I reinvested my dividends on same day into two uk telephone company’s and a punt on a well known green company at £3.33 a share not recommending any thing. people do their own checks. I may reinvest what’s left in this share or something else.
If shares are in a ISA then no tax is due,I think if you buy shares and hold in an aim listed company for 2 years then also no tax is due. Accountant may be required.
