Most owners think about valuation once, when a sale is on the horizon. By then the number is being used to make decisions that were set in motion years earlier.

A business valuation tells you what the business is worth to someone else. This is different from how much it earns, its turnover, or what you'd like it to be worth. Sometimes you don't get to choose whether one happens. Someone else requires it, and the only question is whether the number is yours or theirs. Other times nobody is asking, but knowing the figure changes what you decide to do next.

This page sets out both: the situations where a business valuation is required, and the ones where it's simply useful.

When is a business valuation required in Australia?

A business valuation is required whenever a third party needs an independent figure they can rely on. The main triggers are tax and ATO requirements, family law property settlements, financial reporting duties, and court proceedings. In each case the number will be examined by someone with an interest in testing it, so the reasoning behind it matters as much as the figure.

Do you need a business valuation for tax purposes?

Often, yes. Several situations in Australia call for a market value assessment:

• Capital gains tax on the sale of a business or transfer of shares

• Small business restructure rollovers, where transactions must occur at market value

• Employee share schemes, to determine the taxable value of shares or options

• Financial reporting under the accounting standards, including impairment testing and business combinations

• Stamp duty on business asset transfers, which varies by state

The common thread is that the ATO or the relevant regulator is entitled to test the figure. A business valuation prepared without that scrutiny in mind tends not to survive it.

Do you need a business valuation for a divorce or family law matter?

Usually, yes, where a business forms part of the property pool. The court will often appoint a single expert to value it, rather than accept competing reports from each side. Business valuation work done to that standard is clear and transparent. It lays out assumptions, shares evidence, and offers clear reasoning. Anyone can understand it, even without knowing the author. That reduces the ground left to argue over and gives the settlement a defensible basis.

Do you need a valuation for financial reporting?

Sometimes. Under the Australian Accounting Standards, a business valuation may be required for asset impairment testing, business combinations, or fair value reporting. Whether it applies depends on the size and structure of the business and the nature of the transaction, so it's worth confirming with your accountant which obligations attach to your situation.

When is a business valuation useful, even if nobody requires it?

A business valuation is worth getting whenever a decision depends on what the business is worth, even where no law or regulator demands one.

A clear, independent figure helps with several key tasks:

• Preparing for sale

• Planning succession

• Bringing in an investor

• Restructuring ownership

• Setting strategy

These tasks are vital for effective management and long-term success. Each role ensures the business operates smoothly and adapts to changes in the market.

In these situations the value of the exercise is timing: you learn where you stand while you can still act on it.

Should you get a business valuation before selling your business?

Yes, and earlier than most owners do. A valuation sets a realistic expectation before you're in a negotiation defending one. It also shows you what a buyer will price down: owner dependence, customer concentration, earnings that don't hold up under normalisation. Two or three years out, those are fixable. Three months out, they're discounts.

How does a business valuation help with succession or estate planning?

It gives everyone involved a number they can accept. Transferring a business to the next generation or splitting it among heirs usually works well until the value is actually tested. A documented, independent figure helps the arrangement hold up. It also gives the family member who’s not taking over a fair basis for what they get instead.

Do you need a valuation to bring in an investor or partner?

It helps both sides. An incoming investor wants to know the price reflects fair value, and so do you. An independent assessment gives everyone the same starting point and takes the argument off the table before it starts.

What about shareholder buy-outs and restructures?

Buy-outs, mergers and restructures all need a share price. The best time to establish how that price will be determined is when the shareholders' agreement is being drafted, not when it's triggered by someone leaving on bad terms. A valuation, or an agreed business valuation method, built into the agreement saves a dispute later.

Can a valuation help with strategy, outside any transaction?

Yes. A business valuation reveals what boosts or lowers your business's value. This insight helps you decide where to focus your efforts in the coming years. Most owners find something in the report they hadn’t weighed correctly. This exercise turns value into something you can manage, not just a number you see at the end.

Why does an independent valuer matter?

Because an adviser with a stake in the transaction has a reason to want a particular answer, and anyone reading the report later will notice. Independence means the figure is based on solid evidence and an objective view. It stands strong even when a buyer's adviser, a regulator, or an opposing expert searches for weaknesses. It's the difference between a number you can rely on and one you have to defend.

How do you decide whether you need a valuation?

Ask whether a decision is coming that depends on what the business is worth. If it is, better to know the figure and the reasoning behind it now, while you can still do something about either. A required valuation tells you where you already are. One you commission on your own timetable tells you something you can act on.
