Crypto disposals under capital gains rules.
About this calculator
What it estimates
US tax on cryptocurrency disposals, which are taxed as property under capital gains rules.
Assumptions (US 2025 tax year rates)
- •Same short-term / long-term rates as the capital gains calculator
- •Each disposal — sale, swap or spending — is a taxable event
- •No state tax
Estimates only, for orientation. Rates and thresholds change each tax year and your actual liability depends on facts this tool does not ask for. This is not tax advice.
For US–UK filers
Why your real number differs
The UK also taxes crypto disposals under CGT, with a different annual exemption and different pooling rules, so the same transaction can need two different computations.
