Misspeedy - you don't have to account for it in the Ltd Co. The Ltd Co has to pay corporation tax. Dividends then come out of taxed income. Pay Divi to individual. End of story at that end.
Money gets shifted into personal income. HMRC treats it that 10% tax credit is paid. Therefore HMRC divides the divi received by 0.9 when calculating gross income. The same situation as when they deal with bank interest taxed at source, for which they use the factor 0.8 to divide by.
When working out the gross income, you have to take the earned income, plus any bank interest/0.8, plus any dividends/0.9, and keep that figure under the magic �34k (plus the personal allowance of �6k), or else you end up paying tax on the excess at 40%.
