The CGT 12-Month Discount for Crypto in Australia: How the 50% Rule Works
Of all the levers an Australian crypto investor can pull to reduce their tax bill legitimately, the capital gains tax (CGT) 12-month discount is the biggest and the simplest. Hold a crypto asset for more than 12 months before you sell it, and as an individual you may only pay tax on half the capital gain. Sell a day too early, and the full gain is taxable. For a large position, that difference can be thousands of dollars.
Yet this rule is widely misunderstood. Many investors assume it means “half the tax”, or that swapping one coin for another resets nothing, or that the discount applies inside a company or SMSF the same way it does for an individual. This guide explains exactly how the 50% CGT discount works for cryptocurrency under current ATO guidance, walks through the calculations with real AUD figures, and shows you how to make sure you actually qualify.
How the ATO taxes crypto: the basics
For most Australians, the ATO treats cryptocurrency as a CGT asset, not as money. That means a taxable event — a “disposal” — happens whenever you sell crypto for AUD, swap one crypto for another, spend it on goods or services, or gift it. Your capital gain is broadly the disposal proceeds (in AUD) less your cost base (what you paid, plus certain incidental costs such as brokerage or transaction fees).
That net capital gain is added to your assessable income and taxed at your marginal rate. If you want the full picture of how disposals, income and DeFi all fit together, our complete guide to crypto tax in Australia is the place to start, and our overview of crypto tax and regulation in Australia sets the wider context. This article zooms in on the single most valuable concession within that system.
What the 50% CGT discount actually is
If you are an Australian-resident individual and you hold a CGT asset for more than 12 months before disposing of it, you are generally entitled to reduce the resulting capital gain by 50%. In practice that means only half of the gain is added to your taxable income — it is a discount on the gain, not a flat halving of your tax bill.
A simplified illustration: suppose you buy some crypto for $10,000 and later sell it for $30,000, producing a $20,000 gain. Held for 11 months, the full $20,000 is added to your income. Held for 13 months, only $10,000 is — the other $10,000 is discounted away. You are then taxed on that reduced amount at your marginal rate. This is why timing a sale even a few days past the 12-month mark can be so consequential, and it is a core consideration when taking profits in crypto.
A full worked CGT calculation with numbers
Let us make it concrete. Meet Daniel, an Australian resident with a salary of $110,000, which places his top slice of income in the 37% marginal bracket (plus the 2% Medicare levy). On 3 March 2025 he buys 2 ETH for a total of $8,000, paying a $40 brokerage fee, so his cost base is $8,040.
Scenario A — sells before 12 months. On 1 February 2026 (about 11 months later) he sells the 2 ETH for $20,000, paying a $60 fee. His proceeds are $19,940 and his capital gain is $19,940 − $8,040 = $11,900. Because he held for less than 12 months, no discount applies. The full $11,900 is added to his income and taxed at 39% (37% + 2%), a tax cost of roughly $4,641.
Scenario B — waits past 12 months. He instead sells on 10 March 2026, more than 12 months after acquisition. Same figures, same $11,900 gain — but now the 50% discount applies, halving the assessable gain to $5,950. Taxed at 39%, the cost is roughly $2,321. By waiting a few extra weeks, Daniel saves about $2,320 in tax on the identical sale.
Now add a capital loss to show the order of operations. Say Daniel also sold a different coin during the same year at a $3,000 loss. That loss is applied to his gain before the discount: $11,900 − $3,000 = $8,900, then the 50% discount gives an assessable gain of $4,450. The sequence — losses first, discount second — is not optional, and getting it right matters.
Counting the 12 months correctly
The detail that trips people up is when the clock starts and stops. The ATO measures the holding period from the day after you acquired the asset up to the day of the CGT event (the disposal). You must hold for more than 12 months — exactly 12 months is not enough. If there is any doubt, waiting an extra few days to be safely past the anniversary is cheap insurance.
A concrete example: if you acquire crypto on 15 June 2025, the clock starts on 16 June 2025, and you must not dispose of it until at least 16 June 2026 for the discount to apply. A sale on 15 June 2026 — exactly 12 months — misses out.
Two common misconceptions:
- Swapping resets the clock. If you trade Bitcoin for Ethereum after 10 months, that swap is a disposal of the Bitcoin, and your Ethereum then starts its own new 12-month clock from the swap date. Crypto-to-crypto trades constantly reset holding periods, and each swap is also a taxable disposal in its own right.
- Parcels are counted separately. If you bought crypto in several tranches — for example by dollar-cost averaging — each parcel has its own acquisition date. When you sell, which parcels you are treated as disposing of affects both your gain and your discount eligibility, so identifying parcels correctly matters.
Which parcel do you sell? Choosing a cost-base method
Because DCA leaves you with many parcels bought at different prices and dates, you get to choose which parcels a sale draws from, provided you can specifically identify them in your records. The ATO accepts methods such as first-in-first-out (FIFO), or specifically identifying particular parcels. This choice is a genuine planning tool: selling an older parcel might secure the 50% discount, while selling a higher-cost parcel might reduce the raw gain. For example, if you hold a 14-month-old parcel bought at $30,000 and a 3-month-old parcel bought at $55,000, selling the older one qualifies for the discount, while selling the newer one produces a smaller gain but no discount. You must apply your chosen method consistently and keep records that support it.
