The Australian discount comes after the losses, not before.
Hold a cryptoasset more than twelve months and half the gain is taxed. Simple — until there are losses in the same year, because the method statement in s 102-5(1) applies them first and halves what is left. Do it the other way round and every dollar of loss does half its work. Paste your trades and see both answers.

Halving the gain before subtracting the losses. It is not a rounding difference and it is not conservative: it is wrong in your favour, which is why it survives review.

Parcels are matched first-in-first-out. The ATO permits identifying a specific parcel where your records support it; that is an election with an evidentiary burden, and no tool should make it for you by quietly picking the cheapest one.
Nine countries, and the widest spread is in Denmark
Tracks individual lots, wallet by wallet since Rev. Proc. 2024-28. A long-held gain is taxed at a lower rate; the gain itself is not reduced. What your broker reports →
Pools per asset under s.104 TCGA 1992, but matches same-day and next-30-day acquisitions first. Holding period changes nothing. Work out UK pooling →
Averages every identical property into one adjusted cost base across all your accounts, halves the gain regardless of how long you held it, and denies superficial losses. Work out Canadian ACB →
FIFO parcels, each with its own twelve-month clock; half the gain discounted after losses are applied; the year ends on 30 June; and no wash-sale rule in the CGT provisions, but Part IVA sitting behind it.
The one that breaks every engine built somewhere else: the gain is a fraction of what your whole portfolio cost, sized by its value at the moment of the disposal, so the asset you sold appears nowhere in the arithmetic — and swaps between digital assets are not taxable at all. Work out the French formula →
One average cost per asset across everything held, no schablonmetod — and thirty per cent of every loss simply not deductible, so a year you broke even on is still taxable. Work out the Swedish K4 →
The only place here where the usual bug runs the other way: a deemed acquisition cost of 20 per cent of the sale price — 40 after ten years — taken whenever it beats the real one, so an engine that just does proceeds minus cost overstates the tax. Work out the Finnish deduction →
Changes the question rather than the method: no capital gains tax at all, a deemed return on the value held at 00:00 on 1 January, and a counter-evidence rule whose «actual return» counts unrealised change, allows no costs and cannot go below zero. Work out the Dutch box 3 →
The widest spread of all: a gain is personal income in box 20 at up to 53 %, a loss is a deduction in box 58 worth about 26 %, and as a rule they do not offset each other at all. Work out the Danish boxes →
Harvesting against a discounted gain
There is no Australian wash-sale statute, but there is TA 2008/7 and Part IVA, and there is an arithmetic trap that catches honest filers: a capital loss is applied at full value BEFORE the 50% discount. Harvest a $10,000 loss against a discountable $10,000 gain and you save tax on $5,000, not $10,000 — the loss did half its work. Work out what you are holding at a loss →
Questions
When exactly does the 50% discount apply?
When the CGT event happens at least twelve months after you acquired the asset — section 115-25(1) — and the ATO's working excludes both the day of acquisition and the day of disposal. So a parcel bought on 1 July 2024 and sold on 1 July 2025 is NOT discountable, and the same parcel sold on 2 July 2025 is. One day, half the tax. This page prints the acquisition date, the disposal date and the day count on every line so you can see which side of the line each parcel fell on.
Do losses come off before or after the discount?
Before, and it is the single most valuable thing on this page. The method statement in s 102-5(1) is a numbered list: add up this year's capital gains, subtract this year's capital losses, subtract net capital losses carried forward from earlier years, and ONLY THEN apply the discount to what is left. Halve the gain first and each dollar of loss offsets only fifty cents of gain. The error is always in your favour, which is exactly why nobody catches it.
Can a capital loss be discounted too?
No. Only gains are halved. A capital loss is applied in full, cannot be applied against your salary or other income, and carries forward indefinitely until a capital gain absorbs it (ss 102-10 and 102-15).
I have both discounted and undiscounted gains. Which do my losses hit?
That is your choice, and it is worth money. Applying losses to the gains that are NOT discountable leaves more of the discountable gain to be halved, so the same trades produce a smaller net capital gain. The law permits it; we will not make the election for you. This page reports the conservative order and prints what the election is worth beside it, as a number, so you can decide with your adviser rather than discover it afterwards.
Can one sale be part discounted and part not?
Yes, and this is where a per-sale calculation quietly goes wrong. Sell two coins where one was bought two years ago and one last month, and only the older parcel earns the discount. This page matches parcel by parcel and shows each one, because a single discountable line covering both would halve tax on a parcel that never qualified.
Does Australia have a wash-sale rule?
Not in the CGT provisions, which is precisely why an engine built for the United States says nothing here and why saying nothing is dangerous. The Commissioner published Taxpayer Alert TA 2008/7 on wash sales and applies the general anti-avoidance provision, Part IVA, to arrangements whose dominant purpose is the tax benefit. Selling and rebuying to crystallise a loss is exactly the arrangement it describes.
What about the personal use asset exemption?
A capital gain on a personal use asset acquired for $10,000 or less is disregarded under s 118-10(3). Two conditions, and we can only see one of them: the cost is arithmetic, the «kept or used mainly for personal use» half is a fact about how you actually used the thing. The ATO's position is that cryptoassets are rarely personal use assets and that holding for investment is not personal use. So this page never applies the exemption. It counts the parcels that pass the cost test and leaves the question with you.
Which financial year is a December sale in?
The one ending the following 30 June. The Australian year runs 1 July to 30 June, so a sale on 15 December 2025 belongs to the 2025–26 year. A tool that splits your history by calendar year does not produce a slightly different Australian answer — it reports a different set of transactions, and no amount of correct arithmetic afterwards recovers from that.
What about indexation?
It does not arise. The indexation method is available only for assets acquired before 21 September 1999, and no cryptoasset was. It is mentioned so you can see it was considered rather than forgotten.
