A 160k annum salary used to be taxed at 45% above 150k.
So for that 10k - tax would be £4500
On that 10k now (at 40% rather than 45%), tax is now £4000
Now, that person takes home £500 pounds more than they previously would have.
They have still paid £4000 tax on it.
Yet people on here are saying ‘no, make them still pay £4500, and then we need to subside the lower earners, so actually they need to pay more’
