Why 1 July 2027 Could Become a Critical Valuation Date for Private Assets in Australia

The proposed 2026-27 Federal Budget CGT reforms could make 1 July 2027 an important valuation date for private assets.  From that date, the Government proposes to replace the current 50% CGT discount with cost base indexation and introduce a minimum 30% tax rate on capital gains.

These measures are currently proposed and not yet law. However, if enacted in their announced form, they could create a significant transition-date valuation challenge for private asset holders.

In effect, the reforms introduce a “valuation reset point” that is straightforward for listed assets, but significantly more complex for private markets.

For private capital managers, the key issue is that gains before and after 1 July 2027 will be treated differently.  This means private assets will require a supportable and well-documented value at that date. That value may affect tax outcomes, investor allocations, unit pricing, fund accounting, audit review and potential future disputes.

How the current CGT discount works

Under the current system, investors generally receive a 50% CGT discount if they hold an asset for more than 12 months.  For example, if an investor buys an asset for $100 and later sells it for $200 the capital gain is $100.  With the 50% discount, only $50 is taxable. 

How the proposed indexation approach would work

Under the proposed system, the 50% discount would be replaced by cost base indexation. Instead of automatically taxing only half the gain, the original cost base would be adjusted for inflation.  Using the same example, assume the investor buys the asset for $100, inflation over the holding period is 20%, and the asset is sold for $200.  The indexed cost base becomes $120, so the taxable gain is $200 - $120 = $80.

This highlights the key difference: while indexation provides relief for inflation, it can be less favourable for high growth assets.  Where asset values increase significantly above inflation, a larger proportion of that value creation becomes taxable.

For simplicity, the examples throughout this article calculate the gain amount subject to tax rather than the final tax payable, which will depend on taxpayer circumstances, marginal tax rates, fund structures and the proposed 30% minimum tax.

Why growth equity and venture capital are especially affected

Growth equity, venture capital, private equity, real assets and other capital-appreciation strategies are likely to be more exposed because they aim to generate returns well above inflation through operational improvement, earnings growth, leverage, asset development, restructuring or multiple expansion.

As a result, a larger share of value creation may become taxable under the new rules.  This could affect post-tax IRRs, carried interest, management equity, exit timing and pricing, and relative attractiveness versus other asset classes.

Private credit: less exposed, but still relevant

Private credit is generally less affected because returns mainly come from interest income and fees rather than capital gains. However, capital gains can still arise in certain situations.  For example, assume a distressed loan is purchased for $60, later sold for $90, and cumulative inflation is 20%.  Under the current system, the capital gain is $30 of which $15 is taxable.  Under indexation, the cost base becomes $72 and $18 is taxable.

This shows that the reforms remain relevant for loans acquired at a discount, restructured positions, secondary trades or assets sold at a premium.

The exposure may be greater where private credit strategies include equity kickers, warrants, distressed purchases, restructurings, PIK instruments, loan-to-own outcomes or secondary trades at material discounts or premiums.

Why 1 July 2027 is an important valuation date

The transition date is critical because gains must be split into pre- and post- transition gains.  For example, assume a private equity fund:

• Purchased an asset in 2022 for $100
• Valued the asset at $160 on 1 July 2027
• Sold it for $220 in 2030
• Post-2027 inflation is 10%

The gain amounts subject to tax are:

The 1 July 2027 valuation is likely to become a critical reference point for separating pre-transition and post-transition gains, subject to the final transitional rules.

Valuation sensitivity and subjectivity

Unlike listed assets, which have objective marking prices, private assets rely heavily on assumptions and judgement.  Consider two alternative scenarios:

Higher valuation (+20%)

Lower valuation (-20%)

This shows that valuation differences can materially shift tax outcomes.  It also creates a natural incentive to support higher valuations at 1 July 2027, as this would allocate more gains to the pre-transition regime.  However, any such valuation must be supportable and consistent with audit, governance and regulatory expectations.

