Introduction

If you own, operate, or advise an Australian SME, at some point you will need a business valuation. It might be for a sale, a buy-sell agreement, CGT planning, a family law matter, or simply to understand what the business is worth for strategic decision-making.

This guide covers everything an Australian business owner or advisor needs to know about business valuation in 2026 — the methods, the regulatory context, the cost, and how to prepare. It draws on real Australian valuation practice, not textbook theory.


Why Business Valuation Matters More in 2026

The CGT reform context

The most significant development for business valuation in Australia right now is the proposed reform to the capital gains tax discount. Currently, individuals who hold an asset for at least 12 months receive a 50% discount on their capital gain. The Government has proposed scrapping this flat discount in favour of an indexation-based system that adjusts the cost base for inflation.

Here's why this matters for valuation: if indexation replaces the 50% discount, the effective tax rate on business sales will depend on (a) the period the asset was held and (b) the inflation rate over that period. A longer hold period with higher inflation works in the taxpayer's favour under indexation — but for typical SME holdings of 5-15 years, the indexation benefit is significantly less than the current 50% discount.

For a business valued at $2 million with a cost base of $500,000 held for 10 years:

  • Current law (50% discount): Capital gain $1.5m × 50% = $750,000 included in income
  • Proposed indexation (assuming ~3% CPI): Cost base indexed to ~$672,000, capital gain ~$1.328m included in income

The difference — $578,000 in additional taxable income — means every valuation prepared for CGT purposes now needs to consider which regime applies and model the tax consequences under both scenarios.

What this means for SME owners

Anyone planning a business sale, succession, or restructure in the next 12-24 months should be modelling the tax outcome under both the current 50% discount regime and a potential indexation regime. The valuation itself doesn't change — but the after-tax proceeds certainly do.


The Core Business Valuation Methods

Australian business valuations generally follow one of three approaches, each appropriate in different circumstances.

1. Capitalisation of Future Earnings (Capitalisation of Maintainable Earnings)

This is the most widely used method for established Australian SMEs. The valuer determines the maintainable earnings of the business (normalised EBITDA adjusted for non-recurring items, owner's salary adjustments, and other one-off factors) and applies a capitalisation rate that reflects the risk profile of the business, its industry, and market conditions.

Formula: Business Value = Maintainable Earnings ÷ Capitalisation Rate

Building on this method, see our practical walkthrough of how to build a three-way financial model in Excel — the foundation for determining maintainable earnings.

When to use: Established businesses with stable, predictable earnings. This covers most Australian SMEs — tradies, professional practices, retailers, manufacturers with consistent performance.

Example: A professional services firm with maintainable earnings of $400,000 and a capitalisation rate of 25% (a 4x multiple) is valued at $1.6 million.

2. Discounted Cash Flow (DCF)

DCF projects future cash flows over a discrete period (typically 3-5 years) and discounts them back to present value using a discount rate that reflects the business's cost of capital and risk profile. A terminal value captures the value beyond the projection period.

When to use: Growth businesses, startups, businesses with variable earnings, or where the near-term earnings trajectory differs significantly from the long-term sustainable level.

DCF is more subjective than capitalisation — small changes in the discount rate or terminal value assumptions can swing the valuation by 30-50%. Always cross-check DCF results against a market multiple approach.

3. Market-Based Approach (EBITDA Multiples)

This method applies observed market multiples (from comparable transactions or listed company comparables) to the subject business's earnings. The most common metric is EBITDA, but revenue multiples are used for early-stage or high-growth businesses.

When to use: As a cross-check against the earnings-based approaches, or as the primary method when good comparable transaction data is available.

Australian SME EBITDA multiples by industry (2026 indicative ranges):

  • Professional services: 3-5x EBITDA
  • Trades and construction: 2.5-4x EBITDA
  • Manufacturing: 3-5x EBITDA
  • Technology/SaaS: 4-8x EBITDA
  • Retail: 2-3.5x EBITDA
  • Healthcare: 4-7x EBITDA

These ranges are indicative. The specific multiple depends on business size, growth rate, customer concentration, competitive position, and the quality of financial reporting.

4. Asset-Based Approach

The business is valued as the sum of its net tangible assets (adjusted to market value where appropriate) plus any identifiable intangible assets.

When to use: Asset-heavy businesses (property development, construction), businesses being wound up, or as a value floor (minimum value) for any business.


The Valuation Process in Practice

Step 1: Define the purpose and value standard

The purpose of the valuation determines everything — the effective date, the methodology, the level of documentation, and the standard of value. Common valuation purposes include:

  • Market value for a potential sale or purchase
  • Fair value for financial reporting or shareholder disputes
  • Statutory value for CGT, stamp duty, or family law purposes

Step 2: Gather financial information

A thorough valuation requires at least 3-5 years of financial statements, management accounts, tax returns, budgets and forecasts, and supporting documentation on key assets, contracts, and customer relationships. The quality of the valuation depends directly on the quality of the financial records.

