Australia delivered its 2026–27 Federal Budget on 12 May 2026. For most inbound investors and business owners operating in Australia, the headline question isn’t whether these changes will affect them. It’s how quickly they need to respond.

The short answer? Sooner than you think.

This budget draws a clear line. It moves away from tax-driven investment structures and toward a harder, compliance-focused environment where the government expects genuine economic activity rather than clever paper arrangements. If you’ve been relying on structures that worked well five years ago, some of those assumptions are now being challenged directly.

Here’s what matters most, and what you should be thinking about.

1. Capital gains tax is being fundamentally redesigned

This is arguably the single biggest change in the budget for investors holding Australian assets.

From 1 July 2027, the 50% CGT discount that individuals, partnerships and trusts have enjoyed for decades will no longer apply to new capital gains. In its place, the government is returning to a pre-1999 model of CPI-based cost indexation, but with a floor: a minimum 30% tax rate on net capital gains.

In practice, this means after-tax returns on exit will be lower across most scenarios, and the way you model investment performance will need to change. Gains on assets acquired before 1 July 2027 but sold after that date will be split between two regimes, adding valuation complexity. Asset holders should be working toward locking down 1 July 2027 valuations early, given the ATO’s approved methodology may not be particularly generous.

One often-overlooked detail: pre-1985 CGT-free assets will, for the first time, be brought into the CGT net from 1 July 2027. If you have legacy holdings that have benefited from that exemption, this is an important planning consideration.

There is some relief for foreign resident investors in renewable energy assets, who will retain access to a 50% CGT discount. For everyone else, the exit economics of Australian asset ownership have changed.

2. Negative gearing on established residential property is over (for new acquisitions)

From 1 July 2027, properties acquired on or after 12 May 2026 will no longer allow negative gearing losses to be offset against salary or other income. Those losses will be quarantined and can only be applied against future rental income or capital gains from residential property.

This is a structural shift in how residential property investment works in Australia, not a minor tweak.

The grandfathering is genuinely good news for anyone who already owns negatively geared properties. Existing holdings are protected. But for inbound investors looking to deploy capital into Australian residential real estate going forward, the traditional buy-and-hold, negatively geared model loses a core part of its economic logic.

The pivot is toward new residential construction, build-to-rent developments, and properties held through widely held trusts and managed investment trusts, all of which are exempt from the restriction. Foreign investors prohibited from buying established homes (a ban extended to 30 June 2029) should now seriously model whether development-focused strategies or institutional housing structures better fit the new settings.

3. Discretionary trusts are being targeted directly

This one deserves particular attention for any investor or business owner using a discretionary trust structure in Australia.

From 1 July 2028, a flat 30% tax will apply to the net taxable income of discretionary trusts. This is aimed squarely at the income-splitting advantages that discretionary trusts have offered for decades, particularly the “bucket company” strategies where distributions are directed to lower-taxed beneficiaries or corporate entities.

There is a window to act. Rollover relief will be available from 1 July 2027, giving a three-year transition period to restructure into a fixed trust or company without triggering a capital gains event. That window is real and meaningful, but it requires proactive planning. Waiting until 2028 leaves little room for careful structuring.

One practical complexity worth noting: the legislation targets “discretionary trusts” but Australian tax law doesn’t define that term precisely. This means certain unit trusts and other hybrid structures with discretionary elements may find themselves unexpectedly caught. If you’re not certain whether your trust qualifies as “fixed” under the rules, get clarity before committing to a strategy.

4. FIRB approvals are getting faster for the right investments

Not everything in this budget represents additional friction for inbound investors. The foreign investment framework is being recalibrated in both directions.

The government has committed $47.5 million over four years to strengthen and streamline the FIRB process, with a new performance target of deciding all low-risk applications within 30 days from 1 January 2027. For investors in non-sensitive sectors with clean ownership structures and a track record of compliance, this could meaningfully compress deal timelines.

The context matters here. As of the second half of 2025, only 41% of commercial proposals were being processed within the existing 30-day statutory period, against a target of 50%. So the policy intent is clear, but implementation remains a work in progress.

For investments in critical minerals, defence supply chains, critical infrastructure, or data centres, the opposite applies. Expect longer timelines, deeper scrutiny, and more detailed questions about upstream ownership and financing. The budget allocates significant funds specifically to better risk identification and non-compliance tools, signalling that the government is building enforcement capability alongside streamlining.

Strategic sectors where the government actively wants foreign capital include critical minerals (with a $5 billion Critical Minerals Facility announced), energy transition, infrastructure, and new housing supply. Investors focused on these areas, particularly those from countries considered “like-minded” on supply chain security, will find the policy environment genuinely supportive.

5. The R&D incentive is being restructured, not removed

For inbound investors and businesses that rely on the R&D Tax Incentive to fund innovation in Australia, the changes taking effect from 1 July 2028 require reassessment.

The headline number is positive: offset rates increase by 4.5%, with the maximum rising to 48% for refundable claims. The expenditure cap increases from $150 million to $200 million, benefiting capital-intensive research businesses. The refundable offset also becomes available to companies with a turnover of up to $50 million, extending access to a broader group.

But there are catches. Eligibility for “supporting R&D activities” is being removed entirely, meaning expenditure must now meet the more stringent definition of core R&D activities to qualify. The minimum spend threshold increases from $20,000 to $50,000. Refundability will no longer be available to companies more than 10 years old.

The practical effect is that smaller or less technically rigorous claims may no longer qualify, while the incentive becomes more valuable for larger, genuine R&D programs. If you’re currently claiming the R&D offset, the time to review your eligibility and documentation frameworks is now, not in 2028.

The takeaway for business owners

This budget rewards investors who can move quickly and structure intelligently. The transition windows are real, the compliance focus is real, and the sectors being opened up for foreign capital represent genuine long-term opportunities.

The risk for those who wait is not just higher tax bills. It’s being caught mid-restructure when the window closes, or entering new investments under rules that have already changed.

At C2Z Advisory, we work with inbound investors and business owners navigating exactly these kinds of structural shifts. Whether you need to model your exit returns under the new CGT settings, review a trust structure before 2027, or identify where your investment strategy aligns with the sectors the government is actively backing, we can help you think it through clearly.
