Carry Forward Losses
Unused capital losses carried into future tax years to offset future gains and reduce tax liability.
AustraliaCanadaUnited KingdomUnited StatesUnderstanding Carry Forward Losses on crypto
When capital losses in a tax year exceed capital gains, the excess loss cannot always be used immediately. Most jurisdictions allow these unused losses to be carried forward indefinitely or for a set period to offset future capital gains. In the US, individuals can carry forward capital losses indefinitely and additionally offset up to $3,000 of ordinary income per year. In the UK, capital losses must be formally claimed and can be carried forward indefinitely. Carry forward losses are a valuable long-term tax planning tool, particularly for investors who experienced significant losses in crypto bear markets.

What this means for your crypto activity
Shelter future gains
Losses from a bear market year can shelter gains made in future bull market years.
US ordinary income offset
In the US, up to $3,000 of excess capital losses can reduce ordinary income annually while the rest carries forward.
UK reporting deadline
UK losses must be formally reported to HMRC within 4 years of the end of the tax year in which the loss arose.
Track your loss pool
You must keep records of your loss pool, as it accumulates year over year until fully used.
Personal to taxpayer
Losses cannot generally be transferred between spouses or entities — they are personal to the taxpayer.

Seeing it in action
Example scenario
Lisa realises $25,000 in crypto losses in 2022 with only $5,000 in gains, leaving a $20,000 net loss. She uses $3,000 to offset ordinary income in 2022 and carries forward $17,000. In 2024, she has $12,000 in gains — she applies $12,000 of her carried-forward loss, paying zero CGT and still holding $5,000 in loss carry-forward for future years.
How this works across jurisdictions
- Australia
Capital losses carry forward indefinitely; can only offset capital gains, not ordinary income. The ATO requires taxpayers to apply carried-forward losses to reduce current-year capital gains before applying the 12-month long-term 50% CGT discount, preventing individual investors from maximizing both benefits concurrently.
- Canada
Net capital losses carry forward indefinitely to offset future taxable capital gains; can also be carried back 3 years. The flat 50% individual inclusion rate remains structural. Unused losses carried forward must be adjusted using the CRA inclusion rate formula matching the target tax year if a future regulatory shift occurs.
- United Kingdom
Losses carry forward indefinitely but must be claimed within 4 years; set off against the first available capital gains. Because disposal tax rates have shifted to a peak 18% or 24% framework, carrying forward accumulated losses from prior low-market periods provides a higher dollar-for-dollar tax shelter against incoming gains.
- United States
Capital losses carry forward indefinitely; $3,000 per year can offset ordinary income while the remainder offsets future capital gains. With the implementation of Form 1099-DA rules for digital asset brokers, the IRS algorithmically matches carried-forward losses against incoming centralized gross proceeds and cost-basis reporting.
