Navigating the 2027 CGT Reforms: A Strategic Playbook for Australian Business Exits

The End of the Standard Discount

The passage of the Treasury Laws Amendment Act in June 2026 fundamentally altered the financial reality of selling an Australian enterprise. On July 1, 2027, the general 50% Capital Gains Tax (CGT) discount for individuals, trusts, and partnerships disappears. The government replaces it with cost-base indexation and a strict 30% minimum tax floor. For founders exiting a mid-market company, relying on outdated tax assumptions could easily double the final tax bill on post-2027 gains.

However, the legislation leaves the Division 152 Small Business CGT Concessions intact. This creates a high-stakes divergence in how M&A transactions are taxed. This article outlines the structural shifts in the Australian business sales market and details how owners must adapt their exit planning, deal structuring, and valuation strategies over the next 24 months to protect their equity.

The Divergent Tax Pathways Under Division 152

The federal budget reforms drew a hard line between businesses that qualify for concessions and those that do not. While the broad 50% CGT discount is gone, the government expanded the small business safety net. Starting July 2027, the aggregated turnover threshold for the 50% active asset reduction jumps from $2 million to $10 million.

If your enterprise falls under this new threshold, or passes the long-standing $6 million maximum net asset value test, you can still stack the four Division 152 concessions. These include the 15-year exemption, the 50% active asset reduction, the retirement exemption, and the small business rollover. The rollover concession, for instance, allows you to defer a capital gain for two years, or longer if you acquire a replacement active asset within a specific timeframe.

A transaction utilizing the 15-year exemption—available if you are over 55, retiring, and have held active business assets for 15 years—can still result in a completely tax-free exit. If you miss these thresholds by even a small margin, the financial penalty is severe. Managing retained earnings, surplus cash, and shareholder loans in the years leading up to a transaction is now a primary requirement for wealth preservation.

Defending Your Valuation Before Transition

The transition to the new tax regime requires establishing a firm historical cost base. Any owner planning to sell your business after the July 2027 cutoff must secure an independent, ATO-compliant market valuation near the transition date. For SME owners operating in the $3 million to $30 million enterprise value range, this is non-negotiable.

Without a formal valuation, the Australian Taxation Office defaults to a straight-line apportionment formula. This assumes flat growth across your entire holding period, dragging pre-2027 capital gains into the higher tax bracket.

You cannot rely on back-of-the-napkin earnings multiples. The ATO actively scrutinizes valuations that fail to explain methodologies, lack support for normalized earnings, or ignore related-party transactions. A defensible valuation must align with APES 225 standards and rely on rigorous discounted cash flow models or comparable public company metrics. Engaging an independent valuer early separates your pre-transition gains, which may still benefit from the legacy 50% discount rules, from the post-transition gains subject to the new indexation methodology.

Asset Sales vs. Share Sales in a High-Tax Environment

The mechanics of how you structure the transfer of ownership dictate your tax liabilities and your access to concessions. The friction between buyer preferences and seller tax outcomes is becoming more pronounced.

Buyers generally push for asset acquisitions. Purchasing individual assets provides them with depreciation step-ups, amortizable goodwill, and a clean break from the target company’s historical risk exposure.

For the seller, asset sales trigger multiple distinct CGT events. Tax applies separately to trading stock, depreciating assets, and goodwill. Extracting the proceeds from the corporate structure to the shareholders often incurs a secondary layer of taxation when profits are distributed.

Shareholders usually prefer selling shares directly. The proceeds bypass the company tax layer entirely, and the transaction constitutes a single CGT event. Given the incoming 30% minimum tax floor, negotiating a share sale over an asset sale often preserves significantly more wealth for the exiting founders. You must ensure your target entity has immaculate financial and legal records to convince a buyer to accept a share purchase.

Eligibility Criteria and Proactive Restructuring

Waiting until you receive a letter of intent to clean up your ownership structure guarantees a poor outcome. Eligibility for the most powerful tax exemptions requires careful analysis of connected entities, trust structures, and passive investment assets.

Passive assets sitting on the balance sheet can disqualify an otherwise eligible trading company from meeting the active asset test. Excess cash reserves or investment properties owned by the business artificially inflate your net asset value, pushing you over the $6 million cap.

Similarly, poorly drafted discretionary trust deeds can complicate the distribution of capital gains. A separate legislative measure, proposed to start in July 2028, introduces a 30% minimum tax on discretionary trust distributions. The interaction between these two timelines depends entirely on your trust deed, your beneficiaries, and your exact exit date.

Founders should map their corporate structures now. Move passive real estate out of the operating entity, manage the size test across your ownership period, and track your active asset status. If you are approaching the 15-year ownership mark, the difference between selling at year 14 and year 15 could equal the entire capital gains tax bill.

Preparing for the Realities of the M&A Market

The 2026 legislative overhaul removed the standard tax buffers that Australian business owners historically relied on. A successful transaction now requires defensive valuation work, precise entity structuring, and a clear understanding of the Division 152 thresholds long before you approach potential buyers.

A reactive approach to an acquisition offer is no longer viable. Founders must stress-test their corporate architecture today to ensure their post-tax payout aligns with the actual value they built over decades.
