The 2026 Federal Budget has announced sweeping proposed changes to Capital Gains Tax and negative gearing that, if legislated, will fundamentally alter how separating couples divide their assets. If you are navigating a property settlement right now, understanding these reforms is not optional; it is essential to protecting your financial future.
The landscape of Australian family law property settlements is shifting on two fronts simultaneously. The Family Law Amendment Act 2024, effective 10 June 2025, has codified the four-step property framework that courts use to divide assets. Now, the 2026 Federal Budget is proposing to change the taxation rules that determine what those assets are actually worth after settlement. Together, these reforms demand a more informed, strategic approach to financial separation.
The measures discussed in this post are announced government proposals and remain subject to legislation passing Parliament. Final operation may differ from what has been announced, and you should obtain current professional advice before making decisions based on these changes.
What Are the 2026 Budget CGT Changes?
The 2026 Federal Budget proposes to replace the 50 percent Capital Gains Tax discount with cost base indexation and a 30 percent minimum tax rate on capital gains, from 1 July 2027. This is the largest proposed change to how investment gains are taxed in Australia in over two decades.
Under the current rules, if you hold an asset for more than 12 months, you receive a 50 percent discount on the capital gain when calculating your tax liability. Under the proposed regime, that discount would be replaced. Instead, you would be permitted to index your cost base for inflation, and any net gain would be taxed at a minimum rate of 30 percent, regardless of your marginal tax rate.
For separating couples, this means the embedded tax liability in investment properties, share portfolios, and business assets is likely to be substantially higher than it would have been under the old rules. When the practitioner assigned to your matter helps you identify and value the property pool under the four-step framework, these increased future liabilities must be carefully considered and disclosed.
Transitional rules will apply to assets held before 1 July 2027. The gain accrued up to that date will be taxed under the existing 50 percent discount rules, while gains accruing after that date will be subject to the new indexation and minimum tax regime. This split treatment adds complexity to valuations and requires careful calculation.
How Does This Affect Property Pool Valuations?
The future tax liability attached to an investment property or share portfolio is likely to be substantially higher under the proposed rules, directly affecting how assets are valued and divided during settlement negotiations. Courts and parties will need to account for these increased embedded liabilities when determining the net property pool.
Under the codified four-step property framework in the Family Law Act 1975, the first step requires identifying and valuing the entire property pool. This includes determining the net value of each asset after accounting for liabilities, including embedded tax liabilities. Courts have historically taken varying approaches to future CGT, sometimes discounting or ignoring it where a sale was not imminent. However, with a harsher and more structurally embedded tax regime, the argument for recognising these liabilities at their full present value becomes significantly stronger.
Consider a scenario where one party wishes to retain an investment property as part of their settlement. Under the old rules, the future CGT liability might have been discounted because the 50 percent discount made it relatively manageable. Under the proposed 30 percent minimum tax rate, the eventual tax bill on disposal would be materially higher. This affects the true value of what that party is receiving and must be factored into any just and equitable division.
The duty of disclosure under sections 71B and 90RI of the Family Law Act 1975 requires both parties to provide full and frank financial disclosure. This obligation extends to providing accurate information about the tax position of all assets, including any embedded CGT liabilities and the impact of any reform on those liabilities.
How Does Negative Gearing Change After Separation?
Negative gearing benefits are proposed to be limited for established residential properties acquired after 7:30pm AEST on 12 May 2026, with the changes taking effect from 1 July 2027. This would fundamentally alter the financial viability of retaining an investment property on a single income after separation.
Under the current rules, if your rental income does not cover the costs of holding an investment property (mortgage interest, rates, maintenance), you can deduct that net rental loss against your other taxable income, reducing your overall tax bill. This has historically made it feasible for a single-income household to retain an investment property after separation, even if the rental yield was modest.
From 1 July 2027, for established residential properties acquired after budget night, net rental losses are proposed to be quarantined: they could only be offset against future residential property income or capital gains from residential properties. They could no longer be deducted against wages or salary. For a party who acquires a new investment property as part of a settlement restructure after 12 May 2026, this means the holding costs would be higher in real terms.
