If you offset your crypto losses properly, you could save up to AUD 4,500 in capital gains tax on AUD 15,000 of gains if you’re in a 30% marginal tax bracket.
In Australia, capital losses can offset capital gains, which means a losing crypto investment could actually help reduce your tax bill.
So, how can you strategically use crypto losses to lower your capital gains tax?
In this guide, we’ll walk you through how tax loss harvesting works in Australia, the rules you must follow, key deadlines, and how to avoid penalties.
Key Takeaways
- Tax-loss harvesting lets you use crypto losses to offset capital gains.
- There is no fixed limit on eligible losses you can harvest.
- Unused harvested losses can reduce future capital gains.
- Only realised, eligible losses can be harvested.
- The timing and purpose of the disposal matter.
What Is Tax Loss Harvesting in Crypto?
Tax loss harvesting, also called tax loss selling, refers to the practice of selling a crypto asset that has decreased in value to intentionally realise a capital loss. This realised loss can then be used to offset any realised capital gains you’ve made during the same financial year.
If you have no gains that year, the loss can be carried forward to reduce future gains. It’s a legal, ATO-compliant strategy used by many savvy investors to reduce their taxable income under CGT rules.

How Does Tax Loss Harvesting Work for Crypto Assets in Australia?
Tax loss harvesting works particularly well for crypto because of its volatility.
How Does It Work?
Suppose you bought Bitcoin for AUD 20,000 and later sold it for AUD 12,000. You have realised an AUD 8,000 capital loss.
During the same financial year, you also sold another crypto asset and made an AUD 20,000 capital gain.
Your calculation would look like this:
AUD 20,000 capital gain − AUD 8,000 capital loss = AUD 12,000 net capital gain
Instead of having AUD 20,000 in capital gains before applying any other CGT rules, you now have AUD 12,000 remaining.
The process only works for realised losses, so just holding a declining asset won’t help. You must dispose of the asset through selling, swapping, or using it in a transaction to trigger the CGT event.
The Order Of Offset Matters
Australia’s CGT rules don’t simply let you subtract losses from whichever gains you want and then apply the CGT discount. Capital losses are applied before the CGT discount.
For example, assume you have:
- AUD 10,000 of a capital gain that is not eligible for the CGT discount
- AUD 10,000 of a capital gain eligible for the 50% CGT discount
- AUD 10,000 of capital losses
You can generally apply the loss to the non-discounted gain first. That brings the non-discounted gain to zero, leaving the discounted gain untouched. The 50% CGT discount can then be applied to the remaining AUD 10,000 gain, leaving AUD 5,000 as the discounted capital gain.
The ATO specifically recommends considering this order because applying losses to gains that cannot receive the CGT discount can produce a lower net capital gain.
How Does Tax Loss Harvesting Help Australians?
Tax loss harvesting can turn a losing crypto investment into a way to reduce the tax you pay on gains you’ve already made.
But the benefit isn’t limited to the current year:
- You can offset gains from other CGT assets: The loss does not have to come from the same cryptocurrency that generated the gain. An eligible crypto capital loss can generally be used when calculating your net capital gain across your CGT assets.
- You can carry unused losses forward: If you have AUD 20,000 in capital losses but only AUD 8,000 in capital gains, the remaining AUD 12,000 net capital loss can generally be carried forward to future years.
- You can make losses useful during a market downturn: A portfolio loss does not have to be purely negative from a tax perspective. If you were already considering disposing of an underperforming asset, realising the loss can potentially reduce gains elsewhere.
- You can preserve eligible CGT discounts: For individuals, the 50% CGT discount may apply to eligible assets held for at least 12 months. Because capital losses are applied before the CGT discount, the way losses are applied can affect your final taxable capital gain.
However, the actual tax saving depends on your marginal tax rate and other CGT circumstances.
When Can You Use Capital Losses for Tax Loss Harvesting?
Capital losses must be applied in the same financial year in which they are incurred, provided you also have capital gains. If you sell one crypto asset at a loss and another at a profit, you must offset the loss against the gain before calculating your net tax liability. This reduces the overall capital gains subject to tax and can lower your tax bill significantly in the current year.
You Can Use Losses When:
- You have capital gains in the same financial year: An eligible capital loss can reduce your capital gains when calculating your net capital gain.
- You have gains from other CGT assets: The gain and loss do not necessarily have to come from the same cryptocurrency. Capital losses can generally be used against eligible capital gains from other CGT assets.
- Your losses are larger than your gains: If your losses exceed your capital gains, the unused amount becomes a net capital loss that can generally be carried forward to future income years.
- You realise the loss before the financial year ends: To count toward a particular financial year’s tax position, the relevant CGT event must occur in that financial year. In Australia, the income year generally ends on 30 June.
When Can't You Use the Loss?
You cannot use a net capital loss to reduce your salary, wages, or other ordinary income. You also cannot automatically claim every crypto-related loss; assets and transactions subject to different CGT treatment, such as certain personal-use assets, have specific rules.
For example, if you have AUD 5,000 in salary income and AUD 10,000 in net capital losses, you cannot deduct the AUD 10,000 loss from your salary. The loss is instead carried forward to offset eligible capital gains in a future year.
Wash Sale Rules by ATO: What to Avoid?
A wash sale happens when an investor sells a crypto asset at a loss and then repurchases the same (or a substantially similar) asset shortly after. The intent is to trigger a capital loss without really changing the investment position. This strategy creates a “paper loss” and undermines the integrity of genuine tax loss harvesting and can come under ATO scrutiny.
Australia does not have a specific 30-day or 60-day wash-sale rule for crypto. However, the ATO can apply the general anti-avoidance provisions where transactions are structured primarily to obtain a tax benefit.
Can You Sell Crypto at a Loss and Buy It Back?
Selling a crypto asset at a loss and then buying the same or a similar asset again may attract scrutiny if the arrangement is designed mainly to create an artificial capital loss while allowing you to maintain substantially the same investment position.
The key issue is not simply how many days pass between the sale and repurchase. The purpose and circumstances of the transactions can matter when determining whether the arrangement is an acceptable capital-loss transaction or an arrangement intended to obtain a tax benefit.
How to Avoid Problems With Crypto Loss Harvesting
If you realise a crypto capital loss, keep clear records showing:
- The date and value of the original purchase
- The date and value of the disposal
- The reason for selling the asset
- Details of any subsequent purchase of the same or another crypto asset
- Transaction records from exchanges and wallets
Avoid treating a loss as automatically deductible simply because you sold an asset below its purchase price. If the transaction was entered into primarily to obtain a tax benefit, the ATO’s anti-avoidance rules may need to be considered.

