Goodwill is one of the most negotiated, and most misunderstood, components of any business sale. It’s often the largest line item in the purchase price, and yet most business owners couldn’t explain exactly how it’s calculated, how it’s taxed, or why a buyer might push back hard on it.
This article covers what goodwill actually is, how it’s separated from other business assets, how it affects the tax outcome for sellers, and what buyers and sellers each need to understand before the negotiation starts.
What is goodwill in a business?
Goodwill is the value of a business above and beyond its identifiable tangible and intangible assets. It represents everything that makes the business worth more than the sum of its parts: the customer relationships, the reputation, the repeat revenue, the processes, the team, the brand.
In practical terms, when you pay 1.2 million AUD for a business with 400,000 AUD in identifiable assets, the 800,000 AUD difference is goodwill. The buyer is paying for something real, they just can’t touch it.
Goodwill is usually the largest component in the sale of a service business, a professional practice, or any business where the value is driven by relationships and reputation rather than physical assets.
Personal goodwill vs business goodwill
This distinction matters enormously, both for valuation and for tax.
Business goodwill
Business goodwill belongs to the entity, not the owner. It’s the value that exists regardless of who’s running the business, embedded in the systems, the brand, the contracts, the customer base, the processes. A new owner can step in and that value continues.
Examples include:
- Long-term contracts with clients
- A recognisable brand with market presence
- Documented processes that don’t depend on any individual
- A recurring revenue base with low churn
- Strong supplier relationships held by the business
Personal goodwill
Personal goodwill belongs to an individual, typically the founder or key principal. It’s the value that would walk out the door if that person left. It exists because of their personal relationships, expertise, reputation, or network.
A financial planning practice where 80% of clients would follow the adviser if they moved firms. A legal practice where the principal’s name is the brand. A consulting business where every client relationship runs through the founder.
Personal goodwill is the most contested element in any business sale. Buyers will argue aggressively to reduce it, because they’re right to ask whether that value actually transfers.
The most common mistake sellers make is pricing personal goodwill as if it were business goodwill. A buyer’s due diligence will test whether the value is transferable, and if it isn’t, the price won’t hold.
How goodwill is valued
Goodwill is just one part of valuing a business. See our EBITDA multiples guide for how buyers price the rest.
Goodwill is rarely valued in isolation. It’s typically calculated as the residual: what’s left after you subtract the value of identifiable assets from the total enterprise value.
The starting point is usually an EBITDA multiple. A business generating 500,000 AUD EBITDA trading at a 3x multiple has an enterprise value of 1.5 million AUD. If the identifiable assets (equipment, inventory, debtors) are worth 300,000 AUD, the implied goodwill is 1.2 million AUD.
The multiple applied to EBITDA is where goodwill gets negotiated. Buyers will push for a lower multiple, and therefore lower goodwill, when:
- Revenue is concentrated in one or two clients
- The business is heavily dependent on the owner
- There’s no documented process or systems
- The customer base is relationship-driven rather than contractual
- There’s significant key person risk in the leadership team
Sellers can justify a higher multiple, and higher goodwill, when:
-
- Revenue is recurring and contracted
- Customer retention is high and demonstrable
- The business can clearly operate without the founder
- There’s a capable management team in place
- The business is growing with a clear trajectory

