I too appreciate this is an older discussion but I have a similar but slightly different question please. I hold shares in a US company through Computershare, all of which were obtained through SAYE schemes many, many years ago. All dividends have been reinvested, albeit I am not under any obligation to reinvest them. Based on your reply to the previous query above, where you state that if the company automatically reinvests the dividend there is no requirement to declare them for income tax, am I wrong to have submitted the monetary value of last year's dividends on my tax return? Thank you in advance for your advices.