This change is particularly relevant when parties are negotiating whether to sell the investment property and divide the proceeds, or whether one party retains it and compensates the other from different assets. The removal of negative gearing on established residential properties may tip the balance toward sale in many cases, which in turn triggers the new CGT rules discussed above.
Do CGT Rollover Rules Still Apply?
Yes, Capital Gains Tax rollover relief continues to apply when assets are transferred between separating spouses as part of a formal property settlement, provided the transfer is formalised through Consent Orders or a Binding Financial Agreement under the Family Law Act 1975.
This is an important point of reassurance. The CGT rollover provisions in the tax legislation ensure that when an investment property, shares, or other CGT assets are transferred from one party to the other as part of a property settlement, no CGT event is triggered at the time of transfer. The receiving party inherits the original cost base of the asset and the obligation to pay CGT is deferred until they eventually sell.
However, it is crucial to understand what this means under the proposed regime. The party who retains the asset is inheriting not just the asset, but also the full embedded tax liability that will crystallise under any new rules when they eventually sell. If you are the party retaining an investment property, you need to understand that your future CGT bill may be calculated under the proposed 30 percent minimum rate for any gains accruing after 1 July 2027.
This makes it essential to obtain proper financial advice before agreeing to retain assets with significant embedded gains. The practitioner assigned to your matter can help you understand how FDR provides the space to work through these calculations carefully, with input from your accountant or financial adviser, before you commit to any agreement.
How Are Family Trusts Affected?
The 2026 Federal Budget proposes a minimum 30 percent tax rate on discretionary trusts from 1 July 2028, with some exceptions. This is a tax on the trust itself rather than on distributions directly, but it would significantly reduce the effective benefit of streaming income to lower-taxed beneficiaries.
Family trusts are a common feature in Australian property settlements, particularly where one party operates a business or holds investments through a trust structure. The duty of disclosure requires full transparency regarding trust structures, control, and distribution history. Under the proposed measure, the value of streaming trust income to low-tax individuals would be diminished because the minimum tax floor would apply to the trust before distributions are received.
For spousal maintenance assessments, this is potentially significant. If one party relies on trust distributions as their primary income source, the court or the parties in FDR may need to account for the fact that distributions could be reduced by the operation of the minimum tax. A distribution that previously provided a certain standard of living could deliver less in net terms, potentially affecting both the payer's capacity and the recipient's needs assessment under the future needs adjustment at step three of the property framework.
Why Timing Your Settlement Matters Now
If legislated as announced, the transitional rules mean that settling before 1 July 2027 may allow parties to realise gains under the more favourable existing CGT discount, while delaying settlement could result in substantially higher tax liabilities on the same assets. Strategic timing of your property settlement has rarely been more financially significant.
This does not mean rushing into an unfair agreement. It means being informed and strategic about timing. If both parties hold assets with significant unrealised capital gains, there may be a genuine financial benefit to finalising your property settlement and implementing any necessary asset transfers before the new regime takes effect. Conversely, if the gains are modest or the assets are unlikely to be sold in the near future, the timing pressure may be less acute.
Family Dispute Resolution provides a faster, more efficient pathway to reaching agreement compared to litigation. Where contested court proceedings can take 18 to 36 months or longer, FDR allows parties to engage in structured negotiations and reach binding outcomes within weeks or months. In the current environment, where timing has genuine financial consequences, the efficiency of FDR becomes a tangible advantage.
What Should You Do Right Now?
If you are separated or contemplating separation, obtaining informed advice about the interaction between these tax reforms and your property settlement is the single most important step you can take right now to protect your financial position and ensure a fair outcome.
Start by ensuring you have a complete picture of your joint and individual assets, including any embedded CGT liabilities, trust structures, and investment properties. The duty of disclosure under the Family Law Act 1975 requires this transparency from both parties. If your former partner is not forthcoming with financial information, there are mechanisms available to compel disclosure.
Consider engaging an accountant alongside your family law process to model the tax implications of different settlement scenarios under both the current and proposed rules. In FDR, you have the flexibility to bring in your own financial experts to inform your negotiations, ensuring that any agreement you reach is based on accurate, current information.
The practice is here to help you navigate this intersection of tax reform and family law with clarity and confidence.