How goodwill is taxed when you sell a business
This is where the distinction between personal and business goodwill has direct financial consequences.
When you sell goodwill as part of a business sale, the proceeds are generally treated as a capital gain. The gain is calculated as the difference between what you received for the goodwill and your cost base, which for most established businesses is close to zero, since goodwill was built over time rather than purchased.
That sounds painful. But the Australian tax system has significant concessions available to eligible small business owners that can reduce, or in some cases eliminate, the capital gains tax on goodwill.
The small business CGT concessions
If you meet the eligibility criteria, four concessions can apply to the goodwill component of your sale:
- 15-year exemption: if you’ve owned the business for 15 years or more and are aged 55 or older, the entire gain may be exempt
- 50% active asset reduction: reduces the taxable gain by 50% if the business is an active asset
- Retirement exemption: up to 500,000 AUD of the capital gain can be excluded from assessable income.
- Rollover: defer the gain if you’re acquiring a replacement asset within two years
These concessions interact with each other and have specific eligibility rules. Getting the structuring right before settlement, not after, is critical. See our detailed breakdown of small business CGT concessions for how each one works.
Personal goodwill and employment income
Here’s where it gets complicated. If what’s being sold is genuinely personal goodwill, the value that exists because of the owner’s personal relationships and expertise, the ATO may characterize some or all of that value as employment or services income rather than a capital gain.
The practical implication: employment income is taxed at marginal rates, not the concessional CGT rates. And the small business CGT concessions don’t apply to it.
This is one of the more technically complex areas of business sale taxation, and it’s heavily dependent on the specific facts. Proper structuring advice before signing anything is essential.
Goodwill in an asset sale vs a share sale
How goodwill is treated also depends on the sale structure.
In an asset sale, goodwill is identified and priced as a specific line item in the sale agreement. The tax treatment flows through to the vendor’s personal or entity tax position based on the concessions available.
In a share sale, goodwill isn’t broken out separately, the buyer is purchasing the company, which includes goodwill embedded in the entity’s value. This has different implications for both parties. Buyers in a share sale inherit the company’s history, including any liabilities. Sellers may benefit from the CGT discount on their shares rather than the business concessions, depending on their structure.
The choice between asset sale and share sale is one of the most consequential decisions in any business sale transaction. Our article on asset sale vs share sale covers the full comparison.
What buyers need to understand about goodwill
For buyers, goodwill is the riskiest part of the purchase price. It’s the component most likely to evaporate after settlement if the transition isn’t managed correctly.
The key questions a buyer should ask before paying for goodwill:
- How much of the revenue is contractual vs relationship-dependent?
- What happens to key client relationships if the owner exits within 12 months?
- Is the goodwill tied to one or two individuals, or is it genuinely embedded in the business?
- What transition support is the vendor providing, and for how long?
- Has the customer base been independently verified, or is the seller’s own data the only source?
A thorough financial due diligence process will test these questions with actual data: client tenure, revenue concentration, churn rates, and contract terms. That’s what buyers pay for when they engage an independent accountant.

What sellers need to do before going to market
If you want to maximise the goodwill component of your sale price, the preparation happens before you find a buyer, not during the negotiation.
The things that reduce goodwill value in a buyer’s mind are almost always fixable with lead time:
- Key person dependence: document your processes, build a management team, gradually reduce direct client contact
- Revenue concentration: diversify your client base, avoid letting any single client represent more than 15 to 20 percent of revenue
- Undocumented systems: build operating procedures that allow the business to run without the founder
- Informal client relationships: transition relationships from person to entity where possible
This preparation takes 12 to 24 months to do properly. The businesses that sell for the best prices are the ones where the vendor started thinking about exit well before they were ready to leave.
Our guide to selling a business in Australia covers the full preparation process.
Goodwill is built over years, but it’s valued on a single day. The preparation you do 18 months before going to market determines the number a buyer will accept.
The role of a good advisor
Goodwill is where deals get complicated, and where advisors earn their fees. A business broker will price the goodwill at whatever they think the market will bear. Your job is to know whether that number is defensible, understand the tax implications before you agree to it, and structure the deal in a way that maximises your after-tax outcome.
That’s what an independent accounting advisor does on the sell side. Not just the numbers: the structuring, the tax position, the negotiating rationale.

Frequently asked questions (FAQ)
Is goodwill always taxed as a capital gain?
In most cases, yes, goodwill is a capital gains tax asset. But if the ATO determines that what’s being sold is personal services rather than transferable business goodwill, it may be characterised as ordinary income. The facts of each transaction matter significantly.
Can you claim a deduction for goodwill you paid for a business?
For tax purposes, purchased goodwill may be included in your cost base for CGT purposes when you eventually sell. It doesn’t give rise to an ongoing deduction like equipment depreciation. The treatment is complex and depends on how the goodwill was allocated in the purchase agreement.
What happens if the buyer disputes the goodwill valuation?
Goodwill is the most negotiated component of any purchase price. Buyers will use due diligence findings, including customer concentration, owner dependence, and revenue trends, to push the price down. An independent valuation and a well-prepared sell-side due diligence pack give sellers the best position to defend their number.
Does goodwill affect stamp duty?
In some states, stamp duty is assessed on the transfer of business assets including goodwill. The rules vary by state and transaction type. This is worth checking early in the deal structuring process, as it affects the total cost of acquisition for the buyer, and therefore the negotiating dynamic.
