UK investors holding Strategy's preferred shares, STRC, listed on Trading 212, may encounter double taxation issues. While STRC distributions are tax-free in the U.S. as return of capital, UK brokers classify them as foreign dividends, subjecting them to income tax rates of up to 39.35% and capital gains tax upon sale. This results in a reduced net yield of approximately 10%. Cryptocurrency analyst James Van Straten advises UK investors to consider the 21Shares Strategy Yield ETP, available on Euronext Amsterdam and Paris. This alternative offers a zero management fee and an accumulating structure, which reinvests returns automatically, incurring only capital gains tax upon sale, thus providing better tax efficiency.
