  • The figure £50,000 in large serif type, the proceeds threshold that requires capital gains to be reported to HMRC
    Crypto Tax | Self Assessment and side income

    ByZar September 13, 2026September 19, 2026

    Trading 212 does not report your trades to HMRC and the pooling rules decide what you owe

    ByZar September 6, 2026September 19, 2026

    Trading 212 sends nothing about your Invest account trades to HMRC. Gains over £3,000 are taxed at 18% or 24%, dividends over £500 at 10.75%, and the ISA sits outside all of it. The pooling rules the app does not apply.
