Potential GST, CGT, and stamp duty issues on assets | No GST (sale of shares), CGT applies to seller |
Complexity | Simpler for buyers to exclude risks | May be simpler for seller; less disruption to business |
Practical Examples
Small café in Adelaide: Often sold as an asset sale – buyer wants the equipment, name, and goodwill but not the seller’s old debts.
Established incorporated company: A share sale may be preferred where contracts, licences, and brand reputation need to remain untouched.
Advantages and Risks
For Sellers
Asset sale: Can retain liabilities but may face higher tax and contract transfer issues.
Share sale: Cleaner exit; but buyer may reduce price to offset risks of inheriting liabilities.
For Buyers
Asset sale: Safer, as unwanted liabilities can be excluded.
Share sale: Preserves business continuity; but requires thorough due diligence to uncover hidden debts.
Tax and Legal Considerations in South Australia
Capital Gains Tax (CGT): Applies in both structures but calculated differently.
Goods and Services Tax (GST): Often applies to asset sales unless structured as a “going concern”. Share sales are not subject to GST.
Stamp Duty: May apply to certain asset transfers (e.g. real property, motor vehicles).
Employment Law: Under the Fair Work Act, employee entitlements may transfer differently depending on sale type.
Because the implications are complex, professional advice is essential to avoid unexpected costs.
FAQs
What is the simplest way to sell a business in SA?
There is no one-size-fits-all answer. Smaller businesses often use asset sales, while larger companies may prefer share sales.
Do buyers take on debts in an asset sale?
Generally no – unless debts are specifically included in the agreement.
Are employees automatically transferred in an asset sale?
No. Employees must be offered employment by the buyer, and accrued entitlements may need to be addressed.
Is GST payable on a share sale?
No. GST does not apply to the transfer of shares.
Which is better for small business owners?
Buyers usually prefer asset sales to minimise risk, while sellers may prefer share sales for a cleaner exit. Legal advice is crucial to decide which suits your circumstances.
