I'm still working on updating my spreadsheet, but cannot find the definitive answer on this.
Suppose someone has a salary of £8,060 in 2016/17, interest of £8,940, and dividend of £5,000. £5,000 falls to be taxed, but is it dividend, or interest? i.e does the dividend nil rate band eat into the SRB, or the other way round?
IGNORE, It must be interest. The damned NRB for dividends doesn't erode.