Step 3: Normalise earnings

The valuer adjusts reported profits to reflect the true sustainable earnings of the business. Common adjustments include:

  • Removing non-recurring items (one-off legal costs, asset sales, restructuring costs)
  • Adjusting owner's remuneration to market rates (many SME owners pay themselves through a combination of salary and dividends that differs from an arm's-length manager's salary)
  • Normalising rent to market rates if the business premises are owned by a related entity
  • Adjusting for related-party transactions that may not reflect market terms

Step 4: Select and apply valuation methodology

The valuer selects the primary method based on the business characteristics, applies it, and cross-checks against at least one alternative method.

Step 5: Consider valuation adjustments

The preliminary value is adjusted for:

  • Control premium or minority discount — a controlling interest is worth more than a minority stake
  • Marketability discount — a private company share is less liquid than a publicly traded equivalent
  • Key person dependency — businesses heavily reliant on the owner-operator attract a discount
  • Specific risk factors — customer concentration, industry cyclicality, regulatory exposure

Step 6: Document and report

A professional valuation report should clearly state the purpose, the valuation date, the methodology, the key assumptions, and the resulting value range. It should include sufficient detail for a third party (including the ATO) to understand and, if necessary, challenge the conclusion.


Valuation for CGT Purposes

When you need a valuation for CGT

Common CGT events that require business valuations include:

  • CGT event A1 — Disposal of a business asset: the market value is needed to calculate the capital gain
  • CGT event E2/E4 — Transfers to or from a trust or company
  • CGT event J2/J5 — Changes in trust or company structure that trigger a deemed disposal
  • Small business CGT concessions — The 15-year exemption, 50% active asset reduction, retirement exemption, and rollover all depend on satisfying the $6 million net asset value test or the $2 million turnover test (which require a valuation)

The proposed CGT discount reform and its impact on valuations

The current 50% CGT discount (for assets held more than 12 months) significantly reduces the tax impact of a business sale. The proposed move to indexation would:

  1. Eliminate the flat 50% reduction that currently applies regardless of holding period
  2. Replace it with CPI indexation of the cost base, which benefits longer-held assets but by considerably less than 50%
  3. Require valuers and taxpayers to maintain detailed records of the cost base for indexation calculations

For business valuation practitioners, this change means:

  • Valuation reports for CGT purposes must now explicitly address the applicable regime — which discount or indexation rules apply based on the date of acquisition and disposal
  • Modelling the after-tax position becomes part of the valuation engagement, not just the pre-tax business value
  • Transitional rules will need careful attention — assets acquired before the change date may be grandfathered under the old rules

Preparing for a Business Valuation

Whether you're selling, buying, or planning, preparation makes a significant difference to both the cost and the outcome.

What to have ready:

  • 3-5 years of financial statements (profit and loss, balance sheet, cash flow)
  • Detailed management accounts for the current year
  • Tax returns for the same period
  • Business activity statements (BAS) — these validate the reported revenue
  • Details of all material assets and liabilities
  • Customer and supplier lists with revenue concentration analysis
  • Employment agreements and details of key staff
  • Any existing business plans or forecasts
  • Lease agreements, franchise agreements, licensing arrangements

Common pitfalls:

  • Incomplete or inconsistent financial records (the number one cause of valuation delays)
  • Undeclared cash transactions that affect the reliability of reported earnings
  • Poorly documented related-party transactions
  • Required owner salary adjustments that significantly change the earnings base
  • Failure to consider the tax implications of the transaction structure

Choosing a Business Valuation Provider

For Australian SMEs, the most appropriate valuation provider depends on the purpose:

  • Chartered Accountant (CA) or CPA with valuation specialisation — Suitable for most SME valuations, CGT compliance, and strategic planning. A CA brings both the accounting expertise to analyse financial records and the commercial judgement to assess business quality.
  • Specialist valuation firm — Appropriate for complex, high-value, or litigious matters. More expensive but carries greater evidentiary weight.
  • Business broker — Provides a market-based estimate for a potential sale but is not suitable for formal valuation purposes (CGT, family law, dispute resolution).

For CGT-related valuations, always use a qualified independent valuer. The ATO has specific guidelines on what constitutes an acceptable valuation for tax purposes, and a self-assessed valuation — or one prepared by a party with a financial interest in the outcome — will not withstand scrutiny.


Conclusion

Business valuation is a critical skill for Australian SME owners, advisors, and investors. Whether you are planning an exit, restructuring, managing tax exposure, or simply seeking to understand the value you have built, a properly conducted valuation provides the foundation for informed decision-making.

The proposed changes to the CGT discount make professional valuation advice more important than ever. If you are considering a business transaction that may trigger a CGT event, engage a qualified valuer early — ideally before the transaction structure is finalised — to ensure you understand both the pre-tax business value and the after-tax outcome.
