There are the advertised tax brackets, and then there are the effective ones. The effective ones are:

0-£12,570 (0%) £12,571-£50,270 (20%) £50,271-£99,999 (40%) £100,000-£125,140 (60%) £125,141-£150,000 (40%) £150,001+ (45%)

The 60% arrises because your personal allowance is reduced by £1 for every £2 you earn over £100,000 until is disappears entirely.

Here's a nice chart that shows what % of tax you pay in combined income tax & national insurance (blue line)

And here's a chart to go along with it to show where people fit along the X axis:

But then you have to factor in National Insurance contributions, which also have a (different) threshold below which they don't cost anything, then cost you 12% up to around the £50K mark, then cost you 2% over that.

And even that isn't quite the whole story, because you'll also lose certain child-related benefits starting from £50K if you have kids, so your effective rate for the next £10K or so can work out much higher than 40%.

Then there are the effects of not-unusual things like pension contributions and charitable donations, which can move things around a bit more.

It's hardly a surprise that people find the system confusing!