Key Deadlines for Tax Loss Harvesting in 2026
Timing is everything for crypto tax loss harvesting in Australia. To ensure your realised losses count toward reducing your tax liability for the 2025–26 financial year, you must finalise all disposals before the end of the tax year. Missing these deadlines could mean waiting another year to benefit from your capital losses.
Here are the important dates to remember:
- June 30, 2026 – Last day to sell crypto assets at a loss to include them in your 2025–26 tax return.
- October 31, 2026 – Deadline to file your individual tax return if lodging on your own.
- May 15, 2027 – Extended deadline for tax agents or accountants to file your return if you’re registered with them before October 31.
Benefits and Risks of Crypto Tax Loss Harvesting
While tax loss harvesting can offer significant advantages for Australian crypto investors, it’s not without its trade-offs. Below, we break down the key benefits and risks you should consider before using this strategy.
Benefits of Tax Loss Harvesting
- Reduces Taxable Capital Gains: Harvesting assets at a loss allows you to offset gains from other crypto disposals, directly reducing the amount of Capital Gains Tax (CGT) you owe.
- Carries Forward Future Savings: If you don’t have any capital gains in the current year, the losses can be carried forward indefinitely and used to reduce tax in future years.
- Improves Portfolio Performance: Harvesting losses encourages a review of poor-performing assets, helping you exit weak positions and reallocate to stronger investments.
- Legal and ATO-Approved: When done correctly and without triggering wash sale rules, tax loss harvesting is a completely legal and recognised strategy under Australian tax law.
- Maximises Low-Income Years: Harvesting in years when you have a lower income can help you minimise the CGT rate on any residual gains, combining well with loss harvesting.
Risks of Tax Loss Harvesting
- Possibility of Missing Future Gains: Harvesting at a loss locks in a negative return. If the asset rebounds, you could miss out on potential profits from a market recovery.
- Wash Sale Disqualification: If you repurchase the same or similar asset too soon, the ATO may disallow your loss as part of a wash sale, invalidating the tax benefit.
- Emotional Decision-Making: Investors may act hastily to realise tax losses without a full strategy, leading to poor portfolio outcomes driven by tax-saving goals rather than fundamentals.
- Recordkeeping Burden: Accurate transaction history, wallet tracking, and timestamps are required to validate your loss claims. Poor documentation can lead to complications during tax filing.

Conclusion
Crypto losses are not always bad news. When handled correctly, an eligible capital loss can reduce your capital gains, lower your taxable capital gain, and potentially reduce the tax you pay.
Before you harvest a loss, remember the key Australian rules:
- A crypto asset falling in value does not create a claimable capital loss until a CGT event occurs.
- Losses offset capital gains, not salary. Net capital losses cannot be used to reduce ordinary income.
- Unused losses can be carried forward to future years.
- The timing and type of disposal matter. Crypto-to-crypto swaps can trigger CGT events, and personal-use assets and other special categories have different rules.
- Capital losses are applied before the 50% CGT discount, so understanding how losses interact with discounted and non-discounted gains can affect your final tax position.
- Selling an asset has investment consequences, and transactions designed primarily to obtain a tax benefit can raise anti-avoidance concerns.
Before 30 June, review your crypto portfolio, identify unrealised losses and compare them with your realised capital gains. Use KoinX to calculate your crypto gains and losses, identify potential tax-loss harvesting opportunities and generate your Australian crypto tax report, so you can go into tax season with your numbers organised.
Frequently Asked Questions
Can I Harvest Losses From NFTs And Still Claim CGT Offsets?
Yes, you can harvest losses from NFT disposals just like cryptocurrencies, provided the NFTs are not classified as personal use or low-value collectibles. If you sell an NFT at a lower price than you purchased it for, the resulting capital loss can be used to offset gains from other crypto or NFT sales within the same financial year or future years.
Can I Use Tax Loss Harvesting if I Only Made Losses This Year?
Absolutely. If you didn’t make any capital gains in the current financial year, you can still realise and report capital losses. These losses can be carried forward and used to offset capital gains in future years. The ATO does not place an expiry on carried-forward capital losses as long as you keep valid records.
Do I Need to Harvest Losses Before a Certain Time in the Year?
Yes, you must sell the crypto asset and realise the loss before 30 June for it to apply to that financial year’s tax return. If the disposal happens after June 30, the loss will only apply to the following year. Timing matters when planning offsets, especially for capital gains incurred earlier in the same tax year.
What Crypto Transactions Cannot Be Used for Tax Loss Harvesting?
Transactions involving personal use assets or crypto worth less than AUD 10,000 used for everyday purchases are not eligible for capital loss deductions. Likewise, assets that are CGT-exempt or losses from low-value collectibles such as certain NFTs may not qualify. Always check if the asset type is recognised under ATO’s CGT rules.
