This discussion clarifies how to declare cryptocurrency profits on your UK Income Tax Return (ITR). It explains that profits from selling crypto should be declared under the 'IFOS' (Income from Other Sources) section, specifically under 'Other' and labelled as 'Profits from Crypto'. The tax rate is a special flat rate of 30%, paid via self-assessment, and whether the gain is long-term or short-term does not affect this rate.
Then how to pay tax at special rate I.e 30% by self assessment. and weather to specify its long term or short term gain or it doesn't make any difference?
