The 2026 Federal Budget has introduced one of the most significant proposed tax changes in decades, reshaping how Australians will calculate capital gains on investments, property, and business sales.

Treasurer Dr Jim Chalmers has announced plans to abolish the long-standing 50% Capital Gains Tax (CGT) discount and replace it with an inflation-indexed system, alongside a proposed 30% minimum tax floor on capital gains.

At Latitude Accountants, we help business owners and investors translate complex tax policy into practical decisions that protect wealth and improve long-term outcomes. This change is not just technical—it directly affects how Australians build, hold, and exit investments.

This guide breaks down what was announced, who is affected, and what you should consider next.

What Happened? Key CGT Changes Announced

The Federal Budget proposes a full redesign of Australia’s CGT system:

• Removal of the 50% CGT discount for assets held over 12 months
• Replacement with an inflation-based indexation method
• Introduction of a 30% minimum tax floor on capital gains
• Applies to gains realised after 1 July 2027 (proposed commencement)

Under the new system, taxpayers will no longer receive a flat discount on gains. Instead, the cost base of an asset will be adjusted for inflation before tax is calculated.

A limited exemption framework has also been proposed for newly built residential properties, allowing investors to choose between the old and new methods.

Why This Matters

This reform fundamentally shifts the balance between investment income and employment income in Australia.

For decades, the 50% CGT discount has encouraged long-term investing in property, shares, and private businesses. Removing it changes the after-tax return profile of nearly every asset class.

The key shift is this:
Tax will now depend more on “real gains after inflation” rather than nominal growth.

However, in high-growth markets, most investors are still likely to face significantly higher tax outcomes compared to the current system.

Who Should Pay Attention?

1. Small Business Owners

Business exits may become significantly more tax-intensive, particularly where cost bases are low and growth is high.

2. Property Investors

Capital growth above inflation will be taxed more heavily, especially in strong property markets like Sydney and Melbourne.

3. Share and Crypto Investors

High-growth and volatile assets will be disproportionately affected, as indexation offers limited protection against rapid gains.

4. Low-Income and First-Time Investors

The proposed 30% minimum tax floor may remove existing tax-free thresholds on modest capital gains.

What Are the Tax and Business Implications?

1. End of the CGT Discount Era

The removal of the 50% discount significantly increases taxable gains for most appreciating assets.

2. Inflation Indexation Advantage (Limited Cases)

If asset growth closely tracks inflation, taxable gains may be reduced—but this is unlikely in high-growth markets.

3. Higher Exit Taxes for Business Owners

Business sales will likely face materially higher effective tax rates, particularly for founder-led businesses with low cost bases.

4. Reduced Effectiveness of Trust Structures

Family trusts may lose efficiency in distributing capital gains to lower-tax beneficiaries due to the proposed 30% floor.

5. Increased Need for Record-Keeping

Accurate cost base tracking becomes critical under an indexation system to avoid overstating taxable gains.

What Should Business Owners and Investors Do Now?

Review Your Asset Portfolio

Identify high-growth assets that may be significantly impacted post-2027.

Assess Exit Timing

Consider whether planned asset sales should occur before the proposed transition date.

Re-Evaluate Investment Strategy

Future returns must be assessed on an after-tax, inflation-adjusted basis.

Review Business Structure

Business owners should reassess whether current structures remain tax-efficient under the proposed rules.

Common Mistakes to Avoid

• Treating proposed rules as already active law
• Making rushed asset sales without commercial reasoning
• Ignoring the impact of inflation indexation on returns
• Failing to update the cost base records
• Relying on generic tax assumptions or outdated calculators

Frequently Asked Questions

Is the new CGT system already in effect?

No. It is a proposed measure expected from 1 July 2027, subject to legislation.

Does this replace all CGT discounts?

Yes, the 50% general discount is proposed to be removed and replaced with indexation.

Are the main residences affected?

No. The principal residence exemption remains unchanged.

What is the 30% minimum tax?

It is a proposed floor ensuring capital gains are taxed at no less than 30%, regardless of income level.

Will small businesses be affected?

Yes. Business sales may face higher tax liabilities depending on structure and timing.

Final Thoughts

The 2026 Federal Budget signals a clear structural shift in how Australia taxes wealth creation. Moving from a simple 50% discount to an inflation-indexed system with a minimum tax floor will significantly reshape investment and business exit strategies.

While these changes are not yet law, the direction is clear: higher effective taxation on capital growth in strong-performing assets.

The focus now should not be reaction—it should be preparation.

Early planning gives investors and business owners the ability to make structured, strategic decisions rather than forced, last-minute adjustments.
