so if you earn 160K for example
Currently you have ......................................new rules
0% tax = none ...............................................None (your tax allowance decreases by £1 for every £2 you earn over 100K making it an effective 60% tax rate till you have no tax free allowance
20% tax = 7,540..........................................19% tax = 7,163 (377 saving)
40% tax = 39,892........................................40% tax 43,892
15% tax = 4500............................................None
total = 51,932..............................................total = 51,055
so they are getting an £877 tax reduction or less than 5% of the £20k you mention and almost half that saving comes from the reduction in the basic rate not abolition of the top)
you would actually need to earn around £1.15m for the saving to be £20k so for sure not everyone earning over £150K
And of course somebody earning over £150k is still paying about £50K each year in income tax alone which without going all west wing / sam seaborn is kinda what makes the rest of the system work
