Dr Anya Sharma is considering selling her stake in a Castle Medical partnership in Sydney. The proposed exit could release substantial capital, but the important question isn't whether a capital gain exists. It's which disposal choices, exemptions, holding periods and timing decisions may reduce the future CGT liability without creating a larger commercial or compliance problem.

A Decision Many Australians Eventually Face
A large asset sale deserves more than a last-minute tax calculation. The right result may depend on whether the asset is a family home, an investment, an active business asset, a trust investment or an interest held by someone whose Australian tax residency has changed.
The practical answer to how to minimise capital gains tax is to work through the rules in the correct order. Start with exemptions and rollovers, confirm the holding period, identify available small business concessions, apply losses correctly, and then test the disposal date against the incoming regime described by the Australian Taxation Office.
For property owners, a separate capital gains tax property Australia guide may help explain the broader property context, but the ATO rules remain the authority for your return. Everglow's taxation on property sale guidance can also help frame the records and decisions that need attention before a contract is signed.
Stewardship principle: The aim isn't to chase a tax outcome in isolation. It's to preserve after-tax wealth while keeping the transaction commercially sensible and properly documented.
Dr Sharma's decision may involve the general discount, a business concession, capital losses, superannuation planning and the interaction between current rules and the proposed 1 July 2027 changes. Residency and ownership structure may alter the result again. This is general information, not personal tax, financial or legal advice.
The Four-Step CGT Workflow Before Any Discount
The Australian Taxation Office (ATO) calculation starts before the discount. A taxpayer must establish what happened, when it happened and whether an exemption or rollover applies.

Start with the acquisition date
Dr Sharma should locate the original agreement, settlement evidence and records supporting the cost base. Depending on the asset, that may include acquisition expenses, improvements and disposal costs. Missing records can make a defensible calculation harder, particularly where the asset has been held for years or moved between structures.
Next, identify the CGT event. A sale contract commonly triggers the relevant event for property, while other assets may have different events and dates. The contract date, rather than settlement alone, may be decisive, so the documentation needs to be reviewed carefully.
Test relief before applying the discount
The third step is to ask whether the asset or transaction qualifies for an exemption or rollover. A main residence exemption, business rollover or another statutory relief may be more valuable than a discount applied to a taxable gain.
Only after those tests should Dr Sharma examine the general discount. An Australian resident individual who has owned an eligible asset for at least 12 months may generally reduce the capital gain by 50%, subject to the ATO's conditions and calculation method, as set out in its CGT discount guidance. Disposing even one day too early may mean the discount isn't available.
Investors with digital assets should keep transaction histories, wallet records and acquisition evidence. A specialist overview of crypto tax strategies for investors may be useful background, but Australian tax treatment still depends on the facts and the nature of the activity.
A structured capital gains tax strategy review should complete the workflow before the sale becomes unconditional.
The Two Largest Exemptions in the System
The general discount and the main residence exemption solve different problems. The discount reduces an eligible taxable gain. The main residence exemption may remove the gain altogether when the statutory conditions are satisfied.
An Australian resident individual who holds an eligible asset for at least 12 months may generally apply the 50% CGT discount after other CGT steps, including the use of capital losses. The main residence exemption is potentially broader, but it depends on the dwelling's use, ownership facts and land area. The ATO states that a qualifying Australian home used as the owner's residence, not used to produce income or for profit-making activity, and situated on land of 2 hectares or less, may be exempt from CGT.
| Feature | 50% CGT Discount | Main Residence Exemption |
|---|---|---|
| Core benefit | Reduces an eligible individual's net capital gain by half | May remove the qualifying gain entirely |
| Typical asset | Shares, investment assets and eligible business assets | The owner's qualifying home |
| Main condition | At least 12 months of ownership | Residence and use conditions must be met |
| Important risk | Sale before the holding period is complete | Income-producing use or other facts may restrict the exemption |
| Planning focus | Disposal date and gain calculation | Occupancy, use, land and absence history |
A former home can sometimes continue to receive main residence treatment after the owner moves out and rents it. The ATO permits the owner to keep treating it as their main residence for up to 6 years during an income-producing absence, subject to the applicable conditions and the treatment of separate absences. The main residence exemption and 6-year rule needs to be assessed against the full ownership history.