Importantly, this valuation will likely be tested years later when the asset is realised and will need to withstand retrospective scrutiny from auditors and tax authorities.

Risks to investors

The 1 July 2027 valuation does not only affect tax calculations — it can also create financial risks for investors if it is not appropriately determined. If a valuation is set too high at the transition date, it may shift a greater proportion of gains into the pre‑transition regime, reducing the apparent future tax burden. While this may benefit exiting investors in the short term, it can result in new or remaining investors effectively bearing tax on gains that were generated before they invested. Conversely, if the valuation is too low, more gains may fall into the post‑transition regime, increasing the tax burden on those investors.

In this way, inaccuracies in valuation can create inter-investor equity issues, leading to unintended wealth transfers between different investor groups, distort after‑tax returns, and produce outcomes that are inconsistent with economic participation in the underlying assets.

Considerations for fund managers

For assets held across the transition date, managers will need to track gains accrued before and after 1 July 2027.  Future CGT outcomes will hinge critically on the 1 July 2027 valuation, particularly at the point of exit.  Valuation also affects financial reporting, investor reporting and unit pricing, and audit review. 

For open-ended funds, continuation vehicles and funds with secondary transfers, the transition valuation may become an inter-investor equity issue, not merely a tax compliance exercise, as different investors may bear unequal shares of future tax depending on when they enter or exit.

Key areas to consider

• Formal valuation vs formula.  The reforms may allow either a prescribed formula or a formal valuation.  Whilst a formula may be simpler and cheaper, it may not reflect assets with uneven value growth.  For example, a company may grow sharply after winning a major contract, or a credit asset that reprices after restructuring.  For many private assets, a formal valuation is likely to be more appropriate.
• Record keeping.  Private asset cost bases are complex and evolve over time.  For example follow-on investments, capex, restructuring costs, refinancing costs, transaction costs, and other adjustments.  In addition, a valuation prepared in 2027 may need to be defended years later. This increases the importance of robust documentation and record keeping.
• Valuation consistency.  Funds may have different values for NAV reporting, tax calculations, and internal portfolio monitoring. These differences must be explainable and defensible.
• Valuation governance.  Managers may need to support assumptions around discount rates, comparable transactions, credit spreads, impairment indicators, LTV, DSCR, terminal values and exit assumptions.  This aligns with broader trends such as increased scrutiny from investors and greater regulatory focus on valuation, disclosure, and fairness.  The CGT reforms add another layer – valuations will not only be scrutinised for reporting, but also for tax outcomes.

How independent valuations can help

Independent valuations can provide a structured, objective and defensible framework at the transition date and beyond.  They can:

• Support governance and board oversight
• Improve consistency across NAV, tax and reporting
• Provide an audit trail documenting assumptions and methodology

This is particularly valuable for private assets where judgement is significant. 

Using the earlier example, the $160 valuation on 1 July 2027 affects the allocation of gains between regimes, unit pricing, investor outcomes, audit and regulatory review.  The key issue is not just whether $160 is correct, but whether the manager can explain and defend why it was reasonable at that point in time.

Conclusion

The 2026–27 CGT reforms are fundamentally a tax change, but they have significant implications for private asset valuation.  By replacing the 50% CGT discount with indexation from 1 July 2027, the reforms require a clear separation of historical and future gains. For private assets, this separation depends on supportable valuations at the transition date. 

The issue is not simply whether a valuation appears reasonable today. It is whether that valuation can be evidenced, explained and defended years later when assets are realised and tax outcomes crystallise.

In a regime where valuation determines how gains are allocated across time, weak or inconsistent valuation evidence can translate directly into financial, tax and investor risk.  Early preparation will be critical.

Independent valuations can play an important role in providing robust, defensible valuation frameworks, supporting governance, and helping build stakeholder trust in a regime where valuation outcomes have direct tax and investor consequences.
