The quick answer
Start here
Sale proceeds are not the same as a capital gain. Build the parcel and cost records first, then apply the rules for the relevant year. Announced changes from July 2027 make undated tax shortcuts particularly unreliable.
A share sale creates several different numbers
If $15,000 arrives after an investment sale, it is easy to describe the entire receipt as profit. That confuses the money returned from your original investment with the gain or loss. Start with the disposal proceeds, the relevant acquisition parcel and the applicable cost records. Only then can a tax calculation become meaningful.
This is also a retirement-planning issue. Selling an investment to cover spending can involve a mixture of original capital and gain, with a possible future tax bill. A flat assumption that every withdrawal is taxed like salary is usually too crude, but assuming sales never produce tax is equally unhelpful. The practical task is a documented estimate that a registered tax agent can check, rather than an invented universal withdrawal tax rate.
A fictional sale calculation before concessions
Imagine a fictional share parcel bought for $10,000 with $20 acquisition brokerage. It is later sold for $13,000 with $25 sale brokerage. For this simplified example, assume the acquisition brokerage is included in a $10,020 cost base and the disposal cost is treated consistently, giving a $2,955 gain before any available losses, discount or other adjustment.
Do not deduct the $25 twice by both reducing proceeds and adding it again elsewhere. The point is to reconcile each expense once. The example deliberately excludes currency conversion, corporate actions, fund cost-base adjustments and special tax rules. Your platform's displayed profit may use a different convention, so a useful review starts with transaction confirmations and the tax treatment of each item, not a screenshot of an account performance tile.
Identify the actual parcel sold
Repeated purchases create multiple parcels with different acquisition dates and costs. A holding of 200 units does not necessarily have one tax history. Reinvestment plans, transfers and corporate actions can add further records. Selling only part of a holding requires an appropriate, supportable identification of the units disposed of.
Make a parcel register with date, quantity, price, acquisition costs and later adjustments. Keep quantity movements separate from market value movements. Moving investments between platforms does not justify resetting every acquisition price to the transfer-day value. Ask for the original transaction history before closing an account, and preserve evidence of how a sale was allocated. A neat spreadsheet is helpful only when its entries can be traced back to reliable documents.
Capital losses are a different bucket from wages
The current capital-gains framework distinguishes capital losses from deductions against ordinary salary. Capital losses generally offset capital gains rather than wages, and unused net capital losses may be carried forward subject to the rules. A decline shown in an unsold portfolio is not automatically a realised capital loss available for a tax return.
For a fictional simple ledger, a $2,955 gain and an allowable $955 capital loss leave $2,000 before any later applicable treatment. Keep that loss record until its use is properly documented; its value does not disappear merely because it was not useful in the year it arose. The treatment of losses can depend on the asset and circumstances. Do not sell solely to manufacture a tax outcome without considering anti-avoidance rules, transaction costs and the investment decision itself.

Read tax dates instead of repeating an old shortcut
As checked on 25 October 2026, Treasury's Budget 2026–27 page announces changes from 1 July 2027 to the capital-gains tax arrangements, including replacing the existing 50% discount with inflation-based arrangements for relevant future gains. It describes transition distinctions. That announcement is not a substitute for checking enacted law and detailed ATO guidance when a disposal occurs.
This article therefore does not label every long-held investment sale as automatically eligible for a permanent 50% discount. The existing framework also contains eligibility, residency, holding-period and asset-specific conditions. Keep the sale date, acquisition date and relevant financial year visible. A tax estimate for an earlier completed year should not be silently reused for a later sale after the rules or personal circumstances have changed.
Why the order of the calculation matters
Under the existing framework, losses are applied before a relevant discount to remaining eligible gains. To illustrate only that ordering, assume a qualifying gain of $10,000, an available $2,000 loss and a hypothetical 50% discount applying to the remainder. The result is $4,000: ($10,000 minus $2,000) multiplied by 50%. Discounting first and subtracting the loss would incorrectly produce $3,000 in that illustration.
This is a deliberately dated framework example, not a statement that the same discount will apply to a future sale. Where gains have different eligibility, allocation choices can also matter. A mixed portfolio with current-year gains, carried-forward losses and fund distributions needs a complete calculation. Take the full set of records to the tax review rather than calculating each holding independently and adding inconsistent answers.

Make a tax reserve a separate planning line
Suppose a household sells $13,000 of investments and intends to spend $12,000. The apparent $1,000 spare cash is not necessarily the correct tax reserve. Tax depends on the gain, other capital events and the person's assessment, not merely the proceeds left after shopping. Obtain a suitable estimate and label the reserve as provisional until the position is clear.
The Freedom Clock does not calculate parcel-level CGT, personal tax brackets or future legislative transitions. Use a defensible after-tax return or spending assumption for scenario work and retain the separate tax estimate. If a spending plan depends on selling assets, note which pool can actually be accessed and what records explain its cost. A portfolio balance alone is not a detailed after-tax cash-flow plan.
A year-end sale file that remains usable
Keep purchase and sale confirmations, relevant registry statements, ownership details, corporate-action notices, cost-base adjustments and prior loss schedules together. Add a short explanation of any allocation or estimate used. The ATO's record guidance notes that records can be needed after the event and that carried-forward losses can extend the practical retention requirement.
Before relying on prefilled information, check quantities and transactions against your own records. A platform may not know about an earlier broker, an overseas holding or an adjustment reported separately by a fund. Where something is missing, mark it unresolved and retrieve the evidence. That is better than substituting zero acquisition cost or choosing a convenient date simply to finish the worksheet quickly.
Separate the trade date from the bank movement
A sale can have an order date, execution date, settlement date and later bank-withdrawal date. They describe different events. Preserve the trade confirmation and check the relevant tax timing rule rather than assigning the sale to whichever financial year contains the bank deposit. Near 30 June, that distinction can matter materially.
A cancelled order should not be recorded as a completed disposal, while a partial execution should not be ignored because the full order never finished. Match actual quantities against confirmations, then reconcile the remaining holding. This keeps the tax worksheet connected to the investment register and avoids accidentally allocating the same acquisition parcel to more than one sale.
FAQ: Is the cash from selling shares all taxable income?
No. Proceeds and gains are different. The gain or loss depends on the relevant cost and disposal records, then the applicable tax rules. Some transactions have special treatment, so the simple difference shown in a trading app may not be the final tax figure.
FAQ: Can a capital loss reduce my salary tax?
Generally a capital loss offsets capital gains rather than wages. Unused net capital losses may be carried forward under the rules. Retain the supporting records and check asset-specific restrictions. A fall in the value of an investment you still hold is not automatically a realised loss.
FAQ: Does holding shares for a year always halve the tax?
No. A discount is not a promise to halve your entire tax bill, and eligibility conditions matter. Treasury has also announced changes from July 2027. Check the applicable law and ATO guidance for the actual disposal year rather than relying on a timeless headline.
FAQ: Does Elaris calculate my capital gains tax?
No. The projection does not reconstruct parcels, assess deductions, apply losses or determine future tax-law transitions. Keep a separate tax estimate, use consistent after-tax assumptions and obtain individual help where the result affects a significant sale or retirement decision.