Property owners should be cautious where part of the home is used for business, where the property has been acquired for flipping, or where another dwelling is treated as the main residence. The exemption is not a simple label attached to every home sale.
Small Business CGT Concessions in the Right Order
Small business concessions may provide a more substantial result than the general discount, but they're available only when each statutory test is satisfied. For an active business asset, business.gov.au describes a 50% active asset reduction, a lifetime retirement exemption up to $500,000, a 15-year exemption for qualifying owners aged 55 or over who are retiring or permanently incapacitated, and rollover relief that may defer a gain when replacement-asset requirements are met.
The sequence matters. First test whether the asset is active and whether the ownership and small business conditions are satisfied. Then consider the 15-year exemption where it applies, the active asset reduction, the retirement exemption and rollover options. The ATO's CGT asset and exemption guidance should be read with the facts of the entity and its connected parties.
For Castle Medical, Dr Sharma may need to examine the partnership interest, the underlying business assets, her period of ownership and whether she remains an owner at the time of the CGT event. The outcome may differ materially from the sale of a passive investment. A concession stack can potentially eliminate a gain in some circumstances, but the result can't be assumed from the size of the gain alone.
Common failure points include poor evidence of active-asset use, an incomplete analysis of connected entities and affiliates, a missed replacement-asset condition, or failure to make the required retirement exemption election. Dr Sharma should also align the disposal with her genuine retirement intentions, rather than choosing a financial year solely because it appears convenient.
Everglow's capital gains tax exemptions guidance may help identify which questions need to go to a tax adviser before negotiations progress.

Timing Strategies Around the 1 July 2027 Rule Change
Selling before 30 June 2027 may be sensible only if the proposed transition is enacted and the commercial case supports the decision. Under the Government's proposed reforms for gains accruing from 1 July 2027, subject to passage of legislation, the ATO describes a replacement for the current 50% CGT discount involving cost base indexation and a 30% minimum tax rate, with the new treatment applying to gains accruing after that date. The ATO's proposed CGT reform guidance should be checked before acting.
Existing assets may need to be apportioned between the pre-change and post-change periods. A rushed disposal could crystallise tax and transaction costs while giving up future indexation benefits. Holding the asset and measuring the gain may produce a better result where there is no independent commercial reason to sell.
| Scenario | Pre-1 July 2027, 50% CGT discount | Post-1 July 2027, indexation plus standard rates |
|---|---|---|
| Asset sold before the proposed change | Eligible gain may receive the current discount | Not applicable |
| Asset held across the proposed change | Not applicable to a completed pre-change sale | Gain may require pre- and post-change apportionment |
| Main planning question | Is the 12-month condition met? | How much gain accrued in each period, and what indexation applies? |
For Dr Sharma, a stated $800,000 gain on a sale before the proposed 30 June 2027 transition date may fall under the current framework if the legislation is enacted and the other conditions are met. The same asset sold on 1 August 2027 may require apportionment and review of indexation under the proposed treatment. The comparison depends on the cost base, acquisition date, valuation method, entity, residency and final legislation.
Use planning with pro forma projections to compare disposal dates and outcomes, then verify the assumptions against current legislation and ATO guidance. Spreading separate disposals across income years may help, depending on the assets and available losses. Do not sell solely to meet a proposed date unless the commercial reasoning and tax analysis support it.
The current CGT discount framework remains relevant to disposals under existing rules. Review significant decisions close to completion, because proposed legislation and administrative guidance may change.
Capital Losses, Trust Distributions and Sequencing
Capital losses can reduce capital gains, but they can't generally reduce salary, wages or other assessable income. The ATO permits current-year losses to be applied against current-year gains, while prior-year net capital losses may be carried forward indefinitely for future capital gains. Losses must be applied in the order required by the ATO, and the discount is considered after the relevant losses have been applied.
That ordering creates two practical strategies. A taxpayer expecting a gain may review whether an existing loss can be realised in the same income year. Alternatively, several disposals may be coordinated so losses are used against gains rather than carried forward unnecessarily. The decision must account for investment fundamentals, transaction costs and the possibility that selling a loss-making asset changes the portfolio risk.
