CM Law's Ultimate 50 List - Separated Couples FAQ #11: What are the tax implications of separation?
Explore CM Lawyers’ divorce and separation services.
A property settlement should be assessed by what each person receives after tax, debt and transaction costs. Two assets with the same market value may leave very different amounts available to live on. Address tax before signing the settlement documents, while the proposed transfers and payment arrangements can still be checked.
Does separating automatically create a tax bill?
Separation alone does not automatically dispose of your assets for tax purposes. Selling or transferring assets, changing ownership arrangements and receiving income can create tax consequences. Australia also does not have joint individual tax returns: each person already reports their own taxable income, although spouse information can affect particular assessments.
Start with the proposed transactions, rather than assuming divorce makes every transfer tax free. Identify the legal owner, asset history, debts and intended recipient. My practical advice is to obtain tax estimates before agreeing on the amount each person should receive.
Which transfers qualify for relationship-breakdown CGT rollover?
The rollover can apply to qualifying asset transfers resulting from specified court orders, arbitration awards or formal agreements. It is not available merely because a couple has separated or signed a private arrangement. The relevant legislation, type of agreement, recipient and connection with the relationship breakdown must all be checked.
The ATO explains qualifying transfers, and Legal Aid NSW summarises the available documents. Some agreement routes also require separation with no reasonable likelihood of resuming cohabitation. If the conditions apply, the rollover operates automatically; the parties cannot simply elect to ignore it.
Does rollover remove the capital gain permanently?
Usually it defers the tax consequences rather than resetting the asset to its settlement value. For a post-CGT asset, the recipient generally takes over the transferor’s relevant cost base. When the recipient later disposes of the asset, the earlier ownership history can affect the gain and any available exemption.
An investment property valued for settlement is not necessarily acquired at that value for tax. Obtain the original purchase and improvement records, not just a current appraisal. Subdivision 126-A sets out the rollover framework; special rules apply to pre-CGT assets and certain other interests.
Will transferring the family home be completely exempt?
A family home may qualify for a main-residence exemption, but the label “family home” does not establish eligibility. Ownership dates, occupation, rental or business use, land area and residency can matter. Where rollover applies, the receiving spouse may need the former spouse’s ownership and use history for a later sale.
Main-residence rules following relationship breakdown require a separate assessment from rollover eligibility. Keep records of when each person occupied the property and any income-producing use. An exemption covering one period does not automatically cover every later period.
Moving out does not necessarily end all main-residence relief immediately. Continuing-main-residence rules may help, but they have conditions and can interact with another home and income-producing use. The commonly mentioned six-year rule is not an automatic exemption for every separated owner. Review the actual ownership and occupancy timeline.
Before renting out the property or buying elsewhere, obtain advice about the available choices and their interaction. Record permanent separation, moving dates and rental periods. The tax legislation contains distinct rules for absence, different homes and relationship-breakdown transfers.
What happens if we sell an investment property or shares instead?
A sale to an outside buyer does not receive relationship-breakdown rollover simply because you intend to divide the proceeds. The owner must consider the normal tax consequences of the sale, including the cost base and applicable concessions. A sale and a transfer to a former spouse can therefore produce different outcomes.
Compare the net proceeds with a proposal that transfers the asset. Identify when the tax event occurs and when tax becomes payable. Retaining enough cash for tax can be as important as agreeing who receives the proceeds at settlement.
Is NSW transfer duty automatically waived after separation?
No. A qualifying property settlement may be exempt, but the NSW duty requirements must be satisfied and documented. They differ from the federal CGT rollover rules. In appropriate marriage or de facto cases, an agreement made to divide property because of separation can support duty relief without being a binding financial agreement.
Revenue NSW specifies the eligible recipients and documents. Do not assume a duty exemption proves CGT rollover eligibility, or vice versa. Your solicitor or conveyancer should arrange the duty assessment and confirm the position before the transfer proceeds.
Does splitting superannuation mean I can withdraw it tax free?
No. Splitting superannuation does not generally release it as spendable cash; preservation and release rules continue to apply. The tax components and type of interest matter, and later benefits are taxed under the relevant rules. A properly implemented split must be distinguished from withdrawing money or transferring an SMSF asset.
