What Every Australian Business Owner Needs to Know Before Selling

Selling a business is one of the most significant financial events in an owner's life. Yet most approach it with far less preparation than they would a property sale — despite the process being considerably more complex, more confidential, and more consequential. This article draws on the Quinn M&A 2026 Seller Guide to outline what every seller needs to understand before going to market.

Is now the right time to sell?

There is rarely a perfect time to sell a business. But there are conditions that consistently produce better outcomes. The Australian private business M&A market in 2026 remains active — private equity continues to seek quality SME and mid-market assets, and strategic acquirers are using acquisitions to accelerate growth and enter new markets.

At the business level, the best time to sell is generally when your business is performing well, trending upward, and you have runway left. Selling from a position of strength — not fatigue — produces the strongest results.

What is your business actually worth?

Business valuation is both a science and a commercial judgement. Most privately held Australian businesses are valued using an earnings-based method — typically a multiple of EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation), adjusted to reflect normalised or sustainable earnings.

The EBITDA multiple varies significantly by sector, size, growth profile, customer concentration, contract certainty and management depth. Businesses with strong recurring revenue, proven systems and minimal owner reliance typically attract multiples of 5x to 8x or above. Owner-dependent businesses with variable earnings may achieve 2x to 4x.

What buyers actually pay on

Your reported profit in the tax return is rarely the figure buyers use. Most buyers will normalise your earnings — adding back genuine one-off costs, adjusting owner salary to a market-rate replacement, removing personal expenses run through the business, and smoothing one-off revenue windfalls or losses.

Understanding your normalised EBITDA — and what drives or discounts it — is the single most useful piece of preparation a seller can do before going to market.

What can kill a deal — and how to avoid it

Most deals that fall over do not fail at the negotiating table. They fail because of issues that were foreseeable — and in most cases fixable — before the process began. The seven most common deal killers are:

1. Poor or unverifiable financial records — buyers need three to five years of clean financials. Incomplete or inconsistent records erode confidence and price.
2. Customer concentration — if one or two customers account for the majority of revenue, buyers see risk they will price aggressively or use to walk away.
3. Owner dependency — if the business cannot operate without you, buyers face transition risk. Build management depth and documented systems before sale.
4. Lease and property issues — a lease that cannot be assigned, is about to expire, or carries onerous conditions can kill a deal at the last moment.
5. Undisclosed legal and tax issues — disputes, ATO debts, underpaid entitlements and unresolved shareholder matters all surface in due diligence. Resolve known issues early.
6. Unrealistic price expectations — enter the process with realistic expectations informed by qualified M&A advice, not comparable anecdotes.
7. Confidentiality breaches — premature disclosure to staff, customers or competitors can devastate value before the deal completes.

Tax, structure and timing

Tax is one of the most significant variables in any business sale. The difference between a well-structured and a poorly structured exit can be measured in hundreds of thousands — or millions — of dollars.

Key considerations

• Capital Gains Tax (CGT) — the sale of a business or its assets typically triggers CGT. Individuals and trusts may be eligible for the 50% discount where assets have been held for more than 12 months.
• Small business CGT concessions — if your business meets relevant tests (active asset, $6m net assets or $2m aggregated turnover), additional concessions may include the 15-year exemption, 50% active asset reduction, retirement exemption and rollover.
• Share sale vs. asset sale — CGT treatment differs by structure. Share sale may be more favourable personally, while asset sale may involve GST, stamp duty and different timing.
• Settlement timing — timing settlement relative to the financial year can produce meaningful tax savings where concessions or retirement exemptions apply.

Quinn M&A operates within The Quinn Group — giving sellers direct access to in-house accounting and tax advisers throughout the sale process. Tax structuring conversations happen in the same room as M&A strategy, not as an afterthought.