Trusts require a separate review. A trust may distribute a capital gain to a beneficiary who is presently entitled under the deed and tax rules, but the trustee must confirm the deed, resolutions and streaming requirements. An eligible discounted gain may retain its character as it flows to an individual beneficiary. A corporate beneficiary generally can't claim the individual 50% discount in the same way.
Family trust distributions also need attention where minors, related entities or section 102 issues are involved. A trustee shouldn't assume that directing a gain to a lower-tax beneficiary produces the intended result. Before finalising distributions, confirm the trust deed, beneficiary entitlement, resolutions, carried-forward losses and the character of the gain.
Residency, Super and Records That Keep the Outcome
Residency can change the tax result, particularly where an asset spans an Australian residency change. A non-resident should obtain advice before disposal because the relevant CGT event, asset type and residence history matter. Main residence treatment may be restricted or apportioned where ownership continues through a change in residency, so a former home shouldn't be assessed from occupancy alone.
Trust distribution planning also needs discipline. A trustee may be able to stream a capital gain to a particular beneficiary where the deed and tax rules support that treatment. The family should consider whether the beneficiary has capital losses, other income, residency issues or an entity structure that changes the benefit. A company and an individual beneficiary don't necessarily receive the same result.
Superannuation may form part of the wider cashflow plan, but it isn't a substitute for CGT analysis. Concessional and non-concessional contributions may interact with assessable income and available contribution capacity. Exceeding the relevant caps can create additional tax, so contributions should be checked before implementation and coordinated with the broader retirement strategy.
Keep the evidence from acquisition
The ATO's recordkeeping expectations make early organisation worthwhile. Keep the acquisition contract, settlement documents, improvement invoices, valuation reports, disposal costs and any rollover or exemption documentation. Records should support the cost base and the dates used in the calculation.
The ATO property CGT guidance confirms the practical order for property calculations. After determining the gain and applying capital losses, an individual or trust generally applies the 50% discount to the remaining eligible gain where the ownership period is at least 12 months.
A complete plan generally tests exemptions first, then concessions and the general discount, then losses and broader income or superannuation decisions. The correct order depends on the taxpayer's residency, asset mix, trust deed, superannuation position and family income profile.
Records matter most when the transaction is old, complex or disputed. A bank statement showing a payment isn't always enough to prove what the payment represented.
Specialist advice is appropriate where the asset is held through a company or trust, a rollover is contemplated, the sale involves a business, the property has mixed use, or the ATO's compliance guidance raises a risk issue. SMSF trustees, foreign residents and people with multiple entities should obtain advice before signing.
Frequently asked questions
Does the CGT discount apply to inherited assets?
An inherited asset isn't automatically entitled to the discount merely because the previous owner held it for a long time. The beneficiary's acquisition date and the special inheritance rules need to be reviewed, along with the period the beneficiary owns the asset before disposal. The ATO's factsheet should be checked before relying on a 12-month conclusion.
How are cryptocurrency gains treated?
Cryptocurrency may be treated differently depending on whether the activity is investment, business or another form of dealing. Keep records of acquisition, disposal, transfers and costs. The tax result depends on the facts, so a person shouldn't apply the general investment approach without reviewing the nature of the transactions.
What happens when an asset is partly used for investment?
A depreciating asset or property used partly to produce income may require an allocation between private and income-producing use. The main residence exemption may be reduced where income-producing use applies. The calculation should reflect the actual periods and use, supported by contemporaneous records.
Can capital losses reduce salary income?
No. Capital losses are generally applied against capital gains, not salary or wages. Unused net capital losses may be carried forward indefinitely to offset future capital gains, subject to the applicable rules and recordkeeping requirements.
Should I sell before 1 July 2027?
Not automatically. The answer may depend on the current discount, the gain accrued before and after the change, possible indexation, transaction costs, commercial objectives and the final law. A documented comparison is more reliable than a date-driven sale.
The core answer is to identify exemptions and concessions first, protect the 12-month holding period where appropriate, apply losses in the correct order and model any disposal that spans the 1 July 2027 transition. The right approach depends on your residency, ownership structure, asset history, income and commercial objectives.
