There are two kinds of tax that may apply to your Bitcoin transactions in Cash App - Capital Gains Tax and Income Tax.
Cash App provides US users who have transacted with Bitcoin with a Form 1099-B. However, as most investors are aware, most platforms have difficulty tracking cost basis if you've moved Bitcoin into your Cash App, and any Bitcoin transferred from your Cash App account to another wallet will not be included. So often, these forms are not helpful in reporting your crypto taxes.
Cash App does not provide UK users with any tax documents.
