I tried to enter my US Dividends into the 23/24 on line self assessment form yesterday. As a basic rate tax payer I think that I am entitled to 8.75% of the 15% tax I have paid on the dividends in US (W-8BEN form completed). However I was not able to select 8.75% in the drop down box in the form. 7.5% is there and 8% is there but not 8.75%. Am I wrong in the % relief I should be claiming? If not should the on line form not include 8.75% in the drop down box?