Capital losses come first
Order of operations matters, as the worked example above showed. You apply any capital losses (from the current year or carried forward from prior years) against your capital gains before applying the 50% discount. Because the discount only reduces what remains, it is generally most efficient to offset losses against gains that are not discount-eligible first, preserving more of your discounted gains. This kind of planning — sometimes involving deliberately realising a loss in the same financial year to offset a large winner — is where a registered tax agent earns their fee. Capital losses that exceed your gains in a year are not lost: they carry forward indefinitely to offset future capital gains.
Who does NOT get the discount
The 50% discount is not universal. Key limits to be aware of:
- Companies do not receive the CGT discount at all. If you hold crypto through a company, gains are taxed without the 50% reduction (though the company tax rate itself differs from personal rates).
- Traders, not investors. If the ATO considers you to be carrying on a business of trading crypto, your crypto is treated as trading stock and gains are ordinary income — the CGT rules, and therefore the discount, do not apply at all. The line between investor and trader depends on your activity, intention, frequency, organisation and scale, not on how you label yourself.
- SMSFs get a reduced discount. A complying self-managed super fund holding an asset for over 12 months generally gets a one-third discount, not 50%. If you are considering crypto inside an SMSF, the rules differ meaningfully and the compliance burden is higher.
- Non-residents face restrictions on accessing the discount for the period they were not Australian residents, and the calculation can be apportioned.
Does the discount apply to staking, airdrops and DeFi rewards?
This is a subtle but important point. Rewards from staking and many airdrops are generally treated as ordinary income at the AUD value when you receive them — the CGT discount does not apply to that income. However, the tokens you receive then have a cost base equal to that value, and a fresh 12-month clock starts from the date you received them. If you later sell those tokens for more than that value, the subsequent gain can qualify for the 50% discount if you have held them for more than 12 months. In other words, the reward itself is income now, but the future growth on it can be discountable capital gain later.
What about the “personal use asset” idea?
You may hear that crypto can be a “personal use asset” and therefore CGT-free. Be very careful here, because the ATO applies this narrowly. Crypto is generally only a personal use asset where it was acquired and used within a short period to buy items for personal use or consumption — and even then, the exemption only applies where the cost of the crypto was $10,000 or less. Crypto acquired and held as an investment, or used to make a profit, is not a personal use asset, regardless of what you eventually spend it on. In practice, the overwhelming majority of Australian crypto holdings are investments and fall squarely under the normal CGT rules described above, so treat any claim that your investment gains are “personal use” and tax-free with real caution.
Timing sales around the financial year and your income
Because a capital gain is added to your assessable income for the year of the disposal, when you sell can matter almost as much as whether you qualify for the discount. Two practical levers, both entirely legitimate:
- Spread large disposals across financial years. Selling part of a big position before 30 June and part after 1 July splits the gain across two income years, which can keep you out of the top marginal bracket in either year.
- Sell in a lower-income year where possible. If you know a year will have unusually low income — a career break, parental leave, or retirement — realising gains then can mean they are taxed at a lower marginal rate, and the discount still applies on top.
These are general considerations, not a substitute for advice tailored to your numbers, but they show why a disciplined approach to taking profits and the CGT discount go hand in hand.
Records are everything
You cannot prove a holding period — or claim the discount — without records. For every parcel you need the acquisition date, the AUD value at acquisition, associated fees, and the same details on disposal. The ATO expects you to keep these records for at least five years after a disposal, and it receives data-matching information directly from Australian exchanges, so accuracy matters and discrepancies get noticed. Our guide to the records every Australian crypto investor must keep covers this in detail, and dedicated software such as Koinly or CryptoTaxCalculator will track holding periods and apply the discount automatically across hundreds of transactions.
Frequently asked questions
Does the 12-month clock reset if I swap one coin for another?
Yes. A crypto-to-crypto swap is a disposal of the first asset and an acquisition of the second. Your holding period for the new coin starts from the swap date, even though you never converted to AUD, and the swap itself is a taxable event.
Is exactly 12 months enough to get the discount?
No. You must hold the asset for more than 12 months, counted from the day after acquisition to the day of disposal. Holding for exactly 365 days does not qualify, so it is wise to wait a few extra days past the anniversary to be safe.
Do I get the 50% discount inside an SMSF or company?
No to companies, which get no CGT discount. An SMSF that qualifies generally receives a one-third discount rather than 50%. The full 50% individual discount applies to Australian-resident individuals (and certain trusts). Always confirm your situation with a registered tax agent.
How is the discount calculated if I have capital losses too?
Apply your capital losses to your capital gains first, then apply the 50% discount to what remains of the discount-eligible gain. For example, a $10,000 discount-eligible gain reduced by a $4,000 loss leaves $6,000, and the 50% discount then gives an assessable gain of $3,000. Losses always come before the discount.
Does the CGT discount apply to my staking rewards?
Not to the reward itself. Staking rewards are generally ordinary income at their AUD value when received, with no discount. But those tokens then start their own 12-month clock, so any later gain on their value can qualify for the 50% discount if you hold them for more than 12 months before selling.