The Court explains superannuation splitting. Obtain fund information, consider tax and comply with procedural requirements before finalising orders or agreements. SMSFs, pensions and defined benefits need particular attention; a bank-account balance and a superannuation entitlement are not interchangeable.
Can we choose who declares rent and claims property expenses?
You cannot freely allocate rental income or deductions between you just to reduce tax. For ordinary co-owned investments, allocation generally follows the ownership interests, subject to the applicable rules. Paying the bills yourself or allowing your former partner to collect all the rent does not necessarily change the tax outcome.
Keep rental statements, loan records and expense receipts for the transition period. Ask an accountant to check income and deductions before and after any ownership change. An agreement between the parties does not, by itself, alter the tax law.
Are child support and spousal maintenance taxable?
Ordinary child-support and spousal-maintenance payments are generally not taxable income to the recipient and are not tax deductible to the payer. That does not mean they are ignored for every government calculation. Child support and income-support systems use their own rules, and the nature of an unusual payment should be checked.
Legal Aid NSW explains maintenance taxation. Keep payment records and distinguish support from employment income, business payments or investment returns. Calling a payment maintenance does not settle its tax character if the underlying arrangement is something different.
What should I change in my tax return and government records?
Report your circumstances accurately for the relevant financial year. You may still need spouse details for the period before separation, even if you are no longer together at year end. Changes can affect Medicare calculations, private health insurance rebates and family assistance. Do not simply remove every reference to your former partner.
The ATO explains spouse information. Notify Services Australia where separation affects your payments or child-support assessment, and update contact and bank details securely. Obtain help with separation under one roof or missing information rather than inventing dates or figures.
What additional risks arise with companies and trusts?
Assets owned by a company or held as trustee are not equivalent to personally owned assets. Taking an asset from those arrangements needs separate assessment. CGT, dividend rules and other tax provisions may interact. Family law orders do not automatically neutralise these consequences or guarantee that every receiving structure qualifies for rollover.
The ATO’s ruling on private-company transfers addresses relevant deemed-dividend issues. Identify the correct entity, trustee capacity and recipient in both advice and documents. Get tax advice before substituting a trust or company for the individual named in settlement terms.
How should we allow for tax when negotiating a settlement?
Compare realistic net outcomes rather than assuming equal market values mean equal benefits. Consider deferred tax, sale costs, debts, liquidity and whether a disposal is actually proposed. The 2026 reforms include CGT changes affecting gains accruing from 1 July 2027, so settlement modelling should identify the applicable timing and transition rules rather than using outdated assumptions.
Treasury’s reform timetable makes current advice particularly important. Include provision for exchanging cost-base records and implementing transfers correctly. A hypothetical tax estimate is not automatically a dollar-for-dollar deduction from the property pool; its treatment requires legal and financial assessment.
What does Ellison v Sandini show about implementation?
Ellison v Sandini Pty Ltd [2018] FCAFC 44 demonstrates that settlement documents and the actual recipient matter for CGT rollover. The dispute concerned shares transferred after Family Court consent orders. The Full Federal Court’s majority rejected rollover treatment where the shares went to a corporate trustee rather than the former wife personally.
The orders contemplated a transfer to Ms Ellison and also misdescribed the transferring company’s trustee capacity. At her request, the shares instead went to Wavefront Asset Pty Ltd as trustee. The majority allowed the appeals, set aside the earlier rollover declaration and dismissed the application. The required spouse-as-transferee and connection-to-the-orders conditions were not met. High Court special leave was subsequently refused. This federal tax decision arose in Western Australia and applies nationally. It does not rule out qualifying transfers from a company or trust to a spouse; it shows why the transaction must match the applicable requirements.
How can CM Lawyers help with a tax-aware separation settlement?
CM Lawyers can advise on the legal settlement structure, prepare appropriate documents and coordinate implementation with your tax adviser. Bring ownership records, purchase costs, valuations, loan balances, tax returns and information about companies, trusts and superannuation. Early coordination helps identify assumptions that could change the practical value of the settlement.
I would check the intended recipient and transaction steps before signing, then review implementation against the agreed documents. Discuss your separation arrangements on 02 9557 9000, email lawyers@cmlaw.com.au, or contact CM Lawyers.
