It is understanding how the transition rules work, how the Small Business CGT concessions interact, and why valuations before 30 June 2027 may become critically important.
What Is Changing?
Under the current rules, individuals and trusts generally receive a 50% CGT discount on assets held longer than 12 months.
From 1 July 2027, the Government proposes:
- removing the general 50% discount;
- replacing it with an inflation-indexation model;
- and introducing a minimum 30% effective tax rate on gains.
Importantly, the Small Business CGT concessions currently remain. That means the 15-year exemption, 50% active asset reduction, retirement exemption, and rollover relief still appear available for eligible business owners.
However, investors who do not qualify for the Small Business CGT concessions may face significantly higher effective tax outcomes once the general discount is removed.
The Transition Rule Is the Key Issue
The proposed rules currently indicate gains accrued up to 30 June 2027 remain under the existing rules. Gains accrued after 1 July 2027 move into the new regime.
That means the value of assets at 30 June 2027 could become extremely important.
Example: Transitional Rules
Assume: an asset was purchased for $1 million, its value at 30 June 2027 is $4 million, and it is later sold for $5 million.
| Gain Component | Tax Treatment |
|---|---|
| First $3m gain | Existing rules |
| Additional $1m gain | New rules |
The growth that occurred before 1 July 2027 preserves current treatment. Future growth after that date falls into the new regime.
This is why valuations before 30 June 2027 may become critically important.
Why This Matters for Business Owners
Many SME business owners currently rely on the general 50% CGT discount and the Small Business CGT concessions together. Those concessions can dramatically reduce tax.
Example: Current Rules for Business Owners
Assume: $1 million capital gain. Owner qualifies for the 50% CGT discount and 50% active asset reduction.
| Step | Amount |
|---|---|
| Capital gain | $1,000,000 |
| Less 50% CGT discount | ($500,000) |
| Remaining gain | $500,000 |
| Less 50% active asset reduction | ($250,000) |
| Taxable gain | $250,000 |
Approximate tax at top marginal rates: $117,500. Effective tax rate: 11.75%.
Example: Proposed Rules for Business Owners
Assume: general 50% discount removed. Active asset reduction still applies.
| Step | Amount |
|---|---|
| Capital gain | $1,000,000 |
| No general discount | — |
| Remaining gain | $1,000,000 |
| Less 50% active asset reduction | ($500,000) |
| Taxable gain | $500,000 |
Approximate tax at top marginal rate: $235,000, double the current rules.
This is why the interaction with the Small Business CGT concessions is now so important.
Why This Matters for Investors
Investors are in a very different position from business owners. Most investors do not qualify for the Small Business CGT concessions, rely almost entirely on the general 50% CGT discount, and may therefore experience a much larger increase in effective tax rates.
This particularly affects:
- property investors;
- share portfolio investors;
- family investment trusts;
- and individuals holding long-term passive investments.
Current Rules
Investors: $1M gain
$235,000
After 50% CGT discount, taxable gain is $500,000. Tax at top marginal rate. Effective rate: 23.5%.
Proposed Rules
Investors: $1M gain
$470,000
No discount available. Full $1M taxable at top marginal rate. Double the current outcome.
For many investors, this represents one of the largest increases in after-tax investment costs seen in decades.
The Biggest Risk
The biggest risk is not necessarily the law change itself. The biggest risk is assuming you qualify for concessions, but discovering too late that you do not.
For business owners, common issues include:
- partially qualifying only;
- exceeding asset thresholds;
- passive assets creating problems;
- or failing active asset eligibility tests.
For investors, the risk is often:
- assuming existing long-term investment strategies remain tax effective;
- failing to review ownership structures;
- or not obtaining valuations before the transition date.
Historically, the 50% CGT discount softened many of these issues. If that discount disappears, the tax exposure becomes much larger.
What Business Owners Should Do Now
Business owners should now review:
- whether they qualify for Small Business CGT concessions;
- ownership structures;
- trust structures;
- active asset eligibility;
- succession plans;
- and whether valuations should be obtained before 30 June 2027.
Because the transition date may become one of the most important tax planning dates Australian SMEs have seen in decades.
What Investors Should Do Now
Investors should now review:
- unrealised capital gains across investment portfolios;
- ownership structures for investment assets;
- trust and family group arrangements;
- whether assets should be restructured or realised before 1 July 2027;
- and whether formal valuations should be obtained before 30 June 2027.
For many investors, the removal of the general CGT discount could materially alter long-term investment returns and after-tax wealth planning strategies.
Questions to Ask Right Now
- Do we qualify for the Small Business CGT concessions?
- Are our assets classified as active assets?
- Do we exceed the $6 million net asset value threshold?
- What would our CGT position look like if we sold in the next 3 to 5 years?
- Should we obtain a formal valuation before 30 June 2027?
- Is our ownership structure still appropriate under the proposed rules?
- Do we have unrealised gains that need reviewing?
- Is our succession plan documented and stress-tested?
