Ouch.
Nicola Sturgeon is probably about £5,900 better off because of her move to lower-tax England. If we take into account her Scottish Parliament resettlement grant of about £74,506, her £75,000 book advance, her company dividends & the fees she gets from media appearances then she's almost certainly an additional rate taxpayer.
England applies the additional rate of 45% above £125,140, whereas Scotland applies 48% above that amount & Scotland also has higher rates on income between £29,527 & £125,140.
Nicola no doubt needs the extra money now she has to pay for her own hairdryers & coffee machines. However those who stay in Scotland still must pay the higher amounts of tax she forced on them.
